If Jonathan has 2 times as many dimes as quarters and they have a combined value of 360 cents, how many of each coin does he have?
Answer:
16 dimes8 quartersStep-by-step explanation:
When ratios of quantities are given, it is often convenient to consider a group of objects in which the objects have that ratio.
How many groups?Here, we have 2 dimes for each quarter, so a group of 2 dimes and 1 quarter is a useful group for this problem. Its value is 2×$0.10 +0.25 = $0.45.
The total value of all of the groups is $3.60, so there must be ...
$3.60/($0.45/group) = 8 groups
The 8 groups of coins will have 16 dimes and 8 quarters.

The height of the tower based on the angle of elevation given is
How to calculate the height?From the information given, the tower is 45m, the clinometer is set at 1.3m above the ground, and the angle of elevation is 32°.
This can be illustrated as:
tan 32° = (45 - 1.3)/x
tan 32° = 43.7/x
x = 43.7/tan 32°
x = 69.93m.
Also, for triangle ACD,
tan 47° = (43.7 + y)/x
x × tan 47° = 43.7 + y
74.49 = 43.7 + y
y = 31.29
The height of the tower will be:
= 43.7 + 31.29

Assuming you are a business owner with different shareholders. How may zero growth stock valuation and constant stock valuation affect your business operations?
The ways that zero growth stock valuation can affect business operations is that:
When zero-growth model states that the dividend is at the same rate, it shows that one has no measure of growth in terms of dividends. This therefore shows that stock price is equal to the annual dividends and divided also by the needed rate of return.What ways does constant stock valuation affect business operations?The Constant stock valuation is known to be a kind of share evaluation as it states that the dividends paid by a firm will consistently increase at a constant growth rate.
This will help one to know especially investors on how to set or know the fair price that one needs to pay for a stock on daily basis today by due to future dividend payments.
The overall statement is that stock value affect one's business operations as the company's stock price is one that shows an investor perception of their capability to get profit and also if they can grow their profits in terms of future times.

The graph of f(x)=x2 is shown. Use the parabola tool to graph the function g(x)=(15x)2 . To graph a parabola, first plot the vertex then plot another point on the parabola
The graph of the parabola can be seen in the image below.
How to plot the parabola?Here we have the function:
g(x) = (15x)^2
Notice that this is a contraction of scale factor 15 of the function f(x) = x^2
To graph this, we can just evaluate the function in 3 points, the vertex and two other ones.
for x = 0.
g(0) = (15*0)^2 = 0
So we have the point (0, 0).
Evaluating in x = 1 and x = -1 (give the same value) we get:
g(±1) = (±15)^2 = 225
So we have the points (1, 225) and (-1, 225).

Which of the following inequalities will help her determine values of h, the number of hours that Jasmine can work so she can afford the new headphones?
The number of hours that Jasmine can work so she can afford the new headphones x = 6 weeks.
let x represent the number of weeks it will take to save enough money.
If she saves $11 each week, then in x weeks she will save 11x dollars.
Add this to the 107 she has already saved, and at the end of 11 weeks she will have
11x + 107 dollars.
We want the amount saved to be equal to the price of the bike, so our equation is
11x + 107 = 173
In a word problem, writing the equation is usually the hardest part. Now we solve the equation.

The value of the house in the year 2010 is 150056.47.
What is growth rate?The growth rate of a value (GDP, turnover, wages, etc.) measures its change from one period to another (month, quarter, year)
Value
v(t) = V0 ( 1 + r)^t
let V0 = 106, v(20) = 146
So,
146 = 110(1 + r )^20
146/110 = (1 + r )^20
1.327 = (1 + r )^20
1+ r = 1.014
r= 0.014
So, annual growth rate is 1.4%.

Calculate exponents
[tex]\frac{4y}{1.103812890625}+y-2y(1.1025)=1500\\[/tex]
Simplify:
[tex]3.6238025791990193084270042653997y + y - 2.205y = 1500[/tex]
Add like terms
[tex]2.4188025791990193084270042653997y \approx 1500[/tex]
Divide both sides by 7.012
[tex]y\approx 213.91[/tex][tex]y\approx620.14[/tex]
Answer:
y = $620.14 (nearest cent)
Step-by-step explanation:
Given equation:
[tex]\dfrac{4y}{1.025^4}+y-2y(1.05)^2=\$1,500[/tex]
Factor out y from the left side:
[tex]\implies y\left(\dfrac{4}{1.025^4}+1-2(1.05)^2\right)=\$1,500[/tex]
Carry out the arithmetic operations inside the parentheses by following the order of operations PEMDAS:
Calculate the exponents:
[tex]\implies y\left(\dfrac{4}{1.103812891...}+1-2(1.1025)\right)=\$1,500[/tex]
Carry out the multiplication and division from left to right:
[tex]\implies y\left(3.623802579...+1-2.205\right)=\$1,500[/tex]
Carry out the addition and subtraction from left to right:
[tex]\implies y\left(4.623802579...-2.205\right)=\$1,500[/tex]
[tex]\implies y\left(2.418802579...\right)=\$1,500[/tex]
Finally, divide both sides by the coefficient of y to isolate y:
[tex]\implies \dfrac{y\left(2.418802579...\right)}{2.418802579...}=\dfrac{\$1,500}{2.418802579...}[/tex]

The price p based on the equation given is p = 3000 - 0.1x.
How to express the price?The equation given in the question is x = 3000 - 10p. The price(p) will be:
x = 3000 - 10p.
Make p the subject of the formula
x + 10p = 3000
10p = 3000 - x
p = (3000 - x)/10
p = 3000 - 0.1x
The revenue will be price multiplied by quantity. This will be:

What is the probability that a random sample of 10 second grade students from the city results in a mean reading rate of more than 96 words per minute
Using the normal distribution, it is found that there is a 0.1029 = 10.29% probability that the sample mean is above 96.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].Researching the problem on the internet, the parameters are given as follows:
[tex]\mu = 92, \sigma = 10, n = 10, s = \frac{10}{\sqrt{10}} = 3.1623[/tex]
The probability that the sample mean is above 96 is one subtracted by the p-value of Z when X = 96, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem:
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{96 - 92}{3.1623}[/tex]
Z = 1.265
Z = 1.265 has a p-value of 0.8971.
