You have an allowance of $12.00. You buy a discount movies ticket that costs at least $3.50 and popcorn that costs $2.75. HOw much do much do you have for other spending?

Answer:

$120

Step-by-step explanation:

First add the 10% back, to do so make it a decimal by moving the . over to the left twice.

Now setup the equation OP= New price/(1-discount)

91.80/(1-.10)=102

So the price before the 10% discount is $102

Now set it up again with the new numbers.

102/(1-.15)=120

So the original price before all discounts was $120

*Let p = original price

So firstly, how would we get the price when it's 15% off? You would find multiply the price by 0.15 (15% in decimal form) and then subtract the product from the original price. This can be represented as [tex](p-p\times0.15)[/tex]

Next, we would have to use the 10% off when the dress is already 15% off. The process is similar: Multiply 0.10 (10% in decimal form) with 15% off dress, then subtract the product from the 15% off price. This can be represented as [tex](p-p\times0.15)-0.10(p-p\times0.15)[/tex]

Now since the price is equal to $91.80, we would equal the prior expression to 91.80 as such: [tex](p-p\times0.15)-0.10(p-p\times0.15)=91.80[/tex] From here we can solve for p.

Firstly, solve the multiplication inside of the parentheses:

[tex](p-0.15p)-0.10(p-0.15p)=91.80[/tex]

Next, distribute -0.10 to (p - 0.15p):

[tex]p-0.15p-0.10p+0.015p=91.80[/tex]

Next, combine like terms:

[tex]0.765p=91.80[/tex]

Lastly, divide both sides by 0.765:

[tex]p=120[/tex]

The original price of the dress was $120.

a) Container z: 22 liters. b) Container x has 18 liters more than container z.

To solve this problem, let's first find the volumes of water in containers x, y, and z.

Let's represent the volume of water in container x as 5x liters and the volume of water in container y as 2x liters, based on the ratio given.

Then, according to the ratio of y to z, if the volume of water in container y is 2x, the volume of water in container z is (11/8) × 2x liters.

Now, we can set up an equation to find the value of x.

5x (container x) + 2x (container y) + (11/8 × 2x) (container z) = 78 liters

5x + 2x + (11/8 × 2x) = 78

5x + 2x + (11/4 × x) = 78

Multiplying through by 4 to clear the fraction:

20x + 8x + 11x = 312

39x = 312

x = 312 / 39

x = 8

Now, we can find the volumes of water in each container:

Container x = 5x = 5 × 8 = 40 liters

Container y = 2x = 2 × 8 = 16 liters

Container z = (11/8) × 2x = (11/8) × 16 = 22 liters

a) The amount of water poured into container s (assuming it was meant instead of "s" since "s" wasn't mentioned in the problem) is the volume of water in container z, which is 22 liters.

b) The difference in the amount of water poured into containers x and z:

Volume in container x - Volume in container z = 40 liters - 22 liters = 18 liters.

So, 22 liters of water was poured into container s, and 18 liters more water was poured into container x than into container z.

2xa + 2xbc (just multiply both units in the paranthesis by whats on the outside.)

(a + bc)2x

= 2x*a + bc*2x

= 2ax + 2bcx

The value of x will change because that is the price of the almonds

Therefore mx will change

And the value of mx+b will decrease because the price is cheaper

Answer:

The correct statements are :

1. The value of mx will change.

2. The value of m will change.

3. The value of mx+b will decrease.

Step-by-step explanation:

Todd needs x ounces of almonds, which are priced at m dollars per ounce in the baking section. So, price of x ounces becomes = mx

The total cost of the other ingredients is b dollars.

Hence, total cost is given as = [tex]mx+b[/tex]

Now, Todd later finds almonds in the bulk section that are half the price of those in the baking section.

So, now price is :[tex]\frac{m}{2}[/tex]

And total price for 'x' ounce will become: [tex]\frac{mx}{2}+b[/tex] dollars.

Therefore, if Todd purchases the almonds in the bulk section, the total cost  will decrease.

The correct statements are :

1. The value of mx will change.

2. The value of m will change.

3. The value of mx+b will decrease.

Step-by-step explanation:

I would say

(x+5)(x-5)(x+5i)(x-5i)

The factor of the expression x⁴ + 10x² + 25 is (x + √5i)(x - √5i) after using the factor method.

It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.

It is given that:

The expression is:

= x⁴ + 10x² + 25

Let t = x²

= t² + 10t + 25

= (t + 5)²

= (x² + 5)²

x² = -5

x = ±√5i

(x + √5i)(x - √5i)

Thus, the factor of the expression x⁴ + 10x² + 25 is (x + √5i)(x - √5i) after using the factor method.

- The rungs are perpendicular to the other side.

Answer:

The rungs are perpendicular to the other side.

Step-by-step explanation:

Given

The sides of ladder are parallel.Rungs is perpendicular to one side of the ladder.

Let [tex]a\parallel b[/tex]

[tex]a\perp c[/tex]

When two lines are parallel then the slopes of two lines are equal.

We can say [tex]m_1=m_2[/tex]

Where [tex]m_1[/tex]= slope of line a( side of ladder)

[tex]m_2[/tex]= solpe of line b( side of ladder)

When two lines are perpendicular then slopes of two lines are opposite reciprocal to each other.

We can say [tex]m_2=-\frac{1}{m_3}[/tex]

Where [tex]m_2[/tex]= Slope of line b

[tex]m_3 [/tex]=Slope of line c (rung)

By transitive property of equality we get

[tex]m_1=-\frac{1}{m_3}[/tex]

Hence, the slope of side of ladder  a and rung  c are opposite reciprocal to each other.Therefore , the rungs are perpendicular to the other side.

Answer:

10 years.

Step-by-step explanation:

Let Jerome, Keenan, and Leitha have ages of x,y and z respectively,.

Then given that x+y =18  ... i

                           x+z =19  ... ii

                           y+z = 21 ... iii

From the above information we are to find out y and i.e.Keenan age.

Add all the 3 equations

Left side becomes x+y+y+z+z+x = 2(x+y+z)

and right side becomes = 18+19+21 = 58

In other words, 2(x+y+z) = 58

Divide by 2

x+y+z =29  ... iv

From the equation iv subtract ii

x+z =19

We get y = 10

Hence Kennan age = 10 years

Have all the terms containing the variable on one side of the equation and the rest of the terms on the other side of the equation.

I will put all terms containing the variable b on the left side of the equation and the rest on the right side of the equation.

Subtract 8b from both sides of the equation.

-9 -12b = 3

Add 9 to both sides of the equation to isolate the term with the variable b.

-12b = 12

Divide both sides of the equation by -12 to solve for b.

b = -1

Answer:

1. Take a=4, b=6

a+b

=4+6

=10( Both are positive integers)

2.  a=4 , b= -6

then 4 + (- 6)

= 4 - 6

= -2 [Smaller is positive integer and larger is negative integer , So subtract smaller from larger and apply the sign possessed by larger integer]

3. a = -4, b= -6

a+ b

= -4 -6

=-10 [ Both are negative integers add them apply - sign before the number.]

4. a = -4, b=6

a +b

= -4+ 6

= 2 [one is positive and other is negative subtract smaller from larger and apply positive sign before the number.]

Choice A: x^2−2x+4− 15/x+2

Step-by-step explanation:

The result of the division of the cubic polynomial x^3-7 by the binomial [tex]x+2 is x^2-2x+4 - 15/(x+2)[/tex], as obtained by carrying out the process of polynomial division.

The student is asking for the result of dividing a cubic polynomial, x^3-7, by a binomial, x+2. To do this, we need to perform polynomial division. The result of this division is [tex]x^2-2x+4 - 15/(x+2)[/tex]. We get this by setting up and performing the division, which operates similarly to long division, except that you are working with polynomials instead of numbers. The steps involved are too complicated to list here, but involve repeatedly subtracting multiples of x+2 from x^3-7 until the remainder is less than x+2, at which point you can't subtract more multiples of x+2.

The hottest temperature ever recorded on Earth was 134°F in Death Valley, California. If you were to multiply this temperature by 13.46, then the result would not provide a realistic temperature on Earth. This is due to the non-linear relationship of Fahrenheit or any temperature scale with its multiples.

The question seems to be asking whether, if the hottest recorded temperature in the world in degrees Fahrenheit is multiplied by 13.46, the result would be equal to ten times that same temperature. This arithmetic operation would not, in reality, be accurate in defining the world's hottest temperature. This is because Fahrenheit temperatures don't have a linear relationship with its multiples. For example, if the highest recorded temperature is 120°F, 10 times that would be 1200 and this temperature is not realistic on earth.

The hottest temperature ever recorded on Earth was 134°F (56.7°C) in Furnace Creek Ranch, Death Valley, California, USA on July 10, 1913. This temperature was recorded using a standard thermometer in a ventilated, shaded structure 1.5 meters above the ground, which is the standard method for measuring ambient temperature. Doubling or multiplying this figure as suggested wouldn't produce a viable result in real-world physics or climatology.
