Step-by-step explanation:
The formula is<em> y=mx+b</em>, with <em>m</em> representing the slope, <em>x</em> representing the <em>x </em>coordinate, and<em> b</em> representing the y-intercept. Since -⅓ is the slope, that means that the equation starts off as y=-⅓. We know that the y-intercept is where the line meets the y-axis, so the y-intercept is 9. Since 9 (the y-intercept) is being added, that means the equation is y=-⅓+9.
Answer:
y=-⅓+9
Hey there! I'm happy to help!
To find the volume of a cone, you take the area of the base, multiply it by the height and divide it by three.
We see that the radius of our base is three. To find the area of the base, we will square the radius and multiply it by 3.14 (formula for area of circle).
3²=9
9×3.14= 28.26
We multiply it by the height.
28.26(2)=56.52
We divide it by three.
56.52/3=18.84
Therefore, the area is 18.84 units cubed.
Now you can find the volume of cones! I hope that this helps! Have a wonderful day!
Answer:
$4
Step-by-step explanation:
For this, you want to find the greatest common factor
This basically means what number can be divided out of all of these.
So, you can find the factors for all of them and find which one appears in all three numbers and which is the greatest number
for 12:
1, 2, 3, 4, 6, 12
For 20:
1, 2, 4, 5, 10, 20
For 56:
1, 2, 4, 7, 8, 14, 28, 56
The numbers that appear in all of there are:
1, 2, and 4
And since we want to find the greatest amount she can charge for bracelet, the answer is:
$4
