Volume=125 cu ft
Length=5 ft
Width=?___
Height=5 ft
Answer:
5 ft.
Step-by-step explanation:
First, start with a formula. To find the volume, you have to multiply the length, width, and height.
V = lwh
Plug in the variables that you already know.
125 = 5 ⋅ w ⋅ 5
Simplify.
125 = 25w
Divide both sides by 25 to isolate w.
5 = w

The function y = 12x − 40 represents the amount of money that Sam has after paying Daniel back in terms of the number of hours he works at the airport. Match the values and variables to the aspects of the situation they represent.
Answer:
Question requires options [See explanation]
Step-by-step explanation:
Given
[tex]y = 12x - 40[/tex]
Required
Interpret each value and variable of the expression
From the question, we understand that Sam owes Daniel.
A slope intercept equation is:
[tex]y = mx + b[/tex]
Where
[tex]m \to[/tex] Slope or Rate
[tex]b \to[/tex] y intercept (Value of y, when x = 0)
So, the interpretation is as follows;
[tex]40 \to[/tex] Amount Owed
[tex]12 \to[/tex] Sam's earnings per hour
x and y can be interpreted separately as:
[tex]x \to[/tex] Number of hours worked
[tex]y \to[/tex] Amount left after paying part of the debt from his earnings

At a basketball game, the manager of the arena wanted to know how many fans from the away team were in attendance. He noticed that 15 out of the first 36 people were fans of the away team. If there are a total of 360 people who attend the game, about how many people can he predict are fans of the away team?
Answer:
About 150 people.
Step-by-step explanation:
1.) 15/36 = x/360
2.) 150/360 = x/360
3.) 150/360 = 150/360
Animal shelters in a county need at least 15% of their animals to be adopted weekly to have room for the new animals that are brought into the various shelters. The county manager takes a random sample of shelters each week to estimate the overall proportion of animals that are adopted. If he concludes that the proportion has dropped below 15%, he will not accept any new animals into the shelters that week. He tests the hypotheses: H0: The adoption rate is 15%, and Ha: The adoption rate is less than 15%. What is a Type II error, and what is its consequence in this context
Answer:
By accepting a false null hypothesis he committed a type II error.
Step-by-step explanation:
Type II error is to accept H0 when H0 is false.
If there's a type II error then the null hypothesis is false ie the adoption rate is less than 15 %, when the true adoption rate is not less than 15% . He has accepted the null hypothesis as true and taken the wrong decision of not accepting any new animals into the shelters that week.
Answer:
A
The manager believes the adoption rate is still 15%, when it actually has dropped below 15%. The manager will accept more animals into the shelters and will run out of room.

There are 16 rats in a cage. The ratio of white rats to all rats is 3:4. How many white rats are in the cage?
Answer:
There are 12 white rats in the cage.
Step-by-step explanation:
3 : 4 The question says there are 16 rats in the cage. Meaning that 16 is the
x4 x4 total. Since 4(from the ratio)x4 is 16. You would multiply 4 on both sides.
12 : 16
Meaning there are 12 white rats to 16 total rats.

A rope is stretched from the top of a
7-foot tent pole to a point on the ground
12 ft from the base of the pole. How long
is the rope ?
Answer:
Step-by-step explanation:
we know two sides of a triangle, one side is 7 feet, the other is 12 feet , so use Pythagoras theorem
[tex]C^{2}[/tex] = [tex]A^{2}[/tex] + [tex]B^{2}[/tex]
[tex]C^{2}[/tex] = [tex]7^{2}[/tex] + [tex]12^{2}[/tex]
[tex]C^{2}[/tex] = 49 + 144
[tex]C^{2}[/tex] = 193
C = [tex]\sqrt{193}[/tex]
C = 13.89 feet
Answer:
The square of the hypotenuse equals the square of the sum of the other two sides.
13.89ft
Step-by-step explanation:
Definition Of Pythagoras Theorem :The Pythagorean theorem states that the total of the squares on a right triangle's legs equals the square on the hypotenuse (the side opposite the right angle)—or, in popular algebraic form, a2 + b2 = c2.
Given:Height of the Tent Pole = 7ft.
Base of the Pole of the Tent = 12ft.
Now we will use Pythagoras theorem to find how long the rope is.
Use of Pythagoras theorem
[tex]\begin{aligned}&C^{2}=A^{2}+B^{2} \\&C^{2}=7^{2}+12^{2} \\&C^{2}=49+144 \\&C^{2}=193 \\&C=\sqrt{193} \\&C=13.89 \text { feet }\end{aligned}[/tex]Hence, the length of the rope is 13.89ft.

what operation do you use to convert from a larger measurement unit to a smaller measurement unit? Explain why
Answer:
Use multiplication and dividing.
Step-by-step explanation:
If you want to convert to a smaller unit, you must multiply.
For example...
4 Feet to Inches:
[tex]4 * 12 =48[/tex] inches
2 Yards to Inches:
[tex]2 * 3 = 6[/tex] feet
[tex]6 * 12 = 72[/tex] inches
If you want to convert to a larger unit, you must divide.
336 Inches to Feet:
[tex]336/12=28[/tex] feet
756 Inches to Yards:
[tex]756/12=63[/tex] feet
[tex]63/3=21[/tex] yards
72 mi
21 mi
What is the length of the hypotenuse?
Answer:
75 mi
Step-by-step explanation:
c squared = a squared + b squared
c squared = 72 squared + 21 squared
c squared = 5184+441
c squared = 5625
c = root 5625
c = 75 mi

If the width of the TV is 40 inches, how tall is the TV? Round to the nearest tenth of an inch.
Answer:
36.3
Step-by-step explanation:
I tried using the Pythagorean Theorem to measure the length (tallness) of the TV.
[tex]a^2 + b^2 = c^2[/tex]
[tex]a^2 + (40)^2 = (54)^2[/tex]
[tex]a^2 + 1600 = 2916[/tex]
[tex]a^2 = 2916-1600 = 1316[/tex]
[tex]a = \sqrt{1316}[/tex]
[tex]a = 36.27671429[/tex]
When this is rounded up to the nearest tenth, it would go up to 36.3.
So, the length (tallness) of the TV would be 36.3 inches.

You observe the heights of two plants for an experiment. Plant A has a height of 8 centimeters and grows 1 centimeter each week. Plant B has
a height of 4 centimeters and grows 2 centimeters each week. Let x represent the number of weeks and let y represent the height of the
plant
a. Write a system of linear equations that represents this situation
System of equations:
b. Will the plants ever have the same height?
Using linear functions, it is found that:
a)
[tex]y_A(x) = 8 + x[/tex]
[tex]y_B(x) = 4 + 2x[/tex]
b) They will have the same height after 4 weeks.
A linear function has the following format:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change.b is the y-intercept, which is the value of y when x = 0.Item a:
Plant A has a height of 8 centimeters and grows 1 centimeter each week, hence:
[tex]y_A(x) = 8 + x[/tex]
Plant B has a height of 4 centimeters and grows 2 centimeters each week, hence:
[tex]y_B(x) = 4 + 2x[/tex]
The system is:
[tex]y_A(x) = 8 + x[/tex]
[tex]y_B(x) = 4 + 2x[/tex]
Item b:
Equaling the equations:
[tex]y_A(x) = y_B(x)[/tex]
[tex]8 + x = 4 + 2x[/tex]
[tex]x = 4[/tex]
They will have the same height after 4 weeks.

An advertising company charges $40 per half-page advertisement and $75 per full-page advertisement. Michael has a budget of $800 to purchase 13 advertisements. • Define a variable for each unknown. • Write a system of equations to represent the situation and solve the system
• • • How many half-page advertisements does Michael purchase? • Show your work. •
How many full-page advertisements does Michael purchase? Show your work.
Answer:
full page = 8
half page = 5
Step-by-step explanation:
two equations can be derived from the question
40x + 75y = 800 equation 1
x + y = 13 equation 2
x = number of half page advertisement
y = number of full page advertisement
multiply equation 2 by 40
40x + 40y = 520 equation 3
subtract equation 3 from 2
280 = 35y
y = 8
substitute for y in equation 2
x + 8 = 13
x = 13 - 8
x = 5
To frame two problems of linear equation in one variable of your choice and solve such that the result of the first problem should be 79 and the next problem is 25.
Answer:
[tex]x + y = 79[/tex] and
[tex]x - y = 25[/tex]
[tex](x,y) = (52,27)[/tex]
Step-by-step explanation:
Let the variables be: x and y
The equations can be modelled as:
[tex]x + y = 79[/tex] and
[tex]x - y = 25[/tex]
To solve for x and y, we have:
Make x the subject in [tex]x - y = 25[/tex]
[tex]x = 25 + y[/tex]
Substitute [tex]x = 25 + y[/tex] in [tex]x + y = 79[/tex]
[tex]25 + y + y = 79[/tex]
[tex]25 + 2y = 79[/tex]
Collect like terms
[tex]2y = 79 - 25[/tex]
[tex]2y = 54[/tex]
Divide both sides by 2
[tex]y = 27[/tex]
Substitute [tex]y = 27[/tex] in [tex]x = 25 + y[/tex]
[tex]x = 25 + 27[/tex]
[tex]x = 52[/tex]
So, we have:
[tex](x,y) = (52,27)[/tex]
