Answers
Answer
the space would unknow between each side of the rug and the wall
Step-by-step explanation:
because we don't know how big the room is and what the shape of the room is we have no idea what the answer will be it could be a little less than the distance around the world or it could be no distance cause it is the same size as the room

NEED HELP ASAP NO FALSE ANSWERES. Part B: Scarlett made a profit of $250.00 with her mobile car wash company. She charged $75.00 per car wash and received $35.00 in tips, but also had to pay $5.00 in
cleaning supplies per car wash. Write an equation to represent this situation
Answers
Answer:
y = 70x + 35
Step-by-step explanation:
$75 - $5 = $70 (this is the amount charged minus the amount needed to get the job done per car wash)
the +35 is the tips extra/ constant that will be added after the jobs are done.
x is the amount of car washes done
y would be the profit received.
thus y = 70x + 35 (profit = value of car wash * number of cars washed + tips)
Answer:
Step-by-step explanation:
Profit = Income less outgo
= (car wash income + tips) - (supplies)
$250 = ($75n + $35) - ($5n), or
$215 = $70n (where n represents the number of cars washed)
This comes out to n = $215/$70, or approximately 3 car washes.

d = -10/7 = -1 3/7
that is the answer for number 1.
For number 2. the answer is U = 13/4 = 3 1/4 = 3.25
step by step explanation
multiply both sides of the equation by 4 the least common multiple of 2,4
2 (5 x 2 + 1) -4 u = 9 then multiply 5 and 2 to get 10
2 (10 + 1) -4u =9
then add 10 and one to get 11
2 x 11 -4u =9
then multiply two and 11 to get 22
22 -4u = 9
then subtract 22 from both sides
subtract 22 - 9 to get -13
-4u = -13 then undo multiplication by dividing both sides divide both sides by 4-13 / -4 can be divided by positive 13/4
your answer is 13/4

Show your work and write an expression using the following criteria:
A dividend is greater than 1,000
The quotient is 52 with a remainder of 18
please help me, fast!
Answers
Dividend (D) > 1,000
Quotient = 52
Remainder = 18
Based on these criteria, we can set up the equation as follows:
D = Quotient × Divisor + Remainder
Since the quotient is 52 and the remainder is 18, the equation becomes:
D = 52 × Divisor + 18
To meet the criteria that the dividend is greater than 1,000, we need to find a suitable value for the divisor. We can do that by rearranging the equation:
D - 18 = 52 × Divisor
Now, let's choose a value for D that is greater than 1,000. For example, let's use D = 1,500:
1,500 - 18 = 52 × Divisor
1,482 = 52 × Divisor
Dividing both sides by 52:
Divisor = 1,482 / 52
Simplifying:
Divisor ≈ 28.5
Therefore, the expression that satisfies the given criteria is:
Dividend (D) = 1,500
Quotient = 52
Remainder = 18
Divisor ≈ 28.5
The equation becomes:
1,500 = 52 × 28.5 + 18

The circumference of the scaled copy is twice the circumference of the original circle.
The area of the scaled copy is four times the area of the original circle.
How to draw a scaled copy of the circle using a scale factor of 2?
a. To draw a scaled copy of the circle with a scale factor of 2, multiply the radius of the original circle by 2, and then draw a circle with this new radius centered at the same point as the original circle.
For example, if the original circle has a radius of 4 units, the scaled copy will have a radius of 2 × 4 = 8 units.
b. The circumference of a circle is given by the formula C = 2πr,
where C is the circumference and r is the radius of the circle.
Thus, the circumference of the original circle is C₁ = 2πr₁ and the circumference of the scaled copy is C₂ = 2πr₂.
Since the scale factor is 2, we have r₂ = 2r₁, so the circumference of the scaled copy is C₂ = 2π(2r₁) = 4πr₁ = 2C₁.
This means that the circumference of the scaled copy is twice the circumference of the original circle.
c. The area of a circle is given by the formula A = πr²,
where A is the area and r is the radius of the circle.
Therefore, the area of the original circle is A₁ = πr₁² and the area of the scaled copy is A = πr₂²
Since the scale factor is 2, we have r₂ = 2r₁, so the area of the scaled copy is A₂ = π(2r₁)² = 4πr₁ ² = 4A₁ . This means that the area of the scaled copy is four times the area of the original circle.

Answer: 5x + 16
Step-by-step explanation: distribute, add the numbers, and combine like terms.
Answer:
x = -3.2
Step-by-step explanation:
First, solve parenthesis:
2(x+6)+3x+4= 0 (Given)
2x + 12 + 3x + 4 = 0 (distributive property of equality)
Then, you comibine like terms:
2x + 12 + 3x + 4 = 0
5x + 16 = 0 (Combining like terms)
And then, move the variables to the left and constants to the right:
5x + 16 = 0
5x = -16 (Subtraction property of equality) You subtract 16 from both side, since the variable is on the right already you leave it that way.
Finally, you divide both sides to get the answer ( solve for X):
5x = -16
x = -3.2 (division property of equality)
There is your answer!

A plane traveled 756 miles each way to Baltimore and back. The trip there was with the wind. It took 7 hours. The trip back was into the wind. The trip back took 9 hours. What is the speed of the plane in still air? What is the speed of the wind?
Answers
Answer:
The speed of the wind is 12 miles per hour.
Explanation:
Let's call the speed of the plane in still air "p" and the speed of the wind "w".
From the given information, we know that:
756 miles = 7 hours * (p + w) (with the wind)
756 miles = 9 hours * (p - w) (against the wind)
We can simplify these two equations by dividing both sides by 7 and 9, respectively:
108 miles/hour = p + w
84 miles/hour = p - w
Now we can use a system of equations to solve for p and w:
p + w = 108
p - w = 84
Adding these two equations, we get:
2p = 192
Dividing by 2, we get:
p = 96
So the speed of the plane in still air is 96 miles per hour.
To find the speed of the wind, we can substitute p = 96 into either of the simplified equations:
p + w = 108
96 + w = 108
Subtracting 96 from both sides, we get:
w = 12
So the speed of the wind is 12 miles per hour.
Therefore, the speed of the plane in still air is 96 miles per hour and the speed of the wind is 12 miles per hour.
Is this correct? If not, please correct it, and show all work including why it’s wrong.

Answers
Answer: Choice A is correct
Explanation:
The LCM of the coefficients 14 and 16 is 112 because (14*16)/2 = 112. We multiply the values and divide by the GCF 2.
The 'a' terms are \(a^5\) and \(a^3\). We pick the one with the largest exponent when forming the LCM. Go for the smallest exponent when finding the GCF. Similar situations occur with the b and c terms as well.
So that's how we end up with \(112a^5b^4c^2\) as the LCM.
Side note: Choice D is the GCF of the two given expressions.
