Write a fraction less than 1 with a denominator of 6 that is greater than 3/4
Marizza181 [45]
\frac{5}{6} is a fraction with the denominator 6. It is less than one (5/6 = 0.83 [rounded]. 0.83 is less than 1) but greater than \frac{3}{4} (3/4 = 0.75. 0.75 is less than 0.83)

Note: To turn a fraction into a decimal you simply divide the numerator by denominator. (\frac{numerator}{denominator} → numerator/denominator → (decimal)

¿Cuál es el volumen de una lata de chícharos que tiene un diámetro de 6 cm<br>y una altura de 8 cm?​
ivanzaharov [21]

Answer:

La respuesta podría ser 226.08 o 72π, dependiendo de si quieren que redondees pi o que solo pongas el símbolo.

Step-by-step explanation:

Para hallar el volumen de un cilindro, hay que primero hallar el área del círculo que tiene, por así decirlo. Entonces sería el radio al cuadrado, o sea 3 por 3 porque el diámetro es 6. Y luego lo multiplicamos por pi, y vendría siendo 9π o 9(3.14). Después, lo multiplicamos por la altura, 8 cm. Lo que nos daría 72π, o 226.08 ya redondeado.

Two toy rockets are launched straight up into the air. The height, in feet, of each rocket at t seconds after launch is given by
Tema [17]

Given:

The height, in feet, of each rocket at t seconds after launch is given by the polynomial equations:

Rocket A: -15t^2+100t

Rocket B: -14t^2+85t+3

To find:

The equation to find the "difference" in height of Rocket A and Rocket B.

Solution:

The difference in height of Rocket A and Rocket B is:

Difference = Height of Rocket A - Height of Rocket B

\text{Difference}=(-15t^2+100t)-(-14t^2+85t+3)

\text{Difference}=-15t^2+100t+14t^2-85t-3

\text{Difference}=(-15t^2+14t^2)+(100t-85t)-3

\text{Difference}=-t^2+15t-3

Therefore, the difference in height of Rocket A and Rocket B is -t^2+15t-3.
