$\bf \textit{volume of a cylinder}\\\\
V=\pi r^2 h~~
\begin{cases}
r=radius\\
h=height\\
-----\\
V=271.4\\
r=6
\end{cases}\implies 271.4=\pi (6)^2h\implies \cfrac{271.4}{\pi (6)^2}=h$

Question

puteri [66]

Answer:

The salt concentration of the mixed solution = 10%

Step-by-step explanation:

First assuming that the concentration of salt given is on a vol% basis.

First solution has 0.7 gallon of 5% salt

Amount of salt in this solution = 5% × 0.7 = 0.035 gallon

Second solution has 0.3 gallon of 22% salt

Amount of salt in this solution = 22% × 0.3 = 0.066 gallon

Total amount of salt in the resulting solution = 0.035 + 0.066 = 0.101 gallon

Total volume of the resulting solution = 0.7 + 0.3 = 1.00 gallon

Concentration of the mixture of salt = (0.101/1) = 0.101 = 10.1% = 10% to the nearest percent

Hope this Helps!!!

There are 9 people going on a trip. They purchased coach tickets for $160, and first class tickets for $1180. The total budget t

Savatey [412]

Answer:

Step-by-step explanation:

Given

There are 9 people going on a trip

They purchased coach tickets =$160

first class tickets =$1180

total budget to spend = $4500

Let coach tickets=X

So first class tickets=9-x

160x+1180(9-x)=4500

160+10620-1180x=4500

160x-1180x=4500-10620

-1020x=-6120

X=6120/1020

X=6

So answer

Coach tickets=X=6

First class tickets=(9-x)

=3.

Write an equation in standard form for a line that passes through (2,2) and (0,-3).

asambeis [7]

So,

The standard form is:
y = mx + b

First, we find "m," the slope. Subtract the y-coordinates from each other. Do likewise with the x-coordinates.

2 - -3 = 5
2 - 0 = 2

Slope = 5/2

$y= \frac{5}{2} x+b$

Now, we can substitute the second solution into this equation for x and y and solve for "b."

$-3= \frac{5}{2} *0+b$

$-3= b$

Now we have our complete equation.

$y= \frac{5}{2} x-3$
