Answer:
-1 17/25
Solution with Steps
−65−1225=?
The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.
LCD(-6/5, 12/25) = 25
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
(−65×55)−(1225×11)=?
Complete the multiplication and the equation becomes
−3025−1225=?
The two fractions now have like denominators so you can subtract the numerators.
Then:
−30−1225=−4225
This fraction cannot be reduced.
The fraction
−4225
is the same as
−42÷25
Convert to a mixed number using
long division for -42 ÷ 25 = -1R17, so
−4225=−11725
Therefore:
−65−1225=−11725
25 is equal to 1/4
to find 1/4 of a number, you divide the number by 4.
the equation here is:
x ÷ 4 = 40
to solve, do 40 x 4 = 160
x = 160
40 is 25% of 160
Answer:
9
Step-by-step explanation:
Let the equation of a parabola be
= 4ax.
Then , focal length of the parabola is a.
As , (0,0) is the vertex and its focus is (a,0)
Thus, focal length comes out to be a.
Here,
a is given as 9 units .
Thus focal length of the parabola, d, equals to 9 units
Answer:
Constant
Step-by-step explanation:
For a straight line for example,
Take any two points from the line and find the slope,
it will be the same value for any 2 points chosen
So throughout the graph, the slope/rate of change is not changing
That is
Throughout the graph rate of change/slope is constant
