Answer:
NO because
Step-by-step explanation:
1/2+1/2+1/4=1 1/4
1/2=25min
25+25+12.5=62.5
It would take 62.5 min to do 1 1/4 acres
The diagonal of any square always occurs in a ratio of
relative to the square's sides. That means if
is the side length, then
gives the length of the diagonal. It follows that
.
Then the area of the square is
square inches
Answer:
obtuse, isosceles
Step-by-step explanation:
We have two angles that have the same measure - that means two sides are equal length. That means the triangle is isosceles
We have one angle that is greater than 90 degrees - that tells us the triangle is obtuse
Answer: Table 3
A table of values x and y represents a linear function,
if the change in x is always proportional with the change in y:
For example:
x changes from 1 to 2, y changes from -3 to -5
that is, a change of 1 in the x-es, is a change of +2 in the y's.
x changes from 2 to 4, y changes from -5 to -9
that is, a change of 2 in x, is a change of +4 in the y's.
1, 2 and 2, 4 are proportional
Another way we can check that Table 3 is the only one representing a linear function, is the constant change in y:
as x takes the values : 1, 2, 3, 4, y becomes -3, -5, -7, -9
that is, a constant change of 1 in the x-es, means a constant change of +2 in the y's
300x4=1200
10x4=40
5x4=20
add it up to get: 1260
