Answer:

176.63 cubic in. =A

Step-by-step explanation:

The area of a circle can be found by using the equation \pi r^{2}=A. The problem gives us the diameter, but we need the radius. To find the radius divide the diameter by 2, so raduis= 7.5 in.

\pi r^{2}=A

(3.14)(7.5^{2})=A

(3.14)(56.25)=A

176.63 cubic in. =A

Which procedure justifies whether Negative 3 x (5 minus 4) + 3 (x minus 6) is equivalent to Negative 12 x minus 6? The expressio
Nady [450]

Answer:

The expressions are not equivalent because -3(2)(5-4)+3(2-6)=-18 and -12(2)-6=-30

Step-by-step explanation:

Two expressions are said to be equal if after a number is substituted to the expression, they produce the same result (that is they have the same value).

To determine whether -3x(5-4)+3(x-6) is equivalent to -12x-6, we have to substitute the same number to the expression and see if it produces the same result.

Substituting 2 to the first expression gives:

-3×2(5-4) + 3(2 - 6) = -6 - 12 = -18

Substituting 2 to the second expression gives:

-12(2) - 6 = -24 - 6 = -30

Since -3×2(5-4) + 3(2 - 6) = -6 - 12 = -18 and -12(2) - 6 = -24 - 6 = -30, the expressions are not equivalent because they do not produce the same result.

Can someone help me with 4-6 plz
satela [25.4K]

Step-by-step explanation:

4. To use SSS, you need three pairs of congruent sides.  You're given two pairs of congruent sides, so the additional information needed is WY ≅ KM.

5. To use ASA, you need a pair of congruent sides between two pairs of congruent angles.  You're given one pair of congruent angles, and since the triangles share a common side, we know BC ≅ BC.  So the additional information needed is ∠WBC ≅ ∠ACB.

6. To use SAS, you need a pair of congruent angles between two pairs of congruent sides.  You're given two pairs of congruent sides, so the additional information needed is ∠I ≅ ∠F.

suter [353]

Answer:

Step-by-step explanation:

Given that customers arrat a service window according to a poisson process with an average of 0.2 per minute

=  12 per hour.

a)  the probability that the time between two successive arrivals is less than 6 minutes

= For one hour more than 60/6 =10 customers arrive.

P(X>10) = 0.6528

b) Prob that there will be exactly three arrivals during a given 10-minute period

P(x=3) for average 2

= 0.1804
