Answer: 10
The arc length of the semicircle is
a+(a+1)+(a+2)+(a+3)+(a+4)=5a+10
As x = 42, this means a+4 is 42/180 of the arc length of the circle, 5a+10.
So,
(42/180)(5a+10)=a+4
42(5a+10)=180(a+4) [multiply both sides by 180]
210a+420=180a+720 [distributive property]
30a+420=720 [subtract 180a from both sides]
30a=300 [subtract 420 from both sides]
a=10 [divide both sides by 30]

What is the equation of the line that passes through the point (8,4) and has an undefined slope?
Answers
Answer:
x = 8
Step-by-step explanation:
An undefined slope indicates that the line is vertical and parallel to the y- axis with equation
x = c ( c is the value of the x- coordinates the line passes through )
the line passes through (8, 4 ) with x- coordinate 8 , then
x = 8 ← equation of line

Find x.
x + 30
3x-30
Answers
The bases of the trapezoid are parallel and the legs are congruent, which means the interior angles are congruent as well.
An equation can be set up where x+30 = 3x-30.
Add 30 to both sides (from right to left side); Subtract x from both sides (from left to right side).
60=2x
Divide both sides by 2 and:

Which term describes the point where the perpendicular bisectors of the three sides of a triangle intersect? OA. Incenter OB. Centroid OC. Circumcenter D. Orthocenter
Answers
Answer: Circumcenter (choice C)
Explanation:
The circumcenter is useful to form a circle that passes through all three points of a triangle. It is the smallest circle possible that doesn't go inside the triangle.
The incenter is formed by intersecting at least two angle bisectors, which means we can rule out choice A. The centroid is the result of intersecting two or more medians, which allows us to cross off choice B. Choice D is out because the orthocenter is the intersection of the altitudes.

find the smallest 4 digit number which is exactly divisible by 72 and 108
with explaination
Answers
The smallest 4-digit number which is exactly divisible by 72 and 108 is 1080.
What is LCM?The least common multiple that is divisible by both a and b is the smallest positive integer, lowest common multiple, or smallest common multiple of two numbers a and b, generally indicated by LCM.
The Least common multiple of both the numbers 72 and 108 is 216. Since 216 is the least common multiple of both the numbers. Therefore, the four-digit number needs to be a multiple of 216 to be divisible by both the numbers. Thus, when 216 is multiplied by 5 the result is 1080, which is divisible by both 72 and 108. Hence, the smallest 4-digit number which is exactly divisible by 72 and 108 is 1080.

Answer:
angle s = 22
angle r = 117
angle q = 41
Step-by-step explanation:
so all of the angles equal to 180 degrees in a triangle
so you add all of t he angles like this:
x+5x+7x+2x-3=180
collect all of the like terms,
8x + 4 = 180
subtract 4 from both sides, which leaves you with 8x = 176
divide both sides by 8 leaving x on its own.
x = 22
angle s = 22
angle r = (5x22)+7 which is 117
angles q = (2x22)-3 which is 41

[tex]-\dfrac{3}{2}[/tex]
Step-by-step explanation:
Given expression:
[tex]\dfrac{\dfrac{1}{2}}{-\dfrac{2}{5}}+\left(-\dfrac{1}{4}\right)[/tex]
To divide fractions, flip the second fraction (make the numerator the denominator, and the denominator the numerator) then multiply it by the first fraction:
[tex]\implies \dfrac{1}{2} \times -\dfrac{5}{2}+\left(-\dfrac{1}{4}\right)[/tex]
To multiply the fractions, multiply the numerators and multiply the denominators:
[tex]\implies \dfrac{1 \times (-5)}{2 \times 2} +\left(-\dfrac{1}{4}\right)[/tex]
[tex]\implies -\dfrac{5}{4} +\left(-\dfrac{1}{4}\right)[/tex]
Apply the rule -a + (-b) = -a - b :
[tex]\implies -\dfrac{5}{4} -\dfrac{1}{4}[/tex]
As the denominators are the same, subtract the numerators and put the answer over the same denominator:
[tex]\implies \dfrac{-5-1}{4}[/tex]
[tex]\implies -\dfrac{6}{4}[/tex]
Simplify by dividing the numerator and denominator by the highest common factor:

3rd year 603.6589415506$(+4 quarters)
3rd year and 1 quarter 639.8784780436$
Answer:
So the second option is the answer: Makayla invests her money 2 years longer.
Step-by-step explanation:
Formula for compound interest: [tex]A=P(1+\frac{r}{n})^{nt}[/tex]
Calvin:
[tex]A=658.80[/tex]
[tex]P=400[/tex]
[tex]r=0.05[/tex]
[tex]n=12[/tex]
[tex]t=?[/tex]
Makayla:
[tex]A=613.04[/tex]
[tex]P=300[/tex]
[tex]r=0.06[/tex]
[tex]n=4[/tex]
[tex]t=?[/tex]
Lets solve for [tex]t[/tex].
1) Divide both sides of the equation by [tex]P[/tex].
[tex]\frac{A}{P} =(1+\frac{r}{n})^{nt}[/tex]
2) Take the natural log of both sides.
[tex]ln(\frac{A}{P}) =ln((1+\frac{r}{n})^{nt})[/tex]
3) Rewrite the right side of the equation using properties of exponents.
[tex]ln(\frac{A}{P}) =nt*ln(1+\frac{r}{n})[/tex]
4) Divide each side of the equation by [tex]n*ln(1+\frac{r}{n})[/tex]
[tex]\frac{nt*ln(1+\frac{r}n)}{n*ln(1+\frac{r}n)}=\frac{ln(\frac{A}{P})}{n*ln(1+\frac{r}n)}[/tex]
5) Cancel the common factor [tex]n[/tex] on the left side of the equation.
[tex]\frac{t*ln(1+\frac{r}n)}{ln(1+\frac{r}n)}=\frac{ln(\frac{A}{P})}{n*ln(1+\frac{r}n)}[/tex]
6) Cancel the common factor of [tex]ln(1+\frac{r}{n})[/tex].
[tex]t=\frac{ln(\frac{A}{P)}}{n*ln(1+\frac{r}{n})}[/tex]
Now we have an equation for [tex]t[/tex] that we can use to answer your question.
For Calvin:
[tex]t=\frac{ln(\frac{658.80}{400)}}{12*ln(1+\frac{0.05}{12})}[/tex]
[tex]t=10[/tex]
For Makayla:
[tex]t=\frac{ln(\frac{613.04}{300)}}{3*ln(1+\frac{0.06}{3})}[/tex]
[tex]t=12[/tex]
So the second option is the answer: Makayla invests her money 2 years longer.
