Step-by-step explanation:

A new homeowner needs to determine the length of his rectangular backyard before he goes to the store for

fencing. He knows that the area of the yard is 51 square meters and that the width is 5.2 meters longer

than the length. Which equation could be solved to determine the dimensions of the backyard, where the length

is / and the width is w?

0=w2+5.2w -51

o

0=12+5.21-51

4w + 10.4 = 51

о

41 +10.4 = 51

Answers

Answer:

The equation used to solved to determine the dimensions of the backyard is 51 = 4w - 10.4

Step-by-step explanation:

As given,

The backward is rectangular in shape

Also , we know that

Area of rectangle = 2 ( Length + Breadth )

Also, given,

Breadth of the backyard = 5.2 + Length of the backyard

Let

length of the backyard = l

Breadth of the backyard = w

∴ we get

w = 5.2 + l

⇒l = w - 5.2

and

Area = 2 ( l + w)

⇒51 = 2( w - 5.2 + w)

⇒51 = 2 ( 2w - 5.2)

⇒51 = 4w - 10.4

So, the equation used to solved to determine the dimensions of the backyard is 51 = 4w - 10.4

By solving we get

4w = 51 + 10.4

⇒4w = 61.4

⇒w = [tex]\frac{61.4}{4}[/tex] = 15.35

⇒ w = 15.35

⇒ l = w - 5.2 = 15.35 - 5.2 = 10.15

⇒l = 10.15

So the dimensions of the backyard = l × b = 10.15 m × 15.35 m

Right now, Molly is twice as old as Nancy. Zander is 6 years younger than Molly.

Which expression represents Molly’s current age in terms of Nancy’s?


Which expression represents Molly’s current age in terms of Zander’s?


Nancy is currently 10 years old, and Zander is 14. How old is Molly?

Answers

1) let molly be y
And let Nancy be x
Since molly is twice as Nancy
So equation is 2x=y
(Twice Nancy age is equal to Molly’s age)

2)let molly be y
Let zanders age be z
Since zander is 6 yrs younger than molly
So 6yrs added to zanders age equals Molly’s age
Eq: z+6=y

3) ) molly’S age =y,Nancy age =x
Since molly is twice as Nancy
So 2x=y. (Nancy is 10 .....given )
2*10 = 20
Or
molly =y
zanders =z
Since zander is 6 yrs younger than molly
Eq: z+6=y ( zandra is 14 ...given )
14+6=20

Over what interval is the function in this graph constant? A. 65*10 B, 1 sxs6 C. -4 sxs1 D. -10 5-4 ​

Answers

Given:

The graph of a function.

To find:

The interval at which the graph of the function is a constant.

Solution:

From the given graph it is clear that the graph is a horizontal line and parallel to the x-axis over the interval [tex]1\leq x\leq 6[/tex].

Over the interval [tex]1\leq x\leq 6[/tex], the value of the function is constant, i.e., y=7.

It means the graph of the function is constant over the interval [1,6].

Therefore, the correct option is B.

1) Walter opened a bank account with $0. He deposits $200 in the bank
each month. Write an expression that represents how much money
Walter has deposited after some number of months (m). Which
student below is correct? What mistake do the other students make?
Student A
200*10
Student B
2200
Student C
200m
Student D
m = 200

Answers

Answer:

Student C is correct.

Students A and B do not account for the variable in the equation. Student A assumes that it has already been 10 months when it has not been stated in the question. Student B has come to the conclusion that it has been 11 months. Neither have an equation to show for it. Student D is incorrect because the variable "m" equals the number of months, and the number of months would not equal the amount of money Walter would be receiving in total. Student C is correct because the variable "m", or months, is being multiplied by 200, or the amount of money.

For example, if 5 months were to pass, then you would receive 1000 dollars, because 5×200 is 1000. This would hold up, as in the original problem, you receive 200 dollars per month. another example is if you replace "m" with 0, then it will show that in 0 months, you will have 0 dollars, and it is stated at the beginning of the problem that Walter's bank account starts at $0.

Answers

Answer:

x is less than or equal to 0

Step-by-step explanation:

- you need to multiply both sides of the inequality by 5/2

- then you reduce the numbers with the greatest common factor 5

- then you reduce the numbers with the greatest common factor 2

- any expression multiplied by 0 equals 0

- so you get x is less than or equal to 0

A savings account earns 4.5% simple interest per year. If $650 is deposited and no withdrawals are made during one year, how much interest will be earned after one year?

Answers

679.25 is the answer

Answer:

$29.25

Step-by-step explanation:

The formula for amount of interest is the P*R*T. Because the principal is $650 dollars, and the rate is 4.5% for 1 year, the formula so far is 650*0.045*T. The interest is per annum or annual, so the time has to be in terms of years, which in this case is 1 year. This would give you 650*0.045. The answer for that is simply $29.25.
