Answer:

(E) 27

Step-by-step explanation:

Let the 5 digit palindrome be PQRQP

Since each digit is chosen from 1,2,3 therefore

P can either be 1,2 or 3 which gives us 3 options.

Q can also either be 1,2 or 3 which gives us 3 options

R can either be 1,2 or 3 which also gives us 3 options

So we have 3^3 = 3*3*3

= 27

This means 27 palindromes are possible if they are formed using one or more of the digits, 1, 2, 3.

Again one question not two
Anettt [7]

Answer: A) 5m = 50; m = 10

Step-by-step explanation:

The diagram shows 5 "m"s, or 5*m equal to 50.  Thus, 5m=50.

Because 5m = 50, divide both sides by 5 to get that m = 10

KATRIN_1 [288]

Answer:

a.) $29,750.00   simple interest

b.) $75,266.35  Compounded annually

c.) $79,358.65 compunded  quarterly

d.) $80,332.11 compounded monthly

Step-by-step explanation:

a.) Formula: I = p x r x t

Where:

P is the principal amount, $17000.00.

r is the interest rate, 7% per year, or in decimal form, 7/100=0.07.

t is the time involved, 25....year(s) time periods.

So, t is 25....year time periods.

To find the simple interest, we multiply 17000 × 0.07 × 25 to get that:

The interest is: $29750.00

Choose Yes or No to tell whether the expressions are equivalent. 1. 4(5c + 3) and 9c + 7 yes or no 2. 10f – 10 and 2(8f – 5) yes
Juli2301 [7.4K]

Answer:

1) No

2) No

3)Yes

4)No

Step-by-step explanation:

Distributive property: a(b + c) =a*b + a*c

1) 4(5c + 3) = (4*5c) + 4*3

                  = 20c + 12

NO

2) 2(8f - 5) = (2*8f) - (2*5)

                 = 16f - 10

NO

3) 3(4g + 7) = (3*4g) + (3*7)

                  = 12g + 21

YES

4) 6(4j - 6) =(6 * 4j) - (6*6)

                = 24j - 36

NO
