After converting all measurements to the same format (decimals), we can see that the shortest piece of wood Jimmy measured is 4.02 ft.
To find the shortest piece of wood, we first need to convert all the lengths to the same format, preferably in decimals for easier comparison. The lengths of the wood pieces given are 4.2 ft, 9/2 ft, 4.02 ft, and 4 2/9 ft.
Let's break it down:
4.2ft remains as it is. 9/2ft equals 4.5ft when converted to a decimal. 4.02ft remains as it is. 4 2/9ft equals approximately 4.22ft when the fraction is converted to a decimal.
So, we have pieces of wood that are 4.2 ft, 4.5 ft, 4.02 ft, and 4.22ft. Looking at these numbers, it is clear that the piece of wood that measures 4.02 ft is the shortest.

how do i write this inequality
You must be at least 42 inches tall to ride the bumper cars at an amusement park. Write an inequality that represents this situation. Let x represent the heights of people who are allowed to ride the bumper cars.
The inequality for the given condition is x ≥ 42 inches
Solution:
Given that, the condition is you must be at least 42 inches tall to ride the bumper cars at an amusement park.
We have to write an inequality that represents this situation.
Equations and inequalities are both mathematical sentences formed by relating two expressions to each other. In an equation, the two expressions are deemed equal which is shown by the symbol =
Where as in an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥
Let "x" represent the heights of people who are allowed to ride the bumper cars
Height of people who are allowed to ride the bumper cars should be at least 42 inches
Height of people ≥ 42 inches [ since at least condition holds even at 42 value also ]
x ≥ 42 inches
Hence, the inequality for the given condition is x ≥ 42 inches

Answer:
C) 8, 15, 16 is NOT Pythagorean TRIPLET.
Step-by-step explanation:
There numbers a, b and c are said to be a PYTHAGORAS TRIPLET if
[tex](a) ^2 + (b)^2 = (c) ^2[/tex]
Now, here in the given options:
A)5, 12, 13
[tex](5)^2 + (12)^2 = 25 + 144 = 169 = (13)^2\\\implies (5) ^2 + (12)^2 = (13) ^2[/tex]
Hence, 5, 12, 13 is a Pythagorean TRIPLET.
B)7, 24, 25
[tex](7)^2 + (24)^2 = 49 + 576= 625 = (25)^2\\\implies (7) ^2 + (24)^2 = (25) ^2[/tex]
Hence, 7, 24, 25 is a Pythagorean TRIPLET.
C)8, 15, 16
[tex](8)^2 + (15)^2 = 64 + 225= 289 \neq (16)^2 = 256\\\implies (8) ^2 + (15)^2 \neq (16) ^2[/tex]
Hence, 8, 15, 16 is NOT Pythagorean TRIPLET.
D)11, 60, 61
[tex](11)^2 + (60)^2 = 121 + 3600 = 3721 = (61)^2\\\implies (11) ^2 + (60)^2 = (61) ^2[/tex]
Hence, 11, 60, 61 is a Pythagorean TRIPLET.
E)12, 35, 37
[tex](12)^2 + (35)^2 = 144 + 1225 = 3721 = (37)^2\\\implies (12) ^2 + (35)^2 = (37) ^2[/tex]

Jordan can run a mile in 8.4 minutes. How long would it take to run 6.21 miles
Final answer:
To find how long it takes Jordan to run 6.21 miles, multiply the per-mile time (8.4 minutes) by the total miles (6.21), resulting in approximately 52.164 minutes.
Explanation:
To calculate how long it would take Jordan to run 6.21 miles based on the information that Jordan can run a mile in 8.4 minutes, we use the following steps:
Multiply the time it takes to run one mile by the total number of miles.Time for 1 mile = 8.4 minutes
Total distance = 6.21 miles
Total time = 8.4 minutes/mile × 6.21 miles
Total time = 52.164 minutes
Therefore, it would take Jordan approximately 52.164 minutes to run 6.21 miles. This straightforward multiplication provides a precise estimate, illustrating the application of the mile pace to calculate the overall running time for the specified distance.
find the area of the figure.
12 ft
18 ft
18 ft
36 ft
The area of the given figure is 864 square feet.
To find the area of the given figure, we can break it down into two rectangles and then sum their areas.
The figure consists of two rectangles with dimensions:
1. The first rectangle has a length of 36 ft and a width of 18 ft.
2. The second rectangle has a length of 12 ft and a width of 18 ft.
The area (A) of a rectangle is calculated using the formula: [tex]\(A = \text{length} \times \text{width}\).[/tex]
For the first rectangle:
[tex]\[ A_1 = 36 \, \text{ft} \times 18 \, \text{ft} = 648 \, \text{ft}^2 \][/tex]
For the second rectangle:
[tex]\[ A_2 = 12 \, \text{ft} \times 18 \, \text{ft} = 216 \, \text{ft}^2 \][/tex]
Now, add the areas of both rectangles to find the total area (A) of the figure:
[tex]\[ A = A_1 + A_2 = 648 \, \text{ft}^2 + 216 \, \text{ft}^2 = 864 \, \text{ft}^2 \][/tex]

6% of what number is 2.36
Answer:
39.3
Step-by-step explanation:
100 / 6 is about 16, 16.66667 to be exact:
2.36 * 16.66667 = approx. 39.3
Final answer:
To determine 6% of what number is 2.36, divide 2.36 by 0.06, resulting in an answer of approximately 39.33.
Explanation:
To find 6% of what number equals 2.36, we set up an equation where 6% (or 0.06) multiplied by a number 'x' equals 2.36. The equation looks like this: 0.06x = 2.36. To solve for 'x', you divide both sides of the equation by 0.06, which yields x = 2.36 ÷ 0.06. After calculating, you get that x equals 39.33. Therefore, 6% of 39.33 is 2.36.

In a triangle ABC, measure of angle B is 90 degrees. AB is 3x-2 units and BC is x+3. If the area of the triangle is 17 sq cm, form an equation in terms of x and solve it.
Answer:
[tex]x=\frac{8}{3}\ cm[/tex]
Step-by-step explanation:
we know that
The area of the right triangle ABC is equal to
[tex]A=\frac{1}{2}(AB)(BC)[/tex]
we have
[tex]A=17\ cm^2[/tex]
[tex]AB=(3x-2)\ cm[/tex]
[tex]BC=(x+3)\ cm[/tex]
substitute the values
[tex]17=\frac{1}{2}(3x-2)(x+3)[/tex]
[tex]34=(3x-2)(x+3)[/tex]
[tex]34=3x^2+9x-2x-6[/tex]
[tex]3x^2+7x-6-34=0[/tex]
[tex]3x^2+7x-40=0[/tex]
The formula to solve a quadratic equation of the form
[tex]ax^{2} +bx+c=0[/tex]
is equal to
[tex]x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}[/tex]
in this problem we have
[tex]3x^2+7x-40=0[/tex]
so
[tex]a=3\\b=7\\c=-40[/tex]
substitute in the formula
[tex]x=\frac{-7(+/-)\sqrt{7^{2}-4(3)(-40)}} {2(3)}[/tex]
[tex]x=\frac{-7(+/-)\sqrt{529}} {6}[/tex]
[tex]x=\frac{-7(+/-)23} {6}[/tex]
[tex]x=\frac{-7(+)23} {6}=\frac{16}{6}=\frac{8}{3}[/tex]
[tex]x=\frac{-7(-)23} {6}=-5[/tex]
therefore
The solution is
[tex]x=\frac{8}{3}\ cm[/tex]

Final answer:
To find the equation of the line passing through (0,2) and (5,8), we calculate the slope as 6/5 and use the y-intercept of 2 to write the equation as y = (6/5)x + 2.
Explanation:
To find an equation of the line that passes through the points (0,2) and (5,8), we need to calculate the slope and use one of the points to write the equation in the slope-intercept form y = mx + b, where m is the slope and b is the y-intercept.
First, let’s find the slope of the line using the formula m = (y2 - y1) / (x2 - x1). Substituting the given points, we get m = (8 - 2) / (5 - 0), which simplifies to m = 6 / 5. This is the slope of the line.
Now, we can use the slope and one of the points to find the y-intercept. Since the line passes through (0,2), we know that the y-intercept b is 2. Therefore, the equation of the line is y = (6/5)x + 2.

12. Find the two numbers. Use a comma to separate your answers.
Answer:
Two such numbers are 10 , 2 .
Step-by-step explanation:
Here, the question is INCOMPLETE.
Here is the Complete question:
One number is 1/5 of another number. The sum of the two numbers is 12. Find the two numbers. Use a comma to separate your answers.
We can solve the given problem as follows:
Here, : One number is 1/5 of another number.
Let one such number = m
⇒ The other number = 1/5 (m)
Sum of both the given number = 12
[tex]\implies m + \frac{1}{5} m = 12\\\implies \frac{5m + m}{5} = 12\\\implies \frac{6m}{5} = 12[/tex]
or, 6 m = 12 x (5) = 60
or, m = 60 / 6 = 10
or, m = 1 0
Hence, the first number = m = 10
Second number is [tex]\frac{1}{5} m = \frac{1}{5} \times 10 = 2[/tex]
Hence, two such numbers are 10 , 2 .
