Answer:
x = 0.86
Step-by-step explanation:
(3x - 1)(x + 6) = 3.14159 × (x + 1)²
3x² + 17x - 6 = 3.14159 × (x² + 2x + 1)
-0.14159x² + 10.7168x - 9.14159 = 0
x² - 75.6875x + 64.5626 = 0
[tex] x = \dfrac{-(-75.6875) \pm \sqrt{(-75.6875)^2 - 4(1)(64.5626)}}{2(1)} [/tex]

Find the missing measurement using the given scale factor. B А scale factor from A to B = 1:7
Answer:
? = 49
Step-by-step explanation:
To solve this we just need to understand that when A=1, B=7. So when the side for a is 7 that is basically multiplying A by 7 so we have to do the same to the B side. So when the B side is multiplied by 7 it would be 7*7 =49 so the ? is equal to 49 when that similar side is equal to 7.
This is all based on the fact that the two triangles must be similar triangles.

Two large numbers of the Fibonacci sequence are F(49) = 7,778,742,049 and
F(50) = 12,586,269,025. If these two numbers are added together, what
number results?
O A. F(54)
O B. F(51)
O C. F(52)
D. F(99)
SUBMIT
F(51)
===========================================================
Explanation:
The very large numbers are likely put there as a distraction. They aren't needed. Adding any two adjacent Fibonacci numbers will lead to the next term in the sequence. This is simply based on how the special number sequence is defined or set up.
This means F(49)+F(50) = F(51) i.e. adding the 49th and 50th terms will generate the 51st term.
In general,
F(n) + F(n+1) = F(n+2)
where n is a positive integer.

What do you think Thomas Edison meant by the word perspiration? How do those words apply to what you've learned about businesses in this lesson?
1. Thomas Edison used "perspiration" to refer to the physical and mental efforts needed to achieve a meaningful purpose in any human endeavor.
2. As it applies to businesses, it is not enough to develop a business idea or plan, as the business person must be prepared to execute and carry the business idea or plan to fruition.
What does Thomas Edison's reference mean?
According to Thomas Edison, the superior intellect or creativity we associate with great minds comes from inspiration (the idea) and perspiration (hard work).
Perspiration literarily refers to the sweat that emanates as someone works hard.
Without a strong working ethic, it will be impossible to achieve great results from only the proposition of great ideas or business plans.

Cora works as a plumber and earns $50 per house call, plus $18 for every hour of work. She billed a customer $104, but forgot how long she worked. To solve for the number of hours, she subtracted 50 from 104 and then divided by 18.
Answer:
Cora worked 3 hours
Step-by-step explanation:
104 = 18x + 50 ( x = # of hours worked)
54 = 18x ( subtracted 50 from both sides)
3 = x ( divided both sides by 18)

Method 1
Find the area of the rectangle, 45 cm². Subtract the area of the cut-out triangle from the rectangle, 45 - 6 = 39 cm²
Method 2
Separate the ribbon into two triangles and a rectangle.
33 + 3 + 3 = 39 cm²
Step-by-step explanation:
Formulae
Area of a rectangle = width × lengthArea of a triangle = 1/2 × base × heightMethod 1
Area of the rectangle:
= 3 × 15
= 45 cm²
Area of the cut-out triangle:
= 1/2 × 3 × 4
= 6 cm²
Find the area of the rectangle, 45 cm². Subtract the area of the cut-out triangle from the rectangle, 45 - 6 = 39 cm²
Method 2
Area of the rectangle:
= 3 × (15 - 4)
= 3 × 11
= 33 cm²
Area of one triangle:
= 1/2 × (3 ÷ 2) × 4
= 3 cm²
Separate the ribbon into two triangles and a rectangle.
33 + 3 + 3 = 39 cm²
Albert has a rectangular print that is 1 foot in length and 8 inches in width. He wants to reduce the dimensions of the print proportionally so that the new print has a width of 3 inches. What should be the length of the new print?
Answer:
2.6 inches
Step-by-step explanation:
As shown in the title if length is x,
x * 1/x = 8/3 * x
8 * 1 = 3x
x = 8/3 in
= 2.6 in
The new length of the rectangular print will be 2.68 feet.
What is a rectangle?A rectangle is a geometrical figure in which opposite sides are equal.
The angle between any two consecutive sides will be 90 degrees.
Area of rectangle = length × width.
Perimeter of rectangle = 2( length + width).
Given a rectangular print with dimensions,
Length = 1 foot = 12 inches
Width = 8 inches.
Area = 12(8) = 96 square inches
Now,
The area of the new print should be the same
So,
96 = Length × 3
Length = 32 inches = 2.67 feet.
Hence "The new length of the rectangular print will be 2.68 feet".
