Mikayla needs to order a countertop for her project. Company \mathrm{a}a will sell mikayla a countertop according to the given graph, which includes a \$ 1,000$1,000 installation fee. Company \mathrm{b}b will sell a countertop according to the values given in the table, which includes an \$ 800$800 installation fee and a constant rate of change
Answers
Company B charges a higher rate ($20) per square foot while company A has a higher installation fee.
What is a linear function?A linear function is in the form:
y = mx + b
Where m is the rate of change, b is the initial value of y.
Let y represent the total cost of installing x ft² of countertop.
Company A passes through (0, 1000) and (10, 1150), hence:
y - 1000 = [(1150 - 1000)/(10 - 0)](x - 0)
y = 15x + 1000
Company B passes through (10, 1000) and (20, 1200), hence:
y - 1000 = [(1200 - 1000)/(20 - 10)](x - 10)
y = 20x + 800
Company B charges a higher rate ($20) per square foot while company A has a higher installation fee.

Which value of x makes the equation 0. 75(x + 20) = 2 + 0. 5(x - 2) true?
Answers
Answer:
-56
Explanation:
From the equation:
0.75(x + 20) = 2 + 0.5(x - 2)
Open brackets
0.75x + 15 = 2 + 0.5x - 1
Collect like terms
0.75x - 0.5x = 2 - 1 - 15
0.25x = - 14
Divide both sides by 0.25
x = -56

You are studying the population growth of a species of fish. Assuming unlimited resources, no predators, and a constant per capita growth rate, if the population size in 2018 was 1100 and the population size in 2019 was 1500, what will the projected population size be in 2030? when inputting your answer, write a whole number (e. G. , 1100, 1200, 1500) without decimals. If your calculation includes decimals, round up to the nearest whole number if your decimal is 0. 5 or larger, round down if your decimal is below 0. 5.
Answers
The projected population size in 2030 will be : ≈ 44159
First step : determine the population growth rate
Gr = change in population / time
= ( 1500 - 1100 ) / 1 year
= 400 = 36%
Determine the projected population sizeapplying Malthus's population projection.
Pp = P₁ ( 1 + r )ⁿ
where ; P₁ = 1500, r = 0.36 , n = ( 2030 - 2019 ) = 11 years
Pp = 1500 ( 1 + 0.36 )¹¹
= 1500 ( 29.439 )
= 44158.5 ≈ 44159
Hence we can conclude that the projected population size as at 2030 is 44159

1. The state fair sells food coupons for $2 each and
ride coupons for $3 each. If Marlon wants to buy at
least 15 coupons and spend no more than $40, what
is the largest number of ride coupons he can buy?
4.
Answers
Answer:
11
Explanation:
Food coupons is $2 each and ride coupons is $3 each.
If Marlon spends all $40 on ride coupons, he can buy 40/3 ~ 13 coupons which is less than 15 coupons that he wants.
If he gets only 12 ride coupons, he will have 40-3*12=$4 left which will let him buy 4/2=2 food coupons. Those add up to 12+2=14 coupons which is still less than 15 coupons.
So the largest number of ride coupons he can buy is 11.

A stop sign is in the shape of regular octagon. What is the measure of each of the interior angles of the stop sign?
Answers
Answer: 135 degrees
Explanation:
The measure of an interior angle of any polygon is (n-2)*180/n, where n is the number of sides in the polygon.
Since the stop sign is an octagon, there are 8 sides, so we can plug in 8 for n.
Therefore, the measure of each interior angle is (8-2)*180/8
= 6*180/8
= 1080/8
= 135 degrees
