Bob took his family out to lunch. He bought 3 hot dogs and 2 hamburgers for $11. If the guy in front of him bought 2 hot dogs and 4 hamburgers for $16, what is the cost of one hamburger?
Answer:
Hotdog: $1.50
Hamburger: $3.25
Step-by-step explanation:
You write down the 2 equations based off of the information as I did:
Let x = cost of a hotdog
Let y = cost of a hamburger
and so:
3x + 2y = 11
2x + 4y = 16
Now, we need to find x and y:
We will make both equations equal to y to compare them to each other.
2y = 11 - 3x
y = 5.5 - 1.5x
4y = 16 - 2x
y = 4 - 0.5x
4 - 0.5x = 5.5 - 1.5x
x = $1.5
Now plugging in x into the equation:
2(1.5) + 4y = 16
3 + 4y = 16
4y = 13
y = $3.25
And so hotdog = $1.5 and hamburger = $3.25

Yuk noticed that out of 24 students entering the building at Willowville Elementary School this morning, 8 of them were carrying a lunch box. If these students are representative of the entire school, how many of the Willowville's 84 students would you expect to have brought a lunch box?
Answer:
the students that brought a lunch box is 28
Step-by-step explanation:
The computation of the students that brought a lunch box is shown below:
= Entire school students × students that carry a lunch box ÷ entering students
= 84 students × 8 ÷ 24 students
= 28 students
Hence, the students that brought a lunch box is 28
If a value of a car worth 50000 is deprecating half yearly at 10 percent pa the correct expression to express its value after 2 years is?
Answer:
50,000 x 0.90 ^ 4 = X
Step-by-step explanation:
Since the value of a car worth $ 50,000 is deprecating half yearly at 10 percent, the correct expression to express its value after 2 years is determined through the following calculation:
50,000 x 0.90 ^ 4 = X
32.805 = X
Thus, after 2 years with a semi-annual depreciation of 10%, the car will be worth $ 32,805.

Find the area of the figure.
The area is
square units.
Answer:
36 square units
Step-by-step explanation:
split the figure so that it's a triangle and a rectangle. Find the area of the rectangle (base x height or 6 x 4), which is 24 square units. Then, find the area of the triangle ((base x height)/2 or (6 x 4)/2), which would be 12 units. Then add those units up (24 + 12) and you get 36.

In two or more complete sentences compare the number of xintercepts in the graph of f(t)=t^2 to the number of x-intercepts in the graph of g(t)=(t+3)^2
Answer:
f(t)=t^2 rests at (0/0) and grows upwards, so there is only a single x-intercept. g(t)=(t+3)^2 is f moved 3 to the left, so it also only has one intercept but at (-3,0).
