Answer:
2:1
Step-by-step explanation:
2/3 of the class is girls, so that means 1/3 of the class is boys. Make the number of people in the class x. The equasion would be (2/3x)/(1/3x) This simplifies to 2:1
Answer: 6/5
Explanation:
Given: 5cm cube
This means each side is 5 cm because a cube has equal sides.
Area of a square is length times width so area of 1 side of a cube:
= 5 x 5
= 25
Surface area is the area of one side of a cube times the number of sides. Now, how many sides does a cube have? 6
= 25 x 6
= 150
Surface area of a 5cm cube = 150
Volume is length times width times height:
= 5 x 5 x 5
= 125
Ratio of surface area to volume:
= 150/125
= 6/5
It pretty much looks like a one to one function. Plot the graph then draw a horizontal line,if the line touches the graph at just one point then it is
To solve the top triangle, use the sine of 45° and find the shared side length (y):
sin(45°) = y / 12
12(sin(45°) = y
y = 8.485
(The side y is opposite of the bottom triangle's 30° angle.)
Use the tangent of 30° to find the side length of x.
tan(30°) = 8.485 / x
x(tan(30°)) = 8.485
x = 8.485 / (tan(30°))
x = 14.696
The side length of x is approximately 14.696 units.
The answer to this equation is x=5.
