the area, a, of a trapezoid is given by the formula a=1/2h(c+d), where h is the height and c and d are the lengths of the bases rearrange the formula so that the height h of the trapezoid can be determined given the area and the lengths of the bases enter your answer in the box

Answers

Answer:

this is algebra remember algebra rules and thing really hard

Step-by-step explanation:

The formula for the height of the trapezoid will be h = 2A/(c+ d).

What is surface area?

The quantity of space enclosing a three-dimensional shape's exterior is its surface area.

In another meaning, if we say side square then it is an area of the square but for a cuboid, there are 6 faces so the surface area will be external to all 6 surfaces area.

Given a trapezoid with side lengths c and d and perpendicular distance as h

So, the area formula will be

A = (1/2)h(c + d)

Multiply both sides by 2

2A = h (c + d)

Divide by c + d into both sides

2A/(c + d) = h

Hence "The formula for the height of the trapezoid will be h = 2A/(c+ d)".

Kyle measured the length, width, and height of a donut box after all the donuts had been eaten. His measurements are shown below.
What is the volume of the donut box?

Answers

Answer:

1/6 ft³

Step-by-step explanation:

The volume of a box can be found using the following equation:

Volume of box = width x length x height.

It is given to us that:

length = 1 ft.

width = 2/3 ft.

height = 1/4 ft.

Multiply the 3 measurements together:

V (volume) = 1 x 2/3 x 1/4

V = (1 * 2 * 1)/(3 * 4) = 2/12 ft³ , or if simplified 1/6 ft³

1/6 ft³ is your answer.

~

V = Length*width*height
= (1)(2/3)(1/4)
=2/12

What is Algebra?

The area of mathematics known as algebra aids in the representation of circumstances or problems as mathematical expressions. To create a meaningful mathematical expression, it takes variables like x, y, and z together with mathematical operations like addition, subtraction, multiplication, and division.

As per the given data:

Expression:

(-8x + 2) - (6x + 9)

Simplifying to evaluate the expression:

(-8x + 2) - (6x + 9)

= -8x + 2 - 6x - 9

The graph shows the prices of different numbers of bushels of corn at a store in the current year. The table shows the prices of different numbers of bushels of corn at the same store in the previous year.

A graph shows the Number of Bushels on the x-axis and the Price of Corn in dollars on the y-axis. The x-axis scale is shown from 0 to 14 at increments of 2, and the y-axis scale is shown from 0 to 98 at increments of 14. A straight line joins the ordered pairs 2, 14 and 4, 28 and 6, 42 and 8, 56 and 10, 70 and 12, 84.

Part B: How many dollars more is the price of a bushel of corn in the current year than the price of a bushel of corn in the previous year? Show your work.

Answers

Answer:Part A:8  Part B:$1

Step-by-step explanation:

Part A: 7 dollars  

- The graph shows that 2 bushels is 14 dollars,  because the graph has a straight line, the rate remains constant you must divide the sides by two to find the amount for one bushel which would be 7 dollars.

- And to double check you would divide 28 by 4, 42 by 6, 56 by 8, 70 by 10, 84 by 11, and 98 by 12. they all equals 7 dollars So, the equation would be y = 7x.

- 7 can be known as the slope and  rate of change.

Part B:2 dollars

- The years before show 2 bushes was 10 dollars

-so you would divide 10 by two you would get five  To double check you would do the same thing with 20 by 4, 30 by 6 and 40 by 8, and they all equal 5 dollars.

-if you use this answer be sure to reword it so you dont get copy write and integrity. have a great day or night.
