Answer:
<h3>(A)</h3>
The answers will have the same value, beacuse both scientific notations have the same coefficient, 4.2 and 1.4. Also, if you mentally subtract the exponents of those powers, you would have the same exponent. So, equal coefficient and equal exponent will give the same result.
<h3>(B)</h3>
The value of each expression can be found by dividing coefficients and powers.

<h3>(C)</h3>
The value of each expression in standard form is

Remember that standard form refers to the number without the ten-power.
I'm having the same troubles with this type of geometry sort of.
Answer:
177 balls
Step-by-step explanation:
Let's start with the space we need for each sphere. If we approximate the value of the area to that of a cube that has the same dimensions of the diameter
[tex]V=H*W*D=0.8*0.8*0.8= 0.51 inches3
I can calculate the volume of the box as
[tex]V=H*W*D=3*4*7.5= 90 inches3
Finally I divide the volume of the box between the volume I need for each sphere Vt/Vs= 90/0.51 ≅ 177 balls
Answer:
13 inches
Step-by-step explanation:
10 * 1/4 = 2 1/2 inches
16 * 1/4 = 4 inches
2(2 1/2) + 2(4) = 13 inches
