Answer:
2
Step-by-step explanation: you can then easily do the area and divide by 2 :)
Let x be the time in hours and y be the distance driven in miles. If x = 0, then no time has passed which means he can't drive anywhere. So y = 0 when x = 0. The first point is (0,0). Note: the y intercept is 0 as this is where the graph crosses the vertical y axis.
One hour later, he has driven 35 miles because 140/4 = 35. In other words, his speed is 35 miles per hour (mph). So we have the second point (x,y) = (1,35). Note: the rate of change is the same as the slope in this problem. Also the rate of change is the same as saying "speed" for this problem.
Plot the two points (0,0) and (1,35) and draw a straight line through the two points. Extend the line as far as you can. The graph is linear assuming he maintains his speed to be the the same throughout the whole trip.
Answer:
(5) The perpendicular height of the triangle is 8.48 mm.
(6) The 1184.86 cm far up the wall the ladder reach.
Step-by-step explanation:
Part (5):
When a perpendicular is drawn in an isosceles triangle then the perpendicular divided the base into 2 equal parts.
The figures is shown below.
In ΔABC,
CB = 6 mm
So,
CD = BD = 3 mm
Now calculating the perpendicular height of the triangle.
Using Pythagoras theorem in ΔADC:
Thus, the perpendicular height of the triangle is 8.48 mm.
Part (6):
The figure is shown below.
Converting meter to centimeter:
1 m = 100 cm
So,
12 m = 1200 cm
Using Pythagoras theorem in ΔXYZ:
Thus, 1184.86 cm far up the wall the ladder reach.
The answer is c. The range fo the length of the fish caught by Freddy is greater than the range of the length of the fish caught by Waldo.
Answer: $8.95 per yard of fabric
Step-by-step explanation:
Define the following:
x = cost of fabric per yard
Make an equation:
⇒ 3x + 1.25 = 28.10
⇒ 3x = 26.85
⇒ x = 8.95
∴ $8.95 per yard of fabric
