B : the coefficient of x^2 must be positive
The coefficient of x^2 (a) can be negative as well
If you would like to know how many pints should Jake measure, you can calculate this using the following step:
1 pint ... 2 cups
x pints = ? ... 8 cups
1 * 8 = 2 * x
8 = 2 * x /2
x = 8/2 = 4 pints
The correct result would be 4 pints.
Answer:
Ratio of the volume of the triangular prism and the volume of cuboid = 3 : 20
Step-by-step explanation:
Volume of a triangular prism = Area of the triangular base × Height
= × Height
= × 9
= 90 cm³
Volume of the rectangular prism or cuboid = Length × Width × Height
= 6 × 5 × 20
= 600 cm³
Therefore, ratio of the volumes of triangular prism and cuboid =
=
= 3 : 20
Answer:
3.704 Hours
Step-by-step explanation:
This problem can be solved by using concept of relative speed. relative speed is speed of one body in comparison of other.
If two bodies are moving in same direction their relative speed is calculated by taking difference of each other speed.
If two bodies are moving in opposite direction their relative speed is calculated by taking sum of each other speed.
In the problem stated two bodies are moving in north and south direction, hence they are moving in opposite direction, thus their speed can be taken sum of individual speed.
which is
(60+65) Km/Hr = 135 km/hour
Now given in question distance between two bodies is 500 KM
and relative speed = 135 km/hour
using formula of speed distance and time
Time = distance / speed = 500/135 = 3.704 Hours
Therefore it will take 3.704 Hours for both of the trains to be 500 km apart.
