Answer:

14 hours, -22 hours

Step-by-step explanation:

10:00 AM to 12:00 PM = 2 hours

12:00 PM to 12:00 AM = 12 hours

12 hours + 2 hours = 14 hours

14 hours - 36 hours = -22 hours

Answer:

there should not be negative number in rational number

Let  x be the first integer , y be the second integer , and z be the third integer

x < y < z < 25

We know that

Median=13

Median=(x+y+z)/3

13=(x+y+z)/3

x+y+z=39------> equation 1

Range=10

The range is the difference between the largest number within the set and the smallest number in the set

So  range=z-x

z-x=10------> z=x+10-----> equation 2

to find the solution we will assume different values ​​of x (See the attached table)    

terms

x < y < z < 25

z=x+10

y=39-z-x

The solution can be

7,15,17

8,13,18

9,11,19

Answer:

The Sahara Desert is 258 °F warmer that Antarctica.

Step-by-step explanation:

Temperature at Antarctica = -123 °F

Temperature at the Sahara desert = 135 °F

The difference in temperature = 135 - (-123) = 135 + 123 = 258 °F

This means that the Sahara Desert is 258 °F warmer that Antarctica.

Answer:

315 degrees

Step-by-step explanation:

360 degrees make a full circle, and since you've already turned 45 degrees, you will need 315 degrees more.

Answer:

Hey!

To turn it all the way to its starting position is the same as turning it 360 DEGREES...so your answer will be 315 DEGREES MORE!

Step-by-step explanation:

PROOF : 315 + 45 = 360 OR 360 - 45 = 315

Answer:

Its C

Step-by-step explanation:

The sign of the resultant value will depend upon added values and the sum will have the sign of the addend with the lesser absolute value so the correct option will be (C).

A summation, also abbreviated as a sum, is the outcome of adding two or more numbers or quantities. Here are always an integer number of terms in a summation. There could be only two terms, but there could be one hundred, thousand, or a million. There are summations with an infinite set of parameters.

In other words, the summation is the addition or subtraction of any two or more terms. As a result, we have a new result that may be large or little, depending on the quantity.

In given question

Let's suppose we add +5 + (-7) = -2 so here the sign is negative because the 5 is greater than the -7 so it is clear by this example that the sign of the addend with the lesser absolute value.

Answer:

160

Step-by-step explanation:

We are given the equation:

k^5 * m

and asked to evaluate for k=2 and m=5. Therefore, we must substitute 2 for k and 5 for m.

(2)^5 * 5

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition and Subtraction.

Evaluate the exponent first.

—> (2)^5 = 2*2*2*2*2= 32

32 *5

Multiply 32 and 5.

160

The expression: k^5 * m when evaluate for k=2 and m=5 is equal to 160.

Answer:

y=4x-8 hope this helps:)

Step-by-step explanation:

Hey there!!

You can find the equation of a st.line passing through points using one point formula if only one point is given and slope is given , else find it by using two point formula (if 2 points are given).

Here, the points are, (4,8) and (-1,-12).

Using two point formula,

[tex](y - y1) = \frac{y2 - y1}{x2 - x1} (x - x1)[/tex]

Keep all values,

[tex](y - 8) = \frac{ - 12 - 8}{ - 1 - 4} (x - 4)[/tex]

Now, simplify them.

[tex](y - 8) = 5(x - 4)[/tex]

y - 8 = 5x -20

5x -y -20+8 = 0

Therefore, 5x - y -12 = 0 is the required equation.

Answer:

16.5 Squared Inches

Step-by-step explanation:

A 8.5''x11'' paper would be 7.5 in by 10 in with 1 inch margins. 7.5 x 10=75 in^2.

A landscape paper is 11''x8.5'' which would be 9 in by 6.5 in with 2 inch margins. 9 x 6.5=58.5 in^2.

75 inches squared-58.5 inches squared is 16.5 inches squared.

Therefore, you would lose 16.5 squared inches of writing space.

Answer:

There are 5 pages.

5

You read p pages.

5 - p,

or

(5 - p) ≤ 0

The answer to this expression will equal the amount you read.

The number of pages left to read will be = 5 - P.

We have a five page article.

We have to determine number of pages of this article left to read if you read P pages in the form of expression.

Assume the number of questions left be n. Then -

n = x - y

According to the question, we have -

The number of pages in the article = 5

The number of pages completed = P

Hence, the number of pages left to read will be = 5 - P.

Step-by-step explanation:

Two lines that are perpendicular to each other has -1 as the product of thir gradient.

Since the gradient of the line y = 3 - x is -1, the gradient of the other line must be 1.

So y = x + c.

When x = 7, y = 1. 1 = 7 + c, c = -6.

Hence the equation of the line is y = x - 6.

Answer:

  A = (1/2)Cr

Step-by-step explanation:

You're supposed to observe that the circle area decomposes into what is approximately* a parallelogram with height equal to the circle radius and base equal to half the circumference. The area is then ...

  A = bh

  A = (1/2)Cr

If you fill in the formula for C, you find this matches the formula for the area of a circle:

  A = (1/2)(2πr)(r) = πr²

_____

* In the limit, as the number of sectors approaches infinity, this is exactly a parallelogram.

Step-by-step explanation:

[tex]4+y=9.5[/tex]

Let's simplify this equation.

To solve this equation, we must first subtract 4 from both sides of the equation.

[tex]y+4-4=9.5-4[/tex]

Let's see what we got.

[tex]y=5.5[/tex]

Now you got your answer!

Hope this helps!

The value of y is 5.5 .

Given,

4 + y = 9.5

Equation : 4 + y = 9.5

Let's simplify this equation

To solve this equation, we must first subtract 4 from both sides of the equation.

Resultant equation :

4 - 4 + y = 9.5 - 4

0 +y = 5.5

Thus the value of variable y = 5.5 .

[tex]4 \frac{14}{99}[/tex]

Step-by-step explanation:

First off - chill with the caps dude.

Let's convert this to a mixed number.

We know that any one digit number divided by 9 will get us a repeating decimal of the number we divided by 9. For example, [tex]5 \div 9[/tex] will be [tex]0.\overline{55}[/tex].

The same goes for two digit numbers when they are over 99. [tex]32\div 99 = 0.\overline{32}[/tex]

So this means that to make [tex]0.\overline{14}[/tex] a fraction, we put 14 over 99.

[tex]\frac{14}{99}[/tex]

4 as a fraction is just [tex]\frac{4}{1}[/tex] but since they want it in a mixed number, we can just put a 4 in the beginning of the fraction.

So we get  [tex]4 \frac{14}{99}[/tex].

Answer:

x + 6 and x - 2

Step-by-step explanation:

Given

x² + 4x - 12

Consider the factors of the constant term (- 12) which sum to give the coefficient of the x- term (+ 4)

The factors are + 6 and - 2, since

6 × - 2 = - 12 and 6 - 2 = + 4 , thus

x² + 4x - 12 = (x + 6)(x - 2) ← in factored form

Answer: T=4

Step-by-step explanation:

Answer:

T=4

Step-by-step explanation:

When you plug in x, or 6, you get that x-6= -2.

Keeping that in mind, you then have to think what minus 6 equals negative 2, and 4-6= 4
