Answer: <em>$131.7</em>
Step-by-step explanation:
<em>Use the equation 439(n)</em>
<em>n will be 0.30 in this case</em>
<em>now multiply them</em>
<em>439(0.30)</em>
<em>Your answer will be </em>
<em>$131.7</em>
Answer:
The sum of the marked angles = Total angles on the 4 straight lines – Sum of the interior angles of the quadrilateral. Sum of interior angles of polygon of 4 sides = (4 – 2) *1800 =3600
Hence, sum of the marked angles = 4 * 180° – 360° = 720° – 360° = 360°

Step-by-step explanation:
<u>Step 1: Define</u>
-6 = b8
<u>Step 2: Solve for </u><em><u>b</u></em>
- Rewrite: -6 = 8b
- Divide 8 on both sides: -6/8 = b
- Rewrite: b = -6/8
- [Fraction] Simplify: b = -3/4
<u>Step 3: Check</u>
<em>Plug in b into the original equation to verify it's a solution.</em>
- Substitute in <em>b</em>: -6 = (-3/4)8
- Multiply: -6 = -24/4
- Divide: -6 = -6
Here we see that -6 does indeed equal -6.
∴ b = -3/4 is the solution to the equation.
Answer:
V = 825
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
The radius is 1/2 d = 1/2 (10) =5
Using 3 for pi
V = 3 ( 5)^2 * 11
V = 825
(-4,-5) would be the answer
