2×3.5+11=18
Answer: 2 markers.
Step-by-step explanation:
1. You know that she gives 12 markers to Mr. Cooke, then the rest among is:
29 markers-12 markers=17 markers
2. She divides the rest among 5 other teachers and each one of them get the same number of markers. So, you need to divide 17 markers by 5 teachers as following:
17 markers/5=3.4 markers
3. But the number of marker each one teacher has can't be a decimal number, so this number must be: 3 markers for each teacher.
3. The number of markers that will be left over is:
17 markers-(5*3 markers)=2 markers
Answer:
90 degrees, 120 degrees and 150 degrees
Step-by-step explanation:
Given that three adjacent angles are at a point. The ratio of the measurements is 3:4:5. The angles should add to 360.
First add up all the ratio
3 + 4 + 5 = 12
For ratio 3
3/12 × 360 = 90 degree
For ratio 4
4/12 × 360 = 120 degree
For ratio 5
5/12 × 360 = 150 degree
90 + 120 + 150 = 360 degree.
The angles are therefore, 90 degrees, 120 degrees and 150 degrees
Answer:
t = 9 s
Step-by-step explanation:
A stone is thrown downward with an intitial velocity of 29.5 m/sec will travel a distance of a meters, where
We need to find when the stone will hit the ground. It means when s(t) = 0. So,
So, the stone will take 9 seconds to hit the ground. Hence, this is the required solution.
