<span>Sarah's conclusion is invalid, because she is testing two variables at once without a control value. In order for the experiment to be valid, Sarah should either apply the same soil to both areas (assuming they are, in fact, the same). Or, she should water both equally. At this time, we don't know if B grew "better" due to the brand or the amount of water received.</span>
Answer: c. 66

Since the triangles are similar, the corresponding sides are proportional.
Let the height of the flag pole be x feet.
We multiply both sides by 6 to get:
We reduce the fraction to get:
We now simplify
Answer:
They would have to order 4 more uniforms in order to distribute an equal amount to each employee
Step-by-step explanation:
First we have to calculate the number of maximum uniforms that can be given to each employee equally
For this we simply divide the number of uniforms by the number of employees and look only at the whole number
980/41 = 23.92 = 23
we don't round we just take the decimals
now we multiply the number of maximum uniforms that we can give each one by the number of employees
23 * 41 = 943
to the 980 uniforms we subtract the 943
980 - 943 = 37
Calculate how much is left to 37 to reach 41
41 - 37 = 4
This means that they would have to order 4 more uniforms in order to distribute an equal amount to each employee
