need help with simplifying.

Answer:

10x+5y=120

y=-2x+24

Step-by-step explanation:

x=adult tickets

y=children tickets

120=total spent

10x+5y=120

5y=120-10x

y=(120/5)-(10x/5)

y=24-2x or y=-2x+24

Answer:

The circumference is 565.2 feet when the ferris wheel makes 4 rotations.

Step-by-step explanation:

Given that the diameter of the wheel is 45 feet.

That is:

[tex]d = 45\ feet[/tex]

We have to find the radius first

[tex]r = \frac{d}{2} = \frac{45}{2} = 22.5\ feet[/tex]

The circumference of the circular wheel for one rotation will be:

[tex]C = 2\pi r[/tex]

And for four rotations' circumference the circumference of one rotation will be multiplied with 4.

[tex]C = 2 * 3.14 * 22.5\\C = 141.3\ feet[/tex]

Total circumference:

[tex]C_T = 4C\\= 4 * 141.3\\=565.2\ feet[/tex]

Hence,

The circumference is 565.2 feet when the ferris wheel makes 4 rotations.

Answer:

The equation of line passing through (10,9) and having slope 3/2 is: [tex]y = \frac{3}{2}x-6[/tex]

Step-by-step explanation:

The slope intercept form of a line is given by:

[tex]y=mx+b[/tex]

We are given

Slope = m = 3/2

Point = (10,9)

Putting the value of the slope in the equation we get

[tex]y = \frac{3}{2}x+b[/tex]

b is the y-intercept. To find the y-intercept we have to put the point through which the line passes in the equation.

Putting (10,9) in the equation

[tex]9 = \frac{3}{2}(10) +b\\9 = 15+b\\b = 9-15\\b = -6[/tex]

Putting b=-6 in the equation

[tex]y = \frac{3}{2}x-6[/tex]

Hence,

The equation of line passing through (10,9) and having slope 3/2 is: [tex]y = \frac{3}{2}x-6[/tex]

Answer:

$ 14.25 this is probably the answer

The required two expressions are

(1-0.05)P

0.95 P

Step-by-step explanation:

First method : Here, the original price of pillow = P,

She marks them down 5%

Thus, the selling price = P - 5% of P = P - 0.05 P = (1-0.05)P

Second method :

Since, some number is 100% of itself,

⇒ 100 % = P

⇒ 1 % = P/100 = 0.01 P

Also, by decreasing 5 % from 100 %

The remaining percentage = 100 - 5 = 95%

⇒ 95 % = 95 × 0.01 = 0.95 P

We will use to midsegment theorem to solve this question.

Midsegment theorem,

Segment joining the midpoints of two sides of a triangle, is parallel and and measure the half of the the third side.

7). HE is the midsegment.

   HE = [tex]\frac{1}{2}(VU)[/tex]

         = [tex]\frac{1}{2}\times (80)[/tex]

         = 40

8). ED = [tex]\frac{1}{2}\times (TV)[/tex]

          = [tex]\frac{1}{2}(100)[/tex]

          = 50

9). HD = [tex]\frac{1}{2}(TU)[/tex]

    TU = 2(HD)

          = 2(80)

          = 160

10). TE = [tex]\frac{1}{2}(TU)[/tex]

           = [tex]\frac{1}{2}\times 160[/tex]

           = 80

As early as 4,000 years ago, but the first recorded use of a zero-like symbol dates to sometime around the third century B.C. in ancient Babylon.

Given that, the ancient Babylonians were writing fractions in 1800 BCE.

In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.

In fact, at first, fractions weren't even thought of as numbers in their own right at all, just a way of comparing whole numbers with each other.

The word fraction actually comes from the Latin "fractio" which means to break. To understand how fractions have developed into the form we recognize, we'll have to step back even further in time to discover what the first number systems were like.

From as early as 1800 BC, the Egyptians were writing fractions. Their number system was a base 10 idea (a little bit like ours now) so they had separate symbols for 1, 10, 100, 1000, 10000, 100000 and 1000000.

Hence, as early as 4,000 years ago, but the first recorded use of a zero-like symbol dates to sometime around the third century B.C. in ancient Babylon.

Answer:

D

Step-by-step explanation:

The amount of time that will take him to swim the remaining distance will be [2,000 (1/5)] / (3/4). Then the correct option is D.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

Speed is defined as the length traveled by a particle or entity in an hour. It is a scale parameter. It is the ratio of length to duration.

We know that the speed formula

Speed = Distance/Time

Mateo has proactively swum Four-fifths of the 2,000 meters he is swimming today. On the off chance that he keeps swimming at a speed of Three-fourths of a meter each second.

3/4 = 2,000 (1 - 4/5) / T

T = [2,000 (1/5)] / (3/4)

The amount of time that will take him to swim the remaining distance will be [2,000 (1/5)] / (3/4). Then the correct option is D.

Answer:

1.66

Step-by-step explanation:

Calculation to find the standard deviation for the random variable X of the number of students who work full time in samples of size

Using this formula

Standard deviation(X)=√np(1−p)

Where,

n represent the number of students=16

p represent the percentage of all students who work full time=22

Let plug in the formula

Standard deviation(X)=√16(0.22)(1−0.22)

Standard deviation(X)=√(3.52)(0.78)

Standard deviation(X)=√2.7456

Standard deviation(X)=1.656

Standard deviation(X)=1.66 (Approximately)

Therefore the standard deviation for the number of students who work full time in samples of size 16 will be 1.66

Answer:

1. 230, 219, 208, 197, 186.

2. Arithmetic, you are subtracting a constant rate, instead of an exponential rate.

3. Finite, the question says the farmer only took 10 trips, infinite would be much, much much more trips.

Step-by-step explanation:

1. The pattern is to subtract 11, so you just do this for 3 more times.

2. Geometric sequences could look something like 230-11=219. The you multiply by a random number like 2, then you subtract 219- (11x2), 219-22=197. This sequence does not do that.

3. It says in the question the farmer only does it for 10 more times.

Jayce earns 3 more points from gold stars than from silver stars.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Given that Jayce collected 80 silver stars and earned 160 points.

He collected 30 gold stars and earned 150 points.

Therefore,

The points per star Jayce earns from silver stars

160/80=2,

The points per star Jayce earns from gold stars

150/30=5

Hence, Jayce earns 3 more points from gold stars than silver stars.
