John is creating a Thanksgiving display at the store where he works, using only canned pumpkin and canned green beans. He needs to maintain a ratio of pumpkin to green beans of 5 to 2. If he wants to use a total of 126 cans, how many cans of green beans should he use?
please help me lol
Answer:
90 pumpkin and 36 green beans
Step-by-step explanation:
Because there is a total of 7 parts (5+2) and I divided 126 by 7 and then put five of the 18ns (the quotient of 126 and 7) for pumpkins (so... multiply 18 by 5) then the other to times 18 is 36. And if you add them together, they equal 126.
Answer:
9 cans
Step-by-step explanation:
126/7=18
18/2=9
so 9 is the answer

You have 24 coins valued at $3.00. Some of the coins are dimes and some are quarters. Find the number of each coin that you have.
Answer:
10 Quarters and 5 dimes
Step-by-step explanation:
10 Quarters = $2.50
5 dime = $0.50
Answer:
20 dimes and 4 quarters
Step-by-step explanation:
So, a dime is 10 cents and a quarter is 25
So, let's say you have x dimes and y quarters
X+Y=24 (total amount of coins)
Also,
10x+25y= 300 (cents)
I just put the 3 dollars into cents
Now, you have a system of equations and we should solve it:
X+y=24 ----x=24-y
10x+25y=300
So substitute x in the 2nd equation
10(24-y)+25y=300
240-10y+25y=300
240+15y=300
15y=60
y=4
Now that you know the amount of quarters, you can just say that you will have 20 dimes since 24-4=20
So, 4 quarters and 20 dimes
Check:
20 dimes=2 dollars
4 quarters= 1 dollar
correct

Answer:
10 I think
Step-by-step explanation:
well we add it all together 2+1+3+4
Answer:
9
Step-by-step explanation:
Split up the shape into 2 seperate shapes (I did a trapezoid and)
Rectangle:
1*4 = 4
Trapezoid:
3 - 1 = 2 (for trapezoid's height)
4 - 2 = 2 (for trapezoid's shorter base)
(3 * [tex]\frac{1}{2}[/tex]) * (2 + 4) =
1.5 * 6 = 9
what do I do here???
Answer:
8 plus 8 then 4 plus 4 then add those, so your answer would be 24 cm
It takes 36 slices of pepperoni to make 4 pizzas. How many pizzas can be made using 90 slices of pepperoni?
Answer:
