Answer:

Let’s organize what they’re asking for.

Subtract the sum of -1250 and 1138 from the sum of 1136 and 1272.

Lets first find the sun if -1250 and 1138:

-1250 + 1138 = -112

Then we’re asked to subtract that sum from the sum of 1136 and 1272. So now let’s find the sum of 1136 and 1272:

1136 + 1272 = 2408

Alright now back to what they’re asking for.

The question asks to subtract the sum of -1250 and 1138 FROM the sum of 1136 and 1272.

We’re subtracting a negative number FROM a positive number, so basically we can turn the negative number into a positive number and we will instead have an addition problem:

2408 - (-112)

The -112 will change to a +112

so now we have an addition problem.

2408 + 112 = 2520

Hello everyone, I have this question. Please help me.
kobusy [5.1K]

Answer:

7 reservoirs

Step-by-step explanation:

1 yards = 3 feet => 3.5 yards = 10.5 feet

To determine how many numbers of reservoirs to reserve 90000, we first need to determine the capacity of each reservoirs (how much liquid one reservoir can contain) - which is equal to the volume.

The formula to calculate the volume of a circular cylinder is:

  - <em>Volume of cylinder = Area of base x Height </em>

<em />

The base of this cylinder is a circle with radius equal to 4 feet. (\pi = 3.14)

=> The are of the base is = \pi *radius^{2} = 3.14 x 4^2 = 50.24 feet square

=> The volume of cylinder = Area of base x Height

=> The volume of one cylinder = 50.24 x 10.5 = 527.52 Cubic foot

We have: 1 cubic foot = 28.317 liters

=> 1 liter = 1/28.317 cubic foot

=> 90000 liters equal to: 90000/28.317 = 3,178.303 cubic foot

The number of reservoirs needed to contain 90000 liters of liquid is:

3,178.303/527.52 = 6.025

=> So that it needs 7 reservoirs to store all 90000 liters of liquid.

Over the summer, Mr. Patel refilled a bird feeder 24 times using 6 cups of seed each time. A bag of seeds holds 32 cups. How man
Illusion [34]

Mr. Patel used 4.5 bags of seed

<em><u>Solution:</u></em>

Given that,

Over the summer, Mr. Patel refilled a bird feeder 24 times using 6 cups of seed each time

A bag of seeds holds 32 cups

1 bag of seed = 32 cups

Given that Patel refilled 24 times using 6 cups of seed each time

<em><u>Then, the number of cups used for the 24 times  is given as:</u></em>

6 \times 24 = 144

<em><u>Now we have to find the bags of seed needed for 144 cups</u></em>

Let "x" be the number of bags of seed for 144 cups

From given,

1 bag of seed = 32 cups

"x" bags of seed = 144 cups

This forms a proportion and we can solve it by cross multiplying

144 \times 1 = 32 \times x\\\\144 = 32x\\\\x = \frac{144}{32}\\\\x = 4.5

Thus 4.5 bags of seed is used by Mr.patel
