Why the order of a succession is important

Answers

Answer:

Step-by-step explanation:

The order of a succession is a way that the terms (the first, the second, the third, etc.) can be distinguished according to a certain formation law or order criterion.

In the order of a sequence you can assign any letter.

Jeremy is 5 years younger than his older sister. His older sister is 9 years older than his younger sister. The total of their age is 49. Write and solve an equation to find the ages of Jeremy and his sisters. I need help please!

Answers

Jeremy=x
Older sister=x+5
younger sister=x+5-9 or x-4
x+(x+5)+(x-4)=49
combine like terms
3x+5-4=49
3x+1=49
subtract 1 from both sides
3x=48
divide both sides by 3
x=16
Jeremy=16
Older sister=16+5=21
younger sister =16-4 or 16+5-9=12
J=16
OS=21
YS=12
Jeremy - x
Older sister - x+5
Younger sister - x-4
3x+1=49
3x=48
X= 16

Jeremy: 16
Older sister: 21
Younger sister: 12

C: Add only the rent/mortgage and utility expenses.
D: Estimate that it will be about 20% of your net income.

A: Multiply it by 2, then round
B: Round it down to $650, then multiply by 2
C: Add it to other estimates just as it is
D: Multiply it by 4, then round (my answer)

3. Rent is $978. Phone charges last month were $54.89. Groceries cost about $93/week. What is a good estimate of your monthly expenses?

Answers

1. If I remember from class correctly, your monthly expenses should be about 20% of your net income, so the answer would be D. Although, adding up the expenses would work as well.
2. If the payment is bi-weekly, and there are 4 weeks in a month, you only have to multiply by 2, because "bi-weekly" means every 2 weeks, which means the payment would come twice a month. So, the answer would be A, Multiply by 2 and then round.
3. Round each of the numbers. 978 becomes 980, 54.89 becomes 55, and 93 becomes 90. We'll assume that there are 4 weeks in a month. Add them all up. 980+55+90+90+90+90 = 1395  So, yes, your answer of D, 1,400.00 is a good estimate.
4. Again, round each of the numbers. 455 can stay the same, 34.95 becomes 35, 65.88 can stay at 65 for the sake of easy math, and 87 gets rounded up to 90.
We'll keep assuming that there are 4 weeks in a month. Now, add them all up. Be sure to remember that the rent is bi-weekly, so it has to be added in twice. 455+455+35+65+90+90+90+90 = 1370. This means that of the choices, D, 1,359.00 is a good estimate of the monthly expenses.

A professor determined the relationship between the time spent studying (in hours) and performance on an exam. Performance = 70.443 + 4.885 * (time) Ann studied 2.6 hours for the last exam. However there was a concert in town the night before and her score was 16 points lower than expected. What was her score on this exam, rounded to the nearest integer?

Answers

First we need to calculate Ann's predicted score.

Predicted Score = 70.443 + (4.885)(2.6)

Ann's predicted score was 83.114

Since her actual score was 16 points lower than this, we just subtract.

Real Score = 83.114 - 16

Ann's real score was 67.114

When rounded to the nearest interger Ann's score is 67

Not really sure how to find xy :(

Answers

that's an equilateral triangle which means that all sides and angles are equal to each other. So now if you set everything equal to each other you get 2(2x+1)=6x+7y. Now it's just algebra after that, you have to distribute then left side then isolate the variable y and you get a y value. next step is pretty simple just substitute the answer that you got for y into the original equation that included y so you can get an x value. if everything is right it should tell you that the final answer is 14.
