Kelli Rae invested $220,000 in a savings account with simple interest. After 10 years, Kelli Rae had $250,000. What is the interest rate on this account?
Answer:
Interest rate = 1.363% (Approx.)
Step-by-step explanation:
Given:
Amount invested P = $220,000
Amount after 10 year = $250,000
Number of year = 10 year
Find:
Interest rate
Computation:
A = P + I
Amount of interest = $250,000 - $220,000
⇒ Amount of interest = $30,000
Amount of interest = PRT
⇒ 30,000 = (220,000)(R)(10)
⇒ 30,000 = (2,200,000)(R)
⇒ R = 0.013636
Interest rate = 1.363% (Approx.)

Thanks
Answer:
(a+b)(a+b)
=a^2 + ab + ab + b^2
=a^2 + 2ab + b^2
Answer:
(a+b)² = ( a +b ) (a + b )
= a² + b² + 2ab
Lindsey bought a picnic basket originally priced at $40 but on sale for 50% off. After 10% sales tax, what was the total cost?
Answer:
$30
Step-by-step explanation:
Given data
Origianal price= $40
discount= 50%
Tax= 10%
Let us find the amount of the discount and tax
Discount
=50/100*40
=0.5*40
=$20
Tax
=10/100*40
=0.1*40
=$4
Hence the total cost is
=40-20+10
=$30

Given that x^6 = 64, which of the following could be the value of 9x^2 + 3x ?
Answer:
42,-42
Step-by-step explanation:
We first solve for x from x^6 = 64, by taking the root of both sides, and we get x = 2,-2
We then plug in both of the x values and get 42,-42
PS: That should be the right answer but you didn't include the possible answers, and I somehow also got 30 when plugging in -2, but just try it yourself to be safe.
if you can please show work or explain your answer

Adina has a total of $1.65 in nickels and dimes. The number of dimes is 6 more than the number of nickels. How many coins are there of each type?
Choose the correct system of equations needed to solve this problem.
A
0.10d+0.05n=60.10d+0.05n=60.10d+0.05n=6
n+d=1.65n+d=1.65n+d=1.65
B
d=n+6d=n+6d=n+6
0.05n+0.10d=1.650.05n+0.10d=1.650.05n+0.10d=1.65
C
n=d+6n=d+6n=d+6
0.10d+0.05n=1.650.10d+0.05n=1.650.10d+0.05n=1.65
D
n=d+6n=d+6n=d+6
0.05n+0.10d=1.650.05n+0.10d=1.650.05n+0.10d=1.65
Answer:
C
Step-by-step explanation:
If you divide 1.65 by 6 you'll get 0.275 so then you'll add d+6n to get d+6 and then you'll solve the question for 6n and you'll get 1.65
please help thank youu!!
A kite has A = 120 cm2 and d1 = 16 cm. Identify the length of d2.
Answer:
d₂ = 15 cm
Step-by-step explanation:
The area (A) of a kite is calculated as
A = [tex]\frac{1}{2}[/tex] d₁d₂
Here A = 120, d₁ = 16 , then
[tex]\frac{1}{2}[/tex] × 16 × d₂ = 120
8d₂ = 120 ( divide both sides by 8 )
d₂ = 15 cm

John travels 16m ^2 +100 miles. /since he can only travel 8m +10 mph, it takes him 2m hours to make the trip. Solve for m
Answer:
m = 5
Step-by-step explanation:
distance traveled D= 16m^2+100 miles
speed, S= 8m+10 mph
time taken, T = 2m hours
We know that D = S×T
⇒ 16m^2+100 = (8m+10)× 2m
⇒ 16m^2+100 = 16m^2+ 20m
⇒ 20m = 100
⇒ m = 5
Therefore, the value of m is 5
