If you use fractions, the answer you get will always be an exact answer in the form of a fraction. resorting to decimals means that you may run into rounding errors and therefore get only an approximate answer. e.g. the fraction 1/3 cannot be exactly represented by a decimal.fractions can be easier to represent the number rather then using decimals which involve writing out many numbers it does not affect the accuracy of the answer UNLESS you are rounding up and down the numbers
You could expect about 1,248 students to play at least 4 hours every week.
Our tables have 100 students involved. All but 4 of the students are in the category of at least 4 hours. That is 96%.
Therefore, we simply need to multiply 0.96 by 1300 to get the estimated amount.
0.96 x 1300 = 1248
Answer:
see explanation
Step-by-step explanation:
(a)
The shaded figure is a trapezium with area (A)
A = 0.5 h(a + b)
where h is the perpendicular height and a, b the parallel sides, thus
A = 0.5 × 10 × (8 + 14) = 5 × 22 = 110 cm²
(b)
The volume (V) of the prism is calculated as
V = area of end face × depth
= 110 × 3 = 330 cm³
At x = 8, y = 4
At x = 14, y = 7
At y = 3, x = 6
Solution:
Given rule:
At x = 8,
Hence at x = 8, y = 4.
At x = 14.
Hence at x = 14, y = 7.
At y = 3
Multiply by 2 on both sides.
Hence at y = 3, x = 6.
