Answer:
2x +2x=90
ZRQ
Step-by-step explanation:
FOR THE FIRST ONE, SUM OF ANGLES IN A TRIANGLE IS 180 AND SINCE WE KNOW ONE ANGLE IS 90° THE REST WOULD ADD UPTO 90°
THE SECOND ONE, JUST FOLLOW THE SEQUENCE OF THE MARKED LINES
for XYZ they went from the unlabeled line to the double marked line to the single marked line. similarly go for ZRQ
To round it with those numbers just round it to the nearest 1000, 10,000 and 100,000 and to know to round up or down is that if its 5 or up you round up and for down its 4 or less
10/3 = 3.33
3.45
sqrt 10 = 3.16
3 1/2 = 3.5
greatest to least : 3 1/2 , 3.45, 3.33, 3.16
Answer:
f(n) = 16(0.5)ⁿ⁻¹
Step-by-step explanation:
Find f(1) for each option.
a) f(1) = 16(0.5)¹⁻¹ = 16
b) f(1) = 32(0.5)¹⁻¹ = 32
c) f(1) = 16(0.5)¹ = 8
d) f(1) = 32(0.5)¹⁺¹ = 8
Only the first option matches the table.
Its 5 marbles because if she pulls twice as many red than blue, it means you divide in half so you get 5
Hope this helped :D
