The Algebra teachers at Blue Field High School need to buy new textbooks and calculators for the math department. The textbooks cost $105.00 each, and the calculators cost $120.00 each. If the teachers have $4,000 to spend and purchase 25 calculators, how many textbooks can they buy?

Answers

Answer 1

Answer: 9 textbooks

Step-by-step explanation:

25 x 120.00 = 3,000

4,000 - 3,000 = 1,000

9 x 105.00 = 945

1,000 - 945 = 55

The teacher can only buy 9 textbooks since she/he doesn't have enough money to get anymore.

Margot is sewing a ribbon on a seam along the perimeter of a square pillow. the side length of the pillow is 2x2 1 inches. she plans to make a similar pillow, including the ribbon, whose side length is 4x−7 inches. what expression can be used for the length of ribbon that she needs for both pillows, and what is the length if x = 3.5? 2x2 4x−6; 22.0 inches 2x2 4x−6; 32.5 inches 4(2x2 4x−6;) 88.0 inches 4(2x2 4x−6;) 130.0 inches

Answers

From the calculation, it is clear that the mathematical expression required for both pillows is given as: 4(2x2+4x−6;) 130.0 inches (Options D)


How do we arrive at the above result?

Recall side length is given as: 2x² + 1; and

The Ribbon's side length is: 4x -7.

To determine the length of ribbon required for the two pillows, we must state:

= 4 (2x² +1) + 4(4x-7)

Expanding the bracket since is common to both sides of the expression, we state:

= 4(2x² +1 + 4x -7).

Collecting like terms and resolving sums and differences, we have:

= 4(2x²+ 4x -6).

Step two

Recall that  length is given as x = 3.5 therefore,

substituting x in the equation, we have:

4 (2 * 3.5²) + 4 ((3.5)-6)

= 130 Inches.

What is the perimeter of a rectangle?

The measure of the boundary of the sides of a rectangle is called its perimeter. The perimeter of a rectangle is twice the sum of the sides of the rectangle.

[tex]P=2(a+b)[/tex]

Here, (l) is the length and (w) is the width of the rectangle.

John wants to build a fence around his pool. The pool is 22 feet long by 23 feet wide.  The fence is to be 15 feet from the edge of the pool from all the sides.

Thus, add 15 two times in length and width for both side of pool.  The length of the fence is,

[tex]l=23+15+15\\l=53[/tex]

The width of the fence is,

[tex]l=22+15+15\\l=52[/tex]

The perimeter of the fence is,

[tex]P=2(l+w)\\P=2(53+52)\\P=2(105)\\P=210\rm\; ft[/tex]

Thus, the total length of the fence which John wants to build a fence around his pool and 15 feet from the edge of the pool is 210 ft.

The completely factored form of the provided polynomial is  (p -2) (p+ 2) (p² +4). The option 4 is the correct option.

What is polynomial?

Polynomial equations is the expression in which the highest power of the unknown variable is n (n is a real number).

The polynomial equation given in the problem is,

[tex]p^4 - 16[/tex]

Let the factor form of the polynomial is f(p). Thus,

[tex]f(p)=p^4 - 16\\f(p)=p^4 - 2^4\\f(p)=(p^2)^2- (2^2)^2[/tex]

Using the formula of difference of squares, we get,

What is the value of x?

Answers

[tex]\bold{ANSWER:}[/tex]
x = 21
[tex]\bold{EXPLANATIONS:}[/tex]

Answer:

x = 21

Step-by-step explanation:

We can first notice that this is a right triangle. Meaning that we can apply the pythagorean theorem when finding the missing side.

Pythagorean Theorem : a^2+b^2=c^2

But, we already have the hypotenuse, so we have to solve for the side being "b". a and b being the sides next to the right angle. And c being the hypotenuse. Plug in the values.

20^2 + b^2 = 29^2

400 + b^2 = 841

Subtract 400 from both sides to get b^2 alone

-400            -400

b^2 = 441

Square root of each side to get b by itself

b = 21

This means the missing side is 21. Also meaning 21 is x.

x = 21

Using the formula for population density, it is found that the approximate area of Puerto Rico is of 3980 square miles.

What is the formula for population density?

It is given by the number of habitants divided by the area, that is:

[tex]D = \frac{H}{A}[/tex]

In this problem, we have that:

Puerto Rico has a population of [tex]H = 3.98 \times 10^6[/tex].The density is of about 1000 people per square mile, that is, [tex]D = 10^3[/tex].

Hence:

[tex]D = \frac{H}{A}[/tex]

[tex]10^3 = \frac{3.98 \times 10^6}{A}[/tex]

[tex]A = \frac{3.98 \times 10^6}{10^3}[/tex]

A = 3980.

About % are either female or have green eyes.
What percent of students in the survey are males who do not have green eyes? About % are males who do not have green eyes.
Find the sum of these two percentages. The sum of these two percents is %.

Answers

Answer:

% of students who are female or have green eyes: 51% or 45/88

% of students who are males without green eyes: 49% or 43/88

The sum of these two percentages: 100%

Step-by-step explanation:

Since there were 48 men surveyed and 40 women there were 88 students surveyed in total.

For the first part:

Since the students had to either be female, 40 students, or have green eyes, 5 male students, there would be a total or 45 students who were either female or had green eyes. Or 45/88 = 51%

For the second part:

Since the students had to be male and NOT have green eyes... take the total number of male students, 48 students, and subtract those with green eyes, 5 students, to get a total of 43 male students without green eyes. Or 43/88 = 49%
