The ratio of the number of history majors to the number of mathematics majors is 3 to 2.

When two objects are related using numbers or amounts, the relationship is known as a ratio.

Let E be the number of English majors, H be the number of history majors, and M is the number of math majors.

Now,

There are twice as many English majors as history majors.

E = 2 × H

There are three times as many English majors as mathematics majors.

E = 3 × M

Now, let's assume E = 6.

Then,

6 = 2 × H

H = 3 and,

6 = 3 × M

M = 2

Therefore, the ratio of the number of history majors to the number of mathematics majors will be:

H: M = 3 : 2

The value of x is 17/12.

Given equation:-

3/4 = x - 4/6

We have to find the value of x from the given equation.

Rearranging the terms to find the solution, we can write,

x = 3/4 + 4/6

Least Common Multiple (LCM) of 4 and 6 = 12

Hence, we can write,

x = (3*3) + (2*4)/12

x = (9 + 8)/12

x = 17/12

Least Common Multiple (LCM)

In arithmetic, Least Common Multiple (LCM) of two or more numbers is the least positive number that can be divided by both the numbers, without leaving the remainder. It is also known as Lowest Common Multiple (LCM), Least Common Denominator, and Smallest Common Multiple.

The probability that the next chew Aaden removes from the bag will be a flavor other than apple is 24/31.

Probability is a branch of mathematics concerned with determining the likelihood of an event occurring. Probability assesses the likelihood of an event occurring and is equal to the number of favorable events divided by the total number of events.

Given:

Number of times Aaden performs the experiment = 31 times

A strawberry chew was selected 4 times.

An apple chew was selected 7 times.

A watermelon chew was selected 20 times.

So,

Probability of selecting a strawberry chew = 4/31

Probability of selecting an apple chew = 7/31

Probability of selecting a watermelon chew  = 20/31

So, the probability that the next chew Aaden removes from the bag will be a flavor other than apple i.e. it can be strawberry or watermelon chew.

Probability of selecting a strawberry chew + Probability of selecting a watermelon chew

Juniper spends $1300 out of the monthly income of $3250 on rent

Total income of Juniper = 3250 each month

Income is the money that an individual or organization receives in return for their services or goods. Depending on the context—such as taxation, financial accounting, or economic analysis—income may have a variety of definitions.

Percentage of expenditure on rent = 40%

Percentage of expenditure on food = 15%

Percentage of expenditure on utilities = 18%

The percentage for savings = 15%

Percentage of expenditure for personal items = 8%

Money Juniper spends on rent each month out of total income:

If she thinks that after 8 months, she will have spent around $75.00 total.  Dominique's estimate is not reasonable?

We have to make use of the given data to find whether amount of $75 which she estimated that she will spent after 8 months is reasonable

Total cost:

Total cost =$15.50  + 10 × $0.99 × 8

Total cost = $15.50 + 9.9 × 8

Total cost = $15.50 +$79.2

Total cost = $94.7

Hence,

$94.70 ≥ $75.00

Based on the above calculation the amount she estimated is not a reasonable amount because the total cost is greater that the estimated amount.

Therefore we can conclude that the estimate is unreasonable.

The estimate of the Dominique's is not reasonable.

Given that,
Dominique paid $15.50 to join an online music service. She purchases 10 songs each month at a cost of $0.99 per song. Dominique thinks that after 8 months, she will have spent around $75.00 total. Is Dominique's estimate reasonably is to be justified.

Here,
According to the question,
The total cost of the song for 8 months = 8 (0.99 x 10)
                                                            = $ 79.2
Total cost  = 15.50 + 79.2 = $94.7
Since the total cost exceeds Dominique's estimate so her estimate is not reasonable.

Thus, the estimate of the Dominique's is not reasonable.

length×width = 108

length + 2×width = 30

length = 30 - 2×width

using that in the first equation

(30 - 2×width)×width = 108

-2×width² + 30×width - 108 = 0

the general solution to such a quadratic equation like

ax² + bx + c = 0

is

x = (-b ± sqrt(b² - 4ac))/(2a)

so,

width = (-30 ± sqrt(30² - 4×-2×-108))/(2×-2) =

= (-30 ± sqrt(900 - 864))/-4 =

= (-30 ± sqrt(36))/-4 = (-30 ± 6)/-4

width1 = (-30 + 6)/-4 = -24/-4 = 6 ft

width2 = (-30 - 6)/-4 = -36/-4 = 9 ft

for width = 6 ft

length = 30 - 2×width = 30 - 12 = 18 ft.

The price of one candy box was $2.50 if the popcorn were of $3.20 and the total amount was $18.20.

The price of one candy box can be determined using an algebraic expression. An algebraic expression can be defined as one that consists of both numbers and letters.

As he ordered 6 boxes of candy and a bucket of popcorn and the popcorn was of $3.20 and the total was $18.20, an algebraic expression can be given as;

6(x) + 3.20 = 18.20

Here x is the price of one candy box

Solving for x;

6x = 18.20 - 3.20

6x = 15

x = 15 / 6

x = 2.50

Hence the price of one candy box is calculated to be $2.50.

Answer: 9

Step-by-step explanation:

I am assuming that the grid units equal 1 inch.

x = 60 * 3/20 = 180/20 = 9

The graph that matches the data on the table, representing the altitude and time of a hawk is the straight line graph in the second option.

A straight line graph is the graph of a linear function or relationship

From the he values in the given, we have;

The difference between the consecutive altitude values (the first difference) = 70 - 80 = 60 - 70 = 50 - 60 = -10 is constant

The difference between consecutive time values = 1

Therefore;

The relationship is a linear relationship and the graph is a straight line.

Slope of the graph = -10/1 = -10

The equation in point and slope form is therefore;

(y - 80) = (-10) × (x - 1) = -10•x + 10

(y - 80) = -10•x + 10

y = 80 + 10 - 10•x = 90 - 10•x

y = 90 - 10•x

The y–intercept = 90

The slope = -10

The correct option is therefore the second graph that has the altitude (ft) on the the vertical axis and the time (s) on the horizontal axis, with a straight line decreasing from left to right starting at the point (0, 90) on the left

Using the graph obtained value of k is 1/3. Option C is correct.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that

f(x) and g(x) = f(k-x),

The standard equation of a line is,

y = mx + b

The slope of the line for the coordinate points are (1, 2) and (1.5, 5)

m = 5-2/1.5-1

m = 3/0.5

m = 6

The y-intercept of the line is,

2 = 6(1) + b

2 - 6 = b

b = -4

As a result the obtained  equation is g(x) = 6x - 4

For the other coordinate point (3, 2) and (2, 0), the slope is

m = 0-2/2-3

m = -2/-1

m = 2

The y-intercept of the line is,

2 = 2(3) + b

2 - 6 = b

b = -4

As a result the obtained equation will be f(x) = 2x - 4.

Substitute xk at the place of x in the function as

f(xk) = 2(xk)- 4

If g(x) to f(k⋅x)

6x + 4 = 2(xk)- 4

6x = 2xk

6 = 2k
