If CosA= sqrt 3/2, what is TanA?

Answers

Answer:

√(3)/3

Step-by-step explanation:

cos(A) = adj./hyp.

adj. = √(3) or √(3)/2

hyp. = 2 or 1

use unit circle:

hyp. = 1

adj. = √(3)/2

use pythagorean theorem c² - b² = a²

1² - (√(3)/2)² = 1 - 0.75 = 0.25

a² = 0.25

a = √(0.25)

a = 0.5

tan(A) = opp./adj.

tan(A) = 0.5/(√(3)/2)

tan(A) = 1/√(3)

rationalize

tan(A) = √(3)/3

A cell phone company expects that every 2 out of 25 cell phones will have some formof defect. At this rate, how many cell phones out of 500 will be expected to have a defect?

Answers

Answer: 40 phones

Step-by-step explanation:

The company expects that every 2 out of 25 phones will have some form of defect.

In percentage terms, this is:

= 2 / 25 * 100%

= 8%

If there are 500 phones therefore, the defected phones would still be the same percentage and the actual number would be:

= 8 % * 500

= 40 phones

S part of a statistic project, a math class weighed all the children who were willing to participate as shown below.

How many children weighed less than 50 pounds?

Answers

Answer:

18 children weighed less than 50 pounds.

Step-by-step explanation:

Ok, adding into the explanation what the heck this kind of a table is. The "stem" column is the tens place of each of the children's weights. The "leaf" is the ones digit of each of the children's weights. So in the row where the stem is 2, there were 2 kids weighing 23 and 25 pounds.

For your question, we have to add up how many students have a weight with a "stem" less than 5, because that's where 50 pounds starts.

8 + 2 + 5 + 3 = 18 children weighed less than 50 pounds.

if 20% of a number is 386, what will be 30% of the same number

Answers

if the 20% of a number is 386, what will be 30% of the same number

Answer will be 157

If 20% of a number is 386, 30% of the same number is 579

How to determne the number?

Let the number be x.

So,we have:

20% * x = 386

Express 20% as 0.20

0.20 * x = 386

Divide both sides by 0.20

x = 1930

30% of the number is represented as:

30% * 1930

Evaluate the product

30% * 1930 = 579

Hence, 30% of the same number is 579

The image shows the angles formed by a pair of scissors. When the scissors are closed, m∠1 = 0°. As the scissors are opened, the measures of all four angles change in relation to each other.
Describe how the measures change as m∠1 increases from 0° to 180°.

Answers

Angle 3 is a vertical angle of angle 1 and will always be identical to what angle 1 is.

Angle 2 and angle 4 are supplementary angles to angle 1 and will always be the difference between 180 and what angle 1 is.

For example if angle 1 was 45 degrees, angle 3 would also be 45 degrees and angle 2 and angle 4 would be 180-45 = 135 degrees.

14% approx

Step-by-step explanation:

Given data

Initial= $18.00

final =$20.50

% increase= final - initial/initia *100

% increase= 20.50-18.0/18*100

% increase=2.5/18*100

% increase=0.138*100

% increase=13.8%

Hence the increase is 13.8%
