Step-by-step explanation:

Answer:

20

Step-by-step explanation:

Solving  for x using the vertical angles we get , the value of x is: x = 20.

Here, we have,

from the given figure we get,

angle (2 + 3x) and angle62 are opposite angles.

we know that,

When two lines intersect each other, then the opposite angles, formed due to intersection are called vertical angles or vertically opposite angles. A pair of vertically opposite angles are always equal to each other.

so, we have,

angle (2 + 3x) = angle62

(2 + 3x) = 62

or, 3x = 60

or, x = 20

Hence, Solving  for x using the vertical angles we get , the value of x is: x = 20.

Carter;

5 ( x + 9 ) - 3x = 2x + 45

Step-by-step explanation:

Simplify the equation;

5 ( x + 9 ) - 3x

Distribute the 5, remember, you have to distribute 5 over both terms.

5x + 45 - 3x

Combine like terms;

2x + 45

Answer: First Option (5√5)

Answer:

First, you see if there are any perfect squares that are a factor of 125. If you do find some, find what is seemingly the biggest. In this case, it is 25, I think. So you can then out it as root(25×5), I think. As 25 is a perfect square, you can square and then put the number you get on the outside. So since 5×5=25, it becomes 5(root)5, which essentially means 5×(root)5, I think.

Answer:

We can say we start with 490 grams and after 1 year we have (490 * .81 grams) or 396.9 grams.

We can solve for half-life by this equation:

Half life = (time * log 2) / log (beginning amount / ending amount)

Half-life = (1 year * 0.30102999566) / log (490 / 396.9)

Half life = (1 year * 0.30102999566) / log (1.2345679012 )

Half life = (0.30102999566) / 0.091514981109

Half-Life = 3.2894067399  years

Well, that's a start.

Step-by-step explanation:

The half life of the given radioactive isotope will be 3.2894067399  years.

The amount of time it takes to disintegrate by half an initial amount. For a given reaction, a reactant's half-life t-1/2 is the time it takes for its concentration to reach a value which is the arithmetic mean of its initial and final value.

Here, Element X starts with 490 grams

After 1 year we have  (490 X 0.81 grams) or 396.9 grams

Now, We can solve for half-life by this equation:

Half life = (time  X log 2) / log (beginning amount / ending amount)

Half-life = (1 year X 0.30102999566) / log (490 / 396.9)

Half life = (1 year X 0.30102999566) / log (1.2345679012 )

Half life = (0.30102999566) / 0.091514981109

Half-Life = 3.2894067399  years

Thus, the half life of the given radioactive isotope will be 3.2894067399  years.

Answer:

Step-by-step explanation:

P.S Can I have brainliest?

Answer:

6,552

Step-by-step explanation:

Answer:

We know that x is the number of floor tickets they sell, and each one costs $15, then the amount of money they will get by those sells is x times $15, this is:

x*$15.

And y is the number of balcony tickets they sold, each one of these costs $12, then the total amount of money made in those tickets is:

y*$12.

Then the total amount of money that the band made is:

x*$15 + y*$12

And they want to make, at least, $3,000, then we will have the inequality:

x*$15 + y*$12 ≥ $3000

That can´t really be solved, because we have two variables and only one inequality, but this represents the given situation.

Length of scale = 15 cm

Width of scale = 5 cm

Step-by-step explanation:

Dimensions of the kitchen of Mai are given as:

Length of kitchen = 6 m

Width of kitchen = 2 m

Scale to be used = 1 to 40

To find:

The drawing with labeling and dimensions of the scale drawing.

Solution:

First of all, let us understand about the concept of scaling.

Scaling is a method to represent big structures on paper.

For this purpose, we decide a scaling factor and draw the big structures on paper by scaling down (making it small) by using a scaling factor.

Here, the scale factor used is 1 to 40.

i.e. 1 unit on scale is equivalent to 40 units on the actual kitchen.

40 units of kitchen = 1 unit of scale

1 unit of kitchen = [tex]\frac{1}{40}[/tex] units of scale

6 m of kitchen = [tex]\frac{1}{40}\times 6\ m = \frac{600}{40}\ cm = 15\ cm[/tex]

Length of scale = 15 cm

40 units of kitchen = 1 unit of scale

1 unit of kitchen = [tex]\frac{1}{40}[/tex] units of scale

2 m of kitchen = [tex]\frac{1}{40}\times 2\ m = \frac{200}{40}\ cm = 5\ cm[/tex]

Width of scale = 5 cm

Please refer to the attached image as well for representation of given scale.

Dave's rate of completion is 4/3 walls per hour and this can be determined by using the concept of unit rate.

Given :

The following steps can be used in order to determine Dave's rate of completion:

Step 1 - The concept of unit rate can be used in order to determine Dave's rate of completion.

Step 2 - According to the given data, Dave completes on average 2/3 of a wall in 1/2 of an hour.

Step 3 - Now, let Dave's rate of completion be 'x'.

Step 4 - So, the value of 'x' can be calculated as:

[tex]x = \dfrac{\dfrac{2}{3}}{\dfrac{1}{2}}[/tex]

Step 5 - Simplify the above expression.

[tex]x = \dfrac{2}{3}\times\dfrac{2}{1}[/tex]

[tex]\rm x = \dfrac{4}{3}\;walls \;per \;hour[/tex]

Therefore, Dave's rate of completion is 4/3 walls per hour.

Answer:

8

Step-by-step explanation:

15 - .75g = 13 - .50g

2 = .25g

8 = g

If Deanna starts with $15, and the machine she is playing costs $0.75 per game. Lulu starts with $13, and her machine costs $0.50 per game.Then after 8 games will the two friends have the same amount of money remaining

Two or more expressions with an Equal sign is called as Equation.

Given,

Let g represents game

Deanna starts with $15, and the machine she is playing costs $0.75 per game

So the equation will be

15 -0.75g

Lulu starts with $13, and her machine costs $0.50 per game.

The equation for Lulu will be

13 - 0.50g

Now let us equations of both Deanna and Lulu

15 -0.75g =13 - 0.50g

15-13=0.75g-0.50g

2 = 0.25g

Divide both sides by 0.25

8 = g

Hence after 8 games  the two friends have the same amount of money remaining
