68. add the two measures then subtract from 180.
Answer: f(0) = 5.5 f(2) = 3.7
<u>Step-by-step explanation:</u>
When x = 0, f(x) = 5.5 <em>In other words, f(0) = 5.5</em>
When x = 2, f(x) = 3.7 <em>In other words, f(2) = 3.7</em>
Writing this problem in symbols instead of in words greatly simplifies it:
(2 2/3) * (1 1/5) * (1 1/2)
Write each quantity (inside each set of parentheses) as an improper fraction:
(8/3) * (6/5) * (3/2)
Now multiply the numerators thru: 8*6*3 / 3*5*2
Notice that we can reduce this by dividing the 8 by the 2 and dividing the 6 by the 3: 4*3*3 36
---------- = -----------

ans=26.92
use trigonometric ratios
a²= b²+c²
a²=25²+10²
a²=625+100
now take square root on both sides
a
a=26.92
a=27 (2decimal place)
Answer:
3
Step-by-step explanation:
Since the shelves are 75.5cm long, the total length she would be needing is 75.5cm × 6 = 453cm
Now, the length of the wood she is using is 180cm, to get enough length to make the shelves, we would need to divide 453cm by 180cm which gives a value of around 2.51
This is approximately equal to 3 when rounded up to the nearest whole number.
