Find the interest earned in 1 year and divide it by 12 (number of months per year)
simple interest=principal times rate times time
so we have 1250 principal (amount invested)
rate is 5% or 0.05
time is 1 year
in 1 year, he earns 1250 times 0.05 times 1 or $62.5 per year
divide by 12
62.5/12=5.2083333333333333333333333333333
earns about $5.21 per month in interest
Answer:
median is 90
Step-by-step explanation:
75, 88, 92, 100
(88+92)/2 = <u>90</u>
Answer:
13 or 13.125 you have to look at your notes to see which it is. Personally I would take 13. Try that first.
Step-by-step explanation:
Be careful how you interpret this question. It reads like this.
3:8 :: x:35
In other words, the 8 and 35 females goes together.
Set this up as a proportion
3/8 = x / 35 Cross multiply
3*35 = 8x Combine the left
105 = 8x Switch
8x = 105 Divide by 8
x = 105 / 8 get the answer
x = 13.125 You cannot have 1/8 of a person. So what are you going to do?
You have to round down. x = 13. How close is this
13/35 = 0.371 as apposed to 0.375 which is what 3/8 is.
They are the same slope
they are negative inversees (they multily to get -1)
2
-1/2
use the square viewer (on TI)
The relationship between the slopes of two lines that are parallel is they are the same.
The relationship between the slopes of two lines that are perpendicular is they are negative inverses of each other (they multiply to -1).
A line that is parallel to a line whose slope is 2 has slope 2.
A line that is perpendicular to a line whose slope is 2 has slope -1/2.
What must be done to make the graphs of two perpendicular lines appear
to intersect at right angles when they are graphed using a graphing

Answer:
Step-by-step explanation:
Brand A: 3.89/72= 0.054 for each fork --> round 0.05
Brand B: 6.62/96 = 0.0689 for each fork--> round up to 0.07
by rounding, brand A is the better buy
