What Is 1,270 rounded to the nearest hundred?

1 answer:

5 0

It would be 1,300. When rounding, you'd need to look at the number to the right of the place you're rounding to. In this case, you're rounding to the hundreds place (the 2), so you look at the number to the right (7). To know if you round up or down use this:

Round down= 0-4
Round up= 5-9

MAXImum [283]

Answer:

C. 13

Step-by-step explanation:

from on online source, the question should be placed as thus:

Of the following integers, which is the closest approximation to (√2 + √5)^2 ?

A. 7

B. 10

C. 13

D. 15

E. 17

This is known as Algebraic expression. So we have to expand to simplify further

using this identity th (a+b)^2 = a^2 + b^2 +2ab

(√2 + √5)^2 =

(√2 + √5)(√2 + √5)

................Expansion of the above

$\sqrt{2}* \sqrt{2} +\sqrt{2}* \sqrt{5} +\sqrt{2} *\sqrt{5}+\sqrt{5} *\sqrt{5}$

2 + 5 + 2√10

~ 2 +5 + 2(3)

Diano4ka-milaya [45]

Answer:

x = -44

Step-by-step explanation:

-8 = x/4 + 3

-8 - 3 = x/4 + 3 - 3

-11 = x/4

-11 x 4 = (x/4) x 4

-44 = x

The value of x is 2 and the length of JK is 4

<h3>How to solve the unknown variables?</h3>

The given parameters from the circle are:

Center = Point S
Segment JK = 8
Segment LK = 2x + 4
Congruent SN = SP = 7

The lines SR and SQ are the radii of the circle P

This means that lines JK and JL are congruent

So, we have:

JK = KL

Substitute LK = 2x + 4 and JK = 4

4 = 2x + 4

Rewrite the above equation as:

2x + 4 = 8

Subtract 4 from both sides

2x + 4 - 4 = 8 - 4

Evaluate the difference

2x = 4

Divide both sides by 2

2x = 4/2

This gives

x = 2

Substitute x = 2 in LK = 2x + 4

LK = 2*2 + 4

Evaluate the product of 2 and 2

LK = 4 + 4

This gives

LK = 8

The point N divides JK into 2 equal segments

So, we have

JN = JK/2

JN= 8/2

JN = 4

Hence, the value of x is 2 and the length of JK is 4
