Step-by-step explanation:
Draw a picture of the tetrahedron. Pick a point K on the line AB, then draw a triangular plane connecting the points K, C, and D.
The intersection of plane KCD and plane ABC is the line KC.
The intersection of plane KCD and plane ABD is the line KD.
The intersection of plane KCD and plane ACD is the line CD.
The intersection of plane KCD and plane BCD is the line CD.
Answer:
The second beach has a higher chance of being dry.
Step-by-step explanation:
At the first beach, it rained 5 out of 30 days. 5 over 30 is 1/6. 10% which is the second beach's rain rate is equivalent to 1/10. since 1/6 is greater than 1/10, the second beach will have a lower rain rate.
Answer:
1. a. 2,000
2. b. 10 years
3. a. 6.72937
4. d. 9%
Step-by-step explanation:
1. If 58% are boys, the percentage of girls is:
= 100 - 58
= 42%
That means 840 is 42% of the students in class. The students in class are therefore:
= 840 / 42%
= 2,000 students
2. If Birr 300 is invested at 6% per year, the amount in interest it earns per year is:
= 300 * 6%
= Birr 18
To get to Birr 180, it would take:
= 180/18
= 10 years
3. When a number is in percentage that means that it is a fraction with the denominator being 100. The number is decimal will therefore be it divided by 100:
= 672.937/100
= 6.72937
4. The investment accrued Birr 12 out of Birr 400 in 4 months. This means that it increased by:
= 12/400
= 3%
A year can be divided into three by 4 months. This means that the yearly rate is therefore:
= 3% * 3
= 9%
