Answer:

1/5

Step-by-step explanation:

b and c = [tex]\sqrt{50}[/tex]   because 10 x 5 = 50

therefore  the fraction is   √2/ √50

to simplify you need to simplify the √50 into a number of √2 as the top is √2

√50 = √25 x √2

= 5√2

√2/5√2 = 1/5   if you divide both top and bottom by √2

Rayna and Maya are playing the integer card game. The cards in Rayna's hand are shown below: What is the total score of Rayna's hand? Support your answer by showing your work.

Answers

Answer:

The total score of Rayna's hand is described below in details.

Step-by-step explanation:

Start at 0. Combining a positive integer is a simplistic addition. Add 3 to get 3.

Combining a negative integer is like deducting : 3 + (-5) = 3 - 5 = -2.

Add 9, using 9 steps ahead, on the number line, to get 7.

Add -6, by deducting 6, to get 1.

Rayna's total composition is 1.

As for part 2, Rayna obtaining two more cards, which doesn't change his final record ...

Unless he got 2 zeroes, or he got pair cards with different symbols but similar magnitudes, such as 1 and -1.

The sign of a number is whether it is negative or positive. The magnitude (total value) of a number is how far that amount is from zero. The magnitude of a product is never negative.

The 2 cards do not change Rayna's point total, because their influences eliminate each other out. For instance, a 1 would move him one move ahead, on the number line, and a -1 would produce him one move behind, on the number line.

Step-by-step explanation:

Here, we want to multiply the expressions

We take the similar terms together and add the exponent

We have this as:

(8 * -10) * (x^2 * x^3) * (y^0 * y^2) + z

-80z * (x^(2+3)) * (y^(0+2))

Please help! Also please don’t comment just for points it’s not funny and I need this so I can raise my score back up.

Answers

Answer:

x = 8 and x = -3.

Step-by-step explanation:

-x^2 + 5x + 24 = 0   at the x intercepts.

Divide thru by -1:

x^2 - 5x - 24 = 0

(x - 8)(x + 3) = 0

x - 8 = 0 ,  x + 3 = 0

x = 8 and x = -3.

A company is going to make a water tank in the shape of a cylinder. As shown below, the tank will have a height of 4ft and a radius of 6ft. The tank will be made from metal (including its top and bottom). Suppose the total cost of the metal will be $14,318.40. How much will the metal cost per square foot? Use 3.14 for pi, and do not round your answer.

Answers

First find surface area.

I will skip the exact explanation and just go to it because well its the same concept as the prism.

π*6^2*2+6*2π*4

=72π+48π

=120π

Now we need to take 3.14 for pi getting about

120*3.14=376.8 square foot.

Now the total is 14318.4 dollars, so what's left is simple division.

14318.4/376.8=38

The metal cost 38 dollars per square feet :P

Answer: 1.567 × 10⁹

Step-by-step explanation:

1.6 × 10⁹ = 1.6 × 1000000000 = 1,600,000,000

3.3 × 10⁷ = 3.3 × 10000000 = 33,000,000

1,600,000,000 - 33,000,000 = 1,567,000,000

10⁹ = 1,000,000,000

Find and simplify an expression for the area of two rows of b squares with side lengths of b centimeters .

Answers

Answer:

2b³ cm²

Step-by-step explanation:

The Area of each square :

Area of a square = a² ; where a = side length

The side length = b

Hence, Area, A = b² = b² cm²

The total number of squares:

Number of rows * number of squares per row

2 * b = 2b

Therefore, total area :

Total number of squares * area of each square

(2b) * b²

= 2b³ cm²

Now this power, which every man has in the state of nature, and which he parts with to the society in all such cases where the society can secure him, is to use such means for the preserving of his own property as he thinks good and nature allows him, and to punish the breach of the law of nature in others so as, according to the best of his reason, may most conduce to the preservation of himself and the rest of mankind. So that the end and measure of this power, when in every man's hands in the state of nature, being the preservation of all of his society - that is, all mankind in general - it can have no other end of measure when in the hands of the magistrates but to preserve the members of that society in their lives, liberties, and possessions; and so cannot be an absolute, arbitrary power over their lives and fortunes, which are as much as possible to be preserved, but a power to make laws, and annex such penalties to them as may tend to the preservation of the whole, by cutting off those parts, and those only, which are so corrupt that they threaten the sound and healthy, without which no severity is lawful.
