Answer:
40 people
Step-by-step explanation:
First thing, you have to find the area below the 40 - 55 line in the histogram. The area can be find using the area of a rectangle: side × side
Doing this you'll find an area of 60.
After that, find the total area of the histogram in the same way: separate it in rectangles and use the formula for the area of a rectangle, and after you'll find a total area of 100
Now you have to do a rule of three:
We know from the question statement that the amount of people with 40 - 55 years old is 25, and that area correspond to 60, so:
60 ------- 24
100 ------- x
60•x = 24•100
60x = 2400
x = 2400/60
x = 40
Answer:
14th term of geometric sequence 7, 28, 112 is 469762048
Step-by-step explanation:
Geometric sequence : 7, 28, 112, .....
First term = a = 7
Common ratio = r =
Common ratio = r =
Formula of nth term =
Substitute n = 14
So,
Hence the 14th term of geometric sequence 7, 28, 112 is 469762048

The horizontal distance from the point where it was launched is 7.143.
We have given that,
The path of the marshmallow can be modeled by the quadratic y=−0.07x^2+x+2.2,
x represents the horizontal distance from the point it is launched, in feet.
<h3>What is the horizontal distance?</h3>
Horizontal distance means the distance between two points measured at a zero percent slope.
(1) Put x = 7.143 in given equation
y= -0.07(7.143)^2+7.143+2.2
y= 2.2
y= 5.771
We have to determine the what is its horizontal distance from the point where it was launched.
The value of x is called horizontal distance.
Therefore the horizontal distance from the point where it was launched is 7.143.

Answer:
34.6 units
Step-by-step explanation:
Given data
A (-5, -5), B (3, 4)
distance is
B (3, 4), C (3, -5)
C (3, -5), A (-5, -5)
Hence the perimeter
= 12.80+9+12.80
=34.6 units
