Tiys earns $7 an hour owing her neighbors lawn.

Part A: create two variables and determine which is dependent and which is independent for this situation.

Part B list three order pairs to show the values of the two variables.

Part C write and equation to represent the relationship between the two variables.

Answers

Answer:

Part A) The independent variable is the hours that Tiya mows her neighbor's lawn, and we can denote that with x. It's the variable that isn't affected by other factors. The dependent variable is the amount of money Tiya earns, which we can denote with y. The dependent variable is the variable that is affected by other factors. The amount of money Tiya makes depends on how many hours she works.

Part B) As stated in part A, x is the hours and y is the money earned. The ordered pairs are in (x, y) form, with x being the hours and y being the money earned. For example, if Tiya worked one hour, x would be 1. As she earns 7 dollars per hour, she would earn 7 dollars (1*7), which is y. Therefore, one ordered pair could be (1, 7). Two hours would give Tiya 14 dollars, so we have another pair of (2, 14). Three hours would give Tiya 21 dollars, so we have (3, 21). We can do that for any numbers.

Part C) With every hour, Tiya earns 7 dollars. In order to find y, which is the amount of money totally earned, we multiply x by 7 (7 dollars per hour). Therefore, y = 7x.

What is the number? pls hlp you'll get 12 points

n = -5

n = 1

n = 5

n = 11

Answers

- 4 × ( n + 8 ) = - 12

Divide both sides by - 4

( - 4 × ( n + 8 ) ) ÷ ( - 4 ) = - 12 ÷ ( - 4 )

Simplification

( n + 8 ) = 3

n + 8 = 3

Subtract both sides - 8

n + 8 - 8 = 3 - 8

n = - 5

2 Charles is saving $5 each week from his allowance. He already saved $15 from the money he earned from mowing his neighbor's lawn. Write the inequality to represent the number of weeks (w) will he need to save in order to save at least $75? (You are not solving this inequality.)​

Answers

Answer:

15 + 5w ≥ 75

Step-by-step explanation:

Let the number of weeks be represented as w.

We are told from the question that:

Charles is saving $5 each week from his allowance. He already saved $15 from the money he earned from mowing his neighbor's lawn.

The word "at least" in mathematics means equal to or greater than and it is represented by the sign ≥

Therefore, our inequality equation is written as:

15 + 5w ≥ 75

Fiona salary is $21000, and she excepts to receive a 3% raise each year; 8 years. The function is y= Her salary after 8 years is $=

Answers

Answer:

her salary after 8 years is $26,602

Step-by-step explanation:

Given that

Fiona salary is $21,000

She received 3% raise each year

We need to find her salary after 8 years

So, here we apply the future value formula

i.e.

= Present value × (1 + rate of interest)^number of years

= $21,000 × (1 + 0.03)^8

= $21,000 × 1.03^8

= $26,602

hence,  her salary after 8 years is $26,602

The ramp on the back of a moving van is 7 ft high and rises at an angle of 28°. How long is the ramp? Round to the nearest foot.

Answers

Answer:

6 feets

Step-by-step explanation:

Height of ramp = 7feets

θ = 28°

Length of ramp = x

Using trigonometric relation :

Sin θ = opposite / hypotenus

Sin 28 = 3 / x

0.4694715 = 3 / x

0.4694715x = 3

x = 3 / 0.4694715

x = 6.39 feets

The length of the ramp = 6 feets

The sum of the arithmetic series is:

893

What are arithmetic progressions?

An arithmetic sequence with a specific number of terms is the sum of all the terms in an arithmetic series.

An arithmetic sequence's first n terms are added together to form (n/2).(a1+an). The arithmetic series formula is what it is known as.

Solution:

Given:

a1 = 11, a2 = 15 and an=83

Step-1:

d= a2 ₋ a1

d= 4

Now, an = a ₊ (n ₋ 1)d

          83 = a ₊ (n ₋ 1)4

          83 = 11 ₊ 4n ₋4

          83 = 7 ₊ 4n

         4n = 83 ₋ 7

          n = 19

Step-2:

Now, Sn = n/2 (a1 ₊ an)

         Sn = 19/2 (11 ₊ 83)

         Sn = 19/2 ₓ 94

         Sn = 893

Hence we get the answer as 893
