Answer:
The answer to your question is x = 40°
Step-by-step explanation:
According to the picture we determine that the triangle to the right is isosceles so two of its angles are equal.
Remember that the sum of the internal angles in a triangle equals 180°
2x° + 100° = 180
- Subtract 100 in both sides
2x + 100 - 100 = 180 - 100
- Simplify
2x = 80
-Divide both sides by 2
2/2 x = 80/2
Simplify and result
x = 40°
Answer:
2.83 inches longer
Step-by-step explanation:
The SA of a cube is 6s^2.
Therefore the length of the side of the 1200 square inches cube is approximately 14.142 inches long.
The length of the side of the 768 square inches cube is approximately 11.314 inches long.
If you subtract those two numbers, you get the difference in the lengths which is approximately 2.83 inches.
Answer:
Step-by-step explanation:
Length of:
First piece = x
Second piece = 4x
Third piece = 5x
Equation: 30 = 4x + 5x + x
Solving the Equation:
10x = 30
x = 3
Lengths of:
First piece = 3 inches
Second piece = 12 inches
Third piece = 15 inches
Answer:
A wave period is the measure of the time it takes for the wave cycle to complete.
The period of the wave is 2 seconds.
1) 3j + 5p = 7.60 and 1j + 2p = 2.90
2) Solving for j and p
j = 2.90 - 2p
3(2.90 - 2p) + 5p = 7.60
8.7 - 6p + 5p = 7.60
8.7 - p = 7.60
-p = -1.1
p = 1.1
1j + 2(1.1) = 2.9
j + 2.2 = 2.9
j = .7
3) The values of p and q:
p = $1.1 per pancake, j = .70 cents per glass
