Answer:

$14/50\\$

Step-by-step explanation:

The equation for sine is sine = opposite/ hypotenuse

The opposite of W is 14 and the hypotenuse the the side across the 90° angle, which is 50.

So, when you set up the equation it should be $14/50$ .

A car rental company charges a $25.00 base fee plus $0.10 per mile driven to rent a car. How many miles did a customer drive if

slega [8]

Answer:

128 miles

Step-by-step explanation:

Given that a car rental company charges a $25.00 base fee plus $0.10 per mile driven to rent a car.

Let us represent y as total charges and x no of miles driven

Even if x=0, y= 25 (base fee)

SO y intercept =25

Slope = charge per drive = 0.10

So equation is

y =0.1x +25

To find out how many miles did a customer drive if the customers bill was $37.80, we can use the above equation.

y = 37.80 and x =?

37.80=0.1x+25

0.1x = 12.80

x = 12.80/0.1 = 128 miles

After visiting the Titanic, Captain Brain and Mr. Pinky are taking the Alvin submarine back to the surface of the water. They st

Answer:

$m=37h-1500$ .

Step-by-step explanation:

Let m represent meters and h represent hours.

We have been given that Captain Brain and Mr. Pinky start 1500 meters below the surface of the water and ascend at 37 meters per hour.

Since the submarine ascends at a rate of 37 meters per hour, so elevation of submarine after h hours would be $37h$ .

Since the elevation under water surface is negative, so 1500 meters below the surface of water would be $-1500$ .

The final elevation in meters of submarine after h hours would be initial elevation plus change in elevation after h hours that is $m=37h-1500$ .

Therefore, the equation $m=37h-1500$ . represents the given scenario.

A person invest $3000 in a bank the bank pays 6.75% interest compounded semi annually to the nearest 10th of a year how long mus

Monica [59]

Answer:

It would take 12.1 years.

Step-by-step explanation:

We are given with $3000 invested in bank pays 6.75% interest compounded semi annually to the nearest 10th. We are asked to find the number of years the bank reaches $6700.

Let's use the compound interest formula.

$A= P(1+\frac{r}{n}) ^{nt}$

We know A=6700

P=3000

r =0.0675

n=2(because compounded semiannually)

t =?( we need to find it)

Plug in the known values into the formula.

$6700=3000(1+\frac{0.0675}{2}) ^{2*t}$

Simplify and solve for 't'

Divide both sides by 3000

$2.23333= (1.03375)^{2t}$

Take log on both sides

$log(2.23333) = 2t log(1.03375)$

Divide both sides by log(1.03375)

24.2067=2t

Divide both sides by 2.

t=12.10...

To round to nearest 10th, we get t=12.1 years.
