Answer:

B. a ⊥ d

Step-by-step explanation:

If lines "a" and "d" are in the same plane, they are perpendicular to each other. If not, there is no relationship between the lines.

Lines parallel to the same line are parallel to each other, so a║c. <em>In the same plane</em>, a line perpendicular to one of two parallel lines is also perpendicular to the other. (For example, one side of a rectangle is perpendicular to both of the adjacent sides, which are parallel to each other.)

The appropriate choice is ...

a ⊥ d

<em>In 3 dimensions, ...</em>

Consider a cube. A given edge will be perpendicular to both of the two edges it meets at a corner.

It will not intersect (has no "perpendicular" relationship to) either of the edges parallel to those that meet at the corner at the other end of the space diagonal.

olivia has $180 to buy presents for her 3 sisters and 2 nephews. She wants to spend $15 more on each sister than she spends on e

koban [17]

So
if x is the number she spent on each sister and y is the number she spent on each nephew then
180=3x+2y

she wants to spend 15 dollars more on sisters than nephews
so
x=15+y
solve

we have
180=3x+2y and
x=15+y
subsitute 15+y for x

180=3(15+y)+2y
180=45+3y+2y
180=45+5y
minus 45 both sides
135=5y
divide both sides by 5
27=y

solve for x
x=15+y
x=15+27
x=42

she spent $42 on each sister

The population of Canyon Edge is 210,000, and the rate of population growth is 12.5%.

sergejj [24]

For this case we have a function of the form:
$y = A * (b) ^ x
$
Where,
A: initial population
b: growth rate
x: number of years.
We then have the following function:
$y = 210000 * (1,125) ^ x
$
For x = 4 years we have:
$y = 210000 * (1,125) ^ 4

 y = 336379$
Answer:
the formula for exponential growth is:
y = 210000 * (1,125) ^ x
The population of Canyon Edge after 4 years is:
y = 336379

If the diameter of a circle is 5 centimeters, how long is the arc sub tended by an angle measuring 60 degrees?

jenyasd209 [6]

Answer:

3/5pi

Step-by-step explanation:

The formula of getting the arc length is

arc length = angle * pi / 180 * r

arc length = 60 * pi / 180 * 5

arc length = 300 * pi / 180

arc length = 5pi / 3
