Answer:

Essentially, they are same thing

Step-by-step explanation:

For example, 3 x 0.4 = 1.2

0.3 x 0.4 = 0.12

The only thing that changes are the amount of numbers behind the decimal. So when multiplying decimals, you just multiply like normal (3 x 4 = 12), then you count the amount of decimal spaces (two) and you take the number (12) and move the decimal place to the left twice. 12.0 would go to 1.2 if multiplying by a tenth.

Answer:

Your friend will win the race due to speed.

Fill in the blanks to complete the area model to solve 6.60 divided by 15 is the same as _ x ? = _ 6.60 = _ hundredths

storchak [24]

Answer:

$15 x = 6.60$

$x = 44\ hundredths$

Step-by-step explanation:

Given

$\frac{6.60}{15}$

Required

Complete the model

[ ] x = 6.60

x = _ hundredths

$\frac{6.60}{15}$

Equate to x

$x = \frac{6.60}{15}$

Multiply both sides by 15

$15 * x = \frac{6.60}{15} * 15$

$15 * x = 6.60$

$15 x = 6.60$

So, we have:

[ ] x = 6.60 =====> $15 x = 6.60$

Recall that:

$x = \frac{6.60}{15}$

$x = 0.44$

This implies that:

$x = 44\ hundredths$

Hence:

x = _ hundredths =====> $x = 44\ hundredths$

Find two consecutive odd integers whose product is 323

Harrizon [31]

Use a let statement
first
let x and x + 2 be the number so you write it like this
let x = the first consecutive integer
let x + 2 = the second consecutive integer

second
x(x+2)=323
x^2 + 2x = 323
-323 -323
x^2 + 2x -323 = 0

third
try to factor -323 so it is 19 and -17
(x + 19) (x - 17) = 0
x = 19
x = -17

The image gives the interval of the values of a data set. It is the difference between the highest number and the lowest number in a dataset. It summarizes all the values of a data with a single number. (3). Since the data has no outlier, the mean will be the best measure of central tendency to describe the score.

Answer:

16.9 m

Step-by-step explanation:

Start with a half a circle. The central angle of a semicircle is 180 deg.

Now subtract 21 deg on each side.

180 - 21 - 21 = 138

The central angle is 138 deg.

The radius is 7 m.
