29 degrees C to Fahrenheit.
Answer:
29 degrees Celsius are 84.2 Fahrenheit.
Step-by-step explanation:
In order to convert Celsius to Fahrenheit you can use this formula: [tex]F = C * 1.8 + 32[/tex].
Here we have [tex]F = 29 * 1.8 + 32[/tex] which equals 84.2. Instead of 1.8 you can use the fraction [tex]\frac{9}{5}[/tex] if you wish so.
Answer:
[tex]\large\boxed{29^oC=84.2^oF}[/tex]
Step-by-step explanation:
Formula for converting Celsius (C) to Fahrenheit (F):
[tex]F=32+\dfrac{9}{5}C[/tex]
We have C = 29. Substitute:
[tex]F=32+\dfrac{9}{5}(29)=32+\dfrac{261}{5}=32+52.2=84.2[/tex]

Hey!
----------------------------------------------------
Solution:
2x - 3|x + 1| = -2x - 11
2x - 3|x + 1| + (-2x) = -2x - 11 + (-2x)
-3|x + 1| = -4x - 11
-3|x + 1|/-3 = -4x - 11/-3
|x + 1| = 4/3x + 11/3
x + 1 = -(4/3x + 11/3)
x + 1 + 4/3x = 4/3 + -11/3 + 4/3x
7/3x + 1 = -11/3
7/3x + 1 - 1 = -11/3 - 1
7/3x = -14/3
7/3x * 3/7 = -14/3 * 3/7
x = -2
----------------------------------------------------
Check:
2(-2) - 3|-2 + 1| = -2(-2) - 11
(-4) - 3|-1| = (4) - 11
(-4) - 3 = (4) - 11

Reflect (4,-9) across the y-axis. Then reflect the result across the x-axis. What are the coordinates of the final point?
Answer: (-4,9)
Step-by-step explanation:
After applying the sequence of transformations, the coordinates of the final point are (-4, 9).
How to determine the new vertices or coordinates of the image?In Mathematics and Geometry, a reflection over or across the y-axis would maintain the same y-coordinate while the sign of the x-coordinate changes from positive to negative or negative to positive.
By applying a reflection over the y-axis to the coordinates of the point (4, -9), we have the following new coordinates for the image;
(x, y) → (-x, y)
(4, -9) → (-4, -9)
By applying a reflection over the x-axis to the coordinates of the point (-4, -9), we have the following new coordinates for the image;
(x, y) → (x, -y)
(-4, -9) → (-4, -(-9)) = (-4, 9)

You are competing in a race. The table shows the times from last year's race you want your time to be last year's median time with an absolute
deviation of at most 5 minutes. Complete the inequality to represent the time in minutes) you hope to achieve
Answer:
[tex]27\leq x \leq37[/tex]
Step-by-step explanation:
Let's arrange the numbers from least to greatest:
20, 25, 27, 28, 31, 32, 32, 38, 40, 40, 42, 48
The median is the "middle" number when arranged from least to greatest.
There are 12 numbers, so the middle number would be "average" of 6th and 7th terms.
6th term = 32
7th term = 32
Average = (32+32)/2 = 32
Hence, median = 32
Absolute deviation of 5 minutes means 5 minutes less or greater than the median, 32.
So, 32 - 5 = 27 & 32 + 5 = 37
Hence [tex]27\leq x \leq37[/tex]
To find the inequality range for race times, we must first arrange the times and find the median, which is 32 minutes. The desired race time with an absolute deviation of at most 5 minutes from the median results in the inequality 27 ≤ x ≤ 37.
Explanation:
To solve this problem, we need to arrange the given race times in order and find the median. Once we find the median, we can set up an inequality that represents a race time within 5 minutes more or less than this median time.
First, we arrange the race times in ascending order: 20, 31, 27, 32, 25, 42, 48, 28, 40, 38, 32. After putting them in the proper order (20, 25, 27, 28, 31, 32, 32, 38, 40, 42, 48), we find that the median, which is the middle value, is 32 minutes since there are 11 times, and the 6th time is the median.
Next, we want to have a race time with an absolute deviation of at most 5 minutes from the median (32 minutes). This gives us the inequality 27 ≤ x ≤ 37. So, the time you hope to achieve in the race is between 27 and 37 minutes.

What is 7909+1044 using algorithm
Answer:
8,953
Step-by-step explanation:
line up 7,909 and 1,044 like this :
7,909
+ 1,044
then add everything
Using the addition algorithm, first you align the numbers by place value, then starting from the rightmost position, you add each place numbers together. Accordingly, 7909 + 1044 equals 8953.
Explanation:The process of adding two numbers using the additon algorithm begins with lining up the numbers by their place values. Starting from the rightmost digit, which is the one's place, you add the numbers in each corresponding place together.
In this case, Adding 7909 and 1044:
You begin with the ones place (9+4), which equals 13. You put down the 3 and carry over the 1 to the next place. After the first step the result would look like this: 790_3 with 1 carried over. Next, you add the numbers in the tens place (0+4) and the carried over 1, which equals 5. So the result after the second step would look like this: 79_53. You then move to the hundreds place. Since there is no number to add with 9, you simply carry it down. So the result after the third step would look like this: 7_953. Finally, you add the numbers in the thousands place (7+1), which equals 8. Therefore, the final result of 7909 + 1044 using the addition algorithm is 8953. Learn more about Addition Algorithm here:

two angels are complementary one angle measures 3more than twice the other.
Answer:
29° and 61°
Step-by-step explanation:
Complementary angles sum to 90°
let one angle be x then the other angles = 2x + 3
Sum the angles and equate to 90
x + 2x + 3 = 90, that is
3x + 3 = 90 ( subtract 3 from both sides )
3x = 87 ( divide both sides by 3 )
x = 29
and 2x + 3 = (2 × 29) + 3 = 58 + 3 = 61
The two angles are 29° and 61°

Janine is analyzing spending habits of students in her high school. She finds a mean monthly discretionary expense of $70 spent on having meals out with friends the standard deviation of the distribution is five. What is the variance?
Answer:
Variance = 25
Step-by-step explanation:
Standard deviation is the under root of variance.
Variance is the square of standard deviation.
Data:
Mean = 70
Variance = ?
Standard deviation = √variance = 5
Variance = 5²
Variance = 25.
Therefore, the variance is 25.
Final answer:
The variance of the monthly discretionary expenses on meals out with friends is 25 dollars squared.
Explanation:
To find the variance of Janine's data on the spending habits of students for meals out with friends, you'll use the squared value of the standard deviation.
Since Janine found the standard deviation to be five dollars, you simply need to square this number to find the variance.
Step-by-step Calculation:
Identify the standard deviation (denoted as σ) which is 5.Square the standard deviation to find the variance: Variance = σ² = 5².Calculate the squared value: 25.The variance of the distribution of monthly discretionary expenses on meals out is 25 dollars squared.
Ava’s newest financial goal is to eliminate the remainder of her student loan debt. She has about $8,950 left on her student loans. She determines that she can afford to make monthly payments of about $360. To track her progress, she plans to create a graph to model her situation. How should Ava label and scale her graph?
A.
x-axis scale, 0–20; label, Total Remaining Debt ($)
Y-axis scale, 0–9,000; label, Months
B.
x-axis scale, 0–30; label, Months
Y-axis scale, 0–9,000; label, Total Remaining Debt ($)
C.
x-axis scale, 0–20; label, Years
Y-axis scale, 0–9,000; label, Total Remaining Debt ($)
D.
x-axis scale, 0–30; label, Total Remaining Debt ($)
Y-axis scale, 0–9,000; label, Years
E.
x-axis scale, 0–20; label, Total Remaining Debt ($)
Y-axis scale, 0–9,000; label, Years
Answer:
B.
x-axis scale, 0–30; label, Months
Y-axis scale, 0–9,000; label, Total Remaining Debt ($)
Step-by-step explanation:
According to given data
Debt = $8950
Monthly payment = $360
Now we can calculate the total period required to eliminate the debt
Total months to eliminate debt = Total Debt/Monthly installment
Total months to eliminate debt = 8950/360
Total months to eliminate debt = 24.8 months
Now, by this calculate, we can say that it is only logical to plot time in graph with months, not years or days. Because if we plot graph with days, it will be too lengthy, on the other hand, if we plot graph with years, it will shrink to much and it will become very difficult to read it and estimate the progress. So all options with time in other than month will be eliminated and we will be left with option B. Notice that option a will be eliminated because we need to plot graph for 24.8 months but it contains 9000 months, which means 750 years. So it will be illogical to plot graph on this scale.
Answer:
x-axis scale, 0–30; label, Months
y-axis scale, 0–9,000; label, Total Remaining Debt ($)
Step-by-step explanation:
For the time scale you must have a value that goes over 25, and the units of months, not years. For the Remaining Debt scale the value needs to be in a range that goes over $8950
Given the sequence below, and that sequence has a domain of n 2 1, find the third
term.
f(n) = 3n+2
Answer:
11Step-by-step explanation:
f(n) = 3n + 2, n ≥ 1
Substitute n = 3:
f(3) = 3(3) + 2 = 9 + 2 = 11
The third term of the sequence is 11 given that that the sequence has a domain of n ≥ 1 and f(n) = 3n + 2. This can be obtained by substituting 3 in the sequence since we have to find the third term.
What is a sequence ?Sequence is an ordered list of terms with a specific order.For example, 3, 7, 11, 15, ...Calculate the third term :
Given that, the sequence ⇒ f(n) = 3n + 2
Since n ≥ 1, first term will be ⇒ f(1) = 3(1) + 2 = 5
Second term will be f(2) = 3(2) + 2 = 8
Third term will be f(3) = 3(3) + 2 = 11
Thus the sequence is 5, 8, 11, ... and the third term is 11.
Hence the third term of the sequence is 11 given that that the sequence has a domain of n ≥ 1 and f(n) = 3n + 2.
