You deposit $10,000 in an account earning 8% interest, compounded semi-monthly (twice a month). You plan to leave the account untouched for 25 years. How much interest will you earn over the 25 years?
Answer:
Po=10,000
10,000((1+.05/24)^600=34858.07, but $10000 must be subtracted because it was principal.
Interest is $24,858.07

Find the measure of the largest angle in the triangle
shown.
15x
24x
21x
Answer:
72°
Step-by-step explanation:
Find the image of the question attached
The sum of angle in a triangle is 180°
Hence:
15x+24x+21x = 180°
60x =180
x =180/60
x= 3
Get the largest angle
The largest angle out of the angles is 24x
24x =24(3)
24(3) =72°
Hence the measure of the largest angle is 72°
Martina has a circle with a diameter
of 6 inches. She doubled the
diameter to make a new circle.
Now, Martina says that the ratio of
the circle's circumference to its
diameter has also doubled. Correct
her mistake.
Answer:
The ratio of the circumference to its diameter remains the same.
Step-by-step explanation:
Given,
diameter of circle = 6 inch
diameter is doubled.
New diameter of circle = 2 x 6 = 12 inch
We know that,
The Circumference of a circle is 2 π r or π d where r is the radius of the circle and d is the diameter of the circle.
Circumference of the circle when the diameter is 6 inches.
C₁ = 6π
Ratio of circumference to diameter
Ratio = [tex]\dfrac{6\pi}{6}[/tex]
Ratio = π
When the diameter is 12 inches
C₂ = 12 π
Ratio of circumference to diameter
Ratio = [tex]\dfrac{12\pi}{12}[/tex]
Ratio = π
Now, the correct statement is the ratio of the circumference to its diameter remains the same if the diameter is doubled.

131 is the weight of the lightest person in the group.
If we look closely the stem has the 13 as the lowest number. And corresponding to it the least number is 1.
Therefore the lightest weight person is 131 .All other weights are greater than 131 e.g 132 , 134 and 136 .
The data shows there are 131 ,131, 132,132,134,134, and 136 weights in the least weight group. So out of these 131 is the smallest.

Question 5 (5 points)
(04.05 MC)
Which graph best represents the function f(x) = 4(1.5)x? (5 points)
Question 5 options:
1)
graph of increasing exponential function going through point 0, 2
2)
graph of increasing exponential function going through point 0, 3
3)
graph of increasing exponential function going through point 0, 1
4)
graph of increasing exponential function going through point 0, 4
Answer:
I am guessing the equation you meant to type is [tex]f(x)=4(1.5)^x[/tex]. Based on this information, I know that the answer is:
4) Graph of increasing exponential function going through point (0, 4).
Step-by-step explanation:
I graphed the function in Desmos, and I found that the y-intercept is (0,4). Answer choices 1-3 all have varying y-intercept options, while option number 4 says the graph is going through point (0,4) so we know that's the right answer.
I hope this helps! Feel free to give me Brainliest if you feel this helped. Have a good day, and good luck with the rest of your assignment. I'll attach a photo of the graph below, so you understand the graph.
Answer:
I had the same exact problem on my quiz! The answer is D, because the y intercept is (0,4). Graphing the equation really helped me understand it! :)

He shuffles the deck and selects one card and then another. In its simplest form, what is the probability that he draws a pair of tens?
Answer:
Step-by-step explanation:
Probability of getting pair of 10's: 1/221
We have the following information available from the question is:
There are four suits with 13 cards in each from ace through to king.
Two cards one after another are drawn from a deck of 52 cards.
We have to find the probability that he draws a pair of tens.
Now, According to the question:
We know that:
In a pack of 52 cards, there is 4 tens:
Then, Probability of getting 10 in first attempt:
= 4/52
After drawn first ten, There is 51 cards are remaining in a pack of cards and no. of ten's = 3
Probability of getting 10 in 2nd attempt :
= 3/51
Probability of getting pair of 10's:
[tex]=\frac{4}{52} (\frac{3}{51} )=\frac{12}{2652}[/tex]
