Answer:
it is B 70° because if you add 40° + 70° = 110°
so then you need to subtract that from 180°.
180° - 110° = 70°
The measure of angle x is 150 degree.
What is Supplementary Angle?The definition of "supplementary" in mathematics relates to angles that combine to form a straight angle. It indicates that when two angles sum up to 180 degrees, they are said to be supplementary angles.
As, the angle adjacent to 70° angle
= 180- 70
= 110°
Now, the angle supplement to x
x = 180 - (40+ 110)
x = 180 - 150
x = 30
So, the measure of angle x is 150 degree.

Leila made $70 for 5 hours of work.
At the same rate, how much would she make for 8 hours of work?
Answer:
112$
Step-by-step explanation:
First, find out how much she makes per hour:
70$ in 5 hours. Divide 70 by 5.
70/5 = 14
If she makes 14$ per hour, the equation to find 8 hours is 14*8

that is the formula, with r being the radius.
then if you replace r with 7 that would be the answer.
pi, also equals 3.14159265359, or shortened 3.14.
so it would look like:

Mr. Mole's burrow lies 5 55 meters below the ground. He started digging his way deeper into the ground, descending 3 33 meters each minute. Graph the relationship between Mr. Mole's elevation relative to the ground (in meters) and time (in minutes).
At the 95% confidence level, the margin of error for this survey, expressed as a proportion, is approximately 0.0288.
To calculate the margin of error for a survey expressed as a proportion, we need to use the formula:
Margin of Error = Critical Value [tex]\times[/tex] Standard Error
First, let's find the critical value.
For a 95% confidence level, we can refer to the standard normal distribution (Z-distribution) and find the z-value associated with a 95% confidence level.
The critical value for a 95% confidence level is approximately 1.96.
Next, we need to calculate the standard error.
The standard error for a proportion can be computed using the formula:
Standard Error [tex]= \sqrt{((p \times (1 - p)) / n)}[/tex]
Where:
p = proportion of respondents in favor of the plan
n = sample size
In this case, the proportion in favor of the plan is 37/185 = 0.2 (rounded to the nearest thousandth).
The sample size is 185.
Now we can calculate the standard error:
Standard Error [tex]= \sqrt{((0.2 \times (1 - 0.2)) / 185)}[/tex]
Simplifying further:
Standard Error ≈ [tex]\sqrt{((0.04) / 185)}[/tex]
Standard Error ≈ [tex]\sqrt{(0.0002162)}[/tex]
Standard Error ≈ 0.0147 (rounded to the nearest thousandth)
Finally, we can calculate the margin of error:
Margin of Error = 1.96 [tex]\times[/tex] 0.0147
Margin of Error ≈ 0.0288 (rounded to the nearest thousandth)

3.5(10n + 2n - 9) = 178.5
Answer:
n= 5
Step-by-step explanation:
3.5 (10n + 2n-9) = 178.5
Divide 3.5 on both sides
10n + 2n -9 +51
Add like terms to get 12n
12n - 9 = 51
12n = 51 + 9
Add 51 and 9 to get 60
12n + 60
Divide 60 by 12 to get 5
n=5
