The perimeter of the semicircular region is the circumference of the semicircle plus the diameter
Formula for circumference of a semicircle --> [tex]\frac{1}{2} \pi d = \pi r[/tex]d: diameter length
r: radius length
6. [tex]Perimeter=\frac{1}{2}\pi d + d= \frac{1}{2} \pi *18+18=9\pi +18 = 46.26cm[/tex]
7. [tex]Perimeter =\frac{1}{2}\pi d+d= \frac{1}{2} \pi *20+20 = 31.4+20=51.4 in[/tex]
8. [tex]Perimeter=\pi r+2r = \pi *4 + 8=20.56mm[/tex]

Answers
Answer: 2.64
79 + 80 + 82 + 84 + 87 = 412
412/5 = 82.4
|79 - 82.4| = 3.4
|80 - 82.4| = 2.4
|82 - 82.4| = 0.4
|84 - 82.4| = 2.4
|87 - 82.4| = 4.6
3.4 + 2.4 + 0.4 + 2.4 + 4.6 = 13.2
13.2/5 = 2.64

(1/6) of 18
= (1/6)×18
= 3
18-3
=15
Answer:
15
Step-by-step explanation:
We have been told:
Alex made 18 free throws Quinn made 1/6 less than thatTherefore, to find the number of throws Quinn made, we need to find 1/6 of 18, then subtract this from 18 (the number of throws Alex made).
[tex]\begin{aligned}\sf \dfrac16\:of\:18 &=\sf \dfrac16 \times 18\\\\ & = \sf \dfrac{1 \times 18}{6}\\\\ & = \sf\dfrac{18}{6}\\\\ & =\sf18 \div 6\\\\ & =\sf3\end{aligned}[/tex]
Now we have calculated 1/6 of 18, we can subtract it from 18 to find the number of throws Quinn made:
⇒ Number of throws Quinn made = 18 - 3 = 15

Vincent plans to save of ⅔ his earnings each week for 16 weeks. He earns approximately $180 per week. About how much will Vincent have saved from earnings at the end of 12 weeks?
Please no links
Answers
Answer:
$1440
Step-by-step explanation:
2/3 earings each week
He gets approximately 180 per week
2/3 of 180 is 120
120*12=1440
He would have saved $1440.
To get 2/3 of $180, you’ll do
$60x2=$120 which is 2/3 of $180
Now, $120x12weeks= $1,440
Answer- Vincent will have $1,440 at the end of 12 weeks.

which is largest 3.3 times 10^5 or 3.1 times 10^5
Answers
Answer: 3.3 times 10^5 is bigger
Step-by-step explanation: 10^5= 10*10*10*10*10=100,000.
so 100,000 multiplied by 3.3 = 330,000
or 3.1 multiplied by 100,000 = 310,000 so it's obvious that 330,000 is bigger.

Area of rectangle is base times height (AKA length times width or however you wish to call the dimensions).
This question is a system of equations question. We can make two equations. We know that every rectangle must have 2 "lengths" and 2 "widths" (4 sides in a rectangle). Since Maria only has 64 meters of fencing, we get the equation:
2L+2W = 64
Now we know the area enclosed must be 252 so we have:
L* W = 252
Rewriting the second equation we get:
Plug this into first equation to get:
(multiply everything by L)
Solving the quadratic tells us L can be 18 or 14. Let's consider if L is 18 first by plugging 18 back into the second equation to get 18 * W = 252 which gives us W = 14. If we do the same for when L = 14, we get that W = 18.
Now you might wonder why we have 2 possible combinations, that's because in reality, it doesn't matter which one we label as length (L) or width (W).

Graph the points and draw an aproximate line of fit that includes two of the points. Then using point-slope form find the linear equation of that line.
10-(-4)=m(-5-4) is 14=m(-9) solve for m and find the slope is aproxx -14/9 or -1.555. Then do some fancy math to find your y intercept and you come out with an aproxx line of fit of y=(-14/9)x+(20/9). Or you could plug these points into excel and have it spit out a trendline of y=(-1.26)x+(0.467)

Answer: A. 9.4 units
Step-by-step explanation:
We could use the distance formula, but this problem asks us to use the Pythagorean theorem. This means we will "create" a right triangle and solve for the hypotenuse.
[1] First, we need to draw our triangle.
-> Please see attached.
[2] Now, we will count the length of the sides for the formula.
-> Please see attached.
[3] Lastly, we can use the Pythagorean theorem to solve for the missing side which also known as the hypotenuse. In this case, it is from point R to point S
