I think the volume of the sphere is 4 centimeters.
First thing you need to do is distributive property and that will give you
7-56-7x=-14+4x then combine like terms which will then give you
-49-7x=-14+4x Next get your letters on the left do that by subtracting 4x which will give you -49-11x=-14. After that you will add 49 to both sides which will give you
-11x= 35. Divide by -11 to get x=3.18
Answer:
(x, y) = (0, 1)
Step-by-step explanation:
For polar coordinates (r, θ), the corresponding rectangular coordinates are ...
(x, y) = (r·cos(θ), r·sin(θ))
For r=1 and θ=π/2, the rectangular coordinates are ...
(x, y) = (1·cos(π/2), 1·sin(π/2))
(x, y) = (0, 1)
Answer:
Ram: 21, Hari: 12
Step-by-step explanation:
To solve the problem, we can use the following notation. We call:
= Ram's age at present
= Hari's age at present
We know that:
- Ram is 9 years older than Hari --> mathematically, this can be written as

- Three years ago, Ram was two times as old as Hari was --> mathematically, this can be written as

where (r-3) is Ram's age 3 years ago, while (h-3) is Hari's age 3 years ago
Substituting eq.(1) into eq.(2), we find:

So, Hari's age is 12; therefore, Ram's age is
Their running paths form the legs of an isosceles right triangle. The hypotenuse of such a triangle (the distance between Steve and Scott) is √2 times the length of one leg. Each has run 10 miles in the hour since they split.
They are running at 10 miles per hour.
