So you want to find how many miles are being flown in one hour.
There are 60 minutes in one hour so you want to find how many times 15 goes into 60 so you can then multiply that by 115.
60 / 15 = 4.
Now multiply 115 by 4,
115 x 4 = 460
Therefore the plane is flying at B. 460 mph.
Hope I helped!
Answer:
4/7
Step-by-step explanation:
Since there are 7 possible outcomes because there are 7 triangles the denominator will be 7. Since there are 4 white squares the chances of landing on one is 4/7
Answer:
Answer: 105
Step-by-step explanation:
In a recent survey of 700 people, 15% said that red was their favorite colour. 105 people said read was their favorite colour.
b) -4
- 8x +4 =36
First, we subtract 4 from 36 to get 32
36-4=32
-8x=32
Since a negative times a negative equals a positive, then the answer has to be negative because 36 is positive.
32 divided by 8 = 4
B) -4
Answer:
9
Step-by-step explanation:
Compare your x2 + y2=81 to the following:
x^2 + y^2 = 81
The " ^ " symbol indicates exponentiation.
Now compare x^2 + y^2 = 81 to
x^2 + y^2 = r^2.
This is the standard equation of a circle of radius r centered at the origin, (0,0). You can see for yourself that 81 must equal r^2.
Taking the square root of 81, we get plus or minus 9.
But the radius must be positive, so we reject the -9 and take +9.
The radius is 9.
