Answer:
1. 676 2. 10,000 3. 2,500 4. 1,681
Step-by-step explanation:
1. Using the Pythagorean Theorem (a sqaured + b sqaured = c sqaured) you do 10 sqaured plus 24 squared which equals 676.
2. By using the same Theorem, you do 60 sqaured plus 80 sqaured which equals 10,000.
3.By using the same Theorem, you do 30 sqaured plus 40 sqaured which equals 2,500
4.By using the same Theorem, you do 40 sqaured plus 9 sqaured which equals 1,681.
Vikram drinks 6/10 of a liter of water after gym class and 33/100 hours of a liter of juice with
his lunch. Vikram says he drank a total of 39/100
of a liter.
Use the drop-down menus to explain why Vikram is not correct.
The Vikram is not correct as he said that he drank a total of 39/100
of a liter in gym class and in his lunch, but he drank a total of 39/100 of a liter.
What is the fraction number?A fraction number is the number which is a part of a whole number. It is written with a numerator and denominator. Fraction number are written as,
[tex]\dfrac{a}{b}[/tex]
Here (a) is the numerator and (b) is the denominator.
Vikram drinks 6/10 of a liter of water after gym class and 33/100 hours of a liter of juice with his lunch.
Thus, the total amount he drank is,
[tex]n=\dfrac{6}{10}+\dfrac{33}{100}\\[/tex]
Take the LCM 100, to solve it further,
[tex]n=\dfrac{60+33}{100}\\n=\dfrac{99}{100}\\[/tex]
Now, Vikram says he drank a total of 39/100 of a liter, which is an incorrect claim.
Thus, the Vikram is not correct as he said that he drank a total of 39/100
of a liter in gym class and in his lunch, but he drank a total of 39/100 of a liter.

4(x +t) = M
Answer:
x = (M-4t)/4
Step-by-step explanation:
First we expand the brackets:
4(x+t) =M
4x +4t = M
Subtract 4t from both sides:
4x +4t -4t = M -4t
Simplify:
4x = M -4t
Divide both sides by 4 :
4x÷4 = (M-4t)/4 = (M-4t)÷4
x = (M-4t)/4

Which expression is equivalent to log18 – log(p 2)?
The expression which is equivalent to the provided logarithmic equation log18 – log(p +2) is log[18/(p+2)].
What is the equivalent expression?Equivalent expressions are the expression whose result is equal to the original expression, but the way of representation is different.
The given logarithmic expression is,
[tex]\log18 -\log(p+ 2)[/tex]
Let the expression which is equivalent to above expression is f(p). Thus,
[tex]f(p)=\log18 -\log(p+ 2)[/tex]
With the help of Quotient Rule of logarithmic, the above expression can be written as,
[tex]f(p)=\log18 -\log(p+ 2)\\f(p)=\log\left(\dfrac{18}{p+2}\right)[/tex]
Thus, the expression which is equivalent to the provided logarithmic equation log18 – log(p +2) is log[18/(p+2)].

Mr. Schultz is randomly distributing 15 rulers with centimeter markings and 10 rulers without centimeter markings to his class. What is the probability that the first ruler he hands out will have centimeter markings and the second one does not have the markings?
The probability that the first ruler he hands out will have centimeter markings and the second one does not have the markings is 9/40.
Probability of distributing the rulers
The probability of distributing the rulers is calculated as follows;
Total outcome = 15 rulers with centimeter markings + 10 rulers without centimeter markings
Total outcome = 25
The probability that the first ruler he hands out will have centimeter markings and the second one does not have the markings;
P = (R with M) and (R without M)
P = (15/25) x (9/24)
P = (3/5) x (3/8)
P = 9/40
Thus, the probability that the first ruler he hands out will have centimeter markings and the second one does not have the markings is 9/40.

Consider two events, P and Q. The probability of event P occurring is 16. The probability of event Q occurring is 23. Which statement is true?
The event "P and Q" is a compound event in the probability, and the true statement about the probability is P(P and Q) = 1/9
How to determine the true statement?The probabilities are given as:
P(P) = 1/6
P(Q) = 2/3
The probability of the event P and Q is calculated using:
P(P and Q) = P(P) * P(Q)
This gives
P(P and Q) = 1/6 * 2/3
Evaluate the product
P(P and Q) = 1/9
Hence, the true statement about the probability is P(P and Q) = 1/9

An above ground pool is shaped like a cylinder. It is 5.5 feet tall and has a diameter of 20 feet. If the pool is filled to 5 feet, what is the volume of the water? If the pool is filled to the top, what is the volume of the water?
First, we must know the formula for solving the volume of a cylinder, which is [tex]V = \pi r^2 h[/tex]. Since the water is only being filled to 5 feet, we do not care about the 0.5 feet of the height.
Using the formula, we need to plug-in the numbers for the radius (20 divided by 2 is 10) and height. Doing this, the equation should now look like this: [tex]V = 3.14 * 10^2 * 5[/tex]. When solving, the volume of the water is 1570 feet cubed.
Answer:
1570.796 feet cubed
Step-by-step explanation:
First you find the surface area of the base of the cylinder which should look like this:
(10^2)(π)
Next you multiply that by the height (5 feet) because 3d shapes are bases stacked on each other which should look like this:
314.1592654(5)
After that arithmetic you will get 1570.796 or 1570.8 rounded as your answer!
Find the measure of angle CED in the figure below. Enter only the number.
Answer:
∠CED = 58°
Step-by-step explanation:
Clearly, we can see that ∠AED and ∠CED are a linear pair. Therefore:
∠AED + ∠CED = 180°Definition of Linear pair: A linear pair is two angles that form a 180 angle.
We are given that:
∠AED = 122°Therefore, when we substitute the measure of ∠AED, we get;
122° + ∠CED = 180°This problem is now an algebraic problem. Simply isolate ∠CED on one side of the equation to determine the measure of ∠CED. This can be done by subtracting 122 both sides of the equation.
∠CED = 180° - 122°∠CED = 58°Therefore, the measure of ∠CED is 58°.
The measure of angle CED is 58° adjacent to the angle AED.
What is a linear pair of angles?A pair of linear angles are adjacent to each other whose sum is 180°.
Given, a measure of the angle AED is 122°
We know the measure of linear pair of angles is 180°.
∴ m∠AED + m∠CED = 180°.
122° + m∠CED = 180°.
m∠CED = 180° - 122°.
m∠CED = 58°.
