Step-by-step explanation:

First of all, figure out what you're trying to model. Second, decide what variable name you want to use to model it. Third, write the relationship expressed in the English statement.

Here, we're modeling the number of balls in the box. We choose 'b' to represent that number. We are told it is greater than 12, so our model is ...

A shopkeeper purchased hammocks for $800 and sold them at a discount of 25%. What was the selling price? Choose the correct option.

A $400

B $600

C $200

D $500

Answers

Answer:

B

Step-by-step explanation:

25% of 800 is 200, so 800-200 is 600

The selling price of the hammocks is $600.

What is selling price?

Selling price is the price that a customer pays to purchase a product or a commodity.

What is cost price?

Cost price is the total amount of money that it costs a manufacturer to produce a given product or provide a given service.

What is discount?

A reduction made from the gross (see gross entry 1 sense 3b) amount or value of something is called discount.

What is the relation between cost price, selling price and discount?

selling price = cost price - discount

According to the given question.

The cost price of hammocks = $800

The percentage of discount given by the shopkeeper for the hammock = 25%.

So,

The amount discount given by the shopkeeper

= 25% of 800

[tex]= \frac{25}{100} (800)\\[/tex]

= $200

Therefore, the selling price of the hammocks = $800 - $200 = $600

Hence, the selling price of the hammocks is $600.

A triangle has sides with lengths of 5 yards, 12 yards, and 13 yards. Is it a right triangle?

Answers

yes because the hypotenuse would be the longest side (13) and when squared equals 169. now when you square 5 and 12 (25 and 144) and add them, you get the 169, which is 13. so yes it’s a right triangle.

The distribution of time spent brushing teeth for the 1,200 students in a school is multimodal with a mean of 43 seconds and a standard deviation of 8.99 seconds. If a random sample of 9 students is selected, is it appropriate to calculate the probability of the sample mean being less than 30 seconds using an approximately Normal model? Yes, the population of 1,200 students is reasonably large in size, so the shape of the population is not a concern. Yes, the sample of 1,200 students is a reasonably large sample size, so the shape of the population is not a concern.

Can someone pls help me with question 21 ASAP due today show steps

Answers

Answer:

$ 11,169.85

Step-by-step explanation

First, convert R percent to r a decimal

r = R/100

r = 7%/100

r = 0.07 per year,

Then, solve our equation for A

A = P(1 + r/n)nt

A = 2,000.00(1 + 0.035/2)(2)(25)

A = $ 11,169.85

Summary:

The total amount accrued, principal plus interest,

from compound interest on an original principal of

$ 2,000.00 at a rate of 7% per year

compounded 2 times per year

over 25 years is $ 11,169.85.

Answer:

Crate weight = x, bricks weight =y

X+20y=167 - - - - - (1)

X+32y=191 - - - - - -(2)

Subtract 1 and 2

0-12y=-24

Then y=2 pounds

Substitute y in equation 1

X+40=167

Then x=127 pounds

Then when we have 19 bricks the weight will be

127+ 19*2= 165 pounds

Consecutive integers are integers that
differ by one. You can represent
consecutive integers as x, X + 1,
x + 2 and so on. Write an equation
and solve to find three consecutive
integers whose sum is 33.

Answers

Answer:   The three numbers are 10, 11, and 12.

10+11+12 = 33

=========================================================

Work Shown:

x = smallest numberx+1 = middle numberx+2 = largest number

Each is a positive whole number

Add them up and set the result equal to 33. Solve for x.

(x) + (x+1) + (x+2) = 33

3x+3 = 33

3x+3-3 = 33-3 .... subtract 3 from both sides

3x = 30

3x/3 = 30/3 ..... divide both sides by 3

x = 10

x+1 = 10+1 = 11

x+2 = 10+2 = 12

Note how 10+11+12 = 33 to help confirm our answer.
