An account is opened with an initial deposit of $1100 and earns 3.7% interest compounded monthly.
What will the account be worth in 15 years?
Round your answer to the nearest cent.
In 15 years, the account will be worth $1896 if the 3.7% interest is compounded monthly on initial deposit of $1100.
What is compound interest?It is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on principal plus interest.
Given Data
A = [tex]P(1+\frac{r}{100} )^{t}[/tex]
P=$1100
r =3.7%
t = 15years
Substitute the values in formula, A = [tex]P(1+\frac{r}{100} )^{t}[/tex]
A= 1100(1+{3.7/100})¹⁵
A = 1100(1+0.037)¹⁵
A = 1100(1.037)¹⁵
A= 1100(1.724)
A= 1896.4
Round off to nearest cent - $1896
Hence, $1896 will the account be worth in 15 years

Which rational number equals 0.5?
A. 1/50
B. 1/5
C. 5/10
D. 5/9
Answer:
C. 5/10
Step-by-step explanation:
Using a calculator:
Divide each numerator by each denominator. The answer must be 0.5
A. 1/50 = 0.02
B. 1/5 = 0.2
C. 5/10 = 0.5
D. 5/9 = 0.555...
Answer: C. 5/10
Without a calculator.
0.5 as a fraction is 1/2. Notice the denominator, 2, is twice the numerator, 1.
The answer also must have a denominator that is twice the numerator.
A. 1/50 2 × 1 = 2, not 50
B. 1/5 2 × 1 = 2, not 5
C. 5/10 2 × 5 = 10; this is it.
D. 5/9 2 × 5 = 10, not 9
Answer: C. 5/10
1 a) A restaurant is open 24 hours a day. The manager wants to divide the day into work shifts of equal length. The shifts w=should not overlap. All shifts durations should be a whole number of hours. Describe the different ways this can be done.
b) The manager turns on the restaurant's two neon signs at the same time. Both signs blink as they are turned o. One blinks every 9 seconds. The other sign blinks every 15 seconds. In how many seconds will they blink together again?
The possible answers for the restaurants are Three 8-hour shifts; four 6-hour shifts; six 4-hour shifts.
2. The seconds that they will blink together again is 45 seconds.
How to illustrate the information?Here we have to determine the factors of 24 for the shifts i.e. 1, 2, 3, 4, 6, 8, 12, 24 .
A 1-hour shift does not make much sense; most employers will also not use a 2-hour or 3-hour shift.
Restaurants typically do not use 12-hour shifts either, and employers do not use 24-hour shifts either.
Since both signs blink as they are turned on and one blinks every 9 seconds. The other sign blinks every 15 seconds. The least common multiple is 45.

Answer:
4.
∠ABC + ∠BCA + ∠CAB = 180
therefore, ∠ABC = 180 - ∠BCA - ∠CAB
using this formula to solve 4a, 4b and 4c:
4a. ∠ABC = 180 - ∠BCA - ∠CAB = 180 - 49 -57 = 26
∠ABC = 26
4b. ∠ABC = 180 - ∠BCA - ∠CAB = 180 - 28 -90 = 62
∠ABC = 62
4c. ∠ABC = 180 - ∠BCA - ∠CAB = 180 - 38 - 25 = 117
∠ABC = 117
5a. In the Triangle ABC, ∠BCA + ∠CAB + ∠ABC = 180
∠BCA = 180 - ∠CAB - ∠ABC = 180 - 55 - 60 = 65
∠BCA = 65
∠BCD + ∠BCA = 180
therefore substituting for ∠BCA in, ∠BCD = 180 - ∠BCA = 180 - 65 = 115
∠BCD =115
5b. In the Triangle ABC, ∠BCA + ∠CAB + ∠ABC = 180
∠BCA = 180 - ∠CAB - ∠ABC = 180 - 125 - 30 = 25
∠BCA = 25
∠BCD + ∠BCA = 180
therefore substituting for ∠BCA in, ∠BCD = 180 - ∠BCA = 180 - 25 = 155
∠BCD = 155
5c. ∠ABD + ∠CBD = 180
therefore ∠CBD = 180 - ∠ABD = 180 - 132 = 48
∠CBD = 48
In the Triangle BCD, ∠CBD + ∠BDC + ∠BCD = 180
therefore ∠BCD = 180 - ∠CBD - ∠BDC = 180 - 48 - 71 = 61
∠BCD =61
6. 4 angles of a quadrilateral = 360
∠a+110+60+80=360
∠a=360-110-60-80=110
∠a = 110
7. four angles of a quadrilateral = 360
using his formula to solve for ∠a, ∠b and ∠c.
for angle a: ∠a+110+95+63=360
∠a=360-110-95-63=92
∠a = 92
for angle b: ∠b+40+62+35=360
∠b=360-40-62-35=223
∠b=223
for angle c: ∠c+100+172+35=360
∠c=360-100-172-35=53

Jaspar deposits £2,500 into a savings account at 7% per annum compound interest.
How much does he have in his account after 2 years?
Jasper had 362.25 in his account after two years, per the given statement.
What exactly is compound interest?The interest you earn upon interest is known as compound interest. This may be demonstrated with simple math: if you have $100 and that it earns 5% interest every year, you will have $105 at the end of the first year. You'll have $110.25 by the end of the second year.
According to the given data:Given:
Jaspar deposits £2,500
interest rate = 7
Time = 2 year
Compound interest is interest calculated on the aggregate amount rather than the principle amount alone.
Amount = P(1+r/100)^n
=2500(1+7/100)²
=2500(100+7/100)²
= 2500(107/100)²
= 2862.25

The equation for the line parallel to the graph of y = 6x + -2 with the same y- intercept as the graph of y = 36x + 2 is written as y = mx + b. Determine the values of m and b. What is the value of m + b?
The values of m and b are 6 and 2 respectively and the value of m + b is 8.
The slope intercept of the straight line is used to find the equation of the straight line. The slope intercept formula requires knowing the slope of the line and the point of intersection of the line with the y-axis. Consider a line with slope "m" and y-intercept "b".

The number in standard notation is 143,000.
The number in scientific notation is 4.39 x 10^-4
What is scientific and standard notation?
Scientific notation is used to compress large numbers into smaller numbers. In order to write a number in scientific notation, the number is written as a decimal number, between 1 and 10 and multiplied by a power of 10.
For example:
• The number : 1 x 10² is equivalent to 100
• The number 5 x 10³ is equivalent to 500
When changing a number that is less than 1 to scientific notation, there would be a negative sign before the power.
0.000439 = 4.39 x 10^-4
In order to convert a number from scientific notation to standard notation, multiply the number by its power.
