Answer:
3/7r + 5/8s = 11
Step-by-step explanation:
r = 14
s = 8
3/7r + 5/8s = ?
3/7 (14) + 5/8 (8) = ?
3 x 2 + 5 = ?
6 + 5 = 11
Answer:
3/4 · 7/5=21/20
Step-by-step explanation:
3/4 ÷ 5/7=21/20
Hope this helps!
The circumference of a circle is equal to C=2πr
From the question, we have 615.44.
Assume that pi is equal to 3.14
Substitute and solve for r
615.44= 2(3.14)r
r= 615.44/ 6.28
r=98.4704
r=98
Therefore, the radius is about 98 units.
To check:
C=2πr
C=2 x 3.14 x 98
C=6.28 x98
C=615.44
Answer:
Step-by-step explanation:
(96 minutes)/(32 sculptures) = (96/32 minutes)/sculpture = (3 minutes)/sculpture
It takes 3 minutes to make one sculpture.
(160 balloons)/(32 sculptures) = (160/32 balloons)/sculpture = (5 balloons)/sculpture
It takes 5 balloons to make one sculpture.
(160 balloons)/(96 minutes) ≈ 1.7 balloons used per minute.
