If $12000 is invested in an account in which the interest earned is continuously compounded at a rate of 2.5% for 3 years
Answer:
$ 12,934.61
Step-by-step explanation:
The formula for Compound Interest Compounded continuously is given as:
A = Pe^rt
A = Amount after t years
r = Interest rate = 2.5%
t = Time after t years = 3
P = Principal = Initial amount invested = $12,000
First, convert R percent to r a decimal
r = R/100
r = 2.5%/100
r = 0.025 per year,
Then, solve our equation for A
A = Pe^rt
A = 12,000 × e^(0.025 × 3)
A = $ 12,934.61
The total amount from compound interest on an original principal of $12,000.00 at a rate of 2.5% per year compounded continuously over 3 years is $ 12,934.61.

Teacher chooses to students in a class of 15 girls and 10 boys the students are randomly choosing what is the probability that the teacher chooses to girls
Answer:
7/20
Step-by-step explanation:
So first we know that there are a total od 25 students
15+10=25
And the probability of choosing the first girl is 15/25 or 3/5 simpler terms.
Now to be able to choose another girl in a row just multiply the then probability
So we started off with 25, if a girl was choosen, the population would b 24
and with 24, there is a missing girl so instead of 15 it is 14
now 14/24 or 7/12 simplified
multiply the two
7/12*3/5=21/60
Simplified
7/20

A large bowl holds 5 2/3 cups of punch. Some more punch is added to the bowl to make a total of 10 cups of punch. Let represent the number of cups of punch that are added to the bowl. Write and solve an equation to find the number of cups of punch that are added to the bowl.
Answer:
4 1/3 cups
Step-by-step explanation:
All you have to do for this one is subtract 5 2/3 from 10, which is 4 1/3. Your equation could be 10-5 2/3=x.

Answer:
f(x)= -2|x-3|-1
(Hi Jasmine! I just wanted to help you with this question but I might be wrong)
Step-by-step explanation:
f(x) = a|x-h|+k
f(x)= a|x-3|-1
-7 = a |0-3| -1
-7 = a |-3| -1 <-- add to -7
-6 = a |-3|
-6 = 3a
-6/3 = a
-2 = a
---------------------------------- -------------------------------------------------
The equation of the absolute value is f(x)= -2|x-3|-1

What is the area of the triangle in the diagram?
Answer:
A is the correct answer
Step-by-step explanation:
We need to figure out the base and the height. We can do that using pythagorean's theorem.
The others either misused the pythagorean theorem or got the 1/2*base*height formula wrong, so A is the answer.

Simplify this expression: -2x + 3 – (5 – 6x). Can someone pls explain how to do this dont just give the awnser
Answer:
-2x + 3 – (5 – 6x) = 4x - 2
Step-by-step explanation:
The given expression is :
-2x + 3 – (5 – 6x)
We need to simplify the above expression. First opening the brackets.
-2x + 3 – (5 – 6x) = -2x + 3 – 5 + 6x
Taking like terms together,
= -2x+6x + 3 -5
= 4x - 2
So, the simplified expression is 4x - 2.

Answer:
The simplified expression of [tex]\frac{7^{4}.7^{6}}{7^{8}}[/tex] is 7² ⇒ C
Step-by-step explanation:
Let us revise some rules of exponent
[tex]a^{m}[/tex] × [tex]a^{n}[/tex] = [tex]a^{m+n}[/tex][tex]\frac{a^{m}}{a^{n}}[/tex] = [tex]a^{m-n}[/tex]Let us solve the question
∵ The expression is [tex]\frac{7^{4}.7^{6}}{7^{8}}[/tex]
→ By using the first rule above add the exponents of 7
∴ [tex]\frac{7^{4}.7^{6}}{7^{8}}[/tex] = [tex]\frac{7^{4+6}}{7^{8}}[/tex]
∴ [tex]\frac{7^{4}.7^{6}}{7^{8}}[/tex] = [tex]\frac{7^{10}}{7^{8}}[/tex]
→ By using the second rule above, subtract the exponents of 7
∵ [tex]\frac{7^{4}.7^{6}}{7^{8}}[/tex] = [tex]7^{10-8}[/tex]
∴ [tex]\frac{7^{4}.7^{6}}{7^{8}}[/tex] = 7²
∴ The simplified expression of [tex]\frac{7^{4}.7^{6}}{7^{8}}[/tex] is 7²

Rachel participated in a 12-kilometer walkathon to raise money for her favorite charity. If it took her 2.5 hours to complete it, what was the rate in kilometers per hour?
Step-by-step explanation:
here they gave 12 km are reached by 2.5 hours so we. should how much time they took for 1km
12/ 2.5 which is also 150min
12km which is also 12000
12000/150= 80m
it took 80m in 1min so
1hr = 60min
1hr x 80m
60x80
4800
convert it intlo km
4800/1000
4.8km
so it took 4.8 km for 1hour
The time to complete the race is 2.5 hours, then the rate will be equal to 4.8 kilometers per hour.
What are arithmetic operations?The four basic operations of arithmetic can be used to add, subtract, multiply, or divide two or even more quantities.
They cover topics like the study of integers and the order of operations, which are relevant to all other areas of mathematics including algebra, data processing, and geometry.
As per the given information in the question,
Total distance = 12 kilometers
Total time taken to complete 12 kilometers = 2.5 hours
Then, the rate in kilometers per hour will be,
= 12/2.5
= 4.8 kilometers per hour.
