Change the followong decimals to percents and order them on the number line from least to gratest useing this numbers 0.02 ' 0.9

olganol [36]

Answer:

15%

25%

90%

Step-by-step explanation:

To turn decimals to percents, you just have to times them by 100 or you can just do the quick way and move the decimal 2 places to the right.

0.02*100 = 2%

0.9*100 = 90%

0.25*100 = 25%

0.15*100 = 15%

Then, you just put them in order:

15%

25%

90%

at a reception, 23 out of 100 pieces of a wedding cake have been eaten. what decimal represents the number of pieces of cake tha

rjkz [21]

0.23 represents the number of cake pieces that have been eaten.

Step-by-step explanation:

The decimals are the end result of fractions.

Given

Total number of cake pieces = 100

Cake pieces that have been eaten = 23

So the fraction of cake pieces that have been eaten will be determined by the fraction $\frac{23}{100}$

Converting the fraction into decimal will give us 0.23

Hence,

0.23 represents the number of cake pieces that have been eaten.

The expression that represents the volume of the composite figure is $\pi (5^{2})(13) + \frac{1}{3} \pi (5^{2})(12)$ . The correct option is the third option $\pi (5^{2})(13) + \frac{1}{3} \pi (5^{2})(12)$

<h3>Calculating Volume </h3>

From the question, we are to determine the expression that represents the volume of the composite figure

The composite figure consist of a cylinder and a cone

∴ Volume of the composite figure = Volume of the cylinder + Volume of the cone

Volume of a cylinder = $\pi r^{2} h$

Where r is the radius

and h is the height of the cylinder

Volume of a cone = $\frac{1}{3} \pi r^{2} h$

Where r is the radius

and h is the height of the cone

Consider the composite figure

For the cylinder part

r = 5

h = 13

For the cone part

r = 5

h = 25 - 13 = 12

Thus,

Volume of the composite figure = $\pi (5^{2})(13) + \frac{1}{3} \pi (5^{2})(12)$

Hence, the expression that represents the volume of the composite figure is $\pi (5^{2})(13) + \frac{1}{3} \pi (5^{2})(12)$ . The correct option is the third option $\pi (5^{2})(13) + \frac{1}{3} \pi (5^{2})(12)$
