The cost to mail a letter is a base charge of $0.42 plus $0.17 for each ounce. Write an expression to represent the cost for mailing a letter that is w ounces. Then find the cost for mailing a letter that is four ounces.
0.17 + 0.42 w; $1.85
0.17 + 0.42 w; $2.36
0.42 + 0.17 w; $1.10
0.42 + 0.17 w; $2.36
Answers
Answer:
0.42+ 0.17w); 1.10$
It would cost us $1.10 to send a 4-ounce letter.
Answer:
C) 0.42 + 0.17 | w: $1.10
Step-by-step explanation:
Note that amount of ounces is denoted by the variable "w". The cost per ounce is $0.17, while the constant charge (charge doesn't change per ounce) is $0.42.
Set the equation:
(Cost per ounce x Amount of ounces) + Constant charge = Total charge:
(0.17x) + 0.42 = Total Charge
Total Charge = 0.17x + 0.42
Next, you are solving for the cost of 4 ounces. Plug in 4 in the variable, x.
Total Charge = 0.17x + 0.42
Plug in 4 for x.
= 0.17(4) + 0.42
Follow PEMDAS, First, multiply, then add:
= (0.17 * 4) + 0.42
= 0.68 + 0.42
= 1.10
~
C) 0.42 + 0.17 | w: $1.10 is your answer.

w-4/h-4=4/3 can someone please answer this its for homework someone told me it was 8 but i got 12
Answers
the letter "w" represents a variable, and the letter "h" also represents a variable. The goal is to solve for either "w" or "h" by using the given information and the rules of algebra.
To solve this equation, we can start by multiplying both sides of the equation by 3 to eliminate the fraction on the right side:
w-4/h-4=4/3
3(w-4/h-4)=3(4/3)
This simplifies to:
3w-12/3h-12=4
Next, we can simplify the expression on the left side of the equation by combining like terms:
3w-12/3h-12=4
3w-3h=-8
Finally, we can solve for either "w" or "h" by using the given information and the rules of algebra. For example, we can solve for "w" by adding 3h to both sides of the equation:
3w-3h=-8
3w=-8+3h
w=-2+h
This means that the value of "w" is equal to the value of "h" minus 2. Alternatively, we could solve for "h" by adding 3w to both sides of the equation:
3w-3h=-8
-3h=-8+3w
h=2-w/3
This means that the value of "h" is equal to 2 minus the value of "w" divided by 3.

Answer:
y=2x+10
Step-by-step explanation:
Perpendicular lines are lines that intersect at a 90 degree angle. Therefore, their slopes are the opposite sign and the reciprocal. The opposite reciprocal of -1/2 is 2. Then you just repeat the same process above to find the equation. m=2, x=-4, and y=2, so plugging in you would get 2 = (2)(-4)+b. Simplifying you get b=10 and so your equation for the perpendicular line that passes through (-4,2) is y=2x+10

Because the triangles are congruent, their angles and sides are of equal degrees and length. Therefore you can set them equal to each other and solve. First, lets look at the angle because there is only 1 variable in it and so it is solvable. For the equation 20 = 3x - 8, x = 28/3. The second equation, 1/4x+y = 14.7 (which is found by setting the sides equal to each other), You can plug in 28/3 for x making the equation 28/12+y=14.7. Which makes y = 371/30.

Answer: Remove, Multiply, Add (RMA)
Step-by-step explanation:
I'll share a method I use. it is removed, multiply, and add. first, you have to remove the decimals from the problem, multiply them, and add the decimals back into the problem. count the number of how many numbers are behind the decimal. for example, let's take 3. after you multiply, count three spaces to the left and place the decimal. let's take 3.12 x 2.7. first, remove the decimals. after you do that, you're left with 312 x 27. do the multiplication, and then count the number of how many numbers are behind the decimals. so, that would be three. your answer for the mutiplication problem is 8,424. since there are three spaces, you would count one, two three. to the left of 8,424. therefore, the answer is 8.424

Answers
Answer:
hello
Step-by-step explanation:
The required probability that William worked on last year was an anniversary party is 1/ 36.
As mentioned in the quesiton,
William is a very busy professional DJ. Last year, he worked at 10-anniversary parties and 26 other events.
Probability can be defined as the ratio of favorable outcomes to the total number of events.
Here,
Total sample space = 26 + 10 = 36
Number of favorable outcomes = 1
the probability that William worked on last year is was an anniversary party,
= Favorable outcome/sample space
= 1 / 36
Thus, the required probability that William worked last year is 1/ 36.

Answers
Answer:
Step-by-step explanation:
You add 3/5 to -4/7 by finding the least common denominator (the bottom part of the fraction).
LCD is found by listing the multiples of the denominators and finding the common one.
5: 5, 10, 15, 20, 25, 30, 35
7: 7, 14, 21, 28, 35
For 3/5 you would multiply the numerator (the top part of the fraction) and denominator by 7, getting 21/35.
For -4/7, you would multiply the numerator and denominator by 5, getting -20/35.
21 + (-20) = 21 - 20 = 1
1/35
The final answer is that n is less than or equal to 1/35.
