(a) The respondents who chose silver 2.3 times more than red , and

(b) the respondents who chose either silver or black are 3.8 times more than who chose red .

In the question ,

a table is given which shows popular sports cars colors in North America .

Part(a)

portion of respondents who chose silver = 0.20  ,

portion of respondents who chose red = 0.09 ,

the number of times more respondents chose silver than red = 0.20/0.09

= 20/9

= 2.22222

On rounding to the nearest tenth

≈ 2.3

Part(b)

portion of respondents who chose black = 0.14 ,

portion of respondents who chose either black or silver = 0.20 + 0.14

= 0.34

number of times more respondents chose either silver or black than red

= 0.34/0.09

= 3.7777777

rounding to the nearest tenth

≈ 3.8

Therefore , (a) The respondents who chose silver 2.3 times more than red , and

(b) the respondents who chose either silver or black are 3.8 times more than who chose red .

The given question is incomplete , the complete question is

Use the table that shows popular sports cars colors in North America

(a) how many times more respondents to silver than red round to the nearest 10th if necessary.

(b) How many times more respondents chose either silver or black than red?   Round to the nearest tenth if necessary.

The domain and the range of the piece-wise function are given as follows:

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:

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

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

The required time taken by the sofia is 15.75 minutes.

Work is defined as the efficiency of the person to do a particular work in the certain period of time. Work is directly proportional to the efficiency and inversely proportional  to time.

Formula, work = efficiency/time

According to the given data in the question:

Let efficiency of sofia be 1, then efficiency of elsa is 3.

We have time for 21 minutes

total work =efficiency/time

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

Therefore, the value of x is 5

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).

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

The shares of $2.25 are 200 and the shares of $2.75 are 700.

According to the question,

We have the following information:

An investor bought 700 shares of stock, some at $2.25 per share and some at $2.75 per share. And the total cost was $1825.00.

Now, let's take the shares of $2.25 to be x and the shares of $2.75 to be y.

So, we have the following expression:

x+y = 700

x = 700-y ....(1)

2.25x+2.75y = 1825 ...(2)

Putting the value of x from equation 1:

2.25(700-y)+2.75y = 1825

1575-2.25y+2.75y = 1825

1575+0.5y = 1825

0.5y = 250

y = 250/0.5

y = 500

Now, putting the value of y in equation 1:

x = 700-y

x = 700-500

x = 200

Hence, the shares of $2.25 are 200 and the shares of $2.75 are 700.

Answer:

x = -4

The x+43 angle is 39 degrees

The x+66 angle is 62 degrees

======================================================

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

x = -4

Step-by-step explanation:

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
