You have 6 boys to every 5 girls in math class. How many boys are in class if there are 30 girls in the class.

Answer:

Step-by-step explanation:

Apparently, your system of equations is supposed to be ...

We can multiply the first equation by 2 and subtract the second equation:

  2(4b -3h) -(5b -6h) = 2(64) -(44)

  3b = 84

  b = 28

Using the first equation, we can find the price of a hand towel:

  4b -64 = 3h

  h = (4/3)(b -16) . . . . . divide by 3 and factor out 4

  h = (4/3)(28 -16) = 16

Bath towels cost $28 each, and hand towels cost $16 each.

1. The average change in population is not the same now as it was 50 years ago. The population growth rate can vary greatly from year to year and decade to decade, and is influenced by a variety of factors such as birth and death rates, immigration, and emigration. Therefore, it is important to analyze the specific data for each time period to determine the average change in population.

2. When interpreting data on population growth or decline, it is important to consider the factors that influence population change and to analyze the data in the context of the specific time period being studied. It is also important to consider the accuracy and reliability of the data source, as well as any potential biases or limitations in the data.

3. When comparing population growth or decline over different intervals of time, it is important to consider a range of factors that can influence population change, such as birth and death rates, migration patterns, economic and environmental conditions, and government policies. For example, population growth rates in a country may be influenced by changes in healthcare access or advancements in technology that reduce infant mortality rates or increase life expectancy. In addition, migration patterns can greatly impact population growth rates, as some regions may experience large influxes of immigrants or emigrants at different periods in time. When comparing population data over different intervals of time, it is important to take into account these and other factors that may contribute to population growth or decline.

Answer: Well if you were going to think of a circle you can divide it into 4 equal sizes in one of the is equal to two pentagons and a half. If you add all is equal to a loop full of pentagons [which makes 10 pentagons]. Because the ring is made out of regular pentagons, we can work out that each of the interior angles of each pentagon is 108* degrees. By extending the lines that two pentagons share, assuming they will all meet in the middle, it will create a triangle. As we know each angle of a [regular] pentagon is 108* degrees, we know the two base angles of the triangle would equal to 72** which leaves the top angle to be 36 degrees. As [the sum of] angles at a point is 360 degrees, and 36 is divisible by 360, it will make a complete ring. Also, as 360 ÷ 36 = 10, we know that the ring will be made out of 10 pentagons. as formula to calculate the the size of a interior angle of a polygon is (n×180−360)÷n (for n being the number of sides that the polygon has). because the triangle is made by extending the lines, and angles on a line is 180 degrees, 180−108 (an interior angle of a pentagon) =72.

Answer: 6 divided by 3/4 is 8

Step-by-step explanation:

First when you divide 6 and 3/4. We use a dividing a fraction by a whole number. We have to make 3/4 into 4/3 to make it easier because we are trying to have a whole number. Then you multiply 6 and 4 to get 24 then you divide by 3 so you get 24/3. When you divide this, you get 8.

Once up a time there were 6 and there were 3/4. 6 was the big guy. 3/4 was the smallest in the hood. they were enemies. One day they had a fight and 6 was divided by 3/4 and became 0.5 or 1/2. now 3/4 was the big guy.

Step-by-step explanation:

(2x + 45)° and x° are supplmentary angles.

(Sum of angles on a straight line = 180°)

Hence 2x + 45 + x = 180, 3x = 135, x = 45.

Answer:

what is the question ?

Step-by-step explanation:

Answer:

The formula is basically the same. For the square, we have to multiply

L x W (length x width)  : SQUARE

And for the cube, it is kind of the same but there is the height also in it.

LxWxH (Length x width x height)  : CUBE

Both of these shapes formula is basically the same, but because the cube is 3D, that's why there is height also in it, so it multiplies the height also to find the volume. While for the square, it's 2d, so there's just Length and Width to multiply with.

CONCLUSION:

The formula to find the square's and cube's volume is basically the same, except that for the cube, we have to multiply the height ALSO.

The image vertices of L′M′N′ if the preimage is rotated 90° clockwise are,

⇒ L′(- 1, 4), M′(-1, 0), N′(- 3, 4)

A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.

Given that;

Triangle LMN is drawn with vertices at L(−4, −1), M(0, −1), N(−4, −3).

Now, We know that;

The rule of rotation 90° clockwise is,

⇒ (x, y) = (y, - x)

Thus, We get;

L = (- 4, - 1)

L'= (- 1,  4)

M = (0, - 1)

M' = (- 1, 0)

N = (- 4, - 3)

N' = (- 3, 4)

Hence, The image vertices of L′M′N′ if the preimage is rotated 90° clockwise are,

⇒ L′(- 1, 4), M′(-1, 0), N′(- 3, 4)

Answer:

Step-by-step explanation:

#7- Irrational; The adding of one 8 every time it well, gets to an 8, changes the pattern. For a decimal to be rational, it has to be steady, set from the beginning, and has to keep that pattern the whole time.

#9- C and E;

C. Pi (3.14…) is a continuous number that goes on forever and has no pattern to it, thus making it irrational.

E. Is one of those decimals that just decide to be different and difficult and have no repetition of patterns and goes on forever

#10- Just the square root of 15; Square root of 196 is 14; 5/9 is 0.5repeating… which I beliiieeeeve is rational?; and 7.27repeating have the same ongoing pattern

#11- 26, -3/2, 0, 9;

26 is a whole number; -3/2 would be -1.5 as a decimal, no extra numbers; 0 just… well… 0, so rational; and 9 is a whole number.

#12- No, it is irrational.; Same explanation as number 7, but instead of 8’s and 7’s it’s with 5’s and 6’s.
