Hello fellow human! I hope this helps and possibly answers your question ♡＼(￣▽￣)／♡ Best of luck!

Rounded to the nearest hundredth: 2.34 g/cm³

Step-by-step explanation:

Here's the formula to find the Density: $p=\frac{m}{v}$

This is what the variables mean:

p = density

m = mass

V = volume

Now let's see what clues you have from this toy spoon!

p = ? We are going to solve to find out!

m = 7.5 grams

V = 3.2 mL

First, we should know that there is only 1 gram in each mL and vise-versa, so there is no need to convert these measurements.

Next, we plug in the values from what we know into the equation.

This is the formula: $p=\frac{m}{v}$

Now if we plug in our values we get: $p=\frac{7.5}{3.2}$

From that we get, p = 2.34375‬

Finally, if we round our answers we get:

Rounded to the nearest hundredth: 2.34 g/cm³

Rounded to the nearest tenth: 2.3 g/cm³

g/cm³ is the unit for density (in grams), so its up to you to put it or not!

Have an amazing day!! (♡°▽°♡) I hope you found this helpful ;))

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

step-by-step explanation: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

$a=9\times 12=108\text {ft^2}$

so the area of the floor is 108 square feet, converting that into square yards we get,

$108 \times 0.1111= 12 \text{yd^2}$

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

$\$15 \times 12=\$180$

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

$a = 12 \times 15=180\text {ft}^2$

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

$180 \times 0.111=20 \text {yd}^2$

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

$\$15 \times 20= \$300$

so, it will cost $300.
