If p and q vary inversely and p is 9 when q is 16, determine q when pis equal to 18.
Answer:
[tex]p \: \alpha \: \frac{1}{q} \\ p = \frac{k}{q} \\ k \: is \: a \: constant \: of \: proportionality \\ when \: p \: is \: 9.. \: \: q = 16 \\ 9 = \frac{k}{16} \\ k = 144 \\ when \: p \: is \: 18 : \\ 18 = \frac{144}{q} \\ q = \frac{144}{18} \\ q = 8[/tex]

2. Find the base of a triangle which has an area of 2 1/4 square inches, and a height of 1/8 in.
Answer:
36 inches
Step-by-step explanation:
Given data
Area of triangle =2 1/4 square inches
Area =9/4 square inches
Height of triangle =1/8 inches
We know that the expression for the area of triangle is
Area = 1/2Base *Height
9/4=1/2*Base *1/8
9/4=Base/16
Cross multiply
16*9=Base*4
144=Base*4
Base =144/4
Base=36 inches

If carpet costs $11 a square yard including padding and installation, what would it
cost to carpet a room measuring 14ft. by 20ft? (Note: 3 feet = 1 yard)
Round to the nearest dollar.
$1386
o $374
$342
o $1027
o$3080
Answer:$342
Step-by-step explanation: First we convert to yards: which gives us 14/3 yards and 20/3 yards. We multiply these to find a combined area of 280/9 yards, which we then multiply to get 280*11/3. Simplify to get 342.22 repeating, which rounds to 342.

Pleasee help with this question asap I’m begging y’all
==================================================
Work Shown:
[tex]y = \frac{4x+30}{x+5}\\\\y = \frac{4x+20+10}{x+5}\\\\y = \frac{(4x+20)+10}{x+5}\\\\y = \frac{4(x+5)+10}{x+5}\\\\y = \frac{4(x+5)}{x+5}+\frac{10}{x+5}\\\\y = 4+\frac{10}{x+5}\\\\[/tex]
Therefore, a = 10
--------------
As an alternative approach, we could work in reverse like this:
[tex]y = 4+\frac{a}{x+5}\\\\y = 4*\frac{x+5}{x+5}+\frac{a}{x+5}\\\\y = \frac{4(x+5)}{x+5}+\frac{a}{x+5}\\\\y = \frac{4(x+5)+a}{x+5}\\\\y = \frac{4x+20+a}{x+5}\\\\[/tex]
Then notice that the 20+a must be 30, so solving 20+a = 30 leads to a = 10
--------------
As yet another alternative approach (well I suppose it's actually 2 extra approaches) we could use either polynomial long division or synthetic division. Either way, you should end up with a remainder of 10, which corresponds directly to a = 10

Answer:
B, C, D
Step-by-step explanation:
You can solve for x, or you can try x=3.5 to see if that makes the equation true. Here, we decided to solve for x.
A. x =(8×3 -3)/7 = 3
B. x = 15 -11.5 = 3.5
C. x = (34 -6)/8 = 3.5
D. x = 15.5 -12 = 3.5
E. x = 20 -15.5 = 4.5
(NEED HELP ASAP) The map is similar to the map from the previous unit. The x-axis runs from -110 to +110. For the y-axis, the values run from -80 to +80. Each tick mark on the axes has the value of 5 m (so each square on the grid represents 10 m). The additional path, Archimedes Alley has been added to the map.
The standard form for one of the three equations is 9x - 20y - 900 = 0.
i) Determine the x- and y-intercepts for the line.
ii) Identify its equivalent equation in slope y-intercept form.
iii) Explain how you chose the equation in slope y-intercept form.

A power company calculates a person's monthly bill from the number of
kilowatt-hours (kWh), x, used.
The function b(x) = {
0.15x,
x < 200
0.10 (x - 200) + 30, 2 > 200
determines
the bill.
How much is the bill for a person who uses 700 kWh in a month?
A. $100
оо
B. $80
O C. $105
O D. $95
PREVIOUS
Answer: (b)
Step-by-step explanation:
Given
Function for bill calculation is
[tex]\Rightarrow b(x)=\left \{ {{0.15x\quad \quad \quad \, \ \ \ \ x<200} \atop {0.1(x-200)+30\quad x>200}} \right.[/tex]
The consumption is 700 kWh i.e. more than 200
Therefore, bill is given by the second function i.e. [tex]0.10(x-200)+30[/tex]
Substitute 700 for x to get the bill
[tex]\Rightarrow 0.1(700-200)+30\\\Rightarrow 50+30=\$80[/tex]
Hence, option (b) is correct.

What is the total Jeff has a painted
A. 180 square inches
B.40 square inches
C.100 square inches
D.90 square inches
Answer:
180 square inches
Step-by-step explanation:
let separate the figure and form two rectangles
first rectangle
length = 10 in
breadth = 9 in
let's find its area
area =l*b
=10*9
=90 in.^2
second rectangle
length = 15 in.
breadth = 6 in.
area =l*b
=15 *6
=90 in.^2
area of a whole he painted =area of first rectangle + area of second rectangle
=90 + 90 in.^2
=180 in .^2

You roll a number cube. Find the probability and write your answer in the simplest form. P(4)= ------------------------------------------- P(not a 2) = ------------------------------------ P(3 or 5) = ------------------------------------
Answer:
[tex]P(4) = \frac{1}{6}[/tex]
[tex]P(\text{not a 2}) = \frac{5}{6}[/tex]
[tex]P(\text{3 or 5}) = \frac{1}{3}[/tex]
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Number cube:
A number cube is a dice, which has six sides, numbered 1 to 6.
P(4)
One the sides is a 4, thus:
[tex]P(4) = \frac{1}{6}[/tex]
P(not a 2)
Of the 6 sides, one is a 2, and the other 5 are not 2. So
[tex]P(\text{not a 2}) = \frac{5}{6}[/tex]
P(3 or 5)
One sides is 3, other is 5, 1 + 1 = 2. So
[tex]P(\text{3 or 5}) = \frac{2}{6} = \frac{1}{3}[/tex]
