Density is measured in units of mass per units of volume. It can be thought of as a unit rate. The mass of a block of aluminum is 9.45 grams. The volume is 3.5 cubic centimeters (cm³).
What is the density of aluminum?
Answers
Answer:
you answer will be 2.7
Step-by-step explanation:
you just have to divide the 9.45 to 3.5 and you got your answer
The density of the aluminum will be 2700 kilograms per cubic meter.
What is the density?The number of molecules per unit volume is known as density. The SI unit of the density is kilograms per meter cube. The density is a scalar quantity. More density means more the number of molecules present in a unit volume. Then the density is given as,
Density = Mass / Volume
A chunk of metal weighs 9.45 grams. 3.5 cubic centimeters is the volume.
Then the density of the aluminum is given as,
D = 9.45 / 3.5
D = 2.7 grams per cubic cm
D = 2700 kilograms per cubic meter
The density of the aluminum will be 2700 kilograms per cubic meter.
More about the density link is given below.

here is an inequality: 2x+5>50. explain the steps you would use to solve the inequality for x. what would the graph look like
Answers
Answer:
Step-by-step explanation: 2 plus 5
7 <50
Answer:
x = 22.5
Step-by-step explanation:
2x + 5 > 50.
We do inverse operations sooo:
2x + 5 - 5 > 50 - 5.
50 - 5 = 45.
Then we do 2x ÷ 2 and 45 ÷ 2.
45 ÷ 2 = 22.5.
To check our answer to see if its right we do 22.5 x 2 which equals 45. Then we do 45 + 5 which equals 50. So the sign is wrong it should be greater than or equal to.

Answers
Answer:
0; (0, 0); 144; (3, 144)
Step-by-step explanation:
Y = distance (m)
X = time (hr)
X = 48x
If a car travels for 0 hours, it will travel __ mile(s).
y = 48x
Plug in 0 hours for x (time in hours)
y = 48(0)
Any number mutliplied by 0 equals 0
y = 0
If a car travels for 0 hours, it will travel 0 miles. This means it will pass through the point (0, 0).
(0, 0) limits our options to graphs B and D
Car travels 144 miles in 3 hours
To find how many miles it travels in 1 hour, divide 144 miles by 3 hours
144 ÷ 3 = 48
In 1 hour, a car travels 48 miles
If 48 × 3 = 144, then 48 × 4 = ?
48 × 4 = 192
When looking at graph D, there are 4 lines above 0
Counting by 48, it perfectly fits 192 by the fourth line
From (0, 0), if we move 3 units to the right we can find the third vertical line intersecting
Since the lines are counted by 48 and we are looking at the third line: 48 × 3 = 144
Use the slope to move 3 units to the right of the origin and 144 unit(s) up to the find the point (3, 144) that can be used to graph the relationship

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
The number of signs that are placed along the path, assuming that there is a sign at the beginning of the path but not at the end is 2 signs.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Length of the path = 34 mile
There is a sign after every 18 miles.
Now,
There is a sign at the beginning of the path and not at the end.
The number of signs:
= 34 ÷ 18
= 34/18
= 1.8
This means there will be one sign.
Now,
There was a sign at the beginning so we have,
1 + 1 = 2 signs
Thus,
The number of signs that are placed along the path, assuming that there is a sign at the beginning of the path but not at the end is 2 signs.
