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 + 0.42w; $1.85
0.42 + 0.17w; $1.10
0.17 + 0.42w; $2.36
0.42 + 0.17w; $2.36
Answers
the cost of mailing a four ounces letter is $1.10
step by step explanation:
first, you have a fixed cost, independent of any other variable, which is: 0.42.
then you have a cost that is independent on the weight. expressed the ounces, which is: 0.17 per ounce. that means if you have 2 ounces then your cost would be duplicated, becoming 0.34 and so on forth, let’s define the weight as w.
the total cost of mailing a letter equals the base charge or the fixed cost. plus the cost of the number of ounces that our letter weighs.
we can express this statement in a mathematics terms:
0.42 + ( 0.17 * w) = COST
now, we want to know how much it would cost us to mail a letter that weighs 4 ounces. that means we know the value of the “w” in our expression, so we can substitute it and solve the expression:
0.42 + (0.17 * 4 ) = COST
0.42 + 0.68 = COST
1.1 = COST
it would cost us $1.10 to send a 4 ounces letter :)

Write blue, red, or orange in each section of the circle graph based on the following data:
There are 32 children. 25% of the children like blue, 16 children like red, and 8 children like orange.
Answers
25% of the children like blue, so 0.25*32 = 8 like blue. This is the same number of people who like orange.
So you'll have "blue" in one quarter slice and "orange" in another quarter slice.
So far, we've counted 8 blue + 8 orange = 16 total. Because there are 32 kids overall, this leaves 32-16 = 16 left. This matches up with the fact that 16 like red. This is half of 32, meaning we'll shade two quarter slices to indicate red. Put another way, you'll have "red" in two slices.
Check out the diagram below. That's one possible configuration (other combos are possible).
Ok so 25% like blue, so if we had to make an equation it would be 0.25 x 32 because that would give us the number of children who like blue. So, when we do that we get 8 which is the same amount of kids who like orange. So, 1/4 of that circle would be blue and another one fourth of the circle would be orange. So now we have to look at the red. It says "16 children like red" and we know that theres a total of 32 kids. So, since 1/2 of the circle was of the kids who like blue and orange, the other half has to show the amount of kids who just like red. Look at screenshot below to help.

determine whether WX and YZ are perpendicular,or, neither W(-7,6),X(-6,9)Y(6,3),Z(3,-6)
Answers
Answer: The lines WX and YZ are parallel.
Step-by-step explanation: We are given to check whether the lines WX and YZ are parallel, perpendicular or neither if the co-ordinates of the endpoints of both the lines are
W(3,4), X(5,7), Y(8,2) and Z(6,-1).
We know that the slope of a straight line passing through the points (a, b) and (c, d) is given by
m = d-b/c-a
So, the slope of the line WX is
m1 = 7-4/5-3 = 3/2
and the slope of line YZ is
m2 = -1-2/6-8 = -3/-2 = 3/2
Since , we get m1 = m2, so the two lines WX and YZ are parallel.
Thus, the lines WX and YZ are parallel.
They are not perpendicular, so if you mistyped something and it was parallel that would be the answer, or the answer is neither the mysterious angle form or perpendicular. Hope this helps.

Answers
Answer:
Slope is 50x (50/1)
Explanation:
let m = slope
m = (y2-y1)/(x2-x)

Using an exponential function, we have that:
a) In 10 years, the amount needed will be of $1,219 per week.
b) In 20 years, the amount needed will be of $1,486 per week.
c) In 30 years, the amount needed will be of $1,811 per week.
An increasing exponential function has the following format:
[tex]A(t) = A(0)(1 + r)^t[/tex]
In which:
A(0) is the initial value.r is the rate of change, as a decimal.In this problem:
Currently requires $1000, thus [tex]A(0) = 1000[/tex].Inflation of 2% per year, thus [tex]r = 0.02[/tex]Then, his weekly amount needed is going to be given by:
[tex]A(t) = A(0)(1 + r)^t[/tex]
[tex]A(t) = 1000(1 + 0.02)^t[/tex]
[tex]A(t) = 1000(1.02)^t[/tex]
Item a:
In 10 years, we have that:
[tex]A(10) = 1000(1.02)^{10} = 1219[/tex]
In 10 years, the amount needed will be of $1,219 per week.
Item b:
In 20 years, we have that:
[tex]A(20) = 1000(1.02)^{20} = 1486[/tex]
In 20 years, the amount needed will be of $1,486 per week.
Item c:
In 30 years, we have that:
[tex]A(30) = 1000(1.02)^{30} = 1811[/tex]
In 30 years, the amount needed will be of $1,811 per week.
