Katherine invested $86,000 in an account paying an interest rate of 52%
compounded daily. Michael invested $86,000 in an account paying an interest rate of
5% compounded continuously. After 13 years, how much more money would
Katherine have in her account than Michael, to the nearest dollar?
Answers
Answer: $4,331
Step-by-step explanation:
I will assume that the question meant 5.2% not 52% as this is quite excessive.
Katherine after 13 years.
Convert the variables;
n = 13 years = 13 * 365 = 4,745 days
r = 5.2% = 5.2/365 = 5.2/365%
Future value = P * ( 1 + r)^n
= 86,000 * (1 + 5.2/365%)⁴⁷⁴⁵
= $169,068
Michael after 13 years;
If compounded continuously, the formula is;
Future value = Pe^rt
= 86,000 * e⁰.⁰⁵ ˣ ¹³
= $164,737
Difference = 169,068 - 164,737
= $4,331

19(2m−16)=13(2m+4) (pls helppp)
Answers
Answer:
Simplified this is -304 + 38m = 52 + 26m
m in the equation is 29 2/3
Step-by-step explanation:
Reorder the terms:
19(-16 + 2m) = 13(2m + 4)
(-16 * 19 + 2m * 19) = 13(2m + 4)
(-304 + 38m) = 13(2m + 4)
Reorder the terms:
-304 + 38m = 13(4 + 2m)
-304 + 38m = (4 * 13 + 2m * 13)
-304 + 38m = (52 + 26m)
Simplfied answer:
-304 + 38m = 52 + 26m
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '-26m' to each side of the equation.
-304 + 38m + -26m = 52 + 26m + -26m
Combine like terms: 38m + -26m = 12m
-304 + 12m = 52 + 26m + -26m
Combine like terms: 26m + -26m = 0
-304 + 12m = 52 + 0
-304 + 12m = 52
Add '304' to each side of the equation.
-304 + 304 + 12m = 52 + 304
Combine like terms: -304 + 304 = 0
0 + 12m = 52 + 304
12m = 52 + 304
Combine like terms: 52 + 304 = 356
12m = 356
Divide each side by '12'.
m = 29.66666667
Simplifying
m = 29.66666667 = 29 2/3

Jose has 4 5/6 pounds of chicken, 3 1/3 pounds of steaks and 5 5/6 pounds of hamburgers to put on the grill. How many pounds of meat does he have for the barbecue
Answers
Answer:
14 pounds of meat
Step-by-step explanation:
Jose has 4 5/6 pounds of chicken, 3 1/3 pounds of steaks and 5 5/6 pounds of hamburgers to put on the grill. How many pounds of meat does he have for the barbecue
We have to find the sum of the the total pounds of meat.
This is calculated as:
4 5/6 pounds + 3 1/3 pounds + 5 5/6 pounds
[(4 + 3 + 5) + (5/6 + 1/3 + 5/6)] pounds
The Lowest Common Denominator
= 6
Hence:
[12 + (5 + 2 + 5 /6)] pounds
= 12 + 12/6
= 12 + 2
= 14 pounds of meat
Hence, Jose has 14 pounds of meat

A biologist recorded a count of 348 bacteria present in a culture after 5 minutes and 1088 bacteria present after 20 minutes. To the nearest whole number, what was the initial population ?
Answers
Answer:
The initial bacteria population is 238
Step-by-step explanation:
Let us have the increase as an exponential equation
P(t) = I(1 + r)^t
where P(t) is the count at a particular time
r is the percentage increase
I is the initial population
t is the time
So for 5 minutes, we have
348 = I(1 + r)^5
For 20 minutes
1088 = I(1 + r)^20
Divide the second equation by the first
1088/348 = I(1 + r)^20/I(1 + r)^5
3.13 = (1 + r)^15
Take the ln of both sides
ln 3.13 = 15 ln (1 + r)
ln 3.13/15 = ln (1 + r)
0.0761 = ln (1 + r)
1 + r = e^0.0761
1 + r = 1.079
r = 1.079-1
r = 0.079 which is 7.9%
So per minute. we have an increase of 7.9%
So let’s get I by substituting
From;
348 = I(1 + 0.079)^5
348/1.079^5 = I
I = 237.9 which is 238 to the nearest whole number

For a field trip, a highschool want to buy T-shirts and sweatshirts. The expression px + 29y repersents the cost of buying x T-shirts and y sweatshirts from the store. If each sweatshirt cost $17 more than a T-shirt what is the value of p ?
Answers
Answer:
The value of p is $12.
Step-by-step explanation:
Given;
c = px + 29y ,,,,,,,,,,,,,,,,,,, (1)
Where;
c = cost of buying x T-shirts and y sweatshirts from the store
p = price of one or each T-shirt = ?
x = number of T-shirts bought
29 = price of one or each sweatshirt
y = number of sweatshirt bought
Based on the above breakdown, if each sweatshirt cost $17 more than a T-shirt, the value of p can be calculated as follows:
29 = p + 17
p = 29 - 17
p = 12
Therefore, the value of p is $12.
Additional note:
Note that this is not part of the question but it is just an example to make you understand the question better.
If we assume that 10 T-shirts and 10 sweatshirts are bought from the store, we can use equation (1) above to calculate the cost as follows:
Where;
c = cost of buying x T-shirts and y sweatshirts from the store = ?
p = price of one or each T-shirt = 12
x = number of T-shirts bought = 10
29 = price of one or each sweatshirt
y = number of sweatshirt bought = 10
Substituting the values into equation (1), we have:
c = (12 * 10) + (29 * 10)
c = 120 + 290
c = 410
Therefore, the cost of of buying 10 T-shirts and 10 sweatshirts from the store will be $410.

Referring to the line plot the most common size is 1-3/4 cups. Since there are 5 of them we multiply by the value 1.75 (the equivalent of 1-3/4).
5 x 1.75 = 8.75 cups, or 8-3/4 cups
