What is the approximate area of the shaded sector?
A. 38 cm2
B. 96 cm2
C. 302 cm
D. 603 cm?
Answer:
C. [tex] 302 \: {cm}^{2} [/tex]
Step-by-step explanation:
[tex]Area \: of \: sector = \frac{ \theta}{360 \degree} \times \pi {r}^{2} \\ \\ = \frac{135 \degree}{360 \degree} \times \pi {r}^{2} \\ \\ = \frac{135 }{360 } \times 3.14 \times {(16)}^{2} \\ \\ = \frac{108,518.4 }{360 } \\ \\ = 301.44 \\ \\Area \: of \: sector \approx \: 302 \: {cm}^{2} [/tex]

Step-by-step explanation:
The letters in the word JANUARY were put in a bag and drawn randomly. What is the probability of picking an a?
Answer: 2/7
Step-by-step explanation:
There are 7 letters in January, and 2 "a"s in order to find the probability, simply take 2/7. You can either leave it in the fraction form, or use the calculator, showing you have a 0.2857% chance of picking an "a"
2/7
there are 7 letters in jAnuAry and as you can see there are 2 A's so there is a 2/7 chance which is higher of a chance than the rest of the letters which are 1/7 each so it is most likely you would draw A although I can't fully say that because there is a 5/7 chance of drawing the other letters. Another way to say it is there is a 0.28571428571% chance of drawing A but there is a 0.71428571428% chance of drawing any other letter.
Hope this helps :3

work out the circumference of a cirlce with a diameter of 1.8m
Answer:
5.56 m
Step-by-step explanation:
Circumference = 2πr
r is the radius, however the diameter is given. The radius is half the diameter. So the radius is:
1.8 ÷ 2 = 0.9
Circumference = 2 × π × 0.9
= 5.56 m ( in 3 significant figures )

Answer:
We have the value as;
8x/5
Step-by-step explanation:
Here, we want to get the breakdown of the given expression
We have (x^2 - 9) as (x-3)(x + 3)
So we have;
2x/(x + 3) * (x-3)(x+3)/5 * 4/(x-3)
= 2x * 4/5= 8x/5

Jim gives the cashier a $20 bill at the pharmacy.
Write an equation that relates the change c he gets back in dollars to the cost b, in dollars, of his purchases. Which variable represents the independent variable? How much change does he get back if his purchases total $12.83?
Answer:
b= 12.83
c= 7.17
Variable "c" is independent because it does not change. Jim receives $7.17 back.

The diameter of a circle is 0.82 inches. What is the approximate area of the circle?
Answer:
.53
Step-by-step explanation:
your diameter is .82,so divide it by two to get your radius
.82 / 2 = .41
A = [tex]\pi[/tex] r ^2
A = [tex]\pi[/tex] .41 ^2
A = .53
Answer:
0.53

write an equation of the line that passes through the point (0,3) and whose slope is 2
Answer:
y - 2x = 3
Step-by-step explanation:
Use the point-slope formula y - k = m(x - h), with h = 0, k = 3 and m = 2:
y - 3 = 2(x - 0), or
y - 3 = 2x, or
y - 2x = 3
Note that the given point, (0, 3), is the y-intercept of this line, and so we immediately know b in y = mx + b: it is 3.

PLSSS HELP MEEE DUDE HELP MEEEEEE Marshall High School’s community service club will be selling baked goods as a fundraiser. The club members plan on making cupcakes and cookies. There will be 5 cookies made for every 2 cupcakes made. The club members plan on making 280 total baked goods.
Plot the point on the coordinate plane below that represents the total number of cupcakes and the total number of cookies that the community service club members plan on making for the fundraiser.
To plot the point, click the pencil tool and select the thickest brush size.
Answer:
See Explanation
Step-by-step explanation:
Let the number of cookies be x and the number of cupcakes be y.
If the total is 280, then
[tex]5x + 2y = 280[/tex]
Subtract 5x from both sides
[tex]5x - 5x + 2y = 280 - 5x[/tex]
[tex]2y = 280 - 5x[/tex]
Make y the subject
[tex]y = 140 - \frac{5}{2}x[/tex]
See attachment for graph
Any of the following equation can be plotted on the graph (they literally represent the same thing)
[tex]5x + 2y = 280[/tex]
[tex]2y = 280 - 5x[/tex]
[tex]y = 140 - \frac{5}{2}x[/tex]
Answer:
its 200 cookies and 80 cupcakes
