Answer:
b = -a
Step-by-step explanation:
We know that:
On a number line, the distance between 0 and b is the same distance that between 0 and a (but b and a are in opposite sides of zero).
And we know that, for example, when:
b = 2, a = -2
Remember that the distance between two values is given by:
|n - m|
Then the distance between 0 and b is:
|0 - b|
and the distance between 0 and a is:
|0 - a|
we have:
|-b| = |-a|
|b| = |a|
But the numbers are in opposite sides of the zero, so one must be positive and the other negative, then we can conclude that:
b = -a
or
-b = a
(these are equivalent)
Then the correct option is the first option:
b = -a
Answer:
$91.75
Step-by-step explanation:
She earns $2.15 an hour and worked 20 hours this week so
20 × 2.15 = 43 and she earned 15% tip off the meals she served
to calculate how much 15% of 325 does we multiply 325 with 15 and divide it with 100
325 × 15 ÷ 100 = 48.75
48.75 + 43 = 91.75
Neither of those work for that equation
If l || m than 8x+20=11x-31
3x=51
x=17
The angles are obtuse angles.
Step-by-step explanation:
Volume of a cylinder is given by cross sectional area multiplied by height hence
V=Ah
Since the cross sectional area of
Substituting the formula for A into formula for volume then
Substituting 8ft for r and 20 ft for h then
Rounded off to the nearest tenths, the volume is equivalent to
