Pythagorean theorem using side lengths chosen from 3 feet, 4 feet, 5 feet,
and 6 feet.
A. Knowing that 32 +42 = 52, draw the 3-foot side and the 4-foot side
with a right angle between them. The 5-foot side will fit to form a
right triangle.
B. Knowing that 32 +52 + 62, draw the 3-foot side and the 5-foot side
with a right angle between them. The 6-foot side will fit to form a
right triangle.

y = 4x+1
3x + 2y = 13
Please and quickly
Answer:
x=1 and y = 5
Step-by-step explanation:
you add y = 4x+1 into the equation
3x+2(4x+1)=13
3x + 8x + 2 = 13
11x = 11
x = 1
then you just add the x into the equation y = 4x+1
4(1)+1
y = 5

Solve the system of equations below using substitution, elimination or linear combination.
x+2y=−7
3x−8y=7
Answer:
4x+-6y=7
Step-by-step explanation:
hope this helps
Answer:
x= -3
y= -2
Step-by-step explanation:
(1) x + 2y= -7
(2) 3x - 8y= 7
Balance a term in both equations for elimination
Equation (1) x (3) 3x + 6y= -21
Equation (2) x (-1) -3x + 8y= -7
After the calculation, it will result to:
14y= -28
Divide both sides by the coefficient of y
This will result to:
y= -2
From equation (1):
x + 2y= -7
Insert the unit of y (-2)
x + 2(-2)= -7
x - 4= -7
Collect like and unlike terms
x= 4 -7
x= -3
TO CHECK:
3x - 8y= 7
Insert the solved units
3(-3) - 8(-2)= 7
-9 - (-16)= 7
-9 + 16= 7
16 - 9= 7

What are 2 ways i could solve 7-(4p+3)=-3(p+2)-(2p+3)
Answer:
Simplifying
7 + -1(4p + 3) = -3(p + 2) + -1(2P + 3)
Reorder the terms:
7 + -1(3 + 4p) = -3(p + 2) + -1(2P + 3)
7 + (3 * -1 + 4p * -1) = -3(p + 2) + -1(2P + 3)
7 + (-3 + -4p) = -3(p + 2) + -1(2P + 3)
Combine like terms: 7 + -3 = 4
4 + -4p = -3(p + 2) + -1(2P + 3)
Reorder the terms:
4 + -4p = -3(2 + p) + -1(2P + 3)
4 + -4p = (2 * -3 + p * -3) + -1(2P + 3)
4 + -4p = (-6 + -3p) + -1(2P + 3)
Reorder the terms:
4 + -4p = -6 + -3p + -1(3 + 2P)
4 + -4p = -6 + -3p + (3 * -1 + 2P * -1)
4 + -4p = -6 + -3p + (-3 + -2P)
Reorder the terms:
4 + -4p = -6 + -3 + -2P + -3p
Combine like terms: -6 + -3 = -9
4 + -4p = -9 + -2P + -3p
Solving
4 + -4p = -9 + -2P + -3p
Solving for variable 'p'.
Move all terms containing p to the left, all other terms to the right.
Add '3p' to each side of the equation.
4 + -4p + 3p = -9 + -2P + -3p + 3p
Combine like terms: -4p + 3p = -1p
4 + -1p = -9 + -2P + -3p + 3p
Combine like terms: -3p + 3p = 0
4 + -1p = -9 + -2P + 0
4 + -1p = -9 + -2P
Add '-4' to each side of the equation.
4 + -4 + -1p = -9 + -4 + -2P
Combine like terms: 4 + -4 = 0
0 + -1p = -9 + -4 + -2P
-1p = -9 + -4 + -2P
Combine like terms: -9 + -4 = -13
-1p = -13 + -2P
Divide each side by '-1'.
p = 13 + 2P
Simplifying
p = 13 + 2P

Jill is studying a strange bacterium. When she first looks at the bacteria, there are initially.
100 cells in her sample. The next day, there are 300 cells (Day 1). Intrigued, she comes
back the next day to find that there are 900 cells (Day 2)!
bo.
How many bateria cells will there be when Jill looks at her sample on Day 4?
Answer:
8100
Step-by-step explanation:
We first see that in the first day it tripled from 100 to 300 this is the pattern that is seen throughout this whole experemint, we can see that the cells triple again on the second day to get 900 cells from this. It is likely to say that they will triple again on the third day to get 2100 and again on the fourth to get 8100
If a ball is thrown straight up into the air with an initial velocity of 85ft/s its height in feet after t seconds is given by y=85t - 16t^2. Find the average velocity for the time period beginning when t=1 and lasting 0.1, 0.01, 0.001
Answer:
[tex]51.4\ \text{m/s}[/tex]
[tex]52.84\ \text{m/s}[/tex]
[tex]52.984\ \text{m/s}[/tex]
Step-by-step explanation:
The function of displacement is
[tex]y=85t-16t^2[/tex]
[tex]\text{Average velocity}=\dfrac{\text{Total displacement}}{\text{Time elapsed}}[/tex]
Lasting 0.1 s
[tex]v_1=\dfrac{y(1.1)-y(1)}{1.1-1}\\\Rightarrow v_1=\dfrac{85\times 1.1-16\times 1.1^2-(85-16)}{0.1}\\\Rightarrow v_1=51.4\ \text{m/s}[/tex]
The average velocity is [tex]51.4\ \text{m/s}[/tex]
Lasting 0.01 s
[tex]v_2=\dfrac{y(1.01)-y(1)}{1.01-1}\\\Rightarrow v_2=\dfrac{85\times 1.01-16\times 1.01^2-(85-16)}{0.01}\\\Rightarrow v_2=52.84\ \text{m/s}[/tex]
The average velocity is [tex]52.84\ \text{m/s}[/tex]
Lasting 0.001 s
[tex]v_3=\dfrac{y(1.001)-y(1)}{1.001-1}\\\Rightarrow v_3=\dfrac{85\times 1.001-16\times 1.001^2-(85-16)}{0.001}\\\Rightarrow v_3=52.984\ \text{m/s}[/tex]
The average velocity is [tex]52.984\ \text{m/s}[/tex]

On a certain hot summer's day, 232 people used the public swimming pool. The daily prices are $1.50 for children and $2.25 for adults. The receipts for admission totaled $435.75. How many children and how many adults swam at the public pool that day?
Answer:
children is 115 and adult is 117
Step-by-step explanation:
Given
let the number of children be x
and the number of adults be y
so
x+y=232----------------1
We are told that the daily prices are $1.50 for children and $2.25 for adults
so
1.5x+2.25y= 435.75-------------------2
Hence the system of equation for the situation is
x+y=232-----1
1.5x+2.25y= 435.75-------2
From 1 x=232-y
Put this in Eqn 2
1.5(232-y)+2.25y= 435.75
348-1.5y+2.25y= 435.75
collect like terms
-1.5y+2.25y= 435.75-348
0.75y=87.75
divide both sides by 0.75
y= 87.75/0.75
y=117
the number of adults is 117
put y= 117 in eqn 1
x+117=232
x=232-117
x=115
The number of children is 115
deb and luke go to the pi-rate entertainment store to purchase cds (c) and dvds (d). deb buys 3 dvds and 2 cds for $63 (before sales tax) at the same item prices, luke pays $46 for 1 dvd and 4 cds (before sales tax). write and solve a system of equations to determine the cost of 1 cd and dvd
We are given here the individual costs of DVD and CD as well as the total sales and the number of items sold on one day. To solve the number of DVDs and CDs sold each, we devise two independent linear equations:
(1) x + y = 39
(2) 4x + 7y = 204
x- number of DVDs; y - number of CDs
solving, x= 23 DVDs

Students were selected at random in a local high school to see if there was an association between gender and
participation in extracurricular activities. What percent of females participate in extracurricular activities?
(1) 25%
(3) 44%
(2) 53%
(4) 72%
Extracurricular
No Extracurricular
Total
Gender
Male Female Total
24
19 43
16 17 33
40 36 76
===========================================================
Explanation:
The question asks "What percent of females participate in extracurricular activities?" This means we only focus on the second column. There are 36 women, and of this total, 19 are in extracurricular activities.
Dividing the two values leads to approximately 19/36 = 0.52777 which rounds to 0.53
Then we move the decimal to the right two spots to get 53%
Roughly 53% of the female students participate in extracurricular activities.
