Answer:
x = 65
Step-by-step explanation:
2x + 15 and 145 are vertical angles and congruent, then
2x + 15 = 145 ( subtract 15 from both sides )
2x = 130 ( divide both sides by 2 )
x = 65

The descriptions that accurately describe the relationship between AQRS and ATUV is they are similar and congruent. The correct options are B and C.
What are congruent angles?Angles with the same measure are said to be congruent. In other words, two angles are congruent if they open to the same degree.
Two angles of 60 degrees, for example, are congruent because they have the same measure.
Similar angles are those that have the same shape but differ in size. In other words, two angles are similar if they are scaled by the same factor and have the same degree of opening.
Two angles of 60 degrees, for example, are similar because they have the same shape; however, if one of the angles is scaled to be twice as large as the other, they remain similar angles.
Thus, as per the given image, the correct options are B and C.

Your bill for lunch was $12.86. How much would 20% tip be? What would your total be with tip included? Explain how you used math to come to your decision.
Answers
20% Tip = $2.58 Total Amount: $15.43
Step-by-step explanation:
An easy way to solve a problem, where the percentage ends in a 0, is to find 10% of the original number. 12.86 is our starting number, so finding 10% of that is simply moving the decimal place 1 to the left, making 10% = 1.29.
To find 20% Just Multiply 1.28 (10%) by 2, which is 2.58. Add this amount to 12.86 and you get $15.43.
Another way to solve the problem is simply to multiply $12.86 * 1.20, which would give you $15.43 as well.

This table gives the value of an investment for the first 5 years after the initial investment was made. The data can be modeled using an exponential function.
Years 1 2 3 4 5
Investment value $1,050 $1,103 $1,160 $1,215 $1,280
Based on the data, which amount is closest to the value of the investment 10 years after the initial investment?
$1,350
$1,475
$1,625
$1,800
Answers
Answer:
C.) $1,625
Step-by-step explanation:
Going by the numbers on the graph, you can immediately tell $1,350 and $1,475 are way too low, so cancel those out and you get $1,625 and $1,800
From here, you can see that in 5 years it hasn't gone up by far, so it won't be 1,800$ by 10 years end, making the answer clear
You can just double 280 and get 560, which the closest answer is 1,625
It's really just a high-low estimate question, 2 answers are too high or low, one is close but not really, and one is just right- or inbetween
$1,625
The amount $1625 is closest to the value of the investment 10 years after the initial investment option third is correct.
What is an exponential function?It is defined as the function that rapidly increases and the value of the exponential function is always a positive. It denotes with exponent [tex]\rm y = a^x[/tex]
where a is a constant and a>1
Let's suppose the exponential function that model the problem is:
[tex]\rm y = ae^k^x[/tex]
Plug x = 1 and y = 1050
[tex]\rm 1050 = ae^k[/tex] ...(1)
Plug x = 2 and y = 1103
[tex]\rm 1103 = ae^2^k[/tex] ...(2)
Divide equation (2) with (1)
[tex]\rm e^k = 1.0504[/tex]
Taking ln to get the value of k
k = 0.0491
a = 999.69
The exponential function:
[tex]\rm y = (999.6902)e^{0.0491}^x[/tex]
Plug x = 10 years in the above function:
y = $1633.44
Which is close to $1625
Thus, the amount $1625 is closest to the value of the investment 10 years after the initial investment option third is correct.

A boat is traveling at 43.2 m/s. It then goes down a faster part of the river and is now going 144
m/s which gave the boat an acceleration of 25.2 m/s2. How long did it take the boat to reach its
new speed?
Answers
Answer:
Step-by-step explanation:
boat was at 43.2 m/s speed increase to 144 m/s
if the boat was moving 0 m/s and increased to 144 m/s - 43.2 m/s accelerating at 25.2 m/s², it would take the same amount of time
25.2 m/s² × x seconds = (144 - 43.2) m/s solve for x in seconds
x seconds = 100.8 m/s / 25.2 m/s²
x seconds = 4 (m/s /ms²) = 4 (m/s × s²/m) = 4 seconds the units match
x = 4 seconds
