Answer:
Sum of supplementary angles is 180°
6x+9x=180
15x=180
x= 12
9x=108°
Step-by-step explanation:
The supplementary angles having ratio 6:9 are 72° and 108°.
What are supplementary angles?Supplementary angles are those angles which is having sum of 180 degrees. Opposite of supplementary angles are complementary angles.
How to find angles?We have been given that the ratio of two supplementary angles is 6:9. So, the angles are 6x and 9x. According to question and definition of supplementary angles we can write the angles in the following form:
6x+9x=180°
Now find the sum of left side and put it equal to 180.
15x=180
x=180/15
x=12
Putting in the values of angles we will find the following:
Angle 1=6x=6*12=72°
Angle 2=9x=9*12=108°.
Hence the supplementary angles having ratio 6:9 are 12° and 108°.

Answer:
y = -1/2
Step-by-step explanation:
5^3 = (5^-2)^y-1
3 = -2(y-1)
3 = -2y + 2
1 = -2y
y = -1/2
Solve using substitution. I know that the answer is (1,1), but I have to show my work and I forgot how to do it.
If y = -x + 2, then substituting this into the first equation lets you solve for x :
x + 4y = 5
x + 4 (-x + 2) = 5
x - 4x + 8 = 5
-3x = -3
x = 1
Now solve for y :
y = -x + 2 = -1 + 2 = 1
So the solution is indeed (x, y ) = (1, 1).

The corporate office building is 50m high and angle of elevation at top of building is 52° when seen from a point on level ground. The distance between point and foot of the building is
Answer:
39.06 m
Step-by-step explanation:
Given that,
Height of the building, h = 50 m
The angle of elevation at top of building is 52° when seen from a point on level ground.
We need to find the distance between point and foot of the building. Let the distance be d. Using trigonometry to find it. So,
[tex]\tan\theta=\dfrac{P}{B}[/tex]
Where
P is perpendicular
B is base.
So,
[tex]\tan\theta=\dfrac{h}{d}\\\\d=\dfrac{h}{\tan\theta}\\\\d=\dfrac{50}{\tan(52)}\\\\d=39.06\ m[/tex]
So, the distance between point and foot of the building is 39.06 m
Applying the trigonometry ratio, TOA, the distance between the point and the foot of the building is: 39.1 m.
Recall:
SOH CAH TOA are the common trigonometry ratios that can be used to solve a right triangle.The information of the building has been sketched in the diagram shown in the image attached below. It shows a right triangle.
The distance between the point on the ground and the foot of the building = x (adjacent)Reference angle (∅) = 52°Opposite side = 50 mApply the trigonometry ratio, TOA:
tan ∅ = opposite/adjacent
Substitutetan 52 = 50/x
x = 50/tan 52
x = 39.1 m
Therefore, applying the trigonometry ratio, TOA, the distance between the point and the foot of the building is: 39.1 m.

Carl is choosing a four-character password for his cell phone. The password can contain letters and digits only, and can't include repeating characters. How many passwords are possible?
Answer:
Step-by-step explanation:
i feel like it would be (4)(4)(4)(4)(4)(4)(4)(4) = 65536
The number of different four digit passwords that are possible if we use letters and digits only, and can't include repeating characters is 13,388,280 ways.
How many ways k things out of m different things (m ≥ k) can be chosen if order of the chosen things doesn't matter?We can use combinations for this case,
Total number of distinguishable things is m.
Out of those m things, k things are to be chosen such that their order doesn't matter.
This can be done in total of [tex]^mC_k = \dfrac{m!}{k! \times (m-k)!}[/tex] ways.
If the order matters, then each of those choice of k distinct items would be permuted k! times.
So, total number of choices in that case would be:
[tex]^mP_k = k! \times ^mC_k = k! \times \dfrac{m!}{k! \times (m-k)!} = \dfrac{m!}{ (m-k)!}\\\\^mP_k = \dfrac{m!}{ (m-k)!}[/tex]
This is called permutation of k items chosen out of m items (all distinct).
For this case, we assume that:
"Letters" are denoting uppercase and lowercase english alphabets (26 uppercase, and 26 lowercase, so total 52 such letters).
And digits are denoting (0,1,2,3,4,5,6,7,8,9) so total 10 such digits.
Thus, total 52+10 = 62 different choices to choose from.
Of these 62 options, we can use one letter only one time in a password.
Choosing any 4 characters out of those 62 characters is done in:
[tex]^{62}C_4 = \dfrac{62 \times 61 \times 60 \times 59 \times 58!}{4 \times 3 \times 2 \times 1 \times 58!} = 557845[/tex] ways.
Each of those 4 selections have distinct characters, and in a password, their arrangement matters, so each of those 557845 choices can be permuted in 4! ways.
Thus, total number of distinct 4 digit password out of 52 english letters and 10 digits is [tex]4! \times 557845 = 24 \times 557845= 13388280[/tex] ways. (or we could've directly evaluated [tex]^{62}P_4[/tex]
Thus, the number of different four digit passwords that are possible if we use letters and digits only, and can't include repeating characters is 13,388,280 ways.

philip has 11 coins that equal a total of 82 cents. His coins include at least 1 quarter 1 dime 1 nickel and 1 penny. how many of each coin does he have
Answer:
Philip has 1 Quarter, 3 Dimes, 5 Nickels, and 2 Pennys.
Step-by-step explanation:
Given that Philip has 11 coins that equal a total of 82 cents, and his coins include at least 1 quarter 1 dime 1 nickel and 1 penny, to determine how many of each coin does he have the following calculation must be performed:
Quarter = 0.25
Dime = 0.10
Nickel = 0.05
Penny = 0.01
0.82 - 0.25 - 0.10 - 0.05 - 0.01 = 0.41
0.41 = 0.10 x 4 + 0.1 (5 coins + 4 previous coins = 9 coins).
0.41 = 0.10 x 2 + 0.05 x 4 + 0.01 (7 coins + 4 previous coins = 11 coins).
0.25 + (3 x 0.1) + (5 x 0.05) + (2 x 0.01) = X
0.25 + 0.30 + 0.25 + 0.02 = X
0.82 = X
Thus, Philip has 1 Quarter, 3 Dimes, 5 Nickels, and 2 Pennys.
70x + 25 = 50x +75
How many hours of service do the services cost the same?
Answer:
2.5 hours
Step-by-step explanation:
70x+25=50x+75
step 1 subtract 25 from each side
25-25 cancels out
75-25=50
Now we have
70x=50x+75
step 2 subtract 50 from each side
70x-50x=20x
50x-50x cancels out
now we have
20x=50
step 3 divide each side by 20
20/20 cancels out
50/20=5/2 or 2.5
so we can conclude that it will take 2.5 hours of service for the services to cost the same
Hello, can someone please assist me with this question?

Hey There!
If you didnt know the given angles in the triangle added together equal the missing triangles supplement aka z+50
So all we have to do is set up an equation
z+50=30+6x-45
step 1 combine like terms
30-45=-15
now we have
z+30=6x-15
step 2 add 15 to each side
-15+15 cancels out
30=15=45
now we have
z+45=6z
step 3 subtract z from each side
z-z cancels out
6z-z=5z
now we have
45=5z
step 4 divide each side by 5
5/5 cancels out
45/5=9
z=5
so we can conclude that z=9
