1. An object submerged in water, rises up a volume of water equal to the volume of the object. 


2.   1 milliliter of water has a volume of 1 cubic centimeters. 


3.    Mass= Density * Volume
-----------------------------------------------------------------------------------------------------


The water level rises from 20.mL to 41.mL means that a volume of 21mL of water has been displaced.              

This means that the volume of the object is 21 cm cubed.        (by 1 and 2)

By 3, the density of the piece of metal is:

Density=Mass/Volume=140 g / 21 cm^3= (140/21) g/cm^3=6.67 g/cm^3


Answer: 6.67 g/cm^3

<h3>Answer:  18</h3>

==========================================================

Explanation:

2 cm on paper (or on screen) represents 3 meters in real life.

The backyard is 2 cm horizontally across on the screen, so it's 3 meters across in real life. This is the shorter dimension.

The longer dimension is 6 meters. We can think of it like this

2 cm : 3 meters

2*2 cm : 2*3 meters .... multiply both sides by 2

4 cm : 6 meters

The real backyard is 6 meters by 3 meters to give an area of 6*3 = 18 square meters.

Ghella [55]

Answer:

measure of angle A is 80 degree.

Step-by-step explanation:

isosceles triangle will have same base angles

first base angle is 50, and the second will also be 50

3 angles of a triangle will add up to be 180 degree.

A is the vertex angle.

So 50 + 50 + A = 180

100 + A = 180

A = 80.
