Step-by-step explanation:

The number of dimes is 13.

The system of equation for the situation is as follows;

x + y = 24

0.1x + 0.05y = 1.85

The coins are 24.

Therefore, they are all dimes and nickel.

Total value of the coins is $1.85.

Hence, let

x = number of dimes

y = number of nickels

Therefore,

x + y = 24

0.1x + 0.05y = 1.85

0.1x + 0.1y = 2.4

0.1x + 0.05y = 1.85

0.05y = 0.55

y = 0.55 / 0.05

y = 11

x = 24 - 11

x = 13

If the radius of the smaller gear is 1.5 inches and the radius of the large gear is 4.5 inches then the bicycles can travel a distance of 62.83 inches.

Given radius of the small gear=1.5 inches and radius of the larger gear=4.5 inches.

Number of rotation of the small gear for each rotation of the larger gear=4.5/1.5=3

Distance which the bicycle can travel=3*2πr.

=3*2*π*10

=60π inches.

Difference in distance travelled=60π inches-40π inches.

=20π inches

put π=3.14

=20*3.14

=62.83 inches.

Hence the distance that the bicycle travels is 62.83 inches if the radius of smaller gear is 1.5 inches and radius of the larger gear is 4.5 inches.

Answer:

A' = (3, 6)

B' = (9, -3)

C' = (-12, -6)

Step-by-step explanation:

you can mulitply both the x and y coordinates of each point by the scale factor (3)

point (1, 2) becomes point (3, 6)

(3, -1) becomes (9, -3)

(-4, -2) becomes (-12, -6)

hope this helps!! have a lovely day :)

{this is why whoever wrote the problem gave that hint--you can follow through on that logic, but just remember that it has to be a scaled version of the original figure--so the ratios between points (and x/y values) must be consistent}

The company cannot build  10 child bikes and 12 adult bikes No, because the bike order does not meet the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100 , Option A is the correct answer.

System of inequality represent system of inequalities that satisfies common condition.

It is given that

Each child bike requires 4 hours to build and 4 hours to test.

Each adult bike requires 6 hours to build and 4 hours to test.

Total building hours = 120

Total testing hours = 100

If c represents child bikes and a represents adult bikes, can the company build 10 child bikes and 12 adult bikes in a week.

6a + 4c ≤ 120

4a +4c ≤100

On solving this system of Inequality

a ≤ 10

which is less than required , and so

No, because the bike order does not meet the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100

Step-by-step explanation:

The domain of an exponential function is all real numbers.

The range of an exponential function that has not been vertically shifted is [tex](0, \infty)[/tex].

The domain of the function is all the real numbers and the range of the function is set of all positive real numbers

The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.

The range is the set of outputs of a relation or function. In other words, it's the set of possible y values. Recall that ordered pairs are of the form (x,y) so the y coordinate is listed after the x. The output is listed after the input.

Given data ,

The domain of the given function is all real numbers. In other words, there are no restrictions on the possible values of x that we can plug into the function.

To see why, note that we can raise any real number to any power, so there are no values of x that are off-limits for this function.

The range of the function is all positive real numbers.

This is because the base of the exponential function is 5, which is positive, and raising 5 to any power results in a positive number. Multiplying a positive number by 3 also results in a positive number, so the function output is always positive.

Hence , we can write the domain and range of the function as:

Domain: all real numbers

Range: y > 0 (all positive real numbers)

Let n represent number of revolutions.

We are asked to find the number of revolutions it will take for a car wheel of diameter 30 in. to travel a distance of one mile.

1 mile = 63360 inches.

We will use circumference of circle formula to solve our given problem.

Circumference = pi*d , where, D represents diameter of circle.

Now, we will set the product of n and circumference of circle equal to 63360 inches as:

Colorado and Boston have 263 and 219 days of sunshine respectively.

Let the number of days of sunshine in Colorado is x and the number of days of sunshine in Boston is y.

Total number of days of sunshine=482

Also, the number of days of sunshine in Colorado is 1.2 times the number of days of sunshine in Boston.

So, the equation is formed as follows:

x+y=482  -(1)

The other equation is formed as:

x=1.2y  -(2)

Substitute the value x from equation (2) in (1),

1.2y+y=482

2.2y=482

y=482/2.2

y=219

Substitute the value of y in equation (1),

Answer:

60 or 60:1 (Depending on the answer choices)

Step-by-step explanation:

160 feet = 1920 inches (160 * 12)

[tex]\frac{1920}{32} = \frac{60}{1}[/tex]

The scale factor required will be 1:60 or 60:1 (actual:movie or movie:actual).

The scale factor is the simplest ratio between the actual and the model's size of the same object.

In the question, we are informed that in a movie, a child who was 32 inches tall was ''blown up'' to be 160 feet tall.

We are asked to determine the scale factor needed for the props in the movie.

To find the scale factor, we first find the size of the child in the movie in inches.

Size = 160 feet = 160*12 inches = 1920 inches.

Now, the scale factor is calculated as the ratio of the actual size to the size in the movie, that is,

Scale factor = 32:1920 = 32/1920 = 1:60.

Therefore, the scale factor required will be 1:60 or 60:1 (actual:movie or movie:actual).

The probability that there will be no customers arriving at a checkout counter in the next minute is 0.16530.

The number of customers arriving per minute at the checkout counter of a grocery store is following Poisson Distribution.

A Poisson Distribution over a variable X, having a mean λ, has a probability for a random variable x as [tex]P(X = x) = e^{-\lambda} \frac{\lambda^{x}}{x!}[/tex] .

In the question, we are asked to find the probability that no customer arrives at the checkout, hence we put x = 0, and the mean number of customers per minute (λ) = 1.8.

Substituting the values of x and λ in the equation, we get:

[tex]P(X = 0) = e^{-1.8} \frac{1.8^{0}}{0!}[/tex] ,

or, [tex]P(0) = e^{-1.8} = 0.16530[/tex] .

x represents the number of tickets of level 1 and y represents the number of tickets of level 2 in the system given that there are 10,000 seats, level 1 tickets are $50 each, and level 2 tickets are $150 each and equation representing the situation:x + y = 10,000, 50x + 150y = 75,000. This can be obtained by understanding the question and observing the equations.

Given that total number of seats is 10,000 and there are two levels pricing.

Thus by observing the equation, x + y = 10,000,

10,000 is the sum of 2 variable which obviously will be the number of tickets in level 1 and number of tickets in level 2.

Since there are two level pricing,

50x + 150y = 75,000 represent the addition of total cost of tickets of level 1 and 2.

Hence x represents the number of tickets of level 1 and y represents the number of tickets of level 2 in the system given that there are 10,000 seats, level 1 tickets are $50 each, and level 2 tickets are $150 each and equation representing the situation:x + y = 10,000, 50x + 150y = 75,000.
