Hey there!
This situation can be represented by the following equation:
y = 20 + 20x
This is because she starts without any time passing with 20 pounds of cans and collects 20 more pounds every week.
So when x = 0, y = 20.
The variable y is the number of pounds of cans collected, while x is the number of weeks passed.
If we want to find the number of pounds of cans she has after 10 weeks, we have to substitute x = 10 like this:
y = 20 + 20(10)
Multiply 20 x 10.
y = 20 + 200
Add 20 + 200.
y = 220
Your answer is 220 pounds, the second option shown!
Hope this helps!
Answer:
Step-by-step explanation:
The area of a triangle is
A=bh/2 where b=base and h=height. So we first have to solve for h
8^2+h^2=12^2
h^2=12^2-8^2
h^2=144-64
h^2=80
h=(80)^(1/2), now we can find the area
A=8(80^(1/2))/2
A=4(80^(1/2)
A=35.78cm
Yes. Kevin can carry the basket 5 ft. Rachel can carry it 3 feet more than Kevin (5+3=8). Daniel can carry the basket half the length of Rachel (8/2=4). The total distance they can carry the basket is 5+8+4=17. 17 is greater than 15, so yes they can carry it 15 feet.
Answer:
She should leave a total of $78.
Step-by-step explanation:
To find this, we first need to find the tip amount. We can do this by multiplying the total by the tip percentage.
$65 * 20% = $13
Now that we have that, we need to add it to the cost.
$65 + $13 = $78
