B
13, 15, 17, 19

C
2, 5, 23, 29

D
3, 17, 29, 81

Answers

Answer 1
Answer: the answer is C because 2, 5, 23, and 29 are prime numbers (you can also look up a chart and highlighted numbers are prime). prime numbers is a whole number greater than 1 and cannot be formed when multiplying two smaller numbers that are whole. it must involve itself in a multiplication equation.

An airplane's altitude changed -378 feet over 7 minutes. What was the mean change of altitude in feet per minute?


WORK PLEASE

Answers

so which is equivilent
pemdas

(8-6x+12)
(20-6x)
multiply/distribute
1/4(20-6x)
5-6/4x=5-3/2x=-3/2x+5

the answer is D



so mean is equivilent to average

per minute means x feet for every one minute=xfeet/1miin=x/1

so just divide
-378/7=-54

mean change in altitude
-54 feet per minute
First Question:

(1)/(4)(8-6x+12) =
(8)/(4)-(6x)/(4)+(12)/(4) =
2-(3)/(2)x+3 =
\boxed{(D) -(3)/(2)x+5}

Second Question:

The average (mean) rate of change is just (-378)/(7) =\boxed{-54 ft/min}

Hope this helps :D

Find the term to term rules for the following sequence-

2,6,18,54,162

Answers

Answer:

Essentially, to find the next term in this sequence, the number must be multiplied by 3.

So, the term to term rules for this sequence would be N x 3

Answer:

a_n=2*3^(n-1)

Step-by-step explanation:

The formula for a geometric sequence is a_n=a_1*r^(n-1) where a_n is the nth term of the sequence, a_1 is the first term, and r is the common ratio.

Since each term is being multiplied by 3, this is our common ratio.

Therefore, our geometric sequence formula is a_n=2*3^(n-1)

If u add 125 times 8 it will equal 1000
becouse
8*125=1000
then
(1000)/(8) =125
you also can combine it (if this is what are you looking for..)
888+88+8+8+8=1000
or any other combination like:
88+888+8+8+8=1000

Mr. Levine corrects 7 tests in 25 minutes. At this rate, how long would it take him to correct 120 tests?

Answers

Answer:

428 4/7ths minutes

Step-by-step explanation:

Answer: 7 hours and 8 minutes

Step-by-step explanation:

7 tests in 25 minutes

7 divided by 25= 3.57

3.57 minutes per test times 120 tests= 428.57 minutes

428.57 divided by 60 (60 minutes in an hr) = 7 hours and 8 minutes (and 57 seconds if u want to count those too)
