0 V6
0 20
20
O 12

Answers

Answer 1

Answer:

0 20

Step-by-step explanation:

x2 + y2 = r2 , and this is the equation of a circle of radius r whose centre is the origin O(0, 0). The equation of a circle of radius r and centre the origin is x2 + y2 = r2 .

Answer 2
Step-by-step explanation:
Equation for circle centered at origin:
x² + y² = r².
r² = (-4)² + (-2)² = 20, r = √20

The amount of money that Maria had in a savings amount at the beginning of 2018 was $2,750. At the beginning of 2019, the same saving account

Answers

Complete question :

The amount of money that Maria had in a savings account at the beginning of 2018 was $2,750. At the beginning of 2019, the same savings account now had $3,201 in it.

By what percent did Maria’s savings increase from 2018 to 2019? Show the work that leads to your answer and do not round.

Answer:

16.4%

Step-by-step explanation:

Given that:

Amount in 2018 = 2750

Amount in 2019 = 3201

Percentage increase in savings :

[(amount saved in 2019 - Amount saved in 2018) / Amount saved in 2018] * 100%

[(3201 - 2750) / 2750] * 100%

= 451 / 2750 * 100%

= 0.164 * 100%

= 16.4%

Kareem received $50 during his birthday. In addition, he saves $10 each week. Which equation can help find w, the number of weeks it will take Kareem to save a total of $200?

Answers

10w+50=200
then to solve-
subtract 50 from both sides so now it’s 10w=150
then divide the 10 from both sides to get w alone
and you should get w=15

Answer: 50+10w=200    w=15

Step-by-step explanation:

So we know that Kareem starts off with $50 and every week he gains an additional $10 so as many weeks it takes to get $150 in addition to the $50 he already has to get $200. so $50+$10w=$200 where w represents the number of weeks it takes until the sum is 200

A bookcase is to have 5 shelves including the top. The height of the bookcase is to be 3 feet more than the width and only 20 feet of lumber is available. Use an equation to determine the width and height of the bookcase?

Answers

Answer:

The width and height is 1.375 and 4.375 respectively

Step-by-step explanation:

The computation of the width and height of the book case is shown below:

Let the width be w

And, the height be h

So, the following equations should be made

5w+3h=20 ......(i)

h = w + 3......(2)

Now

put the value of h in equation (1)

5w + 3(w + 3) = 20

5w + 3w + 9 = 20

8w = 20-9

8w = 11

w = 11 ÷ 8

= 1.375

And, the height would be

= 1.375 + 3

= 4.375

Their data is shown in the table below.

Step-by-step explanation:

The correct graph that represents the given data effectively would be:

Graph C

The given data offers the average ratings of the product and the length of their advertisements in seconds.The third graph most effectively shows the data as it contains provided variables on the appropriate axis i.e. ad length on the x-axis and the average rating on the y-axis. The other graphs fail to represent the explanatory variable and the other variable effectively.

Thus, 'graph C' in the scatter plot format is the correct answer.

x= 23 /7

Step-by-step explanation:

The answer is 10/3=3.333333


Explaination:
(2x-3)/5=(x+1)/6 -> add 3 on both sides
2x /5=(x+4)/6 -> subtract x from both sides
x/5=4/6 -> divide 4 by 6
x/5= 2/3 -> multiply by 5 on both sides
