Question

Explain why 0.77 > 0.077

Solution 1

0.77>0.077 because when you move over in hundredths place to the right in decimals, the value of the number decreases.

Solution 2

The value of 0.77 is greater than 0.077 because 0.77 is closer to one.

Question

A set of weights includes a 4 lb barbell and 6 pairs of weight plates. Each pair of plates weighs 20 lb. If x pairs of plates are added to the barbell, the total weight of the barbell and plates in pounds can be represented by f x( ) = 20x + 4. What is the range of the function for this situation? Please explain.

Solution 1

The range of the function would be from 0 to 244.

The range of the function is the possible output values for the function. In this case, it is from zero to the highest possible weight. Since there are 6 pairs of weight plates, we can input 12 for x to get the maximum.

20(12) + 4 = 244

Question

A cylinder has a surface area of 1850 square meters and a radius of 9 meters. Estimate the volume of the cylinder to the nearest whole number. I don't understand. please help

Solution 1

Surface area of the cylinder = 1850 square meters

Radius = 9 meters

Surface area of cylinder = 2*pi*r*h

1850=2*22/7*9*h

h = 1850*7/2*22*9

= 32.7 meters

Volume of cylinder = pi*r*r*h

= 22/7*9*9*32.7

=**8324.48 = 8324 (approx) cubic meters**

Radius = 9 meters

Surface area of cylinder = 2*pi*r*h

1850=2*22/7*9*h

h = 1850*7/2*22*9

= 32.7 meters

Volume of cylinder = pi*r*r*h

= 22/7*9*9*32.7

=

Question

Solve the equation for a

w-4b = 7a

w-4b = 7a

Question

What plus what plus what equal 823

Solution 1

The answer would be 821+1+1. So as a result that would give you 823.

Hope that helped!

Hope that helped!

Solution 2

711+112=823. You can pick any number an just subtract it by 823

Question

Find the percent of decrease from 280 to 210. Round to the nearest tenth of a percent, if necessary. a 0.3% b 25% C 33.3% D 133.3%

Solution 1

I got the answer c and if I am correct then it is repeating also

Solution 2

280n = 210

Isolate n:

n = 0.75

1.0 - 0.75

**25% decrease, option b**

Isolate n:

n = 0.75

1.0 - 0.75
