PLEASE HELP

Answers

The answer is B all the others basically go into positive

The correct answer is B:

A cannot be right because -10 -1 is -11

B has to be right because -10 + 1 is -9

C cannot be right because 10 - 1 is 9, but it’s positive

D cannot be right because 10 + 1 is 11

Remember if you have 2 negatives it’s positive, and if you have 1 negative and 1 positive it’s negative

If the perimeter is 20 what must be the length of the missing side length? (Answer with Number Only) *

Answers

Answer:

8

Step-by-step explanation:

Perimeter = Sum of all side lengths

If perimeter = 20, then 5 + 3 + 4 + x = 20

( where x = missing side length )

5 + 3 + 4  = 12

12 + x = 20

20 - 12 = 8

Hence, x = 8

The answer would be 8
Step by step
5+3= 8
8+4=12
20-12=8

To avold a storm, a passenger-jet pilot descended 0.44mile in 0.8 minute. What was the plane's average change of altitude per minute?

Answers

Descends 0.55 miles per minute
Answer:
in order to find the answer you have to divide 0.44 by 0.8
when you divide decimals, the number that goes outside needs to be a whole number so it has to be 8
since you moved the decimal you also have to move the decimal from the inside. If you move the decimal it is going to be 4.4
so now you divide those numbers. 4.4/8

Sandra saves 10% of her salary for retirement. This year her salary was $1,000 more than in the previous
year, and she saved $4,200. What was her salary in the previous year?

Answers

Answer:

$41000

Step-by-step explanation:

If her salary was $1,000 more than the previous year and she save $4,200, $4,200 was 10% of her salary. So we should create an equation. (x being her salary from the previous year)

0.1(x+1000)=4200 (divide 4200 by .01)

x+100=42000

42000-1000= 41000

$41000 sorry if i am wrong :(

The formula for any geometric sequence is an = a1 · rn - 1 , where an represents the value of the n th term, a1 represents the value of the first term, r represents the common ratio, and n represents the term number. What is the formula for the geometric sequence 4, 8, 16, 32, ...?

A. an = 4 · (1/2) n - 1
B. an = 2 · 4 n - 1
C. an = 32 · 2 n - 1
D. an = 4 · 2 n - 1

Answers

Answer: The correct answer would be

D. an = 4.2n-1

Step-by-step explanation: First, calculate the ratios between each term and the one that precedes it.

8/4=2 ....16/8=2...32/16= 2...

Upon comparing the ratios we see the ratio between each term and the one that precedes it is 2 for all the terms, the sequence is geometric, and the common ratio is r = 2.

Now, we simply need to find the other unknown values in the equation, a1= the first term of the sequence which is 4, Therefore a1=4

Looking at the options provided we see that no further missing quantity can further be found so we put this in the equation provided for a geometric sequence.

We get 4. 2n-1, which is our answer.
