Suppose you run 2 miles from your house to a friends house at a speed of 7 mi/hr. When the time comes to return home, you are tired and walk the same 2 miles at 3 mi/hr. How long did you spend running to your friends house? How long did you spend walking home?
Answer:
[tex]Time = 17.143\ mins[/tex] -- When going
[tex]Time = 40\ mins[/tex] -- When coming back
Step-by-step explanation:
Given
[tex]Speed\ to = 7mi/hr[/tex]
[tex]Speed\ from = 3mi/hr[/tex]
[tex]Distance = 2\ mi[/tex]
Required
Determine time taken to your friend's house
Determine time taken from your friend's house
Distance is calculated as:
[tex]Time = \frac{Distance}{Speed}[/tex]
From the question, we understand that:
[tex]Distance = 2\ mi[/tex]
When going:
[tex]Speed\ to = 7mi/hr[/tex]
So, we have:
[tex]Time = \frac{2mi}{7mi/hr}[/tex]
[tex]Time = \frac{2}{7}hr[/tex]
Express in Minutes
[tex]Time = \frac{2}{7} * 60[/tex]
[tex]Time = \frac{120}{7}[/tex]
[tex]Time = 17.143\ mins[/tex]
When coming back:
[tex]Speed\ from = 3mi/hr[/tex]
[tex]Time = \frac{2mi}{3mi/hr}[/tex]
[tex]Time = \frac{2}{3}hr[/tex]
Express in Minutes
[tex]Time = \frac{2}{3} * 60[/tex]
[tex]Time = \frac{120}{3}[/tex]
[tex]Time = 40\ mins[/tex]

3 times what Emily spent. Grace spent $36. Write and
solve an equation to find how much Emily spent. Let x
represent how much Emily spent.
and write an equation to represent the following description and use x as the variable
Answer:
Step-by-step explanation:
$39 plus the amount of money Grace had spent, $36.
39 + 36 = 75.
That gets rid of the "39 less than" part. But in order to find out how much money Emily spent you need to triple 75.
75 x 3 = 225
Therefore, x = 225 or $225 was the amount that Emily spent.

Step-by-step explanation:
HOPE THIS HELPS!!!
The steps will help show that circle A is similar to circle B is Dilate circle A by a scale factor of 4.
The correct option is (C).
What is Dilation?Dilation means changing the size of an object without changing its shape. The size of the object may be increased or decreased based on the scale factor.
Circle A has center of (0, 4) and a radius of 6
circle B has a center of (−3, 5) and a radius of 24.
The radius of circle A is 6 cm and radius of circle B is 24 cm, which 4 times the radius of circle A.
We know, Dilation is a transformation, which is used to resize the object. Dilation is used to make the objects larger or smaller.
This transformation produces an image that is the same as the original shape.
Thus, Dilate circle A by a scale factor of 4.

An amusement park ride lifts seated riders 265 feet above the ground. The riders are then dropped and experience free fall until the brakes are activated 105 feet above the ground. The function h=-16t^2+265 represents the height h (in feet) of the riders t seconds after they are dropped. How long do the riders experience free fall? Round your solution to the nearest hundredth.
The riders experience free fall for about ___ seconds.
Answer:
The riders experience free fall for about 3.12 seconds.
Step-by-step explanation:
Find t when h = 105
105= [tex]-16t^{2} +256[/tex]
0= [tex]16t^{2}[/tex] +160
0 = -16([tex]t^{2}[/tex]-10)
[tex]t^{2}[/tex] - 10 = 0
[tex]t^{2}[/tex] = 10
[tex]t = \sqrt{10}[/tex]
The riders experience free fall for about 3.16 seconds.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
To find how long the riders experience free fall, we need to find the time when the height is 105 feet above the ground.
So, we need to solve the equation:
-16t² + 265 = 105
Adding 16t² to both sides, we get:
16t² = 160
Dividing both sides by 16, we get:
t² = 10
Taking the square root of both sides, we get:
t = ±3.16
Since we are only interested in the positive value of t, we can round 3.16 to the nearest hundredth to get:
t = 3.16 seconds
Therefore,
The riders experience free fall for about 3.16 seconds.

Step-by-step explanation:
Given
[tex]Distance = 3\frac{1}{6}km[/tex]
[tex]Time = \frac{1}{4}hr[/tex]
Required
Determine the average speed
Average speed is calculated as thus;
[tex]Speed = \frac{Distance}{Time}[/tex]
[tex]Speed = 3\frac{1}{6}/\frac{1}{4}[/tex]
[tex]Speed = 3\frac{1}{6} * \frac{4}{1}[/tex]
Convert Mixed Fraction to Improper fraction
[tex]Speed = \frac{19}{6} * \frac{4}{1}[/tex]
[tex]Speed = \frac{19 * 4}{6 * 1}[/tex]
[tex]Speed = \frac{76}{6}[/tex]
Divide both sides of the fraction by 2

AB & BC are two sides of a regular octagon. Calculate the size of angle x.
Answer:
x = 45°
Step-by-step explanation:
the sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
here n = 8 ( number of sides of an octagon ) , then
sum = 180° × 6 = 1080°
the interior angles of a regular octagon are congruent , so
∠ ABC = 1080° ÷ 8 = 135°
x and 135° are adjacent angles on a straight line and sum to 180° , then
x = 180° - 135° = 45°
