STEP-BY-STEP EXPLANATION:
The first thing is to convert the writing into a decimal number and then convert it into a fraction, just like this:
One hundred and twenty four hundredths:
100.24 = 10024/100
Five tenths
0.5 = 5/10
Twenty seven thousandths
0.027 = 27/1000
Fifty two and nine hundredths
52.09 = 5209/100
The freezing point of water is 0 °C. Imanis refrigerator is set at 4°C and her freezer is set at -19°C. which change in temperature would bring imanis refrigerator or her freezer to the same temperature as the freezing point of water?A: +23°CB: +15°CC: -19°CD: -4°C
The freezing point of water is 0 °C
The tempreature of Imanis refrigerator = 4degree C
and the freezer is -19 degreeC
So, the net tenpreature of refrigerator is 4+(-19)
The net tempreature = (-15) degreeC

Find the area of the circle if the square has an area of 900 in.² to give your answer in terms of
Diameter of circle = length of each side of the square
The formula for calculating the area of a square is
Area = l^2
where l is the length of each side
From the information given,
Area = 900
900 = l^2
l = √900
l = 30
diameter = 30
radius = diameter/2 = 30/2
radius = 15
The formula for calculating the area of a circle is
Area = πr^2 = π * 15^2
Area of circle = 225π in^2

STEP-BY-STEP EXPLANATION:
[tex]undefined[/tex]A teacher asks students to determine the accuracy of this statement.A reflection over the x-axis and then over the y-axis results in the same transformation as a 180° rotation about the originof the original figure.Kwame's explanation of the accuracy of the statement is shown below.Step 1: Choose the vertices of a pre-image: (1, 2), (1, 4), (2, 3).Step 2: Reflect the pre-image over the x-axis: (1, -2), (1, -4), (2, -3).Step 3: Reflect the figure from step 2 over the y-axis: (-1,2), (-1, 4), (-2, 3).Step 4: Rotate the pre-image 180°:(-1, -2), (-1,-4), (-2, -3).Step 5: Compare the reflected figure to the rotated figure. The vertices are not located in the same place, therefore thestatement made by the teacher is inaccurate.Which best explains Kwame's solution?
(Reminder: To find the reflection over the x-axis, we just need to switch the signal of the y-coordinate of the points.
To find the reflection over the y-axis, we just need to switch the signal of the x-coordinate of the points)
Kwame's solution has a mistake in step 3:
The figure from step 2 is:
(1, -2), (1, -4), (2, -3).
Then, when reflecting these points over the y-axis, the result is:
(-1, -2), (-1, -4), (-2, -3)
At this point Kwame wrote (-1,2), (-1, 4), (-2, 3), which is incorrect.
Step 4 is correct, then when comparing the images in step 5, the vertices will be located in the same place, therefore the statement made by the teacher is accurate.

An ordered pair refers to a pair of two numbers or variables written inside the bracket and separated by comma.
To find an ordered pair of a equation we just need to find the values of x and y which will satisfy the given equation.
Here given equation is 4x-y=5
So we will put x=0 and y=-5
⇒ 4(0)-(-5)=5
Therefore (0.-5) satisfy given equation.
Hence (0.-5) is an ordered pair of 4x-y=5.
Note:- There are many ordered pairs that satisfy the given equation.

In a survey, 315people said they drivetheir car to work. Thisrepresents 90% of thepeople surveyed.How many peoplewere surveyed?
We know that 90% is equivalent to 315 people and we want to know how many people are equivalent to 100%. So, using the rule of three, we get:
90% ------------------- 315
100% ------------------ X

Ten yards of a particular kind of wire cost $15.30 . What is the cost of the wire per foot?
Given:
Length of wire = 10 yards
Total cost of wire = $15.30
To be able to determine the cost of wire per foot, let's first convert the unit of measure of the wire's length from yards to feet.
Recall: 1 yard = 3 feet
Step 1: Convert the measure of the wire length from yards to feet.
[tex]\text{ 10 (yards) x }\frac{\text{ 3 feet}}{\text{ 1 (yard)}}\text{ = }\frac{\text{10 x 3}}{\text{ 1}}\text{ feet}[/tex][tex]\text{ = 30 feet}[/tex]Therefore, 10 yards is equivalent to 30 feet.
Step 2: Divide the total cost by the total length of wire in feet.
[tex]\text{ Cost of wire per foot = }\frac{\text{ Total cost of wire}}{\text{ Total length of wire}}[/tex][tex]\text{ = }\frac{\text{ \$15.30}}{\text{ 30 feet}}[/tex][tex]=\text{ \$0.51 per foot}[/tex]Therefore, the cost of the wire per foot is $0.51
What is the meaning of the slope of the equation in this context?
ANSWER
It is the cost for printing each DVD
EXPLANATION
We want to find out what the slope of the equation represents.
The equation given is a linear equation. The slope of a linear equation represents the rate at which the dependent variable changes with respect to the independent variable.
The independent variable is the number of DVDs while the dependent variable is the cost to make the DVDs.
Hence, the slope represents the cost of the DVDs per DVD. In other words, it represents the cost for printing each DVD.

Write two fractions where the denominator of one is a multiple of the denominator of other
The two fractions are; 1/3 and 1/9.
What is a fraction?A fraction has two parts: Numerator and Denominator.
It is in the form of a Numerator / Denominator. A fraction is a numerator divided by the denominator.
We need to write two fractions where the denominator of one is a multiple of the denominator of the other.
Let's consider the first fraction as;
1/3
Then other fraction must be multiple of the denominator of the other.
So, it can be 1/9
We can see that "the denominator of one is a multiple of the denominator of other".
Thus the two fractions are; 1/3 and 1/9.
