Answer:
Statement C is not true.
Step-by-step explanation:
In the construction work sketch
A. the distance of the ground level to the pipe level is 2.5 feet. We can assume that this statement is true as we do not have the drawing.
B. The distance of the pipe level to the rope is 1 foot. Again we can assume that this statement is true as we do not have the drawing.
C. The distance between the ground level to the rope is 5 feet. Here we have to consider this statement as false if we assume statements A and B are true.
This distance will be (1+2.5) =3.5 feet.
D. The distance from the ground level to the pipe level is 1 foot less than the distance from the ground level to the rope. This statement is again true if we consider statements A and B are true.
Therefore, statement C is not true. (Answer)
Speed can be defined as the <em><u>distance covered per time. </u></em>
The average speed formula is given as: Distance/Time
The average speed of Samuel's morning training is 7 2/3 miles/hour
We are to calculate the time in hours. Remember conversion rate :
60 minutes = 1 hour
He did 3 activities every morning
- a) Ran for 30 minutes, covering 4.5 miles.
60 minutes = 1 hour
30 minutes = ?
Cross Multiply = 30 minutes x 1 hour / 60 minutes
= 0.5 hour
Hence: Speed = 4.5 miles/0.5 hour
= 9 miles/hour
- b) Swam for 20 minutes, covering 2/3 miles
60 minutes = 1 hour
20 minutes = ?
Cross Multiply = 20 minutes x 1 hour / 60 minutes
= 1/3 hour
Hence: Speed = 2/3 miles/ 1/3 hour
= 2/3 x 3/1 (miles/hour)
= 2 miles/hour
- c) Biked for 45 min, covering 9 miles.
60 minutes = 1 hour
45 minutes = ?
Cross Multiply = 45 minutes x 1 hour / 60 minutes
= 3/4 hour
Hence: Speed = 9 miles/ 3/4 hour
= 9 x 4/3 (miles/hour)
= 12 miles/hour
- Samuel's average speed during his morning training is calculated as:
(9 + 2 + 12) miles/hour / 3
= 23/3
= 7 2/3 miles/hour

The distance from the base of the ramp to the base of the sofa rounded to the nearest tenth is 47.3 inches.
<u><em>Explanation</em></u>
According to the diagram, length of the ramp is, 
inches. The top of the seat cushion is 28 inches above the floor. That means, 
inches
We need to find the distance from the base of the ramp to the base of the sofa which is 
In right angle triangle 
, using Pythagorean theorem...
So, the distance from the base of the ramp to the base of the sofa rounded to the nearest tenth is 47.3 inches.
Answer: X = (
, 6)
Step-by-step explanation:
x(4x - 19) = 30
4x^2 - 19x = 30
4x^2 - 19x - 30 = 0
ax^2 + bx + c = 0
= 
= 6
=
= 
= -1.25
X = (, 6)
