Answers
Answer:
1/25
Step-by-step explanation:
Since it only contains 1 unknown, given that r = 0, what you need to do is to substitute r=0 into the expression
= (5(0) + 1/5)^2
= (1/5)^2
=1/25
anything multiplied by 0 is 0
so 1/5 is left
5 square is 25 because 5x5 is 25
keep the numerator
so it 1/25

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 A: Describe in words how you can find the rate of change of a bushel of corn in the current year, and find the value.
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.
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)".

The correct option is 3.
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
= -8x - 6x + 2 - 9
= -14x -7
Hence, the expression evaluates to -14x - 7

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.
~
= (1)(2/3)(1/4)
=2/12
