How you can solve this answer put. 11x+11+110=180 first you subtract 110-180=70-11=59÷11 which turns into a decimal you have to find decimal though good luck

Arjun is twice as old as Shreya. If five years ago his age was three times Shreya's age, then Arjun's present age is

drek231 [11]

Answer:

Arjun is 20 years old and Shreya is 10 years old.

Step-by-step explanation:

5 YEARS AGO-

Arjun: 2x-5

Shreya: x-5

NOW-

Arjun: 2x

Shreya: x

EQUATION-

2x-5=3(x-5) = 2x-5=3x-15

(add 15 on both sides)

2x+10=3x

(subract 2x from both sides)

x=10

Therefore, Arjun is 20 years old and Shreya is 10 years old :)

Surface area is the sum of the areas of each side of a three dimensional object.

There are two sides that are 11x9, two sides that are 9x3, and two sides that are 11x3.

So the surface area is:

2(11)(8)+2(9)(3)+2(11)(3) = 296 ft^2

A supplier of heavy construction equipment has found that new customers are normally obtained through customer requests for a sa

ziro4ka [17]

Answer:

The probability that it will take fewer than six customer contacts to clear the inventory is 0.8%.

Step-by-step explanation:

We have a probability of making an individual sale of p=0.15.

We have 4 units, so the probability of clearing the inventory with n clients can be calculated as:

$P=\dbinom{n}{4}p^4q^{n-4}=\dbinom{n}{4}0.15^4\cdot 0.85^{n-4}$

As we see in the equation, n has to be equal or big than 4.

In this problem we have to calculate the probability that less than 6 clients are needed to sell the 4 units.

This probability can be calculated adding the probability from n=4 to n=6:

$P=\sum_{n=4}^6P(n)=\sum_{n=4}^6 \dbinom{n}{4}0.15^4^\cdot 0.85^{n-4}\\\\\\P=0.15^4(\dfrac{4!}{4!0!}\cdot 0.85^{4-4}+\dfrac{5!}{4!1!}\cdot0.85^{5-4}+\dfrac{6!}{4!2!}0.85^{6-4})\\\\\\P=0.15^4(1\cdot0.85^0+5\cdot0.85^1+15\cdot0.85^2)\\\\\\P=0.00051(1+4.25+10.84)\\\\\\P=0.00051\cdot16.09\\\\\\P=0.008$
