Answer:
B.540
Step-by-step explanation:
For a nomber to be divided by 2 the last digit must be even
for a number to be divided by 3 the sum of number's digits must be 3's multiple
for 5 the last digit must be 5 or 0
for 6 the number can be divided by 2 and 3
and for 9 the sum of number's digits must be 9's multiple
for 10 the last digit must be 0.
Answer:
14
Step-by-step explanation:
52,259 divided by 215 is 243.065116279
so we know that the nearest whole number is 243.
243x215 is 52,245
subtract 52,245 from 52,259 which gives you the remainder of 14
To find 33% of 1.45 we have to transform 33% into decimal or fraction
33% is 0.33 or and multiply if by 1.45
so
0.33*1.45=0.4785
Answer:
slope of perpendicular line = -
Step-by-step explanation:
calculate the slope m of the given line using the slope formula
m =
with (x₁, y₁ ) = (1, 0) and (x₂, y₂ ) = (3, 3) ← 2 points on the line
m = =
given a line with slope m then the slope of a line perpendicular to it is
= - = - = -
To factor both numerator and denominator in this rational expression we are going to substitute
with
; so
and
. This way we can rewrite the expression as follows:
Now we have two much easier to factor expressions of the form
. For the numerator we need to find two numbers whose product is
(30) and its sum
(-11); those numbers are -5 and -6.
and
.
Similarly, for the denominator those numbers are -2 and -5.
and
. Now we can factor both numerator and denominator:
Notice that we have
in both numerator and denominator, so we can cancel those out:
But remember than
, so lets replace that to get back to our original variable:
Last but not least, the denominator of rational expression can't be zero, so the only restriction in the variable is
