Okay, here we have this:

Considering the provided information, we are going to calculate how many minutes does it take per page to print, so we obtain the following:

Then from the statement we are going to calculate the time per page using the following formula:

Time per page = Total time / Total pages

Replacing:

Time per page = 7 minutes / 20 pages

Time per page = 0.35 minutes per pages

Finally we obtain that it take 0.35 minutes per page.

Fencing a horse corral carol has 2400 ft of fencing to fence in a rectangular horse corral. (a) find a function that models the
Vanyuwa [196]

Here it is given that the width is x ft and total length of the fence is 2400 ft .

Let the length be y ft

So we have

2(x+y) =2400
\\
x+y=1200
\\
y = 1200 -x

Let A represents area, and area is the product of length and width .

So we get

A = x y

Substituting the value of y, we will get

A = x (1200-x)= 1200x -x^2

Second part

The area is maximum at the vertex, and vertex is

x = - \frac{1200}{2(-1)} = 600 feet

And

y=1200-x = 1200-600 = 600 feet

And that's the required dimensions .

Marta can vacuum the house in 30 min. It takes her daughter 45 min to vacuum the house. How long would it take them if they
Mamont248 [21]

Answer:

<h2>18mins</h2>

Step-by-step explanation:

This problem is on combined work rate

given that

Marta can vacuum the house in 30 min

then her rate= 1/30

Also, her daughter will take 45 min to vacuum the house

her  daughter's rate will be = 1/45

then the combined work rate is

1/30+1/45=1/T

30+45/30*45=1/T

75/1350= 1/T

1/18=1/T

This means that they will both take 18 minutes working together to vacum a house

Can you please show me the steps and solution to this problem?
ANEK [815]
M = - 7 - 3 / - 2 - 4
m = - 10 / - 6
m = 10/6
m = 5/3

y = 5/3x + c , (4,3)
3 = 5/3(4) + c
12 = 20 + 4c
4c = - 8
c = - 2
y = 5/3x - 2

I need help with these two trigonometry problems.
Ymorist [56]

Answer:

Step-by-step explanation:

For 5 we need to use sine law.

The thing about sine law is that we need to look at the triangle sides that are in front of the angles.

In this case: <B = 30°

the triangle side that is in front of this angle is AC which is 4 cm.

Then we got <C = 61°, and the triangle side in front of it is AB, which is what we need to find.

According to sine law:

\frac{sin B}{AC} = \frac{sin C}{AB}

\frac{sin 30}{4} = \frac{sin 61}{AB}

Notice that you need to be consistent. If you start writing that the angle is in the numerator, it needs to be in the numerator on the other side of the equation.

Solving it would give us:

(AB )(sin 30) = (sin 61)(4)

AB = 6.9969 cm

to the nearest tenth it's 7.0 cm

Question 6:

Wow it's pretty crowded, but they probably want us to use sine law as well. Let's write what we know:

<C  = 12°

<B = 107°

AB = 21 yd

AC = ?

Apply it to the formula: sin(angle) / the triangle side in front of it.

\frac{sin 12}{21} = \frac{sin 107}{AC}\\

(sin 107)(21) = (sin 12)(AC)

AC = 96.59

to the nearest tenth AC = 96.6 yd
