12:45Answer:
Part A: 9 hours 45 minutes
Part B: $126.1575
Step-by-step explanation:
Part A,
From 7:45 to 12:15 is 4 hours and 30 minutes
From 12:45 which he clocked back in to 6:00 is 5 hours and 15 minutes.
4 hours and 30 minutes plus 5 hours and 15 minutes = 9 hours and 45 minutes.
Part B, 9 hours and 45 minutes can be represented as 9.45
And since he gets 15.35 "per" hour shows we can multiply.
15.35 x 9.45 = 126.1575
Therefor he earned 126.15.

O g(x) is not a function because f(x) is not one-
to-one.
O g(x) is a function because f(x) is one-to-one.
O g(x) is a function because f(x) is not one-to-

Answer: c
Step-by-step explanation:
The correct statement is that g(x) is a function because f(x) is one-to-one.
What is an inverse function?First to be an inverse function that function needs to one to one function, meaning every different preimage must correspond to a different image.
We can obtain the inverse of a function by switching the variables x and y with their respective positions and solving for y in terms of x.
We know a function f(x) has its inverse g(x) if and only if f(x) is a one-to-one function.
From the given statements the only true statement is, g(x) is a function because f(x) is one-to-one.

A. The relationship between the slope of LN and the O slope of NP cannot be determined, because the triangles are congruent.
B.The slope of LN is greater than the slope of NP This is because the ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is greater for LN than for NP.
C.The slope of LN is less than the slope of NP This is because the ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is less for LN than for NP

Answer:
comparing rates.. use the formula d = r * t where d= distance , r = rate or speed and t = time ofc. :)
Step-by-step explanation:
we know the distance and the time but not the rate.. find that r ....
d/t = r 4/30 = r = 0.13333333333 this is in Km per minute, b/c the 4 is Km and the 30 is in minutes. Units are not to important other than keeping track of what they are.
Now we can answer the question can Marlene run 6 Km in 45 mins. b/c we know her rate , or speed, so at her rate of 0.133333333 Km/min and using that d = r * t formula what is her distance in 45 minutes.. so multiply 45 * 0.133333= 6 so she runs exactly 6 Km in 45 minutes.. so the math answer is yes

Simplify square root -200
Answer:
10 i sqrt 2
Step-by-step explanation:
i indicates that it is an imaginary number. this is because 200 is negative.
The simplified form of the given square root number is 10i√2. Therefore, the correct answer is option D.
The given square root number is √-200.
The square root of a number is the inverse operation of squaring a number. The square of a number is the value that is obtained when we multiply the number by itself, while the square root of a number is obtained by finding a number that when squared gives the original number.
Here, 200 = 2×2×2×5×5
Thus, √-200=√-2×2×2×5×5
=2×5×i√2
= 10i√2
Therefore, the correct answer is option D.

Step-by-step explanation:
Here are recipes for two mixtures of salt and water that taste different. Mixture A: salt (teaspoons) water (cups) 4 5 7 8 3/4 9 11 1/4 Mixture B is defined by the equation y=2.5x , where x is the number of teaspoons of salt and y is the number of cups of water. Respond to the following questions: 1. If you used 10 cups of water, which mixture would use more salt? How much more? Explain or show your reasoning. 2. Which mixture tastes saltier? Explain how you know.
Answer:
1.) Mixture A will use more salt.
Mixture A will require 4 more spoons of salt than mixture B of 10 cups of water is used.
2.) Mixture A
Step-by-step explanation:
Given the daya:
MIXTURE A
___Salt A(teaspoons _____water (Cups)
___4 _____________5
___7 _____________8 3/4
___9 _____________ 11 1/4
Mixture B is defined by the equation'
y = 2.5x ;
x = number of teaspoons of salt ;
y = number of cups of water
Respond to the following questions:
1.) If you used 10 cups of water, which mixture would use more salt? How much more? Explain or show your reasoning.
For mixture B:
If number of cups of water, y = 10
y = 2.5x ; 10 = 2.5x
10/2.5 = x
x = 4 ; 4 teaspoons of salt
Let's write an equation in terms of y and x to represent mixture A.
Mixture A:
5 = k4
k = 5/4
k = 1.25
Equation for mixture A:
y = 1.25x
10 = 1.25x
10/1.25 = x
x = 8 ; 8 teaspoons of salt
Mixture A will use more salt.
Mixture A will require 4 more spoons of salt than mixture B of 10 cups of water is used.
2. Which mixture tastes saltier? Explain how you know.
Mixture A is saltier as it makes use of more teaspoons of salt for the same amount of water.
1. Mixture A will use 4 more teaspoon of salt
2. The mixture that makes use of more teaspoon of salt (4 teaspoon) for the same quantity of water (10 cups) will taste saltier, which is: Mixture A.
Recall:
A proportionate relation is defined by the formula: y = kxk is the constant of proportionality or unit rate between two variables.From the information given:
x = quantity of salt (teaspoons)y = quantity of water (cups)Therefore, k = y/x
Equation for mixture B is given as: y = 2.5x
Using a pair of values from the table for mixture A, let's find the constant of proportionality and the equation that defines Mixture A.
Using (4, 5):
k = y/4 = 5/4 = 1.25Thus, substitute k = 1.25 into y = kxEquation for Mixture A is: y = 1.25x
1. Let's find the mixture that will have more salt if y = 10 (cups of water).
Substitute y = 10 in each equation that defines each mixturesMixture A: y = 1.25x
10 = 1.25x
Divide both sides by 1.258 = x
x = 8
Amount of salt you will have in mixture A is you use 10 cups of water is 8 teaspoonsMixture B: y = 2.5x
10 = 2.5x
Divide both sides by 2.54 = x
x = 4
Amount of salt you will have in mixture A is you use 10 cups of water is 4 teaspoonsThus, Mixture A will use 4 more teaspoon of salt.
2. The mixture that makes use of more teaspoon of salt (4 teaspoon) for the same quantity of water (10 cups) will taste saltier, which is: Mixture A.

At the start of a soccer game, the referee flips a coin to determine which team gets the ball first. The referee making
the calls for your upcoming game has seen the last 5 coin flips come up tails. The team captain plans to call heads
during the coin flip because he says it is long overdue.
Is your friend's reasoning correct?
O Yes, the coin flip is more likely to come up heads in order for the probability of heads to get back to 0.5.
No, it is highly unlikely to get 5 tails in a row by chance alone, so the friend should continue to go with tails. This
referee must be using an unfair coin.
O No, the probability of getting heads or tails is 0.5, regardless of the outcomes of the previous flips.
Yes, after so many tails in a row, the coin is due to show heads.
