Answer:
Between 9:00 am and 10:45 am, there have been 1 hour and 45 minutes or 1.75 hours have passed. Let x be the speed of the slower cyclist and x+ 5 be the rate of the second cyclist. The given situation is best represented through the equation below,
x(1.75) + (x + 5)(1.75) = 47.25 km
The value of x from the equation is 11. Thus, the two bicyclists' rates are 11 km/h and 16 km/h.
Answer:
1: 1/3
2: 3/19
3: 7/3
Step-by-step explanation:
<u>Given</u>:
It is given that the figure of the cone.
The radius of the cone is 2.3 m.
The height of the cone is 15 m.
We need to determine the volume of the cone.
<u>Volume of the cone:</u>
The volume of the cone can be determined using the formula,

where r is the radius and h is the height of the cone.
Substituting r = 2.3 and h = 15 in the above formula, we get;




Rounding off to the nearest hundredth, we get;

Thus, the volume of the cone is 83.05 cubic meters.
As it is emphasized above, the area (A) of a square is the square of its sides (l),
A = l²
The area of the square should be 120 ft². Substituting this to the equation,
120 ft² = l²
Solving will give us an answer of l being approximately equal to 10.95 ft.
Hope i'm right
