6 is in the hundredths place
To round, look to the right of the number rounding up, if number is higher than 5, round up if its lower than 4, the number will remain the same.
Answer:
Powers of ten
Step-by-step explanation:
They are the result of multiplying 1= times iteself however many times.
The answer would be 177.4
2a) if 1 ft³ weighs 150 lb==>the TOTAL VOLUME =5,000/150 =33.334 ft³
2b) 1 ft³ 1,728 in³. So the TOTAL volume in in³ =33.334 x 1728 = 57,600 in³
c) Volume =(1/3)(πR²).H but R = H then V= (1/3)(πR³).plug V (=57600)
57,600 = 1/3 (πR³) ==> R³ = (3 x 57600) / π ==> R = 38 in
d) Area x thickness = Volume ==> Area x 2 in = 57600 in then:
Are =57600/2 & Area =28,800 in²
Supplementary angles
x+20+5x+10=180
6x+30=180
6x=150
x=25
