Answer:
Step-by-step explanation:
Looking at the diagram,
Line DT is parallel to line line BM, therefore, triangle DHT is similar to triangle BHM. This means that
DH/DB = TH/MH
DH = 15 + 6 = 21
TH = 9 + x
Therefore
(9 + x)/21 = 9/6
Cross multiplying, it becomes
6(9 + x) = 21 × 9 = 189
54 + 6x = 189
Subtracting 54 from the left hand side and the right hand side of the equation, it becomes
6x + 54 - 54 = 189 - 54
6x = 135
Dividing the left hand side and the right hand side of the equation by 6, it becomes
6x/6 = 135/6
x = 22.5
Divide 8 by 9
8 / 9 = 0.888
0.88 is greater than 0.60 so it is not between 0.45 - 0.60
Answer:
12709 balls
Step-by-step explanation:
Given
Dimension of Room = 15 ft by 20 ft by 10 ft
Diameter of Ball = 9.2 inches
Required
Determine the number of balls that can be occupied by the room
First, we need to calculate the volume of the room
This is done by multiplying the dimensions of the room


Next, we calculate the volume of the ball.
The ball is a sphere.
So:

Where



So:


To calculate the number of balls, we then divide the volume of the room by volume of a ball

Convert ft^3 to in^3




<em>-- approximated</em>
<em>Hence, the room will contain 12709 balls</em>

Answer:
bryan walked dogs for 5.8 hours
Step-by-step explanation:
if he had $52 and the walk per hour is $9
you have to divide 52/9
52/9 is 5.77777777777...
after you roud it to the nearest tenth that is 5.8
