Answer:

D. 1356.5 cm³

Step-by-step explanation:

The volume of a cone can be represented by:

V = (π)(r²)(h/3)

Substitute the known values:

π = 3.14

r = 12

h = 9

V = (3.14)(12²)(9/3)

Square 12.

V = (3.14)(144)(9/3)

Divide 9 by 3.

V = (3.14)(144)(3)

Multiply 3.14 and 144.

V = (452.16)(3)

Multiply 452.16 and 3.

V = 1356.48

Round to the nearest tenth.

V = 1356.5.

Step-by-step explanation:

Answer:

27/50

Step-by-step explanation:

54 is another way of writing 54 hundredths, or as a fraction, 54/100. Asking for a simplified fraction is asking you to reduce the numerator and denominator by any common terms. 54 and 100 are both divisible by 2, so we get to 27/50. These have no factors in common, so 27/50 is our simplified fraction.

Answers

Answer:

Below in bold.

Step-by-step explanation:

The expression is:-

f(h) = 16(h + 5) - 4

Graph the line with slope 2 passing through the point (-1, -3).

Answers

Answer:

Step-by-step explanation:

Start with the standard equation of a straight line, y=mx+b, where m is the slope and b is the y-intercept (the value of y when x=0).

We know m, so:

y = 2x + b

Now find b by using the given point (-1,-3)

y = 2x + b

-3 = 2(-1) + b

b = -1

The equation is y=2x-1

The graph below represents the linear equation y = 3/5 x- 2.​

Satchmo bought half pound of mangoes for $6 how much would he pay for 13/4 pounds of mangoes ?

Answers

Answer: 39

Step-by-step explanation: 1/2   = 6

                                             13/4 = x

cross mutiply13/4 * 6=19.5divide both sides by 1/2answer is 39

If Satchmo bought half pound of mangoes for $6 then he pay $39 for 13/4 pounds of mangoes.

What is Ratio?

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Given that Satchmo bought half pound of mangoes for $6

We need to find the amount he has to pay for 13/4 pounds of mangoes.

Let x be the  amount he has to pay for 13/4 pounds of mangoes..

We find the value of x by forming a proportional equation by given data.

1/2/6=13/4/x

1/12=13/4x

Apply cross multiplication

4x/12=13

x/3=13

x=39

Hence, Satchmo pay $39 for  13/4 pounds of mangoes.
