Answer:
<h2>
C = 113.04 m</h2><h2>
</h2>
Step-by-step explanation:
circumference of a circle = 2πr
where
radius (r) = 18m
π = 3.14
plugin values into the formula
C = 2 (3.14) 18
C = 113.04 m
Answer:
<h3>No, they are not equivalent</h3>
Step-by-step explanation:
Are the following systems equivalent? How do you know?
For the equation;
2x+y= -4 ... 1
7x+7y=0 ... 2
Let us find the solution of the equation;
From 1;
y = 4 - 2x
Susbtitutw into 2;
7x + 7(4-2x) = 0
7x + 28 - 14x = 0
-7x + 28 = 0
7x = 28
x = 28/7
x = 4
Recall that y = 4-2x
y = 4 - 2(4)
y = 4 - 8
y = -4
The solution is (4, -4)
For the other equations;
5x+6y= 4 ... 1 * 1
4x+2y= -4 ..... 2 * 3
___________________
5x+6y= 4
12x+6y= -12
Subtract
5x-12x = 4 + 12
-7x = 16
x = -16/7
Since the solutions to both simultaneous equations are different, hence the systems of equations are not equivalent.
Answer:
- 10/10 on two tracks ⇒ 1/2 + 5/10
- 10/10 on three tracks ⇒ 1/2 + 1/10 + 4/10
- 10/10 on four tracks ⇒ 3/10 + 2/10 + 1/10 + 4/10
Step-by-step explanation:
As 10/10 is the fraction card. We can move it in many ways.
- 10/10 on two tracks ⇒ 1/2 + 5/10
- 10/10 on three tracks ⇒ 1/2 + 1/10 + 4/10
- 10/10 on four tracks ⇒ 3/10 + 2/10 + 1/10 + 4/10
Verification:
- 10/10 on two tracks ⇒ 1/2 + 5/10
As LCM is 10
<em>10/10 on two tracks ⇒ 1/2 + 5/10 = </em><em>(5 + 5)/10 = 10/10</em>
- 10/10 on three tracks ⇒ 1/2 + 1/10 + 4/10
As LCM is 10
10/10 on three tracks ⇒ 1/2 + 1/10 + 4/10 ⇒ (5 + 1 + 4)/10 = 10/10
- 10/10 on four tracks ⇒ 3/10 + 2/10 + 1/10 + 4/10
As LCM is 10
10/10 on 4 tracks ⇒ 3/10 + 2/10 + 1/10 + 4/10 ⇒ (3 + 2 + 1 + 4)/10 = 10/10

same as before, we look at the denominators, hmmm do a quick prime factoring.
3 = 3 * 1
9 = 3 * 3 * 1
since 9 already contains 3 and 1, we can us that
