Pythagorean Theorem: a² + b² = c²
Insert 3 and 5 into the equation3² + 5² = c²
Simplify3² = 9
5² = 25
9 + 25 = 34
34 = c²

1.) To find c, you must fill in the formula:Formula: [tex]a^2+b^2=c^2[/tex][tex]a^2=3^2[/tex][tex]b^2=5^2[/tex]- When finding c, it doesn't matter what you put for a or b. So if you want to make a = 5, and b = 3, it wouldn't make any difference.
2.) Find the powers of a and b:[tex]3^2=9[/tex][tex]5^2=25[/tex]3.) Add a and b together:[tex]9+25=34[/tex]______________________________

A board is 48 in long. It must be divided into 4 pieces of equal length, and each cut will cause a waste of 3/16 in. How long will each piece be after the cuts are made?
Answer:
12 pieces
Step-by-step explanation:
Total length of the board = 48 in
It must be divided into 4 pieces of equal length
This means, there will be 3 cut to have 4 pieces
Each cut will cause a waste of 3/16 in.
Total waste = 3 cut × 3/16 in
= (3*3)/16
= 9/16 in
Length of board remaining = Total length of the board - Total waste
= 48 - 9/16
= (768-9)/16
= 759/16 in
How long will each piece be after the cuts are made?
Length of each piece after the cut = Length of board remaining / 4
= 759/16 ÷ 4
= 759/16 × 1/4
= 759/64
= 11.859375
Approximately 12 pieces to the nearest whole number
find the value of x in the triangle below
Answer:
87 degrees
Step-by-step explanation:
the three angles of a triangle add up to one hundred eighty degrees.
1. Add the degrees of the known angles together
56 + 37 = 93
2. Since a triangle adds up to one hundred eighty degrees, you would subtract your known degrees from the total
180 - 93 = 87

The seventh grade class is putting on a talent show to raise money for a class trip. It costs $500 to rent the banquet hall they are planning on using. If they charge $15 per ticket, how many tickets do they need to sell in order to raise at least $1000? Part A The variable in this problem will represent the number of Part B Choose the correct inequality to represent the story problem
Answer:
Part A; 15x
Step-by-step explanation:
Part A; 15(67)
= $1005
Part B; ??
The number of tickets to be sold if, The cost of the banquet hall is $500, The cost per ticket is $15, the Total money to be raised is $1000, is 67, and the equation is given by 1000 = 15x.
What is the equation?Equation: A declaration that two expressions with variables or integers are equal. In essence, equations are questions and attempts to systematically identify the solutions to these questions have been the driving forces behind the creation of mathematics.
In other terms, it is a mathematical statement stating that "this is equivalent to that."
Given:
The cost of the banquet hall = $500,
The cost per ticket = $15,
Total money to be raised = $1000
Write the equation of the number of tickets as shown below,
1000 = 15x
Here, x is the number of tickets,
x = 1000 / 15
x = 66.67 or 67

x=3y-1
3x+4y=10
Answer:
y=1, x=2
Step-by-step explanation:
so first solve for y. plus x=3y-1 into the other equation.
so 3(3y-1)+4y=10.
Simplify
9y-3+4y=10 Add 3 to both sides
9y+4y=13 Add
13y=13 . Divide 13 from both sides
y=1

Answer:
D. x>-3
Step-by-step explanation:
Since the dot on -3 is not shaded in we know it is not ≤ or ≥ so option A and C are eliminated.
Remember if the arrow is pointing to the left (<-----) Then it is Less-than which is <.
If the arrow is pointing to the right (----->) Then it is Greater-than which is >.
Since the arrow is pointing right the answer will be x>-3 which is D

Answer:
y = -2x + 12
Step-by-step explanation:
Step 1: find the slope
y = 1/2x + 5
The equation of the line is
y = mx + c
m - slope
m = 1/2
Note : if two lines are perpendicular to the other, both lines are negative reciprocal of each other
m = -2
Step 2 : using a point slope form
y - y1 = m( x - x1)
( 2 , 5)
x1 = 2
y1 = 5
y - 2 = -2( x - 5)
y - 2 = -2x + 10
y = -2x + 10 + 2
y = -2x + 12
The equation of the line is
y = -2x + 12

What is a proportional relationship?Proportional relationships are relationships between two variables where their ratios are equivalent.
The given table is
Cell Phone Towers Customers (thousands) Towers
3.25 169
4.25 221
5.25 273
7.25 377
Here, the ratio of Cell Phone Towers : Customers (thousands) Towers
3.25 : 169
= 325/16900
= (325÷325)/(16900÷325)
= 1/52
4.25 : 221
= 425/22100
= 1/52
5.25 : 273
= 525/27300
= 1/52
7.25 : 377
= 725/37700
= 1/52
Therefore, the ratio of given cell phone towers to customers (thousands) towers are equivalent.
