$18.00 if you move the decimal one place to the left 10% tip would be $1.80,
multiply $1.80 x 2 = $3.60 which is 20% for the tip.
$18.00 + $3.60 = $21.60 divide by 4 people = $5.40 per person
If the pyramid fits perfectly in a cube, this means that its base is a square and its height has the same value as the side of the square. Let x be the measure of the sides of the cube. The volume of the cube (Vc),
Vc = x³ ; 49 ft³ = x³ ; x = 49^(1/3)
The volume of the pyramid is,
Vp = (1/3)(x²)(x) = (1/3)(x³)
Substituting the known values,
Vp = (1/3)((49^(1/3))³ = 16 1/3 ft³
Thus, the volume of the pyramid is approximately 16.33 ft³.
15 pounds of peanuts cost 45 dollars
how much does 1 pound of peanuts cost
ok
15 times (cost per pound)=45
represent cost per pound with 'w'
15 times w=45
15w=45
divide both sides by 15
w=45/15
w=3
cost is $3 per pound
Answer:
B 2.25
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
The mean will be the very middle of the distribution, which is at 66. So we know that a and c are wrong.
The standard deviation is the distance between those bars, like 70 and 74. 74-70 = 4, so the standard deviation is probably around 4.
That means the answer is D.
