Answer:
Yes, the boats are safe to ride.
Step-by-step explanation:
40 (4) + 12 (2) ≤ 500
160 + 24 ≤ 500
184 ≤ 500
184 is less than 500.
because I was not sure if you had 9 adults instead of 2, this is the answer:
40 (4) + 12 (9) ≤ 500
160 + 108 ≤ 500
268 ≤ 500
268 is less than 500

Hi!
We will solve this using proportions, like this:
3/4 cup for 8 slices of pie
x cup for 48 slices of pie
_______________________
x = ((3/4)*48)/8
x = (3*48)/(4*8)
x = 144/32
x = 4,5
You need 4 1/2 cups of white sugar for 48 slices of pie.
Hope this helps!
Answer:
I believe the answer is (-7.4) Not really great at math either
Step-by-step explanation:
Answer:
4.5 % alloy
Step-by-step explanation:
Let x = amt of 30% alloy
The resulting total is to be 25 oz, therefore:
(25-x) = amt of 5% alloy:
A typical mixture equation:
.30x + .05(25-x) = .20(25)
.30x + 1.25 - .05x = 5 .30x - .05x = 5 - 1.25
.25x = 3.75
x = 3.75%2F.25
x = 15 oz of 30% alloy required
then
25-15 = 10 oz of 5% alloy:
Check solution
.30(15) + .05(10) = .20(25)
4.5 + .5 = 5
