Is 50 degrees celsius hotter than 50 degrees fahrenheit?
50 degrees Celsius is hotter than 50 degrees Fahrenheit because the Celsius scale rises at a faster rate of 1.8 times the Fahrenheit scale per degree, which measurably shows the greater warmth of 50°C compared to 50
Explanation:Yes, 50 degrees Celsius is hotter than 50 degrees Fahrenheit. To understand why, let's look at how temperature is measured on both scales. On the Celsius scale, the freezing point of water is 0°C and the boiling point is 100°C, whereas on the Fahrenheit scale, the freezing point is 32°F and the boiling point is 212°F. This means that 100 Celsius degrees cover the same range as 180 Fahrenheit degrees.
The rate at which temperature increases per degree is faster on the Celsius scale compared to the Fahrenheit scale. Specifically, each degree on the Celsius scale corresponds to a 1.8 times larger temperature change than one degree on the Fahrenheit scale. Therefore, a temperature of 50°C is significantly warmer than 50°F. so, 50°C is equivalent to 122°F, a fact made evident by the conversion formula: °F = (°C × 9/5) + 32.

The expression 3x^3 + 4x^2 - 15x - 20 can be factored into the form (3x + 4)(x^2 - 5) by grouping terms, factoring out common components, and simplifying.
Explanation:The provided expression to be factored is [tex]3x^3 + 4x^2 - 15x - 20.[/tex]Factoring this involves finding common factors and breaking the terms down until we cannot do so any further.
Group terms that look like they might have common factors: [tex](3x^3 + 4x^2) - (15x + 20).[/tex]Factor out the common factors: [tex]x^2(3x + 4) - 5(3x + 4).[/tex]Notice that we have the binomial of (3x + 4) common between both terms. We can now factor that out: [tex](3x + 4)(x^2 - 5).[/tex]

What is the point slope form of a line with slope 4/5 that contains the points -2,1
Answer:
[tex]y-1= \frac{4}{5} (x+2)[/tex]
Step-by-step explanation:
Using point-slope intercept form:
The equation of line is given by:
[tex]y-y_1 = m(x-x_1)[/tex] .....[1]
where,
m is the slope of the line and [tex](x_1, y_1)[/tex] is the point on the line.
As per the statement:
A line with slope 4/5 that contains the points (-2,1)
⇒m = [tex]\frac{4}{5}[/tex] and [tex](x_1, y_1)=(-2, 1)[/tex]
Substitute these values in [1] we have;
[tex]y-1= \frac{4}{5} (x+2)[/tex]
Therefore, [tex]y-1= \frac{4}{5} (x+2)[/tex] is the point slope form of a line with slope 4/5 that contains the points (-2,1).

One car rental company charges $30 per day plus $0.25 per mile driven. a car company charges $40 per day plus $0.10 per mile driven. how many miles must you drive for a one-day rental at the second company to be less expensive than the same rental at the first company? write an inequality to solve.
Answer:
66.667 miles
Step-by-step explanation:
Given: One car rental company charges $30 per day plus $0.25 per mile driven.
Second car company charges $40 per day plus $0.10 per mile driven.
To find: how many miles must you drive for a one-day rental at the second company to be less expensive than the same rental at the first company?
Solution: Let the distance driven on a day be x miles.
As per question,
The first rental company will charge [tex]=30+0.25x[/tex]
The second rental company will charge [tex]=40+0.10x[/tex]
Now, we want the rental charges of second company to be less expensive then the first.
So we get the inequality,
[tex]30+0.25x>40+0.10x[/tex]
[tex]0.25x-0.10x>40-30[/tex]
[tex]0.15x>10[/tex]
[tex]x>\frac{1000}{15}[/tex]
[tex]x>66.667[/tex] miles
Hence, at least 66.667 miles should be driven on a day.

The median of the values of the data set is h. If 625 were subtracted from each of the values in the data set what would be the median of the resulting data ?
A. H - 625
B.625 - h
C.h + 625
D.625 • h
The correct answer is A. H - 625.
Sure, let's go step by step to find the correct answer.
Given:
- Median of the original data set = h
- Subtracted 625 from each value in the data set
Let's represent the original data set as {x1, x2, x3, ..., xn} where n is the number of values in the data set.
1. Median of the original data set:
The median of a data set is the middle value when the values are arranged in ascending or descending order. Since the data set has been modified by subtracting 625 from each value, the new data set would be {x1 - 625, x2 - 625, ..., xn - 625}.
2. Median of the modified data set:
If we subtract 625 from each value, it doesn't affect the relative order of the values. Therefore, the median of the modified data set would also be h.
So, the correct answer is A. H - 625.
The median represents the middle value in a sorted data set. When we subtract a constant (625 in this case) from each value in the data set, it shifts the entire set downwards without changing the order of values relative to each other. Therefore, the position of the middle value, which determines the median, remains the same. This means the median of the modified data set will still be h.

if an angle is acute then its measure is 30 degrees true or false
An acute angle is any angle less than 90 degrees, and while 30 degrees is an example of an acute angle, it is not accurate to say that all acute angles must be 30 degrees.
Explanation:The statement 'If an angle is acute then its measure is 30 degrees' is false. An acute angle is defined as any angle that is less than 90 degrees. While 30 degrees is indeed an example of an acute angle, an acute angle can be any value less than 90 degrees. For example, 45 degrees, 20 degrees, or 1 degree are also acute angles. Therefore, it is not accurate to say that an acute angle must be 30 degrees.

Classify the function as linear or quadratic and identify the quadratic, linear, and constant terms. f(x) = (3x + 2)(−6x − 3)
A) quadratic function; quadratic term: 6x^2; linear term: 24x; constant term: −6
B) linear function; linear term: −21x; constant term: −6
C) quadratic function; quadratic term: −18x^2; linear term: −21x; constant term: −6
D) linear function; linear term: −18x^2; constant term: −6
Answer:
The correct Option is C). quadratic function; quadratic term: −18x²; linear term: −21x ; constant term: −6
Step-by-step explanation:
Given : f(x) = (3x + 2)(-6x - 3)
Now, f(x) = -18x² -9x -12x - 6
⇒ f(x) = -18x² - 21x - 6
Now, since the highest degree of the given function f(x) is 2 so the function f(x) is quadratic.
Now, quadratic term is one which has highest power x = 2 So, quadratic term = -18x²
Linear term is one which has power x = 1 So, linear term = -21x
Constant term is one which has power of x = 0. So, constant term = -6
Hence, The correct Option is C). quadratic function; quadratic term: −18x²; linear term: −21x ; constant term: −6

By the end of the school year, Terry had passed 80% of his science tests. If Terry failed 4 science tests, how many science tests did Terry pass?
Answer: Terry passed 16 science tests.
Step-by-step explanation: Given that by the end of the school year, Terry had passed 80% of his science tests and Terry failed 4 science tests.
We are to find the number of science tests that Terry passed.
Let x represents the total number of science tests that Terry appeared in.
Since he failed 4 science tests, so the number of science tests that Terry passes is given by
[tex](x-4).[/tex]
Since he passed 80% of his tests, so we get
[tex]80\%\times x=x-4\\\\\\\Rightarrow \dfrac{80}{100}\times x=x-4\\\\\\\Rightarrow \dfrac{4}{5}\times x=x-4\\\\\Rightarrow 4x=5x-20\\\\\Rightarrow 5x-4x=20\\\\\Rightarrow x=20.[/tex]
So, total number of science tests = 20.
Therefore, the number of science tests that Terry passed is given by
[tex]n=20-4=16.[/tex]
Thus, Terry passed 16 science tests.

Option: C is the correct answer.
C.) F(x)= x
Step-by-step explanation:We know that a linear parent function is a function whose graph is a straight line passing through the origin and the equation of such a function is given by:
