Kareem inserted 2 quarters into a dryer at a laundromat, and the dryer ran for 12 minutes. At this rate, for how long would the dryer have run if Kareem had inserted 8 quarters instead?

Answers

Answer 1

Answer: 8/2 = x/12
x = 8/2 *12 = 48

Answer 2

Answer: the drier would have run for 48 minutes. it's simple, 2 quarters for 12 minutes, divide 12 by 2. you get 6. multiply 6 by 8, and you get 48...

find the equations of the lines in slope-intercept form which is y=mx+b where m=slope b=y intercept
the choices:
0 solutions: means the lines don't intercect at all, meaning same slope but different y intercept or they ar paralell
1 solution: lines intercect in 1 point
2 solutions: curvy line with a straight line thorugh middle
infinetly solutions: same line

to find slope you do
slope=(y1-y2)/(x1-x2)
first line is
(2,-7)
(0,6)
(x,y)
x1=2
y1=-7
x2=0
y2=6
subsitute
(-7-6)/(2-0)=-13/2
slope=-13/2
subsitute
y=-13/2x+b
subsitute one of the points
(0,6)
x=0
y=6
6=-13/2(0)+b
6=0+b
6=b
y=-13/2+6

now solve for the other equation

(3,0)
(0,-3)
x1=3
y1=0
x2=0
y2=-3
subsitute
(0-(-3))/(3-0)=(0+3)/(3)=3/3=1
y=1x+b
subsitute
(3,0)
x=3
y=0
0=1(3)+b
0=3+b
subtract 3
-3=b
y=x-3

we have the lines
y=-13/2x-6 and
y=x-3
solve for a common solution
y=x-3 and y=-13/2x-6 therefor
x-3=-13/2x-6
add 6 to both sides
x+3=-13/2x
multiply both sides by -2
-2x-6=13x
add 2x to both sides
-6=15x
divide both sides by 15
-2/5=x
subsitute
y=x-3
y=-2/5-3
y=-3 and 2/5 or -17/5
the solution is (-2/5, -17/5)
there is only one solution

the distance around the lake is 0.75 mile.derek ran 0.8 of the distance on monday . how far did he run? the answer is 0.75 * 0.8 how much?Show your work.

Answers

Answer:

0.6 miles

Step-by-step explanation:

We are given that the distance around the lake is 0.75 miles

Derek ran on Monday=0.8 of the distance

We have to find that how far Derek run

0.8 of the distance= $0.8* 0.75$

0.8 of the distance=0.6 miles

Derek ran on Monday=0.6 miles

Hence, Derek run on Monday=0.6 miles

$0.75*0.8= (75)/(100) * (8)/(10) = (75*8)/(100*10) = (600)/(1000) = (6)/(10)=0.6$

It took Alex 2.5 hours to cover a certain route walking at a rate of 3.6 km/h. How long would it take Alex to cover the same route walking at 4.5 km/h?

Answers

It will take Alex 2 hours walking the same route at 4.5 km/h because 3.6km/h times 2.5 hours was 9km, so 9km divided by 4.5km/h is 2 hours.

Answer:

2 hours

Step-by-step explanation:

3.6km/h x 2.5 hours was 9km, so 9km divided by 4.5km/h is 2 hours.
