circumference/perimeter = 2 x pi x r or pi x d
so 2 x 3.14 x 1.7 = 10.676
so C (10.7)

Answer:

2πr=c, Perimeter, or Circumference is what we are looking for, and this is the formula.

so we need to figure out 2 x 3.14 x radius:1.7 = Perimeter or Circumference

2 x 3.14 = 6.28

6.28 x 1.7 = 10.28

P.S. answer is 10.7, my answer is simplified.

A triangle has side lengths of (6v+2) centimeters, (6v+5) centimeters, and (3w-2) centimeters. Which expression represents the perimeter, in centimeters, of the triangle?

ILL GIVE YOU BRAINS :)

Answers

The expression that represents the perimeter is [tex]12v + 3w + 5[/tex]

Definition of Perimeter

The perimeter of a figure is defined as the total length of the outer boundary of that figure. It is the sum of length of each side of a figure.

Calculation of Perimeter of given triangle:

Given,

The triangle has sides of length [tex](6v+2)cm, (6v+5)cm[/tex] and [tex](3w-2) cm[/tex].

The perimeter can be calculated by adding the sides.

⇒ [tex](6v+2) + (6v+5) + (3w-2)[/tex]

Now, like terms and constants can be written together

⇒ [tex]6v + 6v + 3w + 2 + 5 - 2[/tex]

⇒ [tex]12v + 3w + 5[/tex]

Hence, the expression that represents the perimeter of given triangle is [tex]12v + 3w + 5[/tex].

$679.80

B.
$615.25

C.
$690.00

D.
$650.50

Answers

The answer would be A)$679.80
The reason for this is let’s start with the mark up of 10%. Meaning we will add the result of the markup to our first number We would take 1000*.1 which would give us 100.
Add that to the original to give you $1,100.
Then the item was discounted for 40% meaning we take away the result of 1,100*.4 which equals 440. 1100-440=660.
Then taxes are added on to the total so you would do 660*.03 which would give you 19.8
660+19.8 gives you$679.80.

the answer is A i hope this helped

It takes 4.12 gallons of paint to paint a fence.

How much paint is needed for 1/5 of the fence?

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.

We are given that;

Paint= 4.12gallons

Now,

To find the amount of paint needed for 1/5 of the fence, we can use the following proportion:

14.12=1/5x

where x is the unknown amount of paint. To solve for x, we can cross-multiply and get:

x=14.12×1/5

Simplifying, we get:

x=0.824

Therefore, by unitary method the answer will be 0.824 gallons.
