Answer:
139 donors
Step-by-step explanation:
So we have 37:43 as ratio. Lets add 37 and 43, giving us 80. So let's make the proportion, 37/80 = d/300. (d since d it stands for donors). Now let's cross multiply. 80d = 11100
d=11100/80
d=138.75
u dont just have part of a person, as that is manslaughter, you round to 139
Answer:
What is the question?
Step-by-step explanation:
First, set it up as variables
W=x
L=2x+3
apply perimeter formula and solve
2(x+2x+3)=66
2(3x+3)=66
6x+6=66
6x=60
x=10
width=10
length=23
area= 230
The <em>correct answer</em> is:
A) A tangent is never a secant.
Explanation:
A tangent is a line that touches a circle in exactly one point. A secant is a line that touches a circle in two different points.
Since a tangent only touches once and a secant touches twice, there is no way a tangent can be a secant.
