Use the distributive property to write an equivalent expression 6(2r-10s+2)
Answer: 12r-60s+12
Step-by-step explanation:
when distributing multiply what is outside the parenthesis * the inside numbers one by one.
6 * 2r = 12r
6 * -10s = -60s
6 * 2 = 12
Now put it all together
12r-60s+12

Lindy is going to New England to visit her brother for spring break and wants to know what the weather will be like. Her brother is a chemist, so naturally he tells her it is expected to be 272 Kelvin while she is in town. Can you help her find the temperature in °F so she can know if she should pack a jacket or not?
Answer:
29.93° F
____________________
The value of the temperature of 272 Kelvin in Fahrenheit is 29.93° F.
How to Convert Kelvin to Fahrenheit?To convert Kelvin to Fahrenheit, enter the supplied value into the below k to f formula. The following are the procedures for converting k to f (Kelvin to Fahrenheit): °F = (K − 273.15) × 1.8 + 32.
Substitute the given value (in K) in the formula:
Then simplify the expression and find the solution.
Then write the final answer in °F.
To determine the temperature in °F when it is in 272° Kelvin
We need to substitute the value of K as 272 in the K to F formula given above.
⇒ °F = (272 − 273.15) × 1.8 + 32
⇒ °F = -1.15 × 1.8 + 32
⇒ °F = -2.07+ 32
⇒ °F = 29.93°
Therefore, the value of 272 K in Fahrenheit is 29.93° F.

Alexander is in the business of manufacturing phones. He must pay a daily fixed cost to rent the building and equipment, and also pays a cost per phone produced for materials and labor. Let CC represent the total cost, in dollars, of producing pp phones in a given day. A graph of CC is shown below. Write an equation for CC then state the yy-intercept of the graph and determine its interpretation in the context of the problem.
The linear function that defines C is given as follows:
C(x) = 400 + 100x.
The y-intercept of 400 represents that the fixed cost of producing zero phones on a day is of $400.
What is the linear function?The slope-intercept definition of a linear function is given as follows:
y = mx + b.
In which:
m is the slope, representing the change in the output variable y when the input variable x is increased by one.b is the y-intercept, representing the value of the output variable y when the input variable x has a value of zero, meaning that it is the value of y at which the function crosses the y-axis.From the image given at the end of the answer, the values of these parameters are given as follows:
m = 100, b = 400.
The y-intercept of 400 are the operating costs of the company, as they have to be paid even when zero phones are produced, and thus the equation is given as follows:
y = 100x + 400.
Missing InformationThe graph is given by the image shown at the end of the answer.

Which is a valid conclusion using the Law of Syllogism? a) If it is raining when we leave, I will open the umbrella. b) If I open the umbrella, you will see pink ducks. Group of answer choices If I open the umbrella, you will see pink ducks. If it is raining, you will see pink ducks. It is raining. You will see pink ducks.
Answer:
If it is raining when we leave, you will see pink ducks.
Step-by-step explanation:
The Law of Syllogism is defined by the following rule:
[tex]P\implies Q \,\land\,Q\implies R[/tex] (Eq. 1)
[tex]\therefore P\implies R[/tex]
Where [tex]P[/tex], [tex]Q[/tex], [tex]R[/tex] are propositions.
From statements we know that propositions are:
P = It is raining when we leave.
Q = I open the umbrella.
R = You see pink ducks.
By applying the Law of Syllogism we construct this compound proposition:
If it is raining when we leave, you will see pink ducks.

what is an equivalent fraction to -5/25
Answer:
stinkey monkey :3
The equivalent fraction to -5/25 will be -1/5. Since the value of both fractions is the same as a result represented as the equivalent fraction.
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
It is given that the expression is, -5/25.
We have to find the equivalent fraction for the given expression.
Equivalent fractions are two or more fractions that, although having various numerators and denominators, are all the same. 1/5, for instance, is equal to -5/25. The fraction is always expressed in its simplest form, "one-fifth."
Thus, the equivalent fraction to -5/25 will be -1/5. Since the value of both fractions is the same as a result represented as the equivalent fraction.

Alan's goal is to decrease his weight by 5% each month. This month, he weights 280. What weight, in pounds, is he hoping to weigh next month?
Answer:
294lbs
Step-by-step explanation:
You can find the weight by taking 10% of 280. (Move the decimal one spot to the left) That would be 28. Then divide 28 by 2 and you get 14, which would be 5%. Then add 14 to 280 and you get 294.

A certain population of bacteria has an average growth rate of 0.06 bacteria per hour. The formula for the growth of the bacteria's population is = ࡼ (. ૠૡ) where, ࢚. Po is the original population, t is time in hours, and A is the new population . If the current population of a culture was 3000 bacteria (A) and it started growing 30 hours ago, what was the original size of the bacteria (Po)?
Answer:
522 bacteria
Step-by-step explanation:
The formula given as growth rate =
A = Po (1 + r)^t
Where:
Po is the original population
t is time in hours = 30
A is the new population = 3000
r is growth rate = 0.06
3000 = Po × ( 1 + 0.06)^30
3000 = Po × 1.06^30
Divide both sides by 1.06^30
Po = 3000/1.06^30
Po = 522.33039273 bacteria
Approximately = 522 bacteria
The original size of the bacteria was 522 bacteria
900 people attended a football game. If 25% of the people who attended were teenagers, how many teenagers attended the game?
The football game was attended by 225 teenagers out of 900 people who attended the game.
What is the percentage?A percentage is a minimum number or ratio that is measured by a fraction of 100.
The number of teenagers who attended the game can be calculated by finding the percentage of people who were teenagers. The word formula for the calculation as;
Number of teenagers in the game = 900 × 25%
Writing the percentage as fraction;
Number of teenagers in the game = 900 × 25/100

All the angles in a triangle will add up to 180 degrees.
Therefore, subtract all the given angles to find x.
180 - 20 -130 = 30
So the missing angle is 30 degrees.
Intro:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
We should know that the sum of all the angles in the triangle add up to 180. So since we already know two we can add those two and then subtract it from 180 to find the missing angle or I like to write equations...
[tex]20+130+x=180[/tex]
After we make an equation we would combine like terms...
[tex]150+x=180[/tex]
Now all we have to do is subtract 150 on both sides to get our missing angle...
[tex]x=30[/tex]
So the missing angle is 30°.

Mrs. Oliver has a stick that is 5 feet 8 inches. How many inches long is the stick?
Answer: 68
Step-by-step explanation:
if there are 12 inches in a foot and there are 5 feet then that multiplies to 60 inches, simply add the extra 8 and you get 68
Answer:
68 inches.
Step-by-step explanation:
So we know that 1 feet equals to 12 inches.
We just need to multiply 12 by 5 and then plus 8. Which will give us 68.
To do this, we must first put the 8 aside.
Then we multiply, 12x5=60, then we bring back the 8 in.
60+8=68.
So the answer is 68 inches
