Answer:

x = 27/10 or x = 2.7

Step-by-step explanation:

Step 1: Get rid of the denominator.

LCD of 4 & 3: 12

Multiply both sides by 12.

12 ( 2x - 1 / 4 ) + 12 ( x / 3 ) = 12 (2)

Reduce the numbers.

3 ( 2x - 1) + 4x = 24

Step 2: Distribute.

6x - 3 + 4x = 24

Step 3: Collect like terms.

6x + 4x = 24 + 3 ( - 3, the sign change when moved to the other side)

10x = 27

Step 4: Solve for x.

Multiply both sides by 10.

10x / 10 = 27 / 10 (the 10 cancels out)

x = 27 / 10 or x = 2.7

Answer: x = 27 / 10 or x = 2.7

Mandy has an IQ of 115. We know that the mean () IQ is 100 with a standard deviation of 15. There are 100 people in Mandy’s Alc
Alex787 [66]

Answer: 16

Step-by-step explanation:

Given : Mean : \mu=100

Standard deviation : \sigma =15

The value of z-score is given by :-

z=\dfrac{x-\mu}{\sigma}

For x= 115

z=\dfrac{115-100}{15}=1

The p-value : P(z>1)=1-P(z

Now, the number of people smarter than Many is given by :_

100\times0.1586553=15.86553\approx16

Hence, there are 16 members smarter than Mandy.

Answer:

1/3*9.7*Pi*7.6^2 ft^3 and then round to nearest tenth

Step-by-step explanation:

The trick is knowing that the volume of the cone is exactly 1/3 of the volume of the cylinder with the same radius & height. This relation can be derived using integrals.

7) c/a=d-r, for a<br><br> thanks
elena-14-01-66 [18.8K]

Answer:

a = c/(d - r)

Step-by-step explanation:

Multiply both sides by a

(c/a)a = (d - r)*a  Notice how this is written. You need to introduce brackets on the right because both d and r are multiplied by a.

c = (d - r)*a                

Divide both sides by (d - r)

c/(d - r) = a*(d - r)/(d - r)

c/(d - r) = a
