Step-by-step explanation:
Chelsea is making a kite in the shape of a triangle. To determine if the triangle is a right triangle, Chelsea completed the following steps.
Step 1:
Find the side lengths of the triangle: 30 inches, 24 inches, 18 inches.
Step 2:
Substitute the values into the Pythagorean theorem: 18 squared + 24 squared = 30 squared.
Step 3:
Combine like terms: (18 + 24) squared = 30 squared.
Step 4:
Evaluate each side: 1764 not-equals 900.
Chelsea says the triangle is not a right triangle. Which best describes the accuracy of her explanation?
The triangle is actually a right triangle. In step 2, Chelsea incorrectly substituted the values into the Pythagorean theorem.
The triangle is not a right triangle, but in step 2 Chelsea incorrectly substituted the values into the Pythagorean theorem.
The triangle is actually a right triangle. In step 3, Chelsea incorrectly rewrote the expression on the left side of the equation.
The triangle is not a right triangle, but in step 3, Chelsea incorrectly rewrote the expression on the left side of the equation.

Find the height of a cone with a diameter of 12 m and whose volume is 133 m.
A. 2 m
B. 9 m
C. 3 m
D. 1 m
Answers
Answer:
D
Step-by-step explanation:
Here, we want to get the height of the cone
radius = diameter/2
r = 12/2 = 6 m
To get this, we use the formula for the volume
V = 1/3 * pi * r^2 * h
133 = 1/3 * 3.142 * 22/7 *6^2 * h
h = 1.12 m
the pet store has 8790 clownfish. they keep 6 fish in one tank . how many tanks do they have?

PLS HELP- Richard and Teo have a combined age of 33. Richard is 15 years older than twice Teo's age. How old are Richard and Teo?
Answers
Answer:
Teo= 9
Richard= 24
Step-by-step explanation:
x= Richard
y= Teo
33-15= 18
18÷2= 9
15+9=24
Teo is 6 years old and Richard is 27 years old.
What is the equation?The equation is defined as a mathematical statement that has a minimum of two terms containing variables or numbers that are equal.
Let x be Teo's age, then Richard's age is 15 years older than twice Teo's age, or 15 + 2x. The combined age of Richard and Teo is 33, so we can write an equation:
x + (15 + 2x) = 33
Simplifying and solving for x, we get:
3x + 15 = 33
3x = 18
x = 6
So Teo is 6 years old and Richard is 15 + 2(6) = 15 + 12 = 27 years old.

(c) Paul uses the function y = 7x + 30 to model the situation. What score does Paul’s model predict for 3 hours of homework?
(d) Describe what the number 30 in Part (c) mean in the context of the situation?
Answers
Answer:
(c) Paul's model predicts a score of 51 for 3 hours
(d) 30 represents the y intercept
Step-by-step explanation:
Given
[tex]y = 7x + 30[/tex]
Solving (c): What is y when x is 3
Substitute 3 for x in [tex]y = 7x + 30[/tex]
[tex]y = 7*3 + 30[/tex]
[tex]y = 21 + 30[/tex]
[tex]y = 51[/tex]
Solving (d): What does 30 represent
An equation is represented as:
[tex]y = mx + b[/tex]
Where
[tex]b = y\ intercept[/tex]
Compare: [tex]y = mx + b[/tex] to [tex]y = 7x + 30[/tex]
[tex]b = 30[/tex]
This implies that 30 represents the y intercept

Nine more than thirty divided by ten. Numerical expression
Answers
The numerical expression for the verbal expression eighteen more than five is (9 + 30) / 10.
What is an expression?An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.
Now the given verbal expression is,
Nine more than thirty divided by ten
Now converting them into numerical expression,
nine = 9
thirty = 30
∵ more than is addition i.e. +
∴ Nine more than thirty = 9 + 30
ten = 10
So, the numerical expression is given as,
Nine more than thirty divided by ten = (9 + 30) / 10
Thus, the numerical expression for the verbal expression eighteen more than five is (9 + 30) / 10.

At the country fair, Maya observes that the wheel of chance has 25 numbered slots. If each play costs a quarter, how much will Maya likely have to spend before she gets her winning number?
Answers
Answer:
6 1/4
Step-by-step explanation:
Given
Total number of wheel chance = 25
Each play = 1 quarter
1 play = 1/4
To calculate the amount Maya has to spend to get her winning number, we will say;
25 plays = x
Divide both expressions
1/25 = 1/4÷x
1/25 = 1/4x
Cross multiply
4x = 25
x = 25/4
x = 6 1/4
This mean that Maya will have to spend 6 1/4 before she gets her winning number
