You have to have a number that ends with three zeros. You have to look at the number formed by the last three digits. If this number smaller or equal to 500, you round down, meaning you just replace the three digits by three zeros, if it is bigger than 500, you round up, meaning you replace the three digits by three zeros and add one to the digit of the thousands.

Here, the last three digits form the number 470 which is smaller than 500 so the nearest thousand of 65470 is 65000.

Find the sum by first finding the equivalent fractions so that both of the fractions have common denominators. Three eighths plu

Iteru [2.4K]

Answer:

thirteen sixteenths

Step-by-step explanation:

Three eighths plus seven sixteenths equals blank

3/8 + 7/16 = ?

= (2*3)+(1*7)/16

= (6+7)/16

= 13/16

13/16 is equivalent to thirteen sixteenths

One side of a square has endpoints (4.7) and (-3,5). What is the perimeter of the square?

Goryan [66]

Answer:

= 4√53 units

that is option(a)

Step-by-step explanation:

all sides of the square are of the same length

so if we get the length if this side, we can calculate its perimeter

there's this formula,

side length between two points, let's say A(x, y) and B(p, q), is equal to 

$\mathsf{ \sqrt{ {(x - p)}^{2} + {(y - q)}^{2} } }$

so here we go,

the same points A and B here are

(4, 7) and (-3, 5)

therefore, side length :-

$= \mathsf{ \sqrt{( {7 - 5})^{2} + {(4 - ( - 3))}^{2} } }$

$= \mathsf{ \sqrt{ {2}^{2} + {7}^{2} } }$

$= \mathsf{ \sqrt{4 + 49} }$

$= \mathsf{\sqrt{53} }$

the side length comes out to be √(53) 

now perimeter of a square is

4 × side length

= 4√53 units
