7/12 x 4= 28/12 and good luck again
1 mile is equal to 1.6 kilometers, so 8 miles (using a direct proportion) should be equal to 8 * 1.6 = 12.8 kilometers. The cyclist rides at 12.8 kilometers per hour. In four hours, the cyclist would have rode 12.8 * 4 = 48 + 3.2 = 51.2 kilometers.
The sales tax is 6.7% from $498.00 -> The sales tax = 498 x 6.7% = $33.366.
The total cost of the trampoline = 498 + 33.366 = $531.366
We have been given that in ΔRST, the measure of ∠T=90°, SR = 65, TS = 33, and RT = 56. We are asked to find the value of sine of ∠R to the nearest hundreth.
First of all, we will draw a right triangle using our given information.
We know that sine relates opposite side of right triangle to hypotenuse.
We can see that side SR is hypotenuse and TS is opposite side to angle R.



Upon rounding to nearest hundredth, we will get:

Therefore, the value of the sine of ∠R is approximately 1.97.
