Answer:
i couldnt see the first 2 good.
3. exact form= 58/15 decimal form= 3.86 mixed # form= 3 13/15
4. exact form= 13/8 decimal form = 1.625 mixed numbers 1 5/8
5.convert thw mixed number to improper fractions, then find the LCD and combine...-8
66.6667
20=x/100•30
Solve this equation and you will get your answer (66.6667)
(2x+3y)+(7x-3y)
First, group like terms together, so (2x+7x) + (3y-3y). Then simplify within the parentheses. 2x+7x = 9x and 3y-3y = 0, so you have 9x, which cannot be simplified any further. The answer is 9x.
Volume of a cone = pi * r² * (h/3)
If your diameter is 2, then take half of that for the radius; your radius is 1
Now plug in your given info:
V = pi * (1)² * (7/3)
= pi * 1 * (7/3)
= 7pi / 3
V ≈ 7.3304
Your answer is option D.
For lesson 4 10^15/10^4= 10^11 because when you are dividing with exponents you have to subtract the bottom exponent with the top one so 15-4=11; 10^15/10^4=10^11
