What is Area?Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. The area of a plane figure is the area that its perimeter encloses. The quantity of unit squares whcihh cover a closed figure's surface is its area.
We have, Radius of semicircle = 2 in
So, Area of semicircle = πr²/2
= 3.14/2 x 2/2 x 2 /2
= 1.57 x 1 x 1
= 1.57 mm²
So, the area of the semicircle is 1.57 mm².
Therefore, Radius = 1 in

Ms lee is handing out wristbands as students enter the dance. There are 40 black , 20 yellow, 25 orange, and 15 purple wristbands, what is the probability that Melanie will get an orange wristband?
Answer:
[tex] p =\frac{25}{40+20+25+15}= \frac{25}{100}= 0.25[/tex]
So then the probability for this case would be 0.25 or 25%
Step-by-step explanation:
For this case we have 40 black , 20 yellow, 25 orange, and 15 purple wristbands
And we want to find the probability that Melanie will select an orange wristband so we can use the definition of probability:
[tex] p =\frac{successes}{total}[/tex]
And replacing we got:
[tex] p =\frac{25}{40+20+25+15}= \frac{25}{100}= 0.25[/tex]
So then the probability for this case would be 0.25 or 25%

Answer:
A
Step-by-step explanation:
These two coordinates in (x,y) form have the same value for x, so they only differ in the y-value. That means if we subtract the y-values, that’s the vertical distance!

Evaluate the expression.
-66/(-3) + (-4) - (-5)
Answer:
23
Step-by-step explanation:
Simplify the following:
(-66)/(-3) - 4 - -5
The gcd of -66 and -3 is -3, so (-66)/(-3) = (-3×22)/(-3×1) = (-3)/(-3)×22 = 22:
22 - 4 - -5
-(-5) = 5:
22 - 4 + 5
22 + 5 = 27:

D. Toss a coin twice. If it comes up heads 2 times, pick Bella. If it
comes up heads 1 time, choose Chrissie. If it comes up heads 0
times, choose Destiny.
SUBMIT
Answer:
D?
Step-by-step explanation:
As per probability, the fair way to pick one of three students is to roll a number cube. If 1 or 6 comes up, pick Bella. If 2 or 5 comes up, pick Chrissie. If any other number comes up, pick Destiny.
What is probability?Probability indicates the chance of happening an event or incident.
For option-A, the probability to pick any one student is not equal for all of them.
For option-B, the probability of the tallest student is more to be picked.
For option-C, the probability for all the students to be picked are equal.
For option-D, the probability to pick any one student is not equal for all of them.
Therefore, option-C is the fair way to do.

find the missing letter which is N.the length is 25 in and the perimeter is 86 in
Answer:
Step-by-step explanation:
length = 25 in
Perimeter = 86 in
2*(length + width) = 86
2*(25 + N) = 86
Divide both sides by 2
25 + N = 86/2
25 + N = 43
Subtract 25 from both sides
25 + N - 25 = 43 - 25
N = 18

Which equation represents a nonproptional relationship
14)
Write an equation of the line that is perpendicular to the line y = 4x - 10 that passes through the point (-16, 2).
A)
y = - 3x - 2
y = -4x+6
y=-3x+2
y = 4x + 2
Answer:
y = -1/4x -2
Step-by-step explanation:
the perpendicular slope would be -1/4
2 = -1/4 (-16) + b
b = -2
the equation should be y = -1/4x -2

Which of the following equations have infinitely many solutions?
Choose all answers that apply:
46x - 23 = 46x + 23
-46x + 23 = 46x + 23
46x + 23 = 46x +23
-46x - 23 = 46x + 23
Answer:
46x + 23 = 46x +23
Step-by-step explanation:
46x - 23 = 46x + 23
Subtract 46x from each side
-23 = 23
This is not true so there are no solutions
-46x + 23 = 46x + 23
Add 46x to each side
23 = 96x +23
Subtract 23 from each side
0 = 96x
x=0 one solution
46x + 23 = 46x +23
Subtract 46x from each side
23 = 23
This is always true so there are infinite solutions
-46x - 23 = 46x + 23
add 46x to each side
-23 = 96x +23
subtract 23 from each side
-46 = 96x
x = -1/2
