1000. You need to divide 1500 by 30 to get 50. Then you multiply that by 20. Please mark as brainliest!
Don't forget, for a whole number like the first term, the decimal point lies just to the right of the ones column. ... To subtract these numbers, first arrange the terms vertically, aligning the decimal points in each term. You can add zeroes to the right of the decimal point, to make it easier to align the columns
Answer:
63
Step-by-step explanation:
Use Pythagorean theorem,
base² + altitude² = hypotenuse²
a² + 9² = 12²
a² = 12² - 9²
a² = 144 - 81
a² = 63
a = √63
Answer:
c
Step-by-step explanation:
12/13=0.923 , and also sinb is ac/ab
<span>Let f(n) = 2n + 5. Then we must simply calculate (f1), f(2), ..., (f12). And we have that f(1) = 2*1 + 5 <=> f(1) = 7; f(2) = 2*2 + 5 <=> f(2) = 9; f(3) = 2*3 + 5 <=> f(3) = 11. And so on. It's easy to see that the rest of the results will be 13, 15, 17, 19, 21 and so on. So the summation will be S = 7 + 9 + 11 +... + 29 <=> S = 216</span>
