Answer:
40.5 m²
Step-by-step explanation:
Area of the shaded = area of the square - area of the triangle
Area of square = s²
s = 9 m
Area of square = 9² = 81 m²
Area of triangle = ½*b*h
b = 9 m
h = 9 m
Area of triangle = ½*9*9 = 40.5 m²
Area of the shaded = 81 - 40.5 = 40.5 m²
6/10 x 10/1
6 x 10 = 60
10 x 1 = 10
60/10 = 6
1/2 x 10/1
1 x 10 = 10
2 x 1 = 2
10/2 = 5
3/4 x 20/1
3 x 20 = 60
4 x 1 = 4
60/4 = 15
For a one-to-one function, f(x) = f(y).
So, lets find f(x) and f(y).
We know,
f(x) = (x - 2)³ + 8
Now,
f(y) = (y - 2)³ + 8
Now, we said earlier, for a function to be one-to-one, f(x) = f(y).
Therefore,
f(x) = f(y)
(x - 2)³ + 8 = (y - 2)³ + 8
(x - 2)³ = (y - 2)³
x - 2 = y - 2
x = y
Since we got x = y, we know for every x, there is one and only one y. Therefore, the function is one-to-one function.
Renee needs to hike 2 miles to finish the hiking trail
The first step is to add the both miles
She hiked for 4 1/4 miles= 17/4
After resting she then hiked for another 3 1/2 miles= 7/2
17/4 + 7/2
= 31/4
The hiking trail is 9 3/4
To find the number of miles let to finish the trail, let's subtract 31/4 from 9 3/4
39/4 -31/4
= 8/4
= 2
Hence Renee needs to hike for 2 miles to finish the hiking trail

Answer:
a) 4 quarts of sparkling water
b) 38.5 quarts of grape juice
c) 80 quarts of sparkling water and 20 quarts of grape juice
The answers for the letters in the chart are on the bottom for b and c.
Step-by-step explanation:
a) You would need 4 quarts of sparkling water for 1 quart of grape juice.
This proportion is to get the amount of grape juice you need you multiply the amount of sparkling water by .25 to get the amount of grape juice you need.
So for a) I know that .25 of a quart of grape juice is equal to 1 quart of sparkling water. So to get the amount of sparkling water multiply the amount of grape juice you need by .25. And the number you multiplied .25 will be the amount of sparkling water you need. Example: <u>4</u> × .25 = 1 quart of grape juice.
4 is the amount of sparkling water you need.
b) For b you just need to multiply the amount of sparkling water by .25 to get the amount of grape juice you need.
154 × .25 = 38.5
You need 38.5 quarts of grape juice.
c) You would need 80 quarts of sparkling water and 20 quarts of grape juice.
80 × .25 = 20
b on the graph is 38.5 because 154 × .25 = 38.5
c on the graph is 400 because .25 × 400 = 100
HOpe this helps ya!!
