Answer:
the diagonal of any rectangular prism is always longer than any one side because the diagonal is the hypotenuse
The triangle is a right triangle because the square of the longest side equals the sum of the squares of the shorter sides.
What is the right triangle?A right-angle triangle is a triangle that has a side opposite to the right angle the largest side and is referred to as the hypotenuse.
here, we have,
A triangle with side lengths 7, 80, and 31 is given.
We need to find that the triangle is right-angled.
By Pythagoras theorem,
(Hyp)² = (Opp)² + (Adj)²
(Hyp)² = (80)² = 6400
(Opp)² + (Adj)² = 7² + 31²
= 49 + 961
= 1,010
Therefore, (Hyp)² > (Opp)² + (Adj)²
Yes, the triangle is a right triangle because the square of the longest side equals the sum of the squares of the shorter sides.

Which of these systems of equations would be best solved using the subtraction method?
I. 2x−7y+3y = 4 −6x−4y = −52
II. 2y = −5x+6x−5 y = 2x−6
III. −7x+3x+2y = 4 4x−6y = −52
Answer:
Step-by-step explanation:
1. x+2y=6 or x=6-2y
3x-2y=2
3(6-2y)-2y=2
18-6y-2y=2
18-8y=2
-8y=-18+2
-8y=-16
y=-16/-8
y=2 ans.
x+2*2=6
x+4=6
x=6-4=2 ans.
Proof:
3*2-2*2=2
6-4=2
2=2
I leave the rest for you to practice with.
3. 4x+y=7
2x+5y=-1
5. 3x+2y=-2
6x-y=6
Solve the system using the elimination method. Show all your steps.
7. -3x+3y=3
3x+y=9 add.
---------------------------------
4y=12
y=12/4
y=3 ans.
3x+3=9
3x=9-3
3x=6
x=6/3
x=2 ans.
Proof:
-3*2+3*3=3
-6+9=3
3=3
I'll leave the rest for practice.
9. -5x+12y=20
x-2y=-6
11. 3x+2y=1
4x+ 6y= 7

The local business will donate $5.00 for every 10 tickets sold. Let x represent tickets sold, and y represent dollars donated. Student A claims that the equation is y = 2x. Student B claims that the equation is y = 1
2
x. Explain who is correct.
Answer:
If we let x be the number of ticket sold and y be the amount in dollars donated then, the equation would be,
x = 2y
We can check our answer by substituting the given,
10 = 2(5)
10 = 10
The equation can also be written as,
y = (1/2)x
Student B is correct.
Answer:
Sample Response/Explanation: The point that represents what the local business will donate is (10, 5). After testing the point in both equations, you can see that student B wrote the correct equation; 5 = 12(10).

The tree diagram shows the sample space of two-digit numbers that can be created using the digits 9,2 1, and 8. What is the probability of choosing a number from the sample space that contains both 2 and 8?
Answer:
Given : the sample space of two-digit numbers that can be created using the digits 9,7,1, and 8.
To Find : probability of choosing a number from the sample space that contains both 7 and 8.
Solution:
TREE DIAGRAM
9 7 1 8
↓ ↓ ↓ ↓
------------------- ---------------- ----------------- ---------------
↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓
9 7 1 8 9 7 1 8 9 7 1 8 9 7 1 8
Total Sample space = 16
Contains both 7 and 8
is ( 7 , 8) or ( 8 , 7)
Hence probability of choosing a number from the sample space that contains both 7 and 8. = 2/16
= 1/8
= 12.5 %

HALP PLEASE DO 6 AND 7 PLEASEEE
Answer:
Step-by-step explanation:
6) Convert mixed fraction to improper fraction and then plugin the values in the formula.
[tex]l= 3\frac{1}{3} yard=\frac{10}{3}\\\\w = 1\frac{5}{9} yard=\frac{14}{9}\\\\h =2\frac{1}{4} yard=\frac{9}{4}\\\\Volume of wood shed = l * w *h\\\\= \frac{10}{3}*\frac{14}{9}*\frac{9}{4}\\\\= \frac{5}{3}*\frac{7}{1}*\frac{1}{1}\\\\=\frac{5*7}{3}\\\\=\frac{35}{3}\\\\=11\frac{2}{3} cubic yard[/tex]
b) 10 cubic yard is less than 11 2/3 cubic yard. So, it will fit in the wood shed.
7) Right side rectangular prism:
l = 16 in
w = 5 in
h = 20 - 14 = 6 in
Volume 1 = 16 * 5 * 6 = 480 cubic inches
Left side rectangular prism:
l = 9 in
w = 5 in
h =14 in
Volume 2 = 9 * 5 * 14 = 630 cubic in
Volume of composite solid = 480 + 630 = 1110 cubic inches

Step-by-step explanation:
A function f(x) is shown below.
f(x) = x + x + x
Write an equivalent form of f(x) in function notation that contains only one term on the right side of the equation.
Answer:
f(x) = 3x
Step-by-step explanation:
when adding x (the same variable) to eachother when there is nothing in front, you always assume the coefficient is 1. since there are 3 x's, (1)x+(1)x+(1)x=3x. hope this helps:)
