Answer:
Unitary cost= $37.34 = $37
Step-by-step explanation:
Giving the following information:
Number of tires= 8
Total cost= $298.75
<u>To calculate the unitary value of each tire, we need to use the following formula:</u>
Unitary cost= total cost / number of tires
Unitary cost= 298.75 / 8
Unitary cost= $37.34 = $37
The diagonal of a rhombus divides it into two congruent isosceles triangles.
So ∠CBD ≅ ∠CDB
∠CBD + ∠CDB + 68 = 180
2∠CBD = 180 - 68 = 112
∠CBD = 56
We also have
∠BDE + ∠E + ∠DBE = 180
∠DBE = 180 - 73 - 36 = 71
∠EBC = ∠EBD - ∠CBD = 71 - 56 = 15
Answer: ∠EBC = 15 degrees

Step-by-step explanation:
<u>Step 1: Define Equation</u>
m - 4m = -6
<u>Step 2: Solve for </u><em><u>m</u></em>
- Combine like terms: -3m = -6
- Divide -3 on both sides: m = 2
<u>Step 3: Check</u>
<em>Plug in m into the original equation to verify it's a solution.</em>
- Substitute in <em>m</em>: 2 - 4(2) = -6
- Multiply: 2 - 8 = -6
- Subtract: -6 = -6
Here we see that -6 does indeed equal -6.
∴ m = 2 is the solution to the equation.
Total paintings = 6
Number of different places for each painting = 6
Total number of ways she could hang all the painting = 6 × 6 = 36
Answer: The length is 20.
Step-by-step explanation:
If UW is the line segment, then the length of VW and UV has to equal to the length of UW
VW = 6
UV = 14
6 + 14 = 20
