Answer:
500 is the number
Step-by-step explanation:
A savings account starts with $181.25. After 7 years of continuous compounding at an interest rate, r, the account has $1450. What is the interest rate percentage? Round the answer to the nearest hundredth.
Rate of interest by which amount $181.25 becomes $1450 in 7 years by continuous compounding will be 29.71%.
Rule for the continuous compounding: Expression for the final amount comounded continuously is given by,
Final amount = [tex]Pe^{rt}[/tex]
Here, P = Principal amount
r = Rate of interest
t = Duration of investment
Given in the question,
P = $181.25
t = 7 years
Final amount = $1450
Substitute these values in the expression,
[tex]1450=181.25e^{7r}[/tex]
[tex]e^{7r}=8[/tex]
[tex]\text{ln}(e)^{7r}=\text{ln}(8)[/tex]
[tex]7r=2.07944[/tex]
[tex]r=0.2971[/tex]
[tex]r=29.71\%[/tex]
Therefore, rate of intereset for the investment is 29.71%.

What would be the first five terms of sequence whose first term is 1 and has a common ratio of 1/3?
Answer:
Step-by-step explanation:
This is a geometric sequence; we know that because of the words "common ratio." The general formula for a geometric sequence is
a(n) = a(1)*r^(n - 1), where r is the common ratio.
Here, a(1) = 1, r = 1/3, and so
a(1) = 1 (given)
a(2) = 1/3 (this is a(1) multiplied by 1/3)
a(3) = 1/9 (this is a(2) multiplied by 1/3)
a(4) = 1/27
a(5) = 1/81

Answer:
c=45 +679 =6y=8h
Step-by-step explanation:
Given that triangle ABC has angle ABC = 90 degrees, AB = 6 cm and BC = 9 cm. Calculate the length of AC in cm to 1 decimal place
Answer:
AC = 6.7
Step-by-step explanation:
If this is a 90 degree triangle which I am assuming it is you would the Pythagorean theorem c^2 = a^2 + b^2 since bc seems long I am using that as the hypotenuse.
9^2 = 6^2 + b^2
81 = 36 + b^2
81-36 = b^2
45 = b^2
6.7 = b
so AC = 6.7
Hank has 4 green marbles for every 9 red marbles. If hank has 39 total marbles, how many green marbles does he have? pls answer ASAP it for assignment
Answer:
12 green marbles
Step-by-step explanation:
in this case we have to add the the green marbles as 4 and red marbles as 9
so, 4 + 9 = 13 and divide the total marbles to it
so, 39/13 = 3
so, here we have 3 times marble in 13 green marble to get the total number
so, 3 (13)
so, in this case we have to separate the green and red
so, 13 as ( 9 red + 4 green)
so,3 times ( 9 red + 4 green)
in this case we can use distributive property of multiplication
so, 3 times 9 red = 27 is the total red marbles
and 3 times 4 green = 12 is the total green marbles
to check the answer we have to add this two
so, 27 red marbles + 12 green marbles = 39 total marbles
so, that's why it is 12 green marbles

21. Which two ratios can be represented by a ratio of 7 to 12?
A the ratio of shells to rocks if there are 7 rocks and 12 shells
B the ratio of shoes to dresses if there are 7 dresses and 12 shoes
c the ratio of shots made to shots taken if 7 out of 12 shots taken are made
D the ratio of sick patients to total patients if there are 7 sick patients and 12 healthy patients
E the ratio of small dogs to big dogs if there are 7 small dogs and 12 big dogs
Page 9
Go to the next page
Answer:
c the ratio of shots made to shots taken if 7 out of 12 shots taken are made
E the ratio of small dogs to big dogs if there are 7 small dogs and 12 big dogs
Step-by-step explanation:
Ratio of a to b:
The ratio of a to b is given by a divided by b.
A the ratio of shells to rocks if there are 7 rocks and 12 shells
12 shells and 7 rocks, so this ratio is 12 to 7.
B the ratio of shoes to dresses if there are 7 dresses and 12 shoes
12 shoes and 7 dresses, so this ratio is 12 to 7.
c the ratio of shots made to shots taken if 7 out of 12 shots taken are made
7 shots made out of 12 taken, so this ratio is 7 to 12, and c is one of the correct options.
D the ratio of sick patients to total patients if there are 7 sick patients and 12 healthy patients
7 sick patients
7 + 12 = 19 total patients
So this ratio is 7 to 19
E the ratio of small dogs to big dogs if there are 7 small dogs and 12 big dogs
7 small dogs and 12 big dogs, so this ratio is 7 to 12, and e is the other correct option.

One fruit punch has 10% juice and another has 50%. How much of the 10% should be mixed with 30 gal of the 50% to create punch that is 25% juice
Answer:
We combine x ounces of 100% juice
with 40-x of 10% juice
to get 40 ounces of 55% juice
x + 0.1(40-x) = .55(40)
x + 4 - 0.1x = 22
0.9x + 4 = 22
.09x = 18
x = 20 ounces of 100% juice
40-x = 20 ounces of 10% juice
We combine 20 ounces of each.

A company's human resources department was interested in the average number of years that a person works before retiring. The sample of size 11 follows: Based on the values of the arithmetic mean, median, and mode, what is the most likely shape of the distribution
Answer:
hello your question is incomplete below is the complete question
A company's human resources department was interested in the average number of years that a person works before retiring. The sample of size 11 follows: 12 16 18 19,21 21, 21,22 24 24 26What is the arithmetic mean, median and mode? what is the most likely shape of the distribution
answer :
i) mean = 20.36
ii) median = 21
iii) mode = 21
iv) The most likely shape is a Bell - shaped curve
Step-by-step explanation:
sample size = 11
values ( observations ) = 12, 16, 18, 19,21,21,21,22,24,24,26
i) mean
= ∑ values / sample size = 224 / 11 = 20.36
ii) median
median is the value of the data located at the center of the string of data
to determine the middle position = ( n+1 / 2 )
where n = sample size
hence position of median value = 11 + 1 / 2 = 12 / 2 = 6
the value at the 6th position = 21 ( median )
iii) mode
mode = most repeated value in the series of data
hence mode value = 21

Step-by-step explanation:
Airplane One 425m/h x 2h= 850 miles traveled N5°W
Airplane Two 530m/h x 2h= 1060 miles traveled N67°E
5 degrees + 67 degrees = 72 degrees divergence of the Airplane One and Two
Draw a triangle, the smallest side is 850 and adjacent to 1060 side. The angle between these two sides is 72 degrees
Use the acronym SOH CAH TOA to find the side which is the distance between the 2 airplanes after 2 hours
sine 72= opposite/hypotheneus
sine 72= opposite/1060
opposite = (sine 72)(1060)= 1008 miles distance between Airplane One and Airplane Two
