Answer:
250 small cubes
Step-by-step explanation:
Because the volume of the bigger cube 30000
divided by the volume of the smaller cube 120 is 250
30000/120=250
Well, what I’d do is just see who has the most which is Bill and then for the other question I’d just subtract 7.8 - 7.2 which is equal 6 so the pH is greater by .6
Maximum number of smoothies that Erica can make with the yogurt is 5
<h3><u>Solution:</u></h3>
Given that Eric has 
cups of yogurt to make smoothie
Each smoothie uses 
of a cup of yogurt
To find: maximum number of smoothies that Erica can make with the yogurt
Let 'n' be the number of smoothies that Erica can make with the available yogurt
number of smoothies that Erica can make with the yogurt is calculated by divinding the total available cups of yogurt by cups of yogurt needed for one smoothie
<em><u>Therefore we get:</u></em>
total available cups of yogurt = 
cups of yogurt needed for one smoothie =
Substituting the values in above formula we get,
Thus maximum number of smoothies that Erica can make with the yogurt is 5
Answer:

Step-by-step explanation:
Answer:
10 cm.
Step-by-step explanation:
We'll begin by calculating the area of the small bubble. This can be obtained as follow:
Radius (r) = 5 cm
Area (A) =?
Since the bubble is circular in nature, we shall use the formula for area of circle to determine the area of the bubble. This is illustrated below:
A = πr²
A = π × 5²
A = 25π cm²
Next, we shall determine the total area of the small bubbles. This can be obtained as follow:
Area of 1 bubble = 25π cm²
Therefore,
Area of 4 bubbles = 4 × 25π cm²
Area of 4 bubbles = 100π cm²
Finally, we shall determine the radius of the large bubble. This can be obtained as follow:
Area of large bubble = total area of small bubbles = 100π cm²
Radius (r) =?
A = πr²
100π = πr²
100 = r²
Take the square root of both side
r = √100
r = 10 cm
Thus, the radius of the large bubble is 10 cm
