Answer:
18
Step-by-step explanation:
There is a string that is 3 yards long that is divided into pieces that are 1/6 of yard long. Divide the total length by the length it was divided into to find the number of pieces.
When dividing with fractions, the second number will be inverted and multiplied by the first number.
3 ÷ (1/6) = 3 × 6 = 18
You will have 18 pieces

Step-by-step explanation:
Answer:
The length of the remaining wire is 53.8 centimeters
Step-by-step explanation:
Let us solve the question
∵ Cory has 66.92 centimeters of wire
∵ He uses 2 pieces of the wire, each piece he uses is 6.58 cm long
→ Find the length of the two pieces he uses
∵ He uses = 2 × 6.58
∴ He uses = 13.16 cm
∴ The length of wire he uses is 13.16 cm
→ The length of the remaining = the total length - the length he uses
∵ The length of the remaining = 66.92 - 13.16
∴ The length of the remaining = 53.76 cm
→ Round it to the nearest tenth of a centimeter
∴ The length of the remaining = 53.8 centimeters
∴ The length of the remaining wire is 53.8 centimeters
10 1/3= 31/3
31/3= 93/9
11 5/9= 104/9
93/9 + 104/9 = 197/9
197/9= 21 8/9
your answer is 21 & 8/9

Answer:
<h2>The discriminant is is 144</h2>
Step-by-step explanation:
Step one
Given the expression
![f(x) = 2x^2- 8x - 10.](https://tex.z-dn.net/?f=f%28x%29%20%3D%202x%5E2-%208x%20-%2010.)
we can solve for the The discriminant using the expression
![b^2 - 4ac](https://tex.z-dn.net/?f=b%5E2%20-%204ac)
Step two
from the given expression
the second term b=-8
the first term a= 2 and
the constant term c=-10
Step three
substituting all the terms into the expression
we have
![b^2 - 4ac = (-8)^2 - (4)(2)(-10) =64- (-80)= 64+80= 144](https://tex.z-dn.net/?f=b%5E2%20-%204ac%20%3D%20%20%28-8%29%5E2%20-%20%284%29%282%29%28-10%29%20%3D64-%20%28-80%29%3D%2064%2B80%3D%20144)
