Heather is planning to buy a home. She would need to borrow $200,000 from a bank over a 30-year period. The monthly payment is $1800. What will be her total interest for the 30 years?
Answer:
Below.
Step-by-step explanation:
Total payment = 1800 * 30 * 12 = 648,000.
Interest = 448,000.
Heather should have to pay total of $648,000 to the bank and Interest Heather will pay to the bank is $448,000.
What is interest?Interest is the price you pay to borrow money or cost you charge to lend money. Interest can be calculated by total amount you paid after a specific time period minus the total amount you borrowed.
Heather borrowed $200,000 from a bank over a period of time 30 year.
30 year = 12×30monts
=360 months
Now, The monthly payment to the bank is = $1800
Therefore total payments in 360 months is = 360×$1800
=$648,000
Bank Interest = $648,000 - $200,000
=$448,000
Hence , Heather total interest after 30 years will be =$448,000

if you doubled a recipe that makes 2 doz. cookies how many cookies would you expect to make
Answer:
48
Step-by-step explanation:
remember 1 dozen of something is 12 of that object
so 1 dozen cookies is 12 cookies
two dozen means two times one dozen
or 2-times twelve (because there are twelve of an object in a dozen)
2 times 12 is 24
now you double the recipe that makes 2 dozen cookies
so you have 24 cookies and you multiply that by 2 to double it and you get 48

What is the slope of a line perpendicular to the line in the graph?
Answer:
-[tex]\frac{2}{3}[/tex]
Step-by-step explanation:
Angle T and angle V are complementary angles. If cos T = 0.75, which statment is always true?
Complementary angles T and V would add up to 90 degrees
The true statement is sin V = 0.75
How to determine the correct statement?The given parameters are:
cos T = 0.75
Angles T and V are complementary angles
The second highlight above means that:
T + V = 90cos T = sin Vsin T = cos VSubstitute 0.75 for cos T in cos T = sin V
0.75 = sin V
Rewrite as:
sin V = 0.75
Hence, the true statement is sin V = 0.75

Amelia wants to paint 3 walls in her family room. Two walls are 26 feet long by 9 feet wide. The other wall is 18 feet long by 9 feet wide.
A. What is the total area of the walls that Amelia wants to paint?
B. Each gallon of paint covers about 250 square feet. How many gallons of paint should Amelia buy to paint the walls?
Answer:
x = 2.52 gallons. It is best that she buy 3 gallons of paint.
Step-by-step explanation:
Wall 1 & 2 : 26 ft by 9 ft
Wall 3 : 18 ft by 9 ft
Area 1 : 26 ft x 9 ft = 234 ft²
Area 2 : 26 ft x 9 ft = 234 ft²
Area 3 : 18 ft x 9 ft = 162 ft²
Total Area : 234 ft² + 234 ft² + 162 ft² = 630 ft²
1 Gallon = 250 ft²
630 ft² ÷ 250 ft² per gallon = 2.52 gallons
Amelia will need 2.52 gallons of paint to cover the wall space of 630 ft^2

find the slope and the y-intercept for the graph of y = -4.
a -4;none
b 1;-4
c 0; -4
d -4;0
thank you for the help
Answer:
C, 0;-4
Step-by-step explanation:
y=-4 means that no matter what the x value is, the y value will ALWAYS be -4. It does not change based on what x is, and we can tell that just by looking at it because x isn't even in the equation. I've attached an image of that the graph would look like.
The slope of the graph references how many units the y value increases for each increase in the x value. For example, a slope of 1/2 means that each time the x value increases by 2, the y value would increase by 1. But because y's value never changes, the slope is 0. No matter how much the x value changes, the increase in y values will be 0.
Since the y-axis is at where x=0, the y-intercept basically asks, "What is y's value when x is 0?" But like I mentioned before y's value never changes. It's always -4, no matter what the x value is. Therefore, the y-intercept is at -4.

Is the vertex maximum or a minimum
Step-by-step explanation:
In this case the vertex is a maximum since it's in the shape of a hill not a valley. Vertex is (0,4)
Answer:
Maximum
Step-by-step explanation:
It is the maximum of the graph because it is the highest (MAXIMUM) point on the graph that the line reaches. If it were upside down, and the vertex was at the bottom and was the lowest point of the line, then it would be the minimum.
Divide (6x3y2 + 12x2y - 8xy) by (2xy)
Answer:
Step-by-step explanation:
6x³y² = 2 * 3 * x³ * y²
12x²y = 2 *3 * 2 * x² * y
8xy = 2 * 2 * 2 *x * y
GCF = 2xy
6x³y² + 12x²y - 8xy = (2xy * 3x²y) + (2xy * 6x) - (2xy * 4)
= 2xy *(3x²y + 6x - 4)
[tex]\dfrac{6x^{3}y^{2}+12x^{2}y-8xy}{2xy}=\dfrac{2xy*(3x^{2}y+6x-4)}{2xy}\\\\\\= 3x^{2}y + 6x - 4[/tex]
write each equation in slope-intercept form (3,4); and (-6,-2)
Answer:
y = 2/3x + 2
Step-by-step explanation:
Slope intercept form is y=mx+b where m is the slope and b is the y intercept.
Given 2 points you can find the slope using (y-y1)/(x-x1)
m = (-2-4)/(-6-3) = -6/-9 = 2/3
To find b use one of the points and m and plug into the slope intercept form and then solve for b.
y=mx+b
4=2/3(3) + b
4=2 + b
b=2
Now we can write the final equation as : (plug m and b back in)
y = 2/3x + 2
To write in slope-intercept form, we must first find the slope.
[tex]Slope = \frac{y2-y1}{x2-x1} =\frac{4-(-2)}{3-(-6)} =\frac{6}{9}=\frac{2}{3}[/tex]
Now lets put into the point-slope form which requires the use of any one of the two points given which in this case can be (3,4) and the slope 2/3
[tex]y - y_{0} =m(x-x_{0} )\\y-4=\frac{2}{3} (x-3)\\[/tex]
Now to put into the slope-intercept form, we must solve for y:
[tex]y - 4 = \frac{2}{3} x -2\\y = \frac{2}{3} x +2[/tex]
Hope that helps!
