HELP PLEASEEEE!!The math team decided to sell customized pocket protectors as a
fundraiser. These were truly a hot item in our school, and $240 was
raised. Cecily had originally suggested a price that was $2 lower
for each item, but if the team had agreed to that price they would have
had to sell 20 more pocket protectors to get the $240.
How many pocket protectors did they actually sell? What was the price of
each?

If the perimeter of a right triangle is 42 units and the length of the hypotenuse is 20 units, find the length of the other two sides of the triangle.Can you please show work

Answers

so
a^2+b^2=c^2
c=hypotenuse
a^2+b^2=20^2=400

if the permiter is 42 then
p=hypotonuse+side+side
42=20+side+side
subtract 20 from both sides
22=side+side

a+b=22
subtract b from both sides
a=22-b
subsitute for a in equation below
a+2+b^2=c^2
(22-b)^2+b^2=400
b^2-44x+484+b^2=400
2b^2-44x+484=400
divide both sides by 2
b^2-22x+242=200
subtract 200 from both sides
b^2-22x+42=0
factor
(b+/-number)(b+/-number)
to find the numbers, find which 2 number multiply to 42 and add to get -22
the numbers must be neative since same signs multiplied=positive and negative+negative=negative
(b-number)(b-number)
facrors of 42=2,3,6,7,14,21
2,21
3,14
6,7
it's hard to find the number, but the numbers are -19.8882 and -2.11181
(b-19.8882)(b-2.11181)=0
if xy=0 then assume that x and y=0

b-19.8882=0
add 19.8882 to both sides
b=19.8882

b-2.11181=0
add 2.11181 to both sides
b=2.11181

the side legnths are 19.8882 units and 2.11181 units

What is trigonometry?

The branch of mathematics that sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry.

The trigonometric functions, also known as circular, angle, or goniometric functions in mathematics, are real functions that link the angle of a right-angled triangle to the ratios of its two side lengths.

Use the sin angle ratio and calculate,

Sine = Opposite / Hypotenuse

sin 60° = a / (6√3) But sin60° = √3/2

√3/2 = a/(6√3)

Cross multiply

2 x a = 6√3 x √3

2a = 6 x √(3 x 3)

2a = 6 x 3

a = 6 x 3/2

a = 3 x 3 = 9

Therefore, the length of the altitude of the equilateral triangle is 9 units.

Using Sine.

Sine = Opposite / Hypotenuse

sin 60° = a / (6√3) But sin60° = √3/2

√3/2 = a/(6√3)

Cross multiply

2*a = 6√3 * √3

2a = 6 * √(3*3)

2a = 6*3

a = 6*3/2

a = 3*3 = 9

Option E.

Please, help me! A farm producing x tons of rice at a cost represented by C = 3x +3. If the total revenue from rice production is given by R = 7x + 2, to not have prejudice, the farm must produce at least:

Answers

Profit = Revenue – Cost

To reach a point of breakeven, Profit = 0.

Therefore,

Revenue = Cost

7x + 2 = 3x + 3

x = ¼

therefore the farm must produce at least ¼ tons of rice so that there will be no loss.

Please ,   Not delete my answer, because is correct.

It is false that any three points are containded in exactly one plane.

For example: if the points are aligned, these points aren´t containded in a plane, these points are containded in a line.
