Describe the value of the 9 in 926,415 use at least 2 terms from the word list in your explanation

Sedbober [7]

Answer:

The value of 9 in 926,415 is nine hundred thousands

Step-by-step explanation:

* Lets explain how to write a number in the expand form

- Expand form is a way of writing numbers to see the math value

of individual digits

- Ex: the expand form of 23,456 is 20,000 + 3,000 + 400 + 50 + 6

- Place value is the value represented by a digit in a number

- Ex: the place value of 5 in 250 is tens

* Lets solve the problem

- The number is 926,415

- The number formed from 6 digits

- The expand form of the number is:

926,415 = 900,000 + 20,000 + 6,000 + 400 + 10 + 5

- Lets write the place value of each digit

# The place value of 5 is ones

# The place value of 1 is tens

# The place value of 4 is hundreds

# The place value of 6 is thousands

# the place value of 2 is ten thousands

# The place value of 9 is hundred thousands

∴ The place value of 9 in the number is hundred thousands

∴ The value of 9 in 926,415 is nine hundred thousands

The figures below are based on semicircles and squares. Find the perimeter and the area of each shape. Give your answer as a com

irina1246 [14]

Answer:

Part 1) The area of the figure is $A=48\ cm^2$

Part 2) The perimeter of the figure is $P=4(2+3\pi)\ cm$

Step-by-step explanation:

Part 1) Find the area of the figure

we know that

The area of the figure is equal to the area of three squares

$A=3[4^2]=48\ cm^2$

Part 2) Find the perimeter of the figure

we know that

The perimeter of the figure is equal to two times the length side of the square, plus the circumference of six semicircles ( or the circumference of three circles)

Remember that

The circumference of a circle is equal to

$C=\pi D$

where

D is the diameter of the circle

In this problem

$D=4\ cm$

$P=2(4)+3[\pi(4)]=(8+12\pi)\ cm$

simplify

$P=4(2+3\pi)\ cm$

Estimate the sum of 4.27 and 9.91 by first rounding each number to the nearest whole number.

mart [117]

4.27 + 9.91

Round them to the nearest whole number.

4.27 ⇒ 4
9.91 ⇒ 10

Now you can add them up.

4 + 10 = 14
