Answer:
The height of the cylinder is 4x units
Step-by-step explanation:
see the attached document
You add the number of places from the number to the decimal.
In this case .002 is 3 place and so is .003
The answer is .000006
Answer:
50
Step-by-step explanation:
Let x represent the number of people that attended the movie.
And y the number of adults that attended the movie
Given;
Percent of adults that attended the movie = 40%
Number of adults that attended the movie y = 20
So,
40% of those that attended the movie area adults.
y = 40% of x
y = 40/100 × x
y = 0.4x
(Ratio of y to x is 4:10 or 0.4)
Making x the subject of formula;
x = y/0.4
Substituting the value of y given;
x = 20/0.4
x = 50
Therefore, 50 people attended the movie.
2x+4y=36 legs
2 for the two legged animals and 4 for the four legged animals
There are 10 animals so insert numbers that add up to 10 in for x and y
In this case x=2 y=8
Hope this helps!
Answer:
21.3
Step-by-step explanation:
It's easier to see how to do this if you transfer the 11 to the bottom of the rectangle. The look at the left triangle. It has 3 sides.
24, 11, and a.
You should be able to find a using
a^2 + 11^2 = 24^2 Expand the squares
a^2 + 121 = 576 Subtract 121 from both sides
a^2 = 576 - 121
a^2 = 455 Take the square root of both sides.
sqrt(a^2) = sqrt(455)
a = 21.33
or
a = 21.3
