Answer:

640

Step-by-step explanation:

In order of operations, do exponents before multiplying.

8 squared= 64

64 x 10=640

Answer:

Step-by-step explanation:

There are two sides on a coin, heads and tails. So, the probability  of flipping heads is going to be 1/2, as there is one chance out of the two options that you will flip a head. As for spinning blue, there are 3 options that are blue out of the four color options given. So, the probability of spinning blue would be 3/4. Hope this helped :) Take this with a grain of salt, though. It's been a while since I reviewed probabilities.

The required probability of landing on heads and spinning blue is 3/4.

Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

There are two sides to a coin, heads, and tails.

So, the probability of flipping heads is going to be half, as there is one option out of the two options that you will flip a head.

As for spinning blue, there are three choices that are blue out of the four color options given.

So, the required probability = favorable outcomes / total outcomes

So, the required probability = 3/4

Hence, the probability of spinning blue would be 3/4.

Answer:

8x + 4

Step-by-step explanation:

Simplified

group like terms: (+5x + 1X + 2x) = 8x (-4 + 8) = 4 add the positive sign so you can get an equation: +4, so your simplified expression would be 8x + 4

Answer:

825 g

Step-by-step explanation:

Here's my work:

500g Cl2 l   1mol Cl2  l  2 mol NaCl   l  58.5 g NaCl

                l   71 g Cl2    l  1 mol Cl2      l    1 mol NaCl  

= 823.94  - the rounding can be a little off

The first thing you have to do is convert the 500 g of Cl2 into moles.  So you get the mass of Cl which is 35.5, but Cl is diatomic by itself so you multiply 35.5 x 2 and get 71.   now on the third column you are comparing the mol ratios of the equation.  The equation is 2Na + Cl2 ---> 2NaCl, so you see that there is no coefficient in front of Cl2 so that means there is 1 mol, and then you see that in the product there is a  coefficient of 2 in front of NaCl so that means there is 2 moles.  Then finally you have to convert the moles backs into grams where you just add the masses of Na and Cl .  You multiply across the top  and then divide that number by the bottom row.

Answer:

11.8

Step-by-step explanation:

18% of 10 so more the decimal only one time because you only have one 0 and you get 1.8. ok then 1.8 to 10 =11.8

The book cost $11.8  when the book store increases its prices by 18%.

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, A book cost $10 at one book store which is 100% of its price.

Now, The book store increases its prices by 18%.

Therefore, The new price of the book is (100 + 18) = 118% of $10 which is,

= (118/100)×10.

= 1.18×10.

= $11.8

Answer:

$9100

Step-by-step explanation:

Cost price = 100/(100-loss%)* Selling price

CP = 100(100-93)*637

Answer:

Infinite solutions

Step-by-step explanation:

1) First, you can solve this easily by elimination. Multiply the first equation by -2 in order to cancel out terms when adding to the second equation.

2) Then, add the new set of equations together. However, everything cancels out, bringing us to 0 = 0. This means that the lines the equations make must be the same. Thus, all real numbers must make this equation true, meaning that there are infinite solutions.

Step-by-step explanation:

3x + 2y = 4

2y = -3x +4

y = -3/2x +2

6x+4y = 8

4y = -6x +8

y = -6/4x + 8

y = -3/2x + 8

same slope, bit different intercepts. they are parallel. no solutions

Answer:

Probability that the product is an odd number =  [tex]\frac{1}{7}[/tex]

Step-by-step explanation:

Given - Patryk has 7 cards.  There is a number on each card.  2 3 4 5 6 7 8

            Patryk takes two of the cards at random.  He works out the product  

            of the numbers on the two cards.

To find - Work out the probability that the product is an odd number.

Proof -

As we know that Product of two numbers is odd iff both the numbers are odd.

So, we have to find the probabilty that both the card that Patryk choose is odd

Now,

Total number of cards = 7

Total number of odd cards = 3

So, Probability = ³C₂ / ⁷C₂

                       = [tex]\frac{3!}{2! (3-2)!}. \frac{2! (7 - 2)!}{7!}[/tex]

                      = [tex]\frac{3!}{2! (1)!}. \frac{2! (5)!}{7!}[/tex]

                      = [tex]\frac{3!}{(1)!}. \frac{ (5)!}{7.6.5.4.3!}[/tex]

                      = [tex]\frac{ 5.4.3.2.1}{7.6.5.4}[/tex]

                      = [tex]\frac{1}{7}[/tex]

∴ we get

Probability that the product is an odd number =  [tex]\frac{1}{7}[/tex]

Unit rate is 8 / 15 acres per day.

"Work is defined as when force is applied on an object and it gets move in particular direction."

According to the question,

Group of workers plant  2/ 5 acres  in 3 /4 days

3 / 4 days = 2/ 5 acres

1 day =  [tex]\frac{2}{5}[/tex] × [tex]\frac{4}{3}[/tex]
