The value of x is 8.25
x+9/28 = 20*3/7
x=60/7 - 9/28
x = 33/4
x= 8.25
The answer is B. 36.
the ratio is 4:2, the number 4 is twice as much as 2. so if there's 18 algebra problems (representing the 2 in the ratio), then there would be twice as many data analysis problems. 18 times 2 equals 36. :) hope it helps!
Answer:
V = 140 pi ft^3
Step-by-step explanation:
The volume of a cone is given by
V = 1/3 Bh where B is the area of the base
V = 1/3 (35 pi) * 12
V = 4*35 pi
V = 140 pi ft^3
We cannot approximate pi if we want the exact answer
Answer: Ayden has 11 football cards,44 baseball cards and 51 Pokemon cards which totals 106 cards all together
Step-by-step explanation:
STEP 1 :
Let x represent number of football cards
He has four times as many baseball cards as football cards, let baseball cards be = 4x
Pokémon cards contain 7 more cards than his baseball collection,let Poke mon cards = 4x +7
Step 2 :
Putting in equation we have that
Football cards + Baseball cards + Pokemon cards = 106 cards
Therefore,
x + 4x + 4x+7 = 106
9x + 7 = 106
9x = 106-7
9x = 99
x =99/9 = 11
therefore football cards , x = 11 football cards
baseball cards = 4x = 4 x 11 = 44 baseball cards
Pokemon cards = 4x+7= 4x11 +7 = 44 +7 =51 Pokemon cards
Answer:
It will take 
weeks to recycle a total of 45 kg of paper
Step-by-step explanation:
W represents the number of weeks the office has been on the new recycling plan
P represents the total kilograms of paper recycled.
It took weeks to recycle P kilograms of paper = W
It took weeks to recycle 1 kilogram of paper =
It took weeks to recycle 45 kilograms of paper =
Hence It will take weeks to recycle a total of 45 kg of paper
