hi zzayn i will solve this later
Explanation:
Let's establish that x= number of polio vaccinations and y=number of measles vaccinations.
Since Dr. P gave a total of 60 VACCINATIONS, we know that x+y=60. (This is equation #1)
We also know that Dr. P gave a total of 184 DOSES of the vaccinations and that the polio vaccine has 4 doses, while the measles vaccine has 2 doses. This means that our second equation is 4x+2y=184. (This is equation #2)
You can get either variable (x or y) by itself from equation #1. I always choose x.
x+y=60
-y. -y
x=60-y
Now we can plug our x value into equation #2.
4x+2y=184
4(60-y)+2y=184
240-4y+2y=184
240-2y=184
-240 -240
-2y=-56
/-2 /-2
y=28 measles vaccines
So we know that Dr. P administered 28 measles vaccines. We need to plug our y value back into equation #1 (or, to make it easier, our switched around equation) to find the number of polio vaccines.
x=60-y
x=60-28
x=32 polio vaccines
I believe Uranium it is U in the table
Answer:
Explanation:
Given that,
The radius of a flywheel, r = 0.3 m
Angular acceleration of a flywheel, 
We need to find the magnitude of the tangential acceleration after 2.00 s of acceleration.
The relation between the tangential and angular acceleration is given by :
So, the required magnitude of tangential acceleration is .
The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite direction.
Answer:
it's the distance between objects in space
Explanation: Light travels super fast; but it still takes a long time to travel between objects in space. This is because distances between objects in space are enormous.
