3 x 7 because three, seven times is 21
Answer:
7
Step-by-step explanation:
28 ÷ 16 = 1.75
1.75 × 4 = 7
The way I did it is by finding out how much bigger 28 is than 16 by dividing and then I multiplied the answer (1.75) by 4 to get the bigger answer. The problem is showing you that the triangles are the same just different sizes.

Answer:
3.5 * 10^-4 centimeters
Step-by-step explanation:
Here, we have one uranium atom having a diameter of 3.5 * 10^-8 centimeters.
We now want to find the sum of 10,000 uranium atoms diameters
Mathematically;
That would be ;
3.5 * 10^-8 * 10,000
But 10,000 = 10^4
Thus, we have
3.5 * 10^-8 * 10^4
= 3.5 * 10^-4 centimeters
