2x^2 + 7x + 3 ; you multiple each the terms in the first set or parentheses by the other
Answer:
A. (3.14)( 3) - (3.14)
Step-by-step explanation:
volume of the cone that can be filled with flavored ice = volume of cone - volume of the bubble gum
volume of cone = h
where r is the radius of the cone and h is its height.
volume of cone = x 3.14 x x 3
= 12.56 cube inches
volume of a sphere =
where r is the radius of the sphere.
radius =
=
radius = 0.25 inches
So that;
volume of the bubble gum = x 3.14 x
= 0.06542 cube inches
Thus,
volume of the cone that can be filled with flavored ice = 12.56 - 0.06542
= 12.49458
The volume of the cone that can be filled with flavored ice is 12.5 cube inches.
The answer to this question is n = 3
Answer:
x=1/4
y=1/2
Step-by-step explanation:
Given:
-2.4x+3.6y=1.2
2.4x + 1.2y=1.2
-2.4x+3.6y=1.2
Divide through by 1.2
-2x+3y=1
2.4x + 1.2y=1.2
Divide through by 1.2
2x+y=1
-2x+3y=1 (1)
2x+y=1 (2)
From 2
y=1-2x
Substitute y=1-2x into (1)
-2x+3y=1
-2x+3(1-2x)=1
-2x+3-6x=1
-8x=1-3
-8x=-2
Divide both sides by -8
x=1/4
Substitute x=1/4 into (2)
2x+y=1
2(1/4)+y=1
2/4+y=1
1/2+y=1
y=1-1/2
y=1/2
x=1/4
y=1/2
If the force between two charged objects when you triple the magnitude of both charges. The Force will become 9 times the initial force.
<h3>What is coulombs law?</h3>
According to coulombs law force between two charges is given by
Here, R is the distance between both the charges Q and q.
Let the force on the charges be F1
The distance of separation = r
The magnitudes of the charges q1 and q2
K = Coulumb's constant
Let the force on the charges be F
The distance of separation = r
The magnitudes of the charges 3q1 and 3q2
K = Coulumb's constant
So,
