i just don’t understand how to do the half circle part. so if you could just give me that number i can do the rest.
Answer:
the radius of the circle is 5 and you find the raidus of the circle by using the formula A= (pi)r squared. then you'd divide that answer by two. :)
Step-by-step explanation:
simplify each expression.

Given:
The equation is:
[tex]3^x\times 9=3^{2n-1}[/tex]
To find:
The value of n in terms of x.
Solution:
We have,
[tex]3^x\times 9=3^{2n-1}[/tex]
It can be written as
[tex]3^x\times 3^2=3^{2n-1}[/tex]
[tex]3^{x+2}=3^{2n-1}[/tex] [tex][\because a^ma^n=a^{m+n}][/tex]
On comparing the exponents, we get
[tex]x+2=2n-1[/tex]
Add 1 on both sides.
[tex]x+2+1=2n-1+1[/tex]
[tex]x+3=2n[/tex]
Divide both sides by 2.
[tex]\dfrac{x+3}{2}=n[/tex]
Therefore, the value of n is terms of x is [tex]n=\dfrac{x+3}{2}[/tex].

Step-by-step explanation:
On Monday, a museum had 350 visitors. On Tuesday, it had 680 visitors. Estimate the percent change in the number of visitors to the museum. Use pencil and paper. Estimate how many people would have to visit the museum on Wednesday to have the same estimated percent change between Tuesday and Wednesday as between Monday and Tuesday. Explain your answer.
Answer: See explanation
Step-by-step explanation:
From the question, we are informed that On Monday, a museum had 350 visitors while on Tuesday, it had 680 visitors. The percent change in the number of visitors to the museum will then be:
= (680 - 350)/350 × 100
= 330/350 × 100
= 94.29%
The number of people that'll have to visit on Wednesday to have the same estimated percent change will be:
= 680 + (94.29% × 680)
= 680 + (0.9429 × 680)
= 680 + 641
= 1321
The area of a trapezium is 300sqm and its height is 10m, if one of the parsllel sides is 10m, the length of the other parallel side is
Answer:
50M
Step-by-step explanation:
The area of a trapezium = 1/2 x ( a + b) x h
a and b are the parallel sides
h = height
300sqm = 0.5 x (10 + b) x 10
divide both sides by 10
30 = 0.5 x (10 + b)
Divide both sides by 0.5
60 = (10 + b)
b = 60 - 10 = 50

A collection of nickels and quarters is worth $2.10. There are 22 coins in all . How many of each coin
are there?
Answer:
17 nickels
5 quarters
Step-by-step explanation:
Let n = no. of nickels
22 - n = no. of quarters
Each quarter is 25 cents and each nickel is 5 cents
5n = total amount of money in cents for the nickels
25(22 - n) = total amount of money in cents for the quarters
Since the total amount of money is $2.10 or 210 cents we have the equation
5n + 25(22 - n) = 210
5n + 550 - 25n = 210
-20n + 550 = 210
-20n = -340
n = 17 nickels
22 - n = 22 - 17 = 5 quarters
Now, you don't need to do all that I did. I explained in detail what is going on in this problem. All that you would need to do is write this:
let n = no. of nickels
22 - n = no. of quarters and then write the equation and solve
5n + 25(22 - n) = 210
?? OK?

10 is 6% of what number
Answer:
166.67
Step-by-step explanation:
We have, 6% × x = 10 or, 6/100 × x = 10
Multiplying both sides by 100 and dividing both sides by 6,
we have x = 10 × 100/6
x = 166.67
If you are using a calculator, simply enter 10 × 100 ÷ 6, which will give you the answer.

180 is a straight angle and 90 is a Right angle
can someone help find x, y, and z
Answer:
Step-by-step explanation:
x^2=13^2-12^2
x^2=25
x=5
(sin90)/13=(sin(90-A))/5
sin(90-A)=5/13
90-A=arcsin(5/13)
A=90-arcsin(5/13)
tan(90-arcsin(5/13))=5/y
y=5/(tan(90-arcsin(5/13))
y=25/12
z^2=(25/12)^2+5^2
z=65/12
(x,y,z)=(5, 25/12, 65/12)

Find the value of the lettered angles in each of the following ( see image ).
Please show workings.
The only given angles are 60° , 10° , 40°
Answer:
Step-by-step explanation:
s + 40 + 60 = 180 {angle sum property}
s + 100 = 180
s = 180 - 100
s = 80
This figure is a cyclic quadrilateral. sum of opposite angles are 180
s + v + 60 + 10 = 180
80 + v + 60 + 10 = 180
v + 150 = 180
v = 180 - 150
v = 30
y+ 10 + v = 180 {angle sum property}
y + 10 + 30 = 180
y + 40 = 180
y = 180 - 40
y = 140
9514 1404 393
Answer:
r = 80°, s = 80°, t = 10°, u = 60°, v = 30°
Step-by-step explanation:
Working clockwise from the left side, we can name the points on the circle as A, B, C, D. The given inscribed angles are half the measure of the arcs they intercept, so we have ...
arc BD = 2×40° = 80°
arc DA = 2×60° = 120°
arc CD = 2×10° = 20°
From these measures, we can deduce the measures of the individual arcs as ...
arc AB = 360° -BD -DA = 360° -80° -120° = 160°
arc BC = BD -CD = 80° -20° = 60°
Then the angle measures of interest are ...
r = AB/2 = 80°
s = AB/2 = 80°
t = CD/2 = 10°
u = DA/2 = 60°
v = BC/2 = 30°
