Help me please i don't understand ​

Mathematics
1 answer:
lubasha [3.4K]3 years ago
7 0

Answer:

See below.

Step-by-step explanation:

Variables:

L = length

W = width

P = perimeter

Equations:

L = W + 13

P = 2(L + W)

P = 2(W + 13 + W)

2(W + 13 + W) = 226

2(2W + 13) = 226

2W + 13 = 113

2W = 100

W = 50

L = W + 13 = 50 + 13 = 63

The length is 63 cm, and the width is 50 cm.

Priscilla can make 4 bracelets in 17 minutes. At this rate, how many bracelets can she make in 34 minutes?
andrew11 [14]
4 bracelets/17 minutes = x bracelets/34 minutes
cross multiply: 4 · 34 = 17 · x
Divide both sides by 17: (4 · 34)/17 = x

An observer (O) spots a plane flying at a 42° angle to his horizontal line of sight. If the plane is flying at an altitude of 15
NeTakaya

Answer:

D. 22,417 feet

Step-by-step explanation:

Fine the diagram in the attachment for proper elucidation. Using the SOH, CAH, TOA trigonometry identity to solve for the distance (x) from the plane (P) to the observer (O), the longest side x is the hypotenuse and the side facing the angle of elevation is the opposite.

Hypotenuse = x and Opposite = 15,000feet

According to SOH;

sin 42^0 = \frac{Opposite}{Hypotenuse} \\\\Sin42^0 = \frac{15000}{x}\\ \\x = \frac{15000}{sin42^0}\\\\ \\

x = \frac{15000}{ 0.6691} \\\\x = 22,417 feet

Hence the distance (x) from the plane P to the observer O is approximately 22,417 feet
