show that (0.8a+0.4b)^2=(0.8a-0.4b)^2+1.28ab
please help me solve this asap
Step-by-step explanation:
first
(0.8a+0.4b)^2= (0.8a+0.4b) *(0.8a+0.4b)
=
0.64 a^2 + 0.32 ab +0.32ab + 0.16 b^2=
0.64 a^2 + 0.64ab + 0.16 b^2
second
(0.8a-0.4b)^2+1.28ab
= 0.64 a^2 - 0.64ab +0.16 b^2 + 1.28ab
= 0.64 a^2 + 0.64ab + 0.16 b^2
since the first (left parameters ) equals the second(right side parameters)

James went to the store to return a defective $45 tape recorder for a refund. At the same time, he bought some batteries for $3 per package. If he received $33 dollars of his refund, how many packages of batteries did he buy?
Answer:
4
Step-by-step explanation:
he should have gotten 45 back
but he only got 33
so the DIFFERENCE is how much he got in batteries, how many packs? well 45−33 = 12 12÷3=4
James bought 4 packages of batteries if James went to the store to return a defective $45 tape recorder for a refund. At the same time, he bought some batteries for $3 per package.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
James went to the store to return a defective $45 tape recorder for a refund. At the same time, he bought some batteries for $3 per package
Let he buy x number of packages of batteries.
The cost of packages of batteries = 3x
The linear equation one variable can be framed:
33 + 3x = 45
3x = 45 - 33
3x = 12
x = 4
Thus, James bought 4 packages of batteries if James went to the store to return a defective $45 tape recorder for a refund. At the same time, he bought some batteries for $3 per package.

The probability percentage that both players will be sophomores is 15.38%.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
We are Given that a football team has 4 freshman, 7 sophomores, 10 juniors, and 15 seniors, the following calculation must be done:
4 + 7 + 10 + 15 = 36
14/36= X
7/18 = X
0.38 = X
15/36= X
0.4 = X
0.4 x 0.38 = X
0.1538 = X
Thus, the probability that both players will be sophomores is 15.38%.

A trapezoid has a set of parallel bases with lengths 3 inches and 5 inches and a helght of 8 inches. What is the area
the trapezoid?
Answer:
The area of trapezoid is 32 inches^2
Step-by-step explanation:
Parallel base 1 = a = 3 inches
Parallel base 2 = b = 5 inches
Height of trapezoid = 8 inches
We need to find area of trapezoid
The formula used is: [tex]Area\:of\:trapezoid=\frac{a+b}{2}\times h[/tex]
Now putting the values and finding area of trapezoid
[tex]Area\:of\:trapezoid=\frac{a+b}{2}\times h\\Area\:of\:trapezoid=\frac{5+3}{2}\times 8\\Area\:of\:trapezoid=\frac{8}{2}\times 8\\Area\:of\:trapezoid=4\times 8\\Area\:of\:trapezoid=32[/tex]
So, the area of trapezoid is 32 inches^2

m is proportional to the cube of r. when r=3m,m=216.when r=5 find the value of m
Answer:
The value of m is 1000 for r=5
Step-by-step explanation:
Given that m is proportional to the cube of r
It can be written as:
[tex]m \propto\ r^3[/tex]
When the proportionality symbol is removed a proportionality constant is introduced in the equation.
Let k be the proportionality constant
[tex]m = kr^3[/tex]
Given
r=3,m=216
Putting the values
[tex]216 = k(3)^3\\216 = k * 27\\k = \frac{216}{27}\\k = 8[/tex]
The equation will now become
[tex]m = 8r^3[/tex]
Putting r = 5
[tex]m = 8(5)^3\\m = 8 * 125\\m = 1000[/tex]
Hence,
The value of m is 1000 for r=5

y = -4x + 15
-4x + 7y = 9
Answer: {y,x} = {3,3}
Step-by-step explanation:
1] y=-4x+15
[2] -4x+7y=9
Equations Simplified or Rearranged :
[1] y + 4x = 15
[2] 7y - 4x = 9
Graphic Representation of the Equations :
4x + y = 15 -4x + 7y = 9
Solve by Substitution :
// Solve equation [1] for the variable y
[1] y = -4x + 15
// Plug this in for variable y in equation [2]
[2] 7•(-4x+15) - 4x = 9
[2] - 32x = -96
// Solve equation [2] for the variable x
[2] 32x = 96
[2] x = 3
// By now we know this much :
y = -4x+15
x = 3
// Use the x value to solve for y
y = -4(3)+15 = 3
Solution :
{y,x} = {3,3}

7 + 10 + 5 = 22 total marbles.
Picking a blue one first would be 7 blue/22 total = 7/22
Picking a red one would be 5 red / 22 total = 5/22
Picking blue first and then red = 7/22 x 5/22 = 35/484

Curved surface area of a right circular cylinder is 44 m. If the radius of the base of the
cylinder is 0.7 m, find its height,
Answer:
The height of cylinder is 10 meters.
Step-by-step explanation:
Given
Curved Surface Area = 44m^2
Radius = r = 0.7 m
The curved surface area of a cylinder is given by:
[tex]CSA = 2\pi rh[/tex]
Putting the values we get
Pi can be taken as 22/7 or 3.14
We are taking 22/7 for the question
[tex]44 = 2 * \frac{22}{7} * 0.7 *h\\44 * \frac{7}{22} = 1.4h\\14 = 1.4h\\h=\frac{14}{1.4}\\h=10 m[/tex]
Hence,
The height of cylinder is 10 meters.
