Tariq also designs hot tubs. The diameter of the hot tub is 3 meters. What is the area of the deck that surrounds the hot tub? I

lutik1710 [3]

Answer:

C. 17.9

Step-by-step explanation:

First you have to find the area of the circle, to then subtract it from the area of the square around it.

To get the area of the circle you must take the radius(half of the diameter) and square it. 3^2 is 9. Then you mutiply that by Pi( 3.14). Which is 7.07.

Next you have to subtract that from the area of the square deck.

25-7.07=17.9

Drag each expression to show whether it can be used to find the surface area, volume or neither

Brut [27]

Answer:

Surface area:

$2(12\times 6) + 2(6 \times 8) + 2(8 \times 12)$

$2((12\times 6) + (6 \times 8) + (8 \times 12)$

Volume :

$(12 \times 6 \times 8)$

Neither:

$8(12 \times 6)$

$2(12 \times 6 \times 8)$

$12+6+8$

Step-by-step explanation:

Surface area of the cuboid:

The Surface area of the cuboid = 2(lb) +2(bh) +2(hl)

Where

l =length of the cuboid

b = Breadth of the cuboid

h = height of the cuboid

So ,

The surface area will be

SA = $2(12\times 6) + 2(6 \times 8) + 2(8 \times 12)$

SA = $2((12\times 6) + (6 \times 8) + (8 \times 12))$

SA = $2(72+48+98)$

SA = $2(216)$

SA = 432

Volumes of the cuboid:

$Volume = length \times breadth \times height$

Volume = $(12 \times 6 \times 8)$

volume = 576

The conversion of square feet to square yards can be represented by direct variation. Three square yards are

grandymaker [24]

<h3>The constant of variation is $\frac{1}{9}$ </h3><h3>The equation is $y=\frac{1}{9}x$ </h3>

<em><u>Solution:</u></em>

Given that,

The conversion of square feet to square yards can be represented by direct variation

Let y represent the number of square yards

Let x be the number of square feet

$y \propto x$

y = kx ------ eqn 1

Where, "k" is the constant of variation

Three square yards are equivalent to 27 square feet

Substitute, y = 3 and x = 27 in eqn 1

$3 = k \times 27\\\\k = \frac{3}{27}\\\\k = \frac{1}{9}$

Thus the constant of variation is $\frac{1}{9}$

<em><u>What is the equation representing the direct variation?</u></em>

Substitute k = 1/9 in eqn 1

$y = \frac{1}{9}x$

Thus the equation is found

Jersey village population in 1950 was 10,173. The population increases by 8.9% every 10 years. Predict the population in 2020

Oksanka [162]

Answer:

Future Value= 18,478 people

Step-by-step explanation:

eGiving the following information:

Present value (PV)= 10,173

Growth rate (g)= 0.089 every 10 years

Number of periods (n)= 7

<u>To calculate the population in 2020, we need to use the following formula:</u>

FV= PV*(1 + g)^n

FV= 10,173*(1.089^7)

FV= 18,478 people
