Answer:
2X+3+X-6 =180
3X-3+3=180+3
3X=183
X=61
Answer:
x = 61
Step-by-step explanation:
The angles shown form a straight line
Angles that form a straight line add up to equal 180
Hence, 2x + 3 + x - 6 = 180
( note that we just created an equation that we can use to solve for x )
We now solve for x using the equation created
2x + 3 + x - 6 = 180
step 1 combine like terms
2x + x = 3x
3 - 6 = - 3
we now have 3x - 3 = 180
step 2 add 3 to each side
-3 + 3 cancels out
180 + 3 = 183
we now have 3x = 183
step 3 divide 3 from each side
3x / 3 = x
183 / 3 = 6
we're left with x = 61

[tex] \large{ \boxed{ \tt{OUR \: ANSWER : \underline{ \$ \: 583.3125}}}}[/tex]
Well , You can solve this question using two ways. I'm gonna use the both ways to make you clear and the one which you can easily understand , pick up that way and start solving another question as similar as this one.
[tex] \large{ \tt{❃ \: FIRST \: METHOD }} : [/tex]
This method is related to the unitary method. Let's start :
We're provided - Amount Kelly earns per hour for gardening = $ 12.75 and we're asked to find out the amount she earn if she worked 45.75 hours this month.We know , Kelly probably earns more money if she worked 45.75 hours comparison to if she worked 1 hour. So You just multiply 45.75 & 12.75 , you would get $ 583.3125 and that's your final answer.[tex] \large{ \tt{❃ \: SECOND \: METHOD}} : [/tex]
This method is related to the proportion. If you haven't learned about it yet , use the above way to solve the similar type of questions. Let's start :
Let Kelly earns X dollars if she worked 45.75 hours this month. [ Now , See the attached picture ] Here , we can see the time is increased which implies that money will surely be increased. Such type of proportion is called direct proportion.Here , the ratio of time ( in hours ) = 1 : 45.75 and the ratio of amount ( in dollars ) = 12.75 : x . Now , Set up an equation and solve for x :[tex] \large{ \tt{ ❁ \: \frac{1}{45.75} = \frac{12.75}{x}}} [/tex]
[tex] \large{ \tt{↦ \: 1 \times x = 45.75 \times 12.75}}[/tex]
[tex] \large{ \tt{↦x = \$ \: 583.3125}}[/tex]
Hence , She earned $ 583.3125 .▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁

A florist has 1,276 flowers to divide into bunches of 9 flowers. The florist makes as many bunches as possible.
How many bunches of flowers does the florist make, and how many flowers are left over?
Enter your answers in the boxes.
The florist can make
bunches with
flowers left over.
Answers
Answer:
141 bunches, 7 flowers left
Step-by-step explanation:
Number of bunches of flowers that can the florist make is 23 flowers
What is ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
Here, we have,
If 60% of the flowers in a bunch are lilies,
then there are 40 x 0.6 = 24 lilies in each bunch.
That means there are 40 - 24 = 16 roses and carnations in each bunch.
The ratio of carnations to roses = 3 : 5
Let's call the number of carnations in each bunch "3x" and the number of roses in each bunch "5x". That means
3x + 5x = 16 (the total number of carnations and roses)
8x = 16
x = 2
So there are 3 x 2 = 6 carnations in each bunch.
If the florist has only 140 carnations, they can make 140 / 6 = 23.333... bunches of flowers. However, since they can't make a fraction of a bunch, the florist can only make 23 bunches of flowers.

For the function f(x) = -12x^2 + 6x - 8 find the equation of the tangent line at x= -1
Answers
Substitute x = -1 in f(x) we get y = -26
y = -12x^2+6x-8
Differentiate ‘y’ w.r.t ‘x’ we get
dy/dx = -24x+6
By putting value of ‘x’ we get
dy/dx = 30
Slope(m)=dy/dx = 30
Equation of tangent => (y - y1)=m(x - x1)
Here, x1= -1 and y1 = -26 and m = 30
So, (y - (-26)) =30(x - (-1))
y+26=30(x+1)
y+26=30x+30
30x - y + 4 =0 is the equation of tangent at x = -1

Phil's average is 0.250. This is about 5/6 as much as Joe's average. What is Joe's average? (Write answer is decimal form - do not round).
Answers
Let Joes average = x
Phil’s average is 0.250 and is 5/6X ( 5/6 of Joe’s)
5/6x = 0.250
Solve for x by dividing both sides by 5/6. When dividing by a fraction, flip the fraction over and multiply;
X = 0.250 x 6/5 = (0.250 x 6)/5 = 1.5/5 = 0.30
Joes average is 0.3
You are given a black box f : Z10 → Z10 that contains either a random permutation or a random function. Your distinguisher is allowed to invoke f twice. What is the best advantage you can achieve? Express your answer as a reduced fraction without any spaces (eg, 1/3 and not 12/36), or as 0 or 1 if appropriate.
Answers
Solution :
The function : [tex]$f: Z_{10} \rightarrow Z_{10}$[/tex] be a random permutation.
f is a permutation on [tex]$Z_{10}$[/tex] , i.e. f is permutation 10.
Now we know that the total number of distinct permutation on to symbolize 10!.
Each of these 10! permutation to a permutation function [tex]$f: Z_{10} \rightarrow Z_{10}$[/tex]
Therefore, total number of permutation functions [tex]$f: Z_{10} \rightarrow Z_{10}$[/tex] are 10!.
Now we want the total number of permutation functioning :
[tex]$f: Z_{10} \rightarrow Z_{10}$[/tex] such that f(0) = 0 and f(1)= 1
Now we notice that when f(0)=0 and f(1)=1, then two symbol '0' and '1 are fixed under permutation f.
So essentially when f(0) = 0 and f(1) = 1, f becomes permutation on 8 symbol.
Total number of permutation functioning [tex]$f: Z_{10} \rightarrow Z_{10}$[/tex] , f(0)=0 and f(1)=1 are 8!
Now we want the probability that a random permutation [tex]$f: Z_{10} \rightarrow Z_{10}$[/tex] satisfies f(0) = 0 and f(1) = 1.
The number of permutation function [tex]$f: Z_{10} \rightarrow Z_{10}$[/tex] , i.e.
The probability that a random permutation [tex]$f: Z_{10} \rightarrow Z_{10}$[/tex] satisfies f(0) = 0 and f(1) = 1 is
[tex]$\frac{8!}{10!} = \frac{8!}{10 \times 9\times 8!} =\frac{1}{10 \times 9}=\frac{1}{90}$[/tex]
Therefore, the probability that a random permutation [tex]$f: Z_{10} \rightarrow Z_{10}$[/tex] satisfies f(0)= 0 and f(1)=1 is [tex]$\frac{1}{90}$[/tex]

A poll found that 52% of U.S. adult Twitter users get at least some news on Twitter. The standard error for this estimate was 2.4%, and a normal distribution may be used to model the sample proportion. Construct a 99% confidence interval for the fraction of U.S. adult Twitter users who get some news on Twitter, and interpret the confidence interval in context. (Round your answers to two decimal places.)
Answers
Answer:
The 99% confidence interval for the fraction of U.S. adult Twitter users who get some news on Twitter is (0.46, 0.58). This means that we are 99% sure that the true proportion of all U.S. adult Twitter users who get some news on Twitter is between these two values.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].
A poll found that 52% of U.S. adult Twitter users get at least some news on Twitter. The standard error for this estimate was 2.4%
This means that:
[tex]\pi = 0.52, \sqrt{\frac{\pi(1-\pi)}{n}} = 0.024[/tex]
99% confidence level
So [tex]\alpha = 0.01[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.01}{2} = 0.995[/tex], so [tex]Z = 2.575[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.52 - 2.575(0.024) = 0.46[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.52 + 2.575(0.024) = 0.58[/tex]
The 99% confidence interval for the fraction of U.S. adult Twitter users who get some news on Twitter is (0.46, 0.58). This means that we are 99% sure that the true proportion of all U.S. adult Twitter users who get some news on Twitter is between these two values.

Answers
Answer:
x = 6
m<1 = 20°
m<CFE = 140°
Step-by-step explanation:
m<1 = (3x + 2)°
m<2 = (5x - 10)°
✔️Given that FB bisects AFC, therefore,
m<1 = m<2
Substitute
3x + 2 = 5x - 10
Collect like terms and solve for x
3x - 5x = -2 - 10
-2x = -12
-2x/-2 = -12/-2
x = 6
✔️m<1 = 3x + 2
Plug in the value of x
m<1 = 3(6) + 2
m<1 = 18 + 2
m<1 = 20°
✔️m<CFE = 180° - m<AFC (angles on a straight line)
m<CFE = 180° - (m<1 + m<2)
m<CFE = 180° - (20 + 20)
m<CFE = 180° - 40°
m<CFE = 140°

Answers
Answer:
y = $0.50x + $5. $7 if you went 4 miles
Step-by-step explanation:
$0.50 will be the coefficient for the variable x since the amount changes based on how many miles you ride. $5 will be the amount you are charged just for getting into the taxi and doesn't change depending on how many miles you go.
[tex]y=0.50x+5[/tex]

Answer:
Step-by-step explanation:
Any question that has less in it, is a question that you should pay attention to.
-7 -3 = - 10
You have to think of this the way you would money. Which would you rather owe - 7 dollars or - 10 dollars. Surely you would say that - 7 is better than - 10.
So - 10 looks like it is three less than - 7
It works if the money thing makes sense to you.
If that doesn't work then think of a number line. As you keep on going left, the number looks like it is getting bigger, but is it. Again - 10 is smaller than - 7.
If you are talking about plus numbers then 3 less then 7 is not 10. It is 4.
