Answer:

72 tests

Step-by-step explanation:

lets put this in a ratio

27 (tests) : 3 (hours)

now we simplify by dividing each side by 3

9:1

Now we must find 8 hours so multiply each side by 8

72:8

the teacher will grade 72 tests in 8 hours

Can somebody pls help me!! :(( it’s due today

Answer: $4110.8 (more likely - 95% sure) or $2,107 (less likely)

Step-by-step explanation: It could be $4110.8 because you have the take the total they made and subtract is from the cost of the toys ($7,230-$2,450=$4,780). Then you have to take the result of that and get 14% of it, then subtract that from the $4,780 amount. Then you get the final answer which is $4110.8.

<u />

However, it could also be $2,107 because the question itsn't that clear in the second sentence. It could be saying that $2,450 is the price of the toys (which is what I assumed above), or that it is the profit that the $2,450 (which I used below). I think that the above answer is more likely because if not then the first number would never be used. Anyways here is the second way it could be.

Step-by-step explanation: It could be $2,107 because you take the profit ($2,450) and get 14% of it, then subtract that from the $2,450 amount. Then you get the final answer which is $2,107.

If I was you, I would do the first one ($4110.8) because I really think it is that one. I just put the other one here just in case.

What is 125x^9+64y^12 written as sum of cubes?
vladimir2022 [97]

Answer:

Step-by-step explanation:

125x^9 = (5x^3)^3

64y^12 = (4y^4)^3

If you want that factored it is

(5x^3 + 4y^4)( (5x^3)^2 - 5x^3*4y^4 + (4y^4)^2 )

(5x^3 + 4y^4)( 25x^6 - 20x^3y^4 + 16y^8)

Water has a density of 1.0 g/cm3 a plastic box has a volume of 78 cm and weighs 80 grams will the box sink or float on water
jek_recluse [69]

<u>What we'll do:</u>

A method to find whether an object will float or sink in a liquid is to find it's specific gravity with respect to the liquid, The Specific Gravity tells us the percentage of object's mass which will be submerged in water

<u>Finding the Specific Gravity:</u>

<u>Density of Box:</u>

Density = Mass / Volume

Density = 80 grams / 78 cm³

Density = 1.02 grams/cm³

<u>Specific Gravity of Box with respect to water:</u>

Specific Gravity = Density of Box / Density of Water

we know that density of water is 1 gm/cm³, plugging the values

Specific Gravity = 1.02 / 1

Specific Gravity = 1.02

Hence, 102% of the object will be under water

Q. but I've only heard about 100% of something, how can something be more than 100%?

A. The answer is that the extra 2% over the 100% is providing to the object being even deeper underwater
