Answer:1152 cubic in

v= L×W×H

v= 8×15×12

v= 1440 cubic in ( if the tank is 100% full)

Which of the following mathematical symbols represents "the opposite of"?

asambeis [7]

Answer:

the minus sign

Step-by-step explanation:

In mathematics, the symbol for the additive opposite is the minus sign

The symbol for the multiplicative opposite is the inverse operation 1/x (I think)

So, yes, specific opposites have symbols, BUT...

Just saying "the opposite of" is too blurry to find one word that represents that.

Jan took her brother out to dinner. The cost of Jan’s dinner was $18.50. The cost of her brother’s dinner was $19.00. If they wa

Vikki [24]

The total bill that would be paid by Jan is equal to $43.125.

Given the following data:

Cost of Jan’s dinner = $18.50.

Cost of brother’s dinner = $19.00.

Tip = 15%

To determine the total bill that would be paid by Jan:

First of all, we would calculate the total cost of their dinner as follows:

$Total\;cost = 18.50 + 19.00$

Total cost = $37.50

Next, we would calculate the tip cost for the total cost of their dinner:

$Tip\;cost = \frac{15}{100} \times 37.5\\\\Tip\;cost =0.15\times 37.5$

Tip cost = $5.625

For the total bill:

$Total\;bill = Total\;cost + Tip\;cost\\\\Total\;bill = 37.5 + 5.625$

Total bill = $43.125.

A college football coach wants to know if there is a correlation between his players’ leg strength and the speed at which they c

Leto [7]

Answer:

Please Read below! As a professional athlete, I think I can help. :)

Step-by-step explanation:

First, what is correlation? Correlation is when there is a mutual relationship or connection between two separate things. More studying, better grades. Less sleep, worse focus. In this instance, the football coach wants to see if better leg strength means a faster 40 yard sprint!

As a professional athlete, I can answer immediately that stronger legs, does generally mean a faster sprint. However, this does not mean better endurance in a long distance race!

So the correlation is: stronger legs = faster 40 yard run

A player that can reach 22 leg-presses is likely going to run a faster 40 yard dash, then someone who can only do 10 leg presses. At the same time, however, it's important to take into account the weight of each player, because the person with stronger legs, might have more weight to carry!

I cannot see any chart provided, but I'm going to assume that there is a positive linear graph, with equations being in slope form (y = mx + b).

Let me know if this helps! :)
