Answer:
FORMULA USED-
NUMBER OF SUBSETS OF A SET WITH n ELEMENTS= 2^n
Here our set is { onions, garlic, carrots, brocoli, shrimp, mushrooms, zucchini, green pepper}
Different variations available for ordering pasta with tomato sauce= 28 = 256 ( As here n= 8)
Answer:
B -9/7
Step-by-step explanation:
We need to find a number between
-3 1/3 < x < -4/5
We want a number smaller than between -3 1/3 and -.8
Looking at the choices
-9/7 = - (7/7 + 2/7) = -(1+2/7) = -1 2/7
That is between -3 1/3 and -4/5
Sqrt(486) - sqrt(24) + sqrt(6)
find the factors of 486 that we can remove from under the square root sign
2 * 243
2 * 3 * 81
2 * 3 * 9 * 9 (we have 2 nines, we can move a 9 outside the sqrt sign)
sqrt(486) = 9 sqrt(6)
Repeating for sqrt(24)
2 * 12
2 * 2 * 6
2 * 2 * 2 * 3 (we can move a 2 outside the sqrt
sqrt(24) = 2 sqrt(6)
Finally, add all 3 terms together
9 sqrt(6) - 2 sqrt(6) + sqrt(6)
8 sqrt(6)
8 times square root of 6 is the final answer
Answer:32 cm2
Step-by-step explanation:Use the formula A=BH, The 7 does not count because it isn't base or height. Use 4 times 8 which will make 32 cm2.

Answer: 30 inches</h3>
==========================================================
Explanation:
x = unknown width
For this rectangle, there are 2 sides of length x, and 2 sides of length 17.
The perimeter is P = 2x+2*17 = 2x+34
Set this equal to the given perimeter (94) and solve for x.
2x+34 = 94
2x = 94-34
2x = 60
x = 60/2
x = 30
The TV is 30 inches wide
