Step-by-step explanation:

If  she will need to start 2 inches in then total length of ribbon is 25.2 needs.

In the given question, Genevieve is cutting a 60-inch piece of ribbon into a ratio of 2:3.

2 inches are frayed at one end of the ribbon, she will need to start 2 inches.

Total length of ribbon is 60-inches.

Ratio of pieces = 2:3

Let the one piece length is 2x and other piece is 3x.

So 2x+3x=60

5x=60

Divide by 5, we get

x = 12

Now the length of one piece = 2*12 = 24

Other piece length = 3*12 = 36

Since, 2 inches are frayed at one end of the ribbon, she will need to start 2 inches.

So

=2* (3/2+3)

=2* 3/5

=1.2 inches

So the total length = 24+1.2 = 25.2

The completed equation is a/u = b/t = c/s = d/r.

Similar figures are those that share the same shape but differ in size. To put it another way, two figures are said to be comparable when they have many characteristics yet may not be exactly the same.

Two rectangles must have proportional sides in order for them to be identical (form equal ratios). The two shorter sides should be proportionately equal to the two longer sides.

a/u = b/t = c/s = d/r is the solution to the problem.

Similar rectangles are shown.

These related rectangles' sides are proportionate.

The sides are now equal and in proportion:

a/u = b/t = c/s = d/r.

a/u = b/t = c/s = d/r is the solution to the problem.

To find out the number of positive integers that are less than or equal to 500 and are divisible by 2, 3, or 5, we will use the principle of inclusion and exclusion.

How many positive integers less than or equal to 500 are divisible by 2 or 3 or 5? There are 250 numbers that are divisible by 2, less than or equal to 500. There are 166 numbers that are divisible by 3, less than or equal to 500. There are 100 numbers that are divisible by 5, less than or equal to 500.

Using inclusion and exclusion principle, we get that the total number of positive integers that are less than or equal to 500 and divisible by 2 or 3 or 5 is:250 + 166 + 100 - 83 - 50 - 33 + 16= 366 numbers. So, there are 366 positive integers that are less than or equal to 500 and are divisible by 2 or 3 or 5.

Answer:

<BAC = 80

Step-by-step explanation:

All triangle angles equal 180

<BAC = x

x + 50 + 50 = 180

x + 100 = 180

x = 180 - 100

x = 80

To estimate the sum of the entire series with an error of less than 0.001, more than the obtained value of n terms should be used.

The alternating series estimation theorem provides a way to determine the number of terms required to estimate the sum of an alternating series with a desired level of accuracy. According to the theorem, the error in the estimation is bounded by the absolute value of the first neglected term.

In this case, we want the error to be less than 0.001. Let's denote the nth term of the series as a_n. The error term, E, can be expressed as the absolute value of the (n+1)th term:

E = |a_(n+1)| = |(-1)^((n+1)+1)/((n+1)+3√(n+1))^3| = 1/((n+4√(n+1))^3).

To ensure that the error is less than 0.001, we need:

1/((n+4√(n+1))^3) < 0.001.

By solving this inequality, we can determine the value of n. However, since it involves a cubic term, it might not be straightforward to solve analytically. It is recommended to use numerical methods or software to solve this inequality and find the minimum value of n that satisfies the condition.

Therefore, to estimate the sum of the entire series with an error of less than 0.001, more than the obtained value of n terms should be used.

Answer:

Step-by-step explanation:

a)

The total amount coffee beans

b)

The total amount of market price

Answer:

a)   750a + 1200r = 1000000

b)   1065a + 876r = 1000000

Step-by-step explanation:

Define the variables:

Part (a)

Given:

If the plantation yields 1,000,000 kg of coffee:

⇒ 750a + 1200r = 1000000

Part (b)

Given:

If the price of Arabica beans is $1.42 per kg, and Arabica yields about 750 kg per hectare, then the price per hectare of Arabica coffee beans is:

⇒ $1.42 × 750 = $1065 per hectare

If the price of Robusta beans is $0.73 per kg, and Robusta yields about 1200 kg per hectare, then the price per hectare of Robusta coffee beans is:

⇒ $0.73 × 1200 = $876 per hectare

Therefore, if the plantation produces coffee worth $1,000,000:

⇒ 1065a + 876r = 1000000

The total rice flour is 5.6 ounces can be bought for $2.80 at that cost.

There are 16 ounces in a pound. So $8/16 ounces = $0.50 per ounce. Therefore, $2.80/$0.50 = 5.6 ounces of rice flour can be bought for $2.80 at that cost.

The calculation was determining how many ounces of rice flour can be bought for $2.80 at a cost of $8 per pound. It converts the cost per pound to cost per ounce and then divides the total cost by the cost per ounce to find the number of ounces that can be bought.

This type of calculation can be applied in daily life when comparing prices of different units of measurement (e.g. pounds to ounces) or when trying to stay within a budget when purchasing items. It can be used to compare prices and help make informed decisions about what to buy.

Answer:

Domain:  (-∞, 1) ∪ (1, ∞)

Range:  (-∞, -2) ∪ (2, ∞)

Yes, it's a function.

Step-by-step explanation:

Information

The domain of a function is the set of all possible input values (x-values).

From inspection of the given graph:

Therefore, the domain is all values of x except x = 1:

The range of a function is the set of all possible output values (y-values).

From inspection of the given graph:

Therefore, the range is all values of y except between -2 and 2:

A function is a special type of relationship where each input (x-value) is related to exactly one output (y-value).

From inspection of the graph, as the two points where x = 1 are not included, each value in the range (y-values) corresponds to exactly one value in the domain, and so it is a one-to-one function.

Answer:

y = $30x ;

1 : $30

Step-by-step explanation:

Given that :

$60 is saved in electricity bill for every 2 panels

Model, y

Amount saved, y = amount saved per panel * number of panels

Let number of panels = x

Hence, total amount saved, y ;

y = $30x

Ratio of panels to money saved :

Number of panels : amount of money saved

2 : $60

1 : $30

Hence, $30 is saved in cost of electricity bill per 1 solar panel purchased.

Answer:

(2,1)

Step-by-step explanation:

When we translate to the right, we are simply adding a value to the x axis value corresponding to the units of translation

We have the translation by 1 unit, so we are to add 1 to the value of the x-coordinate

Thus, we have this as ;

(-3 + 1, 1)

= (-2,1)

When we reflect a point (x,y) over the y-axis, its new coordinates become (-x,y)

Applying this to what we have above, the coordinate of the final point will be (2,1)
