Calculation:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
then, solving our equation
I = 20 × 0.05 × 2 = 2
I = $ 2.00
The simple interest accumulated
on a principal of $ 20.00
at a rate of 5% per year
for 2 years is $ 2.00.
Answer:
12
Step-by-step explanation:
We can write the following ratio
1:3 (for every student who gets an A 3 gets a b)
We then can write a new ratio
4:x
We can solve this ratio by multiplying the original ratio by 4
4:12
This means that 12 people earned an B
Answer:
210 miles
Step-by-step explanation:
70x3 70mph for 3 hours
3 : 8....can be written as 3/8
12 lbs of apples were sold
apples / oranges : 3/8 = 12/x
this is a proportion, so we cross multiply
(3)(x) = (12)(8)
3x = 96
x = 96/3
x = 32 <=== 32 lbs of oranges
notice that 3/8 = 12/32....these are equivalent fractions....because that is what proportions are, equivalent fractions
Answer:
Distance: 8
Step-by-step explanation:
d = sqrt [(x-x)^2 + (y-y)^2]
d = sqrt [(4-4)^2 + (-4-4)^2]
d = sqrt(0) + (-8)^2
d = sqrt 64 = 8
