Hello! Will someone please help me with expanding and simplifying this?:
3(m+2) + 4(6+m)
=============================================
Work Shown:
3(m+2) + 4(6+m)
3m+6 + 24 + 4m
(3m+4m) + (6+24)
7m+30
------------
Explanation:
In the second step, I used the distribution rule a*(b+c) = a*b+a*c. We multiply the outer term by every term inside. So for instance 3(m+2) = 3*m+3*2 = 3m+6. A similar situation applies to 4(6+m) as well. Afterward, I grouped and combined like terms.
We can think of 3m+4m = 7m as saying "I have 3 maps and someone gave me 4 more maps, so that means I have 3+4 = 7 maps now". The m is a place holder for any number.
Find f(-3)
Please help!
Answer:
-6
Step-by-step explanation:
anything for sangwoo
The numeric value of this expression is -6!
To find out what the value of this expression is, let's replace f(x) with f(-3) and perform the given math operations.[tex] \large \sf f(x) = 12 - 2x {}^{2} [/tex]
[tex] \large \sf f(-3) = 12 - 2\cdot (-3){}^{2} [/tex]
[tex] \large \sf f(-3) = 12 - 2\cdot 9 [/tex]
[tex] \large \sf f(-3) = 12 - 18 [/tex]
[tex] \boxed{ \boxed{{ \large \sf f(-3)=-6}}}[/tex]
Therefore, the result of this expression is f(-3)=-6. ✅

Solve the triangle. Round your answers to the nearest tenth.
Answer:
Area = 80 units²
Step-by-step explanation:
Given that:
a = 19 units
b = 9 units
c = 97°
Find the area of the triangle!
Area = ab(sin(c))/2
Area = [19×9×(sin(97))]/2
Area = 84.86 units²
Area = 80 units² ✅

To charter a fishing boat for 3 hours the captain charges a base fee of 45.00 plus 15.00 per person using variables construct a function that models the total cost of a 3-hour charter in terms of the number of people in your function. Define any variables you use. What is the correct interpretation of the initial value snd the rate of change
Answer:
$90.00
Step-by-step explanation:
Given
[tex]c = 45.00[/tex]--- base fee
[tex]m = 15.00[/tex] --- rate
[tex]x = 3[/tex] --- individuals
Required
Determine the total amount paid (y)
The relationship between the variables is:
[tex]Total = Base\ Fee + Rate * Individuals[/tex]
[tex]y = c + mx[/tex]
This gives:
[tex]y = 45.00 + 15.00 * 3[/tex]
[tex]y = 45.00 + 45.00[/tex]
[tex]y = 90.00[/tex]
Hence, the amount is $90.00

cancelStep-by-step explanation:
10) there are infinity values for k
4(k-8)=-32+4k
4k-32=-32+4k
these two equal each other so any value is equal to k
12) there are no values for b
-(3-6b)=6b+5
-3+6b=6b+5
the b's out and you are left with -3=5 which is impossible
Hope that helps :)

What property or theorrm would we have to use on these triangles to make them congruent
by ASA shortcut?
==============================================================
Explanation:
The diagram shows that we have two pairs of angles that are congruent. The angles with the single red arc pair up and are congruent, and the angles with the double arcs are the other congruent pair.
That takes care of the two "A"s in "ASA". As you can probably guess or know by now, "A" stands for "angle".
The only thing we need is the info about a pair of sides if they are congruent or not. In this case, we can see that the horizontal sides of the triangles are congruent since they overlap perfectly, or they are a shared common side. We use the reflexive property to say that "any segment is congruent to itself".

You deposit $3000 each year into an account earning 2% interest compounded annually. How much will you have in the account in 20 years?
Answer:
$72891.1094
Step-by-step explanation:
This method of saving is called sinking fund.
Future value (FV) = A*([tex]\frac{[(1+r)^{n} - 1]}{r}[/tex])
Where A is the amortization, r is the rate and n the number of years.
A = $3000
r = 2% = 0.02
n = 20
FV = 3000 * [tex](\frac{[(1.02)^{20} - 1]}{0.02})[/tex]
= 3000 * 24.2973698
= 72891.1094
FV = $ 72891.1094
The amount that would be in the account after 20 years is $72891.1094

Step-by-step explanation:
x/6 + 12 = -12
i don’t know what x is
Answer:
-144 is your answer for x.
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other.
Do the opposite of PEMDAS. PEMDAS is the order of operation, and stand for:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
First, subtract 12 from both sides of the equation:
x/6 + 12 (-12) = -12 (-12)
x/6 = -12 - 12
x/6 = -24
Next, isolate the variable x, by multiplying 6 to both sides:
(x/6) * 6 = (-24) * 6
x = -24 * 6
x = -144
-144 is your answer for x.

Akeem is making juice for a class party. For every 1 litre of water, he uses 100 ml of juice
mix
If he uses 4 litres of water, how many ml of juice does he use?
Answer:
400ml of juice
Step-by-step explanation:
1 litre of water = 100ml of juice
4 litres of water =? ml of juice
to get from 1 litre to 4 litre of water you multiply by 4,so you do the same for the juice and multiply the juice by 4.
100×4=400
4 litres of water = 400ml of juice

The temperature of a piece of metal was 32°C. It was then lowered into a glass of
hot water and the temperature of the piece of metal rose to 36°С. Find the
percentage increase in the temperature of the piece of metal.
Answer:
12.5%
Step-by-step explanation:
Given that,
Initial temperature of a piece of metal = 32°C
Final temperature of the piece of metal = 36°С
We need to find the percentage increase in the temperature of the piece of metal. The percentage increase in any value is given by the relation as follows :
[tex]\%=\dfrac{|\text{final value-initial value}|}{\text{initial value}}\times 100\\\\=\dfrac{36-32}{32}\times 100\\\\=12.5\%[/tex]
So, the required percentage increase in the temperature of the piece of metal is equal to 12.5%.

Suppose the weights of Farmer Carl's potatoes are normally distributed with a mean of 8.0 ounces and a standard deviation of 1.1 ounces.
(a) If 5 potatoes are randomly selected, find the probability that the mean weight is less than 9.3 ounces? Round your answer to 4 decimal places.
(b) If 6 potatoes are randomly selected, find the probability that the mean weight is more than 9.0 ounces? Round your answer to 4 decimal places.
Answer:
a) 0.9959 = 99.59% probability that the mean weight is less than 9.3 ounces
b) 0.0129 = 1.29% probability that the mean weight is more than 9.0 ounces
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Mean of 8.0 ounces and a standard deviation of 1.1 ounces.
This means that [tex]\mu = 8, \sigma = 1.1[/tex]
(a) If 5 potatoes are randomly selected, find the probability that the mean weight is less than 9.3 ounces?
[tex]n = 5[/tex] means that [tex]s = \frac{1.1}{\sqrt{5}} = 0.4919[/tex]
This probability is the pvalue of Z when X = 9.3. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{9.3 - 8}{0.4919}[/tex]
[tex]Z = 2.64[/tex]
[tex]Z = 2.64[/tex] has a pvalue of 0.9959
0.9959 = 99.59% probability that the mean weight is less than 9.3 ounces
(b) If 6 potatoes are randomly selected, find the probability that the mean weight is more than 9.0 ounces?
[tex]n = 6[/tex] means that [tex]s = \frac{1.1}{\sqrt{6}} = 0.4491[/tex]
This probability is 1 subtracted by the pvalue of Z when X = 9. So
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{9 - 8}{0.4491}[/tex]
[tex]Z = 2.23[/tex]
[tex]Z = 2.23[/tex] has a pvalue of 0.9871
1 - 0.9871 = 0.0129
0.0129 = 1.29% probability that the mean weight is more than 9.0 ounces
