Answer:
Step-by-step explanation:
This is what i get what i understand from your question .
Kurt earns $7 per hour for doing chores. his goal is to make at least $35 each week
So ,
$7 =per hr
X= unknown hrs
$35= goal
7 x =35
Divide both sides by 7 to get x alone representing hrs.
X= 35/7
X= 5
So 5 hrs per week to make 35 a week.
5×7=35
35=35
Answer:
1. 20 cm^2
2. 40 cm^2
3. 14 cm^2
4 49 cm^2
Step-by-step explanation:
Area of triangle= 1/2(base)*(height)
Area of rectangle= (base)*(height)
1. 1/2(10)(4)=20
2. (8)(5)=40
3.1/2(4)(7)=14
4. (7)(7)=49
Answer:
Option B
Step-by-step explanation:
you should add both the powers that is
2/5 +2/9
28/45
12√18-6√20-3√50-8√45
<em>*Break each radical up into the product of a radical of a perfect square and a second radical*</em>
12(√9*√2)-6(√4*√5)-3(√25*√2)-8(√9*√5)
<em>*Simplify the radicals*</em>
12(3√2)-6(2√5)-3(5√2)-8(3√5)
<em>*Distribute*</em>
36√2-12√5-15√2-24√5
<em>*Combine like terms</em>*
21√2-36√5
Hope this helps!!
