You could simplify this expression, because there are multiple terms with the same variable.

8+7y+2x+4y+4
2x+7y+4y+4+8
2x+11y+12

2x+11y+12 is an equivalent expression to 8+7y+2x+4y+4

Hope this helped!

Orange traffic cones come in a variety of sizes. Approximate the volume, in cubic inches, of a traffic cone that has a height of

Irina18 [472]

Answer:

Volume of the cone = 628 cubic inches.

Step-by-step explanation:

Given:

Height of the traffic cone, $h$ = 2 feet = 24 inches ...[1 feet =12 inches]

Diameter of the cone, $d$ = 10 inches

Radius of the cone, $r$ = 5 inches ...[ $r=\frac{d}{2}$ ]

Value of pie, $\pi$ = 3.14

We have to find the approximate volume.

Lets say that the volume is $V$ .

Formula:

Volume of a cone = $\frac{\pi r^2h}{3}$

So,

⇒ $V=\frac{\pi r^2h}{3}$

⇒ Plugging the values.

⇒ $V=\frac{3.14\times 5^2\times 24}{3}$

⇒ $V=\frac{3.14\times 25\times 24}{3}$

⇒ $V=628$ $inches^3$

The volume of the orange traffic cone is 628 inches^3.

n a call center the number of received calls in a day can be modeledby a Poisson random variable. We know that, on average, 0.5%

guapka [62]

Answer:Pois(ln(200))

Step-byy-step explanation:

Let N be the number of received calls in a day

That is

N∼Pois(λ).

0.5% = 0.5/100 = 1/200 of no calls

P(N=0)=e^−λ=1/200

-λ=e^(1/200)

λ=in(200)

Our number of calls in a day is distributed Pois(ln(200)).

Angle 3 and Angle 6 are alternate interior angles. If angle 3 is (3x-5) degrees and angle 6 is (5x-25), what is the value of x?

Nataly [62]

Answer:

x = 10

Step-by-step explanation:

<u>Alternate interior angles measure same as per their property:</u>

m∠3 = m∠6
3x - 5 = 5x - 25
5x - 3x = 25 - 5
2x = 20
x = 10

How many numbers between 1 and 100 are multiples of both 2 and 7

liraira [26]

7. The formula is : $98-14=84$ and then $\frac{84}{14}$ and then $6+1=7$ .

The reason behind it is 14 is the least common multiple of 7 and 2 and 98 is the largest 2 digit multiple of 14. Subtract 98 and 14 and then divide by 14 to get 6 and then add 1. You will get 7 which is our answer!
