Two hikers walk on a trail in the direction of increasing mile marker numbers. Mandy starts at mile marker 1 and hikes at a rate of 2.5 miles per hour. At the same time, Rita starts at mile marker 2 and hikes at a rate of 3 miles per hour. The equation 2.5h+1=3h+2 represents the number of hours h it will take Mandy to catch up with Rita.
Let as consider, we need to find the number of hours h it will take Mandy to catch up with Rita.
Given:
The number of hours h it will take Mandy to catch up with Rita is represented by the equation
[tex]2.5h+1=3h+2[/tex]
To find:
The value of h.
Solution:
We have,
[tex]2.5h+1=3h+2[/tex]
Isolate the variable terms on one side.
[tex]2.5h-3h=-1+2[/tex]
[tex]-0.5h=1[/tex]
Divide both sides by -0.5.
[tex]h=\dfrac{1}{-0.5}[/tex]
[tex]h=-2[/tex]
We know that, time cannot be negative. So, [tex]h\neq -2[/tex].
The equation [tex]2.5h+1=3h+2[/tex] is not true for any positive value of h.
Therefore, Mandy will never catch up with Rita.

An angle is 36⁰ less than its complement. What is the measure of the angle?
Answer:
27 degrees.
Step-by-step explanation:
If the angles are x and y then as they are complementary:
x + y = 90 - and we are given that:
x - y = 36 Adding the 2 equations:
2x = 126
x = 63.
So 63 - y = 36
y = 63 - 36 = 27.

Answer:
7^3 + 7^3 units^3
OR
(7^3)2 units^3
Step-by-step explanation:
Volume = length x width x height
In cubes, length = width = height
So, volume = 7 x 7 x 7 = 7^3

HOPE THIS HELPEDDDD ❤✨
Answer:
The original price of the candles was $4.69
Step-by-step explanation:
$11.96 (price of 4 candles) ÷ 4 candles = $2.99 (how much each candle costs)
$2.99 (how much each candle costs) + $1.70 (how much the price of the candles lowered) = $4.69 (the old price per candle)

There is a bag filled with 5 blue and 6 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is replaced.
Another marble is taken at random.
What is the probability of getting at least 1 red?
Answer:
There are 6+5 marbles.
Of those, 5 are red.
The chances of drawing a red marble are 5/11
Since you replace the marble you drew, the chances each draw remain 5/11
You cannot draw two red marbles without drawing a red marble on your first draw, so the odds of you making a second draw are 5/11. The odds of that also being red are 5/11… but we only care about that 5/11ths the time
5/11*5/11=25/121

If two lines are parallel and the slope of one of the lines is M, what is the product of their slopes? *
2 points
1
2M
M²
-1
Thanks will mark brainliest
Answer:
M²
Step-by-step explanation:
Parallel lines have equal slopes.
One line has a slope of M then the line parallel to it has a slope of M , thus
product of slopes = M × M = M²
The the product of their slopes is M².
What is slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx
where, m is the slope
Given:
two lines are parallel
and the slope of one of the lines is M
Also, the parallel lines have the same slope.
So, both the line lines have slope M.
Now, the the product of their slopes
= M x M
= M²
Hence, the product of their slopes is M².
