On January 22 in 1943, the town of Spearfish, South Dakota, set the record for the world’s fastest temperature change. At 7:30 a.m., the temperature was −4°F. By 7:32 a.m., the temperature was 45°F. By 9:00 a.m. the same day, the temperature was 54°F. By 9:27 a.m., the temperature was −4°F. What is the difference between the temperature at 7:30 and the temperature at 9:27? Make sure to show whether the change was positive or negative.

its 100
Step-by-step explanation:
well since its a parallel line, 7 and 3 are corresponding and that makes 3 also 80. buh then 3 is also adjacent to 2 and that makes it also 80 and since 2 is on the same line as 1 and an angle on a straight line is 180, it automatically makes 1 an angle of 100 as 180 - 80 should give u 100.

Relative minimum: The coldest temperature outside the car was -4°C.
The negative interval is: between the 110th and 170th kilometers, the outside temperature was below zero.
The increasing interval was: over the first 50 km, the temperature outside the car got warmer.
How to Interpret the Quadratic Graph?The relative minimum or maximum of a graph is:
A relative maximum point is a point where the function changes direction from increasing to decreasing (making that point a "peak" in the graph).
A relative minimum point is a point where the function changes direction from decreasing to increasing (making that point a "bottom" in the graph).
Thus, the relative minimum of the graph is -4°C.
The negative interval is between the 110th and 170th kilometers, the outside temperature was below zero.
The increasing interval was over the first 50 km, the temperature outside the car got warmer.

what is the value of x
Answers
Answer:
40
Step-by-step explanation:
Add all of the angles and set them =180
Answer:
x=40
Step-by-step explanation:
We are given all 3 angle equations for the interior angles of a triangle:
x-10
2x-10
2x
We know that all angles inside a triangle must add up to 180 degrees, so let's write an equation:
180=(x-10)+(2x-10)+(2x)
simplify
180=5x-20
add 20 to both sides
200=5x
divide both sides by 5
40=x
So, x=40.

Which expression is equivalent to 12a⁻⁴ b³c⁸/3a⁻² b⁹c⁻²
for all values of a, b, and c where the expression is defined?
Answers
To simplify the expression, we can use the laws of exponents:
12a⁻⁴ b³c⁸ / 3a⁻² b⁹c⁻²
= (12/3) (a⁻⁴ / a⁻²) (b³ / b⁹) (c⁸ / c⁻²)
= 4 (a⁻⁴+2) (b³-9) (c⁸+2)
= 4a⁻² b⁻⁶ c¹⁰
Therefore, the expression is equivalent to 4a⁻² b⁻⁶ c¹⁰ for all values of a, b, and c where the expression is defined.

Explanation:
We have these three rules for scale factors
scale factor > 1, enlarge the image0 < scale factor < 1, shrink the imagescale factor = 1, the preimage and image are identicalWith those rules in mind, we have enlargements for these transformations.
P to QP to RQ to RAll of which represent some scale factor larger than 1. We don't have enough information to pinpoint what that scale factor would be.
In other words, if you go from small to big, then you apply some scale factor larger than 1 to enlarge the image.
----------------
We also have these reductions
Q to SR to PThis is where we go from big to small. The image shrinks and we use some scale factor between 0 and 1.
----------------
And finally we have these transformations in which the size of the image does not change. Therefore the scale factor is 1.
P to SS to PThe order doesn't matter for this subset, but the order will matter for the other batches of transformations.

Considering area (A) of garden as 30 square feet:
30 = x(2x+7)
Now we need to expand it:
x(2x+7) = 2x^2 + 7x
2x^2 + 7x = 30
Adding this into an Algebra calculator gives us 5/2 or 2.5
So x = 2.5
To prove this:
2(2.5) + 7 = 12
14 * 2.5 = 30
(2x+7) x = 30
you can distribute to make this easier
2x^2 + 7x = 30
you can plug this into quadratic formula by setting the equation =0, so:
2x^2 +7x -30 = 0
where 2x^2 = a
7x = b
and -30 = c
you can plug this into your calculator and get an answer of
X = 2.5

It isn't B because the point does not start at 600 and it is not A because it shows the entire decrease of the mass in one millennium. The correct answer is c.
Consider the situations in the table below
Situation A: A hang glider descended 33.57 feet, and then ascended 14.98 feet.
Situation B: A football team gained 7 2/5 yards in one play, and then lost 3/5 of a yard in the next play.
Situation C: A hiker walked 3 1/6 miles yesterday and 2 1/2 miles today.
Situation D: A worker earned $23.66 Monday and spent $15.84 Tuesday.
Calculate the sum of each situation. Order the situations from least to greatest based on the numeric value of the sums.
Answers
Answer:
Step-by-step explanation:Situation A: The hang glider descended 33.57 feet and again ascended 14.98. So 33.57 - 14.98 = 18.58. So now the hang glider is at 18.58 feet
Situation B: Initially they gained 7 2/5 yards and then lost 3/5 yards.
7 2/5 yards can be written as 37/5. As they lost 3/5 yards, 37/5 - 3/5 = 34/5. So the remaining yards are 34/5 yards.
Situation C: Hiker walked 3 1/6 miles and then 2 1/2 miles. So the total distance is 3 1/6 + 2 1/2 = 5 4/6 miles.
Situation D: Total amount earned is $23.66 + $15.84 = $39.5.

x=7 over 3y+5
substitue the x above for x in the equation -2x-7y=5
-2(7 over 3y+5)-7y=5

Answers
Answer:
No
Step-by-step explanation:
Pi (π) is a mathematical constant representing the ratio of a circle's circumference to its diameter. It is an irrational number, which means it cannot be expressed as a finite decimal or a fraction. Therefore, it is not possible to solve for pi in the traditional sense.
However, pi can be approximated to a certain number of decimal places using various mathematical methods, such as the Monte Carlo method or numerical integration. The commonly used approximation for pi is 3.14159265358979323846, but the actual value of pi has an infinite number of decimal places and cannot be fully calculated.
