Answer: 3
Explanation:
It is useful to summarise the information in the form of a table with columns for distance, speed and time.
Remember if you know two of these, you can write an expression or answer for the third one.
s = d/t and t = d/s and d = s × t
We have that the speed on Monday was x miles per hour and the time, 1/2 an hour. We can find the distance as x × 1/2
Show this on the table and then complete it for Tuesday as well.
Distance Speed Time
−−−−−−−−−−−−−−−−−−−−−−−−
Monday 1/2 x x 1/2
Tuesday 1/2 x (x-2) 3/4
The speed on Tuesday can be given in two ways:
It is the same as on Monday (1/2 x) or as s × t
Form an equation: 3/4 (x-2) = 1/2 x
4 x 3/4 (x-2) = 4 x 1/2 x ← x 4
3 (x-2) = 2x
3x - 6 = 2x
x = 6 ← this was the speed on Monday.
The distance run on Monday was 1/2 x 6 = 3 miles
Answer:
<u>84 students </u>
Step-by-step explanation:
See the attached table
As shown there are 20 students from Math club, 7 of them would like to choose calculators.
so, the probability of students who choose calculators = 7/20
If there are 240 students in the Math club
So, the number of students expected to choose calculators = 240 * 7/20
<u>So, the number of students = 84 students </u>

<h3>What is the area?</h3>
The area of a two-dimensional region, form, or planar lamina in the plane is the quantity that represents its extent. On the two-dimensional surface of a three-dimensional object, the surface area is its counterpart.
The composite figure can be broken down into four parts a square(A), a triangle(B) and two rectangles(C and D).
Now, if the area of the composite figure is taken out it will be,
Thus, the area of the composite figure is 264 cm².
