Susan is paying $0.30 per $100 on her $483,000 home in homeowners insurance annually. If her annual homeowners insurance premium is divided into twelve equal monthly installments to be included on each of her monthly mortgage payments of $2128.00, what is her total monthly payment? a. $2,248.75 b. $2,409.75 c. $3,381.00 d. $3,577.00 Please select the best answer from the choices provided
Answer:
a) $2248.75
Step-by-step explanation:
Susan pays $0.3 per $100
For $483000, she pays $1449 insurance annually : Calculation shown below
483000/100 x 0.3 = $1449
Monthly instalments of the insurance premium for 12 months :
annual insurance premium/ 12 months
1449/12 = $120.75
Monthly mortgage payments = $2128
Monthly total payments = monthly mortgage payments + monthly insurance premium instalment.
= 1449 + 120.75
= $2248.75

Sara sells beaded necklaces she makes a profit of 4 dollars pn every neclace she sells which table represents the profit sara makes
if you multiply the number of necklaces sold by 4 for all 4 values in the first column of the table then you should get the value in the second column of the table
Table {4} represents the correct function that represents the profit function.
What is function?A function is a relation between a dependent and independent variable. We can write the examples of function as -
y = f(x) = ax + b
y = f(x, y, z) = ax + by + cz
Given is that Sara sells beaded necklaces she makes a profit of 4 dollars every necklace she sells.
Assume that she sells {x} necklaces in total. So, we can write the function for Sara's profit as -
y = 4x
We can see that table {4} is represented by the profit function.
Therefore, table {4} represents the correct function that represents the profit function.

What is the result when the number 25 is decreased by 20%?
Answer:
20
Step-by-step explanation:
100% - 20% = 80%.
80% of 25 = 25 x 0.8 = 20
When the number 25 is decreased by 20%, the result is 20.
Explanation:To find the result when the number $25 is decreased by 20%, we need to calculate 20% of 25 and subtract that from 25.
20% of 25 is (20/100) x 25 = 5.
Subtracting 5 from 25, we get the result as 20.

ivanna's earnings vary directly with the number of hours she works. suppose that she worked 7 hours yesterday and earned $77. if she earned $99 today, how many hours did she work today
Answer:
9 hr
Step-by-step explanation:
vary directly means you should think about a constant being multiply to one variable to get another variable.
So we have E=kH
where E=earnings and H=hours and k is the constant of proportionality
So they give us when H=7 we have E=77 giving us 77=k(7) which means the constant of proportionality is 11
So that means no matter what the E and H are k is 11
So we have the equation is E=11H
Replace E with 99 and solve for H
99=11(H)
So H=9
9 hours
Kevin is responsible for delivering sacks of grains to a grocery shop on the tenth floor of a departmental store. Each sack weighs 364 pounds and Kevin weighs 150 pounds. The capacity of the elevator is 2,000 pounds.
If six sacks are to be taken at a time, what should be the weight of each sack?
Final answer:
Kevin can safely take sacks weighing up to 308.33 pounds each in the elevator, provided he takes six sacks at a time and the elevator's capacity is 2,000 pounds with Kevin weighing 150 pounds.
Explanation:
The student's question is asking for the maximum weight of each sack of grain that Kevin can deliver on the elevator, given the elevator's weight capacity and the additional weight of Kevin himself. To answer this question, we need to consider the weight that the elevator can hold minus Kevin's weight, and then determine how much weight is left for the sacks of grain.
The elevator has a capacity of 2,000 pounds, and Kevin weighs 150 pounds. This means the total weight that the elevator can carry in addition to Kevin is:
2000 pounds (elevator capacity) - 150 pounds (Kevin's weight) = 1850 pounds (available for sacks)
If Kevin needs to deliver six sacks at a time, we can divide the total available weight by six to find the maximum weight for each sack:
1850 pounds / 6 sacks = approximately 308.33 pounds per sack
Therefore, the weight of each sack must be 308.33 pounds or less for Kevin to safely use the elevator without exceeding its capacity.
Solve for z :2x+6yz=2xz+2y
Answer:
z = [tex]\frac{y-x}{3y-x}[/tex]
Step-by-step explanation:
2x+6yz=2xz+2y (rearrange so that z is on one side)
6yz - 2xz = 2y - 2x (divide both sides by 2)
3yz - xz = y - x (factor our z from LHS)
z (3y - x) = y - x
z = [tex]\frac{y-x}{3y-x}[/tex]
What is the value of b for the following circle in general form?
x^2+y^2+ax+by+c=0
Answer:
a = -2 and b=4 and c = -4
Step-by-step explanation:
the center is : A(1 ; -2)
B(1 ; 1) in this circle so ; AB= r ( ridus)...r =3
note :
an equation of the circle Center at the A(1,-2) and ridus : r is :
(x-1)² +(y+2)² = 3²
x²-2x+1 +y²+4y +4-9 =0
x²+y² -2x+4y -4 = 0 so : a = -2 and b=4 and c = -4

Answer:
-2 + i
Step-by-step explanation:
v = -3i
w = 2 - 4i
v - w =
= -3i - (2 - 4i)
= -3i - 2 + 4i
= -2 + i
The given value of v = -3i and w = 2-4i, so v-w = -2 + i.
Given: v = -3i, w = 2-4i
To find: v - w
Solution:
Substitute the values of v and w into the expression v - w.
v - w = -3i - (2-4i)
v - w = -3i - 2 + 4i
v - w = -2 + i

rate is 6.25%, what is the amount of
sales tax?
A $0.48
B $2.19
C $4.75
D $474.94
Step-by-step explanation:
75.99 ×.0625=4.749
75.99+4.75(because I rounded)=
$80.74 total cost incase you have another step
75.99 ×.0625 = 4.749
I rounded to get 4.75.
75.99 + 4.75 = $80.74
$80.74 - $75.99 = $4.75
Answer: $4.75
What is the value of x?
[tex]x+40=3x\\2x=40\\x=20[/tex]
For this case we have by definition of angles between secant lines that:
[tex]x + 40 = 3x[/tex]
Also, the angle between T and V is equal to the angle between S and W.
Returning to the question, we have to:
[tex]x + 40 = 3x[/tex]
We must know the value of "x":
Subtracting 3x on both sides of the equation we have:
[tex]x-3x + 40 = 0[/tex]
Subtracting 40 from both sides of the equation:
[tex]-2x = -40[/tex]
Dividing between -2 on both sides of the equation:
[tex]x = \frac {-40} {- 2}\\x = 20[/tex]
So, the value of x is 20
Answer:
[tex]x = 20[/tex]
find (fof)(0) f(x)=x^2
a.1
b.0
c.-8
d.-1
Answer:B
f(0)=0
Step-by-step explanation:
when 0 is squared it’s just 0
Answer: option b.
Step-by-step explanation:
Given the function f(x):
[tex]f(x)=x^2[/tex]
In order to find [tex](fof)(x)[/tex], the first thing you must do is to substitute the function f(x) into the same function f(x). Observe the procedure:
[tex](fof)(x)=(x^2)^2[/tex]
Now, you need to simplify:
[tex](fof)(x)=x^4[/tex]
Finally, to find [tex](fof)(0)[/tex] you need to substitute [tex]x=0[/tex] into [tex](fof)(x)=x^4[/tex], then you get:
[tex](fof)(0)=(0)^4[/tex]
[tex](fof)(0)=0[/tex]
8x=2y+5
3x=y+7
what is the solution ?
Answer: (4.5, 6.5) is your solution
Step-by-step explanation:
You need either the x term or the y term to be the same in both equations so you can eliminate them...
8x=2y+5
6x=2y+14
Now you can subtract the two equations...
2x=9
Divide 9 by 2....
x=4.5 or 4 1/2
Plug in x into one of the original equations to find y...
13.5=y+7
Subtract 7 from 13.5...
6.5=y

What is the slope of the equation y - 3 = -4(X - 5)?
Answer:
Step-by-step explanation:
y - 3 = -4(x - 5)
Add 3 to both sides to isolate y
y = -4 ( x - 5 ) + 3
Distribute
y = -4x +20 + 3
Combine like terms
y = -4x + 23
y = mx + b is standard form for which m is slope
m = -4
Please mark for brainliest!! :D Thanks!!
If you have any questions or need more information, please comment below and I'll respond asap!!
Answer:
-4
Step-by-step explanation:
Distribute -4 into the parenthesis and get -4x + 20. The number paired with x is the slope, usually represented by m in y = mx + b. So, the slope is -4. For the full slope intercept format, move the -3 on left side to the right by adding 3. The new equation is y = -4x + 23.
Which expression is equivalent to sqrt10/4sqrt8
Answer:
Step-by-step explanation:
Since it's a division we need to look for a common factor to cancel
so first we try to break the numbers to there prime factors
[tex]\frac{\sqrt{10} }{4\sqrt{8} } = \frac{\sqrt{2.5} }{4\sqrt{2.2.2} }[/tex]
So , now we try to factors that are common in top and bottom
[tex]= \frac{\sqrt{2} \sqrt{5}}{4\sqrt{2}\sqrt{4} }[/tex]
common factor is sqrt 2 so lets cancel it
we get
[tex]\frac{\sqrt{5} }{4\sqrt{4} }[/tex]
[tex]\frac{\sqrt{5} }{8}[/tex]
