Kelly is saving her money to buy a car. She has $250, and she plans to save $75 per week from her job as waitress.a. Model the situation using an arithmetic sequence.

b. How much will kelly have saved after 8 weeks?

c. If the car costs $2000, how long will it take her to save enough money at this rate?

Please someone help me.

Answers

Answer 1

Answer: so she is essentially saving 250+n*75, where n is the number of weeks.

after 8 weeks she will have 250+8*75, (you need to substitute n for the number of weeks, which is 8)

which is
250+600=850

how many more does she need for a car?
she is still missing 2000-850, that is 1150. divide it by 75: it's a little more than 15: so she actually needs to save for 16 weeks after she's been saving for 8, that's a total of 24 weeks.

so in total it will take her 24 weeks (and she will have a little extra).

Marcia drew a plan for a rectangular piece of material that she will use for a blanket. Three of the vertices are (-2.6, -1.5), ( -2.6,3.3), and (2.7, 3.3). What are the coordinates of the fourth vertex?

Answers

Answer:

$(2.7,-1.5)$

Step-by-step explanation:

The points are $A(-2.6,1.5), B(-2.6,3.3), C(2.7,3.3)$

The fourth vertex will can be found by the points $A$ and $C$ .

The angles between the sides of a rectangle are $90^(\circ)$ .

The $x$ coordinate will be the same as $C$ and the $y$ coordinate will be the same as $A$ . The fourth verex is $D$ .

So, the fourth vertex of the rectangular piece will be $(2.7,-1.5)$ .

The value of x for the given line segment LN is 1.

What is a line segment?

A line section that can connect two places is referred to as a segment.

In other words, a line segment is just part of a big line that is straight and going unlimited in both directions.

The line is here! It extends endlessly in both directions and has no beginning or conclusion.

Given,

Line segment LN

LN = 12

Line segment LN has two parts LM and MN

LM = 7x

MN = 2x +4

So,

LN = LM + MN

12 = 7x + 2x +4

9x +4 = 12

9x = 9

x = 1

Hence, The value of x for the given line segment LN is 1.
