Distance of Sun and Mercury = <span>58,000,000 km.
In Scientific notation, it would be: 5.8 </span>× 10⁷ Km
Diameter of a human hair = 0.0025 cm
In scientific notation, it would be: 2.5 × 10⁻³ cm
Before Comparison, we need to bring cms to Kms or vice-versa, so we can easily calculate then, here, we will go from cm to Km.
2.5 × 10⁻³ × 10⁻⁵ Km = 2.5 × 10⁻⁸
Now, we can compare the values,
5.8 × 10⁷ Km > 2.5 × 10⁻⁸
[ reason. - power of smaller number is in negative, it means, it is denominator, which would be very small as compared to other ]
Hope this helps!
V cylinder = A_base * height, A_base = pi*r^2, if height=radius+7, then
V = pi*r^2(r+7)
That's it
Answer:
1260
Step-by-step explanation:
Since we have to predict, we can use ratios to help us solve this.
12 said yes out of 72 randomly chosen, SO,
if 210 would say yes (goes to play), how many is total??
12 is to 72 AS 210 is to HOW MUCH (let it be x)??
<em>We can setup ratio, cross multiply, and solve for x:</em>

Answer:
Try to understand by substitute a number in a and n.
Step-by-step explanation:
For example,
a=2, n=1
a^n= 2^1= 2
= 0.5
2^(-1)=0.5
