C = 2πr  or  C = πd

Diameter d = 57 cm

C = πd

C = π*57 = 57π

C ≈ 57 * 3.14159 = 179.07063

Exact circumference is  57π  cm  or

≈ 179.07 cm.

Matt, a 180 pound (82 kg) male, goes to a party and is served beer in a 16-ounce (473 ml) red plastic cup. he has 3 cups of beer
goblinko [34]

4 Standard drinks he has consumed in over a two - hour time period.

<h3>What is Unitary Method?</h3>

The unitary method is a method in which you find the value of a unit and then the value of a required number of units.

For example: 5 cars have price of $500. what will be the price of 10 cars.

Now, we know

5 cars → $500

1 car → $500/5

1 car → $100

10 cars → 8 x $100

10 cars → $800

The standard drink contains 12 - ounce of beer.

Here, we have given 1 red cup which has 16 - ounce of beer.

He has 3 red cups.

So, total ounce of beer he has consumed in two hour time period:

16 x 3 = 48 ounce of beer.

Now, as we know standard drink contains 12 - ounce of beer.

so, Number of standard drink = 48/12 = 4

Hence, 4 Standard drinks he has consumed in over a two - hour time period.

Polygon ABCD reflects about line to make polygon EFGH. What is the length of ? A. 2 units B. 2.2 units C. 3 units D. 3.2 units
Mademuasel [1]

Answer:

A) LEngth of FG is 2 units

Step-by-step explanation:

Considering the diagram attached below.

Reflection of any polygon does not affects its length.

As it is given both polygons are reflection of each other so their sides are congruent.

AB ≅ EF = 3 units

BC ≅ FG = 2 units

CD ≅ GH = 2.2 units

DA ≅ HE = 3.2 units

I need help with this please
arlik [135]
To find slope, pick any 2 points and use formula: (y2-y1)/(x2-x1)
2 points on line: (4,0), (0,-2)
(-2-0)/(0-4) = -2/-4 = 1/2
a) the slope is 1/2

Y = 1/2x + b
0 = 1/2(4) + b
0 = 2 + b, b = -2
b) -2 is the y intercept

Put the equation together
c) y = 1/2x - 2

In the equation, C = 8n + 25, C represents amount of money raised and n represents the number of pledges. How many pledges are n
DENIUS [597]

Answer:

103 pledges

Step-by-step explanation:

The equation we have here is;

C = 8n + 25

Now we need to find n given that c is $850

simply substitute for the value of c in the question

850 = 8n + 25

850-25 = 8n

825 = 8n

n = 825/8

n = 103.125

But since a pledge cannot be fractional, we can say that n = 103
