Step 1
(r+4-2r-14)>0 equation/Question
Step 2
(r+4-2r-14)>0 Simplify to remove parenthesis
-r-10>0
Step 3
-r-10>0 Add 10 to sides
-r-10+10>0+10
-r>10
Step 4
-r/-1>10/-1 cross multiply (which also means divide)
answer
r<-10
Area of a cylinder is the area of the top + the area of the bottom + the area of the wrap-around (lateral)
top: pi*r*r=81pi
bottom: 81pi
lateral: 2pi*r*h=18pi*h, h is unknown, but you don't have to solve it.
add them up: 81pi +81pi + 18h*pi=1850
pi*h=(1850-162pi)/18, (plug this in the volume formula below.)
volume of a cylinder: the area of the base × the height =81pi*h
volume=81[1850-162pi)/18]
use your calculator: V=6036
please double check my calculation by yourself.
Answer:
$1200 interest
Step-by-step explanation:
$30,000 divided by 100 = 300 , 300 multipled by 4 = 1200 , thats how to find what 4% would be
Answer:
the probability of the computer chip produced and defective is 0.003825
Step-by-step explanation:
The computation of the probability of the computer chip produced and defective is shown below
= Produced percentage × defective percentage
= 45% × 0.85%
= 0.003825
Hence, the probability of the computer chip produced and defective is 0.003825
The same is considered and relevant too
Answer:
The radius is 1.75 cm, 1 3/4 cm, or 7/4 cm (all the same, just in different forms)
The circumference in terms of π is 7/2(π) cm, 3.5(π), or 3 1/2(π) cm (all the same, just in different forms)
The approximate circumference of the circle is 10.99 or 11 cm. (don't know if it's supposed to be rounded)
Step-by-step explanation:
Radius = 1/2 of the diameter, so 1/2 of 7/2 is 1.75, 1 3/4, or 7/4 cm.
Circumference in terms of pi means to not approximate pi. Circumference of circle is πd, so the exact circumference would be 7/2 pi cm, 3.5 pi cm, or 3 1/2 pi cm.
3.5 x 3.14 = 10.99. 10.99 cm ≈ 11 cm.
