Answer:

The system of equations are x+y=64 and x=y+10

Step-by-step explanation:

Given : There are a total of 64 students in a drama club and a yearbook club. The drama club has 10 more students than the yearbook club.

To find : Write a system of linear equations that represents the situation.

Solution :

Let x represent the number of students in the drama club

and y represent the number of students in the yearbook club.

There are a total of 64 students in a drama club and a yearbook club.

i.e. x+y=64 ....(1)

The drama club has 10 more students than the yearbook club.

i.e. x=y+10 ....(2)

Substitute the value of (2) in (1),

y+10+y=64

2y=54

y=\frac{54}{2}

y=27

Substitute in (2),

x=27+10

x=37

Therefore, the system of equations are x+y=64 and x=y+10

Nina [5.8K]

Answer:

Correct choice is D

Step-by-step explanation:

Given the system of two equations:

\left\{\begin{array}{l}4x+y=8\\6x-9y=12\end{array}\right..

Fro mthe first equation

y=8-4x.

Substitute into the second equation 8-4x instead of y:

6x-9(8-4x)=12.

Note that 8-4x=-4x+8, then the second equation will take look

6x-9(-4x+8)=12.

Can someone answer this and please explain it???

It is D because you would do x+6 and would get y so it represents direct proportion

Firdavs [7]

Answer:

0.0239\frac{in^{3}}{min}

Step-by-step explanation:

In order to solve this problem, we must start by drawing a diagram of the cylinder. (See attached picture)

This diagram will help us visualize the problem better.

So we start by determining what data we already know:

Height=6in

Diameter=3.8in

Radius = 1.9 in (because the radius is half the length of the diameter)

The problem also states that the radius will increase on thousandth of an inch every 3 minutes. We can find the velocity at which the radius is increasing with this data:

r'=\frac{1/1000in}{3min}

which yields:

r'=\frac{1}{3000}\frac{in}{min}

with this information we can start solving the problem.

First, the problem wants us to know how fast the volume is increasing, so in order to find that we need to start with the volume formula for a cylinder, which is:

V=\pi r^{2}h

where V is the volumen, r is the radius, h is the height and π is a mathematical constant equal approximately to 3.1416.

Now, the height of the cylinder will not change at any time during the reborning, so we can directly substitute the provided height, so we get:

V=\pi r^{2}(6)

or

V=6 \pi r^{2}

We can now take the derivative to this formula so we get:

\frac{dV}{dt}=2(6)\pi r \frac{dr}{dt}

Which simplifies to:

\frac{dV}{dt}=12\pi r \frac{dr}{dt}

We can now substitute the data provided by the problem to get:

\frac{dV}{dt}=12\pi (1.9) (\frac{1}{3000})

which yields:

\frac{dV}{dt}=0.0239\frac{in^{3}}{min}
