Answer:
Step-by-step explanation:
<u>Given</u>
- m∠ABC = x°
- m∠BCD = 25°
- m∠CDE = 55°
- m∠DEF = 3x°
Add two more parallel lines passing through points C and D.
Consider alternate interior angles formed by the four parallel lines.
<u>The angles between the two middle lines are equal to:</u>
- m∠BCD - m∠ABC = m∠CDE - m∠DEF
<u>Substitute values and solve for x:</u>
- 25 - x = 55 - 3x
- 3x - x = 55 - 25
- 2x = 30
- x = 15
m∠ABC = 15°
Answer:
8.3 x 10³
Step-by-step explanation:
8,300 can be written as
8.3 x 1000 (re-writing 1000 in terms of powers of 10, 1000 = 10³)
= 8.3 x 10³
Answer:
below 15 times
Step-by-step explanation:
If the numbers on the spinner are 1, 2, 3, 4, 5, 6 (six numbers) the even numbers are 2, 4, 6 ( three numbers) than 3 out of 6 numbers on the spinner are even.
If Jane will spin the spinner below 30 times the is expected that less than half of the time 30/2 = 15 times will be an even number.
