A school donated 283,482 cans of soup to a food kitchen if the food kitchen used 20000 cans of soup each month how many months c

Alona [7]

Answer:

14 months

Step-by-step explanation:

Here we are interested in calculating the number of months it will take the food kitchen to exhaust the 283,482 soup cans donated to it by a school of it uses 20,000 cans of soup.

This is pretty straightforward, trust me!

What needs to be done here is to simply divide the total number of soup cans donated by the school by the number of soup cans used by the food kitchen each month.

Mathematically, that would be;

283,482/20,000

A calculator would work here? Right?

And the division equals 14.1741

And to the nearest whole number, that is 14.

And yes there would surely be some left, carried over to the 15th month, but would that sustain them for the month? No

point C (4, -3) is translated left 3 and up 5 and is then dilated by a scale factor of 4. What are the coordinates of C'?

sergeinik [125]

Answer: (4, 8)

Step-by-step explanation:

When you translate something to the left you need to subtract the amount you moved left from the original x input

1. Subtract 3 from the coordinates x input

4 - 3 = 1

When you translate something up you need to add the amount you moved up to the original y output

2. Add 5 to the coordinates y output

-3 + 5 = 2

When done translating to the left and up your coordinate is now (1, 2)

When dialating something you need to multiply the scale factor in which you dialated the coordinate to both the x input and y output

3. Multiply 4 to the x input and y output of your newley translated coordinate

1 × 4 = 4 (x input)

2 × 4 = 8 (y output)

So now your final coordinate for C' is (4, 8)!

Hope this helps :)

Use the Pythagorean Theorem to find the distance

docker41 [41]

Answer:

About 10.05

Step-by-step explanation:

The change in x is 1, so the bottom line is a length of 1. The change in y is 10, so the right line is 10. Since a^2+b^2=c^2, 1^2+10^2=101, and the square root of 101 is about 10.05.

It takes 23 minutes for 6 people to paint 6 walls. How many minutes does it take 9 people to paint 7 walls?

bogdanovich [222]

For this problem you need to first find a unit rate (rate = 1/time), how fast per minute can 1 person paint a wall?

Once you have this rate you can find how many minutes it takes to do any number of walls with any number of people.

Lets call this unit rate 'r'. Number of people = n, Number of walls = w.
By multiplying the unit rate by 'n', you get the speed n people can paint a wall. Example, if it takes 4 min to paint 1 wall the unit rate = 1/4. The speed for 8 people is 8*(1/4) = 2 walls per minute. Time = 1/rate. So 2 walls per minute = 1/2 min per wall. Now multiply time by w. If there are 10 walls, (1/2)*10 = 5 , It takes 8 people 5 min to paint 10 walls.

The general formula is:
$t = \frac{w}{n*r} \\ \\ r = \frac{w}{n*t}$

Now apply to given problem:
Time = 23 min, n = 6, w = 6
Solve for unit rate 'r'
$r = \frac{6}{6*23} = \frac{1}{23}$
Find time, given
n = 9, w = 7
$t = \frac{7}{9*(1/23)} = \frac{7*23}{9} = 17.89$
Answer:
it takes 17.89 min or 17 min 53 sec
