Answer:

110 3/16

Step-by-step explanation:

Area = l x w

L = 10 1/4

A = 99 15/16

99 15/16 ÷ 10 1/4

= 110 3/16

Madeline drove 180 miles in 4 hours. If she drove at a constant rate, how far did shetravel in one hour?On the double number lin
Tcecarenko [31]

We have a question on motion with the elements of distance, time taken and speed.

This question in particular is asking us for distance per unit time (in this case, hours).

We are required to find out how much distnace is covered in on hour and our approach will be as follows:

\text{Speed= }\frac{\text{Distance}}{\text{time}}=\frac{180\text{miles}}{4\text{hours}}=\frac{45\text{ miles}}{1\text{ hour}}

This right here just tells us that 4 hours, Madeline covered 180 miles and since her rate was constant (equal distances in equal times), then she also covered 45 miles in an hour.

Now we plot our number line.

Find sin3A, cos<br> 3A and tan 3A when sin=1/2<br>​
Slav-nsk [51]

Answer:

Sin 3A = 1

cos 3A = 0

tan 3 A = undefined

Step-by-step explanation:

\sin A =  \frac{1}{2}  \\  \therefore \: \sin A =   \sin \: 30 \degree.. \bigg( \because \: \sin \: 30 \degree =  \frac{1}{2} \bigg) \\ \therefore \: A =   30 \degree \\  \\ now \\   \sin 3A =\sin (3 \times 30 \degree)= \sin \: 90 \degree = 1 \\  \\  \cos 3A =\cos (3 \times 30 \degree)= \cos \: 90 \degree = 0\\\\ \tan 3A =\tan (3 \times 30 \degree)= \tan \: 90 \degree =  \infty
