To determine the lines that are parallel, you will need to find the missing angle length in the pairs of supplementary angles (totaling 180 degree).
180 - 114 = 66 degrees
180 - 112 = 68 degrees
Using these you can see the lines that are parallel. They have matching angle measurements.
c // f
d // e
Answer: x = - 3.5
Step-by-step explanation:
Rewrite the equation by completing the square.
4x2 + 28x + 49 = 0
Completing the square method :
Divide through by the Coefficient of x^2
x^2 + 7x + (49/4) = 0
a = 1, b = 7, c = 49/4
Move c to the right side of the equation
x^2 + 7x = - 49/4
Complete the square on the left hand side by squaring its half of the x term
(7/2)^2 = (49/4)
Add the output to both sides of the equation
x^2 + 7x + (49/4) = - (49/4) + (49/4)
(x + 7/2)^2 = 0
Square root of both sides
x + 7/2 = 0
x = - 7/2
x = - 3.5
0.024 is 2.4%
0.125 is 12.5%
0.05 is 5%
Showing the workMultiply 0.05 by 100 to convert to percent:

0.5 is 50%
Showing the work - Multiply 0.5 by 100 to convert to percent:
0.5 × 100 = 50 %
Showing the work -multiply 0.024 by 100 to convert to percent:
0.024 × 100 = 2.4 %
Answer:
Step-by-step explanation:
50,000 mm=5,000 cm=500 decimeter=50 m=5 decameter
so both are equal.
Based on the data recorded by Isabella, it can be concluded the cube is rather fair.
<h3>How many times did Isabella get each number?</h3>
Based on the data, here are the results:
- Getting a 1: 6 times
- Getting a 2: 5 times
- Getting a 3: 7 times
- Getting a 4: 5 times
- Getting a 5: 6 times
- Getting a 6: 7 times
This implies, in total Isabella got the same number between five and seven times. For example, the number 2 was obtained 5 times, but the number 3 was obtained 7 times.
<h3>What can be concluded based on the results?</h3>
Even though Isabella did not get the same number of times each number, the dice is rather fair because by rolling the dice thirty six times you will obtain the same number at least five times.
Moreover, there is not a big difference in the number of times you obtain each number.
