First, let's make 1 1/4 into a improper fraction. So 1 whole is 4/4 and then add the 1/4. So 4/4+1/4 is 5/4. Now let's make 3 into the same common denominator. So 3=3/1. Now let's use the identity property to multiply it by 4, since we want the common denominator to be 4. 3/1 x 4/4 is 12/4. Now we can finally add. When we add, we only add the numerators. So 12/4+5/4 is 17/4. The fraction symbol is another way saying division. So 17 divided by 4 is 4 r 1. We make the remainder into a fraction and use 4 as a whole number. So our answer is 4 1/4.

Real answer: 4 1/4

Norma-Jean [14]

Answer:

547 m

Step-by-step explanation:

Given :

Angle of depression, θ = 63°43' ; 43/60 = 0.7167 = 63 + 0.7167 = 63.7167°

The height, h = 270

The distance of park bench from the building, d is given by :

Tan θ = opposite / Adjacent

Tan 63.7167 = d / 270

d = 270 * Tan 63.7167

d = 546.70459

d, distance of Park bench from building is 547 m

5. During the season, the Rangers played 25 games. They won 14 of the games.
sertanlavr [38]
Answer is 11/25 games lost which is 44%.

Step by step. 25 games minus 14 they won equals 11 games lost out of 25.

11 out of 25 = 11/25.

11/25 as a % - 11 divided by 25 = .44 which is 44%.

Check your work, 44% of 25 games = 11 games lost.
Problem solved.
