Answer:

80

Step-by-step explanation:

Dale spends 12 hours on the internet, 75% on messages and 25% on games.

To make this easier, we can just convert the percentages into fractions and then continue.

To turn a percentage into a fraction, take the percentage number and put it into the numeriator, and add 100 to the denominator.

75% = 75/100  

25% = 25/100

Simplify!

75% = 75/100 = 3/4

25% = 25/100 = 1/4

So, now we know how to convert the percentages into a fraction. Now! We must use the fractions to find out how to find the time he uses to play games.

We know now that he spends 1/4 of his time working on games, and 3/4 of his 12 hours working on messages. However, we want to know how much 1/4 is. Divide 12 by the denominator, 4, and this will determine how long 1/4 is.

12 / 4 = 3  

So, that means that of his 12 hours he spends on the internet, he spends 3 hours doing games.

Now, subtract the time he spends doing the games by the time he spends on the internet to find the time on he spends messaging.

12 - 3 = 9

Which means that:

9 = Hours Spent Doing Messaging

3 = Hours Spent Playing Games

Step-by-step explanation:

If L || M. Then the value of the variable 'x' will be 17.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

It is a polygon with four sides. The total interior angle is 360 degrees. A rectangle's opposite sides are parallel and equal, and each angle is 90 degrees.

The side of the rectangle is L and M. If L || M.

L = 8x + 20

M = 11x - 31

Then the value of 'x' is given as,

M = L

11x - 31 = 8x + 20

11x - 8x = 20 + 31

3x = 51

x = 17

If L || M. Then the value of the variable 'x' will be 17.

Answer:

52/[(8 - 2) + (10 - 3)]

Step-by-step explanation:

Jeff earns $8 and spends $2 each week.

Each week he keeps (8 - 2).

Joe earns $10 and spends $ each week.

Each week he keeps (10 - 3).

The total amount they keep each week is

(8 - 2) + (10 - 3).

If you divide the cost of the game by the amount they keep each week, you get the number of weeks.

Answer: 52/[(8 - 2) + (10 - 3)]

Answer:

24.5h + 34

Step-by-step explanation:

8.5(4 + 3h) - h

= 34 + 25.5h - h

= 24.5h + 34

I hope this helped!

The simplified form of 8.5(4+3h)-h is 24.5 + 34.

A numerical expression is in the form of variables and constants separated by the operation of addition and subtraction. We can also form numerical expressions from statements.

Given an expression in variable h which is 8.5(4+3h)-h.

First, we'll apply distributive law to get rid of the bracket and separate the different terms. There are two more laws they are associative law and commutative law.

Distributive law state that a(b+c) = ab + bc.

34 + 25.5h - h.

24.5h + 34.

Answer:

x = 2

Step-by-step explanation:

Is it -1/2 or just 1/2 I'll just answer both

x = 4

So -1/2 of x or -1/2 of 4 is -2

And 1/2 of 4 is 2.

So the answer is most likely 2

and is probably point z

4/(-1/2) = -2

Answer: 46-3i

Step-by-step explanation: Use the FOIL method, (a+b)(c+d)=ac+ad+bc+bd. Collect like terms then simplify.

(6+7i)(3−4i)

18−24i+21i+28

(18+28)+(−24i+21i)

46-3i

- Hope this helps, have a blessed and wonderful day! :-)

In the standard form we can write (6 + 7i)(3 − 4i) as (- 3i + 46).

A complex number is a number of the form a + bi, where [a] and [b] are real numbers and [i] is equal to [tex]\sqrt{-1}[/tex].

Given is the following complex expression -

(6+7i)(3−4i)

We have -

(6 + 7i)(3 − 4i)

On expanding, we get -

6(3 - 4i) + 7i(3 - 4i)

18 - 24i + 21i - 28i²

18 - 3i - 28i²

18 - 3i - 28 (-1)

18 - 3i + 28

46 - 3i

- 3i + 46

Therefore, in the standard form we can write (6 + 7i)(3 − 4i) as (- 3i + 46)

The answer is you have to remove 4 points.

There is 6 points in all and for a function it only needs two points to become a function. A function needs to be a that line that passes the vertical line test. For example: A circle is not a function because when you perform the vertical line test you'll see that many points share a common x-value and a function needs only one output in every input.

Step-by-step explanation:

Correction:

A trader sells 5 mobiles for Rs 35840 and had profit of 12% . Find the cost price of each mobile.

Solution:

Selling price of 5 mobiles = Rs 35840

Now, we have to find the selling price of 1 mobile. So, for the cost of 1 mobile , the cost of 5 mobiles is divided by 5.

i.e [tex]\frac{35840}{5} =[/tex] Rs [tex]7168[/tex]

We have,

Cost of 1 mobile = Rs 7168

Profit % = 12 %

Finding the cost price of each mobile :

[tex]\boxed{\sf{ CP = \frac{SP * 100}{100 + Profit percent}}}[/tex]

[tex]CP = \frac{7168 * 100}{100 + 12}[/tex]
