Answer:
Object will be at a distance of 358098.6 km from the source
Step-by-step explanation:
We have given angle = 0.0008 degree 
Radius is given = 2.50 km
Linear size of the object will be equal to diameter
So linear size = 2.5×2 = 5 km
We know that linear size 
So 
d = 358098.6 km
Answer:
The correct answer is option d. 179.503 cub in
Step-by-step explanation:
Formula:
Volume of Sphere = (4/3)πr³
r - radius of sphere
To find the volume of sphere
From the figure we get,
diameter d = 7 in
radius r = d/2 = 7/2 = 3.5 in
Volume = (4/3)πr³ = (4/3) * 3.14 * (3.5)³ = 179.503 cub in
Therefore,the correct answer is option d. 179.503 cub in
Answer:
B. 28 hours
Step-by-step explanation:
GIVEN :- <em>Time taken by family to travel 600 km is 8 hours</em>
CALCULATIONS :-
<em>To calculate the time to travel 2100 km, we need to calculate distance traveled in 1 hour</em>
<em>Distance traveled in 1 hour = 600 km ÷ 8</em>
<em> = 75 km</em>
<em>Time required to travel 2100 km = 2100 ÷ 75</em>
<em> = </em><em>28 hours</em>
Therefore time required to travel 2100 km is 28 hours.
Yes because they are all even
1 day = 1500 bricks
5 days = 1500 x 5
5 days = 7500 bricks
Answer (a) He would expect to lay 7500 bricks in a five day week.
1500 bricks = 8 hours
1 brick = 8/1500
10 000 = 8/1500 x 10 000 = 53 hours (nearest hour)
Answer: (b) It will take him 53 hours to lay 10000 bricks.
