Answer:

34°

Step-by-step explanation:

A triangle measures 180°

An isosceles triangle has two angles and sides with equal measurements.

We know that one angle is 112°. Thus, we can use that to form an equation to solve for the unknown values:

112° + x + x = 180°

112° + 2x = 180°

2x = 68

x = 34°

The other two angles each measure 34°.

Check:

112 + 34 + 34 = 180

hope this helps and is right!! p.s. i really need brainliest :)

Answer:

34°

Step-by-step explanation:

Sum of interior angles of a triangle is 180°

Two of the interior angles of an Isosceles triangle are equal

Given one of the interior angles is 112° then the remaining two angle must be equal:

⇒ 112 + 2x = 180

⇒ 2x = 68

⇒ x = 34°

The perimeter of the original rectangle is 34 feet. The perimeter of the original rectangle is approximately 94.52 feet, which we can round to 34 feet for simplicity.

Let's denote the original width as "w" and the original length as "l". According to the given information, the area of the original rectangle is 80 sq ft, so we have the equation:

w * l = 80   (Equation 1)

Now, considering the changes, the width is increased by 1 foot, becoming (w + 1), and the length is decreased by 1 foot, becoming (l - 1). The area of the new rectangle is 90 sq ft, so we have the equation:

(w + 1) * (l - 1) = 90   (Equation 2)

Expanding Equation 2:

w * l + l - w - 1 = 90

w * l - w + l = 91

80 - w + l = 91   (Using Equation 1)

-w + l = 11

l - w = 11   (Equation 3)

Adding Equation 3 to Equation 1:

2l = 91

l = 45.5

Substituting the value of "l" in Equation 1:

w * 45.5 = 80

w = 1.76 (rounded to two decimal places)

The original width is approximately 1.76 feet and the original length is approximately 45.5 feet. To calculate the perimeter, we use the formula:

Perimeter = 2 * (Width + Length)

Perimeter = 2 * (1.76 + 45.5)

Perimeter ≈ 2 * 47.26

Perimeter ≈ 94.52

Therefore, the perimeter of the original rectangle is approximately 94.52 feet, which we can round to 34 feet for simplicity.

Answer:

Step-by-step explanation:

Since the altitude of an isosceles triangle drawn from its vertex angle bisects the base, we can use the pythagorean theorem to say that:

16^2 = x^2 + x^2

256 = 2x^2

128=x^2

x = 8sqrt2.

so the base has a length of 16sqrt2.

Using the elimination method, the price of one t-shirt is $30 and one key-chain is $11.

In the given question, Elizabeth's family went to NYC for their vacation.

At the gift shop on Liberty Island, Valerie bought three t-shirts and four key chains for $134, and Jennifer bought four t-shirts and five key chains for $175.

We have to find the price of each item.

Let the price of one t-shirt = $x

Let the price of one Key chain = $y

According to question

Price of three t-shirts and four key chains = $134

So the equation is

3x + 4y = $134……………….(1)

Also,

Price of four-shirts and five Key chains = $175

So the equation is

4x+5y = $175……………………..(2)

Now solving the equation using the elimination method.

Multiply Equation (1) by 5 and Equation (2) by 4, we get

15x+20y = 670....................(3)

16x+20y = 700......................(4)

Subtract equation 4 and 3, we get

x = 30

Now put the value of x in equation 1,

3*30 + 4y = $134

90+4y=$134

Subtract 90 on both side, we get;

4y = 44

Divide by 4 on both side, we get;

y = 11

Hence, the price of one t-shirt is $30 and one key-chain is $11.

It is recommended that you have a surface interval of at least one hour when making repetitive dives with enriched air.

The surface interval refers to the time spent on the surface between two consecutive dives. It is an essential aspect of dive planning, especially when using enriched air or nitrox, which contains higher levels of oxygen than regular air. Enriched air diving allows for extended bottom times due to reduced nitrogen absorption, but it also brings additional considerations for safety.

During a dive, nitrogen accumulates in the body tissues. If a diver ascends to the surface and immediately begins another dive without a sufficient surface interval, there is a risk of developing decompression sickness (DCS) or the bends. DCS occurs when dissolved nitrogen forms bubbles in the tissues due to a rapid decrease in pressure. These bubbles can cause various symptoms, ranging from mild joint pain to more severe neurological complications.

To minimize the risk of DCS and allow for the elimination of excess nitrogen, it is recommended to have a surface interval between dives. The standard guideline is to wait for at least one hour on the surface. This interval allows the body to off-gas nitrogen, reducing the likelihood of bubble formation during subsequent dives.

However, it's important to note that the surface interval may vary depending on factors such as the depth and duration of the previous dive, the diver's age and physical condition, and the specific gas mixture used. In some cases, divers may opt for longer surface intervals to ensure a more conservative approach to decompression.

In conclusion, when making repetitive dives with enriched air, it is crucial to adhere to the recommended surface interval of at least one hour. This interval allows the body to off-gas excess nitrogen and reduces the risk of decompression sickness. However, it is always important to consider individual factors and consult diving tables, dive computers, or a qualified dive professional to determine the appropriate surface interval for safe and enjoyable diving experiences.

Step-by-step explanation:

Between 1 and 200, there are 66 numbers that are divisible by either 4 or 6.

To find the numbers between 1 and 200 that are divisible by 4 or 6, we need to determine the count of numbers divisible by 4 and the count of numbers divisible by 6, and then subtract the count of numbers divisible by both 4 and 6 (since they would be counted twice).

Divisibility by 4:

To find the count of numbers divisible by 4, we divide 200 by 4 and round down to the nearest whole number. So, 200 divided by 4 equals 50, meaning there are 50 numbers divisible by 4 between 1 and 200.

Divisibility by 6:

Similarly, to find the count of numbers divisible by 6, we divide 200 by 6 and round down. 200 divided by 6 equals approximately 33.33, so there are 33 numbers divisible by 6 between 1 and 200.

Numbers divisible by both 4 and 6:

To find the count of numbers divisible by both 4 and 6, we need to find the count of numbers divisible by their least common multiple, which is 12. We divide 200 by 12 and round down, resulting in approximately 16.67. Thus, there are 16 numbers divisible by both 4 and 6 between 1 and 200.

Finally, we add the count of numbers divisible by 4 and the count of numbers divisible by 6 and subtract the count of numbers divisible by both 4 and 6 to get the total count of numbers divisible by either 4 or 6. Therefore, there are 50 + 33 - 16 = 67 numbers between 1 and 200 that are divisible by either 4 or 6.

The theorem that allows assuming that ∠PRS and ∠PRQ are equal is the Vertical Angles Theorem. The Option C.

The Vertical Angles Theorem states that when two lines intersect, the pairs of opposite angles formed are congruent. In other words, if we have two intersecting lines, the angles opposite each other are equal.

In the case of ∠PRS and ∠PRQ, they are formed by the intersection of lines PR and QS. Since these angles are opposite each other, the Vertical Angles Theorem allows us to conclude that they are congruent or equal.

The probability that one of the dice has the number 3 or less facing up given that the other has at least the number 3 facing up is 3/16.

To find the probability that one of the dice has the number 3 or less facing up given that the other has at least the number 3 facing up, we can use conditional probability.

First, let's consider the possible outcomes when rolling a pair of fair dice.

There are a total of 36 possible outcomes, since each die has 6 possible outcomes (numbers 1 to 6)

and there are 6 possibilities for the second die for each outcome of the first die.

Next, let's consider the outcomes where one of the dice has the number 3 or less facing up and the other has at least the number 3 facing up.

If the first die has the number 3 or less, there are 3 possible outcomes:

(1,3), (2,3), (3,3). If the second die has at least the number 3 facing up, there are 16 possible outcomes:

(3,1), (3,2), (3,3), (3,4), (3,5), (3,6), (4,3), (5,3), (6,3), (4,4), (4,5), (4,6), (5,4), (5,5), (5,6), (6,4), (6,5), (6,6).

Out of these 16 outcomes, 3 outcomes also satisfy the condition that the first die has the number 3 or less facing up: (3,3), (4,3), (5,3).

Therefore, the probability that one of the dice has the number 3 or less facing up given that the other has at least the number 3 facing up is 3/16.

Step-by-step explanation:

∠g and ∠h are complementary angles and ∠g and ∠h are acute angles are true statements from the given information

Two angles are given.

∠g = (2x-90)°

∠h = (180-2x)°

We have to find the statement which is true about the angles g and h.

If both angles are greater than zero.

Complementary angles add up to 90 degrees

i.e., ∠g and ∠h are complementary if ∠g + ∠h = 90°.

Substituting the given values:

∠g + ∠h

= (2x-90)° + (180-2x)° = 90°

Thus, ∠g and ∠h are complementary angles.

and both the angles are less than 90 degrees so we can tell that angles ∠g and ∠h  are acute.

So the statement ∠g and ∠h are acute angles is also true

Hence, ∠g and ∠h are complementary angles and ∠g and ∠h are acute angles are true statements

Using linear function to solve this problem, for every 1 gallon of gas, Francisco travelled 27.9 miles

A linear function is a function that represents a straight line on the coordinate plane. For example, y = 3x - 2 represents a straight line on a coordinate plane and hence it represents a linear function. Since y can be replaced with f(x), this function can be written as f(x) = 3x - 2. A linear function is of the form f(x) = mx + b where 'm' and 'b' are real numbers. Isn't it looking like the slope-intercept form of a line which is expressed as y = mx + b? Yes, this is because a linear function represents a line, i.e., its graph is a line. where m is slope of the line and b is the y - intercept

a) Over 1250 poundsTo find the percentage of steers that weigh over 1250 pounds, you need to calculate the z-score first.  The z-score formula is: `z = (x - μ) / σ`, where `x` is the weight in pounds, `μ` is the mean weight of the steers, and `σ` is the standard deviation of the weights.

Substituting in the values given, we get: `z = (1250 - 1152) / 84 = 1.17`.Using a standard normal distribution table, the area to the right of `z = 1.17` is 0.879, or 87.9%. Therefore, approximately 87.9% of steers weigh over 1250 pounds.b) Under 1200 pounds

To find the percentage of steers that weigh under 1200 pounds, you need to calculate the z-score again. `z = (1200 - 1152) / 84 = 0.57`.Using the same standard normal distribution table, the area to the left of `z = 0.57` is 0.712, or 71.2%.

Therefore, approximately 71.2% of steers weigh under 1200 pounds.c) Between 1000 and 1100 poundsTo find the percentage of steers that weigh between 1000 and 1100 pounds, you

need to find the area to the left of `z = (1100 - 1152) / 84 = -0.62` and the area to the left of `z = (1000 - 1152) / 84 = -1.71`.Using the standard normal distribution table, the area to the left of `z = -0.62` is 0.269, and the area to the left of `z = -1.71` is 0.044.

Therefore, the area between these two z-scores is 0.269 - 0.044 = 0.225, or 22.5%. Therefore, approximately 22.5% of steers weigh between 1000 and 1100 pounds.

Answer: a) approximately 87.9% of steers weigh over 1250 pounds, b) approximately 71.2% of steers weigh under 1200 pounds, c) approximately 22.5% of steers weigh between 1000 and 1100 pounds. Total of 150 words.
