expand and simplify 2(3a-5b +4 (a+2b)

Answers

Answer 1

Answer:

14a + 6b

Step-by-step explanation:

To expand use distributive property. a*(b +c) =a*b +a *c

Simplifying an expression

2*(3a - 5b + 4*(a+2b) = 2*(3a -5b + 4*a +4*2b)

                                  = 2*(3a - 5b + 4a + 8b)

                                  = 2* (3a + 4a - 5b + 8b)

Combine like terms.  To combine like terms, add or subtract the coefficient of the variables. 3a and 4a   & (-5b) and 8b are like terms  

                                 = 2*( 7a + 3b)  

                                 = 2*7a + 2*3b

                                 = 14a + 6b

Answer 2

Hey there!


2(3a - 5b) + 4(a + 2b)

= 2(3a - 5b) + 4(1a + 2b)

= 2(3a) + 2(-5b) + 4(1a) + 4(2b)

= 6a - 10b + 4a + 8b

= (6a + 4a) - (10b + 8b)

= 6a + 4a - 10b + 8b

= 10a - 2b


Therefore, your answer is: 10a - 2b


Good luck on your assignment & enjoy your day!

what is 30x120? since i dont know how to multiply by doubles :)

Answers

Answer:

The answer to 30*120 is 3,600

Answer:

30 times 120 equals 3600

Step-by-step explanation:

One thing that is really easy to use to multiply is a calculator (either online or a hand-held one). But here is how you can multiply without a calculator...

Set up an equation on a piece of paper like how it is shown right below...

  30

x 120

Then, times the last digit (so the zero) of the bottom number. (But it doesn't really matter what order you put them in). Then, times it by the last digit of the top number. So that would equal 0! So as shown below, you would put the answer like so...

  30

x 120

      0

Then, you do 0 (last digit of bottom number) times 3 (you keep going left of the top number's digits). So that would also equal 0.

   30

x 120

   00

     0

Then you add a zero below, since we are now moving on to the next number to the left of the last digit of the bottom number (hopefully this is making sense). Then you do the exact same thing.

   30

x 120

   00

 600

Now that we're done with that, we add two zeros this time, since we are in the hundreds now. So it is to the next number now! (1) And then we do the exact same thing again!

   30

x 120

   00

 600

3000

Alright, that's done! Now we add all those answers together (0+600+3000)

And that gives us our answer! 3600!

Hopefully that made sense! :)

Let's say that the line crossing the middle of quadrant four was on the y-axis, that would be known as a 90 degree angle.  Since it was cut in half, that would become a 45 degree angle.

When measuring an angle rotate counter clockwise starting in Quadrant 1. (see picture)

Every axis you hit is 90 degrees.

Write an explicit formula for the arithmetic sequence:
-2,7,16,25,...

Answers

Answer:

a_n = 9n - 11

Step-by-step explanation:

Explicit rule for an arithmetic sequence is a_n = a_1 + (n-1) d

a_1 is the first term of the sequence

d is the common difference. To find d you pick a number in the sequence and subtract it by the previous number. For example, 7 - (-2) = 9

16 - 7 = 9 so, d = 9

a_1 = -2 since it is the first term. Now substitute these numbers into the formula.
a_n = -2 + (n-1)(9)

And then we simplify.
9 • n = 9n

9 • -1 = -9
Then we’ll have a_n = -2 + 9n -9 and well simplify even further.
-2 -9 = -11

So we get

a_n= 9n -11

The radius of the cone that holds ice cream which has height of 4.5 inches and 1.5π cubic inches, is 1 inches.

What is of volume of cone?

Volume of cone is the amount of quantity, which is obtained by the solid or object in the 3 dimensional space.

The volume of the cone can be given as,

[tex]V=\dfrac{1}{3}\pi r^2h[/tex]

Here, (r) is the radius of the base of the cone and (h) is the height of the cone.

The diagram of the cone is shown, in which,

The height of a cone that holds ice cream is 4.5 inches (h=4.5). The cone has a volume of 1.5π cubic inches (V=1.5π).

Let suppose the radius of the cone is r inches long. Thus, put the values in the above formula,

[tex]V=\dfrac{1}{3}\pi r^2h\\1.5\pi=\dfrac{1}{3}\pi r^2(4.5)\\1.5\pi\times3=\pi r^2(4.5)\\\dfrac{1.5\pi\times3}{\pi \times 4.5}= r^2\\1= r^2\\r=\sqrt{1}\\r=1\rm\; inches[/tex]

the weight of goats at a farm is normally distributed with a mean of 60 kg and a standard deviation of 10 kg. a truck used to transport goats can only accommodate not more than 650 kg. if 10 goats are selected at random from the population, what is the probability that the total weight exceeds the maximum weight?

Answers

Using the normal distribution, it is found that there is a 0.0571 = 5.71% probability that the total weight exceeds the maximum weight.

Normal Probability Distribution

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

In this problem, we have that the parameters are given as follows:

[tex]\mu = 60, \sigma = 10, n = 10, s = \frac{10}{\sqrt{10}} = 3.1623[/tex]

The probability that the total weight exceeds the maximum weight is the probability of a sample mean above 650/10 = 65 kg, which is one subtracted by the p-value of Z when X = 65.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{65 - 60}{3.1622}[/tex]

Z = 1.58.

Z = 1.58 has a p-value of 0.9429.

1 - 0.9429 = 0.0571.

0.0571 = 5.71% probability that the total weight exceeds the maximum weight.
