Answer:
BC ≈ 20.9
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
BC² + AC² = AB²
BC² + 7² = 22²
BC² + 49 = 484 ( subtract 49 from both sides )
BC² = 435 ( take the square root of both sides )
BC = [tex]\sqrt{435}[/tex] ≈ 20.9 ( to the nearest tenth )

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
= - ← explicit formula
and
= - × = - 0.5 × 512 = - 256

¿En què situaciones usamos los nùmeros enteros positivos y negativos, escribe 2 ejemplos de cada uno? Por favor para ahora hocino me jalan :(
Answers
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.

A building in the shape of a cube has a width of 30 ft., a length of 30 ft., and a height of 30 ft. An architect wants to build a scale model of the building that is 10% smaller in volume. What is the height of the new building?
Answers
Answer:
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)
