A copy machine makes

1 answer:

7 0

This problem can be represented in a formula with fractions. To make it more simple, we are converting 5m30s to just pure seconds, which = 154 copies in 330 seconds.

You set up the formula like this: 154/330 = x/60. (it is x/60 because you want to know the x amount of copies per 60 seconds)

Cross multiply, you get 330x = 9240. Divide both sides by 330, you get:

x = 28 copies.

The final answer is 28 copies per minute

What is the area of the figure in the picture above?

jek_recluse [69]

The square area is 6*6=36
For the two triangles, the area is base*height/2 = 6*3 = 18.
So the total area is 18+36+18=72

He can either pay a $150 joining fee and a $10 monthly fee or he can pay a $50 joining fee and a $30 monthly fee. On what month

larisa86 [58]

Answer:it will take 5 months for the cumulative costs of the plans to be equal and the total cos is $200

Step-by-step explanation:

Let x represent the number of months that for which the cumulative costs of the plans will be equal.

Let y represent the total cost of using plan A for x months.

Let z represent the total cost of using plan B for x months.

He can either pay a $150 joining fee and a $10 monthly fee. This means that the total cost of using plan A would be

y = 150 + 10x

For plan B, he can pay a $50 joining fee and a $30 monthly fee. This means that the total cost of using plan B would be

y = 50 + 30x

To determine the number of hours for which the cumulative costs of the plans will be equal, we would equate y to z. It becomes

150 + 10x = 50 + 30x

30x - 10x = 150 - 50

20x = 100

x = 100/20 = 5 months

The total cost would be

150 + 10 × 5 = 150 + 50 = $200

HELP ASAP A vector starts at point (-3, 4) and ends at point (6, -3). What is the magnitude of the vector? Answer to two decimal

balu736 [363]

The magnitude of the vector to two decimal places is 11.40 units

The formula for calculating the magnitude of the vector is expressed as:

$D=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2 }$

Given the coordinate points (-3, 4) and (6, -3)

$D=\sqrt{(-3-4)^2+(6+3)^2 }\\D=\sqrt{(-7)^2+9^2}\\D=\sqrt{49+81}\\D=\sqrt{130}\\D= 11.40$

Hence the magnitude of the vector to two decimal places is 11.40 units
