Answer: 6
Explanation
If we divide our figure into six, we get the following figure:
As we can see, we are left with 6 equal parts. This can be confirmed by solving the equation:
Answer:
Step-by-step explanation:
If the tank holds 2500 liters and there are already 750 liters in there, he only needs to buy 1750 liters.
If he is saving 6%, he is still spending 94%, so
.94(58.4) = 54.896 (what he'll be paying per liter after the 6% comes off, then
54.896(1750) = $96,068
Jesse, to answer this, we need to see the graph. I'd help if I could! You can message me if you post it! :D
Answer:
50 cents
Step-by-step explanation:
Let's set up a system of equations. Let x be a cookie and y be a brownie then...
x+2y=2x+y
x+y=1
We can solve this using substitution
x=1-y
1-y+2y=2(1-y)+y
1+y=2-2y+y
1+y=2-y
-1=-2y
y=1/2
One brownie costs 50 cents and one cookie costs...
x+1/2=1
x=1/2
One cookie costs 50 cents
The estimated portion of light bulbs that last more than 500 hours will be
x=∑xn=224/430=0.521=52.1%
