Answer:
-100x = 10 x = 1
Step-by-step explanation:
I did the math and this is what I got
The volume of the candle initially is:
V=Ab*h
Area of the base of the cylinder: Ab=pi*r^2
pi=3.14
Radius of the base: r=4 cm
Height of the cylinder: h=6 cm
Ab=pi*r^2
Ab=3.14*(4 cm)^2
Ab=3.14*(16 cm^2)
Ab=50.24 cm^2
V=Ab*h
V=(50.24 cm^2)*(6 cm)
V=301.44 cm^3
The candle melts at a constant rate of:
r=(60 cm^3)/(2 hours)=(120 cm^3)/(4 hours)=(180 cm^3)/(6 hours)
r=30 cm^3/hour
The amount of candle melted off after 7 hours is:
A=(30 cm^3/hour)*(7 hours)
A=210 cm^3
The percent of candle that is melted off after 7 hours is:
P=(A/V)*100%
P=[(210 cm^3)/(301.44 cm^3)]*100%
P=(0.696656051)*100%
P=69.66560510%
Rounded to the nearest percent
P=70%
Answer: 70%
Answer:
it would actually be the opposite because if u multiply ur making the number higher, it can be a fraction but it would be 23/1 and thats a whole number u would need to divide by 100 and 100 bc if 10 u get 2 3/10 and if u divide by 100 u get 23/100 either way u get a fraction but if u divide by 10 u get a mixed fraction. If u just want a fraction u would have to divide from 100
Step-by-step explanation:
the same is for dividing decimals
Answer:
1) 1/10
2)16/100
3)6..../10
4) 3/5
Pls give me brainliest I rly need it!
Step-by-step explanation:
All we need to do is find 65% of 75
we need to know that 65% = 0.65
and we multiply 0.65 and 75
soooo
75 x 0.65 = 48.75
so she sould expect to make about 48 shots into the hoop
hope this helps:)
and dont forget 2
MARK ME BRAINLIEST! :D
