The correct answer should be 192.
3(8)^2=3x64
Answer:
1. DB = 10 as diagonals of isosceles trapezoid are congruent
2. ∠DAB and ∠BCD are supplementary angles
- m∠BCD = 180° - 120° = 60°
3. ∠BCD is congruent with ∠ADC as trapezoid is isosceles
4. AB = 15, DC = 25,
- EB = 1/2(AB + DC) as midline
- EB = 1/2(15 + 25) = 20
5. m∠ADC = 2x - 10, m∠ABC = 3x + 40
<u>These are supplementary, find x first:</u>
- 2x - 10 + 3x + 40 = 180
- 5x + 30 = 180
- 5x = 150
- x = 30
- m∠BCD = m∠ADC = 2*30 - 10 = 50°
p(event) = (number of ways desired outcome can happen)/(total number of outcomes)
The total number of outcomes is based on drawing any marble of any color. It is the the total number of marbles which is 5 + 24 + 12 + 18 = 59.
The desired outcome is to draw a green marble. Since there are 24 green marbles, the number of desired outcomes is 24.
p(green) = 24/59
p(green) = 0.406779...
Answer: 0.41
Answer:
14
Step-by-step explanation:
to find area, use the equation A=ab/2
a and b are the sides given. a=7, b=4
next, plug into equation
A=7×4/2
A=14
