Estimate the sum of 703 + 620

Answers

Answer 1

Answer:

The sum of 703 + 620 will be 1323.

What is summation?

A summation, also abbreviated as a sum, is the outcome of adding two or more numbers or quantities. Here are always an integer number of terms in a summation. There could be only two terms, but there could be one hundred, thousand, or a million. There are summations with an infinite set of parameters.

In another word, the summation is to add or subtract any two or more terms by doing that operation we will get a new result which could be big or small depending upon the number.

Given the sum of 703 + 620

703 = 700 + 3

620 = 600 + 20

So,

703 + 620 = (700 + 3) + (600 + 20)

703 + 620 = (700 + 600) + (3 + 20)

703 + 620 = 1300 + 23

703 + 620 = 1323

Hence "The sum of 703 + 620 will be 1323".

Answer 2

Answer: When you estimate, you round each number, the add.
We round them to
700+620, which is 1320
So our non estimated answer is 1323
But our estimated answer is 1320

Solve the equation for the letter L: V = LWH

Answers

$LWH=V\qquad\text{divide both sides by}\ WH\neq0\n\n\boxed{L=(V)/(WH)}$

Answer:

L = V / WH

Step-by-step explanation:

Solve for L: V = LWH

To solve, all you have to do is get L on its own on one side.

Because the only operation used in this equation is multiplication, only one operation is needed to solve it: division. Just divide both sides by WH to isolate L.

V / WH = LWH / WH

V / WH = L

The NYC Parks Department is designing a rectangular athletic field for a new park in Brooklyn. The width of the field needs to be 10 feet shorter than the length, and the perimeter of the field needs to be 80 feet. What is the length of the new field?

Answers

Answer:

Length = 25feets

Step-by-step explanation:

Let the length l = x

Width w = x - 10

Perimeter = 80

And Perimeter = 2(l + w)

:- 80 = 2{x + (x - 10)}

80 = 2{x + x - 10}

80 = 2(2x - 10)

80 = 4x - 20

4x = 80 + 20

4x = 100

x = 100/4

x = 25ft
