Answer:
70 centimeters squared
Step-by-step explanation:
area of trapezoid formula is 1/2 (b1 + b2)
1/2 (7+13)(7)
7 is base 1, 13 is base 2, 7 is the height
1/2(7+13)(7)
1/2(20)(7)
1/2(140)
70
There are 1600 metres in 1 mile, so 10095÷1600= 6.3 miles/s
We determine the minimum and maximum scores that Juan needs to get in order to be within the strict average range. We let x be his score.
minimum:
74 = (82 + x) / 2
The value of x from the equation is equal to 66.
maximum:
80 = (82 + x )/2
The value of x from the equation is equal to 78.
Hence, Juan's score should fall between 66 and 78, inclusive.
Answer: <em> 66 ≤ x ≤ 78</em>
d)
y = mx + c
m = slope
c = y-intercept
slope = 8
e)
y-intercept = (0, 250,000)
f)
This is a line running bottom-left to top-right with a slope of 8. To draw the graph, you need to connect two coordinates.
y-intercept = (0, 250,000)
0 = 8x + 250,000
x = - 31,250
x-intercept = (- 31,250, 0)
Draw the axes and label them x and y.
