Answer:
C. b-4
Step-by-step explanation:
The number -4 shouldn't change since she read 4 fewer books
7 out of 50 people so to find the whole amount u must multiply 50x8 to =400 and multiply 7x8 =56 therefore 56 out of 400 have traveled to a foreign country. however 56 is not MORE THAN 56. if it said 56 or more he would be correct but because he says more than 56 he is incorrect. hope that helps!
The first graph function has a constant additive rate of change of -1/4.
From the figure:
First of all when we talk about a rate of change that means a linear relation between variables, which is proper of a linear function represented by the first function showed in the image.
In the first graph we can observe that the x variable increases and y - variable decrease.
rate of change = slope = -1/4
from first graph take any two points.
(2,1) and (-2,2)
slope = 2 - 1 / -2-2
= 1/-4
= -1/4

Answer:
Radius = 11.85yd
Step-by-step explanation:
Volume of a Cone formula: V = πr²(h/3)
We know that;
V = Volume
r = radius
π = pi (this is a sign located on your calculator)
h = height
We are given that;
V = 4,410
r = unknown
h = 30
Let's substitute the values in:
=> V = πr²(h/3)
=> 4,410 = πr²(30/3)
=> 4,410 = πr²(10)
=> 4,410 / 10 = πr²
=> 441 = πr²
=> 441 / π = r²
=> 140.37 = r²
=>
= r
=> 11.85 = r
Therefore, <u>the radius of the cone = 11.85yd</u>
