Answer:

222 ft

Step-by-step explanation:

add 15 ft to each side of the length and width

L = 28 + 30 = 58

W = 23 + 30 = 53

perimeter = 2(L + W) = 2(58 + 53) = 222 ft

Answer:

222 ft

Step-by-step explanation:

The fence must be 15x2 (30) feet wider and 15x2 (30) feet longer, since the fence must be 15ft away at all points. Take 23+30 to find width, and take 28+30 to find length. You get that the fence is 53 ft. wide and 58 ft long. Feet of fencing is the same as asking for perimeter, so 53+53+58+58=222 feet of fencing

Answer:

Step-by-step explanation:

h and c are the numbers of hamburgers and cheeseburgers, respectively.

“a combined total of 486 hamburgers and cheeseburgers”

h + c = 486

“64 fewer cheeseburgers sold than hamburgers”

c = h - 64

Substitution:

h + (h-64) = 486

2h = 550

h = 275

275 hamburgers were sold

Answer:

The answer is [tex]7\frac{1}{4}[/tex]

Step-by-step explanation:

Divide the numerator by the denominator.

Write down the whole number result.

Use the remainder as the new numerator over the denominator. This is the fraction part of the mixed number.

This is what it would look like.

29÷4 is 7.25

then you would use the 7 as the whole number and what you used to get 7.25 as the numerator and denominator.

Step-by-step explanation:

Answer:

Step-by-step explanation:

L-6=W+3

L=W+9

LW-(L-6)(W+3)=27, using L from above makes this

W(W+9)-(W+9-6)(W+3)=27

W^2+9W-(W+3)(W+3)=27

W^2+9W-W^2-6W-9=27

3W-9=27

3W=36

W=12, since L=W+9

L=12+9=21

A=LW

A=21(12)

A=252 cm^2

The area of the rectangle is 252 cm^2.

Since

If the length of a rectangle is decreased by 6 cm and the width is increased by 3 cm.

So it can be like

L-6=W+3

L=W+9

Now

LW-(L-6)(W+3)=27

So,

W(W+9)-(W+9-6)(W+3)=27

W^2+9W-(W+3)(W+3)=27

W^2+9W-W^2-6W-9=27

3W-9=27

3W=36

Also,

W=12, since L=W+9

L=12+9=21

So,

A=LW

A=21(12)

A=252 cm^2

Step-by-step explanation:

Answer:

Step-by-step explanation:

root(23) - 8 < root(23) - 3      -3 is greater than -8

3 root(62) > 3 root(59)          62 > 59  Since the numbers are positive the roots of the larger number is going to be larger than the roots of the smaller number

-root(50) < - 3

The root of 50 is about 7. - 7 is smaller than - 3. Think money. Would you rather pay 3 dollars for a cup of coffee than 7 dollars for a cup of coffee?

root 15 + 2  < root(65) - 1

root(15) is roughly 4 when 2 is added to it, the result is about 6

root (65) is a touch over 8. When 1 is subtracted the result is about 7.

That's larger than the left side.

Answer: The cost to rent bowling shoes is $2.

Step-by-step explanation:

Let's define:

S = cost for renting bowling shoes.

G = cost per game.

Then if you rent shoes, and play x games, the total cost is:

C = S + x*G

We know that Sarah rented the shoes and she played 3 games, paying a total of $9.50, then:

C = $9.50 = S + 3*G

We also know that Connor rented the shoes and played 5 games, with a total cost of $14.50

C = $14.50 = S + 5*G

Then we have a system of equations.

$9.50 = S + 3*G

$14.50 = S + 5*G

To solve this, we first need to isolate one of the variables in one of the equations. I will isolate S in the first one:

S = $9.50 - 3*G

Now we can replace this on the other equation:

$14.50 = ($9.50 - 3*G) + 5*G

$14.50 - $9.50 = 5*G - 3*G

$5 = 2*G

$5/2 = G

$2.50 = G

Then each game costs $2.50

The cost to rent bowling shoes can be found with any of the two equations, for example i will use:

S = $9.50 - 3*G

Where we replace G by the value we found above.

S = $9.50 - 3*$2.50 = $2

S = $2.

The cost to rent bowling shoes is $2.

Grace needs to invest, to the nearest cent, for the value of the account to reach $46,000 in 13 years is 27705.78944.

We have given that,

Grace is going to invest in an account paying an interest rate of 3.8% compounded continuously.

We have to determine how much would Grace need to invest, to the nearest cent, for the value of the account to reach $46,000 in 13 years.

[tex]A=Pe^{rt}[/tex]

A=46000, t=13  ,r=0.038

[tex]Pe^{0.039\left(13\right)}=46000[/tex]

[tex]Pe^{0.039\left(13\right)}=46000[/tex]

[tex]\frac{Pe^{0.039\cdot \:13}}{e^{0.507}}=\frac{46000}{e^{0.507}}[/tex]

[tex]P=\frac{46000}{e^{0.507}}[/tex]

[tex]\quad P=27705.78944[/tex]

Therefore, Grace needs to invest, to the nearest cent, for the value of the account to reach $46,000 in 13 years is 27705.78944.

Volume of cuboid = 2000 m³

Step-by-step explanation:

Given the following data;

Base area = 500 m²

Height = 4m

To find the volume of a cuboid;

The volume of a cuboid is given by the formula;

Volume of cuboid = length * breadth * height

But remember, base area = length * breadth

Therefore, the volume of the cuboid becomes;

Volume of cuboid = base area * height

Substituting into the equation, we have;

Volume of cuboid = 500 * 4

Volume of cuboid = 2000 m³
