You buy a house for $299,00. If you make a 20% down payment, how much would you pay in total per month for the 30 year loan if you pay $3200/year in taxes, $1050/year in insurance and $28/month forthe home owners association?
Answers
Charlene calculated that the monthly patyment, including interests is $ 692.88.
Taxes = $ 3,200 annually, if we divide it by 12, we will find the monthly amount, this way:
3,200/12 = $ 266.67
Insurance = $ 1,050 annually, if we divide it by 12, we will find the monthly amount, this way:
1,,050/12 = $ 87.50
Home owners association = $ 28
Therefore, the monthly payment would be:
692.88 + 266.67 + 87.50 + 28

Answers
Answer: 12.66%
First, we will solve the probability that 3 adults, 2 adults, 1 adult and no adult use their smartphones in meetings or classes,
To solve for this, we will use the following equation
[tex]11Cn\times0.49^n\times0.51^{11-n}[/tex]*Probability of adults using their phones for meetings or classes are 0.49.
1 - 0.49 = 0.51
*Probability of adults NOT using their phones are 0.51
Now, with the values of n at:
n = 0
n = 1
n = 2
n = 3
[tex]11Cn\times0.49^n\times0.51^{11-n}=11C0\times0.49^0\times0.51^{11-0}=0.0006[/tex][tex]11Cn\times0.49^n\times0.51^{11-n}=11C1\times0.49^1\times0.51^{11-1}=0.0064[/tex][tex]11Cn\times0.49^n\times0.51^{11-n}=11C2\times0.49^2\times0.51^{11-2}=0.0308[/tex][tex]11Cn\times0.49^n\times0.51^{11-n}=11C3\times0.49^3\times0.51^{11-3}=0.0888[/tex]Now, we will add these altogether to get the probability that fewer than 4 of them use their smartphones in meetings or classes.
[tex]0.0006+0.0064+0.0308+0.0888=0.1266=12.66\%[/tex]The answer would be 12.66%.

we have
[tex]\begin{gathered} height\text{ of the cylinder = 4 cm} \\ diameter\text{ of the circular end = 2 cm} \end{gathered}[/tex]but

Answers
A volume of a cube is given by V=L^3 where L is its side length. If a cube is dilated by a factor of 3.5, it means that its sidelength is increased by a factor of 3.5, i.e. if S is the first length, the new length L satisfies L=3.5*S. Now, the old cube's volume v was v=S^3, after it has expanded to the new sidelength L its new volume V is V=L^3. Using the equation L=3.5*S we can replace L in the equation for V like follows:
V=(3.5*S)^3
Expanding the product we get
V=[(3.5)^3]*(S^3)=42.875*(S^3)
We previously noticed that the prior volume of the cube was v=S^3. Replacing v for S^3 in the previeus equation gives us:
V=42.875v
Thus, the factor by wich the volume of the original cube was scaled up is 42.875

From the question we can deduce that, the squares shaded in red represent the area tomatoes are planted in the garden.
The squares unshaded represents the area corn is planted in the garden.
Observe carefully that the total squares shaded in red are 24 (that is 4 by 6 OR 4 times 6). The unshaded squares total 18 (that is 3 times 6).
Each unit (or each square) is 1 square foot. This means on Nora's garden, she has tomatoes planted on 24 square feet. Also she has corn planted on 18 square feet.
Therefore, the difference between both areas is
Difference = 24 - 18

You have $10,000 in a savings account. You want to take most of the money out and invest it in stocks and bonds. You decide to invest nine times as much as you leave in the account. You also decide to invest five times as much in stocks as in bonds. How much will you invest in stocks, how much in bonds, and how much will youleave in savings?
Answers
Answer:
7,500 in stocks
1,500 in bonds
1,000 in savings
Explanation:
First, let's call x the quantity that you will leave in saving and y the quantity that you will invest in stocks and z the quantity that you will invest in bonds.
Now, we can formulate the following equations:
x + y + z = 10,000
y + z = 9x
y = 5z
Because you have 10,000 in savings, you decide to invest nine times as much as you leave in the account, and you also decide to invest five times as much in stocks as in bonds.
So, we can rewrite the expressions as:
x + y + z = 10,000
-9x + y + z = 0
y - 5z = 0
Now, we can multiply the second equation by -1 and sum this equation with the first one as:
-9x + y + z = 0
(-9x + y + z)*(-1) = 0*(-1)
9x - y - z = 0
Then, the sum is equal to:
x + y + z = 10,000
9x - y - z = 0
10x - 0 - 0 = 10,000
10x = 10,000
x = 10,000/10
x = 1,000
Replacing x on the second equation, we get:
9x - y - z = 0
9*1,000 - y - z = 0
9,000 - y - z = 0
-y - z = - 9,000
Now, we can add the equation with the third one as:
-y - z = - 9,000
y - 5z = 0
0 - 6z = -9,000
-6z = -9000
z = -9000/(-6)
z = 1,500
Finally, using the third equation, the value of y is equal to:
y = 5z
y = 5*1500
y = 7,500
Therefore, you will invest 7,500 in stocks, 1,500 in bonds and you will leave 1,000 in savings.

19. If the cost price of 18 apples is the same as selling price of 16 apples, what is the profit in $ as well as percentage gain?
Answers
Answer
Percent Gain = 12.5%
Explanation
We are told that the
cost price of 18 apples = selling price of 16 apples
Let the cost price of an apple be x dollars
Let the selling price of an apple be y dollars
Buying 18 apples will cost 18 × x = (18x) dollars
Selling 16 apples will bring in 16 × y = (16y) dollars
Recall,
cost price of 18 apples = selling price of 16 apples
18x = 16y
We can rewrite as
16y = 18x
Divide both sides by 16
(16y/16) = (18x/16)
y = 1.125x
Percent gain is calculated as
[tex]\text{Percent Gain = }\frac{(\text{Selling price)-(Cost price)}}{Cost\text{ price}}\times100\text{ percent}[/tex]Selling price = y
Cost price = x
But recall that
y = 1.125x
[tex]\begin{gathered} \text{Percent Gain = }\frac{y-x}{x}\times100\text{ percent} \\ =\frac{1.125x-x}{x}\times100\text{ percent} \\ =\frac{0.125x}{x}\times100\text{ percent} \\ =0.125\times100\text{ percent} \\ =12.5\text{ percent} \end{gathered}[/tex]Hope this Helps!!!

SOLUTION
From the question,
Let x represent acres for apple orchard
Let y represent acres for peach orchard
Since the farmer can afford a maximum of 54 acres of land, that means
[tex]x+y\le54[/tex]The apple orchard requires 3000 gallons of water, while the peach requires 800 gallons of water. But the farmers irrigation system can deliver a maximum of 80,000 gallons per day, puting in an equation, we have
[tex]3000x+800y\le80,000[/tex]From his apple orchard, he expects to get a profit of $3,400 per year and from peach, a profit of $1,600 per year.
His expected profit will be determined using the equation
[tex]\begin{gathered} P=3400x+1600y \\ \text{where P is the expected maximum profit } \end{gathered}[/tex]So, we will plot the following points
[tex]\begin{gathered} x+y\le54 \\ 3000x+800y\le80,000 \end{gathered}[/tex]This will help us to get the required region needed to find the expected maximum profit
We can see that this is the same with graph B from the question
Now, we will substitute the following points from the graph into the equation of the maximum expected profit. Which ever that gives us the highest value becomes the answer.
For point (0, 54) we have
[tex]\begin{gathered} P=3400x+1600y \\ P=3400(0)+1600(54) \\ P=0+86,400 \\ P=86,400 \end{gathered}[/tex]For Point (16.727, 37.273), we have
[tex]\begin{gathered} P=3400x+1600y \\ P=3400(16.727)+1600(37.273) \\ P=56,871.8+59,636.8 \\ P=116,508.6 \end{gathered}[/tex]Finally, for point (26.667, 0) we have
[tex]\begin{gathered} P=3400x+1600y \\ P=3400(26.667)+1600(0) \\ P=90,667.8+0 \\ P=90,667.8 \end{gathered}[/tex]We can see that the maximum profit is $116,508.60, from
point (16.727, 37.273)
Hence the division of land that will maximize his expected profit is
16.73 acres of land for apple orchard
37.27 acres of land for peach orchard
Now, looking at the graph, the point (30, 20) lies outside the required region, so the farmer cannot maximize his profit at 30 acres for apple orchard and 20 acres for peach orchard.
Hence the answer is No, because the point (30, 20) lies outside the solution region.
