Dr. Potter provides vaccinations against polio and measles.

Mathematics
1 answer:
zaharov [31]3 years ago

Answer:

28 polio vaccinations and 32 measles vacinnacions.

Step-by-step explanation:

x= polio vaccinations

y= measles vaccinations


here we have an ecuation system:

x+y=60 (vaccinations)

2x+4y=184 (doses)

In order to solve it I will solve the x in the first ecuation:

x=60-y

And replace it on the other ecuation:

2(60-y)+4y=184 -----> 120-2y+4y=184------>2y=64------->y=32

Now I replace this result in x=60-y, so x=28.

The sum of two numbers is 70. one number is 4 times as large as the other. What are the numbers?
FinnZ [79.3K]

One number is 4 times the other, so x and 4x.

The sum of two numbers is 4x+x=70.

Solve for x to get

x=70/5=14

the other number is 4x=4*14=56

A ramp slopes from a warehouse door down to the street. The height of the ramp is 5 feet, and the ramp ends 10 feet from the bas
Tomtit [17]
If you graph this, your first point will be at (0,5), as the ramp is at the warehouse door but 5 feet up. The second point is (10,0) as it is touching the ground but it's 10 feet away from the warehouse.
To find slope, you do (y2-y1)/(x2-x1).
When substituting in the variables, you get (0-5)/(10-0), which is -5/10, which is simplified to -1/2. Of course, that is when the warehouse is Quadrant II. If you look at it from another point of view, the slope will be positive so your answer is A) 1/2.
If this was unclear feel free to comment :)
