Alice took out an 80/20 mortgage on a $232,000 home. What is the amount
financed under the first mortgage?
Answer:
B. $185,600
Step-by-step explanation:
80/20 mortgage means pay 20% down payment and 80% finance amount of home value.
Home value = $232,000
Now, we need to find finance amount from this hone value of $232,000
Let's calculate the 80% of $232,000 as finance amount;
Finance amount = 80% of 232000
Finance amount = 0.80 x 232000
Finance amount = 185,600
The shape has an area of 60 square inches. Find the value of x.
Answer:
The value of x is 12.
Step-by-step explanation:
Given that the area of triangle formula is A = 1/2×b×h where b represents base which is the x and h is height, 10 inches. So you have to substitute the following values into the formula :
[tex]area = \frac{1}{2} \times base \times height[/tex]
Let area = 60,
Let base = x,
Let height = 10,
[tex]60 = \frac{1}{2} \times x \times 10[/tex]
[tex]60 = 5 \times x[/tex]
[tex]5x = 60[/tex]
[tex]x = 12 \: inches[/tex]
Answer:
12 inches
Step-by-step explanation:
The area of a triangle can be found using the following formula.
a=(b*h)/2
We know that the triangle has an area of 60 inches squared. We also can see from the picture that the height is 10 inches, and the base is x inches.
a=60 inches^2
b= x inches
h= 10 inches
Substitute these values into the formula
60=(x*10)/2
Now, solve for x. To do this, get x alone. Perform the opposite of what is being done to the equation. Remember to perform everything to both sides of the equation.
x*10 is being divided by 2. The opposite of division is multiplication, so multiply both sides by 2.
2(60)=(x*10/2)2
2(60)=x*10
120=x*10
x is being multiplied by 10. The opposite of multiplication is division. Divide both sides by 10.
120/10=x*10/10
120/10=x
12=x
The base, or x, is 12 inches.

A theater group made appearances in two cities. The hotel charge before tax in the second city was $1500 lower than in the first. The tax in the staty was
10%, and the tax in the second city was 5%. The total hotel tax paid for the two cities was $600. How much was the hotel charge in each oty before tax?
Answer:
The Hotel charge without tax in first city is $3500 and The hotel charge before tax in the second city is 2000
Step-by-step explanation:
Let x be the hotel charge without tax in first city
We are given that The hotel charge before tax in the second city was $1500 lower than in the first.
So, Hotel charge without tax in second city =x-1500
Tax% in first city = 10%
So, tax in first city = 0.1x
Tax% in second city =5%
So, tax in second city = 0.05(x-1500)
We are given that The total hotel tax paid for the two cities was $600.
So,0.1x+0.05(x-1500)=600
0.1x+0.05x+75=600
0.15x=600-75
[tex]x=\frac{600-75}{0.15}[/tex]
x=3500
Hotel charge without tax in first city = $3500
The hotel charge before tax in the second city =x-1500=3500-1500=2000
Hence The Hotel charge without tax in first city is $3500 and The hotel charge before tax in the second city is 2000

Answer:
Step-by-step explanation:
Angles 153 and QRP are straight angles, and thus Angle QRP is
180 - 153, or 27 degrees.
The interior angles of the triangle must sum up to 180 degrees:
27 + (3y + 5) + (2y - 7) = 180.
combining like terms, we get:
5y - 25 = 180, or 5y = 155, or y = 31
Then Angle Q is 3(31) + 5, or 93
Angle P is 2(31) - 7, or 55, and
Angle QRP is 27 degrees (found earlier).

Can we combine different functions (quadratic, linear, exponential, cube root) into one piecewise function? If the answer is yes, then why?
Plzzzz help
Answer: yes, because it is useful to describe changes in the behavior of the thing we are describing.
Step-by-step explanation:
A piecewise function f(x) is a function that is "different" depending on the range of the values of x, this is for example:
y = x -----> if x < 0
y = x^2 ----- if x ≥ 0
This is used to represent changes in the behavior of the thing we are describing.
For example, suppose an object that is moving with constant velocity, the velocity graph will be a constant line.
Now, the object suddenly, at a time t = t0 accelerates to a constant acceleration A, now the graph of the velocity is a linear graph with slope equal to A.
So this situation can be represent this with a piecewise function:
V(t) = c -----> if t < t0
V(t) = c + A*t -----> if t ≥ t0
So the answer is yes, we can.

ceipts for admission totaled $985.00. How many children and how many adults swam at the public pool that day?
mere were 159 children at the public pool.
Answer:
Step-by-step explanation:
Let the number of children = c
The number of adults = a
Total people = 528
c + a = 528 ------------------------(I)
Total price = $ 985
1.25c + 2.25a = 985 ---------(II)
Multiply equation (I) by (-1.25).
(I)*(-1.25) -1.25c - 1.25a = - 660
(II) 1.25c + 2.25a = 985 {add, c will be eliminated}
a = 325
Number of adults = 325
Plugin the value of a in equation (I)
c + 325 = 528
c = 528 - 325
c = 203
Number of children = 203

2x^2 - 28 = x^2 + 15
What is the answer!
Answer:
x = ± sqrt(43)
Step-by-step explanation:
2x^2 - 28 = x^2 + 15
Subtract x^2 from each side
2x^2-x^2 - 28 = x^2-x^2 + 15
x^2 -28 = 15
Add 28 to each side
x^2 - 28 +28= 15+28
x^2 = 43
Take the square root of each side
sqrt(x^2) = ± sqrt(43)
x = ± sqrt(43)
Use the table to find the constant of proportionality and the equation that represents the relationship. Let x = number of apples and y = number of slices. The constant of proportionality is _______. The equation for this relationship is _______.
THE ANSWER CHOICE IS IN THE PICTURE
Answer:
a)The constant of proportionality is 6.
b)The equation for this relationship is y=6x.
Step-by-step explanation:
a) 6/1=6
b)if apples is "x" and slices is "y," substitute y for 6 and x for 1
so 6=6(1) which is y=6x
The required constant of proportionality is 6 and the equation for this relationship is y=6x.
A table of data is given which describe the relationship between number of apples and number of slices. Blank space in statement to be filled.
The equation is a function of the relation between two or more values contains equal sign.
Here, from table the equation can be calculated as
Number of apples(x) is directly proportional to the number of slices(y). i.e.
y ∝ x
Now,
y=kx ----(1) (where k is proportionality constant)
for 1 apple the number of slices is 6 so,
6 = k*1
k = 6
Put k is equal to 6 in the equation (1).
y = 6x.
Thus, the required constant of proportionality is 6 and the equation for this relationship is y=6x.

Answer:
The area of rectangle A is length x breadth
= 3x5
= 15 units^2
The area of square B is side x side
= 3x3
= 9 units^2
Therefore,
The area of the rectangle is not double of the area of the square because 9x2 is not equal to 15. Steven isn't correct.
Answer:
a) Steven is incorrect.
b) Steven is incorrect, because he claims that, in other words, 15 units squared = 18 units squared. 18 > 15, so the statement that 15 = 18 is false. 15 does not equal 18.
Step-by-step explanation: Steven claims that the area of rectangle A is double the area of square B. The area of rectangle A is 15 units squared, because you get a product of 15 when you multiply the side lengths 5 and 3. The area of square B is 9 units squared, because you get a product of 9 when you multiply the side lengths 3 and 3. In other words, Steven is claiming that the area of rectangle A is not 15 units squared, but 18 units squared (this is double the area of square B, as 18 is the product of 9 and 2), and that statement is false, because we know that 18 > 15. Therefore, 18 cannot equal 15; the figure that is made from the value of double the area of square B (18 units squared) is larger than rectangle A (15 units squared) - this reinforces the fact that 18 > 15, and hence cannot be equal to 15.

Answer:
There is 20 dollars and the cost is 1.29. You need to have more money than the cost
To see if he can buy Y many songs
20 > 1.29 x Y
If you want how many songs
20/1.29=amount of songs
20/1.29 = 15.5

Answer:
B.
Step-by-step explanation:
(x-1)2+(y+2)2=4.
because the equation is shown in the graph
the equation of the circle with a center at (-1, 2) and a radius of 2 is:
(x + 1)² + (y - 2)² = 4
From graph er can see that center of circle is (-1,2) and radius is 2
The equation of a circle with its center at point (h, k) and radius r is given by:
(x - h)² + (y - k)² = r²
In this case, the center of the circle is (-1, 2), and the radius is 2. Plugging these values into the equation, we have:
(x - (-1))² + (y - 2)² = 2²
Simplifying further:
(x + 1)² + (y - 2)² = 4
Expanding the square terms:
x² + 2x + 1 + y² - 4y + 4 = 4
Combining like terms:
x² + y² + 2x - 4y + 1 + 4 - 4 = 0
Simplifying:
x² + y² + 2x - 4y + 1 = 0
Therefore, the equation of the circle with a center at (-1, 2) and a radius of 2 is:
(x + 1)² + (y - 2)² = 4
