Answer:
C. 891.
Step-by-step explanation:
This is a regular nonagram ( has 9 sides) so the area is the sum of 9 congruent triangles.
Area of a triangle = 1/2 * base * height
Area of 1 triangle in this polygon = 1/2 * 12 * 16.5
Area of the polygon = 9 * 1/2 * 12 * 16.5
= 891

m = 3/4 and b = -2
Slope-intercept Form: y = 3/4*x -2
If the teacher wants to show work you would have to use a point-slope form using those two points to solve m. Then using a point and slope plug that into the point-slope form and make it into slope-intercept form.

mohsin purchased a 30 ounce bag of dried Turkish figs for $11.40. What is the cost per pound?
Answers
Answer:
$6.08 per pound
Explanation:
30 ounce ⇒ $11.40
conversions:
16 ounce ⇔ 1 pound1 ounce ⇔ 0.0625 poundsolve:
0.0625(30) pound ⇒ $11.401.875 pound ⇒ $11.401 pound ⇒ $6.08Answer:
$6.08
Step-by-step explanation:
Mohsin purchased a 30-ounce bag of dried Turkish figs for $11.40.
⇒ 30 ounces of dried Turkish figs = $11.40
Finding the cost per ounces:
30 ounces of dried Turkish figs/30 = $11.40
⇒ 30 ounces of dried Turkish figs/30 = $11.40/30
⇒ 1 ounce of dried Turkish figs = $0.38
Finding the cost per pounds:
1 pound ↔ 16 ounces
⇒ 1 ounce of dried Turkish figs = $0.38
⇒ 1 ounce of dried Turkish figs × 16 = $0.38 × 16
⇒ 16 ounces of dried Turkish figs = $6.08

Brianna has $620 to spend at a bicycle store for some new gear and biking outfits. Assume all prices listed include tax.
She buys a new bicycle for $261.04.
She buys 3 bicycle reflectors for $13.07 each and a pair of bike gloves for $13.57.
She plans to spend some or all of the money she has left to buy new biking outfits for $51.03 each.
Write and solve an inequality which can be used to determine xx, the number of outfits Brianna can purchase while staying within her budget.
Answers
Answer: 6 outfits
Step-by-step explanation:
$620 should be greater than the price of the new bicycle + 3 * bicycle reflectors + a pair of bike gloves + unknown number of biking outfits
Therefore, the inequality will be:
620 ≥ 261.04 + 3 × 13.07 + 13.57 + 51.03x
620 ≥ 313.82 + 51.03x
[tex]\text{Solving \ for \ x}[/tex]
[tex]620\ge \:313.82+51.03x[/tex]
[tex]\mathrm{Switch\:sides}[/tex]

[tex]\mathrm{Multiply\:both\:sides\:by\:}100[/tex]

HELP ME OUT PLS AND HAVE A SHORT ANSWER PLS!!!!!!!
Anthony's sink is shaped like a half-sphere, and it has a volume of 5121 cubic inches. It is completely full of water, and he has two different cylindrical cups he can use to scoop it out. The blue cup has a diameter of 4 in. and a height of 8 in., and the green cup has a diameter of 8 in. and a height of 8 in.. How many cupfuls of water will it take for him to empty his sink using each cup? In your answer, give the number of cupfuls it will take to empty the sink using each cup, and then explain how you calculated it. (NOTE: Type out your work & write out your explanation for full credit.)
Answers
By taking the quotient between the volumes, we conclude that he must use the blue cup 16 times or the green cup 4 times.
How many times does he need to use each cup?
The volume of the sink is 512π in^3.
The blue cup is a cylinder of diameter = 4 in and a height = of 8 in, then its volume is:
V = π*(4in/2)^2*8in = 32π in^3
The number of times that he needs to use this cup is given by:
N = (512π in^3)/(32π in^3) = 512/32 = 16
He needs to use 16 times the blue cup.
The green cup has a diameter =of 8in and a height = of 8in, then its volume is:
V' =π*(8in/2)^2*8in = 128π in^3
The number of times that he must use this cup is:
N' = (512π in^3/ 128π in^3) = 512/128 = 4
He needs to use 4 times the green cup.

Suppose the income tax rate is 10% for the first $7500 plus 15% for the amount over $7500
How much must Dan pay in income tax for last year?
Answers
well, we know is 10% for the first 7500, but Dan only made 5000 of taxable income, so he's in that range of 0 - 7500, so he only gets to pay 10% of 5000.

Use a fraction or mixed number to represent the time on a number line. Let 0 represent noon.
8:30 A.M.
Answers
The time 8:30AM is 3 and half hours before noon.
The fraction that represents 8:30AM is -3 1/2
How to represent the time as fraction?The time is given as:
Time = 8:30 A.M
Given that Noon is represented by 0.
It means that time before noon would be represented with negative value
8:30AM is 3 and half hours before noon.
So, we have:
8:30AM = -3 1/2
