To find the number of computers given the ratio of computers to desks and the number of desks, set up a proportion and solve for the unknown value.

In this question, we are given the ratio of computers to desks, which is 2 to 3. We are also given the number of desks, which is 15. To find the number of computers, we can set up a proportion:

2 computers / 3 desks = x computers / 15 desks

By cross-multiplying and solving for x, we find that there are 10 computers.

The student must make monthly payments of $1,020.63 to repay the $3,000 loan with $61.88 in interest over 3 months.

The student has borrowed $3,000 for 3 months and the interest incurred on this loan is $61.88. To find the monthly payment, we need to add the total interest to the principal borrowed and then divide it by the number of payments (which is 3 in this case).

The total repayment amount is calculated as $3,000 principal + $61.88 interest = $3,061.88.

Now, we divide the total repayment amount by the number of monthly payments:

Monthly Payment = Total Repayment Amount / Number of Payments

Monthly Payment = $3,061.88 / 3

Monthly Payment = $1,020.63

Therefore, the student will need to make monthly payments of $1,020.63 to repay the $3,000 loan over 3 months.

Final answer:

Using the Triangle Inequality Theorem and given a perimeter of 20 units for a triangle with integer side lengths, the maximum length of one side is found to be 15 units.

Explanation:

To determine the maximum length of one side of a triangle with integer side lengths and a perimeter of 20 units, we must apply the Triangle Inequality Theorem. This theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. Given a perimeter of 20 units, if we denote the longest side as x, and the other two sides as y and z, we must satisfy two conditions:

x + y + z = 20 (perimeter condition)

x < y + z (Triangle Inequality Theorem)

Since the triangle has different integer side lengths, the largest x can be is when y and z are consecutive integers because this allows for the largest possible x. If we try the smallest integers, 1 and 2, for y and z, their sum is 3. To satisfy the triangle inequality, the largest possible integer for x would be 20 - 1 - 2 = 17. However, this does not satisfy the inequality x < y + z, because 17 is not less than 3.

Next, we increase y and z to 2 and 3, respectively, which sums up to 5. Thus, for x, we have 20 - 2 - 3 = 15. Since 15 is less than 2 + 3, it satisfies the condition required by the Triangle Inequality Theorem. Therefore, the maximum length of any one side of the triangle is 15 units.

To solve this question:

Doing this, we get that the system is, with the 3 equations:

[tex]9a^2 + 3b + c = 8[/tex]

[tex]75a + 15b + 3c = 20[/tex]

[tex]36a + 6b + c = 5[/tex]

Equation of a parabola:

A parabola is a second degree polynomial, having an standard equation of:

[tex]y = ax^2 + bx + c, a \neq 0[/tex]

Point (3,8)

This means that when [tex]x = 3, y = 8[/tex]. So

[tex]y = ax^2 + bx + c, a \neq 0[/tex]

[tex]8 = a\times3^2 + 3b + c[/tex]

[tex]9a^2 + 3b + c = 8[/tex]

Thus, [tex]9a^2 + 3b + c = 8[/tex] is the first equation.

(5,20/3)

This means that when [tex]x = 5, y = \frac{20}{3}[/tex]. Thus

[tex]y = ax^2 + bx + c, a \neq 0[/tex]

[tex]\frac{20}{3} = a\times5^2 + 5b + c[/tex]

[tex]25a + 5b + c = \frac{20}{3}[/tex]

[tex]75a + 15b + 3c = 20[/tex]

Thus, [tex]75a + 15b + 3c = 20[/tex] is the second equation.

(6,5)

This means that when [tex]x = 6, y = 5[/tex]. Thus

[tex]y = ax^2 + bx + c, a \neq 0[/tex]

[tex]5 = a\times6^2 + 6b + c[/tex]

[tex]36a + 6b + c = 5[/tex]

Thus, [tex]36a + 6b + c = 5[/tex] is the third equation.

After all, the system of equations is:

[tex]9a^2 + 3b + c = 8[/tex]

[tex]75a + 15b + 3c = 20[/tex]

[tex]36a + 6b + c = 5[/tex]

Inequalities are used to represent unequal expressions.

[tex]\mathbf{(a)\ c + 7 \le 3}[/tex]

Subtract 7 from both sides

[tex]\mathbf{c \le -4}[/tex]

The above means that:

Hence, graph (b) represents [tex]\mathbf{c + 7 \le 3}[/tex]

[tex]\mathbf{(b)\ c - 3 > 1}[/tex]

Add 1 to both sides

[tex]\mathbf{c > 4}[/tex]

The above means that:

Hence, graph (c) represents [tex]\mathbf{c - 3 > 1}[/tex]

[tex]\mathbf{(c)\ c - 7 < 3}[/tex]

Add 7 to both sides

[tex]\mathbf{c < 10}[/tex]

Emma should have used division to represent the quotient of six and x, and she should have used parentheses to show that -2 is multiplied by (4.5 - x). Hence the correct options are 1 and 5.

Emma made two errors in translating the statement "the quotient of six and a number, x, is the same as negative two times the difference of x and 4.5." First, instead of representing the quotient of six and x, she incorrectly wrote 6x, which implies multiplication rather than division. The correct representation should be 6/x.

Second, Emma failed to use parentheses to show that -2 is multiplied by the difference of x and 4.5. The correct expression should be -2(x - 4.5) to ensure proper order of operations. These errors impact the accuracy of the translated equation, and correcting them would yield a more faithful representation of the original statement. Hence the correct options are 1 and 5.
