After 3 months, $3,900 deposited in a savings account with simple interest had grown to a total of $4,017. What was the interest rate?
Answer:
12%
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 12%/100 = 0.12 per year,
then, solving our equation
I = 3900 × 0.12 × 0.25 = 117
I = $ 117.00
The simple interest accumulated
on a principal of $ 3,900.00
at a rate of 12% per year
for 0.25 years is $ 117.00.

Can someone explain step by step how they would solve this.
2(3x-1)-x =2x-11
Answer:
x = - 3
Step-by-step explanation:
Given
2(3x - 1) - x = 2x - 11 ← distribute parenthesis on the left side and simplify
6x - 2 - x = 2x - 11
5x - 2 = 2x - 11 ( subtract 2x from both sides )
3x - 2 = - 11 ( add 2 to both sides )
3x = - 9 ( divide both sides by 3 )
x = - 3

PLS HELP The width of Ben's rectangular family
room is 3 feet less than the length.
The perimeter is 70 feet. What is the
length of the family room?
Answer:
19 feet
Step-by-step explanation:
The perimeter is calculated by multiplying the sum of length and width by 2
width is 3 less than length so if we call the width x the length would be x + 3
2×(x + x + 3) = 4x + 6 and
4x + 6 = 70 subtract 6 from both sides
4x = 64 divide both sides by 4
x = 16
The length is x + 3 so the answer is 19 feet

0.5 g of salt is equal to how many milligrams?
Show all of your calculations.
Answer:
500 mg
Step-by-step explanation:
K H D B D C M (Kilo, Hecto, Deka, Base [meters, grams, etc.] Deci, Centi, Milli)
since you're using grams substitute G for B
K H D G D C M
you have 0.5 grams of salt, which will be G for grams. you want to convert it to milligrams, which is M. you will move the decimal over 3 spots in order to get from G to M, therefore you go from 0.5 grams to 500 milligrams. I hope this is helpful!

What is the standard form equation for a 1/2 line that passes though (-3,-3) and (4,2)
Answer:
y= 5/7x -2.7
Step-by-step explanation:
Y= mx + c (-3,-3) (4,2)
x1 , y1 x2, y2
to find m (gradient)
y^2 - y^1 / x^2 - x^1
2-(-3) / 4 - (-3)
5/7 m = 5/7
take (4,2) and gradient and substitute
2=5/7(4) + c
2=4.7+ c
2-4.7 = c
-2.7 = c
now we have c and m so just put it in the equation
y= 5/7x -2.7

What’s 6.4 rounded to the nearest 10th
Answer:
6.4
Step-by-step explanation:
6.4 is equivalent to 6.40 so it would be closest to 0, leaving it as 6.4.
6.4 is rounded to the nearest 10th as 6.4
The digit in the smallest location is unaffected if it is less than 5 in number. Rounding down is the process of reducing a number to zero after a certain number of digits. The digit in the smallest location is added with +1 if it is bigger than or equal to 5.
After decimal the number is less than 5, so it will remain unchanged and if the number is greater than or equal to 5, then an increment of 1 is introduced.
So, 6.4 rounded to the nearest 10th as 6.4
