Answer:
Option C is correct.
The inequalities can be written as one statement as : h<7 or h>9
Step-by-step explanation:
Let h be the working hours
Antonio can drive home after working less than 7 hours.
Less than symbol represented by ('<')
then, we have h<7
Antonio after working more than 9 hours.
More than symbol represented by ('>').
then, we have h>9
Since, we use inequalities when there is a range of possible answers for a given situation
Now, as per the given statement,
the inequalities can be written as one statement as; h<7 or h>9
Find the circumference of a circle whose area is 24pi ft^2
Answer:
30.76 [tex]ft^{2}[/tex]
Step-by-step explanation:
To calculate the circumference of a circle you just have to multiply the diameter by pi.
C= D*[tex]\pi[/tex]
And in order to calculate the value of the diameter you have to clear the formula for the area.
A= [tex]r^{2} *\pi[/tex]
r=[tex]\sqrt{\frac{24 \pi }{\pi } }[/tex]
r=[tex]\sqrt{24}[/tex]
r=4,89
Once we get the radius, we only have to calculate the diameter:
D=2r=9,79
now we just calculate the circumference:
C=D*[tex]\pi[/tex]= (9.79)(3.14)= 30.76
A circle is increased to have a circumference that is 4 times larger than the original. Which of the following options best describes the change in the radius of the original circle?

Melissa and Emily are playing at the pool.They have three different measuring jars for; liters, cups, and pints. They find that 7 cups of water and 3 liters of water filled 9.8 pints. Later, they find that if they start with 5 liters of water and remove 9 cups of water, they end up with 6 pints of water. Model the given two situations as a system of linear equations. Based on your equations, determine the relationship between;
●cups and liters,
●cups and pints,
●and pints and liters.
Show all your work and submit your work along with the resulting relationships.
Here's work you can copy and paste:
7 cups + 3 liters = 9.8 pints
7c+3l=9.8p
5 liters - 9 cups = 6 pints
5l+9c=6p
Cups and Liters
7c+3l=9.8p
p= 7c+3l/9.8 (put in equation 2)
5l-9c= 7c+3l/9.8
49l-88.2c=7c+3l
49l-3l=7c-88.2c
46l=45.2c
1Liter = 2.1 Cups
Cups and Pints
7c+3l=9.8p
3l=9.8p-7c
l=9.8p-7c/3 (put in equation 2)
5(9.8p-7c/3)-9c=6p
(49p-35c/3)-9c=6p
49/3p-35/3c-9c=6p
49/3p-6p=35/3c+9c
31/3p=62/3c
1 Pint = 2 Cups
Pints and Liters
7c=9.8p-3l
c=9.8p-3l/7 (put in equation 2)
5l-9(9.8p-3l/7)=6p
5l-63/5p+27/7l=6p
5l+27/7l=6p+63/5p
62/7l=93/5p
1 Liter = 2.1 Pints

The graph of f(x) = (0.5)x is replaced by the graph of g(x) = (0.5)x − k. If g(x) is obtained by shifting f(x) down by 2 units, the value of k is ________. Numerical Answers Expected!
Answer: The value of k is 2.
Step-by-step explanation:
Given : The graph of [tex]f(x)=(0.5)x[/tex] is replaced by the graph of [tex]g(x)=0.5)x-k.[/tex]
If g(x) is obtained by shifting f(x) down by 2 units, then [tex]g(x)=(0.5)-2[/tex]
[since f(x)shifted down down by 2 , so only the value of dependent variable effect]
When we compare both functions of g(x), we found that k=2.
Hence, the value of k is 2.
The value of [tex]k[/tex] is 2.
The following information should be considered:
when [tex]g(x)[/tex] is obtained by shifting f(x) fall by 2 units so [tex]g(x) = (0.5) - 2.[/tex]Since [tex]f(x)[/tex] shifted down by 2 so there is the effect on the dependent variable. Now at the time of comparing both functions of g(x) the k should be 2.Learn more: brainly.com/question/17429689

classify the following triangle . check all that apply
Answer:
Option (a) and (d) is correct.
The given triangle is obtuse and isosceles.
Step-by-step explanation:
Given : A triangle with measure of one angle is 120° and two legs of the triangle are given equal in length.
We will have to choose the correct classification for the given triangle.
For a triangle if the measure of one the angles is
1) less than 90 then it is acute triangle ,
2) equal to 90 then right triangle
3) greater to 90 then obtuse triangle
Since the measure of one angle of the triangle is 120° > 90° Thus, the given triangle is obtuse.
For a triangle if all the three sides are equal then it is equilateral triangle, if two sides are equal then it is isosceles and if no side is equal then it is scalene.
Since, for the given triangle, the two legs of the triangle are given equal in length so it is an isosceles triangle.
Thus, the given triangle is obtuse and isosceles.

Which best describes the range of the function f(x) = 2(1/4) after it has been reflected over the y-axis? all real numbers all real numbers less than 0 all real numbers greater than 0 all real numbers less than or equal to 0
Answer:
All real numbers greater than 0.
Step-by-step explanation:
We have the function, [tex]f(x) = 2(\frac{1}{4})^{x}[/tex].
'Reflection over y-axis means to flip the graph over y-axis', which changes the function by f(x) becomes f(-x).
So, after reflection, the given function transforms into,
[tex]g(x)=f(-x)[/tex]
i.e. [tex]g(x)=2(\frac{1}{4})^{-x}[/tex]
According to the graph of the function g(x), we see that,
Range of [tex]g(x)=2(\frac{1}{4})^{-x}[/tex] is the 'Set of all real non-negative numbers' i.e. {x | x > 0} i.e. [tex](0,\infty)[/tex]

A dogs weight increased by 50% in 3 years . By the end of the 3years , the dog weighed 45 pounds . How much did the dog weigh 3 years ago
Final answer:
To calculate the dog's weight from three years ago, we take the current weight and divide it by 1.50 since the weight increased by 50%. The equation 1.50 * x = 45 pounds results in x = 30 pounds, indicating the dog weighed 30 pounds three years ago.
Explanation:
The question concerns the original weight of a dog whose weight increased by 50% over a period of three years, bringing its weight to 45 pounds at the end of that period. To determine the dog's weight from three years ago, we use the following steps:
Understand that a 50% increase implies that the final weight is 150% of the original weight (100% + 50%).
Represent the original weight as 'x'.
Set up the equation: 1.50 * x = 45 pounds.
Divide both sides by 1.50 to solve for 'x': x = 45 / 1.50.
Calculate 'x' to find that 'x' equals 30 pounds.
Therefore, the dog weighed 30 pounds three years ago.

Part A:(This table is a three by three table, with the first top two sections being liked apple juice and didn't like apple juice, and the first left two sections being liked orange juice and didn't like orange juice. The end sections are totals.)
Answer:
Part A: A = 8
B = 20
C = 28
D = 35
E = 37
F = 72
G = 43
H = 57
I = 200
Part B: 18.5%
Part C:
D = People who do not like Orange Juice
B = People who do not like Apple Juice
I use the values of B and D because these are the values that represent dislike for that juice, and also because adding them together creates a value for not liking either juice.
D = 35
B = 20
So there is a greater dislike for Orange Juice.
