In Circle O, AD And BE Are Diameters. The Measure Of Arc AB Is 55 And Themeasure Of Arc CD Is 25.What

Answers

Answer 1
100. the diameter means the other half, so arc AD is 180 on both sides. so that means we can do 180-(25+55), which equals 100
Answer 2

Answer:

Arc AB = 55°

Angle AOB = 55° ( Centre angle is equal to respective arc )

Arc CD = 25°

Angle COD = 25° ( Centre angle is equal to respective arc )

Angle AOB + Angle BOC + Angle COD = 180° ( AD is the diameter)

55° + Angle BOC + 25° = 180°

Angle BOC + 80° = 180°

Angle BOC = 100°

This rectangle has a perimeter of 36 units. Create a table that shows the length and width with at least 3 different rectangles that also have a Create a table that shows the length and width with at least 3 different rectangles that also have a perimeters of 36 units. Describe the relationship between the columns of your table.

Answers

For the rectangle to have a perimeter of 36 units, the sum of the length and the width must equal 18 units

How to create the table?

The given parameter is:

Perimeter = 36 units

The perimeter of a rectangle is:

Perimeter = 2 * (Length + Width)

So, we have;

36 = 2 * (Length + Width)

Divide both sides by 2

Length + Width = 18

This means that for the rectangle to have a perimeter of 36 units, the sum of the length and the width must equal 18 units

So, the possible table of values is:

Length  Width

Some loose change (pennies, nickels, dimes, and quarters) found behind the couch. Brianna noticed more than half the coins were pennies. Geofrey noticed that there was at least one coin of each type. Michele noticed that you could not make change for the same amount using fewer coins. In the space below, write the total amount of change, in cents, that was found.

Answers

The total amount of change, in cents, that was found is determined as 96 cents.

Total amount of change

The total amount of change is calculated as follows;

let the total = T

there was at least one coin of each type

T = p + n + d + q

more than half of the coins were pennies

[tex]\frac{p+n + d + q }{2} \leq p[/tex]

Value of the coinspennies = $0.01nickels = $0.05dimes = $0.1quarters = $0.25

more than half = pennies

next, we have; nickels + dimes + quarters

number of dimes

y(dimes) = $0.25

y(0.1) = 0.25

y = 0.25/0.1

y = 2.5 ≅ 3

dimes = 3 coins

number of nickels

since dimes = 3 coins, number of nickels is now calculated as;

x(0.05) = 3(0.1)

x = (0.3)/(0.05)

x = 6 coins

nickels = 6 coins

Total coins

Total coins = nickels + dimes + quarters + pennies

pennies must greater than 6 coins, since we can't have fewer coins.

Total coins = nickels + dimes + quarters + pennies

let pennies = 7

Total coins = 6 + 3 + 1 + 7

Total coins = 17

half of 17 = 8.5

7 is less than half (8.5), number of pennies cannot be 7, since more than half of the coins are pennies.

let pennies = 11

Total coins = 6 + 3 + 1 + 11

Total coins = 21

half = 10.5

11 is more than half (10.5)

more than half = number of pennies = 11

Total amount in cents

11($0.01) + 6($0.05) + 3($0.1) + 1($0.25) = $0.96 = 96 cents

The base diameter and the height of a cone are both
equal to x units.

Answers

Answer:

π x³ /12 is the volume of the cone if  A cone has a height of x and a diameter of x

Step-by-step explanation:

The base diameter and the height of a cone are both equal to x units

Diameter of cone = x  units

Radius = Diameter /2

=> Radius of cone = x/2 units

Height of cone =x units

Volume of cone = (1/3) π r²h

r = radius h = height

=> Volume of cone =  (1/3)π (x/2)² * x

= (1/3) π (x²/4) * x

= (1/12)  π x³

= π x³ /12 cubic units
