Miles bought a new pair of baseball cleats for $64.95. The sales tax is 6.5%. What is the total cost that Miles will pay?

Answers

Answer: $69.17175

Step-by-step explanation:

The cleats are $64.95. Tax is a percentage taken off certain goods so

6.5% of $64.95 which can be also restructured as 6.5/100 times $64.95 which is $4.22175. Tax is added onto the final cost so he shall pay $64.95 plus $4.22175. (I think)

Solution: 4/6 apples.

Step-by-step explanation:

Explanation:

Aladdin has 4/6 apples because 1/6 multiplied by 4 is the same thing as adding 1/6 by 1/6 by 1/6 by 1/6.

Shaquille, Lyle, and Amanda collect stamps. Shaquille has one-half the number of stamps that Lyle has. Amanda has two-thirds as many stamps as Lyle. Together they have 364 stamps. How many stamps does Amanda own?

Answers

amanda owns 112 stamps

Answer:

Amanda has 112 stamps

proof:

Lyle has 168 stamps

Shaq has 84 stamps

Step-by-step explanation:

S = number of stamps Shaquille has

L = number Lyle has

A = number Amanda has

S = 1/2L

A = 2/3L

S + L + A = 364

substituting for S and A

1/2L + L + 2/3L = 364

reduce

2 1/6L = 364

divide both sides by 2 1/6

L = 168

S = 1/2(168) = 84

A = 2/3(168) = 112

A furniture store offers free setup and delivery services to all points within a 25-mile radius of its warehouse distribution center. If you live 20 miles east and 14 miles south of the warehouse, will you incur a delivery charge? JUSTIFY YOUR ANSWER!

I am confused. I don't know what to dooo

Answers

Answer:

No

Step-by-step explanation:

you can make a right triangle with 20 and 14. To find the hypotenuse, you add

20² + 14² = h²

400+196 = h²

596<25²

596<625

which is true.

Yes , the person will get free delivery as the person lives in the 25 mile radius.

What is a Right Angled Triangle ?

A right triangle is a triangle with one of its side as 90  degree.

It is given that the person lives 20 miles east and 14 miles south of the warehouse.

The warehouse gives free delivery for people in 25-mile radius

The distance between the warehouse and the house ≤ 25 mile

To determine the distance a right angled triangle is considered

The base is 20 and height is 14 , hypotenuse = ?

Hypotenuse ≤ 25

[tex]\rm \sqrt { 20^2 + 14^2}[/tex] ≤ 25

24.43 ≤ 25

So , Yes the person will get free delivery as the person lives in the 25 mile radius.
