A copy machine can print 480 copies every 4 minutes. How many copies can it print in 10 minutes

tensa zangetsu [6.8K]

Answer:

1200 copies

Step-by-step explanation:

In order to find how many copies can be printed in 10 minutes, first we need to find how many copies the machine can print in one minute. Let that be x.

480= 4x

Divide both sides by 4

120=x

Now, we need to multiply that by how many minutes we need to find.

120* 10= 1200

Thus, the machine can print 1200 copies in 10 minutes.

Suppose that triangle ABC is a right triangle with a right angle at C and hypotenuse C. Also note that a is the length of the si

gavmur [86]

Answer:

The value of a is 7.4833. The value of $A=29.9262^0$ and $B=60.0735^0$ .

Step-by-step explanation:

Consider the provided information.

The required figure is shown below:

We need to find the value of a.

Calculate the value of a by using Pythagorean theorem.

$a^2+b^2=c^2$

$a^2+(13)^2=(15)^2$

$a^2=225-169$

$a^2=56$

$a=7.4833$

Hence, the value of a is 7.4833.

Now find the value of angle A as shown:

$\sin A=\frac{a}{c}$

$\sin A=\frac{7.4833}{15}$

$A=sin^{-1}(0.4989)$

$A=29.9262^0$

Find the value of angle B as shown:

$\sin B=\frac{b}{c}$

$\sin B=\frac{13}{15}$

$B=sin^{-1}(0.8667)$

$B=60.0735^0$

Hence, the value of $A=29.9262^0$ and $B=60.0735^0$ .

What is 3.2 x 10^-4 m/h in centimeters per second?

Iteru [2.4K]

$1m=100cm\\h=3600s\\\\3.2\times10^{-4}\ m/h=3.2\times10^{-4}\times\frac{100}{3600}\ cm/s\\\\=3.2\times10^{-4}\times\frac{1}{36}\ m/s=\frac{3.2}{36}\times10^{-4}\ m/s\\\\=0.888...\times10^{-4}\ m/s=\boxed{8.889\times10^{-5}\ m/s}\\\\Answer:\boxed{b)}$
