Answer:
64 times more paint will be needed since the volume of the second is 64 times the volume of the first
Step-by-step explanation:
If the original sphere is 12 cm diameter
its radius will be half this measure which is 12/2 = 6 cm
The new diameter is 4 times this, so its radius would be 4 times this and it is 24 cm
Now, the volume of the sphere means we have to raise the power of the radius by 3
The other terms in the formula remains the same for both, so we are simply comparing the radii
so we will have the difference in volume in times of multiples as ;
(24/6)^3 = 4 * 4 * 4 = 64
Answer: 735
Step-by-step explanation:
Number of Plates
To find the number of radishes, first find the number of plates.
There are 21 tables with 5 plates per table so
P = 21 tables * 5 = 105 plates
Number of Radishes
Then find the number of radishes
There are 105 plates with 7 radishes per plate so
R = 105 plates * 7 = 735 radishes
Final Answer
735 radishes
Answer:
A) (16-9) =(4+3)(4-3)
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Given the number = 7
The difference of two numbers are 16-9 =7
The difference of squares
4² - 3² = 7
We will use formula
a² - b² = (a-b) (a+b)
4² - 3² = (4 -3) (4+3)
16 -9 = (4 -3) (4+3)
<u><em>Final answer:-</em></u>
<em> The number 7 can be rewritten with the difference of squares identity</em>
16 -9 = (4 -3) (4+3)
