5 12 13 triple
Answer:
r =5
Step-by-step explanation:
We can use the Pythagorean theorem
a^2 + b^2 = c^2
The legs are r and 12
The hypotenuse is (8+r)
r^2 + 12^2 = (8+r)^2
r^2 + 144 = 64 + r^2 +16r
Subtract r^2 from each side
144 = 64 +16r
Subtract 64 from each side
144-64 = 16r
80 = 16r
Divide each side by 16
80/16 = 16r/16
5 =r

Answers
Answer:You just divide the original amount by 100 (move the decimal point over two places)
750 / 100 = 7.5
Now you multiply that by the interest rate, which in this case is 7.
7.5 x 7 = 52.5
Now finally, you multiply that by the amount of years. In this case, 3.
52.5 x 3 = 157.5
That would be the amount added after three years! Remember, this is simple interest. Compound interest is a little more complex.

There are 10 red, 10 blue, 10 green, and 10 yellow marbles in bag. A student pulled a marble, recorded the color, and placed the marble back in the bag. The table below lists the frequency of each color pulled during the experiment after 40 trials.
Outcome Frequency
red 8
blue 12
green 9
yellow 11
Compare the theoretical probability and experimental probability of pulling a red marble from the bag.
The theoretical probability, P(red), is 20%, and the experimental probability is 25%.
The theoretical probability, P(red), is 25%, and the experimental probability is 20%.
The theoretical probability, P(red), is 50%, and the experimental probability is 20%.
The theoretical probability, P(red), is 25%, and the experimental probability is 8%
Answers
Step-by-step explanation:
The theoretical probability of pulling a red marble from the bag can be calculated by dividing the number of red marbles by the total number of marbles:
P(red) = 10/40 = 1/4 = 0.25 = 25%
The experimental probability of pulling a red marble is the frequency of red marbles pulled divided by the total number of trials:
Experimental probability of pulling a red marble = 8/40 = 0.2 = 20%
Therefore, the theoretical probability of pulling a red marble is 25%, and the experimental probability is 20%.
So the answer is: The theoretical probability, P(red), is 25%, and the experimental probability is 20%.
Please Mark As Brainliest
P(red) = 10/40 = 1/4 = 0.25 = 25%

cassie is placing stickers on a page that is 12 inches long and 8 inches wide the sticker are 3 inches long and 2 inches wide
Answers
Answer:
To find the greatest number of stickers Cassie can place on a page that is 11 inches long and 8 inches wide without them overlapping, we need to use the same approach as before.
Firstly, we need to calculate the maximum number of stickers that can fit along the length of the page, which is now 11 inches. Since each sticker is 3 inches long, we can fit 3 stickers along the length (11 ÷ 3 = 3 with a remainder of 2).
Next, we can calculate the maximum number of stickers that can fit along the width of the page, which is still 8 inches. Since each sticker is 2 inches wide, we can fit 4 stickers along the width (8 ÷ 2 = 4).
To ensure that the stickers do not overlap, we can only use the full row of 3 stickers from the previous calculation. Therefore, we can place 3 stickers along the length and 4 stickers along the width, giving us a maximum of 12 stickers that Cassie can place on the page without them overlapping.
Step-by-step explanation:
Answer:
16
Step-by-step explanation:
First, find out how much stickers you can put on the long side:
12/3 = 4
Next, find out how much stickers you can put on the wide side:
8/2 = 4
Lastly, calculate them together:
4x4=16
So the answer is 16.
The figure shows a rectangle inscribed in a circle that has a diameter of 10 feet. Which measurement is closest to the area of the shaded portion of the figure in square feet.
A. 314 ft²
B. 78.5 ft²
C. 266 ft²
D. 30.5 ft²
Answers
The shaded portion of the figure in square feet is 78.5 ft².
What is Area?Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. The area of a plane figure is the area that its perimeter encloses.
As, its diagonal is equal to the diameter of the circle which is 10 feet.
Let the width of the rectangle be x, then its length is 10-x.
Using the Pythagorean theorem, we can write:
x² + (10-x)² = 10²
2x² - 20x + 100 = 100
2x² - 20x = 0
2x(x-10) = 0
x =10, which means the rectangle is actually a square.
Therefore, its area is 10² = 100 square feet.
Now, the area of the shaded portion is
= area of the circle - area of the square.
Then, Radius is 5 feet.
So, the area of the circle
= π(5²)
= 25π square feet.
Therefore, the area of the shaded portion is:
= 25π - 100
≈ 78.5 square feet.

You have a deck of cards and draw three cards one after the other without replacing the cards. What is the probabilities of drawing three tens? (Pls give a good explanation & the answer lol)
Answers
Answer:
The probability of drawing 3 tens one after another without replacing them is 1/5525
Step-by-step explanation:
In a pack of 52 cards, there are 4 cards that are 10, so the probability of drawing one ten [p(10)] = 4/52
Therefore:
The first draw, P(10) = 4/52
Now, at this point you have taken out one of the cards with a number 10 printed on it, so we are left with 51 cards in total and 3 cards of 10.
The second draw, p(10) = 3/51
Now, we have 50 cards left and a total of 2 cards with a number 10 printed on it.
The third draw, p(10) = 2/50
Hence, the probability of drawing out 3 number 10 cards without replacement is:
4/52 * 3/51 * 2/50 = 1/5525
The probability of drawing 3 tens one after another without replacing them should be 1/5525.
Calculation of the probability:Since we know that
In a pack, there are 52 cards and there are 4 cards that are 10,
so the probability of drawing one ten [p(10)] = 4/52
Now it should be left with 51 cards in total and 3 cards of 10.
So, The second draw, p(10) = 3/51
and, The third draw, p(10) = 2/ 50
Thus, the total probability is
= 4/52 * 3/51 * 2/50
= 1/5525

How many more cars were sold during the second quarter of 1999 than in the second quarter of 1998? Explain how you got your answer. (2-step question)
Answers
Answer:
Part 1: How many cars were sold at Frank's Auto Corner during the second quarter of 1999? 302 cars
Part 2: How many more cars were sold during the second quarter of 1999 than in the second quarter of 1998? 15 cars
Step-by-step explanation:
Part 1: How many cars were sold at Frank's Auto Corner during the second quarter of 1999?
How to: Add the number of cars sold during April, May, and June of 1999. This would be: 89 + 98 + 115 = 302 cars
Part 2: How many more cars were sold during the second quarter of 1999 than in the second quarter of 1998?
How to: Subtract the number of cars sold in the second quarter of 1998 from the number sold in second quarter 1999. We are given that 287 cars were sold in the second quarter of 1998 so: 287 - 302 = 15 cars

The angles are;

What is the cosine rule?The cosine rule is a mathematical formula used in trigonometry to determine the lengths of sides of a triangle, given the lengths of two sides and the measure of the angle between them. The cosine rule states that the square of the length of a side of a triangle is equal to the sum of the squares of the lengths of the other two sides, minus twice the product of the lengths of those sides and the cosine of the angle between them.
c^2 = a^2 + b^2 - 2abCos C
7^2 = 5^2 + 8^2 - 2(5 *8) Cos C
49 = 25 + 64 - 80 CosC
-40 = -80 CosC
Cos C = 0.5
C = 60°
b^2 = a^2 + c^2 - 2ac Cos B
5^2 = 8^2 + 7^2 - 2(8 *7) Cos B
25 = 64 + 49 - 112Cos B
Cos B = 38
C = 180 - (60 + 38)

An object has a mass of 17 grams.
What is its weight in ounces?
Use 1 ounce=28.35 gram to write the conversion facto
Answers
Step-by-step explanation:
In order to determine the weight of an object in ounces, we need to convert its mass from grams to ounces using the conversion factor of 1 ounce = 28.35 grams. Since the mass of the object is 17 grams, we can use the conversion factor to calculate its weight in ounces as follows:
17 grams * (1 ounce / 28.35 grams) = 0.6 ounces
Therefore, the weight of the object in ounces is 0.6 ounces. The conversion factor used in this calculation is 1 ounce = 28.35 grams.

(3*4*1/2)=6
Then, we multiply the above equation by the Height. Which makes the equation become 60.
The first step for the second picture is the same. We first find the area of the triangle on top.
(12*9*1/2)=54
Then we multiply the height by our above answer.
