Volume = lwh (we are already told the volume, length, and width, so we can rearrange the formula to find height)

l=V/wh
= 270/15(9)
=270/135
=2 m

This means the height of the pool is 2m, hope this helps!! :)

It gets 2m because with the formula lxwxh you can get the amount of the height

Explain which variables would be included when using technology to calculate the present value of a lump sum and to calculate th
koban [17]

Answer:

a. Present value of a lump sum =

PV = FV / ( 1 + i )ⁿ

b. Present value of an annuity =

P = PMT x ((1 – (1 / (1 + r)⁻ⁿ )) / r)

Step-by-step explanation:

a. Present Value of a Lump sum =

PV = FV / ( 1 + i )ⁿ

Where variables in the formula are explained as follows

PV = Present Value of the given amount today

FV = Future Value of the given amount

i = Discount rate

n = Number of periods

b. Present value of an annuity is given as:

P = PMT x ((1 – (1 / (1 + r)⁻ⁿ)) / r)

The variables in the equation are explained as the follows:

P = the present value of annuity

PMT = Payment per period or the amount in each annuity payment

r =  the interest or discount rate

n = total number of periods or the number of payments left to receive

0.12x - 1.5= 0.24x - 0.06
Sophie [7]

To solve this equation, lets move all of the variables to one side of the equation and the constants to the other.

0.12x - 1.5 = 0.24x - 0.06

Subtract 0.12x from both sides of the equation

-1.5 = 0.12x - 0.06

Add 0.06 to both sides of the equation

-1.44 = 0.12x

Divide both sides by 0.12 to isolate x

x = -12

Two similiar rectangles have corresponding sides in the ratio 10:3. What is the ratio of their areas
lianna [129]

Answer:

Step-by-step explanation:

The ratio of its areas is equal to

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

In this problem the scale factor is equal to the ratio 10:3

Let

z-------> the scale factor

so

z2=(10/3)2=100/9

How do i find the missing base of a trapezoid?
11111nata11111 [884]
The tops and bottoms of a trapezoid are parallel, and a polygon's volume and angles are always 360.As long as you know the shape and about three of the lengths, you can find the base.

Tasha can spend more than $40 on new boots. Write and graph an inequality to describe how much she can spend.
Svetllana [295]

Answer:

x> \$40

The graph in the attached figure

Step-by-step explanation:

Let

x-----> money that Tasha can spend on new boots

we know that

The inequality that represent the situation is equal to

x> \$40

The solution is the interval--------> (40,∞)

All real numbers greater than 40

In a number line the solution is the shaded area to the right of the dashed line at 40 (open circle)

see the attached figure
