Answer: 49 students
Step-by-step explanation:
2 /7 of students in a school wore shorts today. The number of students to be selected in order to get 14 students who will wear shorts to school will be:
Let the number of students that will be sampled be y. This will be:
2/7 of y = 14
2/7 × y = 14
2y/7 = 14
Cross Multiply
2y = 7 × 14
2y = 98
y = 98/2
y = 49
49 students will be selected randomly.
LCM:
10: 0,10,20,30,40,50
4: 0,4,8,12,16,20
ANSWER IS 20
LCM:
10: see above numbers
6: 0,6,12,18,24,30
ANSWER IS 30
So, 10 and 8 would be 40
Answer:
1. 25
2. 10
3. 250
Step-by-step explanation:
Distance formula :√ (x2 - x1)² + (y2 - y1)² √ ()² + ()²
1. LENGTH OF AB :
A = 15,18
B = -5,3
√ (-5 - 15)² + (3 - 18)²
= √ 400 + 225
= 25
2. LENGTH OF AD :
A = 15,18
D = 21,10
√ (21 - 15)² + (10 - 18)²
= √36 + 64
= 10
AREA :
A=w x l
10 x25 = 250
