A diagram of a spaceship ozone shield is shown below. Find the volume of the figure. ​ Figure not drawn to scale. ​Use π= 7 /22 ​and round your answer to the nearest tenth.

Answer: 1.5

Step-by-step explanation:

To find the constant ratio of successive y-values, we need to divide each y-value by the previous one.

For example, to find the ratio between the second and first y-values:

7.5 ÷ 5 = 1.5

Similarly, we can find the other ratios:

11.25 ÷ 7.5 = 1.5

16.875 ÷ 11.25 = 1.5

25.3125 ÷ 16.875 = 1.5

Since all the ratios are the same, we can conclude that the constant ratio of successive y-values is 1.5.

Therefore, the answer is c. 1.5.

Answer:

B' = (-8, -1)

C' (-1, 1)

Step-by-step explanation:

In your question, we are given A which is translated -3 units on the X axis, and translated -5 units on the Y axis.

Using this translation on points B and C we get B' = (-8, -1) and C' (-1, 1).

B = (-5, 4)

      -3, -5

B' = (-8, -1)

C = (2, 6)

     -3, -5

C' = (-1, 1)

The length of the side EF = 22.5 Units

The properties of the triangle are:

The sum of all the angles of a triangle (of all types) is equal to 180°.

The sum of the length of the two sides of a triangle is greater than the length of the third side.

In the same way, the difference between the two sides of a triangle is less than the length of the third side.

From the property of the similar triangle,

The ratio of the sides is always equal

So,

DE/EF = GH/EH

12/EF = 8/15

Cross multiply to get

(12*15)/8 = EF

180/ = 22.5

EF= 22.5 units

Therefore, the length of the EF is 22.5 Units.

Sample Response: Use the inverse operation to isolate the variable. Undo the subtraction of 4 by adding 4 to both sides of the equation. –4 + 4 = 0, and 9 + 4 is 13. The solution is q = 13. Check the solution by substituting 13 for q in the original equation, and then simplify. 13 – 4 is 9 and 9 = 9 is a true statement, so 13 is the solution.

Step-by-step explanation:

–4 + 4 = 0, and 9 + 4 is 13. The solution is q = 13. check it by taking 13 for q in the original equation, and then simplify. 13 – 4 is 9 and 9 = 9 is a true statement, 13 is the answer

The measure of angle 3 is 95°

Angles in parallel lines are angles that are created when two parallel lines are intersected by another line called a transversal.

When we have two parallel lines and they are intersected by a transversal , the angles on the parallel lines are corresponding and equal.

Therefore angle 3 = angle 7

angle 7 = 180-(angle 6) (angles on a straight line)

angle 7 = 180-85

= 95°

angle 3 = angle = 7 = 95°

Therefore the value of angle 3 is 95°

Answer: The surface area of the rectangular prism is 424 square meters.

Step-by-step explanation: To find the surface area of a rectangular prism, we need to add up the areas of all six faces.

The front and back faces have an area of length x height, which in this case is 4 x 8 = 32 square meters each.

The top and bottom faces have an area of width x height, which in this case is 15 x 8 = 120 square meters each.

The left and right faces have an area of length x width, which in this case is 4 x 15 = 60 square meters each.

So the total surface area of the rectangular prism is:

32 + 32 + 120 + 120 + 60 + 60 = 424 square meters.

Therefore, the surface area of the rectangular prism is 424 square meters.

The error that was made in finding the area of the circle is that diameter was used for radius. The correct area of the circle is: 113.10 ft²

The formula for area of a circle is expressed as:

A = πr²

where:

A is Area

r is radius

From the given circle, we are given the diameter as 12.

But radius = diameter/2 = 12/2

radius = 6

Thus, the error is that they used the diameter as radius.

Correct area of circle = π * 6²

The equation of the straight line shown in the given graph is x = -2

From the question, we are to determine the equation the given straight line in the graph

To determine the equation of the line, we will use the given two points on the line

The given points are (-2, 2) and (-2, -3)

Using the formula,

(y - y₁) / (x - x₁) = (y₂ - y₁) / (x₂ - x₁)

Substitute the given points

(y - 2) / (x - (-2)) = (-3 - 2) / (-2 - (-2))

(y - 2) / (x + 2) = -5 / (-2 + 2)

(y - 2) / (x + 2) = -5 / 0

Cross multiply

0 × (y - 2) = -5 × (x + 2)

0 = -5x - 10

Add 5x to both sides

0 + 5x = -5x + 5x - 10

5x = -10

Divide both sides by 5

5x / 5 = -10/5

x = -2

Hence, the equation is x = -2

The esteem of the annuity is roughly $21,713.22.

The intrigued (interest) earned on the annuity is roughly $14,513.22.

A. To discover the esteem of the annuity, we are able utilize the equation:

PV = C * ((1 - (1 + r)^(-n)) / r)

where PV is the display esteem of the annuity, C is the intermittent store, r is the intrigued rate per period, and n is the entire number of periods.

In this case, C = $120, r = 4.5%/2 = 0.0225 (since the intrigued is compounded semiannually), and n = 2 * 30 = 60 (since there are 2 periods per year for 30 a long time).

Stepping in these values, we get:

PV = $120 * ((1 - (1 + 0.0225)^(-60)) / 0.0225) ≈ $21,713.22

In this manner, the esteem of the annuity is roughly $21,713.22.

B. The intrigued earned on the annuity would be the overall esteem of the annuity short the entire sum stored over the 30-year period. The full sum kept would be:

Add up to Stores = $120 * 2 * 30 = $7,200

So the intrigued earned would be:

Intrigued = $21,713.22 - $7,200 = $14,513.22

The correlation coefficient for the data shown in the table is: B. -1.

In order to calculate or determine the correlation coefficient for the data shown in the table (see attachment), we would have to determine the slope of the line based on the points as follows;

In Mathematics and Geometry, the slope of any straight line can be determined by using the following mathematical equation;

Slope (m) = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = (10 - 15)/(5 - 0)

Slope (m) = -5/5

Slope (m) = -1.

Slope (m) = (5 - 10)/(10 - 5)

Slope (m) = -5/5

Slope (m) = -1.
