If the ratio of boys to girls is 11:9 and there are 124 more boys than girls:
Let's say that the number of boys is 11x and the number of girls is 9x.
So, 11x = 9x + 124
2x = 124
x = 62
The total number of students = Number of boys + number of girls
= 11x + 9x
= 20x
= 1240 students
Thus, the total number of students attending the school is 1240.
the diagonal of the triangle representa the lenght of the ladder and is 12 foot
as the Sen alpha = CO/H, OF THIS FORMULA , CO IS THE HICK OPPOSITE AND REPRESENT THE HEIGHT
CO = Sen alpha*H = Sin (60°)* 12 = 10,39 FOOT
5/18 ÷ 2/6
5/18 * 6/2
30/36
5/6
Complete question is;
Suppose that a dimension x and the area A = 2x² of a shape are differentiable functions of t. Write an equation that relates dA/dt to dx/dt.
Answer:
Step-by-step explanation:
Since A = 2x²
Let's differentiate both sides with respect to x.
dA/dx = 4x
Now, we want to find the relationship between dA/dt and dx/dt
dA/dt can be expressed as;
(dA/dt) = (dA/dx) × (dx/dt)
Thus;
dA/dt = 4x(dx/dt)
Thus, the equation that relates dA/dt to dx/dt is;
dA/dt = 4x(dx/dt)
Answer:
I would believe you are talking about the Pythagorean Theorem:
In that case the formula is <u>L^2 + L^2 = H^2.</u>
If you have the hypotenuse it is:
<u>H^2 - L^2 = L^2:</u>
When solving, just substitute your lengths for each side of the triangle.
Note: This only works with right triangles.
