True, they exist in exactly one plane
One of the angle of the triangle is 90 degrees which means it is a right angled triangle. Two angles are same i.e 45 degrees which means the angle is an isosceles triangle.
so, x = 17 (isosceles triangle)
then use pythagoreas theorem:
and x = 17, so simplify and
so
Answer:
y=-1/4x+1
Step-by-step explanation:
Hi there!
We're given the point (-8,3) and a slope of -1/4
lines are typically written in the formula y=mx+b, where m is the slope and b is the y intercept
as we are already given the slope, we can substitute its value into the equation
substitute -1/4 as m
y=-1/4x+b
now we need to find b
as the equation passes through the point (-8,3),we can use it to solve for b
substitute -8 as x and 3 as y
3=-1/4(-8)+b
multiply
3=2+b
subtract 2 from both sides
1=b
substitute 1 as b
y=-1/4x+1
5 1/2 pages in 12 minutes.
11/2 pages in 12 minutes
How many pages in an hour?
well, an hour has 60 minutes
Let's write a proportion
11/2 / 12 = x/60
cross multiply
(11/2 * 60) = 12x
330 = 12x
divide both sides by 12
27.5 or 27 1/2 = x
27.5 pages per hour.
Hope this helps
Answer:
B. I and III
Step-by-step explanation:
I and III both have the same data:
March, 73
April 74
May 78
June 84
July 75
II has different data
March 71
April 72
May 85
June 90
July 60
Since I and III have the exact same data, choice B is the best answer
Hope this helps! :)
