Answer:
it's 4
the reason it because in the graph 30 and so on are the same
<span>30 is 40% of 75 so it should be 45
</span>
40% = 0.4
Explication:
40 / 100 = 0.4
Answer is 9.5- explanation- if u substitute 9.5 in the equation 2(5 x 9.5+ 5 = so multiply 9.5 times 5 which equals 47.5 then multiply by the 2 which equals 95 plus the 2+3=5 - 95+5 equals 100 (sorry I’m bad at explaining)
Answer:
r = 28.28
Step-by-step explanation:
you already gave the equation: sin45°= 20/r
you wanna start by multiplying both sides by r. You do this so that your variable can be in the numerator and it will be easier to solve the equation:
r (sin45°) = 20
Now you divide both sides by sin45°, this will give you your final answer. For this, you have to put it in a calculator:
r = 28.28
P.S, good job on already knowing your equation... when i was learning this it took me a while to get eh hang of it :)
