The ratios of corn to lima beans are not equivalent.

What are equivalent ratios?

The ratios that are same when compared are called equivalent ratios. The equivalentity of two or more ratios can be determined by comparing them to one another. For instance, 1:2 and 2:4 have the same ratio.

In case of Gabby:

Ratio of corn to lima beans = 5/6 = 0.833

In case of Robert:

Ratio of corn to lima beans = 7/9 = 0.777

Notice that  0.833 ≠ 0.777

So, the ratios of corn to lima beans are not equivalent.

The domain of a function is composed by the set that contains all possible input values of the function.

In this problem, the function is a piece-wise function, as it has two different definitions. However, for each definition, the function is a linear function, which has no input restrictions, hence the domain of the function is composed by all real values.

The range of a function is composed by the set that contains all possible output values of the function.

The outputs of the function are obtained as follows:

Linear functions have no open spaces on it's domain, hence the interval that describes the range is given by:

5 qt of oil cost $6.25 when twelve quarts of oil cost $15.00.

The unitary approach is frequently helpful for multiplying and dividing by fractions because it is intuitive and, assuming the numbers add up, may be performed mentally. As a result, it might be a useful way to explain or introduce the often used written algorithms for fractions, especially division by a fraction. The unitary approach involves calculating the value of a single unit, from which we can calculate the values of the necessary number of units.

Given,

12 qt = 15.00

For one unit, we will use unitary method:

1 qt = 15/12

1 qt = 5/4

For 5 qt of oil:

5 qt = 5/4 × 5

5 qt = 25/4

Converting it in decimals:

5 qt = 6.25

5 qt of oil cost $6.25 when twelve quarts of oil cost $15.00.

The greatest common factor for 36m(r+t) and 9p(r+t)6 is 18(r+t).

According to the question,

We have the following two expressions:

36m(r+t) and 9p(r+t)6

Now, we will first solve the second expression:

54p(r+t)

Now, the greatest common factor means the greatest number and variables which can divide both the terms completely.

So, the common variables in both the terms are (r+t).

In 36 and 54, the greatest common factor is 18 because their respective product of factors are 2*2*3*3 and 3*3*3*2.

Now, the common factors in their product are 2*3*3. So, the greatest common factor or highest common factor is 18.

Hence, the greatest common factor for 36m(r+t) and 9p(r+t)6 is 18(r+t).

The dimensions which will give Margo the largest area is 6 m by 6 m

Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.

Given that, Margo has 24 meters of wood to build a fence around her garden. She wants to create the largest area possible

Let the length  be L and the width be W

So the perimeter equation is

2L + 2W = 24

2(L+W) = 24

L+ W= 12

L= 12-W

To find the largest area

area = L×W

area = (12-W) ×W

area= 12W- W²

A= -W²+ 12W

The vertex of the parabola is the point (h, k) where h=

= 6

to find the k part

k= (-6)² + 12(6)= 108 m²

The largest possible area is  108 m²

putting the value of W  in

L= 12-W

L= 12-6 = 6 m

Hence, the length and width is same, 6 m by 6 m

After 100 days there will be 33750 bees in the bee hive .

in the question ,

it is given that

number of bees in the bee hive when discovered = 20 bees

number of bees after 5 days = 29 bees

also given that the population of the bees increases exponentially ,

the exponential growth is denoted by the function ,

A = A₀(eᵃˣ)

where A is the population after x days ,

A₀ is the initial population , x is the days and a is the constant of proportionality .

Substituting the values in the exponential growth formula ,

we get

29 = 20 ([tex]e^{a\times5}[/tex])

29/20 = [tex]e^{a\times5}[/tex]

taking ln both the side

ln(29/20) = ln( [tex]e^{a\times5}[/tex])

5a = ln(29/20)

a = 0.07431

to find the population after 100 days , we substitute x = 100,

we get

A = 20*  [tex]e^{0.07431\times100}[/tex]

A = 33749.88

A ≈ 33750

then subtract 4 from 6 and you get -2.

This can be solved using proportions. Aiden needs to make 3 trips to walk 9 kilometers.

What is a proportion?

Two numerical sequences, generally experimental data, are said to be proportional or directly proportional if their corresponding elements have a constant ratio, which is known as the coefficient of proportionality or proportionality constant. Two sequences are inversely proportionate if the product of their respective elements is constant, also known as the coefficient of proportionality. This notion is frequently extended to related changing numbers, which are typically referred to as variables. For instance, if an item moves at a constant speed, the distance traveled is exactly proportional to the time spent traveling, with the speed serving as the proportionality constant.

For 2 trips, Aiden walks 6 kilometers

So, for 9 kilometers to walk he need 'x' trips (let)

Then they are in proportion, i.e.,

2/6 = x/9

or, x = (2/6)9

or, x = 3

Hence, Aiden needs 3 trips to walk a total of 9 kilometers.

Explanation

Rule: The three inside angles of any triangle always add to 180 degrees.

In this case we can say the following

(x+43)+(x+66)+(79) = 180

2x+188 = 180

2x = 180-188

2x = -8

x = -8/2

It is necessary to collimate the light source before using the prisim to  disperse the light so that the light rays entering the prisim are parallel.

What is collimate?

Collimator is a tool for converting a point source's divergent radiation into a parallel beam. To perform specific measurements in spectroscopy, geometrical optics, and physical optics, the light must be collimated.

An optical collimator is made up of a tube with a convex lens at one end and a variable aperture at the other end that is located in the lens' focal plane. To examine the image without parallax, radiation entering the aperture exits the collimator as a parallel beam.

Therefore collimation is needed for the light rays entering the prism to be parallel.

Every hour, the medicine concentration decays by a factor of 0.09.

An exponential function simply refers to a mathematical function whose values are generated by a constant that is raised to the power of the argument. Mathematically, an exponential function can be modeled or represented by using this equation:

f(x) = abˣ

Where:

At the initial time (t), the medicine concentration is given by this exponential function:

C(t) = 61 × (0.96)^t

Note: One (1) hour is equal to sixty (60) minutes.

After an hour, the medicine concentration is given by this exponential function:

C(t + 60) = 61 × (0.96)^{t + 60}

Therefore, the rate of change every hour in the medicine concentration would be calculated as follows:

Decay factor = [C(t + 60)/C(t)]

Decay factor = [61 × (0.96)^{t + 60}]/61 × (0.96)^t

Decay factor = (0.96)^t

Decay factor = (0.96)^60

Decay factor = 0.0864 ≈ 0.09.

The equation for the sentence below is x - 23 = 28.

The solution to the equation is x = 5.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Therefore, the sum of a number(x) and - 23 is 28 can be represented with an equation as follows:

The unknown number is x.

Hence,

x + (-23) = 28

Therefore, the equation from the sentence above is  x - 23 = 28.

Now, let's solve the equation for x as follows;

x - 23 = 28

add 23 to both sides of the equation

x - 23 + 23 = 28 - 23

x = 5

The answer for the part 1 I=1500, part 2: R = 2.5% and part 3: T=1year, using Simple interest, Rate and Time.

What is simple interest and Rate?

A quick and simple way to figure out interest on money is to use the simple interest technique, which adds interest at the same rate for each time cycle and always to the initial principal amount. Any bank where we deposit our funds will pay us interest on our investment. One of the different types of interest charged by banks is simple interest. Now, before exploring the idea of basic curiosity in further detail,

The formula for simple interest is:

S = p*t*r/100

where P is the principal amount of money, R is the interest rate as a decimal, T is the time.

Given part 1: P=$3000,R=10%,T=5 yrs.

I = 3000*10*5/100 = 1500

part 2: P=$8000,T=4 yrs,I=$800

R= 800*100/8000*4 = 2.5%

part3: P=$2000,R=20%,I=$400

So T = 400*100/2000*20 = 1 year

Hence the answer for the part 1 I=1500, part 2: R = 2.5% and part 3: T=1year
