Step-by-step explanation:
Find the unknown angle measures.
Answer:
x = 9°
y = 119°
Step-by-step explanation:
Given,
y° = 61°+58° { the exterior angle formed by producing the side of triangle is equal to two non-adjacent angle}
or, y° = 119°
therefore, y° = 119°
Now,
52°+y°+x° = 180°{the sum of angle if triangle is 180°}
or, 52°+119°+x°= 180°
or, 171°+x° = 180°
or, x° = 180°-171°
or, x° = 9°
therefore, x° = 9°

Perfect Purple Water The recipe for Perfect Purple Water says, "Mix 8 ml of blue water with 3 ml of red water." lada mixes 24 ml of blue water with 9 ml of red water. Andre mixes 16 ml of blue water with 9 ml of red water. . Which person will get a color mixture that is the same shade as Perfect Purple Water? Explain or show your reasoning.
Analysing the question:
We are given that the ratio between the blue and red color is 8 : 3
as long as the volumes of the colours added simplify to 8 : 3 , the color will be Perfect Purple
Lada's Solution:
Lada mixed 24 mL of blue water with 9 mL of red water
we will try to simplify this ratio:
24:9 = 24 / 9
8 / 3
8 : 3
Hence, the ratio of the colours in Lada's mixture is correct. So, Lada will get perfect purple water
Andre's Solution:
Andre mixed 16mL of Blue water with 9 mL of red water
we will try to simplify this ratio:
16 : 9 = 16 / 9
THIS RATIO CANNOT BE SIMPLIFIED
Hence, the ratio of blue and red color in Andre's mixture is 16 : 9
but the ratio for a perfect purple color is 8 : 3
Since the ratio in Andre's mixture is incorrect, she will NOT get the perfect purple colour
Answer:
Lada will get a color mixture that is the same shade as Perfect Purple Water.
Step-by-step explanation:
Proportions
The mix for Perfect Purple Water contains 8 ml of blue water with 3 ml of red water.
The exact proportion of both ingredients is, blue to red:
[tex]\displaystyle \frac{8}{3}[/tex]
Lada mixes 24 ml of blue water with 9 ml of red water. The proportion is:
[tex]\displaystyle \frac{24}{9}[/tex]
Simplifying by 3:
[tex]\displaystyle \frac{8}{3}[/tex]
The proportion obtained by Lada is the same shade as Perfect Purple Water.
Andre mixes 16 ml of blue water with 9 ml of red water, his proportion is:
[tex]\displaystyle \frac{16}{9}[/tex]
This fraction cannot be reduced and its result is not exactly the same as the perfect required proportion.
Thus, Lada will get a color mixture that is the same shade as Perfect Purple Water.
For a polynomial P(x), the quotient P(x)/(x-2) has a remainder of 12. What is the value of P(2)? Please explain. Thanks :)
Answer:
12
Step-by-step explanation:
P(x) has infinitely many solutions, but I am going to find the easiest one, which would be a linear equation.
First, notice that x-2 perfectly divides into itself.
Then, if you add 12 to x-2, you will end up with a remainder of 12. Therefore, P(x) would be x-2+12 = x+10.
Now that we know P(x), we can directly plugin 2 to find out P(2):
2+10 = 12
Therefore, P(2) = 12.

ben is training for a triathlon he runs 1/5 of a mile in 1/20 of an hour he seems to third of a mile in 1/9 of an hour he bikes for miles in 1/4 of an hour at this rate how many minutes does it take them to run 2 miles swim 2 miles in bike 8 miles
Answer:
a) He will take 76 minutes in the triathlon
Step-by-step explanation:
He runs 1/5 of a mile in 1/20 f hour then, by simple inspection
1/5 ⇒ 1/20 then 1/5 miles* 10 = 2 miles
1/20*hours*10 = 1/10 hours
10/10 of an hour is 60 minutes
1/10 of an hour is 6 minutes
swimming
1/3 of a mile in 1/9 of hours then
1/3mile *6 = 2 miles
1/9 of an hour * 6 = 6/9 hours or 2/3 of an hour
3/3 of an hour is 1 hour = 60 minutes
2/3 of an hour is = 40 minutes
In bike
4 miles in 1/4 hour then
4 miles *2 = 8 miles
1/4 hour* 2 = 1/2 hour = 30 minutes
Then he will do the triathlon in:
6 minutes running
40 minutes swimming
30 minutes in bike
Total 76 minutes
Find the remainder when
f(x) = 8x^3 + 4x^2 – 13x + 3
is divided by 2x + 5.
A. 1241/125
B. -129/2
C. 69/125
D. 183
Dividing f(x) by 2x + 5 leaves the same remainder as division by x + 5/2. By the remainder theorem, it is equal to f (-5/2), so the remainder here is
f (-5/2) = 8 (-5/2)³ + 4 (-5/2)² - 13 (-5/2) + 3 = -129/2
12.1.33 Question Help Suppose that 62% of families living in a certain country own an HDTV and 16% own a computer. The Addition Rule might suggest, then, that 78% of families own either an HDTV or a computer. What's wrong with that reasoning?
Answer:
Step-by-step explanation:
Suppose :
62% own an HDTV
16% own a computer
Using the addition rule : suggests that (62% + 16%) = 78% either own an HDTV or a computer.
The reasoning is wrong because ; since it is possible to own both an HDTV and also own a computer at the same time, the outcome of the addition rule is wrong as both events are independent. If both event cannot occur at the same time (mutually exclusive event) , then, the addition rule may be applied,. But since both can occur independently and each family can own an HDTV while also owning a computer, then the addition rule is wrong for the scenario described.

The residents of a certain dormitory have collected the following data: People who live in the dorm can be classified as either involved in a relationship or uninvolved. Among involved people, 5 percent experience a breakup of their relationship every month. Among uninvolved people, 10 percent enter into a relationship every month. What is the steady-state percentage of residents who are uninvolved
Answer:
The steady-state percentage of residents who are uninvolved = 0.33%
Step-by-step explanation:
This is an example of the natural rate of unemployment given the steady-state percentage of residents who are uninvolved in the question. From the question, the break-up rate represents the rate of job separation in the natural rate of unemployment, while the rate that enters into a relationship represents the rate of job finding in the natural rate of unemployment.
The formula for the natural rate of unemployment = U/L = s / (s + f)
So, the steady-state percentage of residents who are uninvolved = U/L = s / (s + f)
Where U/L = natural rate of unemployment
s = rate of job separations
f = rate of job finding
s = 5 percent
f = 10 percent
The steady-state percentage of residents who are uninvolved
= 5% / (5% + 10%)
= 0.33%

12. According to a survey conducted by the American Pet Products Association, 68% of U.S. households own a pet. According to the Energy Information Administration, 31% of all U.S. households have trouble paying their energy bills. Suppose 17% of all U.S. households own a pet and have trouble paying their energy bills. If a U.S. household is randomly sampled, a. What is the probability that the household owns a pet or is having trouble paying energy bills
Answer:
0.82
Step-by-step explanation:
We are given;
P(households own a pet) = 68% = 0.68
P(have trouble paying their energy bills) = 31% = 0.31
P(households own a pet & have trouble paying energy bills) = 17% = 0.17
Now, to find the probability that a household either owns a pet or having trouble paying energy bills is gotten by the relationship;
P(households own a pet or have trouble paying energy bills) = P(households own a pet) + P(have trouble paying their energy bills) - P(households own a pet & have trouble paying energy bills)
This gives;
P(households own a pet or have trouble paying energy bills) = 0.68 + 0.31 - 0.17 = 0.82
(25 points) A car rental company's standard charge includes an initial fee plus an additional fee for each mile driven. The standard charge S (in dollars) is given by the function S = 0.40M + 15.75, where M is the number of miles driven.
The company also offers an option to insure the car against damage. The insurance charge I (in dollars) is given by the function I = 0.25M + 3.90.
Let C be the total charge (in dollars) for a rental that includes insurance. Write an equation relating C to M. Simplify your answer as much as possible.
C =
Answer:
C = 0.65M+19.65
Step-by-step explanation:
Given the the standard charge S (in dollars) given by the function
S = 0.40M + 15.75, where M is the number of miles driven.
Also the insurance charge I (in dollars) is given by the function
I = 0.25M + 3.90
If C is the total charge (in dollars) for a rental that includes insurance, then:
C = S + I
Substitute the given function into the expression:
C = 0.40M + 15.75 + 0.25M + 3.90
Collect like terms
C = 0.40M+0.25M+15.75+3.90
C = 0.65M+19.65
Hence an equation relating C to M is expressed as C = 0.65M+19.65
