40% of 250 is 100, meaning that if 40% of 250 students are girls, then there are 150 boys!!
250 divided by 10 is 25, so you multiply 25 by 4 to get 40%!!
Basically you have to use trigonometry to solve this. You will be using a sine ratio. Type sin-1(36/43). Use the 2nd button to do this. Your answer should be 56.84659158 but round to 57.

Answer:
= 9
Step-by-step explanation:
Note there is a common ratio r between consecutive terms of the sequence, that is
r = 18 ÷ 2 = 162 ÷ 18 = 1458 ÷ 162 = 13122 ÷ 1458 = 9
A recursive formula allows a term in the sequence to be found by multiplying the previous term by the common ratio, that is
= 9 with a₁ = 2
<em>The </em><em>slope</em><em> of the diagonal line of the </em><em>smaller triangle</em><em> is; 1/2</em>
<em>The </em><em>slope</em><em> of the diagonal line of the largest triangle is; 1/2</em>
<em>Both triangles have the </em><em>same slope</em><em> because the rate of change in y-coordinates to that of x-coordinates is the same.</em>
- We want to find slope of the triangles and in mathematics we will adopt the formula;
m = (y2 - y1)/(x2 - x1)
- This simple means change in y-coordinates divided by change in x-coordinates.
The coordinates of the smaller triangle are;
y2 = 1
y1 = 0
x2 = 2
x1 = 0
Thus, slope; m = (1 - 0)/(2 - 0) = 1/2
- For the largest triangle;
The coordinates of this larger triangle are;
y2 = 3
y1 = 1
x2 = 6
x1 = 2
Thus, slope; m = (3 - 1)/(6 - 2)
m = 2/4 = 1/2
