It will take her 8 weeks because if the bike is 245$ and she has 125$, 245-125= 120 and 15÷120= 8 because 15 goes in to 120 8 times
0,-3
To work this out I would use the midpoint formula. (x1+x2)/2 , (y1+y2)/2
Therefore, (3+-9)/2 , (-4+0)/2
= -6/2. , -4/2
= -3 , -2
Now we know the half way point from AB, now we will use the same formula but instead of point B we will substitue the midpoint to work out the 1/4 point
Therefore, (3+-3)/2, (-4+-2)/2
=. 0/2, -6/2
=. 0, -3
Therfore the 1/4 way point from AB is 0,-3
Divide 25 by 1 2/3 or 1.66 and then round down to get 15
Answer:
Step-by-step explanation:
If the pool has a rectangular shape then its volume can be written as:
V = Width * Length * Depth
Let's call:
w = width
l = length
d = depth.
So we know from the statement of the problem that:
(5 feet more than 5 times the depth)
(50 feet more than 5 times the depth)
Then, the volume can be written according to the depth as:
So let's give each letter a variable
If b is 90% of c that means:
b=.9c
If a is 30% of C that means:
a=.3b
So take that second equation (a=.3b), and use the first equation to plug in for b. We get:
a=.3(.9c)
.3*.9=.27 which means:
a=.27c
.27=27%
ANSWER:
a is 27% of c
If you want to check you could give c a number.
Let's say c=100
If b is 90% of c that means . 9(100)=b
.9(100)=90=b
To get a, multiply b by 30%
.3(90)=27=a
It checks out because 27 is 27% of 100
