Well, in two tons there are 4,000 pounds. In every crate, you can carry 80 pounds.

4,000/80=50

A ton is 2000 pounds, so 2 tons would be 4000 pounds. 4000 pounds divided by 80 (because of there being 8, 10 pound bags per box) so the correct answer would be 50

Monique randomly surveyed 30 students from

Naily [24]

Answer:

522

Step-by-step explanation:

Find the percent of students in her class that have a dog or cat:

Set up a proportion: $\frac{18}{30} = \frac{x}{100}$
Cross multiply, then divide: 18 × 100 = 1800, 1800 ÷ 30 = 60
So, 60% have a dog or cat

Find 60% of the total amount of students in Monique's school:

60% of 870 = $\frac{60}{100}$ × $\frac{870}{1}$
$\frac{60}{100}$ × $\frac{870}{1} = \frac{52200}{100}$
$\frac{52200}{100} = \frac{522}{1} = 522$

I hope this helps!

PLEASE HELP WILL GIVE BRAINLIEST the number of students at north middle school is 1240 and is decreasing by 25 students per year

Nikolay [14]

Answer:

-88

Step-by-step explanation:

Let N(x) be the number of students at NMS for a certain number of years.

Let S(x) be the number of students at SMS for a certain number of years.

Let x be the number of years.

N(x)=1240-25x

S(x)=800-30x

When # of students is equal, N(x)=S(x). Therefore, we are looking for the value of x (# of years) when 1240-25x=800-30x

Subtract 1240 from each side

-25x=-440-30x

Add 30x

5x=-400

x=-88 years

use the graph to write a linear function that relates y to x when the slope is 4/3 and the yint is 2

lora16 [44]

Answer:

y = 4/3x +2

Step-by-step explanation:

The graph crosses the y-axis at y=2, so that is the y-intercept.

The points have a rise of 4 units for each horizontal run of 3 units, so the slope is ...

m = rise/run = 4/3

The slope-intercept equation for the line is ...

y = mx +b . . . . . . line with slope m and y-intercept b

y = 4/3x +2
