Answer:
39
Step-by-step explanation:
In words, Elise's statement can be expressed as follows:
(x-13)(-7) = -182
where x is the number. Working it out you get:
x-13 = 26
x=39
Answer:
39
Step-by-step explanation:
let's use 26 as x
26-13=13*-7=-182
-182 /-7= 26
26+13=39
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
How much money was the store paid for bottles of water sold during the second hour it was open?
(A) $15.00
(B) $22.50
(C) $27.00
(D) $67.50
Answer: 22.50$
Step-by-step explanation:
1.5x+1.5(x-3)+1.5*3(x-3)=117
1.5x+1.5x-4.5+1.5(3x-9)=117
3x-4.5+4.5x-13.5=117
7.5x-18=117
7.5x=135
x=135/7.5
x=18
hour 2
1.5(18-3)=
1.5*15= 22.5$
Answer:
The answer is $22.50

KN = 18
Step-by-step explanation:
I really don't know how to explain it .
Answer: since KM is the long line, and KN is half of that since the line is half the size of KM, half of KM is 18.
So KN=18
how do you find whether a pair of lines are parallel, perpendicular?
Answer:
If two lines are parallel they have the same slope, if they are perpendicular they have opposite slopes.
Step-by-step explanation:
Example of parallel lines: y=3x+10 & y=3x-4
Example of perpendicular lines: y=2x-9 & y=-1/2x+1

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?
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.

On a piece of paper, graph f(x) = 6× (0.4)^x Then determine which answer choice matches the graph you drew.
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)

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
Answer:
50Step-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.

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.
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

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.
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.

Word Study Directions: Read the question. Then choose the best answer. Which word contains an open first syllable? A. connect B. frozen C. problem D. traffic
Answer:
B. frozen
Step-by-step explanation:
An open first syllable is one that has a vowel at its end and that vowel causes a long vowel sound at its end. Long vowel sounds are those sounds whose pronunciation is the same as those of the letters.
Among the words listed, fro-zen has a long vowel sound in the form of the o at the end of the first syllable. Thus it can be classified as having an open first syllable.
