The complete question is
John and Matt are going to fill a pool with 2 different sized hoses. John can fill the pool in 5 hours, while Matt can complete it in 10 hours.How long will it take both to fill the pool? Explain each step in solving this equation.
we know that
<span>John can fill the pool in --------------> 5 hours
</span>therefore
<span>I calculate the amount of pool that John fills in one hour
</span>if John can fill 100% of the pool in----------------> 5 hours
X--------------------------------------> 1 hour
X=1/5=0.20 pool/hour
Matt can fill the pool in --------------> 10 hours
therefore
I calculate the amount of pool that Matt fills in one hour
if Matt can fill 100% of the pool in----------------> 10 hours
X--------------------------------------> 1 hour
X=1/10=0.10 pool/hour
<span>adding both amounts
(0.20+0.10)=0.30 -----------> 30% pool/hour
then
</span>if both can fills 30% of the pool in----------------> 1 hour
100%-------------------------------> X
X=100/30=3.33 hours----------> 3 hours + 19 minutes+ 48 sec
the answer is 3.33 hours (3 hours + 19 minutes+ 48 sec)
<span>The equation to determine the amount of pool filling (y) according to time (t) in hours is given by
</span><span>y=0.30*t
</span>
Answer:
hi
Step-by-step explanation:
for number 5, you take the area of the area of the fountain, which is pi * radius squared. this is equivalent to 3.14 * 4^2. then to simplify I made it 3.14 times 16 and then got the answer of 50.24. Then you take the area of the fountain plus the path, which makes the diameter 9.5 divide that by 2 to get the radius, which is 4.75. pi * 4.75^2 is about 70.85. then you subtract the two(70.85-50.24) to get 20.61. since its 10 dollars per square meter, you multiply 20.61 by 10 to get 206.10 dollars. That is your answer.
Answer:
It isn't factorable.
Step-by-step explanation:
Step 1: Write out expression
-625x⁴ + 1674
From here, the expression is already simplified/factored into it's final form. There is no way to reduce this.
