You already have the rates, what you need to find out now is the unit rates. To do this, you simply take first number (eg.420) to divide by the second number (eg. 7).
a.60 miles per hour
b. 12 customers per day
c. 2.5 meters in 1 pound
d. $1.592 for 1 ound
Answer:
I did the math and checked it im pretty sure this is the right answer
Answer:
with the video game cost of x = $6
This agrees with the last option in the list of possible answers
Step-by-step explanation:
Recall that the maximum of a parabola resides at its vertex. So let's find the x and y position of that vertex, by using first the fact that the x value of the vertex of a parabola of general form:
is given by:
In our case, the quadratic expression that generates the parabola is:
then the x-position of its vertex is:
This is the price of the video game that produces the maximum profit (x = $6). Now let's find the y-position of the vertex using the actual equation for this value of x:
This value is the highest weekly profit (y = $246).
Now, recall that we can write the equation of the parabola in what is called "vertex form" using the actual values of the vertex position :
Therefore the answer is:
with the video game cost of x = $6
Answer:
$23.75
Step-by-step explanation:
Ok, first, To solve the problem, we need the amount of square feet of each kite.
To calculate area of triangles, you multiply base with height, then divide by two. (bh/2)
Jake's kite is 5.5 feet long, and 6 feet tall, so we plug this into the equation to get: (5.5 · 6)/2
we simplify to get 33/2 = 16.5 square feet.
Then to get the total cost, we multiply 16.5 with 2.50 to get $41.25, which is the cost of Jake's kite.
Now, we do the same with Rob's kite. (3.5*4)/2 = 14/2 = 7, then multiply by 2.5 to get 7 * 2.5 = $17.5, and that's the cost of Rob's kite.
To get the final answer, we subtract 41.25 to 17.5, which is $23.75
