Answer:
The volume of ice cream will be <u>127 cm³</u>.
Step-by-step explanation:
Given:
Mary works at baskin Robbins. She is able to scoop perfectly spherical scoops of ice cream.
She gives you 2 scoops of ice cream that have a radius of 3 cm.
Now, to find the volume of 2 scoops of ice cream that have a radius of 3 cm.
As given in question the scoop is in spherical shape.
Radius ( r ) = 3 cm.
Putting the formula to get the volume:
Volume of sphere =
<em>Taking 3.14 as the value of π.</em>
Volume =
Volume =
Volume =
Volume =
There are 2 scoops of ice cream.
<em>So, the volume of 2 scoops </em>=
<u>Approximately = 127 cm³.</u>
Therefore, the volume of ice cream will be 127 cm³.
Short Answer:Choice C [Third one down]
RemarkStart with the number so I can talk about the basic principle at work. The way to work it is to factor 162 into prime factors and hope there are at least 3 that are the same.
162 = 2 * 81
162 = 2 * 3 * 3 * 3 * 3
Now When you take the cube root of that, you get
Here's the rule for a cube root. For every 3 prime factors under the cuberoot sign, you take out one and throw the other two away. So for cube root of 81,
you would factor it as ∛(81) = ∛(3 * 3 * 3 * 3) = 3∛3.
So out of four 3s under the cube root sign, you have 1 outside the root sign and one inside the root sign. 2 of the four 3s have been thrown away.
Continuation.X firstYou want 2 xs outside the root sign
∛(x * x * x * x * x *x ) = (x * x) You have thrown away 2 xs for every x outside the cube root sign
C = 6 There are no left overs.
Y secondFor the ys, you need 1 outside and 2 inside the root sign. that's because you need 5 altogether.
∛(y * y * y * y * y) = y ∛y^2
Answer c = 6; d = 2
Choice C <<<<<< answer
The answer is approximately 65minutes
Standard form: Ax + By = C where A, B, and C are integers.
(if you don't remember, integers are numbers like ...-2, -1, 0, 1, 2, 3...etc.)
Question 1
y+3=4(x-1)
Distribute the 4.
y+3=4x-4
Subtract 3 from the left.
y=4x-7
Subtract 4x from the right.
-4x+y=-7
multiply everything by -1 and make the x coefficient positive, it looks better
4x-y=7
y=1/4x-2
multiply everything by 4 to get rid of fractions
4y=x-8
subtract x
-x+4y=-8
multiply by -1
x-4y=8
y+2=2/3(x+4)
multiply by 3 to get rid of fractions
3y+6=2(x+4)
distribute
3y+6=2x+8
subtract 6
3y=2x+2
subtract 2x
-2x+3y=2
multiply by -1
2x-3y=-2
Answer:
D.$925
Step-by-step explanation:
$22 x 40 = $880
$880 + $45 =$925
