During a sale, the price of a lounge suite dropped from $1600 to $1250. What was the percentage decrease in price?

Answer:

69.9 (nice)

Step-by-step explanation:

To solve this, use the order of operations: PEMDAS (Parenthasis, exponents, Multiplication/Division, Addition/subtraction) In order.

1. Solve in the parenthasis, (2+3³).  3³ = 27, so 2+27 is 29. Plug in 29 to the equation: 5³-29×1.9

2. Next is exponents. 5³ has an exponent, which equals 125. Now you plug that into the equation to be 125-29×1.9

3. Now comes multiplication/division. In this case, it's multiplication. -29×1.9 . This equals -55.1, and you once again plug  this into the equation to simplify which gives you 125 - 55.1

4. Last in the order of PEMDAS is addition/subtraction. The final simplification of the equation is 125 - 55.1 which is subtraction and this equals 69.9 (nice)

So in conclusion, your answer is 69.9 (nice)

Answer:

 10 square units

Step-by-step explanation:

The given equation is in "intercept form." This lets you see immediately the x-intercept is 4, and the y-intercept is 5. This makes the area be that of a right triangle with base 4 and height 5:

  A = 1/2bh = 1/2(4)(5) = 10 . . . . square units

We have a sequence that meets the given criteria, and with that information, we want to get the sum of all the terms in the sequence.

We will see that the sum tends to infinity.

So we have 5 terms;

A, B, C, D, E.

We know that the sum of each term and its neighboring terms is 15 or 25.

then:

Now, we want to find the sum of all the terms in the sequence (not only the 5 given).

Then let's assume we write the sum of infinite terms as:

[tex]a_1 + a_2 + a_3 + a_4 + a_5 + a_6 + ...[/tex]

Now we group that sum in pairs of 3 consecutive terms, so we get:

[tex](a_1 + a_2 + a_3) + (a_4 + a_5 + a_6) + ...[/tex]

So we will have a sum of infinite of these, and each one of these is equal to 15 or 25 (both positive numbers). So when we sum that infinite times (even if we always have the smaller number, 15) the sum will tend to be infinite.

Then we have:

[tex](a_1 + a_2 + a_3) + (a_4 + a_5 + a_6) + ... \to \infty[/tex]

Answer:

m∠O = 80°

Step-by-step explanation:

m∠O = 4x - 20

m∠Q = 3x + 5

m∠O and m∠Q are congruent

4x - 20 = 3x + 5

Solve for x = 25

Plug back in

m∠O = 4(25) - 20

m∠O = 100 - 20

m∠O = 80°

Answer:

2/3

Step-by-step explanation:

1. The easiest way to find the slope of the line is by converting this equation into slope-intercept form (y = mx + b).

2. (Solving)

Step 1: Simplify both sides of the equation.

Step 2: Add 3 to both sides.

Step 3: Divide both sides by 3.

3. Since 2/3 is in place of m, the slope, the slope of the line is 2/3.

Answer:

Step-by-step explanation:

when the value is below 2

a situation in which no identifiable relationship exists between the values of the error term.

The value of Durbin–Watsons statistic indicates no autocorrelation is present is 2.

The output of a regression model is tested for autocorrelation using the Durbin-Watson statistic. Zero autocorrelation is indicated by a value of 2.0 in the DW statistic, which has a range of zero to four. Positive autocorrelation is indicated by values below 2.0, and negative autocorrelation is shown by values over 2.0.

As, The range of the Durbin-Watson statistic is 0–4. There is no first-order autocorrelation when the number is 2 or close to 2.

The range of 1.50 to 2.50 is suitable.

A number between 0 and 4 will always be assigned to the Durbin-Watson statistic.

A value of 2.0 means that no autocorrelation in the sample was found. Positive autocorrelation is shown by values between 0 and less than 2 whereas negative autocorrelation is indicated by values between 2 and 4.

Answer:

1)y=2x+7

2) unsure what the question is due to blur

3)y=3/4x-2

4)y=-2x

Answer:

Step-by-step explanation:

1) (1,9) ; slope = 2

Point slope form:

y - y₁ = m(x - x₁)

y - 9 = 2(x - 1)

Slope intercept form:

y - 9 = 2x - 2

    y = 2x - 2 + 9

 y = 2x + 7

3) (-4 , -5)  ; slope = 3/5

Point slope form:

y - y₁ = m(x - x₁)

[tex]y - [-5] = \dfrac{3}{4}(x - [-4])\\\\\\y + 5 = \dfrac{3}{4}(x + 4)[/tex]

Slope intercept form:

[tex]y + 5 = \dfrac{3}{4}x + 4*\dfrac{3}{4}\\\\y + 5 =\dfrac{3}{4}x + 3\\\\y = \dfrac{3}{4}x +3 -5 \\\\\\y = \dfrac{3}{4}x - 2[/tex]

Answer:

The second table with all values of x = -5 does not represent a function. what the function and input value of x will return one and only one value for y. and this table when you input a value for x of -5 you get three different values therefore this table does not represent a function

Answer:

Step-by-step explanation:

The table

x y

-5 1

-5 -2

-5 -5

does not represent a function, because for the same input (-5) there are 3 different outputs.

Compare this to the table

 x y

-5 1

-3 -2

-1 -5

in which all the inputs (x values) are unique (one of a kind) and each input has exactly one output (y value) connected to it.

Part A: Total amount of juice left = 0.25 + 0.30 + 0.75 - 0.20

Answer:

1.5

Step-by-step explanation:

to find one hour you divide both answers by 1.5 giving you one hour and 1.5

1.5 yards did you mow in 1 hour when, You mowed 2.25 yards in 1.5 hours.

Division is the process of splitting a number or an amount into equal parts.

Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication.

here, we have,

You mowed 2.25 yards in 1.5 hours.

in 1 hours I mowed = 2.25/1.5

                               =1.5

Hence, 1.5 yards did you mow in 1 hour.

Answer:

A

Step-by-step explanation:

The Explication 0 (7+4i)+(7-4i) = 14

The correct equation which demonstrates the additive identity property is,

⇒ (7 + 4i) + 0 = 7 + 4i

The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.

Now, If we add a real number to zero or add zero to a real number, then we get the same real number back.

Hence, The number zero is known as the identity element, or the additive identity.

For example: a + 0 = a

Hence, we can see that;

⇒ (7 + 4i) + 0 = 7 + 4i

Since, 0 is the additive identity here.

Thus, The correct equation which demonstrates the additive identity property is,

⇒ (7 + 4i) + 0 = 7 + 4i
