Let x + 15 = total penguins
15/ (x +15) = .30
15 = .30x + 4.5
.30x = 10.5
x = 35
Total penguins = 15 + 35 = 50
Double Check
15 / 50 * 100 = 30% Correct!!!
Answer:Given a rectangle, the general equation for the perimeter is P=2l+2w and area is A=lw where l is the length and w is the width.
Let x = width and x+10 = length
So the equation to solve becomes 40=2x+2(x+10) so x=5 thus the width is 5m and the length is 15m.
Thus the area is 5⋅15=75m2
Step-by-step explanation:
If this was a triangle, the answer would be 35 degrees. Can you plz show a graph if you have one though?
Line CB touches circle A only at one point (point B), hence CB is a tangent.
<h3>What is a
circle?</h3>
A circle is the locus of a point such that its distance from a fixed point (center) is always constant.
When a line intersects a circle in exactly one point the line is said to be tangent to the circle
Hence since Line CB touches circle A only at one point (point B), hence CB is a tangent.
