Answer: The required distance between the top and bottom of the bridge is 76 feet.
Step-by-step explanation: Given that a new bridge structure requires triangles that are in a ratio of 1:1.
AC = 2x + 10 and EC = 4x − 18.
We are to find the distance between the top and bottom of the bridge, in feet.
Since the two triangles ACB and DCE are in the ratio 1 : 1, so their corresponding sides are also in the ratio 1 : 1.
The sides AC and EC are corresponding to each other, so we must have
Therefore, the distance between the top and bottom of the bridge is
Thus, the required distance between the top and bottom of the bridge is 76 feet.

Answer:
80.88
Step-by-step explanation:
The mean is the average of the numbers. To calculate that, just add up all the numbers, and then divide by how many numbers there are. In other words it is the sum divided by the count.
95 + 45 + 37 .....
divided by 24 (the total number of numbers)
1,941 / 24 = 80.875
80.8<u>7</u>5 rounded to the nearest hundredth = 80.88

(hundredths place)
Rounding rule: If the digit to the right of the place you are rounding to is 5 or more, then round up to the next digit.
Answer:
1/6
Step-by-step explanation:
The number you can get more than 5 on a dice is 6.
1 number out of total 6 numbers on the dice.
= 1/6
Answer:
Step-by-step explanation:
( a + b )( a - b ) = a² - b²
( 1 + sin x )( 1 - sin x ) = 1² - sin² x = cos² x
