For company a ( $376 + $12 an hr) it would take 2 hours because 376+12= 388+12= 400 (376 + (12 x 2) )

for company b, ( $280 + $15 ) it would take 9 hours because 280 + 15 = 295 + 15 =
310 + 15 = 325 + 15 = 340 + 15 = 355 + 15 = 370 + 15 = 385 + 15 = 400 (280 + (15 x 8))



376 x (12 x 2)
376 x 24 = 400

280 x (15 x 8)
280 x 120 = 400



1) a = 2 hrs
b = 8 hrs

2) $400

Which quiz did met have a better score?
MaRussiya [10]
I'm her first quiz she did better, this is going to be hard to explain but pay attention 92% as a decimal is 92/100 keep this in mind, then 27 out of 30 question we try to make 30 go into 100 but we know 30 can't go into 100 without a decimal so what we do is we change the decimal to 90 so for the 27 out of 30 it is now 81/90, now we need to change the denominator in 92/100 to 90 so we subtract 10 from the numerator and denominator to get 82/100 so compare the 2 decimals you got 81/90 and 82/90 and you find that 82/90 is bigger so she did better on the first quiz

Given the following functions f(x) and g(x), solve (f ⋅ g)(3) and select the correct answer below:
Ksenya-84 [330]
I believe you may have the order incorrect. If we were looking at g(f(x)) the answer would be 47. We would get this by sticking the 3 in for x in f(x) and solving, which would give us 48. We would then stick that answer in for x in the g(x), giving us 47. 

In its current order the answer would be 28.

What is the area of the right triangle shown?
prisoha [69]
The 30:60:90 proportion is 1:sqrt 3: 2

So,

x = 10/2
x = 5

y = 10/sqrt 3

Finding the area:

1/2 * 5 * 10/sqrt 3
25/sqrt 3

Hope this helps!
