Answer:
5.73cm
Step-by-step explanation:
Given parameters:
Circumference of the circle = 36cm
Unknown
Length of the radius = ?
Lets represent the radius by r
Solution
The circumference of a circle is the defined as the perimeter of a circle. The formula is given as:
Circumference of a circle = 2πr
Since the unknown is r, we make it the subject of the formula:
r = 
r = 
= 
= 5.73cm
Answer:
(x, y) = (-4, 4)
Step-by-step explanation:
You find the values of x and y by working the problem using any of the methods of solving simultaneous equations that you have been taught.
Here, you observe that the y-coefficients are the same in each equation. That means you can cancel the y-terms by subtracting one equation from the other.
(7x +6y) -(4x +6y) = (-4) -(8)
3x = -12 . . . . simplify
x = -4 . . . . . . divide by 3
Now, you can substitute this into either equation to find y.
4(-4) +6y = 8
6y = 24 . . . . . . . . add 16
y = 4 . . . . . . . . divide by 6
The solution to this system of equation is ...
Answer:
Step-by-step explanation:
(i) x+2y=4
(ii) x=4-2y
(iii) 2x-2y=5
substituting (ii) in (iii)
2x-2y=5
2(4-2y)-2y=5
8-4y-2y=5
-6y=5-8
-6y=-3
(iv) y=
substituting (iv) in (ii)
x=4-2y
x=4-2×
x=4-1
x=3
∴ B.(3,)

Answer:
2
Step-by-step explanation:
The coefficient is the number attached to the variable, which in this case is 2.
The number of bags that they will need if each bag contains 500 cubic inches of confetti is 20,000
<h3>How to find the total volume ?</h3>
One bag contains 500 cubic inches of confetti.
Therefore,
1 bag = 500 inches³
The student need to fill 100 containers with the bag.
Each container can accomodates 100,000 cubic inches.
Therefore,
1 bag = 500 inches³
100,000inches³ = 1 container = 200 bags
Therefore,
100 containers will contain 20, 000 bags of confetti.
