Please help, what’s the perimeter? I got the answer wrong I need the correct answer, A, C, or D?
balandron [24]
The answer is C. The square root of 83 is about 9.1. Because a square has four sides, you multiply 9.1 by 4 to get 36.4. The product rounds to the nearest whole number at 36.

Tom Burke buys a home in Virginia for $139,000. He puts down 30% and obtains a mortgage for 25 years at 12%. The portion of the
Marat540 [252]
You didn't specify the periodic payment in your question. I will solve it assuming that payment is made monthly.

Amount owing by Tom = 70% of 139,000 = 0.7 x 139,000 = $97,300

Present Value of an annuity is given by PV = P(1 - (1 + r)^-n)/r; where P is the periodic (monthly) payment, r is the interest rate = 12%/12 = 1% = 0.01, n is the number of periods = 25 x 12 = 300 months.

97,300 = P(1 - (1 + 0.01)^-300)/0.01
P = 973/(1 - (1.01)^-300) = 973/(1 - 0.050534) = 1,024.79
Thus Tom pays $1,024.79 per month.

Interest due for the first month = 0.01 x 97,300 = $973

Therefore, the portion of the first payment that covers the interest is $973

Answer:

The Equation is

10 + c = 3

Solution c = -7

Step-by-step explanation:

Given:

Word Sentence is

10 more than a number c is 3

means

10 more extra with a number c ∴ it will be 10 + c

then it is saying after 10 more than a number c it is 3

i.e the whole number  is equal to 3

∴ 10 + c = 3       is the required Equation

∴    c = 3 - 10

∴    c = -7         is the required solution

The Equation is

10 + c = 3

Solution c = -7
