Answer:

-17.25

Step-by-step explanation:

So first you add -8.3 and -7.7, from there you get -16.

-1 1/4 would be -1.25 as a decimal. So all you do is add -16 and -1.25 and you get -17.25 as your answer

The average temperature, in degrees Fahrenheit, at the North Pole in January is -17.25

We have got an equation that can relate these three units of measurement of temperature, as given below:

[tex]\dfrac{C}{5} = \dfrac{F - 32}{9} = \dfrac{K - 273}{5}[/tex]

where C represents the measurement of a fixed temperature in celsius, F represents the measurement of that same intensity temperature in fahrenheit, and K represents the measurement of equally intense temperature in kelvin.

We are given that the average temperature at the North Pole is -8.3 degrees Fahrenheit.

In December, the average temperature at the North Pole = 7.7 degrees Fahrenheit colder than November's average temperature.

In January, the average temperature at the North Pole = 1 1/4 times colder than December's average temperature.

So first we need to add -8.3 and -7.7

-8.3 + -7.7=  -16.

-1 1/4 = -1.25

Now,  add -16 and -1.25

-16 +  -1.25 =  -17.25

Step-by-step explanation:

Answer:

$625

Step-by-step explanation:

to find the original divide the sale price by the decreased percentage. 125/%20(or .20)

===========================================================

Work Shown:

1 ft = 12 inches

1 ft, 2 inches = 12 inches + 2 inches .... add 2 inches to both sides

1 ft 2 inches = 14 inches

Now we'll use the scale ratio to help find the answer

(2 inches)/(5 miles) = (14 inches)/(x miles)

2/5 = 14/x

2x = 5*14

2x = 70

x = 70/2

x = 35

The distance between the two locations is 35 miles.

Answer:

7x² + x + 14

Step-by-step explanation:

(2x² + 6x + 4) + (5x² - 5x + 10)

Remove parentheses

2x² + 6x + 4 + 5x² - 5x + 10

Put like terms together.

2x² + 5x² + 6x - 5x + 4 + 10

Simplify.

7x² + x + 14

Answer: (286/11) ÷ 2 = 13

Step-by-step explanation:

The quotient of 286 and 11 is given by the equation A = 26

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the first number be represented as x

Now , the value of x = 286

Let the second number be represented as y

The value of y = 11

Let the quotient be represented as A

The value of A is given by the equation ,

A = x/y

Substituting the values in the equation , we get

A = 286/11

The value of A = 26

Therefore , the value of A is 26

Hence , the equation is A = 26

Answer:

360 square meters.

Step-by-step explanation:

You can split the polygon into three rectangles. Then you just have to figure out the area of each rectangle and add them together. The first rectangle has length of 12 and height of 10 so area of 120. The second rectangle has length of 32 and height of 6 so area of 192. The third rectangle has length of 8 and height of 6 so are of 48. 120 + 192 + 48 = 360

Answer:

x = 16

m<R = 34°

Step-by-step explanation:

▪︎Its an isoceles triangle, so the two opposite angles are equal. m<S = <T.

▪︎So, you write them equal to each other and solve the linear equation to find x.

▪︎Substitute the x value into any of the angles and multiply by 2, (as they are equal) to find the sum, which is 146°.

▪︎Sum of all angles in a triangle is 180°,so

146° + m< R =180°

▪︎than minus 146° from 180°.

▪︎And you will have your answer.

Answer:

  Vertex: (-1, 4)

  Maximum: f(-1) = 4

  Increasing: (-∞, -1)

  Decreasing: (-1, ∞)

Step-by-step explanation:

The equation can be written in vertex form by "completing the square."

First factor out the leading coefficient from the x-terms.

  f(x) = -(x² +2x) +3

Then add the square of half the x-coefficient inside parentheses. Add the opposite of that amount outside parentheses.

  f(x) = -(x² +2x +1) +3 +1

Write in vertex form.

  f(x) = -(x +1)² +4 . . . . . . . compare to a(x -h)² +k

You can see that the vertex is (h, k) = (-1, 4), and that the vertical scale factor 'a' is negative. This means the vertex is the maximum and the parabola opens downward.

The function will be increasing to the left of the maximum, decreasing to its right.
