Sandra deposited $2,500 into a simple interest account.
She earned $ 75 in interest after 11 year.
Ron deposited $8,000 into an account that has the same interest rate as Sandra’s account.
How much money did Ron earn in interest after 11 year?
Show your work.
Answer:
240$
Step-by-step explanation:
we know that
The simple interest formula is equal to
I=P(rt)
where
I is the Final Interest Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
in this problem we have
Sandra
t = 1 year
I= $75
P= $2,500
r= ?
substitute in the formula above
75=2,500 (r(1))
solve for r
r=75/2,500)
r= 0.03
Convert to percentage form
r= 0.03 * 100 = 3%
Ron
t=1 year
I = ?
P= 8,000
r= 0.03
substitute in the formula of interest
I = 8,000(0.03 *1)
I = $240

2. "The quotient of a number and 4"
Answer:
Step-by-step explanation:
let n= number, the quotient of a number and 4 is
n/4
is f(x) = x^3 - x even, odd, or neither. Explain your answer.
Answer:
odd
Step-by-step explanation:
a function is even when f(-x) =f(x) and a function is odd
when f(-x)= -f(x)
so let's substitute -x into our function
f(-x)= (-x)^3 -(-x)
= -x^3 +1
so, f(-X)= -f(x)
therefore our function is odd

First think of two numbers that have a difference of 8.
Type the LARGER of these numbers below.
Answer:
I thought of 24 and 14 and the larger number is 24
Step-by-step explanation:
24-16=8
The larger number will be "32".
Let the two numbers:
The first number be "32".and,
The second number be "24".By applying the subtraction between the above two numbers, we can find the difference between the numbers.
So,
→ [tex]32-24[/tex]
→ [tex]8[/tex] (difference)
We can see that the greater number between "32" and "24" is "32".
Thus the above answer is right.

7. Find the Value of x. SHOW YOUR WORK OR NO CREDIT!!!!!
Answer:
x=21.9317121994
Step-by-step explanation:
You just look at the half triangle and use the Pythagorean Theorem. One side of the triangle is 9 (half of 18), the other is 20, so you find the hypotenuse.
9²+20²=x²
81+400=x²
481=x²
√481=x
x=21.9317121994
A cylinder has a height of 12 meters and a radius of 5 meters. What is its volume? Use a
3.14 and round your answer to the nearest hundredth.
Answer:
Volume of a Cylinder:
In geometry, a cylinder is a three-dimensional shape with a circular base, a circular top and straight sides. It is the solid figure that you get when you rotate a rectangle about one of its sides. In most cases when we talk about the volume of a cylinder, we are talking about how much liquid it can hold.
The strictly correct way of saying it is "the volume surrounded by a cylinder" - the amount of liquid it holds. But many textbooks simply tell "the volume of a cylinder" to mean the same thing.
