Answer:
a=19.6 inches^2
Step-by-step explanation:
The area of a circle can be found using
a=πr^2
We know the radius is 2.5, so we can substitute it in for r
We can also substitute 3.14 in for π
a=(3.14)*(2.5^2)
a=(3.14)*(6.25)
a=19.625
Round to the nearest tenth
a=19.6 inches^2
A number subtracted from five is equal to negative ten
The error is not there. The error is step 4. -34 becomes positive so it is not -51 it's 17. So the answer is 40/17
Answer:
Slope <em>m</em> = 1/6
General Formulas and Concepts:
<u>Pre-Algebra</u>
<u>Algebra I</u>
Standard Form: Ax + By = C
Slope-Intercept Form: y = mx + b
- m - slope
- b - y-intercept
Step-by-step explanation:
<u>Step 1: Define</u>
x - 6y = -12
<u>Step 2: Rearrange</u>
<em>Find slope-intercept form.</em>
- Subtract <em>x</em> on both sides: -6y = -x - 12
- Divide -6 on both sides: y = 1/6x + 2
<u>Step 3: Break Function</u>
<em>Identify Parts.</em>
Slope <em>m</em> = 1/6
y-intercept <em>b </em>= 2
X 1 2 3
y 10 8 6
So find the slope m: (6-10)/(3-1) = -4/2 = -2
Going backwards when x = 0, y will be 12 (you can see this)
