Answer:
20
Step-by-step explanation:
Let
= the number of problems Anna completed
<u>Using ratios</u>
5 : 8 =
: 32

Cross multiply: 5 x 32 =
x 8
160 = 8
Divide both sides by 8: 20 = 
Therefore, Anna completed 20 problems.
Answer:
Go to the bottom half of your graph and put it on the y-axis. -7 :)
Step-by-step explanation:
The sum of all interior angles in a triangle is 180°.
m∠q + m∠r + m∠s = 180°
1x + 3x + 6x = 180
10x = 180
x = 180/10
x = 18
m∠q = (1x)° = 1 x 18 = 18°
m∠ r = (3x)° = 3 x 18 = 54°
m∠s = (6x)° = 6 x 18 = 108°
m∠s is the obtuse angle because its measure is more than 90°. Its angle measures 108°
Answer:
y = 18 when x = 3
Step-by-step explanation:
y is directly proportional to x^2, meaning:

where a is the proportion between them. We're given the values for both x and y, so plug those in and solve for a:

Now you can use a to solve for y when x is 3:

23 if you take 100 divided by four you have 25 and then minus two
