Round 354,605 to nearest thousand

Answers

Answer

355,000.

Explanation

When rounding numbers we count digits from the right to the left. The first place value from the right is once followed by tens, hundreds, thousands etc.

354,605

5 ⇒ ones

0 ⇒ tens

6 ⇒ hundreds

4 ⇒ thousands

354,605 to the nearest thousands is 355,000.

Answer:

$355,000$

Step-by-step explanation:

We have been given an number $354,605$ . We are asked to round our given number to the nearest thousand.

Upon looking at our given number we can see that the value of the 1st dropped figure that is at hundreds place value, is greater than 5.

Since hundreds place value is 6 or we can see that last three digits are 605, therefore, we will round up our number to nearest thousand as:

$354,605\approx 355,000$

aisha used six boards on each of the birdhouses she made .which experssion represents the total number of boards she would need to make n birdhouse

Answers

Well normally you would have to know the amount of birdhouses that she made. But if not, then it would be multiplying 6 times the number of n the amount of birdhouses that she made. Not sure if this is making sense. but if there are 6 boards for N (each of the bird houses) then the answer would just be 6n which is 6 times n

L=P+2G over K Solve for G?

Answers

L = P + 2G / K

Multiply both sides by K to get rid of the denominator

KL = P + 2G

Subtract P from both sides

KL - P = 2G

Divide each side by 2

KL - P / 2 = G

G = KL - P / 2

Hi Brand

L=P+(2G)/k

Multiply both sides by K

KL= KP+2G

Flip the equation

KP+2G=KL

add -KP to both sides

KP+2G-KP=KL-KP

2G=KL-KP

Divide both sides by 2

2G/2= (KL-KP)/2

G= 1/2 KL + -1/2 KP
