The equation for the line containing the vertical right edge of the arch is x = 60.
The line representing the right edge is the line passing through the parabola on the right side at y = 20.
It is given that the left edge of the arch is the y-axis.
The parabola and the vertical base are symmetrical.
We can see that the left edge begins (0, 20). This means that the right edge would also have y = 20.
Observe the given graph. We can see that the parabola passes y = 20 again at the point (60, 20).
This means that the equation of the line representing the right edge is x = 60.
Therefore, we have found the equation for the line containing the vertical right edge of the arch to be x = 60.

Answer:
The answer is x=60.
Since the arch and its base are symmetrical, so that other side of arch should be at (x, 20). Refer to x-axis when y is equal to 20. Thus, x=60.
I just took the test and the answer is correct.

Step-by-step explanation:
This can be solved with proportions.
Cross multiply and you get:
Divide by 2.58 gallons and you get:
And to find out the number of hours that is, divide by 60 and you get 1.73 hours.
Answer:
Planet X weighs less than planet earth
Step-by-step explanation:
Planet X will weigh less than planet earth because its gravitational pull is only 40% of planet earth . This means that planet earth is heavier than Planet X .
Answer:
1 5/6
Step-by-step explanation:
We first convert each mixed number to an improper fraction.
To change -6 7/8, we will ignore the negative at first. Multiply the whole number by the denominator:
6(8) = 48
Add the numerator:
48+7 = 55
Putting the negative back in, we have -55/8.
To change -3 3/4, ignore the negative at first. Multiply the whole number by the denominator:
3(4) = 12
Add the numerator:
12+3 = 15
Putting the negative back in, we have -15/4.
This gives us
-55/8 ÷ -15/4
To divide fractions, flip the second one and multiply:
-55/8 × -4/15
Multiply straight across:
(-55×-4)/(8×15) = 220/120
Simplifying this, we know that both 220 and 120 are divisible by 10; this gives us
22/12
Both 22 and 12 are even, so they are both divisible by 2. This gives us
11/6
6 will go into 11 one time, with 5 remaining; this gives us
1 5/6
