The tables show the books read by two different students. Explain how to determine which student read faster.
The first student read faster than the second student.
Step-by-step explanation:
Step 1:
To determine how long each student takes to read a book, we divide the time taken to read by the number of books read in that period.
Time taken to read a book = [tex]\frac{time taken to read}{number of books read in that period}[/tex].
In the given table, the second column values are times taken to read and the first column represents the number of books read in that period.
Step 2:
For the first student, the time taken is calculated.
The first student's time taken to read a book = [tex]\frac{30}{3}[/tex] = [tex]\frac{50}{5}=\frac{70}{7}[/tex] = 10 minutes to read a book.
Step 3:
Similarly, the time taken to read a book is calculated for the second student.
The first student's time taken to read a book = [tex]\frac{24}{2}=\frac{48}{4}=\frac{72}{6}[/tex] = 12 minutes to read a book.
Step 4:
Now we compare the times taken. The first student read a book in 10 minutes while the second student took 12 minutes for a book. So the first student read faster.

Two figures are congruent. Are the areas of the two figures
the same? the perimeters? Explain your reasoning.
Both area and perimeter are the same. They have the same shape and dimensions.
This is because congruency means that the two figures are identical, one is the clone of the other.
Two congruent figures have identical shape and size, meaning their perimeters and areas are both equal.
If two figures are congruent, this means that they are identical in shape and size. Congruent figures are essentially the same figure superimposed from one location to another. According to the definition of congruent figures, corresponding angles and sides are equal. Therefore, since the dimensions of congruent figures are the same, the perimeters of the figures must also be the same. This is because perimeter is a linear measure, which is the sum of the lengths of the sides of a figure.
Similarly, since congruent figures are identical in size, their areas must also be the same. Area is a measure of the extent of a 2-dimensional surface enclosed by a figure. Since the figures are congruent, they cover the same amount of 2-dimensional space, thus their areas are equal. Theorems 9 and 12 mentioned in the reference material confirm these properties.

The diagram below shows scalene triangle JKL.
Which is true about the diagram? Select two options.
Measure of angle J K H + measure of angle J K L = 180 degrees
Measure of angle J K L + measure of angle J L K + measure of angle K J L = 180 degrees
Measure of angle J K H = measure of angle J L K
Measure of angle J K L + measure of angle J L K = 90 degrees
Measure of angle K J L = measure of angle K L J
The correct statement about the diagram is,
⇒ Measure of angle JKH + measure of angle JKL = 180 degrees
⇒ Measure of angle JKL + measure of angle JLK + measure of angle KJL = 180 degrees
What is mean by Angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
Given that;
The diagram is shown.
Now, By definition of linear pair of angles, we get;
⇒ m ∠JKH + m ∠JKL = 180°
And, The sum of angles in triangle is 180°
Hence, We get;
⇒ m ∠ JKL + m ∠ JLK + m ∠ KJL = 180 degrees
Thus, The correct statement about the diagram is,
⇒ Measure of angle JKH + measure of angle JKL = 180 degrees
⇒ Measure of angle JKL + measure of angle JLK + measure of angle KJL = 180 degrees

I need help for #9 please help I got math class in 30 minutes :))!! Thank u
In questions it's given that ∠B = 85°, which is an error and correct answer is ∠B = 95°.
Step-by-step explanation:
We know that sum of alternate angles in a parallelogram is 180°. Using this property, we will solve the question! We have a parallelogram inscribed in a circle with measure of angles as ∠A=100° and ∠D=85°. Now, according to property : ∠A + ∠C = 180° and ∠D + ∠B = 180°.
Let's consider for ∠D + ∠B = 180°:
⇒ 85° + ∠B = 180°
⇒∠B = 180° - 85°
⇒∠B = 95°
Also, for ∠A + ∠C = 180°:
⇒ 100° + ∠C = 180°
⇒∠C = 180° - 100°
⇒∠C = 80°
In questions it's given that ∠B = 85°, which is an error and correct answer is ∠B = 95°.
Consider the point A = (1,3) and the line B, given by the equation y = 2x-2. Write an equation in slope intercept form of the line passing through point A and parallel to line B.
Please help!
The equation of the line in slope intercept form is [tex]y=2x+1[/tex]
Explanation:
The point A is [tex](1,3)[/tex]
The equation of line for B is given by [tex]y=2x-2[/tex]
We need to determine the equation of line in slope intercept form passing through the point A and parallel to line B.
Since, the lines of equation are parallel, their slopes are same.
Thus, the slope is [tex]m=2[/tex]
Now, let us substitute the point [tex]A(1,3)[/tex] and slope [tex]m=2[/tex] in the slope - point formula, we have,
[tex]y-y_{1}=m\left(x-x_{1}\right)[/tex]

Find the value of c.
Answer: c=35
Step-by-step explanation:
to find the slope, you do y2-y1/x2-x1. So you will set up your equation like this:
25-c/21-15 = -5/3
this slope has been simplified by dividing by 2, because 21-15=6 and they simplified it to 3. So the original answer for 25-c was -10. So this means that c=35.

What is 34.02 estimated?
Answer: 34
Step-by-step explanation:
Final answer:
To estimate 34.02, we would round it to the nearest whole number which is 34.
Explanation:
When asked to estimate 34.02, we look for a number that is close in value but simpler or more convenient to use.
Estimation often involves rounding to a certain place value depending on the level of precision required.
In this case, we can round to the nearest whole number. 34.02 is very close to 34, so the estimated value is 34.
This is based on traditional rounding rules where if the digit right after the place you are rounding to is less than 5, you keep the digit the same. If it is 5 or more, you round up. Since the decimal part .02 is less than .05, we do not round up.

A container has a volume of 860 cm?.
Find its capacity.
Answer:
0.86liters
Step-by-step explanation:
860cm³=0.86dm³=0.86liters
The capacity of the container is 860 cm³.
To find the capacity of the container, we need to understand that the volume and the capacity are essentially the same thing when referring to containers.
The volume of a container is the amount of space it occupies, and the capacity is the amount of fluid or substance it can hold. Since the volume is already given in cubic centimetres (cm³), which is a unit of volume, it directly translates to the capacity of the container.
Therefore, without the need for any conversion or further calculation, we can state that the capacity of the container is 860 cm³. If one were to express this capacity in litres, knowing that 1 liter is equivalent to 1000 cm³, we could perform a conversion:
[tex]\[ \text{Capacity in liters} = \frac{\text{Capacity in cm}^3}{1000} \][/tex]
[tex]\[ \text{Capacity in liters} = \frac{860}{1000} \][/tex]
[tex]\[ \text{Capacity in liters} = 0.86 \][/tex]
So, the capacity of the container is 0.86 litres, which is equivalent to 860 cm³.

Carrie started at the southeast corner of Franklin Park, walked north 240 yards, turned and walked west 80 yards, and then turned and walked diagonally back to where she started. What is the area of the triangle enclosed by path she walked?
The area is 9,600 square yards.
Carrie's walk forms a right-angled triangle, with the two legs being her north and west paths, and the hypotenuse being the diagonal path back to the start. To find the area of the triangle, we can apply the formula for the area of a right-angled triangle, which is (1/2) * base * height. In this case, the base is her westward walk (80 yards), and the height is her northward walk (240 yards).
Using the formula, the area equals: (1/2) * 80 yards * 240 yards, yielding an area of 9,600 square yards.

A retail store offers all television sets at 80% or 80/100 of their original price if the customer buys a store membership for 100.00. If the p is the price of a television set. How much will a 1500.00 television cost
Answer: $1875
Step-by-step explanation:
If 80% of original price= $1500
Let the remaining 20% be x
Write as:
80/100 = $1500
20/100 = x
Cross multiply
0.8x = 1500 x 0.2
0.8x= 300
Divide both sides by 0.8
x = 300/0.8
x = 375
Therefore, 80% = 1500; 20% = 375
Price of $1500 TV without membership = $1,500 + $375
=$1,875
Answer:
