A party store sells large plates in packs of 12 and small plates in packs of 8 . In order to have an equal number of both , what is the least amount of large plants that would have to be purchased

Answers

Answer 1
In order to have the least amount of each, you would need to purchase 2 packages of large plates.  Here is the reasoning:

You can buy the following number of large plates and small plates:

Small:  8, 16, 24, 32, ...
Large:  12, 24, 36, ...

The smallest number that can be bought so you have an equal amount is 24 of each.

To get 24 large plates, you would need 2 packages.

What is linear equation?

Each term in a linear equation has an exponent of 1, and when this algebraic equation is graphed, it always produces a straight line. It is called a "linear equation" for this reason.

Both linear equations with one variable and those with two variables exist.

Given equation -9x(5 - 2x)

product  = -9x(5) - (-9x)(2x)

= -45x + 18x²

= 18x² - 45x

Hence the product is 18x² - 45x.

How does the volume of an oblique cylinder change if the radius is reduced to 2/9 of its original size and the height is quadrupled?

A. V=2/81pir^2h
B. V=16/81pir^2h
C. V=4/9pir^2h
D. V=16/9pir^2h

Answers

New volume is given by:
New volume=(old volume)×(4×2/9×2/9)
simplifying the above we get:
New volume=(old volume)×16/81
Thus the new volume is 16/81 times the old volume
old volume=πr²h

a ball is thrown with a slingshot at a velocity of 100 ft/sec at an angle 21 above the ground from a height of 5ft approximately how long does it take for the ball to hit the ground? acceleration due to gravity is 32 ft/s^2

Answers

It takes approximately 6.3 seconds to hit the ground.

We use the equation h(t)=-1/2gt²+v₀t+h₀ to set this up.  g is the acceleration due to gravity, v₀ is the initial velocity and h₀ is the initial height:
h(t) = -1/2(32)t² + 100t + 5
h(t) = -16t² + 100t + 5

We will use the quadratic formula to solve this:
[tex]t=\frac{-b\pm\sqrt{b^2-4ac}}{2a} \\ \\=\frac{-100\pm\sqrt{100^2-4(-16)(5)}}{2(-16)} \\ \\=\frac{-100\pm\sqrt{10000--320}}{-32} \\ \\=\frac{-100\pm\sqrt{10320}}{-32} \\ \\=\frac{-100\pm101.59}{-32} \\ \\=\frac{-100+101.59}{-32}\text{ or }\frac{-100-101.59}{-32} \\ \\=\frac{1.59}{-32}\text{ or }\frac{-201.59}{-32} \\ \\=-0.05\text{ or }6.3[/tex]

The probability that the first ball is red: [tex]P(R)=\dfrac{10}{16}=\dfrac{5}{8}[/tex]
The probability that the second ball is black: [tex]P(B)=\dfrac{1}{15}[/tex]
Together:[tex]P(R)\cdot P(B)=\dfrac{5}{8}\cdot\dfrac{1}{15}=\dfrac{1}{24}[/tex]

10 + 5 + 1 is 16. There are 10 red balls, and there are 16 balls altogether. If you’re asking for a fraction, it would be 10/16. 10/16 as a simplified fraction is 5/8. The probability that the first ball is red is 5/8. There is one black ball, and 16 altogether. If you’re asking for a fraction, it would be 1/16. 1/16 can’t be simplified anymore because it is already in its lowest terms. So the probability of drawing out a black ball is 1/16.
So your answers are....

First ball being red: 5/8

Second ball being black: 1/16

Divide 2y2 + 8 by 2y + 4. Which expression represents the quotient and remainder?



Answers

Final answer:

To divide 2y² + 8 by 2y + 4, use long division to find the quotient and remainder.

Explanation:

To divide 2y² + 8 by 2y + 4, we can use long division. Here are the steps:

Divide the first term of the dividend by the first term of the divisor, which gives us y.

Multiply the entire divisor by y to get 2y² + 4y.

Subtract 2y² + 4y from the dividend 2y² + 8 to get 4.

Next, divide 4 by 2y + 4, which gives us 2.

Finally, we have a remainder of 0.

Therefore, the quotient is y + 2 and the remainder is 0.

How do you complete the square of x^2-14x+33=0?

Answers

x² - 14x + 33 = 0 is in the form ax² + bx + c = 0. We will need this for the second step.

Subtract 33 from both sides
x² - 14x = - 33

Divide the b term by 2 and then square the result. Then add that to both sides.
- 14 / 2 is - 7. (- 7)² = 49. Add that to both sides

x² - 14x + 49 = - 33 + 49

Combine the constants and factor the trinomial
(x - 7)² = 16

Square root both sides
x - 7 = +/- 4
or
x - 7 = - 4 and x - 7 = 4

You have to place a plus-minus statement because (- 4)² and 4² both equal 16. 

Now we solve for x in each equation. Add 7 to both sides to isolate our variable.
x = 3 and x = 11

Final answer:

To complete the square for the equation x^2-14x+33=0, the constant 33 is moved to the other side, and the number needed to make the left side a perfect square trinomial, 49, is added to both sides, resulting in factoring and solving (x - 7)^2 = 16 to find x = 11 and x = 3.

Explanation:

To complete the square for the equation x^2-14x+33=0, you need to form a perfect square trinomial on the left side of the equation. First, you'll move the constant term to the right side:

x^2 - 14x = -33

Next, find the value that completes the square for the x-terms. This value is obtained by taking half of the coefficient of x (which is -14 in this case) and squaring it, giving us (-7)^2 = 49.

Add 49 to both sides of the equation:

x^2 - 14x + 49 = -33 + 49

x^2 - 14x + 49 = 16

Now, the left side of the equation is a perfect square trinomial, and can be factored into:

(x - 7)^2 = 16

To solve for x, take the square root of both sides:

x - 7 = [tex]\sqrt{16}[/tex]

x - 7 = +- 4

Finally, solve for x by adding 7 to both sides:

x = 7 +- 4

x = 11 or x = 3

katy buys ‘x’ cakes.
Gugu buys 3 times as many cakes as katy.
Deanna buys 2 more cakes than Katy.

Each cake costs 85p
The total of the cakes is £52.70

How many cakes did each girl buy?

Answers

Answers:
Katy bought 12 cakes
Gugu bought 36 cakes
Deanna bought 14 cakes

Explanation:
We are given that:
Katy bought x cakes 
Gugu bought 3 times as many as Katy. This means that Gugu bought 3x cakes
Deanna bought 2 cakes more than Katy. This means that Deanna bought x+2 cakes

Total number of cakes bought = x + 3x + x + 2 = 5x + 2 cakes

We know that the price of each cake is 85 p = £0.85 and that the total amount paid is £52.7
This means that:
(5x+2)(0.85) = 52.7
4.25x + 1.7 = 52.7
4.25x = 52.7 - 1.7
4.25x = 51
x = 51 / 4.25
x = 12

Now, we will get the number of cakes that each bought as follows:
Katy bought x cakes = 12 cakes
Gugu bought 3x cakes = 3(12) = 36 cakes
Deanna bought x+2 cakes = 12 + 2 = 14 cakes

solve the equation
3x-3= -18

Answers

Alright! So the first step to solving 3x-3=-18 is isolating the variable. In other words, you want to make sure x is all by itself on one side of the equal sign.

3x-3=-18
   +3   +3  Remember: What you do to one side, you have to do to the other.
3x = -15

Now divide by the coefficient (the number in front of x).

(3x)/3 = (-15)/3
x = -5

The solution of the  equation 3x-3= -18 is  -5.

The  algebraic expressions which are separated by an equal symbol  in between them and with the same value is called is an equation

Example = 5x + 5 = 12

here, x is a variable and 5 and 12 are constants.

Given equation;

3x-3= -18

To find the value of x add 3 to both side, we get

3x = -18 +3

we get

3x = -15

divide both side by 3 we get

[tex]x = \dfrac{-15}{3}[/tex]

Convert in into the lowest form we get,

x = -5

The solution of the  equation 3x-3= -18 is  -5

Then you have to multiply 16 by the height. I'm not sure what the height is because you never gave me one but hopefully this helped! God bless :)

P=2(4x+(x+6))
P=2(4x+x+6)
P=2(5x+6)
P=(10x+12)
