Pauline Romer has taken a $100000 mortgage loan on her house at an interest rate of 3 percent per year. If the mortgage calls for 20 equal annual payments, what is the amount of each payment?
Answer:
5000
Step-by-step explanation:
Using the mortgage interest principle, the amount of equal payment to be made ls $8000
Mortgage payment = $100000
Interest rate = 3%
The total amount to repayed can be calculated thus :
Mortgage payment × interest rate × timeNumber of annual payments = 20
Total repayment = 100000(1 + (0.03 × 20))
Total repayment = 100000 + 60000 = $160,000
Amount of each payment = $160000 / 20 = $8000
Therefore, the amount to be repayed annually is $8000

An Eastbound train (E) traveling 95 mph and a Westbound train (W) traveling 110 mph leave the same train station at different times. After 4 hours, they are 4 00 miles apart. Which system of linear equations can be used to determine the time that each of the trains has been traveling?
Answer:
The system of linear equations that can be used to determine the time that each of the trains has been traveling is:
E + W = 4 ....... Equation 1
95 E + 110W = 400 ......Equation 2
Hence,
An Eastbound train has been travelling for = (E) = 2.67 hours
A Westbound train has been travelling for = (W) = 1.33 hours
Step-by-step explanation:
An Eastbound train (E) traveling 95 mph and a Westbound train (W) traveling 110 mph leave the same train station at different times. After 4 hours, they are 4 00 miles apart. Which system of linear equations can be used to determine the time that each of the trains has been traveling?
Speed = Distance/Time
Distance = Speed × Time
Let the time
An Eastbound train = (E)
A Westbound train = (W)
E + W = 4 hours ....... Equation 1
95mph × E + 110mph × W = 400 miles
95 E + 110W = 400 miles ......Equation 2
The system of linear equations that can be used to determine the time that each of the trains has been traveling is:
E + W = 4 ....... Equation 1
95 E + 110W = 400 ......Equation 2
E = 4 - W
We substitute 4 - W for E in Equation 2
95 (4 - W) + 110W = 400
380 - 95W + 110W = 400
Collect like terms
95W - 110W = 400 - 380
15W = 20
W = 20/15
W = 1.3333333333 hours
≈ 1.33 hours
E = 4 - W
E = 4 - 1.33 hours
E = 2.67 hours
Therefore,
An Eastbound train has been travelling for = (E) = 2.67 hours
A Westbound train has been travelling for = (W) = 1.33 hours

Steve opens a bank account. The amount, in dollars, in the account x weeks after the account is opened can be modeled by function f. If Steve has $5,000 in the account 20 weeks after the account is opened, which TWO of the following must be true?
The missing options are:
[tex]A.\ f(20) =5,000[/tex]
[tex]B.\ f(5000) = 20[/tex]
C. In the xy plane, point (20, 5,000) is on the graph y = f(x).
D. In the xy plane, point (5,000,20) is on the graph y = f(x)
Answer:
[tex]A.\ f(20) =5,000[/tex]
C. In the xy plane, point (20, 5,000) is on the graph y = f(x).
Step-by-step explanation:
Given
Represent amount with y and weeks with x
So, we have:
x = 20 when y = 5000
Required
Select 2 correct options
A point on a graph can be illustrated using [tex](x,y)[/tex]
So, when x = 20 and y = 5000 ----- given
[tex](x,y)[/tex] implies that:
[tex](x,y) = (20,5000)[/tex]
We got [tex](20,5000)[/tex] by substituting 20 for x and 5000 for y
From the list of given options, the above represented of (x,y) is illustrated in option C
Represent (x,y) as a function, we have:
[tex]y = f(x)[/tex]
Substitute values for x and y
[tex]5000 = f(20)[/tex]
Reorder
[tex]f(20) = 5000[/tex]
The above is illustrated in option A
Hence, A and C answers the question

Ruben can paint 6 1/2 square meters per hour at the same rate how many square meters can he paint in 2 1/2 hour.?
Answer:
The number of square meters that Ruben can pain in 2 1/2 hours is:
16 1/4m²
Step-by-step explanation:
a) Data and Calculations:
Number of square meters that Ruben can pain in one hour = 6 1/2m²
Therefore, every 1/2 half he can paint 3.25m² or 3 1/4m²
In two hours, he can pain 6 1/2m² * 2 = 13m²
Using the same rate, in 2 1/2 hours, he can pain =xm² (0r 13m² + 3 1/4m²)
x = 6.5 * 2.5
= 16.25
= 16 1/4m²
b) Since Ruben can paint 6 1/2m² in one hour, he can then paint more square meters, multiplied by 2.5 in 2 1/2 hours. This means that he will be doubling the square area he can paint in 2 hours and painting half of the square area in 1/2 hour's time, given his speed.
How many square meters can he paint in 2 1/2 hour is 65/4 square meters
Given:
Square meters per hour= 6 ½
Number of hours =2 ½
Let x represent how many square meters he can paint in 2 1/2 hour
First step is to convert the mixed numbers to improper fractions
6 ½= 13/2
2 ½ = 5/2
Now let determine how many square meters he can paint in 2 1/2 hour
x=(13/2)× (5/2)
x= 16.25 or 65/4
Inconclusion How many square meters can he paint in 2 1/2 hour is 65/4 square meters.

Answer:
a) base: 29.4377 cm
b) hypotenuse: 30.7827 cm
c) area: 132.470 cm²
d) perimeter: 69.2204 cm
Step-by-step explanation:
a) The mnemonic SOH CAH TOA reminds you that ...
Tan = Opposite/Adjacent
tan(17°) = (9 cm)/base
base = (9 cm)/tan(17°) = 29.4377 cm
__
b) The sine relation could be used in the same way to find the hypotenuse:
hypotenuse = (9 cm)/sin(17°) ≈ 30.7827 cm
However, we're instructed to use the Pythagorean theorem. So, we have ...
hypotenuse = √(base² +(9 cm)²) ≈ √(886.577 +81) cm ≈ 30.7827 cm
__
c) The area is half the product of the base and height:
A = 1/2bh
A = (1/2)(29.4377 cm)(9 cm) ≈ 132.470 cm²
__
d) The perimeter is the sum of side lengths:
P = base + hypotenuse + height
P = (29.4377 +30.7827 +9) cm = 69.2204 cm

How far will 25 N of force stretch a spring with a spring with a spring constant of 125 N/m?
Answer:
-0.656168ft
Step-by-step explanation:
If Spring force constant (k) is 125 N/m
And the force is (F) 25 N ,
then the spring displacement (Δx) -0.656168
Equation used:
Knowing Hooke's law, we can write it down it the form of a formula:
F = -kΔx
F is the spring force (in N);
k is the spring constant (in N/m); and
Δx is the displacement (positive for elongation and negative for compression, in m).
