Can u guys help me please with 5,6,7,8

An explanation for this is that a straight line has a angle degree value of 180. Therefore if you draw the line that creates a 139 degree angle, the rest of the line would have an angle measurement of what is left of the 180 degrees. So to get x you would start with the 180 degree straight line value and subtract the 139 degrees of the line that divides it. so equation is:
180 - 139 = x
And and you get 41 degrees.
(To word this another way the two angles of x and 139 have to add up to the straight line of 180 degrees. Therefore another equation could be:
139 + x = 180
which is basically the same equation but might be easier explanation for some to understand.)

questions 7 and 8 are the same but instead of straight line with 180 degrees, you start with right angle with 90 degrees. Therefore x and the 18 degree angle have to add up to 90 degrees making an equation of:
x + 18 = 90
Or
x = 90 - 18
answer would be
x = 7w

A company produces packets of soap powder labeled "Giant Size 32 Ounces." The actual weight of soap powder in such a box has a N

Nataliya [291]

Answer:

C. 34.15 oz

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu= 33, \sigma = 0.7$

How heavy does a box have to be for it to be labeled overweight?

Top 5%, so X when Z has a pvalue of 1-0.05 = 0.95.

So X when Z = 1.645.

$Z = \frac{X - \mu}{\sigma}$

$1.645 = \frac{X - 33}{0.7}$

$X - 33 = 0.7*1.645$

$X = 34.15$

So the correct answer is:

C. 34.15 oz

Eve plays basketball. She makes 5 free throws for every 3 free throws that she misses. If she missed 36 free throws at her last

jenyasd209 [6]

Answer:

60

Step-by-step explanation:

We can write a proportion to solve

5 made x made

------------ = -----------

3 missed 36 missed

Using cross products

5 * 36 = 3x

Divide each side by 3

5 * 36/3 = 3x/3

50 = x

She made 60

math 115 In a recent year, wind machines in a country generated 181.3 billion kWh of electricity, enough to serve over 17 millio

vivado [14]

Answer:

The percentage of of the total energy production was generated by wind machines is 4.43%.

Step-by-step explanation:

Percentage is the proportion of an item in the whole.

The formula is:

$Percentage=\frac{X}{N}\times 100$

It is provided that the wind machines in a country generated 181.3 billion kWh of electricity.

And the nation's total electricity production that year was 4,096 billion kWh.

Compute the percentage of of the total energy production was generated by wind machines as follows:

$Percentage=\frac{181.3}{4096}\times 100=4.43\%$

Thus, the percentage of of the total energy production was generated by wind machines is 4.43%.
