Step-by-step explanation:
6x-1+3x+5x+3+4x+8+5x+5=360 degree(sum of exterior angle of a pentagon is 360 degree)
23x+15=360
23x=360-15
x=345/23
x=15
therefore the value of x is 15 degree.

Answers
Answer:
2k + 4
Step-by-step explanation:
David,
Start by performing the indicated multiplication:
5(k+2)-3(k+2) becomes 5k + 10 - 3k - 6.
Next, combine like terms: 5k - 3k + 10 - 6 becomes 2k + 4
This 2k + 4 is the desired simpler result.

To solve a system of inequalities, you just need to graph each inequality and see wich points are in the overlap of the graphs.
True or false?
Answers
This is often how many math teachers and textbooks approach problems like this. The overlapped region is the region in which satisfies every inequality in the system. Be sure to note the boundary of each region whether you're dealing with a dashed line or a solid line. Dashed lines mean points on the boundary do not count as solution points, whereas solid boundaries allow those points as part of the solution set.
Side note: This is assuming you're dealing with 2 variable inequalities. If you only have one variable, you don't need to graph and instead could use algebra. Graphing doesn't hurt though.

Answers
Answer:
0.8214
Step-by-step explanation:
We have
F(x) = 1/b-a
With b = 7
And a = 0
Such that we have
1/7-0
= 1/7
Probability of x> 1.25
7-1.25
= 5.75
1/7 x 5.75
= 0.8214
Therefore the probability that a randomly selected passenger has a waiting time more than 1.25 minutes is = 0.8214.

the equation s=2√5x can be used to estimate the speed ,s,of a car in milles per hour, given the length in feet ,x, of the tire marks it leaves on the ground .A card travelling 90 miles per hour came to a sudden stop according to the equation ,how long would the tire marks be for this car A 355 feet B 380 feet C 405 feet D 430 feet
Answers
Answer:
405 feet
Step-by-step explanation:
s = 2 * (√5) * 90
s = 2 * 201.246117975
s = 402.49223595
Closest estimate
405 feet
Answer:
Since The equation that depicts the motion of the Car is given.
The speed in terms of the tire marks...
s= 2√5x
where x is the tire marks(in feet.)
s is the speed(miles per hr)
We can't use the speed in Miles per hr when the tire mark is feet.
1mile = 5280ft
90miles x 5280ft/1mile = 475,200ft/hr
Making x the subject
x= s/2√5
x= 475/200/(2√5 )
=106,257ft

Let g(t)= t−16 t−4. a. Make two tables, one showing the values of g for t=15.9, 15.99, and 15.999 and one showing values of g for t=16.1, 16.01, and 16.001. b. Make a conjecture about the value of limt→16 t−16 t−4.
Answers
Answer:
[tex]\lim_{t \to \ 16} (t-16)(t-4) =0[/tex]
Step-by-step explanation:
g(t)= (t-16)(t-4)
(a) Then, we have,
t g(t)
15.9 -1.19
15.99 -0.1199
15.999 -0.011999
Also, we have,
t g(t)
16.1 1.21
16.01 0.1201
16.001 0.012001
(b) We can see, from the above table that as 't' tends to 16 from the left hand side, the value of g(t)= (t-16)(t-4) is tending to 0 from the negative direction.
Similarly, from the second table, we can see that as 't' tends to 16 from the right hand side, the value of g(t)= (t-16)(t-4) is tending to 0 from the positive direction.
Thus, we can say that [tex]\lim_{t \to \ 16-} (t-16)(t-4)[/tex] & [tex]\lim_{t \to \ 16+} (t-16)(t-4)[/tex], i.e., the left hand limit and right hand limit of g(t)= (t-16)(t-4), at t=16, both exist and is both equal to 0.
Since both these limits exist and are equal, we can say, [tex]\lim_{t \to \ 16-} (t-16)(t-4) = \lim_{t \to \ 16+} (t-16)(t-4) = \lim_{t \to \ 16} (t-16)(t-4) = 0[/tex]

Answers
Answer:

Step-by-step explanation:
The mean of a standard normal distribution is always = 0 with the standard deviation being equal to. Therefore a standard normal distribution is a normal distribution described with a mean of 0 and standard deviation of 1. Since a standard normal distribution is centered at the middle with equal distribution to both the left and right of the distribution. The centre point is 0, which is the mean and the standard deviation is 1 to either side of the distribution.

Answer:
44
Step-by-step explanation:
Step 1: Create an equation to solve for ∠Z
Recall that trig ratio tangent = Opposite over Adjacent
Opposite of ∠Z = 75 and adjacent of ∠Z = 79
Hence, [tex]tan(z)=\frac{75}{79}[/tex]
We now solve for z
Step 1: Multiply each side by the inverse of tan ( tan ) ^-^1
[tex]tan(z)*tan^-^1=z\\tan^-^1(\frac{75}{79} )=43.51213147[/tex]
We're left with z = 43.51213147
Our last step is to round to the nearest degree,
We get that ∠Z = 44

Answer:

Step-by-step explanation:
1. First change the mixed fractions to improper fractions so it's easier
[tex]\frac{16}{5\\}/(z-\frac{1}{2}) = \frac{8}{3}/(z+\frac{1}{3})[/tex]
2. Simplify
[tex]\frac{32}{5(2z-1)} = \frac{8}{3z+1}[/tex]
3. Cross multiply
[tex]32(3z+1) = 5(2z-1) * 8[/tex]
4. Simplify again (distributive property)
[tex]32(3z+1) = 40(2z-1)[/tex]
5. Distributive property
[tex]32(3z+1) -> 96z+32[/tex]
[tex]40(2z-1) -> 80z-40[/tex]
[tex]96z+32=80z-40[/tex]
6. Subtract 32 from both sides
[tex]96z+32-32 = 80z-40-32[/tex]
7. Simplify
[tex]96z = 80z-72[/tex]
8. Subtract 80 from both sides
[tex]96z-80z=80z-72-80z[/tex]
9. Simplify
[tex]16z=-72[/tex]
10. Divide both sides by 16
[tex]\frac{16z}{16}=\frac{-72}{16}[/tex]
11. Simplify
[tex]z=-\frac{9}{2} -> also = -4\frac{1}{2}[/tex]

An advertising company charges $40 per half - page advertisement and $75 per full-page advertisement. Michael has a budget of $800 to purchase 13 advertisements. A) Define a variable for each unknown. Write a system of equations to represent the situation. B( How many half-page advertisements does Michael purchase? Show Your Work. C) How many full-page advertisements does Michael purchase? Show your Work. ( Will Mark Brainliest but have to show work) Answer A, B & C. No links or nonsense answers please.
Answers
40h + 75f = 800. Assuming budget is fully spent
h + f = 13
B) 75h + 75f = 975 (multiplying the second equation by 75)
35h = 175 (subtracting the first equation)
h = 5
Michael purchases 5 half page adverts
C) 5 + f = 13 (Substituting for h in second equation)
f = 8
Michael purchases 8 full page adverts
The number of half page advertisements that Michael purchased is 5 while the full page advertisements is 8.
Let the number of half page ads be represented by h
Let the number of full page ads be represented by f.
Therefore, the system of equations to represent the situation will be:
h + f = 13 ....... i
40h + 75f = 800 ........ ii
From equation i,
h = 13 - f ....... equation iii
Put the value of h into equation ii
40h + 75f = 800
40(13 - f) + 75f = 800
520 - 40f + 75f = 800
Collect like terms
75f - 40f = 800 - 520
35f = 280
f = 280/35
f = 8
The number of full-page advertisements that Michael purchased is 8.
Since h + f = 13
h + 8 = 13
h = 13 - 8
h = 5
The number of half page advertisements that Michael purchased is 5.
