Answer:
3, 15 and 30
Step-by-step explanation:
Let the first number be x
Second number is 5 times the first number = 5x
Third number is twice the second number = 2×5x = 10x
The equation becomes;
x + 5x + 10x = 48
16x = 48
x = 48 ÷ 16
x = 3
Therefore the three numbers are x = 3, 5x = 15 and 10x = 30
Answer:
=4/3 or 1 and 1/3
If it is not provided in the answer then put no solution.
Step-by-step explanation:
Answer: the correct options are B, D and F
Step-by-step explanation:
The equation of a straight line can be represented in the slope-intercept form, y = mx + c
Where c = intercept
m = slope = rate of change
Looking at the equations given, the three that apply are
B) slope = 7
y intercept = 4
It has a greater rate of change than a linear function with a slope of 6 and a y–intercept of 3
D) y = 9x + 1
slope = 9
y intercept = 1
It has a greater rate of change than a linear function with a slope of 6 and a y–intercept of 3
F) y = 8x + 5
slope = 8
y intercept = 5
It has a greater rate of change than a linear function with a slope of 6 and a y–intercept of 3
Answer:

Step-by-step explanation:
Given

Use the expression to prove a trigonometry identity
The given expression is not complete until it is written as:

Going by the Pythagoras theorem, we can assume the following.
- a = Opposite
- b = Adjacent
- r = Hypothenuse
So, we have:


Having said that:
The expression can be further simplified as:

Substitute values for sin and cos
becomes

Answer:
12566.37061435917
or
4000π
Step-by-step explanation:
the equation is 50π×80
this is because you have to find the area of the circle which is diameter times pi and then you multiply that by the height of the cylinder
