I SUCK CAN SOMEONE PLZ DO THIS EVEN WRITING IT OUT FOR ME!?!??
Ksju [112]
Jason is buying 2 hats and 3 scarves for each of his 4 children

so he is actually buying 8 hats and 12 scarves.

a hat costs 8.50 and a scarf costs 5.50

so you put it into a equation

8.50(h)+5.50(s) = P     h = hat, s = scarf, P = pay

8.50(8)+5.50(12) = P

68 + 66 = P

P = 134

hope this helps

Problem 2
Brilliant_brown [7]

Answer:

Let the 'cart' total is x and total payment is y.

The sales tax is 5.6% added to the 'cart' amount and then shipping and handling fee added.

<h3>Part A</h3>

<u>There are three intervals as below and function added accordingly:</u>

  • 0 < x ≤ 49.99      ⇒ y = x + 5.6% + 3.95 = 1.056x + 3.95
  • 50 ≤ x ≤ 75.99    ⇒ y = x + 5.6% + 11.95 = 1.056x + 11.95
  • x ≥ 76                  ⇒ y = x + 5.6% + 5.95 = 1.056x + 5.95
<h3>Part B</h3>
  • x = 74.50, this falls in the second interval
  • y = 74.50*1.056 + 11.95 = $90.62 (rounded )
<h3>Part C</h3>

y = 89.20, this is close to the number we got in part B and we assume it is same - the middle interval.

  • 89.20 = 1.056x + 11.95
  • 1.056x = 89.20 - 11.95
  • 1.056x = 77.25
  • x = 77.25 / 1.056
  • x = 73.15 (rounded )

-----------------------------------------

  • <em>Note. Shipping and Handling charges seems incorrectly ordered. If so the answers above all should change accordingly.</em>

I need help on this question. I don't want to get a bad grade. -_-
ch4aika [34]

Answer:

60.84 m

Step-by-step explanation:

The perimeter is the distance around

The distance around the 3 sides of the rectangle are

15+12+15

42

Now we are going 1/2 way around the circle

That is 1/2 of the circumference

1/2 C = 1/2 pi *d

         = 1/2 pi *12

          = 6pi

Using 3.14 for pi

          = 6 (3.14)

          =18.84

Add these together

42+18.84

60.84 m
