It costs $100 to join a fitness center, plus a monthly fee. You spent $700 last year at the fitness center. How much was the monthly fee? Write and solve an algebraic equation to determine the monthly fee.

Answers

Answer:

Monthly fee is $50

Step-by-step explanation:

100 + 12x = 700

12x = 600

x = 50

100 being the initial fee, 12x being the monthly fee (as there is 12 months in a year).

monthly fee is 50. so we started with 700 a year but since it cost 100 to join we minus it from 700 so it will be 600. and since there are 12 months in a year we divide 600 by 12 and that equals 50.

Answer:

The answer is b.

Step-by-step explanation:

if you look up what a ray is, it will look like the description b has.

D) A line is a set of points that extends infinitely in both directions.

Answer choice A is incorrect because only two points are required to determine a line.

Answer choice B is incorrect because a ray includes one endpoint and one arrowhead that extends infinitely.

Answer choice C is incorrect in reference to the same explanation as answer choice B.

Therefore, answer choice D would be the correct and true statement.

What is the absolute deviation of 16 in this data set?{19, 16, 4, 9, 7}2578

Answers

The absolute deviation of 16 in the given data set, {19, 16, 4, 9, 7}, is: B. 5.

What is Absolute Deviation?

The absolute deviation of a data point in a data set, is the distance of that data point from the mean of the data set.

Find the mean of the data set:

Mean = (19 + 16 + 4 + 9 + 7)/5 = 55/5

Mean = 11

16 - 11 = 5

Therefore, the absolute deviation of 16 is: B. 5.

Answers

Answer:

$43 million

Step-by-step explanation:

Step 1. Turn the sentence into an equation (total = T)

15.4 million = 0.36 (T)

Step 2. Solve for T

15,400,000 / 0.36 = T

42,777,777.78 = T

$42.8 million ≈ $43 million (rounded)

The final answer rounded to the nearest million is $43 million. This makes sense since $15.4 was only 36% of this total. Checking our math, 36% of $43 million is $15.4 million!

Hope this helps :)

Its should be 43 million

Answer:

N = 85

Step-by-step explanation:

(236 + 542)+N = 863

778 + N = 863

N = 863 - 778

N = 85

Answer:

N=85

Step-by-step explanation:

(236 + 542) + N = 863

Go in order of PEMDAS (Parantheses, Exponents, Multiplication, Division, Addition, Subtraction)

236 + 542= 778

now we have

778+N = 863

(778 plus a number equals 863)

to find the number (N) we can subtract 778 from 863.

863-778=85

so,

N = 85

Roger gets $40 per day as wages and $4.50 as commission for every pair of shoes he sells in a day. His daily earnings goal is $112.

Write an equation to determine how many pairs of shoes, p, Roger must sell in a day to meet his daily earnings goal.

Find the number of pairs of shoes he must sell to meet his daily earnings goal.

Answers

Step-by-step explanation:

Equation to determine how many pairs of shoes :- S = 40 + 4.5x

Where,

S is Earnings

x is Shoe

⇒ 112 = 40 + 4.5x

⇒ 40 + 4.5x = 112

⇒ 4.5x = 112 - 40

⇒ 4.5x = 72

⇒ 4.5x/4.5 = 72/4.5

⇒ x = 16

[tex]\therefore [/tex] Roger must sell 16 shoes per day to meet his daily earning goal

For each ordered pair,solve the percent problems to find the corridinates (x% of 31 is 3.317,4.407 is 39% of y)

Answers

Answer:

x=10.7, y=11300

Step-by-step explanation:

x%of 31 = 3.317

x/100×31=3.317

31x/100=3.317

31x= 3.317×100

x= 3.317 ×100/31

x =10.7

4407= 39% of y

4407= 39/100 × y

4407 =39y/100

4407×100=39y

4407 × 100/39=y

11300=y
