To calculate the sine of an angle, simply divide the length of the opposite side, 479.16, by the length of the hypotenuse, 610. To get the cosine, divide the length of the adjacent side, 377.5, by the length of the hypotenuse, 610.
Answer: A is 32.5
B is 162.5
Step-by-step explanation:
so what i did was that i divided 65/13 and i got 5 and then i divided 5/2 and got 2.5 and then i multiplied 13 and 2.5 and got 32.5 and then i divided 32.5 and 2.5 and got 65 and then i multiplied 65 and 2.5 and got 162.5
hope that helped!
good luck :)
This kinda sounds like system of equations to me. Let's use some variables. 'x' would be the fee for the regular selections. 'y' would be the fee for the discounted selections. Let's start making our equations :O. Here's Pat's order: 2x+4y=119.80. Here's Carlos' order: 3x+5y=160.75. Now, there are different ways of solving these variables such as using substitution, but I will use linear combinations method/elimination method to solve this. I will try to make one variable value the opposite of the other equation's variable. I can get 6x+10y=321.50 and -6x-12y=-359.4. I can eliminate the x now and only have variable y. -2y=-37.9. Dividing both sides gets me y=18.95. I can substitute the y value for y in any equation. so 2x+4(18.95)=119.80. 2x+75.8=119.80. 2x=44. 2x/2=44/2. x=22. Therefore, the fee for regular selections is 22 while the fee for discounted selections is 18.95. Hope you enjoyed this session of learning :3
Answer:
$7282.8
Step-by-step explanation:
You multiply 7000*0.02
Add 140 (answer to this^) to 7000
7140*0.02
^add this answer to get 7282.8
42.43 you would just square root it by typing in 1800 then hitting the radical sign. Hope this helped
