Answer:
1.44
Step-by-step explanation:
To solve this problem all you have to do is multiply the number in the parentheses the number of times the exponent is.
1.2 x 1.2 = 1.44
Hope this helps :)

Recall that

and so replacing

with

, you get that the second limit is 1. Meanwhile,

so the limit is 0.
40 hrs at 8 bucks, 40*8 or 320, now, is 2 workers, so 320+320 or 640
so... how much is 640 from 2000 in percentage? well, if we take 2000 as the 100%, then

solve for "x"
Hey John
Let's start solving #1
x/4 = 3.5/28
Cross multiply
(x)(28) = (3.5)(4)
28x = 14
Divide both sides by 28
28x/28 = 14/28
x = 1/2
Next, let's solve the second one

Simplifies to:

Cross multiply
(105x + 75)(5) = (28)(50x)
525x + 375 = 1400x
Subtract 1400x to both sides
525x + 375 - 1400x = 1400x - 1400x
-875x + 375 = 0
Then subtract 375 from both sides
-875x + 375 - 375 = 0 - 375
-875x = -375
To find x, divide both sides by -875
-875x/-875 = -375/-875
x = 3/7
Let me know if you have questions about the answer.
Best of luck with your studies!
