If Erika and Bradley want to hike 11 miles each day, how many days will they hike exactly 11 miles?

Answers

it will take erika and bradley to travel 71 miles in 6.45 days
It will take them 6.45 days to hike 71 miles taking 11 miles on a day.

We know this because you just take 11 and divide it by 71. It gives you 6.454545454545455 but since it’s s repeating number we just leave it at 6.45!

A hat at the store is being offered at a 15% discount. If the original price of the hat is x, which answer choice shows an expression that represents the discounted price of the hat?

Answers

.85x is the discounted price of the hat

The discounted price of the hat is 0.85x.

What is discounted price?

Discount is the difference between the marked price (list price) and the selling price of an article. Therefore, the formula used for discount calculation is: Discount = List price - selling price.

Given that, a hat is at 15% discount price, we need to find the expression that represents the discounted price of the hat,

The discount = x - SP

15% of x = x - SP

SP = 85% of x

SP = 0.85x

Hence, the discounted price of the hat is 0.85x.

Answer:

about 3.1%

Step-by-step explanation:

I hope that helped you

Answer:

Hello!

The formula for percentage increase is:

Percent Increase = {( New Value - Old Value) / Old Value × 100}

Substitute = {( 566.60 - 550) / 550 × 100]

Solve:

566.60 - 550 = 16.6

16.6 / 550 = 0.0301818182

0.0301818182 × 100 = 3.0181818182

You may round that to 3.1%

So, Mr. Dawkins' salary increased by about 3.1%

A pair of running shoes cost 60.00. The sales tax is 3%. How much is sales tax?

Answers

Answer:

$1.8

Step-by-step explanation:

$1.8 is correct!

Explaination:

60*0.03= 1.8

Convert the percent to a decimal and multiply the cost by that decimal.

Examples:
1% = 0.01
100% = 1.00.
50% = 0.5
200% = 2.00

If the equation was $100 with a tax of 5%, then you would do 100*0.05 = $5

Algebra I

Terms/CoefficientsCoordinates (x, y)Solving systems of equation using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

3y = -5x - 3

y = -x + 1

Step 2: Rewrite Systems

Equation y = -x + 1

[Multiplication Property of Equality] Multiply everything by -3:                   -3y = 3x - 3

Step 3: Redefine Systems

3y = -5x - 3

-3y = 3x - 3

Step 4: Solve for x

Elimination

Combine 2 equations:                                                                                   0 = -2x - 6[Addition Property of Equality] Add 6 on both sides:                                  6 = -2x[Division Property of Equality] Divide -2 on both sides:                              -3 = x

Step 5: Solve for y

Define original equation:                                                                               y = -x + 1Substitute in x:                                                                                                y = -(-3) + 1Simplify:                                                                                                           y = 3 + 1Add:                                                                                                                 y = 4
