The equation or system of equations that can be used to determine the number of cats and dogs Bea has in her pet shop is d = 2c - 5 d + 3 = c + 3. We can solve the system of equations using substitution and plug it back into either equation to find the value of d, which is 8 cats and 10 dogs.

The equation or system of equations that can be used to find the number of cats and dogs Bea has in her pet shop is:

d = 2c - 5

d + 3 = c + 3

No, Bea's Pet Shop could not initially have 15 cats and 20 dogs. This is because the equation or system of equations states that the number of dogs is five less than twice the number of cats, which would mean that 15 cats would result in 25 dogs, which is not equal to 20.

To determine algebraically the number of cats and the number of dogs Bea initially had in her pet shop, we can use the equation or system of equations that we previously created.

d = 2c - 5

d + 3 = c + 3

We can solve the system of equations using substitution:

d = 2c - 5

d + 3 = c + 3

d + 3 = c + 3

d = c + 3

2c - 5 = c + 3

2c = c + 8

c = 8

Once we determine the value of c, we can plug it back into either equation to find the value of d:

d = 2(8) - 5

d = 15 - 5

d = 10

Therefore, Bea initially had 8 cats and 10 dogs in her pet shop.

The length of ST in the triangle STU, we can use the sine rule. Given that the measure of angle ZU is 90°, angle ZT is 26°, and US is 13 feet, we can calculate the length of ST to the nearest tenth of a foot. Therefore, the length of ST in the triangle STU is approximately 5.45 feet.

In triangle STU, we have angle ZU as a right angle, which means triangle STU is a right triangle. The sine rule can be used to relate the lengths of the sides and the measures of the angles in a triangle. The sine rule states that in any triangle, the ratio of a side length to the sine of its opposite angle is constant.

Using the sine rule, we can write:

ST / sin ZT = US / sin ZU

Given that sin ZU = 1 (since ZU is a right angle), and US = 13 feet, we can substitute these values into the equation:

ST / sin 26° = 13 / 1

To find the length of ST, we can solve for it:

ST = sin 26° * 13

Evaluating the right-hand side of the equation, we find:

ST ≈ 5.45 feet (rounded to the nearest tenth of a foot)

Therefore, the length of ST in the triangle STU is approximately 5.45 feet.

Another possible vertex of the square is determined as (2, 1).

option B is the correct answer.

The vertex of a figure is the point of intersection of two sides of the shape.

The perimeter of the square is given as 12 units, the length of each side of the square is calculated as follows;

P = 12 units

a side length = 12 units / 4 = 3 units

To determine another possible vertex of the square, the length between the points must be equal to 3.

Let's consider point A;

A = (1, 2)

given vertex = (-1, 1)

distance between the points = √ (-1 -1)² + (1 - 2)² = √5

Let's consider point B;

B = (2, 1)

given vertex = (-1, 1)

We need 1.75 litres of water to make 2 litres of diluted squash with a ratio of 1 part squash to 7 parts water

To make 2 litres of diluted squash with a ratio of 1 part squash to 7 parts water, we need to calculate how much water is needed.

We can do this by using the following formula:

Water = Diluted Squash - Squash First, we need to find out how much squash is in 2 litres of diluted squash.

Since the ratio is 1:7, we can divide 2 litres by the total number of parts (1 + 7 = 8) to find out how much squash is in 2 litres of diluted squash: Squash = 2 litres / 8 = 0.25 litres

Now we can use the formula to find out how much water is needed:

Water = 2 litres - 0.25 litres = 1.75 litres

Therefore, we need 1.75 litres of water to make 2 litres of diluted squash with a ratio of 1 part squash to 7 parts water.

Step-by-step explanation:

The measure of the angle the ramp makes with the ground is approximately 30 degrees.

We have,

To find the measure of the angle the ramp makes with the ground, use trigonometry.

In this case, a right triangle is formed by the ramp, the ground, and the vertical height of 1 meter.

Denote the angle the ramp makes with the ground as θ (theta).

Using the trigonometric function "sine" (sin), we can set up the following equation:

sin(θ) = opposite/hypotenuse

The opposite side is the height of the ramp, which is 1 meter, and the hypotenuse is the length of the ramp, which is 2 meters.

So,

sin(θ) = 1/2

θ = arcsin(1/2)

Using a calculator or a trigonometric table.

θ = arcsin(1/2) = 30 degrees.

Therefore,

The measure of the angle the ramp makes with the ground is approximately 30 degrees.

Yes, they have the same solution.

Step-by-step explanation:

Both of these equations have the same solution, just different steps.

To solve Ravi's equation, first we use the distributive property.

2(x+14) = 40

Multiply 2 by x and 14

2x + 28 = 40

Subtract 28 from both sides.

2x + 28 - 28 = 40 - 28

2x = 12

Divide by 2 on both sides.

2x/2 = x

12/2 = 6

so x = 6.

Fran's equation is the same equation as Ravi's second step.

The vertical distance between the windows is approximately 10.07 meters.

To find the vertical distance between the windows, we can use trigonometry. Let's consider the observer's line of sight as a line from the observer's position to the top window. This forms a right triangle with the vertical distance between the windows as the opposite side, the horizontal distance as the adjacent side, and the line of sight as the hypotenuse.

Using the trigonometric function tangent, we can calculate the vertical distance:

For the top window:

tan(71° 4') = vertical distance / 12 m

Solving for the vertical distance gives:

vertical distance = 12 m * tan(71° 4')

For the bottom window:

tan(61° 56') = (vertical distance + x) / 12 m

Solving for the vertical distance gives:

vertical distance + x = 12 m * tan(61° 56')

Now, subtracting the two equations, we get:

x = 12 m * (tan(61° 56') - tan(71° 4'))

Substituting the values and calculating, we find that the vertical distance between the windows is approximately 10.07 meters.

The exact value of the expression is therefore -1/2 - √3, which is option B.

Given that cos 120 tan 60°We know that the trigonometric functions are periodic in nature, and have values at each of the quadrant angles. Thus we can manipulate the given expression to determine an exact value:

cos 120 tan 60° = cos (120 + 180) tan (60 + 180)

Since the cosine function is negative in the second quadrant, and tangent is negative in the third quadrant, we can find exact values for the cosine and tangent of the quadrant angles 120 + 180 and 60 + 180, respectively.

Using the reference angles of 120 and 60 degrees, respectively, we can write:

cos (120 + 180) tan (60 + 180)

= -cos 120 -tan 60

= -(1/2) - √3

In statistical analysis, a relationship might appear in a sample even though it does not exist in the population due to sampling error. This occurs when the sample is not fully representative of the population, leading to discrepancies between the sample statistics and the true population parameters.

Sampling error can cause random fluctuations that mistakenly suggest a relationship, which may not be present in the larger population. It is important to consider the limitations and potential sources of error when generalizing findings from a sample to the broader population. So b option is correct.

Using the sine rule, the value of d in the triangle is 28.98 degrees.

The side of a triangle can be found using the sine rule. The sine rule can be represented as follows:

a / sin A = b / sin B = c / sin C

Therefore,

38.5 / sin 65 = d / sin 43°

cross multiply

38.5 × sin 43° = d sin 65°

divide both sides by sin 65°

d = 38.5 × sin 43° / sin 65

d = 38.5 × 0.68199836006 / 0.90630778703

d = 26.256615 / 0.90630778703

Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.

Any of the multiple sets of symbols and the guidelines for utilizing them to represent numbers are included in the Number System.

Given the numbers is  (5 x 1,000,000) (6 x 100,000) (4 x 10,000) (8 x 1,000) (3 x 100) (2 x 10) (4 x 0.1) (9 x 0.001)

Now standard form means we need to write the exponents form.

So,

5 x 6 x 4 x 8 x 3 x 2 x 4 x 9 = 207360

And

1,000,000 x  100000 x 10000 x 1000 x 100 x 10 x 0.1 x 0.001 = 10¹⁷
