Answer:

We found sinA= 3/5 and cosA=4/5

Option A is correct.

Step-by-step explanation:

The formula to find sin A is :

sin A = \frac{Perpendicular}{Hypotenuse}

while the formula to find cos A is:

cosA=\frac{Base}{Hypotenuse}

So, in the figure given:

Base = 16

Perpendicular = 12

Hypotenuse = 20

Now, finding sin A and cos A using formulas and above values

sin A = \frac{Perpendicular}{Hypotenuse}\\sin A = \frac{12}{20}\\sinA=\frac{3}{5}

cosA=\frac{Base}{Hypotenuse}\\cosA=\frac{16}{20}\\cosA=\frac{4}{5}

So, we found sinA= 3/5 and cosA=4/5

Option A is correct.

8. What is the distance around the clock?
Elan Coil [88]

Answer:

The clock face is divided into sixty equal parts, each minute. The minute hand is located on the 20 minute mark at 6:20, the hour hand located between the 30 minute mark and the 35 minute mark. When the minute hand goes all sixty minutes, the hour hand only moves five, so to figure out the location of the hour hand, we look at how much the hour has progressed, in this case 20 minutes, or one third of the hour. So the minute hand has moved one third of the way through the hour, so has the hour hand moved one third of the way through the five minutes, or, five thirds of a minute, which is one and two thirds minute, one minute forty seconds. That puts the hour hand at thirty minutes plus one minute and forty seconds—at 31min 40sec—which is 11min 40sec farther than the minute hand.

tia_tia [17]

It is given in the question that

After being discounted 40%, a weather radio sells for $35.97.

It means the weather radio sells at a 60% of original price.

Let the original price be $x.

Therefore according to the question,

60% \ of \ x = 35.97
\\
0.6x = 35.97
\\
x = $59.95

Therefore the original price of the weather radio is $59.95.
