Which of the given numbers is not a Pythagorean triplets. *
1 point
8,15,17
9,40,41
4,7,8
Step-by-step explanation:
By Pythagoras' Theorem,
[tex] {c}^{2} = {a}^{2} + {b}^{2} [/tex]
where c is always the largest number.
a and b can be interchangeable between the 2nd largest and the 3rd largest numbers.
Given a = 8, b = 15 and c = 17,
[tex] {a}^{2} + b {}^{2} = {8}^{2} + {15}^{2} \\ = 64 + 225 \\ = 289 \\ \\ {c}^{2} = {17}^{2} \\ = 289[/tex]
Since c^2 = a^2 + b^2 , 8 , 15 and 17 are pythagorean triplets.
Now let's move on to 9, 40 and 41.
[tex] {a}^{2} + {b}^{2} = {9}^{2} + {40}^{2} \\ = 81 + 1600 \\ = 1681 \\ \\ {c}^{2} = {41}^{2} \\ = 1681[/tex]
Since c^2 = a^2 + b^2 , 9 , 40 and 41 are pythagorean triplets.
Last let's move on to 4,7 and 8.
[tex] {a}^{2} + {b}^{2} = {4}^{2} + {7}^{2} \\ = 16 + 49 \\ = 65 \\ \\ {c}^{2} = {8}^{2} \\ = 64 [/tex]
Since a^2+b^2 IS NOT EQUAL to c^2, 4,7 and 8 ARE NOT pythagorean triplets.

A train travels 73 1/3 miles in 3/2 hour. What is its speed in miles per hour?
Speed per hour = distance / time
Speed = 73 1/3 / 3/2
Speed = 220/3 / 3/2
Speed = 220/3 x 2/3
Speed = 440 /9
Speed = 48 8/9 miles per hour.

Which is a zero of x2 − 8 = 2x?
Answer:
The zeros are x=4, -2
Step-by-step explanation:
Its zeros can be found by setting the function to zero. The values of x that represent the set equation are the zeroes of the function. To find the zeros of a function, find the values of x where f(x) = 0.

51 is greater than or equal to x
Question Options:
51 < x
51 > x
51 ≥ x
51 ≤ x
Please explain as well, thanks!
Answer:
51 ≥ x
Step-by-step explanation
The greater than or equal to sign is a symbol that indicates that the value on the left hand side of the symbol is either greater than, or equal to the value on the right. This can also be read as the value on the left hand side is at least equal to the value on the right. X can equal 51 or it can be less. X cannot be greater than 51 in this inequality
Among 500 freshmen pursuing a business degree at a university, 311 are enrolled in an economics course, 243 are enrolled in a mathematics course, and 135 are enrolled in both an economics and a mathematics course. What is the probability that a freshman selected at random from this group is enrolled in each of the following?
a) an economics and/or a mathematics course.
b) exactly one of these two courses.
c) neither an economics course nor a mathematics course.
Solution :
Let A = Economics, B = Mathematics
n(A) = 311, n(B) = 243, [tex]$n(A \cap B) = 135$[/tex]
a). So, [tex]$n(A \cup B) = n(A) +n(B) - n(A \cap B)$[/tex]
= 311 + 243 - 135
= 419
b). n(A only) = 311 - 135
= 176
n(B only) = 243 - 135
= 108
Exactly one of these two courses
[tex]$=\frac{176+108}{500}$[/tex]
= 0.568
c). Neither economics nor mathematics
[tex]$=\frac{500-419}{500} $[/tex]
[tex]$=\frac{81}{500}$[/tex]
= 0.162
y = 3x^2 - 4x
27 + y = 14x
Step-by-step explanation:

[tex]y = 14x - 27[/tex]
use this equation and substitute it into the y value of the first equation

x= 8-3 = 5
k = 7.5/5 = 1.5
in the dark forest a rare species of spiders called Acromantula is doubling every 4 years. there are currently 50 spiders, how many spiders will be in the forest after 20 years?
Answer:
1600. Because 20/4is 5 so there is 5time doubling so
first time 50 to 100
second time 100 to 200
third 200to400
fourth 400to 800
fifth 800to 1600.
In 20 years the number of Acromantula will be 1600 if the number of Acromantula is doubling in every 4 years.
What is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given, the number of Acromantula doubles in every 4 years.
Also given that, There are 50 Acromantula in the forest.
In 4 years, the number of Acromantula wil be double of 50 i.e., 100
In 8 years, the number of Acromantula will be double of 100 i.e., 200
In 12 years, the number of Acromantula will be double of 200 i.e., 400
In 16 years, the number of Acromantula will be double of 400 i.e., 800
In 20 years, the number of Acromantula will be double of 800 i.e., 1600
Hence, In 20 years the number of Acromantula will be 1600

You work as a residential painter. A customer wants two tables and eight chairs painted using one coat of the same color paint. Each table requires 15858 quarts of paint, and each chair requires 2323 quarts of paint. How many total quarts of paint should you bring to paint this furniture?
Step-by-step explanation:
Let t be the number of tables
Let c be the number of chairs
Total paint needed = 15858t + 2323c
Given t = 2 and c = 8, substitute t and c into expression to find total paint needed
Total Paint needed = 15858(2) + 2323(8)
= 31716 + 18584
= 50300 quarts of paint
How does using the properties of addition makes a problem easier to solve
9514 1404 393
Answer:
properties of addition let you add, subtract, or rearrange the terms of a sum as may be needed
Step-by-step explanation:
Properties of addition let you rearrange a sum to make addition easier to do or to check mentally. They also let you "undo" addition or subtraction in the process of solving algebra problems. And, they let you add terms or constants that may make it easier to rearrange expressions, as in "completing the square."
