I assume the radius is 6 cm.
Diameter = 2 times the radius.
D = 12 cm.
We now use C = pi•D.
C = pi•12cm
C = 12pi cm
Done!
Answer:
- v = 8
- x = -12
Step-by-step explanation:
1. I like to work with positive numbers, so the first thing I'd do is multiply the equation by -1.
2v + 7 = 23
2v = 16 . . . . . subtract 7
v = 8 . . . . . . . divide by 2
<em>Check</em>
-2(8) -7 = -23 . . . . true
___
2. (x/4) -5 = -8
x/4 = -3 . . . . . . . add 5
x = -12 . . . . . . . . multiply by 4
<em>Check</em>
(-12/4) -5 = -8 . . . . true
The unit rate is 10:1 because unit rates are out of 1
You would find that by dividing 20 and 2 by the same number to get to one for this specific problem. 20 divided by two is ten and two divided by two is one. So that is your answer for part b. I can’t draw a graph however so sorry
Answer:
g = 4+2m
Step-by-step explanation:
Grandma is 4 years older than twice mothers age
is means equals
g = 4+2m where g is grandmothers age and m is mothers age
Answer: A
Step-by-step explanation:
The first thing we need to do is to make sure our equation is in standard form. The given equation is not in standard form.
3x²-2x=0
Now that the equation is in standard form, we can find our A, B, C to see which quadratic equation is correct.
A=3
B=-2
C=0
We can automatically eliminate D because the first value is -3 when it is supposed to be -(-2). Also, the denominator is supposed to be 2a. We know that A=3. The denominator should be 2(3), not 2(-2).
Next, we can eliminate B and C. For the 4ac, we know it has to be 4(3)(0) because A=3 and C=0. B and C have given 4(3)(2) and 4(3)(1), respectively. This does not match A=3 and C=0.
Therefore, A is the correct answer.
