Answer:

35.6 units

Step-by-step explanation:

By intersecting chords theorem:

10*x = 16*16

10x = 256

x = 256/10

x = 25.6

AB = 10 + x

AB = 10 + 25.6

AB = 35.6

a=72

Answer:

Hatim=37kg, Fatin=31

Step-by-step explanation:

Hatim=x, Fatin=x-x

x+x-6=68

add 6 to both sides

x+x=74

2x=74

divide both sides by 2

x=37

put in 37 fo the values determined earlier

Hatim=37, Fatin=37-6

Hatim=37, Fatin=31

check by plugging in the values

37+31=68 (or 37+37-6=68, either one works)

Answer:

A

Step-by-step explanation:

Flat fee is $20 [initial cost]

Each bucket of ball is $5.75

b is the number of buckets and c is the total cost

To get total cost, we add the flat fee with the bucket fee. Bucket fee is $5.75 multiplied by the number of buckets, which is b.

So, we have:

cost = $20 + $5.75b

In equation it is:    

Choice A is right.

Respuesta:

Los enteros positivos, o números enteros, se utilizan de muchas maneras durante la vida diaria. Los números de carretera se contabilizan junto con los límites de velocidad de la carretera. Los enteros se utilizan para comprender qué velocidad conducir en una carretera determinada. Los números en los relojes se utilizan para entender la hora y para configurar las alarmas del reloj. Hay números en edificios y casas para identificar direcciones y números para los niveles de piso dentro de los edificios. Los mapas utilizan enteros para proporcionar dirección e información. Los enteros negativos pueden ser menos obvios para su uso en la vida cotidiana. Algunos ejemplos de uso negativo de enteros incluyen las lecturas del termómetro, manteniendo la puntuación en un juego de hockey, altitud y bancos. Aunque todos estos ejemplos utilizan enteros positivos, también utilizan enteros negativos. Un termómetro utiliza negativo enteros para representar temperaturas por debajo de cero. En hockey, cuando el otro equipo anota en la línea del primer equipo, es un menos, pero cuando el primer equipo anota, es un plus. La altitud que está por debajo del nivel del mar está representada con números negativos. Los bancos y las cooperativas de crédito representan débitos con enteros negativos y créditos con enteros positivos.

Answer:

57 because 6 is 123 and so is 4 so 180 - 123 and you get 57.

Answer:

The measure of angle one is 57.

Step-by-step explanation:

The 2 angles are supplementary, which means that they add up to 180 degrees.

180-123=57

Step-by-step explanation:

The height of the scale model is 13.92 feet. (Rounding to the nearest hundredth).

Step-by-step explanation:

These are the measurements of the real building:

Height = 30 feet

Width = 30 feet

Length = 30 feet

Volume of the real building = 30 * 30 * 30 = 27,000 cubic feet

These are the measurements of the scale model:

Volume of the scale model = 10% of 27,000 cubic feet

Volume of the scale model = 0.1 * 27,000 = 2,700 cubic feet

Height = ∛ 2,700 = 13.92 feet (Rounding to nearest hundredth)

Width =  ∛ 2,700 = 13.92 feet (Rounding to nearest hundredth)

Length =∛ 2,700 = 13.92 feet (Rounding to nearest hundredth)

The height of the scale model is 13.92 feet.

Answer:

28,96 ft (round to the nearest hundreds)

Step-by-step explanation:

1) find the volume of the first cube

V = side^3 = 30^3 = 27000 ft^3

2) find the 10% of 27000

27000 / 0,1 = 2700

3) find the volume of the second cube

V = 27000- 2700 = 24300 ft^3

4) find the height

height = ∛24300 = 28,96 ft (round to the nearest hundreds)

The following examples have a unit rate of 30 meters per second:

B) 90 meters in 3 seconds.

D) 150 meters in 5 seconds.

The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.

Given:

We have the unit rate of 30 meters per second.

A) 90 meters in 5 seconds.

The unit rate = 90/5 meters per second.

The unit rate = 18 meters per second.

B) 90 meters in 3 seconds.

The unit rate = 30 meters per second.

C) 120 meters in 6 seconds.

The unit rate = 20 meters per second.

D) 150 meters in 5 seconds.

The unit rate = 30 meters per second.

E) 240 meters in 6 seconds.

The unit rate = 40 meters per second.

Therefore, B and D have the unit rate of 30 meter per second.

Answer:

it would be see explanation

Step-by-step explanation:

The n th term of a geometric sequence is

= a

where a is the first term and r the common ratio

Both a and r have to be found

Given a₃ = - 2, then

ar² = - 2 → (1)

Given a₇ = - 32, then

a = - 32 → (2)

Divide (2) by (1)

= , that is

= 16 ( take the fourth root of both sides )

r = 2 ← common ratio

Substitute r = 2 into (1)

a × 2² = - 2, that is

4a = - 2 ( divide both sides by 4 )

a = -  ← first term

. easy

Hence
