2 x 230 = 231
I’m not 100% sure if this is correct?? Hope it helps though
We can define the speed as the quotient between the distance moved, and the time it takes to move that distance, so we have:
<u>speed = Distance/Time.</u>
Now we can rewrite this as:
<u>Distance = Speed*Time.</u>
We will find that the speed of the car was 21 mi/h.
Here the information given is:
Mr. Pipkins speed is: S = 3.5 mi/h
The car needed 27 "steps" to reach the corner.
Mr. Pipkins needed 27 + 135 = 162 "steps" to reach the same corner.
Because the number of steps is related to time and distance, the ratio between the number of steps should be the same as the ratio between the speeds:
162/27 = 6
(Pipkins needed 6 tomes more steps than the car, so the car moves 6 times faster than Pipkins)
This means that the speed of the car is 6 times larger than the speed of Mr. Pipkins.
Then the speed of the car is:
S' = 6*(3.5 mi/h) = 21 mi/h.

Answer:
Step-by-step explanation:
The equation of a line
y = mx + c
y - intercept point y
m - slope of the line
x - intercept point x.
c - intercept of the line
Step 1: find the slope
m = y2 - y1 / x2 - x1
Given two points
( -7 , -7) ( -7 , 4)
x1 = -7
y1 = -7
x2 = -7
y2 = 4
Insert the values into the equation
m = 4 - (-7) / -7 -(-7)
m = 4 + 7 / -7 + 7
m = 11/ 0
Step 2: sub any of the two points given into the equation
y= mx + c
y = 11/0x + c
(-7 ,4 )
x = -7
y = 4
4 = 11/0(-7) + c
4 = -77/0 +c
-77/0 is math error which means that the points are not correct
Answer:
200 ft²
Step-by-step explanation:
Each face is an isosceles right triangle with a hypotenuse of length 10 ft. The area of each of those triangles is
A = 1/4·h² . . . . where the h in this formula is the hypotenuse length
So, the area of the four faces (the lateral area of the pyramid is 4 times this, or ...
A = 4·1/4·(10 ft)² = 100 ft²
Of course, the base area is simply the area of the square base, the square of its side length:
A = (10 ft)² = 100 ft²
So, the total area is the sum of the lateral area and the base area:
total area = 100 ft² +100 ft² = 200 ft²
_____
If you think about this for a little bit, you will realize the pyramid must have zero height. That is, the slant height of a face is exactly the same as the distance from the center of an edge to the center of the base. "Not drawn to scale" is a good description.
The answer to this is -1/6
Decimal form: -0.16 (underline on the 6 which represents repeating number)
