Sati [7]

Answer:

The profit of the bakery for this batch of rolls is C. $ 132

Step-by-step explanation:

You know the following this about the problem:

xy=300 is the total cost of the production of the rolls, where x is the cost of the rolls and y is the number of rolls.
Day 1 the bakery sold 4/5 of the rolls at 1.50 its value.
Day 2 the bakery sold 1/5 of the rolls ar 0.8 of the price of Day 1.

$Day1=1.50x\frac{4}{5}y=\frac{3}{2}x\frac{4}{5}y=\frac{6}{5}xy\\Day2=0.8\frac{3}{2}x\frac{1}{5}y=\frac{4}{5}\frac{3}{2}x\frac{1}{5}y=\frac{6}{25}xy$

The total gain of the sales is:

Day 1 + Day 2

$Day1+Day2=\frac{6}{5}xy+\frac{6}{25}xy=\frac{36}{25}xy$

and you know that xy =300, then the total gain is:

$gain=\frac{36}{25}(300)=432$

And the profit is the total gain less the total cost:

Profit = 432-300=132

Can you please explain how to do this and give me the answer so next time I know how to do it. Square root with -15 in it and sq

Drupady [299]

Answer:

15i and 4i

Step-by-step explanation:

i is an imaginary number also shown as $\sqrt{-1}$ .

Since we have $\sqrt{-15}$ , thats 15* $\sqrt{-1}$ . Substitute $\sqrt{-1}$ for i and we get 15*i or 15i.

We do the same for $\sqrt{-4}$ . This is 4* $\sqrt{-1}$ or 4*i or 4i.

An easy way to do this is to take the negative inside the square root like $\sqrt{-6}$ , take the absolute value -6 absolute value=6 and times it by i. So now it becomes 6i

13. g

14. b

Step-by-step explanation:

1. a quotient of two quantities -> h. fraction

2. a quotient that involves variables -> k. algebraic fraction

3. numbers that would result in division by zero -> d. exclusions

4. multiply the numerators and multiply the denominators for a new fraction -> j. multiplication of fractions

5. multiply by the reciprocal of the divisor -> m. division of fractions

6. the denominators must be the same -> n. addition of fractions

7. contains a fraction in the numerator, denominator, or with the denominator -> a. complex fractions

8. a new fraction resulting from the interchanging of the numerator and denominator -> l. reciprocal

9. the dividend of a fraction -> e. numerator

10. the divisor in a fraction -> c. denominator

11. the lowest common multiple of denominators -> f. lowest common denominator

12. a combination of integral and fractional expressions -> i. mixed expression

13. an equation that contains fractions -> g. fractional equation

14. a statement that two fractions are equal -> b. proportion

Jenny owns a salon. She had 150 customers at the end of the third quarter, 151 customers at the beginning of the third quarter,

There is a 96% customer retention rate for the third quarter.

Given

Jenny owns a salon.

She had 150 customers at the end of the third quarter, 151 customers at the beginning of the third quarter, and five new customers in the third quarter.

<h3>Customer retention rate;</h3>

It determines the percentage of customers that the company has retained over a given period.

The customer retention rate is determined by;

$\rm Customer\ retention\ rate=\dfrac{Given \ period - New \ customers}{Initial \ number}\times 100$

Substitute all the values in the formula;

$\rm Customer\ retention\ rate=\dfrac{Given \ period - New \ customers}{Initial \ number}\times 100\\\\\rm Customer\ retention\ rate=\dfrac{150-5}{151}\times 100\\\\\rm Customer\ retention\ rate=\dfrac{145}{151}\times 100\\\\\rm Customer\ retention\ rate=0.96 times 100\\\\\rm Customer\ retention\ rate=96 \ percent$

Hence, there is a 96% customer retention rate for the third quarter.
