The 3-4-5 rule is a rule that states that in any right triangle, the ratio of the length of the two shorter sides will be 3:4 if the length of the hypotenuse is 5.
To determine if a triangle is a 3-4-5 triangle, you can use the following steps:
Identify the hypotenuse (the longest side of the triangle)Divide the length of the hypotenuse by 5.Multiply the result by 4 to find the length of the side opposite to the right angle.Multiply the result by 3 to find the length of the side adjacent to the right angle.For example, if the hypotenuse of a triangle is 10 units, you can use the 3-4-5 rule to determine if it is a 3-4-5 triangle:Divide the length of the hypotenuse by 5: 10 / 5 = 2
Multiply the result by 4: 2 x 4 = 8
Multiply the result by 3: 2 x 3 = 6
So, the triangle has sides of 6, 8, and 10 units, which is a multiple of 3-4-5 triangle and it is a right triangle.
Note that not all triangles that have sides in the ratio 3:4:5 will be a right triangle, only those that have a 90-degree angle are considered as a right triangle.

What is 3/8 simplified and divided please show steps
Answer:
0.375
cannot be simplified more.
Step-by-step explanation:
three is prime, meaning it can only be divided by 1 and itself. When you see a prime in a fraction, you cannot simplify anymore without accidentally making it more complicated. Divided would just be the decimal form. The decimal form of 1/8 is 0.125, so if you multiply it by three you should get 3/8=0.375
4. Sarah, Toby, and their mother run an online store called Unique Bracelets that sells handmade bracelets consisting of unique, individually-painted charms. Each bracelet they sell consists of 12 small charms and 5 large charms. Each order also gets 5 blank spacer charms to use to separate charms or fill in the bracelet. They do not sell charms separately and do not sell bracelets in parts. (f) Write an equation showing the number of charms, y, needed for x bracelets purchased in an order. Describe what the equation means in a real-world context.
Complete question :
Sarah, Toby, and their mother run an online store called Unique Bracelets that sells handmade bracelets consisting of unique, individually painted charms. Each bracelet they sell consists of 12 small charms and 5 large charms. Each order also gets 5 blank spacer charms to use to separate charms or fill in the bracelet. They do not sell charms separately and do not sell bracelets in parts.
(a) Write an equation showing the number of charms, y, needed for x bracelets purchased in an order. Describe what the equation means in a real-world context.
(b) Sarah’s and Toby’s mother says the order she is filling needs 158 charms. How many bracelets were purchased in this order?
(c) Toby says they don’t have enough charms to fill an order that needs 264 charms. Sarah says it’s notpossible for an order to need 264 charms. Is Sarah right? Why or why not? Justify your answer.
Answer:
y = 17x + 5 ;
9 bracelets ;
Sarah is right
Step-by-step explanation:
Contents per bracelet :
Small charms per bracelet = 12
Large charms per bracelet = 5
Blank spacer charms per order = 5
Number charms, y needed for X bracelets in an order ;
1 order ; x bracelets
12 + 5 = 17 small and large charms
5 = black spacer charms per order
y = 17x + 5
B.)
Order requiring 158 charms, number of bracelets :
y = 158
158 = 17x + 5
158 - 5 = 17x
153 = 17x
x = 153 / 17
x = 9 bracelets
Order requiring 264 charms
y = 264
264 = 17x + 5
264 - 5 = 17x
259 = 17x
x = 259 / 17
x = 15.23 bracelets
Sarah is right, the number of bracelets should be a positive integer and not a decimal.

The area of the triangle above will equal one half of a rectangle that is 5 units long and __ units wide. (Input only whole numbers, such as 8.)
Answer:
2
Step-by-step explanation:
Find the diagram attached
The Base of the triangle will be equivalent to the the length of the rectangle
Since the base of the triangle is 5units, hence length of the rectangle is 5units
Similarly, the height of the triangle is corresponding to the width of the rectangle
Since the height of the triangle is 2 units, the rectangle will be 2 unts wide. Hence the required answer is 2units

[tex]18 = -5b - 17[/tex]
Answer:
b = -7
Step-by-step explanation:
18 = -5b-17
Add 17 to each side
18+17 = -5b-17+17
35 = -5b
Divide each side by -5
35/-5 = -5b/-5
-7 = b

At her most recent race, Sue finished in 272 minutes. That is 15% less time than the previous race. What was her time in the previous race?
Answer:
320 minutes was her time on the previous race
Step-by-step explanation:
Let the time spent on the previous race be x minutes.
Given that at her most recent race, Sue finished in 272 minutes which is 15% less time than the previous race then
x - 15% * x = 272
x - 0.15x = 272
0.85x = 272
x = 272/0.85
x = 320 minutes

what is the density of a pine log if the weight is 42.63 lbs, radius 5 in, length 30in
Answer:
Step-by-step explanation:
density is weight divided by volume. And the volume of a log is like a cylinder.
V=hpi(r^2) in this case
V=25(30)pi=750pi so
d=(42.63)/(750pi)
d=0.018 lb/in^3

Answer:
[tex]\frac{-1}{7}[/tex] or 0.14
Step-by-step explanation:
To find slope you can use the formula
mx=[tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
or
[tex]\frac{rise}{run}[/tex]
Rise over run:
Rise over run is the easiest of the two so we'll be using that one first for this question, but both should give you the same answer
To find rise over run, select the points and see how many points up or down you must got to make it the same level as the other point
In this case, the point (-3,1) would have a run of -1 because you have to move down one
To find run, now that you have rise start from that point and count how far you have to go to get to the next point. You should be going in a straight line.
The run would be 7.
Now you make it a fraction/division problem
[tex]\frac{rise}{run} =\frac{-1}{7}[/tex]
-0.14285714285714285714285714285714 <- decimal value
-0.14
Depending on what it means by reduce, your answer will either be -1/7 or the decimal. Use the reduced decimal value if it's asking for a decimal
I've included a picture in case my explanation was not satisfactory or you need a visual.
Slope form:
Identify the two points
First one will be (-3,1)
Second one would be (4,0)
Now label them
-3 will be x1
1 is y1
4 is x2
0 is y2
You will be using [tex]\frac{y2-y1}{x2-x1}[/tex]
Put the values into the equation
[tex]\frac{0-1}{4--3} =\frac{0-1}{4+3} =\frac{-1}{7}[/tex]
You get the same thing as the previous way.
Same answer
Visuals also included

Answer:
10. 264
11. 13
Step-by-step explanation:
10- When we are doing perimeter we add all the sides together. Since it's a square this time, we know all the sides are even at 66ft.
66+66+66+66= 264
I added 4 times for each side we have and we get the perimeter of 264
11- When dealing with area, all we need is two numbers. To get area we multiply the length and width. If we have the area and want either length or width, we can still easily do that. All we have to do is divide the area from your given number.
65 divided by 5 is 13
Area divided by Length is Width
Answer:
#10= 264
#11= 13
Step-by-step explanation:
#10: We can see that this is a square because it says so in the question so we can assume that if it is a square then all the lengths and widths are 66 feet. 4(66) = 264 or 66+66+66+66 = 264
#11: 65/5 = 13 because it is dealing with area, simply just divide the total of area by the known length to get the width.
Find the measure of an angle and its complement if one angle measures 18 degrees more than the other?
Answer:
x+18=90-x
use this equation and solve
2x=72
x=36
36+18=54
90-54=36
54 degrees and 36 degrees
The solution is, the measure of an angle and its complement are, 54 degrees and 36 degrees.
What is an angle?In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.
We know that, a ray is a line that continues on forever inn one direction with a point at it's start.
here, we have,
let, one angle = x
x+18=90-x
use this equation and solve
2x=72
x=36
so, we get,
36+18=54
90-54=36
Hence, The solution is, the measure of an angle and its complement are, 54 degrees and 36 degrees.

A company has recently been hiring new employees. Today the company has 35% more employees than it did a year ago. If there are currently
43,200 employees, how many employees did the company have a year ago?
Answer:
28,080
Step-by-step explanation:
Turn 35% into a decimal (.35)Multiply .35 by the amount of current employees (.35 * 43200 = 15120)Subtract the current amount of employees (43200) by 15120 (the amount of employees that joined) which should be 28080.
