a:tan0= 12/5
b:sec0= 12/13
c: sin0=12/13
d: cos0=12/13

Answers

Answer:

a:tan0= 12/5

c: sin0=12/13

Step-by-step explanation:

cosec t(heta) = 13/12

1/sin t = 13/12

sin t = 12/13

cos t = √ (1 - (12/13)² ) = √ ( 1 - 144/169 ) = √25/169

cos t = 5/13

tan t = sin t/ cos t = (12/13) / (5/13) = 12/5

sec t = 1 / cos t = 13/5

Answer: A ) and C )  are correct:

tan theta = 12/5 and sin theta = 12/13

Two mechanics worked on a car. The first mechanic worked for 5 hours, and the second mechanic worked for 15 hours. Together they charged $1650. What was the rate charged per hour by each mechanic if the sum of the two rates was $140 per hour?

Answers

x = rate of mechanic who worked 5 hours
y = rate of mechanic who worked 15 hours

Then

x + y = 235
5x + 15y = 2375

Just solve these 2 equations above for x and y.

x + y = 235 ⇒ x = 235 - y

Substitute into second equation to find y.

5(235 - y) + 15y = 2375

1175 - 5y + 15y = 2375

10y = 1200

y = 1200/10 = 120

x = 235 - y = 235 - 120 = 115

The mechanic who worked 5 hours charged $115 per hour, the one who worked 15 hours charged $120 per hour.

I = $141.60; P = $590; t = 6 years
Find the rate

Answers

To find the rate, you need to have the equation for r.

Using the simple interest formula:

I = P • r • t

Divide both sides by P•t to isolate r:

I / P • t = (P • r • t)/ P • t

I / P • t = r

Now that we have the formula for r, substitute the given values into the equation:

r = $141.60/($590 • 6)
r = 0.04 or 4%

Therefore, the interest rate is 4%

You have 7 times as many nickels
as pennies. You have 16 nickels
and pennies altogether. How
much money do you have in all?

Answers

The total money you have is $40.14.

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

Now it is given that,

There are 7 times as many nickels as pennies

Let there are n nickles and p pennies.

⇒ p = 7n

Now, there are  16 nickels and pennies altogether

⇒ p + n = 16

Put p = 7n we get,

⇒ 7n + n = 16

⇒ 8n = 16

⇒ n = 16/8

⇒ n = 2

Therefore,  p = 7*2

⇒ p = 14

Thus there 14 pennies and 2 nickels.

Now, since 1 penny = 0.01 dollars

and 1 nickel = 20 dollars

⇒ 14 pennies = 14*0.01 dollars = 0.14 dollar

and, 2 nickel = 2*20 dollars = 40 dollars

So, Total money = $40 + $0.14

Total money = $40.14

Thus, the total money you have is $40.14.
