Answer:
(D) 11: 00
Step-by-step explanation:
We have been given that Cassie leaves Escanaba at 8:30 AM heading for Marquette on her bike. Brian leaves Marquette at 9:00 AM heading for Escanaba on his bike.
This means that Cassie leaves 1/2 hour before Brian.
Since Cassie bikes at a uniform rate of 12 miles per hour, so distance covered in half hour would be half of 12 miles that is 6 miles.
Since total distance is 62 miles, so distance left between both at 9:00 Am would be 
.
We are told that Brian bikes at a uniform rate of 16 miles per hour and Cassie bikes at a uniform rate of 12 miles per hour, so distance traveled by both in one hour would be 
miles.
Let us divide 56 by 28 to find time taken to complete 56 miles.
.
Since it will take them 2 hours to cover 56 miles, therefore, they will meet 2 hours after 9:00 AM that is 11:00 AM.
The number of milligrams of aluminum is 400 times the number of milligrams of gold in the body.
<u><em>Explanation</em></u>
Lets assume, the number of milligrams of aluminum is 
times the number of milligrams of gold in the body.
The body of a 154 pound person contains approximately 4 × 10⁻¹ milligrams of gold and 16 × 10¹ milligrams of aluminum.
So the equation will be...
So, the number of milligrams of aluminum is 400 times the number of milligrams of gold in the body.
Answer:
The approximate area is 35 square centimeters
Step-by-step explanation:
we know that
The cross section passing through the diagonal of opposite faces of the cube is a rectangle
so
the approximate area is equal to
where
b is the diagonal of a face
h is the length side of the cube
we have
substitute
92 divided by 20884 is 0.00440528634.
Answer:
0.000008 m
Step-by-step explanation:
The diameter of a red blood cell is 
. We need to write the value in the standard notation.
means there are 5 zeros before 8. It can be written as :
So, the standard notation is 0.000008 m. Hence, the correct option is (d).
