For this case, we have the expression:

$\frac {b} {c} = \frac {b} {c}$

$c*b=c*b\\\frac{c*b}{c*b}=1\\1=1$

It is an example of identity.

Equality is met, the term that is on the left side of equality is identical to the term on the right side.

Identity property of the sum:

$\frac {b} {c} + 0 = \frac {b} {c}$

Identity property of multiplication:

$\frac {b} {c} * 1 = \frac {b} {c}$

ANswer:

Identity

Tina wants to buy grass seed to cover her whole lawn, except for the pool. The pool is 7/12 m by 3 /14 m. Find the area the gras

eimsori [14]

Answer:

Since Tina wants to buy grass seed to cover her whole lawn, except for the pool, and the pool is 7/12 m by 3/14 m, to find the area the grass seed needs to cover the following calculation must be performed:

It is impossible to determine the area that the grass seed needs to cover, because we do not have the data of the total size of the lawn. Now, you can determine the size of the surface that should not be covered, which is the one that the pool occupies, namely:

7/12 x 3/14 = X

0.583333 x 0.2142 = X

0.1249 = X

Therefore, the grass seed should not cover about 0.1249 square meters.

Factor 21c+24. Write your answer as a product with a whole number greater than 1. use ()

Lera25 [3.4K]

Answer:

The required answer as a product with a whole number greater than 1 will be:

$21c+24=3\left(7c+8\right)$

Step-by-step explanation:

Given the expression

$21c+24$

Determining the factor

$21c+24$

Rewrite 24 as 3 · 8

Rewrite 21 as 3 · 7

so the expression becomes

$21c+24=3\cdot \:\:7c+3\cdot \:\:8$

Factor out the common term 3

$=3\left(7c+8\right)$

Therefore, the required answer as a product with a whole number greater than 1 will be:

$21c+24=3\left(7c+8\right)$

This table shows the number of points two teams scored in five games

mezya [45]

Answer:

2.16

Step-by-step explanation:

The question is on mean absolute deviation

The general formula ,

Mean deviation = sum║x-μ║/N where x is the each individual value, μ is the mean and N is number of values

Team 1

Finding the mean ;

$mean= \frac{51+47+35+48+64}{5} =49$

Points Absolute Deviation from mean

51 2

47 2

35 14

48 1

64 15

Sum 34

Absolute mean deviation = 34/5= 6.8

Team 2

Finding the mean

$mean=\frac{27+55+53+38+41}{5} = 42.8$

Points Absolute deviation from the mean

27 15.8

55 12.2

53 10.2

38 4.8

41 1.8

Sum 44.8

Absolute deviation from the mean = 44.8/5 =8.96

Solution

Difference in mean absolute deviation of the two teams = 8.96-6.8 = 2.16
