Shelley purchased a home in Maryland Heights, MO, for $204,000. Her down payment was 20% of the cash price, and she obtained a mortgage for 20 years at 7%. What's Shelley's monthly payment?
Answers
where
[tex]P[/tex] is the payment
[tex]PV[/tex] is the present debt
[tex]r[/tex] is the interest rate in decimal form
[tex]n[/tex] is the number of payments per year
[tex]t[/tex] is the time in years
Since she paid 20% of the value of the home, [tex]PV=204000-(240000)20[/tex]%=163200
Now, to convert the interest rate to decimal form, we are going to divide the rate by 100% [tex]r= \frac{7}{100} =0.07[/tex]. Since we are finding Shelly's monthly payment and a year has twelve months, [tex]n=12[/tex]. We also know that [tex]t=20[/tex], so lets replace those values in our formula:
[tex]P= \frac{ \frac{r}{n}(PV)}{1-(1+ \frac{r}{n})^{-nt} } [/tex]
[tex]P= \frac{ \frac{0.07}{12}(163200)}{1-(1+ \frac{0.07}{12})^{-(12)(20)} } [/tex]
[tex]P=1265.29[/tex]
We can conclude that Shelly's monthly payment is $1265.29
colin has a square garden with an area of 97 square feet feet. what is the length of each side of the garden
Answers
The length of one side of Colin's square garden, which has an area of 97 square feet, is approximately 9.85 feet.
Explanation:Colin has a square garden with an area of 97 square feet. The area of a square is calculated by squaring the length of one side (Side length * Side length = Area). Therefore, to find the length of one side of the square when you know the area, you would take the square root of the area.
In Colin's case, the area of the garden is 97 square feet, so the length of one side would be the square root of 97, which is approximately 9.85 feet.

Find the area of the triangle. (round to the nearest whole number)
Answers
============================================================
Explanation:
Check out the attached image. I've added in points A through D. The points A,B,C are the vertices of the largest triangle. Point D is directly below point A, and point D is on segment BC.
To find the area of the largest triangle ABC, we need the base length BC, which is broken up into segments x and y
x = length from C to D
y = length from D to B
Let's find x first
Triangle ADC is a right triangle, so we can use the pythagorean theorem
a^2 + b^2 = c^2
x^2 + 15^2 = 17^2
x^2 + 225 = 289
x^2 = 289 - 225
x^2 = 64
x = sqrt(64)
x = 8
Follow similar steps to find y
a^2 + b^2 = c^2
y^2 + 15^2 = 25^2
y^2 + 225 = 625
y^2 = 625 - 225
y^2 = 400
y = sqrt(400)
y = 20
Therefore
BC = x+y
BC = 8+20
BC = 28
The base of the triangle ABC is BC = 28 units
b = base
b = 28
The height is AD = 15
h = height
h = 15
We can now find the area of triangle ABC
Area = b*h/2
Area = 28*15/2
Area = 420/2
Area = 210
The area of the triangle is 210 square inches
What are the solutions of the equation x^2 - 7x -8= 0? Complete the square.
Answers
x = 8 , − 1
the solutions to the equation [tex]\( x^2 - 7x - 8 = 0 \)[/tex] are ( x = 8 ) and ( x = -1 ).
To solve the quadratic equation[tex]\( x^2 - 7x - 8 = 0 \)[/tex]by completing the square, we follow these steps:
1. Move the constant term to the other side of the equation:
[tex]\[ x^2 - 7x = 8 \][/tex]
2. To complete the square, take half of the coefficient of ( x ) (which is -7), square it, and add it to both sides of the equation:
[tex]\[ x^2 - 7x + \left( \frac{-7}{2} \right)^2 = 8 + \left( \frac{-7}{2} \right)^2 \]\[ x^2 - 7x + \frac{49}{4} = 8 + \frac{49}{4} \][/tex]
3. Simplify the right side of the equation:
[tex]\[ x^2 - 7x + \frac{49}{4} = \frac{32}{4} + \frac{49}{4} \]\[ x^2 - 7x + \frac{49}{4} = \frac{81}{4} \][/tex]
4. Write the left side of the equation as a perfect square:
[tex]\[ \left( x - \frac{7}{2} \right)^2 = \frac{81}{4} \][/tex]
5. Take the square root of both sides to solve for ( x ):
[tex]\[ x - \frac{7}{2} = \pm \sqrt{\frac{81}{4}} \]\[ x - \frac{7}{2} = \pm \frac{9}{2} \][/tex]
6. Solve for ( x ) by adding [tex]\( \frac{7}{2} \)[/tex]to both sides:
[tex]\[ x = \frac{7}{2} \pm \frac{9}{2} \][/tex]
This gives us two solutions:
[tex]\[ x = \frac{7}{2} + \frac{9}{2} = \frac{16}{2} = 8 \]\[ x = \frac{7}{2} - \frac{9}{2} = \frac{-2}{2} = -1 \][/tex]
So, the solutions to the equation [tex]\( x^2 - 7x - 8 = 0 \)[/tex] are ( x = 8 ) and ( x = -1 ).

First multiply everything in parenthesis by the number outside of the parenthesis.

Since you can't add/subtract numbers with differing variables, 10a - 14b - 10 is your final answer.
Final answer:
To multiply 5 by the expression (2a-7b-2), each term inside the parentheses is multiplied by 5, resulting in the final expression 10a - 35b - 10.
Explanation:
To use the distributive property to multiply 5(2a-7b-2), multiply each term inside the parentheses by 5.
Multiply 5 by 2a which gives 10a.
Multiply 5 by -7b which gives -35b.
Multiply 5 by -2 which gives -10.
Now, combine these results to get the final expression: 10a - 35b - 10.

There are four red bicycle helmets in a bin. If a helmet is selected without looking, what is the probability that the helmet is red?
A 1/4
B 1/3
C 4/4
D 3/4
Answers
Given that all helmets in the bin are red, the probability of randomly selecting a red helmet is 1, which corresponds to answer C.
Explanation:The question is asking for the probability that a randomly selected helmet from a bin of four is red. Since all the helmets in the bin are red, no matter which one you pick, it will be red. In probability, this is represented as the total number of favorable outcomes divided by the total number of outcomes. In this scenario, both favorable outcomes (red helmets) and total outcomes (helmets in the bin) are four. Mathematically, 4/4 results in 1. So, the correct answer is C which symbolize the probability to be 1.

A line passes through the point (2, 3) and has a slope of -2. Which is the equation of the line in point-slope form?
Answers
The correct answer is option B: [tex]\( y = -2x + 7 \).[/tex] To write the equation of a line passing through the point (2, 3) with a slope of -2, we can use the point-slope form of a linear equation.
The point-slope form is given as:
[tex]\[ y - y_1 = m(x - x_1) \][/tex]
Where [tex]\( (x_1, y_1) \)[/tex] is a point on the line and [tex]\( m \)[/tex] is the slope.
Given that the point is [tex]\( (2, 3) \)[/tex] and the slope is [tex]\( -2 \)[/tex], we can substitute these values into the point-slope form:
[tex]\[ y - 3 = -2(x - 2) \][/tex]
Now, we can simplify and rewrite the equation in various forms to match the options provided:
Option A: [tex]\( 2x + y = 7 \)[/tex]
To match this option, let's rearrange the equation:
[tex]\[ y - 3 = -2(x - 2) \][/tex]
[tex]\[ y - 3 = -2x + 4 \][/tex]
[tex]\[ 2x + y = 7 \][/tex]
So, option A is equivalent to the given equation.
Option B: [tex]\( y = -2x + 7 \)[/tex]
Let's solve the equation for [tex]\( y \):[/tex]
[tex]\[ y - 3 = -2(x - 2) \][/tex]
[tex]\[ y - 3 = -2x + 4 \][/tex]
[tex]\[ y = -2x + 7 \][/tex]
This matches option B.
Option C: [tex]\( y - 3 = -2(x - 2) \)[/tex]
This is already in point-slope form and matches the given equation.
Option D: [tex]\( y = -\frac{1}{2} x + 5 \)[/tex]
Let's solve the equation for [tex]\( y \):[/tex]
[tex]\[ y - 3 = -2(x - 2) \][/tex]
[tex]\[ y - 3 = -2x + 4 \][/tex]
[tex]\[ y = -2x + 7 \][/tex]
This does not match option D.
Therefore, the correct answer is option B: [tex]\( y = -2x + 7 \).[/tex]
The complete question is:
A line passes through the point (2, 3) and has a slope of -2. Which is the equation of the line in point-slope form?
A) 2x + y = 7
B) y = -2x + 7

D) y = - 1 2 x + 5.
