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.
Answer:
16 rows, 8 seedlings left.
Step-by-step explanation:
Divide 200 by 12, since 200 seedlings are going to be split in 12 groups in order to fill the rows.
200 ÷ 12 = 16 with a remainder of 8.
The remainder is basically what is left.
Since 12 seedlings are planted in each row, 8 seedlings is not enough to completely fill the row. So, the answer is 16 rows with 8 seedlings left.

Answer:
(x,y) --> (1/7x, 1/7y)
Step-by-step explanation:
Answer:
730 g of olives
Step-by-step explanation:
First, convert 1 kg of olives to 1,000 g of olives.
Since he uses 30 grams per loaf, and makes 9 loaves, multiply 30x9, which equals 270g. This means he used 270 g of olives.
To find how many he has left, you subtract the amount he used from the amount he started with:
1,000 - 270 = 730 g
There’s no answer for that it just depends
