Somebody please help me!!!
Answer:
x=19 degrees
Step-by-step explanation:
We know that the two angles add up to 180 degrees because they are supplementary and make up a straight angle. Therefore we can write and solve an equation where the sum is 180:
4x-11+20+5x=180
9x+9=180
9x=171
x=19 degrees
If m∠1 = 52°, what is m∠7?
Answer:
it would be 52 degrees as well because it is a corresponding angle
Answer:
1 and 7 are corresponding angles, meaning that they share the same angle value. So, since m<1 is equal to 52 degrees, we know that m<7 is also equal to 52 degrees.

106 square feet
ΔLMO below is similar to ΔPNO. If LO = 18 ft, PO = 9 ft, and PN = 5 ft, what is the length of LM?
What is the scale factor of ΔOMO to ΔPNO?
Answer:
The length of LM is 10, and the scale factor is 2, if not 2 then 1/2.
Step-by-step explanation:
9 is half of 18, so the ratio of LO to PO would be 18/9 this is equal to 2.
Please please please help, I give brainliest to first answer(not random nonsense)A pool is in the shape of a right rectangular prism and has a volume of 92 feet. The area of the base of the pool is 32 square feet.
create an expression to find the height, in feet, of the water in the pool
Answer:
92/32
Step-by-step explanation:
Since the formula for volume is length x width x height, and the formula for area is length x width, an expression you could use is 92/32. This divides the volume by the area, which may help find the height.
Not very confident about this answer, but I hope this helps?

The point (0.25, 1) shows the cost is $0.25 for 1 pound of cheese.
The point (0.5, 2) shows that 0.5 pound of cheese costs $2.00
The point (1,4) shows the cost is $4.00 for 1 pound of cheese.
The point (2,8) shows that 8 pounds of cheese cost $2.00.
What value of w makes this multiplication sentence true? 28 · (824 + 514) = 28 · 824 + 28 · w
w =
Answer:
514
Step-by-step explanation:
First, we need to find the value of the non-variable side.
824+514 =1,338.
1,338 multiplied by 28 is 37,464.
So now we have : 37, 464 = 28* 824 + 28* w
28* 824 is 23,072.
And then we have, 23,072 * 28w.
Subtract 37,464 by 23,072on both sides, which is equal to 14,392 = 28w
Finally, divide 14,392 by 28 on both sides to get 514 = w
Therefore, w is 514.
Good luck mate, hope this helps.
Answer:514
Step-by-step explanation:
1338 x 28 = 37464
28 x 824 = 23072
37464 - 23072 = 14392
28 x 514 = 14392

Dana and Monique are dog groomers. Dana's workday is 10 hours and Monique's workday is 8 hours. Dana and Monique each work 40 hours per week. On Monday, Dana groomed 15 dogs in 10 hours and Monique groomed 10 dogs in 8 hours. They each earn $12.75 for each dog groomed. Assuming that for the rest of the week Dana and Monique groom the same number of dogs per workday as they did on Monday, what will be the difference between their weekly earnings?
Show your work.
I need this ASAP
Answer:
$127.50
Step-by-step explanation:
On Monday Dana earned: 15*12.75 in 10 hours
For 40 hours Dana will earn: 15*12.75*(40/10) = $765
On Monday Monique earned: 10*12.75
For 40 hours Monique will earn: 10*12.75*(40/8) = $637.50
The difference between the weekly earnings is: $765 - $637.50 = $127.50.

The question is: Find the interest rate on a $895 dollar investment with $716 in interest over 5 years. Show your work.
Answer: The interest rate on the $895 investment is approximately 16%.
Step-by-step explanation:
To find the interest rate, we can use the formula for simple interest:
Interest = Principal × Rate × Time
Given:
Principal (initial investment) = $895
Interest earned = $716
Time period = 5 years
We rearrange the formula to solve for the rate:
Rate = Interest / (Principal × Time)
Substituting the given values:
Rate = $716 / ($895 × 5)
Now, let's calculate the values:
Rate = $716 / $4475
Rate ≈ 0.1599
To convert the decimal to a percentage, we multiply by 100:
Rate ≈ 0.1599 × 100
Rate ≈ 15.99%
Therefore, the interest rate on the $895 investment is approximately 15.99% or rounded to 16%.
This means that for the $895 investment, an annual interest of $716 has been earned over a period of 5 years. It indicates that the investment has grown by an average of 16% per year.

List the following parabolas from widest to narrowest (would like a fast answer)
Answer:
Step-by-step explanation:
The greater the magnitude of the leading coefficient, the narrower the parabola.
Widest: f(x) = 0.5x²
Next: f(x) = -x²
Next: f(x) = 2x²
Narrowest: 3x²
(largest to smallest)
1. f(x)= 0.5x^2
2. f(x)= -x^2
3. f(x)= -2x^2
4. f(x)= 3x^2
