The conversion only gets tricky with the cubed labels. Keep in mind that cm^3 is cm*cm*cm, and that m^3 is m*m*m, AND that there are 100 cm in 1 meter. Here's how the conversion will look if we expand it to make it simple to understand:
. If we do all that multiplying and dividing, and all the crossing out of the labels that cancel, we get
. There you go!
Answer:
is a parabola. The coefficient in front of the highest term (-4 in front of the ) is negative, meaning both of the ends go towards negative infinity (point downward). So, as x approaches positive or negative infinity, y approaches negative infinity.
Applying proportions, it is found that the discounted price of each console at store B is given by:
B. $210.80.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount.
In this problem, at store B, 15 consoles sold for a total of $3,720, hence the price per console is of:
P = 3720/15 = $248.
A discount of 15% is applied, which means that the new price is 85% of the original price, hence:
P = 0.85 x 248 = $210.8.
Which means that option B is correct.

Answer:
x=lengthNEW-lengthOLD
Step-by-step explanation:
The length of the tree used to be only 1.85m. We call this the old length value of the tree, or in short: "lengthOLD"
Next the tree grew to be 5.30m. We call this the new length value of the tree because this measurement was taken later in time, and so after the first measurment. In short: "lengthNEW" is always the newwest value.
To calculate how much the tree has grown, you need to subtract the two lengths. It alway goes in this way:
The newwest number minus the old number.
In this case: x=lengthNEW-lengthOLD
You have to divided 11 by 2 in order to get the radius
And you’ll get 5.5
r=5.5
h=12
Your formula is (1/3)(pi)(r^2)(h)
