Answer:
29.4
Step-by-step explanation:
42*0.7
Answer:
3/5=x/z
Step-by-step explanation:
7x=3y
7(3)=3(7)
21=21
5y=7z
5(7)=7z (plug in the seven from the first step)
35=7z
then divide both sides by 7
5=z
therefore, X/Z=3/5
I’m to lazy to figure out this question
Answer:
56
Step-by-step explanation:
probabilty of both being red= 0.5*0.6
total no of times spinners were spun = 84/(0.5*0.6) = 280
probabilty of both being blue= 0.5*0.4
Estimate = 0.5*0.4*280= 56
Answer:
C. 434π
Step-by-step explanation:
Given:
Radius (r) = 7 in.
Height (h) = 24 in.
Required:
Surface area of the cylinder
Solution:
S.A = 2πrh + 2πr²
Plug in the values
S.A = 2*π*7*24 + 2*π*7²
S.A = 336π + 98π
S.A = 434π
