What exponent should Marina use for b?

Answers

Answer 1

The exponent Marina should use for b is: D. 7.

How to Divide Exponents with the same Base?

When dividing, you subtract the exponents. I.e. [tex]a^m \div a^n = a^{m - n}[/tex].

Using the rule, we would also subtract the exponents of b in the simplified expression. Thus:

[tex]b^4 \div b^{-3}[/tex]

Subtract the exponents

4 -(-3) = 4 + 3 = 7.

Therefore, the Maria should use the exponent b = 7.

In the winter how many dell customer would it be in the spring

Answers

Answer:

100 customers

Step-by-step explanation:

The computation of the number of dell customers would be in the spring is shown below:

Given that

In winter season

The ratio of daily customers to weekly customers  = 1:5.

In Spring season :

The ratio of daily customers to weekly customers = 4:2.

And, the Number of the weekly customer in the winter is 125

So if we can see that the weekly customers would be 5 times of daily customers  

So, the daily customers in winter is

= 125 ÷ 5

= 25 customers

Now in the spring it would be

= 25 × 4

= 100 customers

1 Which of the following could be the sides of a right triangle? Check all that apply. A. 10, 24, 26 B. 4, 5, 9 C. 18, 24, 30​

Answers

Answer:

A and C

Step-by-step explanation:

Let Triangle ABC is a right angle traingle.

From Option A

AB= 24, BC= 26 and AC=10

By Pythagorean Triplet

(AB)^2 + (AC)^2 = (24)^2 + (10)^2

= 576+100

(AB)^2 + (AC)^2 = 676 ---------------- (I)

(BC)^2 = 26^2 = 676 -------------------(ii)

From (I) and (ii)

(BC)^2 = (AB)^2 + (AC)^2

Therefore, the sides 10,24 and 26 are the sides of the right angle triangle.

From Option C

AB= 18, BC= 30 and AC=24

By Pythagorean Triplet

(AB)^2 + (AC)^2 = (18)^2 + (24)^2

= 324+576

(AB)^2 + (AC)^2 = 900---------------- (I)

(BC)^2 = 30^2 = 900 -------------------(ii)

From (I) and (ii)

(BC)^2 = (AB)^2 + (AC)^2

Therefore, the sides 18, 24 and 30 are the sides of the right angle triangle.

Axel owns stock in a company. He purchased the stock In January at a price of $250 a share. From January to February, the stock price decreased by 38% a share. From February to March, the stock price increased by 20% a share. By what percentage did the price of the stock decrease per share from January to March?

Answers

Answer:

25.6%

Step-by-step explanation:

Purchase price = $250 / share

Jan - feb : 38% decrease

(100 - 38)% * 250 = $155

February - March : 20% increase

(100 + 20)% * $155

120% * $155 = $186

Percentage decrease from January to March :

[(250 - 186) / 250] * 100%

(64 / 250) * 100%

0.256 * 100%

Two rectangular rugs are ordered at Cardi’s furniture: small rugs and large rugs.

Small rugs are 36 inches long and 18 inches wide.

Large rugs are 90 inches long and 45 inches wide.

a. Are the rugs similar shapes? Explain your reasoning.

b. Find the ratio of the two perimeters and the ratio of the two areas. Is there anything you notice about these ratios? What can you deduce?

c. It takes 180 feet of yarn to create a square foot of either rug. How many inches of yarn are needed to make the small rug? How many feet or yarn is needed to make the large rug?

d. If a “skein” of yarn costs $4.50 and one skein is exactly 180 feet of yarn, how many skeins of yarn are needed to make the large rug? Given this answer what is the lowest Cardi’s must sell the large rug in order to make a profit

PLEASE HELP EVEN IF U CAN ANSWER JUST 1

Answers

Answer:

a.) yes they are similar shapes, the width for both rugs is 1/2 of the length. This means that they are both similar in shape.

b.) 2:5 (perimeter rug 1 and 2 compared), 4:25 ( area for 1 and 2). The numers in the perimeter ratio are the square root of the numbers in the area ratio.

c.) You will need 648 sq in for the small rug and 4050 sq in for the large rug.

d.) 2:  she has to sell the large rugs x>$9 and the small rugs for s>$1.50

Step-by-step explanation:

total perimeter for rug 1 = 108   For rug 2 = 270

area for run 1 = 648 For rug 2 = 4050

180 ft =  2150 in

The large rug needs two skeins of yarn which cost 9 dollars, if she wants to make a profit she will have to sell them over that price.

You can make 3 small rugs with one skein meaning if she wants to make a profit from the small rugs she has to sell them over 1/3 of the price of the skein (which is sold for $4.50). She will have to sell the small rug for over $1.50
