Kim deposited $1,422 into a savings account. After 5 years, she had a total of $1,635.30 in her account. What is the interest rate?
Answer:
42.66%
Step-by-step explanation:
subtract the amount of money from after and before: 1,635.30 - 1,422 = 213.3
divide the amount of money gained by the years: 213.3/5 = 42.66
What part of 1hr and 40 min is 25 min as a fraction?
Step-by-step explanation:
1 hour = 60 minutes
40 minutes out of an hour can be written as: 40/60
Fraction = 40/60
= (2 × 30) / (3 × 20)
Canceling out common factors of numerator and denominator, we get 2/3
Therefore, 40 minutes is 2/3 of an hour.

3
of the peach pie was eaten
What is the total amount of Luis' pies that were left over?
Answer:
2 1/4 pies
Step-by-step explanation:
Find out how much pie was leftover from each pie:
Apple pie: 3/4, 4 - 3 = 1, 1/4
Blackberry: 1/2, 2 - 1 = 1, 1/2
Blueberry: 1/8, 8 - 1 = 7, 7/8
Cherry: 5/8, 8 - 5 = 3, 3/8
Peach: 3/4, 4 - 3 = 1, 1/4
There are 1/4, 1/2, 7/8, 3/8, and 1/4 pies left. The LCD if these numbers is 8, since 2*4 = 8, 4*2 = 8, and 8*1 = 8
1/4 = 2/8
1/2 = 4/8
7/8 = 7/8
3/8 = 3/8
1/4 = 2/8
2 + 4 + 7 + 3 + 2 = 18, so 18/8 pies, or 2 2/8, or 2 1/4
if 3x2+3y2=42 and xy= -15, find the value of (x-y)2
Answer:
44
Step-by-step explanation:
x^2 + y^2 = 14
(x-y)^2 x^2 + y^2 - 2xy = 14 -2 * (-15) = 44

The two dot plots below show the heights of some sixth graders and some seventh graders:
Two dot plots are shown one below the other. The title for the top dot plot is Sixth Graders and the title for the bottom plot is Seventh Graders. Below the line for each dot plot is written Height followed by inches in parentheses. There are markings from 52 to 57 on the top line and the bottom line at intervals of one. For the top line there are 2 dots above the first mark, 1 dot above the second mark, 1 dot above the third mark and 2 dots above the fourth mark. For the bottom line, there is 1 dot for the first mark, there are 3 dots above the second mark, 2 dots above the third mark.
The mean absolute deviation (MAD) for the first set of data is 1.2 and the MAD for the second set of data is 0.6. Approximately how many times the variability in the heights of the seventh graders is the variability in the heights of the sixth graders? (Round all values to the tenths place.) (5 points)

If Madi deposits $40 more in her bank account this week, she'll then have $162.
How much money does he have to start out with this week?
Choose the equation that correctly models this situation.
m + 162 = 40
40m = 162
m - 40 = 162
m + 40 = 162

Barbara wants to restore her'66 Mustang in 4 years. She puts ... He deposits $100 ... b. Write the future value function if x represents the number of weeks.
Step-by-step explanation: how are you?
Answer:
M + 40 = 162
Step-by-step explanation:
if M is the original amount of money Madi has and she adds 40, Then she would have 162.
What is the value of M ?

The surface area of a lantern shaped like a sphere is 452.16 square inches. What is the approximate volume of the lantern? Use 3.14 for π. Round your answer to the nearest hundredth.
A.150.72 in.3
B.452.16 in.3
C904.32 in.3
D.5,425.92 in.3
The approximate volume of the lantern is, V = 904.32 in³
How can the surface area of this sphere can be expressed ?The concept here is using the surface area formula which is
A = Area = (4 π r² )
V= Volume =( 4/3 π r³)
Then , We get;
A / V = 3 / r
Also, r = √A / 4π
Then we can substitute the values as
π = 3.14
r = √452.16 / 4×3.14
r = √36
r = 6
Hence, We get;
V = 4/3 πr³
V = 4/3 × 3.14 × 6³
V = 904.32 in³

Answer:
d = -10/7 = -1 3/7
that is the answer for number 1.
For number 2. the answer is U = 13/4 = 3 1/4 = 3.25
step by step explanation
multiply both sides of the equation by 4 the least common multiple of 2,4
2 (5 x 2 + 1) -4 u = 9 then multiply 5 and 2 to get 10
2 (10 + 1) -4u =9
then add 10 and one to get 11
2 x 11 -4u =9
then multiply two and 11 to get 22
22 -4u = 9
then subtract 22 from both sides
subtract 22 - 9 to get -13
-4u = -13 then undo multiplication by dividing both sides divide both sides by 4-13 / -4 can be divided by positive 13/4
your answer is 13/4
