First you must add the same numbers together, for instance, you wouldn't add 4y with 4 you have to add it with another number that is just like it, for instance 4y and 9y they are the same, so you can add them. So let's get to the problem now: 5y(2y-3)=(2y-3) 5y*2y=10y (10y-3)=(2y-3) You can do nothing to the other side because there are no numbers, that are the same.

Answer:

20s=m

Step-by-step explanation:

I really don't understand it that well but all that I can is that s can represent students that went on the trip, and each student's ticket cost is 20$, so 20*s=20s, but we are taking m as the total money collected, so we can end up saying that 20s=m, hope u understood :)

Answer:

Part A) The percentage increase was $6.1\%$

Part B) Michael is financially better off this year than last year

Step-by-step explanation:

Part A)

we know that

Using proportion

Let

x-----> the percentage increase

$\frac{100\%}{33,000}=\frac{x\%}{35,000-33,000}\\ \\x=2,000*100\%/33,000\\ \\x=6.1\%$

Part B) Compare the percentage increase with the inflation

$6.1\%>5\%$

The percentage increase is greater than the inflation

therefore

Michael is financially better off this year than last year

Alla [95]

Answer:

The area of a horizontal cross section at a height is $\pi\times(2-\dfrac{y}{7})^2$

Step-by-step explanation:

Given that,

Height = 14 m

Radius = 2 m

Let V be the volume of a right circular cone

We need to calculate the value of R

Using given data

$\dfrac{h}{r}=\dfrac{h-y}{R}$

Put the value into the formula

$\dfrac{14}{2}=\dfrac{14-y}{R}$

$7R=14-y$

$R=2-\dfrac{y}{7}$

We need to calculate the area of a horizontal cross section at a height y

Using formula of area

$A=\pi R^2$

Put the value into the formula

$A=\pi\times(2-\dfrac{y}{7})^2$

Hence, The area of a horizontal cross section at a height is $\pi\times(2-\dfrac{y}{7})^2$
