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:

32.5 feet

Step-by-step explanation:

This situation forms a right triangle. We are given the distance from the base of the tower (long leg of the triangle) and are asked to find the height (short leg of the triangle).

With this information, we can use the tan ratio, opposite over adjacent, to find the height of the tower.

tan 18 = [tex]\frac{x}{100}[/tex]

Multiply each side by 100:

(100) tan 18 = x

Simplify and round to the nearest tenth:

32.49 = x

32.5 = x

So, the height of the tower is approximately 32.5 feet

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

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:

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

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.

Answer:

your answer will be C. The function has an inverse because it passes the horizontal line test.

bye have a nice day ^_^

C. The function has an inverse because it passes the horizontal line test.

A function is a rule or a relation that associates each element of a non-empty set A, to at least a single element of another non-empty set B.

The relation f from a domain set to co-domain set is called function.

Example : f = {(x, y) | for all x∈X & y∈Y}

A relation becomes function when every element of domain has one and only one image in co-domain.

If f is a function which is one-one as well as on-to, i.e, if the function is bijective, then the inverse of this function exists and the inverse is then denoted by [tex]f^{-1\\}[/tex]

Inverse function of a function always undoes the operations of the function f.

f(a) = b if and only if f⁻¹ (b) = a , where a is from domain & b is from co-domain set.

From the above descriptions, we can see that, since the function passes through the horizontal line, so it has an inverse.

Hence the option C is the correct one.

C. The function has an inverse because it passes the horizontal line test.

Step-by-step explanation:

The cost of 7kg of brass is £32.48.

A ratio is a comparison of two or more numbers that indicates their sizes in relation to each other.

According  to the given question.

Cost of one kg of copper = £5

Cost of one kg of zinc = £3.20

Also, copper and zinc are mixed in the ratio 4:1.

Let the quantity of copper be 4x and the quantity of  zinc 1x.

Weight of brass = 7kg

⇒ 4x + 1x = 7

⇒ 5x = 7

⇒ x = [tex]\frac{7}{5}[/tex]

⇒ x = 1.4

Weight of copper, 4x = (1.4)(4) = 5.6kg

Weight of zinc, 1x = (1) ×(1.4)  = 1.4kg

Therefore,

The cost of 7kg of brass

= (5.6)×(£5) + (1.4)(£3.20)

= 28 + 4.48

= £ 32.48

Therefore, the cost of 7kg of brass is £32.48

Renters do not have the maintenance costs associated with home ownership. Therefore, option B is the correct answer.

In mathematics, the tax calculation is related to the selling price and income of taxpayers. It is a charge imposed by the government on the citizens for the collection of funds for public welfare and expenditure activities. There are two types of taxes: direct tax and indirect tax.

Both renting and buying have their financial advantages, and owning a home isn’t right for everyone.

Unlike homeowners, renters have no maintenance costs or repair bills and they don't have to pay property taxes.

Amenities that are generally free for renters aren't for homeowners, who have to pay for installation and maintenance.

Renters do not have the maintenance costs associated with home ownership.

Home owners have to pay for all costs & repairs needed.

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.
