Step-by-step explanation:
Because if one out of four is read then there is four marbles.
Q1. The answer is 100 hours
10 ml is for 1 hours
1l is for x hours
1l = 1000 ml
So, make a proportion:
10 ml is for 1 hours
1000 ml is for x
10 ml : 1h = 1000 ml : x
x = 1h * 1000 ml : 10 ml = 100 hours
Q2. The answers are:
1. kg - measurement of mass
2. cm² - measurement of area
3. L - measurement of volume (1L = 1 dm³)
4. m - measurement of length
Based on the dimensions of the wall and the triangular glass, the number of mirrors needed is 215 mirrors.
<h3>What number of mirrors are needed?</h3>
First find the area of the wall:
= 36 x 93
= 3,348 m²
The area of the triangle, assuming it is an equilateral triangle is:
= (√3/4) x 6²
= 15.59 m²
The number of mirrors needed is:
= 3,348 / 15.59
= 215 mirrors
