The sum of two numbers is 15.

Mathematics
1 answer:
Furkat [3]4 years ago
8 0
X + y = 15
x - y =3

First you have to work out what two numbers add together to make 15, for example 1 and 14 or 5 and 10. 
Then you have to work out which set of numbers have a difference of 3.
The numbers would be 6 and 9.

Once you have the two numbers, multiply them together:
6 x 9 = 54

You are going on a field trip in a school bus. A special detector placed on one of the bus's tires counts the number of rotation
Akimi4 [234]
The way tires on wheels work is that when the wheel turns one complete
turn, it moves (forward or backward) by a distance that's the circumference
of the tire.

Now, we know that the circumference of a circle is (π) times the diameter.
The diameter of the tire on this bus is 1 meter.  So its circumference is
(π · 1 meter), and every time it turns once, the bus moves 1 meter down
the road.

If the tire rotated 8,000 times, then the bus moved 8,000π meters,
or 8π kilometers.

THAT's the exact answer.  If you want to know how far that actually is,
then you take some number that's approximately π and multiply it by
8 km.  You can never get an exact answer like that, because you can
never write the exact value of π with digits.

In school, we often use  ' 3.14 ' for π .  If you do that, then the bus
traveled

                   (8 km) x (3.14)  =  25.1 kilometers .

When you do that, you have to remember that it's approximate.
If you want an exact answer, then you have to leave π in the answer.

The circumference of a circular field is 216.66 yards. What is the diameter of the field? Use 3.14 for it and do not round your
Levart [38]

Answer:

69 yards

Step-by-step explanation:

The circumference is  =\pi D

The diameter is  \frac{C}{\pi }

\frac{216.66}{3.14}=69yds

If the diameter is 69 then then the radius is 34.5

r= \frac{d}{2} \\or\\r= d*\frac{1}{2}

Hope this helps you!

Have a nice day!
