Answer:

(i) commutative property of addition

(ii) associative property of addition

(iii) additive inverse property of addition

(iv) identity element property of addition

(v) multiplicative inverse property of multiplication

Step-by-step explanation:

(i) The commutative property lets you swap the positions of terms in a sum

(ii) The associative property lets you reposition parentheses in a sum

(iii) The additive inverse property tells you the sum of a value and its additive inverse is zero

(iv) The identity element property tells you adding 0 does not change the value

(v) The multiplicative inverse property tells you the product of a value and its multiplicative inverse is 1

The weights of five grapefruits are 7 47 ounces, 7.23 ounces, 6.46 ounces, 7.48 ounces, and 6.81 ounces. Using the

gulaghasi [49]

Answer:

The approximate total weight of the grapefruits, using the clustering estimation technique is B. 35 ounces.

Step-by-step explanation:

We notice that the weights of the grapefruits given are slightly down or above 7, then we will use 7 as our cluster for the estimation, as follows:

Weights

7.47 ⇒ 7

7.23 ⇒ 7

6.46 ⇒ 7

7.48 ⇒ 7

6.81 ⇒ 7

Now we can add up 7 + 7 + 7 + 7 + 7 for the weights of the grapefruits and the approximate total weight is B. 35 ounces.

A young boy let’s out 30 feet of string on his kite. If the angle of elevation from the boy to his kite is 27”, how high is the

const2013 [10]

Answer:

The height of the kite from the ground is 13.617 feet

Step-by-step explanation:

Given as :

The measure of the string = 30 feet

The angle of elevation from the boy to his kite = 27°

Let the height of the kite from ground = H feet

So, From Triangle

Sin angle = $\dfrac{\textrm perpendicular}{\textrm Hypotenuse}$

Or, Sin 27° = $\dfrac{\textrm H}{\textrm 30}$

or, H = 30 × Sin 27°

I.e H = 30 × 0.4539

∴ H = 13.617 feet

Hence the height of the kite from the ground is 13.617 feet Answer
