If Bobby takes out a mortgage for 30 years at an interest rate of 4% and his monthly repayments are $835.48, what is the principal loan amount?
Round your answer to the nearest ten dollars.
Do NOT round until you have calculated the final answer.

Answer:

Step-by-step explanation:

Note - Since you have given multiple questions to solve, I will solve the first question for you. To get any particular question solved, please specify the question.

1) 

To calculate Tom's monthly mortgage payments, we can use the formula for a fixed-rate mortgage payment, which is:

M = P.r.(1+r)^n / [ (1+r)^n - 1]

Where:

M is the monthly payment

P is the principal amount (the remaining property value after the deposit)

r is the monthly interest rate (annual interest rate divided by 12 months)

n is the total number of payments (number of years multiplied by 12 months)

Given:

Property value (P) after the deposit: $300,000 - (0.25 * $300,000) = $225,000

Annual interest rate (r): 2%

Number of years (n): 25 years

First, calculate the monthly interest rate (r) by dividing the annual interest rate by 12:

r=2% / 12 ​=0.02/12=0.001667

Next, calculate the total number of payments (n):

n=25 years×12 months/year=300 monthsn=25 years×12 months/year=300 months

Now, plug these values into the mortgage payment formula:

M=$225,000 x 0.001667x (1+0.001667)^300​  / [(1+0.001667)^300−1]
 

Calculating this expression will give us Tom's monthly mortgage payment: M≈$963.96

So, Tom's monthly mortgage payment will be approximately $963.96 when rounded to the nearest cent.

For every 8 cars there are 7 trucks

Therefore,

Cars:Truck=8:7

Answer is B)8:7

y=2x+15

where y=Value of coin

x=Age in years

Value of coin after 19 years=2*19+15

=$53

Therefore, Value after 19 years=$53

Speed=Distance/time

Here,

distance=15m

time=1sec

speed=15/1=15m/sec

Distance=Speed*time

time=15min=15*60sec=900sec

Distance travelled in 15 min=15*900=13,500m

=13500/1000 km=13.5Km

The wood before starting =12 feet

Left wood=6 feet

Wood used till now=12-6=6 feet

Picture frame built till now= 6/(3/4)

=8 pieces

Therefore, till now 8 pieces have been made.

Area of rectangle= L*b

here,

L=12.4 cm

b= 8.8 cm

A= L*b

= 12.4 * 8.8 = 109.12 cm^2

Volume of rectangular prism=length * width * height

Given,

length=3/8cm

breadth=5/8cm

height=7/8cm

therefore volume=(3/8)*(5/8)*(7/8)

                           =105/512 cm3

The answer is in the image 

Cost of 6 gallons =$15

Cost of 1 gallon =15/6

                           =$2.5

Cost of 7 gallons=$2.5 * 7

                           =$17.5

We can put the numbers in ascending order-

36, 38, 39, 39, 40, 47, 48, 51

Range=max-min

          =51-36

          =15
