Answer:
V = PI*r^2 h/3
height= 3 * volume / (PI*radius^2)
Answer is B
Step-by-step explanation:
X = 19/3
________
________
The angle = 360° * 0.67 = 241.2
And by rounding to the nearest degree = 241°
The correct choice is number 4
Answer:
see below
Step-by-step explanation:
4.2 x 10^6 − 1.2 x 10^5 − 2.5 x 10^5
All exponent have to have the same number
42 x 10^5 − 1.2 x 10^5 − 2.5 x 10^5
Subtract the number
42 - 1.2 - 2.5 = 38.3
Add back the exponent
38.3 * 10 ^5
This is not in scientific notation
Move the decimal one place to the left and add one to the exponent
3.83 * 10^6
3.3 x 10^9 + 2.6 x 10^9 + 7.7 x 10^8
All exponent have to have the same number
3.3 x 10^9 + 2.6 x 10^9 + .77 x 10^9
Add the numbers
3.3+2.6+.77 =6.67
Add back the exponent
6.67*10^9
This is in scientific notation
8.0 x 10^4 − 3.4 x 10^4 − 1.2 x 10^3
All exponent have to have the same number
8.0 x 10^4 − 3.4 x 10^4 − .12 x 10^4
Subtract
8.0 - 3.4 - .12 = 4.48
Add back the exponent
4.48* 10^4
This is in scientific notation
4. 7/4 and 1 3/4
5. 5/2 and 2 1/2
6. 23/8 and 2 7/8
7. 2 1/10
2 1/2
1 8/9
1 8/11
1 3/4
8. 1 6/8 = 1 3/4
1 5/20 = 1 1/4
1 3/6 = 1 1/2
5 2/4 = 5 1/2
4 3/5
9. 21/8 = 2 5/8 pizza (idk if you need to round it to a whole number)
10. She can sell the material because she has 10.5 yds and it only requires 10 yds.
