"Our customer retention rate has decreased 10% from last quarter's goal of 250 consumers retained. We need to increase our curre
Zina [3914]

1. Calculate 10% of 250 (250 × 0.10 = 25)
2. Subtract that from 250 (250 - 25 = 225)
3. Then find 16% of 225 (225 × 0.16 = 36)
4. Add 225 and 36 to get 261
5. Therefore, the target number of consumers retained is 261

A storage closet holds twelve boxes stacked upon each other, with each box being 10 inches high. How many feet are there between
babunello [3635]

Answer: 5

Explanation step-by-step: There are six boxes stacked between the top of the third box and the bottom of the tenth box.

Since each box measures 10 inches in height, the combined height of these six boxes is 60 inches.

Given that 12 inches equals 1 foot,

60 inches corresponds to 5 feet.

How to find the answer:

Let "y" represent the unknown length in feet.

12 inches = 1 foot

60 inches = y

Using cross multiplication:

> 12 × y = 60 × 1

> 12y = 60

Divide both sides by 12 to solve for "y":

> 12y ÷ 12 = 60 ÷ 12

After simplification, we get:

> y = 5

Oscar rides his skateboard 5/8 mile in 1/4 hour. How fast, in miles per hour, does he ride his skateboard?
Inessa [3907]

Answer:

The speed is 2 1/2 miles per hour.

Step-by-step explanation:

To determine the rate, divide the distance by the time taken.

5/8 mile ÷ 1/4 hour

Applying the copy dot flip method:

5/8 * 4/1

Gives us 5/2 miles per hour.

Which simplifies to 2 1/2 miles per hour.

Engineers measure angles in gradients, which are smaller than degrees. The table shows the conversion of some angle measures in
tester [3916]
The following table presents the conversion from degrees to gradients.

To calculate the slope, we take the difference between the two y-values (gradients) and divide it by the difference between the corresponding x-values (degrees).

For this purpose, we will use the initial and final points listed in the table. Therefore, the slope m is calculated as:

m= \frac{300-(-200)}{270-(-180)}  \\  \\ 
m= \frac{500}{450} \\  \\ 
m=1.11

After rounding to two decimal places, the slope of the line converting degrees to gradients is 1.11

What is the following quotient? StartFraction StartRoot 6 EndRoot + StartRoot 11 EndRoot Over StartRoot 5 EndRoot + StartRoot 3
babunello [3635]

Answer:

StartFraction StartRoot 30 EndRoot minus 3 StartRoot 2 EndRoot + StartRoot 55 EndRoot minus StartRoot 33 EndRoot Over 2

Step-by-step explanation:

We are given the surdic equation depicted in \frac{\sqrt{6}+\sqrt{11} }{\sqrt{5}+\sqrt{3} }\\.

To calculate the quotient, we will rationalize by multiplying both the numerator and denominator of the function by the conjugate of the denominator.

The denominator shown in \sqrt{5}+\sqrt{3} has a conjugate of \sqrt{5}-\sqrt{3}.

After multiplying by \sqrt{5}-\sqrt{3}, we achieve;

= \frac{\sqrt{6}+\sqrt{11} }{\sqrt{5}+\sqrt{3} } * \frac{\sqrt{5}-\sqrt{3} }{\sqrt{5}-\sqrt{3} }\\

= \frac{\sqrt{30}- \sqrt{18}+\sqrt{55}-\sqrt{33}}{2}\\= \frac{\sqrt{30}- \sqrt{9*2}+\sqrt{55}-\sqrt{33}}{2}\\= \frac{\sqrt{30}- 3\sqrt{2}+\sqrt{55}-\sqrt{33}}{2}

The resulting expression provides the needed answer.
