Answer:
The length of the bridge is 126.492 feet.
Step-by-step explanation:
Let 
, where 
is the position from the middle of the bridge, measured in feet, and 
is the height of the bridge at a location of x feet, measured in feet. In this case, the length of the bridge is represented by the distance between the x-intercepts of the parabola, which we now find by factorization:
(Eq. 1)
Given that the parabola is symmetrical with respect to y-axis, then the length is two times the magnitude of the value found above, that is:
The length of the bridge is 126.492 feet.
Step-by-step explanation:
<u>The standard form of linear equation:</u>
<u>Convert each equation into standard form:</u>
<h3>#5</h3>
- 3x = 18
- 3x + 0y - 18 = 0
- A = 3, B = 0, C = - 18
<h3>#6</h3>
- y/2 = - 5
- 0x + 1/2y + 5 = 0
- A = 0, B = 1/2, C = 5
Eatin time is 8 pm....her meal takes 65 minutes to cook...well, 60 minutes is an hr...so that knocks it down to 7 pm....and then we take away the 5 minutes....so we put the food in the oven at 6:55 pm....oh...on a 24 hr clock...that's 18:55
Answer:
40 miles is her goal.
Step-by-step explanation:
The problem says that 24 miles is 60% of her goal for that month.
You cab make a proportion with x being the goal for the whole month.
24/x = 6/10
You cross multiply and get:
6x = 24 x 10
6x = 240
x = 40
40 miles is the answer.
Let the unknown be n, then:
n × 3 = 8 × 2
n × 3 = 16
n = 16 ÷ 3
n = 5.333
