Answer:
The number of students who were on each bus
Step-by-step explanation:
- Notice there are 70 students, and 70 is the sum of the equation
- We know 6 students weren't on either bus
- The remaining students must represented by 2b
- So if 2b is all the students who got on buses b is half that, representing each group of students per bus
Answer:
9
Step-by-step explanation:
To find the median of a set of data, arrange the data by value:
6, 7, 9, 12, 13
The number in the middle is the median.
Answer:
10!
Step-by-step explanation:
You will need to put 2 half cups to make 1.
So, 10 half cups is equal to 5 cups.
Answer:
We note that the equation that is compatible with the given equation is the kinematic equation of free fall where;
t² = 39.2 × 2/9.81
From which we have;
The time it takes the snowball to reach the ground is approximately 2.83 seconds
Step-by-step explanation:
The height of the building from which the ball is dropped, h = 39.2 m
The equation of the dropped a snowball, is given as follows;
t² = 39.2 × 9.8
Using the From the equation of free fall, we have;
s = u·t + 1/2·g·t²
Where;
u = The initial velocity = 0 m/s
t = The time of flight
g = The acceleration due to gravity = 9.81 m/s²
Therefore, we get;
∴ s = The height from which the snowball is dropped = 39.2 m
Therefore, we get;
39.2 = 0×t + 1/2×9.81×t²
∴ t² = 39.2 × 2/9.81 ≈ 7.99
t = √(7.99) ≈ 2.83
The time it takes the snowball to reach the ground, t ≈ 2.83 s.
Answer:
Jill sold more apples
1 more than Alice
Step-by-step explanation:
Jill sold 40 fruits
Alice sold 40 fruits
15% of Jill's sales is APPLES, that is:
15/100 = 0.15
0.15 * 40 = 6
Jill sold 6 apples.
Now, it is given Alice sold 5 apples.
<em>Who sold more? Of course, Jill.</em>
<em>By how much? 6 - 5 = 1 apple more</em>
