I’ll make it easier, so for number 2 on number 6 7/8 times 8 and 6 and you have 48, then add the top number which would be 55. Then for the second number, 4 1/3 do the same thing! 4*3= 12+1= 13 then add 13+55 and your answer is 68! Then put it in fraction form! 17/25, then all you do is simplify it! If it can’t be simplified (17/25 can not be simplified), it stays the same. Hope that helps! :)
Answer:
0.00466
Step-by-step explanation:
8+7+10+6 = 31
(8C2×7C3×10C4×6C5) ÷ 31C14
= 0.004656415426
= 0.00466 (3 sf)
A. 10.3 ft^2 should be the right answer
Answer:
22.1°
Step-by-step explanation:
cos^-1(x) = (8² - 19² - 14²) ÷ -2(14)(19)
cos^-1(x) = -493 ÷ -532
cos^-1(0.9267) = 22.1°
