What is the exact value of sec(-405degress)?? ...?

Answers

Answer 1

Answer: sec= 1/(cos), you can add or subtract 360 degrees from any angle measurement without changing the value of any of the trig functions i.e. 405 degrees= 405-360=45. cos of 45 is sqrt(2)/2 so sec405= 2/sqrroot2

Answer:

Adam's total cost: $9.20

Cindy's total cost: $9.20

Step-by-step explanation:

Since Adam and Cyndi's total bill costs $16, evenly splitting the cost means that each of them has to pay $8, not including the tip.

To find out the dollar value of their 15% tip, multiply $8 by 0.15:

$8 × 0.15 = $1.20.

Adam and Cindy will have to pay $8 (lunch cost) + $1.20 (tip) = $9.20 separately.

16 men are employed to do a work in 20 days. at the end of 12 days the work is only half done. how many additional number of men should be employed to complete the work in the stipulated time?

Answers

16 men in 12 days can do 0.5work
1 man 1 day can do 0.5/(16x12) of a work

8days to do 0.5 of a work
1 man 8 days can do 8x0.5/(16x12) = 0.5x(1/24) of a work
... if you notice we need 24 men

... more detail
in8days, 0.5x(1/24) of a work need 1 man
in8days, 0.5 of a work need 0.5/(0.5x(1/24)) = 24 men

point is to find 'amount of work done per man per unit of time' then work out from that.

Jeff's club had $370 to divide equally among 2 people. About how much did each person receive? First, round the amount to the nearest hundred dollars. Each person received approximately $______.

Answers

Answer:

$185.

Step-by-step explanation:

To find out how much each person received, we can divide the total amount of money, which is $370, by the number of people, which is 2.

370 ÷ 2 = 185

Therefore, each person received approximately $185.
