Answer:

0.9

Step-by-step explanation:

We can tell straight away which is greater.

Like I said, fractions are like money

:$

9/10 is 0.9

Which means

0.9 IS a positive number

Remember

THE P-BODY RULE

A POSITIVE NUMBER, NO MATTER HOW LOW IT IS

will always ALWAYS

be greater than a negative number.

Answer: 4

Step-by-step explanation: it is 4 because there are a total of 4 different decimal places in the equation so if the equation was 1.2 times 1.2 you would decimal hop 2 times because there are to numbers behind the decimal

Answer:

1999 × 24 = 47976

In 1.999 the are 3 digits after the decimal. In 2.4 there is 1 digit after the decimal.

3 + 1 = 4

We move the decimal 4 places to the left or 1 place to the right of 47976.

Answer:

statement are always true

Sometimes True:

The sum of a rational number and an irrational number is rational.

Always True:

The product of two rational numbers is always rational.

Always True:

The sum of an irrational number and a rational number is irrational.

Sometimes True:

The product of an irrational number and a rational number is irrational.

Always True:

The sum of two rational numbers is rational.

A rational number is a number that can be written in the form of p/q where q is not equal to zero.

We have,

Sometimes True:

The sum of a rational number and an irrational number can be rational or irrational depending on the numbers chosen.

For example, 1 + √2 is irrational, but 1/2 + √2/2 is rational.

Always True:

The product of two rational numbers is always rational, as can be shown using the definition of rational numbers.

Always True:

The sum of an irrational number and a rational number is always irrational. This can be shown by contradiction.

Assume that the sum of an irrational number a and a rational number b is rational.

Then (a + b) - b is also rational, which implies that a = (a + b) - b is rational, contradicting the assumption that a is irrational.

Sometimes True:

The product of an irrational number and a rational number can be rational or irrational depending on the numbers chosen.

For example, √2 x 2 is irrational, but √2 x (1/√2) = 1 is rational.

Always True:

The sum of two rational numbers is always rational, as can be shown using the definition of rational numbers.

Thus,

Sometimes True:

The sum of a rational number and an irrational number is rational.

Always True:

The product of two rational numbers is always rational.

The sum of an irrational number and a rational number is irrational.

Answer:

Step-by-step explanation:

number of side = n =7

Sum of all the angles of  given polygon = (n -2)*180 = 5 *180 = 900

x + 140 +133 +145 + 117 + 119 + 125 = 900

math is so hard but I'm learning

Answer: To determine if two lines are parallel or perpendicular, you have to look at the slopes. For the line y=kx+b, k is the slope.

For two lines  y=k1x+b1 and y=k2X+b2 ,When K1=K2, two lines are parallel; when K1=-1/k2, two lines are perpendicular. It doesn't matter whatever b1, b2 are. Hence to save time, you only need to calculate  k1 and k2.

To calculate the slope k of any line, you have to change the equation to y=kx+b

For -y=3x-2, k=3/(-1)=-3 (you divide -1 on each side of =, but you don't need to calculate -2/(-1))

For -6X+2y=6, K=6/2=3 (you first move the -6x to right side, it becomes 6x, then divide by 2)

Now you can get the answer: The two lines neither parallel nor perpendicular.

Step-by-step explanation:

The measurement is closest to the distance in miles the airplane will fly along the diagonal is given by D = 476.1 miles

The diagonal of a rectangle is calculated by the formula

From the Pythagoras Theorem , The hypotenuse² = base² + height² , and

Diagonal of a Rectangle = √ ( Length )² + ( Width )²

Given data ,

Let the dimensions are represented by the rectangle be 280 mi x 385 mi

So , the length of the rectangular path L = 280 miles

The width of the rectangular path W = 385 miles

And , the distance in miles of airplane along the diagonal is given by

Diagonal of a Rectangle = √ ( Length )² + ( Width )²

On simplifying , we get

The distance along the diagonal D = √ ( 280 )² + ( 385 )²

The distance along the diagonal D = √ ( 78400 + 148225 )

The distance along the diagonal D = √ ( 226625 )

The distance along the diagonal D = 476.1 miles

Hence , the distance is D = 476.1 miles

Based on the measurements shown in the map, which measurement is closest to the distance in miles the airplane will fly along the diagonal?

A 665.0 mi

B 25.8 mi

C 36.4 mi

D 476.1 mi

Answer:

Step-by-step explanation:

y = mx + b

m is the slope (what you want)

b is the y-intercept, which is the value of y when x = 0

Oh, right, we already have b, isn't that great!

Given point (0, -4), so b = -4

Point (-2, -1), where x = -2 and y = -1

-1 = -2m -4 (solve for m)

3 = -2m

m = -3/2

Check:

y = -3x/2 -4

y = -3(-2)/2 -4  -> should get y = -1

y = 3 -4 = -1

Yay, we have the answer!
