A population of llamas stranded on a desert island is decreasing due to a food shortage by 6% per year. If the population of llamas started out at 350, how many are left on the island 10 years later?

Answers

Answer:

189

Step-by-step explanation:

Given data

Initial population=350

Rate = 6%

TIme= 10 years

Let us apply the compounding expression

A=P(1-r)^t----------The negative sign is due to decreasing value

substitute

A= 350(1-0.06)^10

A=350(0.94)^10

A=350*0.5386

A=188.51

Hence the approximate population will be 189

SE TIENE 45 NIÑOS Y 35 NIÑAS. DE LOS CUALES 60 VIVEN EN EL DISTRITO DE BREÑA. SI EL 30% QUE NO VIVEN EN BREÑA SON MUJERES. ¿QUÉ CANTIDAD SON VARONES?

Answers

Answer:

14 son varones

Step-by-step explanation:

Primero tenemos que sumar la cantidad de niños y niñas para saber cuantos hay en total

45 + 35 = 80

60 de ellos viven en el Distrito de Breña entonces los descontamos del total

80 - 60 = 20

Esto nos dice que 20 NO viven en Breña. Si 30% son mujeres quiere decir que el resto 70% son varones. Asi que multiplicamos los 20 por 70% en formato decimal que seria 0.70

20 * 0.70 = 14

Finalmente, podemos ver que 14 son varones viviendo fuera de Breña

What interval consists of all $u$ such that neither $2u$ nor $-20u$ is in the interval $(-\infty,-1)$ ?

Answers

Answer:

[-1/2,1/20]

Step-by-step explanation:

Answer:

[-1/2,1/20]

Step-by-step explanation:

In terms of inequalities, we are asked to find all $u$ such that $2u\ge -1$ and $-20u\ge -1$.

The solution to the first inequality, obtained by dividing both sides by $2$, is $u\ge -\frac{1}{2}$.

We can solve the second inequality by dividing both sides by $-20$, but because we are dividing by a negative number, we must reverse the direction of the inequality: $u\le \frac{1}{20}$.

The set of $u$ which satisfy both inequalities simultaneously is thus $\boxed{\left[-\frac{1}{2},\frac{1}{20}\right]}$.

A hot air balloon went from an elevation of 5,717 feet to an elevation of 3,388
feet in 34 minutes. What was its rate of descent?
The rate of the descent was
feet per minute.

Answers

Answer:

68.5 feet per minute

Step-by-step explanation:

rate of descent = feet / minute

First you need to find how many feet it has descended:

beginning altitude- ending altitude = total feet descended

5717 feet - 3388 feet = 2329 feet

To figure out the rate of decent we will divide

2329 feet / 34 minutes = 68.5 feet per minute

The hot air ballon descended 68.5 feet per minute for 34 minutes.

143 inches = ________ a) 14 feet 3 inches b) 13 feet 9 inches c) 12 feet 2 inches d) 11 feet 11 inches

Answers

Answer:

D. 11 feet 11 inches

1 foot= 12 inches

143/ 12 = 11 11/12

Answer:

D) 11 feet and 11 inches

Step-by-step explanation:

First we know that there is 12 inches in a foot. So let's start with a.

14 inches x 12 inches (one foot) is 168 inches (so it's not this one:)

13 inches x 12 inches is 156 inches (It's not this one either)

12 inches x 12 inches is 144 inches (not this one)

11 inches x 12 inches is 132 inches (so it could be this one, let's add the remaining inches).

132 + 11 inches = 143 inches.

(Notice I didn't add the remaining inches on A, B, or C because the number of inches was already too much. I did on D because the number of inches was below the given number of 143.
