It cost marci 33 cents to mail a postcard and 49 cents to mail a letter. she sent either a postcard or a letter to each of 28 people and spent $13.08. let x represent the number of postcards she wrote and write an algebraic expression for each item in parts a through c.
Answers
Answer:
24 Letters and 4 Postcards
Step-by-step explanation:
We have to set up a system of equations, since we have two unknown variables. Lets say postcards is the variable "x" and letters is the variable "y".
Our first equation will be the money spent: 0.33x + 0.49y = 13.08, this comes from knowing that it costs 0.33 dollars to mail a postcard and 0.49 dollars to send a letter.
The second equation is the total sent: x + y =28.
Now we need to solve for a single variable, let's do y (or letters). If we subtract y from both sides we get: x = 28 - y.
We can plug that into our first equatino to get: 0.33(28 - y) + 0.49y = 13.08.
If we multiply things out we get: 9.24 - 0.33y + 0.49y = 13.08, and now we have like terms. 9.24 + 0.16y = 13.08.
Subtract 9.24 from both sides to get: 0.16y = 3.84
Divide both sides by 0.16 to get: y = 24.
Now we can plug this into x + y = 28 to see that x= 4.
You could make sure this is correct by solving for x instead of y and do the same process.
Hope this helps.

A 50 ml IVPB bag of ampicillin 500 mg in normal saline is to be run in over 20 minutes. What is the infusion rate in ml/hr?
Answers
Using proportions, it is found that the infusion rate is of 150 ml/hr.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, 50 ml are administered over 20 minutes. How much is administered over one hour = 60 minutes? The rule of three is:
50 ml - 20 min
x ml - 60 min
Applying cross multiplication:
x = 50(60)/20
x = 50(3)
x = 150.
The infusion rate is of 150 ml/hr.

A soccer stadium had a capacity of 25000 seats, but with the new area built this increased by 20%.
Calculate the number of people in the stadium if on a match only 65% of the seats are occupied.
Answers
Answer:
19,500 people
Step-by-step explanation:
20% of 25,000 is 5,000.
Add 5,000 to 25,000 - this will give you 30,000. That is a 20% increase.
65% of 30,000 is 19,500, thus there are 19,500 people in the stadium.

Step-by-step explanation:
To find A you have to divide 3/5 by 4 so that would not work.
To find B you have to subtract 1/4 from 3/5 and that doesn't match the problem.
To find C you do divide 3/5 by 1/4 which matches the problem.
And lastly for D you would divide 1/4 by 3/5 which is the opposite of what the question is asking for.

correct me if im wrong
Two angles say x and y, are said to be complementary iff the sum of both angles x and y is 90° , while on the another hand, if their sum is 180°, they're called supplementary angles. So, here 75° + 105° = 180°, so both the angles are supplementary.
Hence, the required answer is supplementary

Use a diagram to show that (3x+1)(x+2) is equivalent to 3x2+7x+2.
Answers
3x*2 = 6x
x*1 = x
1*2 = 2
that's basically the FOIL method, multiply first terms, the x terms
then the outside terms, the the inside terms, then the constant (last) terms
F=first, O=outside, I = Inside, L = last
add them up to get 3x^2 +6x +x + 2 = 3x^2 +7x +2
(3x+1)(x+2) = 3x^2 +7x+2
draw a rectangle with one side as 3x+1, the other side as x+2. The area of the rectangle is their product
divide the rectangle into 4 smaller rectangles. with sides 3x by x, 3x by 2, x by 1 and 2 by 1
calculate the areas of each rectangle the sum them.
standard form is
y=ax^2 +bx + c or
f(x) = x^2 +7x +2 where a=1, b=7, c=2
another standard form is to put the quadratic equation in vertex form
by completing the square
f(x) or y = x^2 +7x + 49/4 = -2 + 49/4
y = (x+3/2)^2 = 41/4
where the vertex = (3/2,41/4)
standard equation in vertex form is
y= a(x-h)^2 + k where (h,k) = vertex = (3/2,41/4) with a=1
It's an upward opening parabola with y intercept = 41/4 = 10 1/4, axis of symmetry x=3/2

Find the measure of the missing angle
Answers
Answer:
g=118 degrees h=62 degrees
Step-by-step explanation:
So we can use some angle rules that I forget the name of to solve this.
Let's look at angle g first. We know that the opposite angle is 118 degrees. So that also means that g is going to be 118 degrees.
Since g is 118 degrees we can find h. The angle of a line is 180 degrees. This means that we can do 180-118 to find h. h=62 degrees.
We can do the same thing for k and m. Try doing what I did for g and h for those two. Comment if you need help.
