Because you can’t divide something by zero!
Hope this helps!
8 I believe if not use the app so socratic
<h3>Answer:</h3>
90
<h3>Explanation:</h3>
When p increases by a factor of 15/8, then x will, too. That is the meaning of "varies directly."
... x = (15/8)·48 = 90
First:
a. ratio of the diameter to the radius
the ratio of the diameter to the radius for any circle is always going to be 2:1 because the diameter is 2 times the legnth of the radius any time so A is not the right answer
b. the degrees of the circle is always 360, the circumference is the distance around the circle, so that would be a good indicator since 360 is constant, but the circumference can change, and if they are the same, then the circles are similar. so B is the right answer
c. Ratio of area to circumference. area=pir^2, and circumference=2pir
this is a good indicator becuase the ratio of the area and the circumference is different for every circle so c is the right answer
D. the ratio of the diameter to the circumference diameter=2r circumference=2pir
circumference=pi time diameter so the ratio of the diameter is 1:pi
this is not a good indicator so this is not the right answer
The answers are B and D, but if the teacher asks for only one, then I would pick c
Answer:
8
Step-by-step explanation:
Let s represent the length of the shorter base and height. Then (3/2)s is the length of the longer base.
The area formula for a trapezoid is ...
A = 1/2(b1 +b2)h
Filling in the given values, we have ...
80 = (1/2)(s +3/2s)s = 5/4s²
64 = s² . . . . . . . . . . . . . . . . . . . multiply by 4/5
8 = s . . . . . . . . . . . . . . . . . . . . . take the square root
The length of the shorter side is 8.
