The temperature conversion from Celsius to Fahrenheit is calculated using the following formula: Fahrenheit = (Celsius x 1.8) + 32. Increasing the Celsius temperature by 1 degree will result in an increase of 1.8 degrees Fahrenheit.
To convert a temperature of 36 degrees Celsius to Fahrenheit, we first multiply 36 by 1.8 to get 64.8, then add 32 to that result to get 96.8 degrees Fahrenheit. In other words, 36 degrees Celsius is equal to 96.8 degrees Fahrenheit. To better understand this conversion, it helps to remember that 0 degrees Celsius is equivalent to 32 degrees Fahrenheit. The two scales are offset by 32 degrees, meaning that for every degree Celsius, the equivalent Fahrenheit temperature is 1.8 degrees higher. For example, 10 degrees Celsius is equivalent to 50 degrees Fahrenheit (10 x 1.8 = 18 + 32 = 50). Thus, increasing the Celsius temperature by 1 degree will result in an increase of 1.8 degrees Fahrenheit.

what is the value of 5(2 x -4) - 2y if x = -2 and y =6
Answer:
-52
Step-by-step explanation:
If x = -2 and y = 6, then we can substitute those values into the expression:
5(2 x - 4) - 2y = 5(2(-2) - 4) - 2(6)
= 5(-4 - 4) - 2(6)
= 5(-8) - 2(6)
= -40 - 12
= -52
So, the value of the expression 5(2 x - 4) - 2y when x = -2 and y = 6 is -52.

Two rival dry cleaners both advertise their prices. Store A's prices are modeled by the expression 25x-9 where x is the number of items brought in. Store B's prices are modeled by the expression 5(5x+8), where x is the number of items brought in. When do the two stores charge the same rate? Write the equation and show the work to justify your response.
Answer: never
Step-by-step explanation:
Store A's prices are represented by the expression 25x-9
Store B's prices are represented by the expression 5(5x+8)
To find when the 2 stores charge the same rate , we set the expression equal and solve for x
25x-9 = 5(5x+8)
25x -9 = 25x + 40
Subtract 25x on both sides
-9 = 40
We cannot solve for x
So , the price of two stores never be same

Una mujer de negocios desea invertir $30,000 en fondos diferentes que producen ganancias anuales del
13% y 15% respectivamente.
¿Cuánto debe invertir en cada fondo para obtener ganancias de $4,350 después de un año?
The businesswoman must invest $7,500 in the 13% fund and $22,500 in the 15% fund to earn a return of $4,350 after one year.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
We can use substitution or elimination method to solve when there are more than one equation.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
Let's denote,
The amount invested in the 13% fund = x
The amount invested in the 15% fund = y.
Now,
The total amount invested = $30,000,
i.e
x + y = 30000 _____(1)
The total return after one year = $4,350.
Which can be expressed as,
0.13x + 0.15y = 4350 _____(2)
Use the substitution method.
From (1),
x + y = 30000
y = 30000 - x _____(3)
Substituting y in (2)
0.13x + 0.15(30000 - x) = 4350
Solving for x.
0.13x + 4500 - 0.15x = 4350
-0.02x = -150
x = 7500
And,
y = 30000 - x
y = 30000 - 7500
y = 22500
Thus,
The businesswoman must invest $7,500 in the 13% fund and $22,500 in the 15% fund to earn a return of $4,350 after one year.

A triangle has sides with lengths of 32 millimeters, 60 millimeters, and 64 millimeters. Is it a right triangle?
Answer:
Yes it is a right triangle
Step-by-step explanation:
These side lengths correspond to a Pythagorean triple, specifically 8-15-17, which is a set of three positive integers that satisfies the Pythagorean theorem. The theorem states that in a right triangle, the sum of the squares of the lengths of the two shorter sides is equal to the square of the length of the longest side, also known as the hypotenuse.
In this triangle, 32^2 + 60^2 = 8^2 + 15^2 = 17^2, which confirms that it is indeed a right triangle.
7. Mr. and Mrs. Quigley just moved into a new home with a lot of land. They need to plant grass seed The problem is that they are not sure how to figure the new amount that they need. At their old house they knew that the lawn was 10 ft by 20 ft. and needed 5 pounds of seed. Their new lawn is 100 # by 50 ft. How will knowing the amount of seed needed from their old house help them with Buying seed for the new lawn? How much will they need? Show all work
Answer: Seed needed for the new lawn = 125 pounds
Step-by-step explanation:
Knowing the amount of seed needed for their old lawn will help Mr. and Mrs. Quigley calculate the amount of seed needed for their new lawn based on the size of the area.
First, let's calculate the area of the old lawn:
Area = length × width
Area = 10 ft × 20 ft
Area = 200 square feet
Next, we can determine the seed requirement per square foot for the old lawn:
Seed requirement per square foot = total seed needed ÷ area of the lawn
Seed requirement per square foot = 5 pounds ÷ 200 square feet
Seed requirement per square foot = 0.025 pounds per square foot
Now, let's calculate the area of the new lawn:
Area = length × width
Area = 100 ft × 50 ft
Area = 5000 square feet
To find the amount of seed needed for the new lawn, we can multiply the seed requirement per square foot by the area of the new lawn:
Seed needed for the new lawn = Seed requirement per square foot × area of the new lawn
Seed needed for the new lawn = 0.025 pounds per square foot × 5000 square feet
Therefore, Mr. and Mrs. Quigley will need 125 pounds of grass seed for their new lawn based on the calculations using the information from their old lawn.
Julieta has 58 m of fencing to build a four-sided fence around a rectangular plot of land. The area of the land is 204 square meters. Solve for the dimensions (length and width) of the field.
The dimensions of the field are length is 12 m and width is 17m or length is 17m and width is 17m.
What is Area of Rectangle?The area of Rectangle is length times of width.
Given that Julieta has 58 m of fencing to build a four-sided fence around a rectangular plot of land.
2(L+W)=58
2L+2W=58
Now area of the land is 204 square meters.
LW=204
L=204/W
Now plug in this L in above equation.
2(204/W)+2W=58
408/W+2W=58
2W²+408-58W=0
2(W²-29W+204)=0
(W-17)(W-12)=0
W=17
Now plug in W as 17 in L
L=204/17=12
Hence, the dimensions of the field are length is 12 m and width is 17m or length is 17m and width is 17m.

Answer:
lower right option
Step-by-step explanation:
using the properties of logarithms
• loga + logb ⇔ log(ab)
• loga - logb ⇔ log ([tex]\frac{a}{b}[/tex] )
• log[tex]x^{n}[/tex] = nlogx
• lne = 1
given
a[tex]e^{bt}[/tex] = c ( take ln of both sides )
ln a[tex]e^{bt}[/tex] = lnc
lna + ln[tex]e^{bt}[/tex] = lnc
lna + bt lne = lnc ( subtract lna from both sides )
bt = lnc - lna
bt = ln ([tex]\frac{c}{a}[/tex] ) ← divide both sides by b
t = [tex]\frac{ln(\frac{c}{a}) }{b}[/tex]
The items a to e that follow show the number of sides of a regular polygon. For each item, find the sum and the individual value of the interior angles.
a) 15 sides
b) 20 sides
c) 3 sides
d) 4 sides
e) 100 sides
For the polygon the individual value of the interior angles.
a) 15 sides is 145°
b) 20 sides is 108°
c) 3 sides is 60°
d) 4 sides is 90°
e) 100 sides is 18°
A regular polygon is one where all sides are the same length and all interior angles are the same. The number of sides of a regular polygon can affect the value of its interior angles.
a) 15 sides: The sum of the interior angles of a regular polygon with 15 sides is equal to 2180 degrees. To find the individual value of each angle, divide the sum by the number of sides. In this case,
=> 2180 / 15 = 145 degrees per angle.
b) 20 sides: The sum of the interior angles of a regular polygon with 20 sides is equal to 2160 degrees. To find the individual value of each angle, divide the sum by the number of sides. In this case,
=> 2160 / 20 = 108 degrees per angle.
c) 3 sides: The sum of the interior angles of a regular polygon with 3 sides is equal to 180 degrees. To find the individual value of each angle, divide the sum by the number of sides. In this case,
=> 180 / 3 = 60 degrees per angle.
d) 4 sides: The sum of the interior angles of a regular polygon with 4 sides is equal to 360 degrees. To find the individual value of each angle, divide the sum by the number of sides. In this case,
=> 360 / 4 = 90 degrees per angle.
e) 100 sides: The sum of the interior angles of a regular polygon with 100 sides is equal to 1800 degrees. To find the individual value of each angle, divide the sum by the number of sides. In this case,
=> 1800 / 100 = 18 degrees per angle.

Which of the following is the appropriate measure of variability for the data, and what is its value?
The IQR is the best measure of variability, and it equals 17.
The range is the best measure of variability, and it equals 4.
The IQR is the best measure of variability, and it equals 4.
The range is the best measure of variability, and it equals 17.
The correct option is C. The IQR is the best measure of variability, and it equals 4.
What is IQR (interquartile range)?The IQR (interquartile range), a measure of variability that depicts the range of the middle 50% of the data, is used in box plots. It is determined as the gap between the first and third quartiles (Q1 and Q3) (Q1). Since the box in this instance spans the numbers 17 to 21 on the number line, Q1 equals 17 and Q3 equals 21. IQR = Q3 - Q1 = 21 - 17 = 4 as a result.
The difference between the dataset's maximum and minimum values is represented by the range, another measure of variability. As a result of its sensitivity to extreme values, it is less reliable than the IQR. Although the range in this instance is equal to 27 - 10 = 17, it could not correctly reflect the variety of the data.
Therefore, the IQR is the most appropriate measure of variability for this data, and its value is 4.
