Answer:11.9 inches
Step-by-step explanation:
Circumference(c)=75inches
Pi=3.14
Circumference(c)=2 x π x radius(r)
75=2 x 3.14 x r
75=6.28 x r
Divide both sides by 6.28
75 ➗ 6.28=(6.28 x r) ➗ 6.28
11.9=r
Therefore radius=11.9 inches
Allison can make four parfaits because you need 1/8 cup of yogurt and Allison has 1/2 cup of yogurt. So the half of the cup would give her 4 * 1/8 to equal 1/2.
When you add the degrees of all the angles in a triangle you should get 180
A= 5x+5
B= 90
C= 3x+5
5x + 3x = 8x
5 + 90 + 5 = 100
8x + 100 = 180 this is the equation
-100 -100
————————
8x = 80 ➡️ divide BOTH sides by 8
x = 10
Now plug 10 into angles A and C
5(10)+5= 55
3(10)+5= 35
A= 55 , B= 90 , C=35
