Answer: 1 1/12 (aka 13/12)

Step-by-step explanation: First, I did 3 x 1/4 (3/4) and with 3/4, I used the denominator (4) and multiplied both the numerator and denominator (with this I used 1/3) and multiplied 3 x 4 and 1 x 4 and got 4/12. Now I take the denominator of 3 (from 1/3) and multiply the numerator and denominator from the 3/4, and 3 x 3 and 3 x 4 which got me 9/12. Lastly, I did 9/12 and 4/12 and got 13/12 which is just 1 1/12

Answer:

D. 32

Step-by-step explanation:

For this problem, we simply plug -9 in for x in f(x):

$f(x)=\frac{1}{3} x^2+5$ ⇒ $f(9)=\frac{1}{3} *(9^2)+5=\frac{1}{3} *81+5=27+5=32$

Thus, the answer is D. 32.

Hope this helps!

Answer:

economy class = 260

business class = 100.

Step-by-step explanation:

for every 13 economy seats, there are 5 business class seats

EC = 13

BC = 5

ADD to get total = 18

divide 360 by 18 to get the number of groups created.

you get 20.

multiply 20 by each class seats

13 by 20 = 260

5 by 20 = 100

you can confirm by adding the seats to see if you will get 360.

Terrence finished a word search in 3/4 the time it took frank. charlotte finished the word search in 2/3 the time it took terren

Luden [163]

Answer:

Charlotte-16

Step-by-step explanation:

In order to calculate the time that Charlotte took we just first have to calculate the time that Terrence took to finish the word search, that is done by multiplying the 32 minutes that Frank took by the three quartes that it took terrence:

$Time=(\frac{3}{4}) (32)\\Time=(\frac{96}{4})\\Time=24$

So now we know that It took terrence 24 minutes, and that Charlotte took two thirds of that time so we now just multiply that:

$Time=(\frac{2}{3}) (24)\\Time=(\frac{48}{3})\\Time=16$
