A teenager puts $50 into an investment account in January. If by December the balance in the account increases by 17%, what is the amount of money in the account in December?.
Answers
Answer:
58.50
Step-by-step explanation:
Multiply 50 and .17 which equals 8.5 then add that to 50.
The amount of money in the account in December with a rate of 17% of the initial amount of $50 is $58.5.
What is the percentage?The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.
A teenager puts $50 into an investment account in January.
Let, he deposited on first January.
If by December the balance in the account increases by 17%,
Let the amount by the 31 first of December will be
Then the amount will be given as
\(A = P (1 + \dfrac{r}{100})^t\)
P = $50
r = 17%
t = 1
Then we have
\(\rm A = 50(1 + \dfrac{17}{100})^1\\\\A = 50(1 + 0.17)\\\\A = 50 * 1.17 \\\\A = 58.5\)

On a string of lights there are 200 bulbs. After many years of use, 19 of them have burned out. Approximately what percentage of bulbs have burned out?
Answers
Answer:
8.5% (you can approximate that, that's the exact number and it isn't too funky)
Step-by-step explanation:
Percentage is out of 100, and over here we see that 200 is 2 times the amount of 100. So that means that if we divide 200 by 2, we get 100, which means we also divide 19/2 to get 8.5. That means, out of 100 light bulbs, 8.5 of them burned out. This is really easy to convert because the percentage is already out of 100, so you just make 8.5 into a percent which is 8.5%

suppose that the radius is expanding at a rate of 0.6 inches per second. how fast is the volume changing when the radius is 2.3 inches? use at least 5 decimal places in your answer.
Answers
Using the theories of Application of derivative,we got that 59.11221inches³/sec is rate of volume changing when the radius is 2.3 inches.
We are given rate of change of radius (dr/dt)=0.6inches
We know very well that volume of sphere is given by (4/3)πr³
where r is the radius of the sphere.
Now, differentiating the volume with respect to radius, we get
=>dV/dr=4πr²
=>dV/dt=(dv/dr)·(dr/dt)
=>dV/dt=4πr².(dr/dt)
We are given that dr/dt=0.6inches/sec
So, dV/dt=4πr²·(0.6)
Now, putting values of r=2.3
dV/dt=4π(2.3)²×(0.6)
=>dV/dt=4×3.14×2.3×2.3×0.6
=>dV/dt=59.11221inches³/sec
Hence, if we suppose suppose that the radius is expanding at a rate of 0.6 inches per second, the volume is changing at the rate of 59.11221inches³/sec when the radius is 2.3 inches.

B. 150 degrees,
The interior angles are 150 degrees.
The exterior angles are 30 degrees,
Hence 30•12=360, 150•12=1800.
C. No, not without the use of other regular polygons to fill the gaps in between. So, you can use it to tile a flat surface, but there will be gaps and voids to fill with other tile. Or if you want to get technical, for you tile the plane by congruent regular polygons, there must be polygons meeting at each vertex. Thus the interior angles of each polygon must be 2/, for some positive integer . The vertices always come together at some point. That is, with rectangular tiles there are always groups of 4 tiles, and the 4 corners are 90 degrees each so 4 of them add up to 360. A hexagon has an interior angle measure of 120, and 120 is the greatest factor of 360 (other than 180, which is a straight line, or 360). If you have polygons with 7 or more sides, their corners will not fit nicely to add up to 360 degrees:)

(-5, -4) and (-13,2)
Answers
The slope of the line passing through the points (-5, -4) and (-13, 2) is -3/4.
What is the slope of the line through the given points?Slope is simply expressed as a change in y over the change in x.
It is expressed as
\(m = \frac{y_2 - y_1}{x_2 - x_1}\)
Given the points:
(-5, -4) and (-13,2)
Point (-5, -4):
x₁ = -5
y₁ = -4
Point (-13,2):
x₂ = -13
y₂ = 2
Plug the given x and y values into the slope formula and simplify.
\(m = \frac{y_2 - y_1}{x_2 - x_1}\\\\m = \frac{2 - (-4)}{-13 - (-5)}\\\\m = \frac{2 + 4}{-13 + 5}\\\\m = \frac{6}{-8}\\\\m = -\frac{3}{4}\)

Jessica reads a story about a turtle that swam 16 feet in 24 seconds. She assumes that the time t that it takes the turtle to swim a distance of d feet is a proportional relationship.Jessica starts to create the table shown for other times and distances the turtle swims.
Answers
Equation to represent this proportional relationship is d = tk, where t is time, d is distance and k is the constant of proportionality.
Therefore, given d = 16 and t = 24, we substitue in the above equation and find k:
\(\begin{gathered} d=tk \\ 16=24k \\ \frac{16}{24}=\frac{24k}{24} \\ k=\frac{2}{3} \end{gathered}\)Next let's complete the table by substituting the value of k and the other given value of t or d, as the case may be:
Time = 1 sec
\(\begin{gathered} d=tk \\ d=1\cdot\frac{2}{3} \\ d=\frac{2}{3} \end{gathered}\)Distance = 10 feet
\(\begin{gathered} 10=t\cdot\frac{2}{3} \\ 10\cdot\frac{3}{2}=t\cdot\frac{2}{3}\cdot\frac{3}{2} \\ \frac{30}{2}=t\cdot1 \\ t=15 \end{gathered}\)Time = 45 sec
\(\begin{gathered} d=45\cdot\frac{2}{3} \\ d=\frac{90}{3} \\ d=30 \end{gathered}\)Answer:

use an identity to reduce the power of the trigonometric function to a trigonometric function raised to the first power. sin2(x) =
Answers
We can use the identity sin²(x) = 1/2 - 1/2 cos(2x) to reduce the power of the trigonometric function to a trigonometric function raised to the first power.
The identity sin²(x) = 1/2 - 1/2 cos(2x) can be derived using the double angle formula for cosine. The double angle formula for cosine states that cos(2x) = cos²(x) - sin²(x).
Rearranging this formula, we get sin²(x) = cos²(x) - cos²(x) + sin²(x).
Simplifying, we get sin²(x) = 1 - cos²(x).
Dividing both sides by 2, we get sin²(x) = 1/2 - 1/2 cos²(x).
Substituting cos²(x) with cos(2x)/2, we get sin²(x) = 1/2 - 1/2 cos(2x).
Therefore, sin²(x) can be expressed as a trigonometric function raised to the first power, 1/2 - 1/2 cos(2x).

11) Which measurement(s) would help determine absolute dates by radiometric means?
A) the accumulation of the daughter isotope
B) the loss of parent isotopes
C) the loss of daughter isotopes
D) Three of the responses above are correct.
E) Two of the responses above are correct.
Answers
The correct answer is E) Two of the responses above are correct:
The measurement(s) that would help determine absolute dates by radiometric means are the accumulation of the daughter isotope and the loss of parent isotopes. These two measurements are crucial in radiometric dating methods, which rely on the decay of radioactive isotopes in rocks and minerals over time.
In radiometric dating, scientists measure the ratio of parent isotopes to daughter isotopes in a sample. The parent isotopes decay at a known rate, converting into daughter isotopes. By determining the amount of parent isotope that has decayed and the accumulation of daughter isotope, scientists can calculate the age of the sample.
For example, if a rock sample contains a radioactive isotope with a half-life of 1 million years, and 75% of the parent isotope has decayed into the daughter isotope, it can be inferred that the rock is approximately 2 million years old (since two half-lives have passed).
Therefore, the correct answer is E) Two of the responses above are correct: the accumulation of the daughter isotope and the loss of parent isotopes are measurements that help determine absolute dates by radiometric means.

Step-by-step explanation:
The odds that Romance will win are listed as 2 : 3
We can rewrite this as:
The probability that Romance will win \(=\dfrac23\)
The odds that Downhill will win are 1 : 2.
The probability that Downhill will win \(=\dfrac12\)
Therefore:
The probability that either Romance or Downhill wins
=P(Romance Wins)+P(Downhill wins)
\(=\dfrac23+\dfrac12\\=\dfrac{2(2)+3(1)}{6}\\=\dfrac76\)

A triangle is a three-sided polygon that consists of three sides and three angles. An extension of a side of a triangle is a line segment that is drawn from one of the endpoints of the side that extends beyond the side.
If we extend one side of the triangle and draw a line that passes through one of the adjacent vertices, the resulting shape is called a triangle's exterior angle. This exterior angle is formed by one side of the triangle and the extension of an adjacent side.
