Laundry detergent comes in 2 sizes. Box A is $7.62 for 2.5 Litres, Box B is
$5.74 for 1.5 Litres. Which is the better deal and by how much?

Answers

Answer:

$7.25 = 2.5, so divide by 7.25 by 5 = 1.45 <- better deal & $0.46333333333 per litre.

5.74 = 1.5, so divide 5.74 by 3 = 1.91333333333

Step-by-step explanation:

Why 3 and 5 - 0.5 is 5 times 2.5 and so is 0.5 times 3= 1.5

1.91333333333 - 1.45 = $0.46333333333 per litre.

Your backyard is 27 feet longer than it is wide. Its area is 9718 square feet. What is the width Set up and solve a quadratic equation.

Answers

Answer:

Width = 86 feet

Step-by-step explanation:

Create two equations with the info:

L = 27 + W

where L represents the length and W the width of the backyard.

The other one is about the area of the rectangular backyard:

Area = L x W

where you replace the area with 9718 and the length (L) with (27 + W):

[tex]Area= L\,*\,W\\9718=(W+27)\,W\\9718=W^2+27\,W\\W^2+27\,W-9718=0[/tex]

and solve for W using the quadratic equation:

[tex]W=\frac{-27+/-\sqrt{27^2-4(1)(-9718)} }{2\,(1)} \\W=\frac{-27+/-\sqrt{39601}}{2} \\W=\frac{-27+/- 199}{2}[/tex]

This gives us two solutions:

W = - 113

and W = 86

We use the positive solution since this is a distance.

Therefore the width is: 86 feet

Answers

Answer:

62

Step-by-step explanation:

Plug in the value of a in the equation:

12(4) - 6 + 7(4) - 2(4)

Solve 12(4) - 6:

12(4) - 6 = 48 - 6 = 42

Solve 7(4) - 2(4):

7(4) - 2(4) = 28 - 8 = 20

Combine both answers (42+20):

42+20 = 62

Complete answer:

12(4) - 6 + 7(4) - 2(4) = 62

The perimeter of a rectangular movie screen at a local cinema is 148 feet. If the length of the screen is 30 feet longer than the width, what is the length of the screen, in feet?

Answers

The perimeter of a rectangle = 2(l + w)

l = length

w = width

In this problem,

w = x

l = x + 30

the perimeter = 148

Let's plug our values into the perimeter formula above.

148ft = 2(x + x + 30ft)

Combine like terms.

148ft = 2(2x + 30ft)

Distribute the 2

148ft = 4x + 60

Subtract 60 from both sides

88ft = 4x

Divide both sides by 4

22ft = x

The width = x = 22ft

The length = x + 30 = 22 + 30 = 52ft

How many gallons of paint are needed to paint the walls of a rectangular prism shaped room that is 20 ft by 13 ft and 8 ft high if 1 gallon of paint covers 40 square feet?

Answers

Answer:

20 Gallons of paint are needed.

Step-by-step explanation:

Surface Area of a rectangular prism formula is 2 * length * width + 2 * length * height + 2 * width * height.

Substituting the given values, we get:

SA = 2 * 20 * 13 + 2 * 20 * 8 + 2 * 13 * 8

SA = 1048

Area of the floor is length * width. 20 * 13 = 260

Subtract the area of the floor from SA as we do not paint the floor. 1048 - 260 = 788

The number of gallons of paint is 788 / 40 as each gallon covers 40 sq feet. We round this number up to ensure that we have more than enough paint. 788 / 40 = 19.7. Rounding that to 20.

Therefore, 20 gallons of paint are needed.

The width of a rectangle is 1/2 of its length. What are the sides of the rectangle if its perimeter is 63 in.? pls help asap i will award brainliest

Answers

Answer:

[tex] \boxed{ \sf{length \: of \: a \: rectangle = 21 \: in.}}[/tex]

[tex] \boxed{ \sf{width \: of \: a \: rectangle = 10.5 \: in.}}[/tex]

Step-by-step explanation:

Let the length of a rectangle be ' l '

Width of a rectangle ( w ) = [tex] \sf{ \frac{1}{2} l}[/tex]

Perimeter of a rectangle ( P ) = 63 in.

First, finding the length of a rectangle ( l )

[tex] \boxed{ \sf{perimeter \: of \: a \: rectangle = 2(l + b)}} \:[/tex]

[tex] \dashrightarrow{ \sf{63 = 2(l + \frac{1}{2} l}})[/tex]

Distribute 2 through the parentheses

[tex] \dashrightarrow{ \sf{63 = 2l + 2 \times \frac{1}{2} l}}[/tex]

[tex] \dashrightarrow{ \sf{63 = 2l + l}}[/tex]

Add the like terms : 2l and 3l

[tex] \dashrightarrow{ \sf{63 = 3l}}[/tex]

Swap the sides of the equation

[tex] \dashrightarrow {\sf{3l = 63}}[/tex]

Divide both sides by 3

[tex] \dashrightarrow{ \sf{ \frac{3l}{3} = \frac{63}{3}}} [/tex]

Calculate

[tex] \dashrightarrow{ \sf{l = 21 \: in.}}[/tex]

Length of a rectangle = 21 in.

Now, replacing / substituting the value of l in 1/2 l in order to find the width of a rectangle

[tex] \dashrightarrow{ \sf{width = \frac{1}{2} l}}[/tex]

[tex] \dashrightarrow{ \sf{width = \frac{1}{2} \times 21}}[/tex]

[tex] \dashrightarrow{ \sf{width = 10.5 \: in.}}[/tex]

Width of a rectangle = 10.5 in.

What’s the slope of (6, 12) and (-6,-2)

Answers

Answer:

m= 7 / 6

Step-by-step explanation:

we need to start out by plugging in the integers into the formula which is the following:

m= y2 - y1 / x2 - x1

m= -2 - 12 / -6 - 6

then we begin to solve

m= -14 / -12

this is not in its simplest form, so we simplify it

(in this case I simplified by 2)

m= -7 / -6

and because two negatives will give you a positive, your final answer is

m= 7 / 6

These triangles are scaled copies of each other.

For each pair of triangles listed, the area of the second triangle is how many times larger than the area of the first?

Answers

Answer/Step-by-step explanation:

Recall: the ratio of the areas of two similar figures = the square of the ratio of the corresponding sides of the similar figures.

This will give us the scale factor.

The scale factor indicates how many times larger the second triangle is than the area of the first.

Let's find how many times larger is the area of the second triangle is to the first:

1. ∆ G And ∆ F

[tex] \frac{Area_{F}}{Area_{G}} = \frac{side_{F}^2}{side_{G}^2} [/tex]

[tex] \frac{Area_{F}}{Area_{G}} = \frac{6^2}{3^2} [/tex]

[tex] = \frac{36}{9} = 4 [/tex]

∆F is 4 times larger than ∆G

2. ∆ G And ∆ B

[tex] \frac{Area_{B}}{Area_{G}} = \frac{side_{B}^2}{side_{G}^2} [/tex]

[tex] \frac{Area_{B}}{Area_{G}} = \frac{2^2}{4^2} [/tex]

[tex] = \frac{4}{16} = 0.25 [/tex]

∆B is 0.25 times ∆G

3. ∆ B And ∆ F

[tex] \frac{Area_{G}}{Area_{B}} = \frac{side_{F}^2}{side_{B}^2} [/tex]

[tex] \frac{Area_{F}}{Area_{B}} = \frac{8^2}{2^2} [/tex]

[tex] = \frac{64}{4} = 4 [/tex]

∆F is 16 times larger than ∆B

4. ∆ F And ∆ H

[tex] \frac{Area_{H}}{Area_{F}} = \frac{side_{H}^2}{side_{F}^2}} [/tex]

[tex] \frac{Area_{H}}{Area_{F}} = \frac{2^2}{6^2} [/tex]

[tex] = \frac{4}{36} = \frac{1}{9} [/tex]

∆H is ⅑ times ∆F

5. ∆ G And ∆ H

[tex] \frac{Area_{H}}{Area_{G}} = \frac{side_{H}^2}{side_{G}^2} [/tex]

[tex] \frac{Area_{H}}{Area_{G}} = \frac{2^2}{3^2} [/tex]

[tex] = \frac{4}{9} [/tex]

∆G is 4/9 times ∆G

6. ∆ H And ∆ B

[tex] \frac{Area_{B}}{Area_{H}} = \frac{side_{B}^2}{side_{H}^2} [/tex]

[tex] \frac{Area_{B}}{Area_{H}} = \frac{1.5^2}{2^2} [/tex]

[tex] = \frac{2.25}{4} = 0.6 [/tex] (nearest tenth)

∆B is 0.6 times ∆H

Step-by-step explanation:

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

The number of hours required to tutor to have enough money to pay for the trip is 23 hours.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Number of days for the summer vacation = 6

Savings = $840

Earnings per hour = $45

Airfare cost = $525

Food and sightseeing = $780

Hotel cost per night = $95

Number of hours = x

We can make an expression.

525 + 780 + 6 x 95 = 840 + 95x

525 + 780 + 570 = 840 + 45x

1875 = 840 + 45x

1875 - 840 = 45x

1035 = 45x

1035/45 = x

x = 23

This means 23 hours.

Thus,

The number of hours required to tutor to have enough money to pay for the trip is 23 hours.
