Answer:
Density of material would be 4.09 
units is 
Step-by-step explanation:
Given: The mass of a material is 45 grams and the volume of the material is 11 cubic centimeter
Density is defined as mass per unit volume.
It is given by:
where p is the density , m is the mass and V is the volume of the material respectively.
Here, Density is expressed in grams per centimeter cubed (g/cubic cm)
Here, m = 45 g , V = 11 cubic cm
We get;
= 4.09 
therefore, density of a material would be, 
and its units is 
Make it a fraction
7/25 * 4/4 = 28/100
0.28 = 28 percent
There is a 28 percent chance the next marble will be red

Step-by-step explanation:
Answer:
The number of hot dogs sold was 35 and the number of sodas sold was 52
Step-by-step explanation:
Let
x ----> the number of hot dogs sold
y ----> the number of sodas sold
we know that
----> equation A
----> equation B
Solve the system by substitution
substitute equation A in equation B

solve for y



<em>Find the value of x</em>

therefore
The number of hot dogs sold was 35 and the number of sodas sold was 52
