Amy got a $1,000 loan from her bank, and she had to repay $1,550. What are the principal and interest amounts in this transaction?

Answers

Answer 1

Answer:

Answer:

Principal = $ 1,000

Interest = $ 550

Step-by-step explanation:

Given,

The total amount of the loan = $ 1,000

Since, the amount of the loan is called principal amount of the loan,

Thus, principal amount of the loan is $ 1,000

Now, the amount she return = $ 1,550,

Hence, the interest she paid = amount returned - principal amount

= $ 1550 - $ 1000

= $ 550

Answer 2

Answer: the principal is $1,000 and the interest is $550.

Two possible factors for the estimated product of 2800

Answers

100 and 28.

Explanation

Factors are number that you can multiply to give a certain number.

For example, 2 × 3 = 6. In this case 2 and 3 are factors of 6.

∴ To get the factors of 2800, we have to find numbers that you can multiply to give you 2800.

2800 / 2 = 1400

∴ 2 × 1400 = 2800. ⇒ 2 and 1400 are factors of 2800.

2800/100 = 28

∴ 100 × 28 = 2800 ⇒ 100 and 28 are also factors of 2800. 2800 have many factors but two of them are 100 and 28.

What is the value of st ÷ (6r) if r = 5, s = 32, and t = 45?

Answers

Answer: The answer is 48.

Step-by-step explanation: The given expression is

$E=st/6r.$

we are given to solve the above expression is the value of r is 5, the value of s is 32 and the value of t is 45.

The solution is as follows:

$E\n\n=st/6t\n\n=(st)/(6r)\n\n=(32* 45)/(6* 5)\n\n=16* 3\n\n=48.$

Thus, the required value is 48.

st ÷ 6r
(32)(45) ÷ 6(5)
1440 ÷ 30
48

What is A2 – (B + C) in simplest form?A=8x2 – 25x + 7
B=8x2– 25x + 11
C=10x2 – 25x + 7
D=10x2 – 25x + 11

A, B, and C are polynomials, where:
A = 3x – 4
B = x + 7
C = x2 + 2

Answers

A2 - (B + C) = (3x - 4)2 - ((x + 7)+ (x2 + 2))
A2 - (B + C) = 9x2 - 24x + 16 - (x2 + x + 9)
A2 - (B + C) = 9x2 - 24x + 16 - x2 - x - 9
A2 - (B + C) = 8x2 - 25x + 7

So, the answer is
A:
8x2 – 25x + 7

Answer: $8x^2 - 25x + 7$
