Apply the Pythagorean Theorem to determine whether or not the given triplets represent right triangles or not:
I. 5 feet and 13 feet: 5^2 + 12^2 = 13^2 is TRUE
II. 9 ft and √63 ft: 9^2, 63, 12^2: 63 + 81 do add up to 144 TRUE

Job 1 the base pay is 30 and the job pay 150 total for an 8 hour day job 2 y=17x+25 which one pays more
Answers
Answer:
Job 2
Step-by-step explanation:
Find how much job 1 pays for 1 hour:
(150 - 30) ÷ 8 = 15
Job 1 pays $15 per hour.
Assuming variable x stands for number of hours worked, job 2 pays $17 an hour.
Put job 1 into a similarly formatted equation:
Variable y = total pay
y = 15x + 30
Compare job 1 and 2:
Job 1: 15x + 30
Job 2: 17x + 25
Just by looking at the two expressions, there is no obvious higher paying job so let's try plugging in 8 hours for x:
15(8) + 30 = 150
17(8) + 25 = 161
$161 is more than $150 so job 2 pays more.

You lose 0.3 point for stepping out of bounds during a gymnastics floor routine. Your final score is 9.124. Write and solve an equation to find your score x without the penalty.
Answers
The equation is x + 0.3 = 9.124 and the value of x is 8.824.
The following is a linear equation in one variable. It can be expressed in the form of ax+b=0. Here a and b are integers and x is a variable that has only one solution. In these type of equations only one variable is present.
We can write an equation to find the score without the penalty by using the information provided. Let x be the score without the penalty. We know that the final score (with the penalty) is 9.124 and that the penalty is 0.3 points. Therefore, we can set up the equation:
x + 0.3 = 9.124
To find the score without the penalty, we need to subtract 0.3 from both sides of the equation:
x = 9.124 - 0.3
x = 8.824
So, the score without the penalty is 8.824

What is the value of x between the two triangles? *no bots or else you will be reported*
Answers
Answer:
x = 25
Step-by-step explanation:
First we need to show that these two triangles are similar. Add up the angles 68 and 38 degrees in the first triangle, and then subtract this sum from 180 degrees. This results in 74 degrees, which matches 74 degrees in the second triangle.
Next we write and solve an equation of ratios:
6 10
----- = -------
15 x
Cross multiplying returns 6x = 150, so that x = 25.
Note that 6/15 is the ratio of the shortest sides, and 10/x is the ratio of the longest sides.

An object is launched at an upward velocity of 9696 feet per second from the top of a building 160160 feet above the ground. Use the vertical motion model h=-16t^{2}+vt+c, where hh is the ending height of the object, cc is the initial height, in feet, of the object, tt is the time in seconds, and vv is the velocity of the object.
How long will it take the object to reach the maximum height and what is the maximum height? Fill in the blanks with the appropriate values.
Answers
The time that it will take for the object to reach maximum height is given as follows:
3 seconds.
The maximum height is given as follows:
304 feet.
How to model the object's height?The object's height is modeled by a quadratic function in the following format:
h = -16t² + v(0)t + h(0).
In which:
v(0) is the initial velocity.h(0) is the initial height.The parameters for this problem are given as follows:
v(0) = 96, h(0) = 160.
Hence the function is defined as follows:
h(t) = -16t² + 96t + 160.
Meaning that the coefficients of the quadratic function are given as follows:
a = -16, b = 96, c = 160.
The coefficient a is negative, meaning that this is a concave down quadratic function, thus the vertex of the quadratic function represents the maximum height.
The t-coordinate of the vertex is given as follows:
t = -b/2a = -96/-32 = 3 seconds.
Then the maximum height is of:
h(3) = -16(3)² + 96(3) + 160
h(3) = 304 feet.

The parameters are given by:
n is the number of trials of the experiment.p is the probability of a success on a single trial of the experiment.The parameter values for this problem are given as follows:
n = 20, as the band has 20 members.p = 1/365, as the year has 365 days, hence the probability of a person having a given day as a birthday is of 1/365.The probability that all members have different birthdays is of P(X = 0), hence:
P(X = 0) = (1 - 1/365)^20 = 0.9466.

2. ) Jada thinks that if she gets at least 92 out of 100 on the final test, she will get an A in the class. Do you agree? Explain
Answers
1) Jada does not have 90% of the total possible points before the final test.
2) If Jada gets at least 92 out of 100 on the final test, she will not get an A in the class.
From the following table of Jada’s results before the final test in the class the total number of points possible:
150 + 100 + 100 + 100 = 450
And Jada’s total points before the final test:
141 + 87 + 81 + 91 = 400
To check whether Jada have 90% of the total possible points before the final test, we find the percentgae of Jada’s total points.
(400/450) × 100 = 88.89%
This means, Jada does not have 90% of the total possible points before the final test.
After final test, the total number of points possible: 450 + 100 = 550
And if she gets at least 92 out of 100 on the final test, her total points would be,
400 + 92 = 492
And the percentgae of Jada’s total points would be,
(492/550) × 100 = 89.45%
Given that Jada needs to have at least 90% of the total number of points possible.
so, she will notl get an A in the class.

A catering company is setting up tables for a big event that will host 764 people when they set up the tables they need 2 forks for each child and 5 forks for each adult the company ordered a total of 2992 forks set up a system of equations involving the number of adults,a and the number of children,c and solve to find out how many of each attended the event
Answers
Answer:
488 adults and 276 children
Step-by-step explanation:
So, we need two linear equations here to start, and we do have them.
Our first linear equation tells us how we get the number of forks:
2c + 5a = 2992
And the second tells us the number of people there:
c + a = 764
I will solve this using substitution. We start by minusing a from both sides in the second equation, giving us:
c = 764 - a
Then, we will substitute this into our first equation, giving us:
2(764 - a) + 5a = 2992
Then, we will open the parentheses, giving us:
1528 - 2a + 5a = 2992
Combining like terms and subtracting 1528 from both sides gives us:
3a = 1464
Dividing by 3:
a = 488
So there were 488 adults. Then, we take our original second equation and substitute 488 for a, giving us:
488 + c = 764
Minus 488 from both sides gives us:
c = 276
So, there were 276 children. In total, we had 488 adults and 276 children.

Answers
Answer : in California there are 24 volcanoes while in Alaska there are 36 volcanoes.
Step-by-step explanation:
Total number of volcanoes = 60.
40% of the volcanoes where in California.
i.e 100% - 40% = 60%.
60% of the volcanoes were in Alaska.
In California = 40/100 × 60 = 24 volcanoes.
In Alaska = 60/100 × 60 = 36 volcanoes.

Step-by-step explanation:

Marty's function has the larger slope of 1/3.
What is meant by slope of a line ?The slope of a line is computed as the ratio of the change in the y-axis to the change in the x-axis.
Marty's equation is given as,
y + 3 = 1/3(x + 9)
The equation for point slope form is,
y - y₁ = m(x - x₁)
Where, m is the slope of the line.
So, m = 1/3
Consider a function written by Ethan,
(-4, 9.2) and (-2, 9.6)
Slope of the line,
m = (y₂ - y₁)/(x₂ - x₁)
m = (9.6 - 9.2)/(-2 - -4)
m = 0.4/2 = 0.2
Hence,
Marty's function has the larger slope of 1/3.
