Answer:
V = 1436.76
Step-by-step explanation:
<u>Formula:</u>
V = 4/3πr³
<u>Given:</u>
r = 7
<u>Work:</u>
V = 4/3πr³
V = 4/3π(7³)
V = 4/3π(343)
V = 1436.76
Answer:
y=11/3
Step-by-step explanation:
3y=2+9
Divide both sides by 3.
3y/3 = (2+9)/3
y=2/3+9/3
Combine like terms.
<u>y=11/3</u>
Answer:
Step-by-step explanation:
Let the total budget be x.
<u>Given condition:</u>
73% of total budget = 949
73% of x = 949
<u>Key:</u>
of => to multiply
% => out of 100
<u>Solution;</u>
![\displaystyle \frac{73}{100} \times x = 949\\\\Multiply \ \frac{100}{73} \ to \ both\ sides\\\\x=949 \times \frac{100}{73} \\\\x = \frac{94900}{73} \\\\x = \$ 1300\\\\\rule[225]{225}{2}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7B73%7D%7B100%7D%20%5Ctimes%20x%20%3D%20949%5C%5C%5C%5CMultiply%20%5C%20%5Cfrac%7B100%7D%7B73%7D%20%5C%20to%20%5C%20both%5C%20sides%5C%5C%5C%5Cx%3D949%20%5Ctimes%20%5Cfrac%7B100%7D%7B73%7D%20%5C%5C%5C%5Cx%20%3D%20%5Cfrac%7B94900%7D%7B73%7D%20%5C%5C%5C%5Cx%20%3D%20%5C%24%201300%5C%5C%5C%5C%5Crule%5B225%5D%7B225%7D%7B2%7D)
Answer:
4 hours. 1 3/4 is about 2, and 2 1/4 rounds to 2. 1/4 would round to 0, but it would not affect the estimate's accuracy much because we rounded up by 1/4 on 1 3/4 already. Philipe spent about 4 hours on activities.
Step-by-step explanation:
I think estimation is terrible. If u want to truly solve it, you just need to get a common denominator on each of the fractions. that means the bottom half of both fractions must be the same in addition or subtraction. so here, the common denominator would be 66. What times 6 = 66? 11. So 1*11/6*11 = 11/66. Then what times 11 = 66? 6. So 6*6/6*11.
Your new problem is 2 11/66 + 3 36/66. Now you can just add it up, but the denominators will always stay the same, 66. Your answer would be 5 47/66
