Essentially, 50% of $10.56 is $5.28.

This means that all we have to do is add $10.56 to $5.28, making $15.84

Side note: Another way that you can do this is by simply doing 1.5(10.56).

A department store sold 62 shirts one day. All short-sleeved shirts cost $11.00 each and all long-sleeved shirts cost $17.00 eac

slava [35]

Answer:

a. Short-Sleeve = 35

b. Long-Sleeve = 27

Step-by-step explanation:

Given data:

Total shirts sold = 62

short sleeved cost = 11 each

Long sleeved cost = 17 each

Total receipts = 844

Let the count of short sleeved be X and Let the count of long sleeved be Y

X + Y = 62 (equation 1) from the total shirts sold

11X + 17Y = 844 (equation 2) from the total receipts

From equation 1 X = 62 - Y (Equation 3)

Substituting equation 3 into equation 2

11(62 - Y) +17Y = 844

682 -11Y + 17Y = 844

-11Y + 17Y = 844-682

6Y = 162

Therefore Y = 27

Substituting Y into equation 3

X = 62 - Y

X = 62 - 27

X = 35

Hey guys help my please !!Q 4,6,7

padilas [110]

Q4, 4y²=60
y=√15 ( i am not sure)
q6, (5+y) ²=81
5+y=9
y=4
q7 (x+4) (x) =77
x²+4x-77=0
(x+11) (x-7) =0
x=-11(rej) or x=7
therefore ,length= 7+4=11cm
breadth=7cm
