A. n = 12
B. n = 15
C. n = 18
D. n = 9

Answers

Answer:D. n = 9

Step-by-step explanation:

n/12 = 3/4 // - 3/4

n/12-3/4 = 0

1/12*n-3/4 = 0 // + 3/4

1/12*n = 3/4 // : 1/12

n = 3/4/1/12

The inequalities h>42 and h<60 represent the height requirements for an amusement park ride, where h represents a person's height in inches.

Write a sentence or draw a sign or that describes these rules as clearly as possible.

Answers

Answer:

42<h<60

H is greater than 42 but less than 60, 42 is less that h and h is less than 60

(I don’t understand what the question is asking for so just correct me if I answered it incorrectly)

According to this inequality, the H must be at least 60 inches taller than 42 inches.

What is linear inequality?

According to the mathematical definition of inequality, neither side is equal. In mathematics, inequality occurs when a non-equal comparison between two expressions or numbers results from the relationship. In this expression, the equal sign "=" can be substituted for any of the inequality symbols greater than (>), less than (<), greater than or equal to (≥), less than or equal to (≤), or not equal to (≠). Mathematically can take many forms, including polynomial inequality, rational inequality, and absolute value inequality.

Given h > 42 and h < 60,

where h is height in inches,

the equation for inequality is,

42 < h < 60

which says that the height of a person should be more than 42 inches and less than 60 inches.

Hence the equation is 42 < h < 60, height should more than 42 inches and less than 60 inches.

You would have to divide 195 by both 15 and 12 to get both hours mowing and hours babysitting.

195 / 15 = 13

195 / 12 = 16 1/4

now if you put the answers in place of b and m you would get (15*13) + (12*16.25) = 195

Answer: 195

Conclusion: Sophia gets over payed

Step-by-step explanation:

One hour of babysitting costs $15 One hour of mowing costs $12

Let the of hours babysitting be x, Let the hours of mowing be y,

$195÷2=$97.5

$195-$49.5 = $145.5 $97.5 - 12 X 4 =$49.5

∴ Total money Sophia got for ∴ Total money Sophia got

baby sitting is $145.5. mowing is $49.5.

Now, Now,

15 X x = $145.5 $12 X y = $49.5

x = [tex]\frac{145.5}{15}[/tex] y = [tex]\frac{49.5}{12}[/tex]

x = 9.7 y = 4.125

∴ Sophie babysitted for ∴ Sophia mowed for 4.125 hours.

9.7 hours.

Note:

You can check if your answer is correct like this:

Multiply 9.7 by $15 ( you will get $145.5 as the answer)

Then, multiply 4.125 by $12 (you will get $49.5 as the answer)

Lastly, add the answers together.($145.5 + $49.5 which will give the answer

as $195)

And boom you got the same answer as written in the question.

It's just a small trick to check if your answer is correct.

I hope this will help you!!!

Okay, to make this easier, I will be counting from 1-8 from the top left to bottom right.

1. Linear

2.Linear

3. Not a function

4. Exponential

5. Exponential

6. Quadratic Function

7. Absolute Value

8. Quadratic Function

For starters, the basic of a function is that for every input there is it's own [nonrepeating] output.

In mathematics, the term linear function refers to two distinct but related notions. We usually describe this as y=mx+b.

Exponential functions are a function of the form {f(x)=ab^{x}} where b is a positive real number, and the argument x occurs as an exponent.

Quadratic function, a quadratic polynomial, a polynomial of degree 2, or simply a quadratic numeral.

An absolute value function contains an algebraic expression within absolute value symbols (the value of a number is its distance from 0 on the number line.) To graph an absolute value function, choose several values of x and find some ordered pairs.

Functions -as stated before have one output for every input. They cannot repeat the same output as the horizontal line would.

Hope this helps mate.

What is the length of the base of a parallelogram if the Area is 125 sq. yds., and the height is 5 yds. ? Just put the answer. Hint: write the formula for area of a parallelogram and substitute what information you know. Use algebra to solve.

Answers

Answer:

25 yd = L

Step-by-step explanation:

The formula for the area of a parallelogram of length L and width W is

A = L * W.

Here we know that A = 125 yd^2, which (from the formula) equals (L)(5 yd).

125 yd^2

Solving for the length, L, we get L = --------------- = 25 yd = L
