A rectangular box has a length that is 4 feet longer than its width, w.
Write an algebraic expression, in simpliest form, to find the perimeter of the box.
Step-by-step explanation:
The length of the rectangle is 4 feet longer than its width w, which means the length is w + 4
The perimeter of a rectangle is the sum of the lengths of all four sides which can be expressed as:
Perimeter = 2(length + width)
Substituting w + 4 for length and w for width, we get:
Permiter = 2(w + 4 + w)
Simplifying this expression, we get:
Perimeter = 2(2w + 4)
Perimeter = 4w + 8
Therefore, the algebraic expression to find the perimeter of the rectangular box is 4w + 8

I’m thinking of three numbers: X, Y, and Z. We have X ≤ Y ≤ Z. The median of the
three numbers is 90, the mean of the three numbers is 92, and the range of the three
numbers is 6. What are the values of X, Y, and Z? Show your work
The X, Y, and Z values are 84, 90, and 90, respectively. To answer this question, we need to understand the meaning of the words "median", "mean" and "range".
What is median?Median is the middle number of a set of numbers - it is the number in the middle when the numbers are ordered from smallest to largest.
Since the median is 90, this means that Y (the mean number) is 90. Since the average is 92, this means that the sum of the three numbers is 276 (92 x 3). The interval is 6, which means that the difference between the largest number and the smallest number is 6.
To solve for X and Z, we can use the equation X Y Z = 276. We know that Y is 90, so we can plug 90 into Y:
X 90 Z = 276
Then we can subtract 90 from both sides to find the value of X and Z:
X Z = 186
Since the range of the three numbers is 6, this means that X and Z must be 6 plus. The only two numbers that differ by six and add up to 186 are 84 and 90.
Therefore the X, Y, and Z values are 84, 90, and 90, respectively.

the diameter of a spherical balloon is 21.6 centimeters
The parameter for determining the diameter of an object depends on the specific object being measured. Here are some examples of parameters that can be used to determine diameter the answer is 5276.7 cm3. Thus, option D is correct.
What are the parameter for determining the diameter?The formula for the volume of a sphere is [tex]V = (4/3)πr^3[/tex] , where r is the radius of the sphere.
Since we are given the diameter of the sphere, we can find the radius by dividing the diameter by 2:
[tex]r = 21.6 cm / 2 = 10.8 cm[/tex]
Substituting this value into the formula, we get:
[tex]V = (4/3)\pi(10.8)^3[/tex]
[tex]= 4.18879 \times (10.8)^3[/tex]
[tex]= 5276.794 cm^3[/tex]
Rounding to the nearest tenth, we get:
[tex]V \approx 5276.8 cm^3[/tex]

Ezra works two summer jobs to save for a laptop that costs at least $1100 he charges $15/hr to mow lawns and $10 an hour to walk dogs. Recall the inequality that represents this situation: 15x + 10y >_ 110
is (60,20) a solution? How do you know? What does this power represent?
Answer:
The inequality that represents this situation is 15x + 10y ≥ 1100, since Ezra needs to earn at least $1100 to buy the laptop.
To check if (60, 20) is a solution to this inequality, we need to substitute x = 60 and y = 20 into the inequality and see if it is true:
15(60) + 10(20) ≥ 1100
900 + 200 ≥ 1100
1100 ≥ 1100
Since 1100 ≥ 1100 is true, this means that (60, 20) is a solution to the inequality. This means that if Ezra works 60 hours mowing lawns and 20 hours walking dogs, he will earn enough money to buy the laptop.
The point (60, 20) represents the combination of hours worked for mowing lawns (x) and walking dogs (y) that will result in Ezra earning enough money to buy the laptop. The x and y values are the inputs or variables, while the inequality 15x + 10y ≥ 1100 is the constraint that must be satisfied. The solution (60, 20) is the output or result of the system of inequalities, and represents the combination of hours worked that will satisfy the constraint.

State any excluded values of a domain and identify the type of break in the graph at the value of x
f(x)=x+7/x-2
Answer:
The excluded value in the domain is x = 2 because the denominator of the rational function becomes zero at this value of x, which results in division by zero.
At x = 2, there is a vertical asymptote, which means that the graph of the function approaches positive or negative infinity as x approaches 2 from either side.

FACE is a rhombus the following measures are 9. CY= 39.05 cm, 10. FC= 40 cm, 11. AY ≈ 39.05 cm, 12. YE = 20 cm, 13. FA ≈ 39.05 cm, 14. AC ≈ 48.99 cm, 15. Perimeter ≈ 156.20 cm.
Describe Rhombus?A rhombus is a quadrilateral with all four sides of equal length. It is also known as a diamond or a lozenge. The opposite sides of a rhombus are parallel to each other, and the diagonals of a rhombus bisect each other at a right angle. Additionally, the diagonals of a rhombus are perpendicular bisectors of each other. This means that they split the rhombus into four congruent right triangles.
Since FACE is a rhombus, all four sides are equal in length. Additionally, the diagonals bisect each other at a right angle, so we can use the Pythagorean theorem to find the lengths of various segments in the figure.
9. CY: Since FC is a diagonal of the rhombus, it bisects angle FCE. This means that triangle FCY is a right triangle with FC as the hypotenuse and FY and CY as the legs. Using the Pythagorean theorem, we can find that CY is:
CY² = FC² - FY²
CY² = 40² - 15²
CY² = 1525
CY ≈ 39.05 cm
10. FC: We already know that FC = 40 cm, since it is one of the diagonals of the rhombus.
11. AY: By symmetry, we know that AY is equal in length to CY, so AY ≈ 39.05 cm.
12. YE: Since YE is half of EA, and we know that EA = 40 cm, we can find that YE = 20 cm.
13. FA: Since all four sides of the rhombus are equal, FA has the same length as CY and AY, so FA ≈ 39.05 cm.
14. AC: Since AC is a diagonal of the rhombus, it bisects angle EAF. This means that triangle ACE is a right triangle with AC as the hypotenuse and AE and EC as the legs. We can use the Pythagorean theorem to find that:
AC² = AE² + EC²
AC² = 40² + 2*(YE)²
AC² = 40² + 2*(20²)
AC² = 1600 + 800
AC² = 2400
AC ≈ 48.99 cm
15. Perimeter of the given rhombus FACE: Since all four sides of the rhombus are equal, we can find the perimeter by multiplying the length of one side by 4. Using any of the values we found above for the length of a side, we get:
Perimeter = 4*CY
Perimeter ≈ 156.20 cm

Answer:
9. CY = 15 cm
10. FC = 30 cm
11. AY = 20 cm
12. YE = 20 cm
13. FA = 25 cm
14. AC = 25 cm
15. Perimeter FACE = 100 cm
Step-by-step explanation:
In a rhombus:
All sides of a rhombus are congruent.The diagonals are perpendicular bisectors of each other.Given the diagonals bisect each other, Y is the point of intersection, and CY = 15 cm, then:
[tex]\begin{aligned}\overline{FY} &= \overline{CY} \\&= 15 \; \sf cm\end{aligned}[/tex]
[tex]\begin{aligned}\overline{FC} &= \overline{FY} + \overline{CY} \\&= 15 + 15 \\&= 30 \; \sf cm\end{aligned}[/tex]
Given the diagonals bisect each other, Y is the point of intersection, and EA = 40 cm, then:
[tex]\begin{aligned}\overline{AY}&=\overline{EA} \div 2\\&=40 \div 2\\&=20\; \sf cm\end{aligned}[/tex]
[tex]\begin{aligned}\overline{YE} &= \overline{AY} \\&= 20 \; \sf cm\end{aligned}[/tex]
As the diagonals bisect each other at 90°, m∠FYA = 90°. Therefore, triangle FYA is a right triangle.
As we know the lengths of legs of the triangle FYA, we can use Pythagoras Theorem to calculate the length of the hypotenuse (FA).
[tex]\begin{aligned}\overline{FY}^2+\overline{AY}^2&=\overline{FA}^2\\15^2+20^2&=\overline{FA}^2\\225+400&=\overline{FA}^2\\625&=\overline{FA}^2\\\overline{FA}&=\sqrt{625}\\\overline{FA}&=25\; \sf cm\end{aligned}[/tex]
As the sides of a rhombus are equal in length:
FA = EC = AC = FE = 25 cmThe perimeter of rhombus FACE is the sum of its side lengths:
[tex]\begin{aligned}\sf Perimeter&=\overline{FA}+\overline{EC}+\overline{AC}+\overline{FE}\\&=25+25+25+25\\&=100\; \sf cm\end{aligned}[/tex]

You have been asked to build a scale model of your school out of toothpicks. Imagine your school is 30 feet tall. Your scale is 1 ft:1.68 cm.
If a toothpick is 6.3 cm tall, how many toothpicks tall will your model be?
The model will be
toothpicks tall.
Your mother is out of toothpicks, and suggests you use cotton swabs instead. You measure them, and they are 7.6 cm tall. How many cotton swabs tall will your model be? If necessary, round your answer to the nearest whole number.
The model will be approximately
cotton swabs tall.
Answer:
8 toothpicks
7 cotton swabs
Step-by-step explanation:
Since the school is 30 feet tall and the scale is 1 ft : 1.68 cm, 30 feet will require a scale model of 1.68 x 30 = 50.4 cm
Since each toothpick is 6.3 cm tall, the total number of toothpicks required for 50.4 cm = 50.4/6.3 = 8 toothpicks
If using cotton swabs each 7.6 cm tall, the number of cotton swabs would be 50.4/7.6 = 6.63
Rounding this to the nearest number means you will need 7 cotton swabs
