The front profile of a shed is depicted in the drawing, with the given dimensions. Find the area of this profile of the shed in square feet.

Answers

Answer:

135 ft²

Step-by-step explanation:

The profile is composed of a triangle and a rectangle.

Area of profile = (area of triangle) + (area of rectangle)

= (½×base×height) + (length × width)

Where,

base of triangle = 15 ft

height of triangle = 11 - 7 = 4 ft

length of rectangle = 15 ft

width of rectangle = 7 ft

Plug in the values

Area of profile = = (½×15×4) + (15×7)

= 30 + 105

Area of profile = 135 ft²

An albatross is a large bird that can fly 400 kilometers in 8 hours at a constant speed. Using d for distance in kilometers and t for number of hours, an equation that represents this situation is d=50t. What are two constants of proportionality for the relationship between distance in kilometers and number of hours? 50 1/50

Answers

Answer:

50

Step-by-step explanation:

Speed is represented according to the equation;

Speed = Distance/Time

Given;

Distance d = 400km

Time t = 8 hours

From the formula

s = d/t

s = 400/8

s = 50

Substitute s = 50 back into the formula;

s = d/t

50 = d/t

d = 50t

This expression means that the speed is directly proportional to t where 50 is the constant of proportionality;

Hence the constant of proportionality for the relationship between distance in kilometers and number of hours is 50

Answer: Two constants of proportionality for this situation are 50 and 1/50. The relationship between these two values are that they are both reciprocals.

A store sells bottles of water for $1.50 each. During the first hour the store was open, x bottles of water were sold. During the
second hour, the store sold 3 fewer bottles of water than it sold during the first hour. During the third hour, it sold three times as
many bottles of water as it sold during the second hour. The store was paid a total of $117.00 for bottles of water sold during these
three hours. The equation shown below represents these sales.
1.5x + 1.5(x - 3) + 1.5.3(x - 3) = 117

A bug was sitting on the tip of the propeller blade 4 ft. Long when the propeller started to rotate. The bug held on for 3 rotations before flying away. How far did the bug travel before it flew away?

Answers

Answer:

75.39 ft

Step-by-step explanation:

r = Radius of the circle drawn by the propeller = 4 ft

Circumference of the circle is

[tex]C=2\pi r\\\Rightarrow C=2\pi 4\\\Rightarrow C=25.13\ \text{ft}[/tex]

So in one rotation the distance traveled by an ant sitting on the blade tip is 25.13 ft.

Now the ant held on for 3 rotations so distance traveled is

[tex]3\times 25.13=75.39\ \text{ft}[/tex]

The bug traveled 75.39 ft.

Answers

One a piece of paper, graph f(x)= (0.4)^x. To determine which answer choice matches the graph you drew.

Answer: Graph B

The graph of a function f(x) = 6(0.4)× is shown in graph (B) because the domain of the function is all real numbers and the range of a function is f(x) > 0, the y-intercept of the function is (0, 6)

What is a function?

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a function:

f(x) = 6(0.4)×

The domain of the function is all real numbers.

The range of the function:

f(x) > 0

Plug x = 0

y = 6

Thus, the graph of a function f(x) = 6(0.4)× is shown in graph (B) because the domain of the function is all real numbers and the range of a function is f(x) > 0, the y-intercept of the function is (0, 6)

Abigail's family is buying a small refrigerator for their game room in the shape of a right rectangular prism. The inside measurements are 18 in., 14 in., and 24 in.

Answers

Answer:

Volume = 6048 [tex]in^{3}[/tex]

Step-by-step explanation:

Volume is the capacity of substance that a given measuring object can contain. It can be determined as;

Volume = length x width x height

In the given question, the refrigerator has an internal dimensions 18 inches, 14 inches and 24 inches.

The volume of the refrigerator can be determined as;

Volume = 24 x 14 x 18

            = 6048

Volume  = 6048 [tex]in^{3}[/tex]

Thus, the internal volume of the refrigerator is 6048 cubic inches.

Answers

Answer:

-3

Step-by-step explanation:

Let the unknown number be n

We are to write the expression as equation;

Six times a number plus 4 is the same as the number minus 11.

Six times a number is given as;

6n

Six times a number plus 4 is expressed as 6n+4

The unknown number minus 11 will be expressed as n-11

Finally If Six times a number plus 4 is the same as the number minus 11, them!

6n+4 = n-11

Next is to calculate n;

Collect like terms;

6n-n = -11-4

5n =-15

Divide through by5

5n/5 = -15/5

n = -3

Hence the vale n is -3

The first equation of the system is multiplied by 2. By what number would you multiply the second
equation to eliminate the y variable by adding?
4x – 3y = 6
6x + 2y = 10

Answers

Answer:

we will have to multiply the second equation by 3 to eliminate the y variable by adding.

Step-by-step explanation:

Given the equations

4x – 3y = 6              →   (1)

6x + 2y = 10             →   (2)

As the first equation is multiplied by 2,

2(4x – 3y) = (2)6

8x - 6y = 12               →  (3)

As we have to eliminate y,

so multiply the second equation by 3,

6x + 2y = 10

3(6x + 2y) = 3(10)

18x + 6y = 30              →  (4)

So now adding the new equations (3) and (4) will eliminate the y variable by adding

8x - 6y = 12

18x + 6y = 30

--------------------

26x + 0y = 42

26x = 42

x = 42/26

x = 21/13

Therefore, we will have to multiply the second equation by 3 to eliminate the y variable by adding.
