The response to claim A and Claim B on potential energy being stored in a magnet in terms of the given options is that;
Claim A; I think So
Claim B; Definitely Not
How to illustrate the claim?Claim A; This claim is true because If we move a magnet against the magnetic force of a stronger magnet, the motion will make the magnetic field lines to be compressed and this would lead to an increase in potential energy since the magnetic force lines will now be compressed.
Thus, the claim is correct that there is more potential energy that can be stored by moving against the magnetic force of a stronger magnet.
Claim B; Unlike claim A where the magnets were being moved from each other, in this case they are moved closer to each other and therefore this causes a greater compression of space which will lead to a loss in potential energy. Therefore this claim is not true.

Solve the equation: -8(2a-1)=36
-8.(2a - 1) = 36
-16a + 8 = 36
-16a = 36 - 8 = 28
a = 28/(-16) = -7/4
The correct answer is -7/4 = -1.75
The solution to the given equation is [tex]\frac{-7}{4}[/tex].

One number is 4 more than another and their sum is 60.
If x = the larger number and y = the smaller number, then which of the following is the value of the smaller number?
The larger number is 32 and the smaller number is 28 given that one number is 4 more than another and their sum is 60. This can be obtained by forming algebraic equation and finding
Calculate the value of the numbers:Given that one number is 4 more than another,
⇒x = y + 4 (equation (1))
Their sum is 60,
⇒x + y = 60
y + 4 + y = 60 (From (1))
2y + 4 = 60
2y = 56 ⇒ y = 28
x = y + 4 = 28 + 4 = 32
Hence the larger number is 32 and the smaller number is 28 given that one number is 4 more than another and their sum is 60.

In basic geometry, if two geometry objects intersect at right angles (90 degrees or π / 2 radians), they are vertical.
If two lines intersect at right angles, the line is perpendicular to another line. Explicitly (1) if two lines intersect, the first line is perpendicular to the second line. (2) At the intersection, the straight line angle on one side of the first line is cut by the second line into two congruent angles. Verticality can be shown as symmetric. That is, if the first line is perpendicular to the second line, then the second line is also perpendicular to the first line. Therefore, two straight lines can be said to be perpendicular (to each other) without specifying the order.

the slope-intercept form of the
equation for this line?
y= ~x-12
y= =x-4
y=~x+2
V= x+6
Answer: y = -x + 2
Step-by-step explanation:
Point slope form is y - y = m(x - x)
m = the slope of the line
Slope-intercept form is y = mx + b
m = the slope of the line
b = y-intercept
So because the - is in the m spot in the point-slope form, that means that is the slope of the line meaning it will also be in the m spot in slope-intercept form. The y-intercept of the line is found when x is 0. When we look at the two coordinates provided you can see that one of them shows when x is 0. We see that when x is 0, y is 2 which means that the y-intercept is 2.
So when you put the 2 in place of b, you get y = -x + 2

there's 12 red cards and 23 black cards

probability to pick a black card = 23/35
Answer: 23/35
Step-by-step explanation:
Probability is the measure of the likelihood of an event occurring. It is measured by the number of favorable outcomes over the total number of possible outcomes.
Here, the event is a black card being drawn. Since there are 12 + 23 = 35 cards in the deck, there are 35 possible outcomes of what card is picked. Out of those 35 cards, 23 are black, making 23 of the 35 options be the option we want.
23 black cards out of 35 total cards can also be written as [tex]\frac{23}{35}[/tex], which is the probability that a black card is chosen.

The volume of a cube is 36 cm3. What is the surface area of the cube, rounded to the nearest tenth of a cm2
Answer:
65.4 cm²
Step-by-step explanation:
The volume of a cuboid is calculated by multiplying the length, base, and height together. Since a cube has equal sides, the formula for the volume of a cuboid can be simplified as shown below.
Volume of cube
= side ×side ×side
= side³
Given that the volume is 36 cm³, let's find the length of each side.
side³= 36
Cube root both sides:
side=[tex]\sqrt[3]{36}[/tex]
Total surface area of a cube is the sum of the surface areas of its 6 identical square faces.
Area of a square
= side ×side
= side²
Surface area of 1 face= [tex](\sqrt[3]{36})^2[/tex]
Total surface area

Given that fruit punch calls for 333 liters of orange juice and 222 liters of pineapple juice and Jo creates a drink by mixing 444 liters of orange juice with 333 liters of pineapple juice.
In the Recipe for fruit punch calls
The Number of liters of orange juice = 333.
The Number of liters of pineapple juice = 222.
Thus, Total number of liters of juice = 222+333= 555 liters
Now, % of pineapple juice in fruit punch is
P₁=(222/555)×100
P₁=0.4×100
P₁=40%
Further, % of orange juice in fruit punch is
O₁=(333/555)×100
O₁=0.6×100
O₁=60%
In Jo's drink
The Number of liters of orange juice = 444.
The Number of liters of pineapple juice = 333.
Thus, Total number of liters of juice = 444+333= 777 liters
Now, % of pineapple juice in jo's drink is
P₂=(333/777)×100
P₂=0.43×100
P₂=43%
Further, % of orange juice in jo's drink is
