Answer:
2+10+x=y or 10+2+x=y
Step-by-step explanation:
They get 2 dollars every ride and 10 dollars to get in but never gives you the amount of people or money made so you have to put in a substitute.
Hope this helps :3
(feedback is welcomed. Please dont be afraid to tell me my mistakes) <3
Area of a square = x² ( x is the length of a side)
Area = 36cm² = x² = 6²
length of one side of the square in the scale drawing = 6cm
since the diagram is scaled to 1cm : 3ft
the actual length = 6 × 3 ft = 18ft
the actual area = x² = 18² = 324 ft²
the ratio of the area in the drawing to the
actual area is
36 cm² : 324 ft²
to get the simplest ratio we divide both sides by 36 ( as 36 is the factor they both share in common)
the simplest ratio of the area in the drawing to the
actual area is
1 : 9
Hope you understood :)
Answer:
3/4 cups
Step-by-step explanation:
First convert 1 1/4 to an improper fraction which would give you 5/4. Next, you have to manipulate 5/4 and 1/2 so they have the same denominator, so you are able to subtract. So 1/2 = 2/4. Next subtract the two to get the remaining amount of flour. 5/4 - 2/4 = 3/4 cups.
Part (a)
Use the slope formula to compute the slope from x = 4 to x = 6
So effectively we're finding the slope of the line through (4,70) and (6,68)
We get the following
m = (y2-y1)/(x2-x1)
m = (68-70)/(6-4)
m = -2/2
m = -1
Repeat for the points that correspond to x = 6 and x = 8
m = (y2-y1)/(x2-x1)
m = (73-68)/(8-6)
m = 5/2
m = 2.5
Now average the two slope values
We'll add up the results and divide by 2
(-1+2.5)/2 = 1.5/2 = 0.75
The estimate of T'(6) is 0.75
This works because T'(x) measures the slope of the tangent line on the T(x) curve. Averaging the secant slopes near x = 6 will help give us an estimate of T'(6), which is the slope of the tangent at x = 6 on T(x).
<h3>Answer: 0.75</h3>
==============================================
Part (b)
The value T'(6) = 0.75 represents the instantaneous rate of change of the temperature per hour.
More specifically, T'(6) = 0.75 means the temperature is increasing by an estimated 0.75 degrees per hour at the exact instant of x = 6 hours. This instantaneous rate of change is like a snapshot at this very moment in time; in contrast, the slope formula results we computed above measure the average rate of change between the endpoints mentioned.
