The volume of a cube is 528cm cubed. work out the length of its side rounded to 1DP

8.1

Step-by-step explanation:

Formula for volume of cube. V = Volume and A = Edge.

Therefore we have.

We have to use the cube root function.

The cube root of (n) is the same as (n) raised to the 1/3 power.

n = a number

So then we have.

Round to 1 decimal place.

The answer is in the image 

Cost of 7 gallons=$24.50

Cost of 1 gallon=24.50/7=3.5

Cost of 15 gallons=15*3.5=52.5

Cost of 15 gallons will be $52.5

For 1 flavor there are 9 topping

Therefore, for 5 different flavors there will be 5*9 choices

No of choices= 5*9

=45 

The answer is in the image 

The solution is in the following image

y=2x+15

where y=Value of coin

x=Age in years

Value of coin after 19 years=2*19+15

=$53

Therefore, Value after 19 years=$53

The answer is in the image 

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg
