Step-by-step explanation:
The length of the radius of the circle is 1.909.
What is circumference of circle?The circumference of a circle is the length of the boundary of the circle. If we cut open the circle and straighten it the length of the boundary will be the measure of the circumference of the circle.
The circumference of a circle is measured in units of length like meter, centimeter, etc. The formula for calculation of circumference is,
Circumference = 2πR
Where R is the radius of the circle,
π (pi) is a constant value.
The value of π = 3.1415926535897.
According to the question
Clearly the arc ACB is the half the circumference of the circle
⇒ [tex]\frac{1}{2} 2\pi r=6[/tex]
⇒ [tex]r = \frac{6}{\pi }[/tex]
⇒ r = 1.909
Hence, the length of the radius of the circle is 1.909.

Serena brought a total of 135 notebooks and pencils for her students. Each notebook cost 1.75 and each pencil cost 0.35. The total cost of her purchase was 122.85. How many pencils did Serena buy?
Answer:
81 pencils
Step-by-step explanation:
1. Set up variables
Pencils = p
notebooks= n
2. Set up a system of equations
p+n= 135 (The amount of supplies bought)
1.75n +0.35p = 122.85 (Equation for the cost)
3. Solve the system of equations (I'll use substitution)
a)p= 135-n (I just rearranged it)
1.75n + 0.35p= 122.85
b) Substitute the first equation into the second)
1.75n + 0.35(135-n) = 122.85
c) Solve!
1.75n + 47.25 - 0.35n = 122.85
1.4n = 75.6
n= 54
Serena bought 54 notebooks!
4. Substitute the number of notebooks into the first equation
p +n = 135
p + 54= 135
p = 81
Serena bought 81 pencils!!!
I hope this helps!!!!
Answer:
Serena purchased 81 pencils
Step-by-step explanation:
Let x = the number of pencils Serena bought
Let 135 - x = the number of notebooks Serena bought
1.75(135 - x) + .35x = 122.85 Multiply both sides of this equation by 100.
175(135 - x) + 35x = 12,285
23,625 - 175x + 35x = 12,285
-140x = -11,340
x = 81 pencils

A bicycle wheel has a diameter of 559 mm and has 32 equally spaced spokes. What is the approximate arc length, rounded to the nearest hundredth, between each spoke? Use 3.14 for π . Show your work.
Answer:
Arc length = 54.85mm
Step-by-step explanation:
360/32 = 11.25
11.25 * 559 = 6288.75
6288.75 * 3.14 = 19746.675
19746.675/ 360 = 54.851875
Rounded to the nearest hundredth
Arc length = 54.85mm
The length of the arc is 54.9mm
Data given;
diameter = 559mm, r = d/2 = 279.5mmnumber of spokes = 32π = 3.14To solve this question, we have to use the formula of length of an arc which is given as
L = θ/360 * 2πr
To find the angle between each spoke, let's divide 360 by 32
[tex]\theta = 360/32\\\theta = 11.25^0[/tex]
Now that we have the value of the angle, let's substitute it and solve for the length of the arc.
[tex]L_a_r_c = \theta/360 * 2\pi r\\L_a_r_c = \frac{11.25}{360} * 2 * 3.14 * 279.5\\L_a_r_c = 54.9mm[/tex]
The length of the arc is approximately 54.9mm

A girl has 11 coins in dimes and quarters. Their value is $1.55. How many quarters does she have?
8
3
5
Answer:
she has 3 quarters
Step-by-step explanation:
let's call the amount of dimes D
let's call the amount of quarters Q
you know that she has 11 coins in total,
so D + Q = 11.
you also know that each dime is worth 10 cents.
and each quarter is worth 25 cents.
so 10d + 25q = 155
this is a system of equations. solve by substitution:
d = 11 - q
10d + 25q = 155
10(11 - q) + 25q = 155
110 - 10q + 25q = 155
15q + 110 = 155
15q = 45
q = 45/15
q = 3

Aahil, James and merav share £90 in the ratio 1:3:5 how much does aahil get
Answer:
9
Step-by-step explanation:
90 x 1/9 =9
Answer:
£10
Step-by-step explanation:
With these 'sharing' ratio questions, first work out the total amount of parts in the ratio:
1:3:5 = 1 + 3 + 5 = 9 parts
Now divide the total amount of parts by the total amount of money shared :
90 / 9 = 10
Now multiply by the appropriate value, in this case, aahil.
aahils value is 1.
1 × 10 = £10
