Commutative property of multiplication is two numbers being multiplied either way,example 1x2 = 2x1.
Answer:
The scale factor is 0.25 also written as 1/4
Step-by-step explanation:
1. Find the distance of each leg on the trapezoids
2. Use pathagreum thorum to find the slanted legs
3. Divide the little trapezoid leg to the corresponding big trapezoid leg to find the scale factor because you divide the dialated trapezoids legs by the original trapezoids legs
2÷8 = 0.25
1÷4 = 0.25
2.2360679775 ÷ 8.94427191 = 0.25
2÷8 again = 0.25
So the scale factor is 0.25
Hope this helps! :)
The result correct of this expression is 38
-
In a numeric expression, we first resolve the numbers that are in symbol, such as:
- parentheses, square brackets and braces.
<h3>
</h3>
The signs calculated in order are:
- multiplication/division, addition/subtraction.
<h3>The sign rules are</h3>
- ( - ) = +
+ ( + ) = +
- ( + ) = -
+ ( - ) = -
<h3>Resolution </h3>
So, the answer correct is <u>38</u>
Part A
Answer: 89.50 dollars
---------------------------
Work Shown:
10% = 10/100 = 0.10
10% of $895 = 0.10*895 = 89.50
=====================================================
Part B
Answer: $1350
---------------------------
Work Shown:
x = amount of sales for the week
10% of x = 0.10*x = 0.10x
0.10x = amount Geoff earns in commission
He needs $135, so 0.10x = 135
Divide both sides by 0.10 to isolate x
0.10x = 135
0.10x/0.10 = 135/0.10
x = 1350
He must have $1350 in sales for the week
