Answer: 13 ft

7 ft

Step-by-step explanation:

Assume that the wire is cut in half.

That gives us 10 ft each piece

However, one piece is 6ft longer then the other

Only two compatible numbers:

The length of the longer piece is: 13 ft

The length of the shorter piece:<em> 7 ft</em>

Marie purchased a 29.00 gift. She uses a coupon that offers 30 percent. How much will she spend on the gift after the coupon?
asambeis [7]

Answer:

$20.30

Step-by-step explanation:

The usual price of the gift is $29.00

Marie will get 30% DISCOUNT on this price if she uses her coupon. So, the final price would be 30% less than $29.00

First, we need to find 30% of $29.00. Then we need to subtract that from original price (29).

Convert percentage to decimal first:

30% = 30/100 = 0.3

Now multiply this with 29 to get:

0.3 * 29 = $8.70

We subtract this from original price to get DISCOUNTED PRICE:

$29.00 - $8.70 = $20.30

What is the slope hurry!!!!! please !!!!!!
Nina [5.8K]

Answer:

It’s definitely 1/4

Step-by-step explanation:

the answer shoudl be positive since its a positive line

And t can’t be 4 becuase then the line would be slanted upward as becuase 4 up 1 right and this looks more like of a 1 up, 4 right. Try it yourself, try slope fo 4 from the origin since its a gaurteed point in this situation and try 4 and 1/4. 1/4 is way more reasoabnable,

If Hannah gives her younger sister 3 shirts, it does not matter what order she hands them to her. No matter the order, it will still be the same group of 3 shirt. Since order is not important this problem can be solved using a combination. 
Specifically, we are asked to find 8C3 (sometimes called "8 choose 3"). This is a fraction. In the numerator, we start with 8 and count down 3 numbers. In the denominator, we start with 3 and count all the way down to 1.
your answer is 56
