Hello!

\large\boxed{66.32 m}

We are given the area, so we can solve for the width given the length:

A = l × w

Thus:

272.4 = 15 × w

w = 18.16 m

The perimeter of a rectangle can be calculated using this equation:

P = 2l + 2w

Therefore:

P = 2(15) + 2(18.16)

P = 30 + 36.32 = 66.32m

A professor determined the relationship between the time spent studying (in hours) and performance on an exam.
kykrilka [37]
Step 1: Insert 2.6 hours for the variable of time and solve.
70.443 + 4.885(2.6)
70.443+ 12.701
= 83.144
This is Ann's EXPECTED exam score.  Because of the concert, Ann scored 16 points lower than this number.
Step 2: Subtract 16 from Ann's expected score.
83.144 - 16
= 67.144

Find the answer to each trigonometric function below. ​
Airida [17]

Answer:

  • Sin A = \frac{opposite}{hypotenuse} =\frac{32}{40} =\frac{4(8)}{5(8)} =\frac{4}{5}
  • Cos C = \frac{adjacent}{hypotenuse} =\frac{16}{34}=\frac{2(8)}{2(17)} =\frac{8}{17}
  • Tan A = \frac{opposite}{adjacent} =\frac{21}{20}

An aircraft is approaching the runway to land The aircraft is at a height of h= 314 meters from the runway. The angle of
Shtirlitz [24]

Answer:

easy peasy

Step-by-step explanation:

u see,

the height of the airplane from the ground is 314m

but with the tower's horizontal plane, it would be

=> altitude of aircraft - height of tower

=> 314 - 70 = 244 m

now in the ABC,

using the ratio of sine,

sin 16 = AB/AC

=> 0.275 = 244/AC

=> AC = 244/ 0.275

=> AC = 887.9...

=> AC = approx. 886 meters
