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:

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.

x = 5 makes 2x≤ 10 true but not 2x < 10 because "≤" means less than or equal to, which means 2x would be the same as 10, so 10 ÷ 2 = 5, x = 5.

Answer:

Step-by-step explanation:

2x ≤ 10, when x = 5

2(5) ≤ 10

10 ≤ 10 (10 is less than OR equal to 10)

2x < 10, when x = 5

2(5) < 10

10 < 10 (10 is less than 10) - that is false

x = 5 does not makes 2x < 10 true because 10 can't be less than 10.

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.

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

As a result, these systems do not account for the intricacies of the real world. In theory, a command economy promotes fairness and equal distribution of wealth. In reality, its framework cannot account for greed or unchecked power by those in charge. Similarly, a market economy lends itself a winner-take-all attitude. In reality, there is usually a practical need to support members of society who need financial assistance. Because of this, the vast majority of economic systems around the world are mixed economies. The term mixed economy represents a wide spectrum of economic systems.
