What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Boyle's law is given by:
P₁V₁ = P₂V₂
Where P is pressure and V is volume. Hence:
12(3) = 6 * P₂
P₂ = 6 atm

P1V1=P2V212(3)=6P_236=6P_2P_2=6atmSuppose angle A and angle B are supplementary.
The measure of angle A is (15x + 65) and the measure of angle B is (50x - 15).
Solve for x (showing your setup and work) and then find the measure of angle A and the measure of angle B
Answer:
x = 2
Angle A = 95°
Angle B = 85°
Step-by-step explanation:
Concepts
Supplementary angles are angles that sum up to 180° to form a straight angle.
Application
We are asked to find the value of x, Angle A, and Angle B. We are given angles A and B as 15x + 65 and 50x - 15. To do this, we can set up the equation 15x + 65 + 50x - 15 = 180 because we know these angles are supplementary, or adding to 180°. Then, once we get the value of x, we plug in that value for each angle.
Solution
Step 1: Simplify both sides.
[tex](15x+50x) +(65-15)=180[/tex] [tex]65x+50=180[/tex]Step 2: Subtract 50 from both sides.
[tex]65x+50-50=180-50[/tex] [tex]65x=130[/tex]Step 3: Divide both sides by 65.
[tex]65x/65 = 130/65[/tex] [tex]x=2[/tex]Step 4: Plug x into angle A.
[tex]15(2)+65 = 30 + 65 = 95[/tex]Step 5: Plug x into angle B.
[tex]50(2) - 15 = 100 - 15 = 85[/tex]
Solve the inequalities -150x ≥ − 2,400 and -336 ≥ − 21y.
x<
y >
Answer:
x ≤ 16y ≥ 16Step-by-step explanation:
-150x ≥ − 2,400
[tex]\Longrightarrow -\frac{1}{150} \times \left( -150\right) x \leq -\frac{1}{150} \times \left( -2400\right)[/tex]
[tex]\Longrightarrow x\ \leq \frac{-2400}{-150}[/tex]
[tex]\Longrightarrow x\ \leq 16[/tex]
===============
-336 ≥ − 21y
[tex]\Longrightarrow -\frac{1}{21} \times \left( -336\right) \leq -\frac{1}{21} \times \left( -21\right)y[/tex]
[tex]\Longrightarrow 16\geq y[/tex]

The information in the table shows the average weekly temperatures in degrees Fahrenheit of four cities.
Which city’s data set is bimodal?
A. City A
B. City B
C. City C
D. City D
Finding the mode of each data-set, the bimodal city's data is given by:
C. City C.
What is the mode of a data-set?It is the value that appears the most times in the data-set. If two values appear the same number of sets, the data-set is called bimodal.
Hence, looking at the table:
For City A, 10 appears three times, hence it is the only mode.For City B, 25 appears five times, hence it is the only mode.For City C, 42 and 66 each appear three times, hence they are the modes, and the data-set is bimodal.For City D, 78 appears three times, hence it is the only mode.Hence option C is correct.

Juan borrowed $10 from his cousin. He borrowed another $30 from his uncle. Juan bought a $10 lottery ticket and won $100. How much money will Juan have after he pays his cousin and uncle back?
Answer:
$90
Step-by-step explanation:
Since Juan pays back the $10 and $30 he borrowed from his cousin and uncle they do not affect the total outcome ($10+$30-$10-$30=0)
Subtract the price of the ticket from the total amount he won.
$100-$10=$90

Suppose that 2 ≤ f '(x) ≤ 4 for all values of x. What are the minimum and maximum possible values of
f(5) − f(1)?
Answer:
Step-by-step explanation:
By the Mean Value Theorem, there is at least one number, c, in the interval (1,6) such that
f'(c) = [f(6) - f(1)]/ (6 - 1)
So, f(6) - f(1) = 5f'(c).
Since 2 ≤ f'(c) ≤ 4, 10 ≤ 5f'(c) ≤ 20
So, f(6) - f(1) is between 10 and 20.

Suppose y varies directly with x. If y is 8 when x is 12, find y when x is 18.
[tex]\large\textsf{\textbf{Answer\::}}[/tex]
Please consult the "calculations" section of this ans .
[tex]\large\textsf{\textbf{Calculations\::}}[/tex]
If y varies directly with x , the equation looks like this :
y=kx , where k is the constant of proportionality
Plug in the values :
8=k/12
Multiply times 12 on both sides :
96=k
So the constant of proportionality is 96 .
Now solve for y when x is 18 as follows :
y=96/18
y≈5.33

there are 1800 pupils in a school of witch 2/5 are girls. 540 of the pupils do not play sports. Of these pupils who do not play sports, 5/9 are girls. How many boys play sports?
========================================================
Explanation:
There are 1800 students total.
Take 2/5 of this to find the number of girls
(2/5)*1800 = 720 students are girls
Subtract that result from the total to get the number of boys
1800-720 = 1080 students are boys
We'll use this value later, so let A = 1080.
-------------
540 students do not play sports
(5/9)*540 = 300 girls do not play sports.
540-300 = 240 boys do not play sports
Let B = 240
------------
We found that
A = 1080 boys totalB = 240 boys do not play sportsTherefore,
A-B = 1080 - 240 = 840 boys play sports

Given:
[tex]\frac{u*v}{||u|| ||v||}[/tex]
If θ is the angle between u and v, then
u • v = ||u|| ||v|| cos(θ)
Since u = -3v, we have
u • v = (-3v) • v = -3 ||v||²
and
||u|| = ||-3v|| = 3 ||v||
If v₁ and v₂ are both not zero, then ||v| ≠ 0.
Then
cos(θ) = (-3 ||v||²) / (3 ||v|| ||v||) = 1
which means θ = π rad = 180°.
