Solve for x.
x/p³=1
NO ANSWERS CONTAINING CURSE WORDS OR YOU GET REPORTED!!!!!!!!!!!!!!
Answer:
Since x/p³ = 1 we can multiply the equation by p³ so x = p³.
Answer:
[tex]$\frac{x}{p^3}=1$[/tex]
Multiply both sides by [tex]p^3[/tex]
[tex]x=p^3[/tex]
and [tex]p^3 \neq 0[/tex] otherwise, it is undefined.

Which of the following sets could be the sides of a right triangle?
{2,3, square root 13} {2,2,4}{1,3, square root 3}
Answer: 2, 3, square root 13
Step-by-step explanation:
Use the Pythagorean Theorem (a^2 + b^2 = c^2)
2^2 = 4
3^2 = 9
4 + 9 = 13
Square root of 13 is c
Answer:
2,3,[tex]\sqrt{13}[/tex]
Step-by-step explanation:
The first choice:
2, 3, [tex]\sqrt{13}[/tex]
Pythagorean theorem states that for a right-triangle of sides a,b and c where c is the hypotenuse; a² + b² = c²
So the hypotunese has to be the longest side of all.
The longest side in this case is [tex]\sqrt{13}[/tex]
So, 2² + 3² must be equal to ([tex]\sqrt{13}[/tex])²
Let's check if its true ...
2² + 3² = ([tex]\sqrt{13}[/tex])²
4 + 9 = 13
13 = 13
Right! Sides 2, 3, [tex]\sqrt{13}[/tex] are sides of a right triangle.
There is no need to check the other sets.What is the volume of the following rectangular prism?

Answer:
320 ft²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = [tex]\frac{1}{2}[/tex] h (a + b)
where h is the perpendicular height and a, b are the parallel bases
Here h = 16, a = 18 and b = 12 , thus
A = [tex]\frac{1}{2}[/tex] × 16 × (18 + 12) = 8 × 40 = 320 ft²

What is Inequality?A relation by which we can compare two or more mathematical expression is called an inequality.
Given that;
Mrs. Sloane has $500 to buy a video game console and some video games for her family.
And, Including tax, the video game console costs $280, and a video game costs $25.
Now, Let the maximum number of video games = x
Hence, We can formulate;
⇒ 25x + 280 ≤ 500
⇒ 25x ≤ 500 - 280
⇒ 25x ≤ 220
⇒ x ≤ 8.8
Hence, The maximum number of video games Mrs. Sloane can buy is,

Rajesh is working out the area of a circle with radius 10.
he writes:
area = 3.142 x 20
explain why Rajesh's workings are wrong?
Answer:
Rajesh applied the wrong formula
Step-by-step explanation:
The problem is on mensuration of flat shapes, circles.Rajesh applied the wrong formula for the calculation of the area of a circle
he used [tex]area= \pi d[/tex]
Rajesh is expected to solve for the area of a circle using the right formula, which is
[tex]area= \frac{ \pi d^{2}}{4} \\or\\area= \pi r^{2}[/tex]
substituting our data we have

The system of equations
(xy)/(x+y)=1, (xz)/(x+z)=2, (yz)/(y+z)=3 has exactly one solution. What is $z$ in this solution?
Answer:
z = -12
Step-by-step explanation:
Rewritting the equations, we have:
x + y = xy (eq1)
2x + 2z = xz (eq2)
3y + 3z = yz (eq3)
From the first equation:
x = y/(y-1) (eq4)
From the third equation:
y = 3z/(z - 3) (eq5)
Using the value of y from (eq5) in (eq4), we have:
x = [3z/(z - 3)] / [3z/(z - 3) - 1]
x = [3z/(z - 3)] / [(3z - z + 3)/(z - 3)]
x = 3z / (2z + 3) (eq6)
Using the value of x from (eq6) in (eq2), we have:
6z / (2z + 3) + 2z = (3z / (2z + 3))*z
(6z + 4z^2 + 6z) / (2z + 3) = 3z^2 / (2z + 3)
12z + 4z^2 = 3z^2
z^2 = -12z
z = -12
Riley is saving up to buy a new television. She needs a total of $1,008.30. Riley has saved $200.80 already and earns $80.75 per week at her job. How many weeks does Riley need to work to save enough money to buy the new television?
Answer: 10 weeks
Step-by-step explanation:
Cos of television = 1008.30
Savings = 200.80
Balance = 1008.30 - 200.80 = 807.50
She needs to work 807.50/80.75 = 10 weeks
Arjun is twice as old as Shreya. If five years ago his age was three times Shreya's age, then Arjun's present age is
Answer:
Arjun is 20 years old and Shreya is 10 years old.
Step-by-step explanation:
5 YEARS AGO-
Arjun: 2x-5
Shreya: x-5
NOW-
Arjun: 2x
Shreya: x
EQUATION-
2x-5=3(x-5) = 2x-5=3x-15
(add 15 on both sides)
2x+10=3x
(subract 2x from both sides)
x=10
Therefore, Arjun is 20 years old and Shreya is 10 years old :)

The length of a rectangle is twice its width. The perimeter of the rectangle is 156 feet. What is the length and the width of the rectangle?
Answer:
Length = 26, Width = 52
Step-by-step explanation:
156/6 = 26
26*2=52
Answer: The length will be 52 and the width will be 26
Step-by-step explanation:
If the formular to calculate Perimeter of a rectangle is
P = 2* (L+W)
and the length L= 2W.
156 = 2* (2W+ W)
156 = 2* (3W)
156 = 6W
Solving for W
W= 26
Since in the question the Length L is 2* W(width)
L= 2* 26 = 52

Encouraged by his investment, Joseph decides to open another CD account. This time, he deposits $1,000 and plans to leave it
untouched for 3 years. In exchange, the bank will pay him 0.3% interest every month. How much will be in the account when the 3
years have passed?
Answer:
Joseph will have 1,108$ in his bank account when he opens it again.
First, we need to know how much 0.3% of 1000$ is, which is 3$.
Next, since there are 12 months in a year we multiply 3$ by 12 which is 36.
Then, since 3 years have passed we multiply 36$ by 3 which is 108$. So in conclusion, he'll have 1,108$ when he checks his account again.
Answer:
$1,113.87
Step-by-step explanation:
The initial value is 1,000, the rate of increase is 1.003, and the number of times it will increase is 36. y=1000 ( 1.003 ) 36 =1,113.87y equals 1000 left parenthesis 1.003 right parenthesis superscript 36 baseline equals 1113.87.
