Problem
How many 50-pound bags can you fill with one cubic yard of topsoil?
Result
About 83.
Solution
This is a division problem. So, we're going to divide the weight of one cubic yard of topsoil by 50
4,128 ÷ 50 = 82.56
Rounding to the ones place, we get 83.
Answer:
A. 37.5°
Step-by-step explanation:
∠SPT can be considered an inscribed angle in the circumcircle. In that circle, arc ST would have a measure of 360°/8 = 45°. Angle y° is half that measure, so is 22.5°.
The external angles of a regular octagon are 360°/8 = 45°, so that is the measure of angles UTW and UVW. It is also the amount by which reflex angle TUV exceeds 180°.
The sum of the interior angles of quadrilateral TUVW is ...
45° +225° +45° +3x° = 360°
Then 3x° = 45° and x° = 15°.
Then the sum of interest is ...
x° + y° = 15° + 22.5° = 37.5°
The value of z score for the history class test of Opal’s test score is negative one (-1).
<h3>What is normally distributed data?</h3>
Normally distributed data is the distribution of probability which is symmetric about the mean.
The mean of the data is the average value of the given data. The standard deviation of the data is the half of the difference of the highest value and mean of the data set.
The z score for the normal distributed data can be given as,

The mean value of the scores of history class is,

The standard deviation value of the scores of history class is,

Here, the test score of the Opal’s is 72. Thus the z score for her test score can be given as,

Hence, the value of z score for the history class test of Opal’s test score is negative one (-1).

The quotient of 2 3 / 5 ÷ 1 2 / 5 as a mixed fraction is 1 6 / 7
<h3>What is quotient?</h3>
Quotient is the answer obtained when we divide one number by another. Therefore,
2 3 / 5 ÷ 1 2 / 5
let's convert the mixed fraction to improper fractions.
2 3 / 5 = 13 / 5
1 2 / 5 = 7 / 5
Therefore,
13 / 5 ÷ 7 / 5 = 13/ 5 × 5 / 7
13/ 5 × 5 / 7 = 13 / 7 = 1 6 / 7
Therefore, the quotient of 2 3 / 5 ÷ 1 2 / 5 is 1 6 / 7
