Answer:

Step-by-step explanation:

divide 4 by 5 = .8 why? cuz...

To convert a fraction into a decimal, divide the top of the fraction (numerator) by the bottom of the fraction (denominator). In this case, the fraction is 4/5, so divide 4 by 5 . This equals 0.8 .

to make it more simple 4 goes into 5 once so:

1 For the denominator, recognize that 5 x 20 = 100

Multiple = 20

2 Multiply both the numerator and denominator by the multiple 20.

5×20

4×20

3 Simplify.

80

100

4 Simplify.

0.8

A cone has a base with a radius of 9 mm and a height of 13 mm. What is the volume of the cone?

$\huge\underline{\red{A}\blue{n}\pink{s}\purple{w}\orange{e}\green{r} -}$

Given - a cone with base radius 9mm and height 13 mm

To calculate - volume of the cone

We know that ,

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

substituting the values in the formula ,

$Volume = \frac{1}{3} \times 3.14 \times 9 \times 9 \times 13 \\ \\ \implies \: 1.05 \times 81 \times 13 \\ \\ \implies \: 1105.65 \: mm {}^{3}$

Help me on questions 8 through 12

mr_godi [17]

8. To find the answer you can eather multipy it for each of the sides or you can add it 6 times once for each side
$15\frac{1}{4} \times 6 \\ \\ 15 \frac{1}{4} + 15 \frac{1}{4} + 15 \frac{1}{4} + 15 \frac{1}{4} + 15 \frac{1}{4} + 15 \frac{1}{4}$
9. You basicly do the same thing as the previous problem but with the new numbers and you add each number 2 times

10. For are you multiply Base × Height So all you have to do is Multiply the 2 numbers shown together
$2 \frac{1}{2} \times 5$
11-12 Is the same but witb the new numbers

I hope this helps!

Answer:

Step-by-step explanation:

1/3 of 90

= 1/3 * 90

= 90/3

= 30

Let the missing number be x.

2/3 of x

= 2/3 * x

= 2x/3

30 = 2x/3

Cross multiply,

2x = 30 * 3

2x = 90

x = 90/2

x = 45

Hence,

the missing number is 45.
