Hope this helps!
Answer:
C) 18 square units
Step-by-step explanation:
There are many ways to go about solving this. You could divide it into two triangles with a middle section. But it might be easier just to count the squares:
whole squares = 12
half squares = 4 (which equals 2)
3/4 square = 4
1/4 squares = 4
(add the 3/4 and 1/4 squares to equal 4)
12+2+4=18

In Heavenly Hash ice cream, the ratio of the amount of cashews to the amount of marshmallows to the amount of chocolate ice cream is 1 : 3 : 36 by volume .
What is the ratio of the amount of marshmallows to ice cream?
Answer:
90%
Step-by-step explanation:
The ice cream is 1 part cashew, 3 parts marshmallow, and 36 parts chocolate ice cream. That's a total of 40 parts. So the fraction that is chocolate ice cream is:
36/40 = 0.9
So 90% of Heavenly Hash ice cream is chocolate ice cream.
In an aquarium, there are 3 red, 6 yellow, 4 white and 2 black fish. Find the ratio of the: a) Number of yellow fish to the number of white fish. b) Number of black fish to the total number of fish. c) Number of red fish to the number of black fish.
Answer:
a. 3 : 2
b. 2 : 15
c. 3 : 2
Step-by-step explanation:
Red fish = 3
Yellow fish = 6
White fish = 4
Black fish = 2
Total number of fishes = 15
a) Ratio of the Number of yellow fish to the number of white fish.
Yellow fish : White fish
6 : 4
= 6 /4
= 3/2
= 3 : 2
Ratio of the Number of yellow fish to the number of white fish = 3 : 2
b) Ratio of the Number of black fish to the total number of fish
Black fish : Total fish
2 : 15
= 2 / 15
= 2 : 15
Ratio of the Number of black fish to the total number of fish = 2 : 15
c) Ratio of the Number of red fish to the number of black fish
Red fish : black fish
= 3 : 2
= 3/2
= 3 : 2
Ratio of the Number of red fish to the number of black fish = 3 : 2

D
Step-by-step explanation:
x and y go up at a constant rate (or you can say it has a CROC or constant rate of chacge) y going up 5 for every one x
with our equation being y = 5x + 5
hope this helps <3
Answer:
Step-by-step explanation:
It would be D because to know if its linear, x has to increase by 1 and y by a constant rate.
X increases by 1 and y increases by 5

Given the system of equations presented here:
4x + y = 4
2x + 6y = 24
Which action creates an equivalent system that will eliminate one variable when they are combined?
Multiply the first equation by −4 to get −16x − 4y = −16.
Multiply the second equation by −4 to get −8x − 24y = −96.
Multiply the first equation by −2 to get −8x − 2y = −8.
Multiply the second equation by −2 to get −4x − 12y = −48.
Answer:
Multiply the second equation by −2 to get −4x − 12y = −48.
Step-by-step explanation:
Given:
4x + y = 4 (1)
2x + 6y = 24 (2)
Multiply the second equation by −2 to get −4x − 12y = −48.
4x + y = 4 (1)
−4x − 12y = −48 (3)
Variable x can be eliminated by adding the equations
4x + (-4x) + y + (-12y) = 4 + (-48)
4x - 4x + y - 12y = 4 - 48
0 - 11y = -44
-11y = -44
Divide both sides by -11
y = -44/-11
= 4
y = 4
Answer: Multiply the second equation by −2 to get −4x − 12y = −48.

Anna purchased a new car for $25,000. The car will decrease in value 15% each year.
The value of Anna's car is modeled on the graph by function f where x is the time in years after Anna purchases her car.
I will assume that we want to find the function that predicts the value of the car after x years, which likely is an exponential decay.
The function is: f(x) = $25,000*(0.85)^x
And the graph can be seen at the end of the answer.
We know that the value of the car decreases by 15% each year, then we can model this with an exponential decay.
The general exponential decay is given by:
f(x) = A*(1 - r)^x
Where:
A is the initial value, then we have A = $25,000
x is the variable, in this case, would represent time in years.
r is the rate of decay, in this case, is the quotient between the percentage that decreases and 100%, so we will get: r = 15%/100% = 0.15
Then the exponential equation is:
f(x) = $25,000*(1 - 0.15)^x
= $25,000*(0.85)^x
This is the function that models the value of the car after x years, the graph can be seen below.

1/3
Step-by-step explanation:
I have a certain way of doing this, I will start from the Y-intercept, let's say its (0, 2), then, if the next point is (3, 4) i will count up 1, to get to point 3 on the graph, then count left/right to point 4. Thus making my slope 1/2.

Angela uses a scanner to make a reduced-size (smaller) copy of a rectangular photo that is 8 inches long and 4 inches wide. The new length is 4 inches. What is its new width?
Answer:
The new width = 2 inches
Step-by-step explanation:
Original dimensions of the rectangular photo:
Length : width = 8 inches : 4 inches
Reduced dimensions of the rectangular photo:
Let
x = the new width
Length : width = 4 inches : x inches
Equate both dimensions to get the value of x
Length : width
8 inches : 4 inches = 4 inches : x inches
8 / 4 = 4 / x
Cross product
8 * x = 4 * 4
8x = 16
x = 16/8
x = 2 inches
The new width = 2 inches
