When you write a number that is less than 1 in scientific notation how does the power of 10 differ from when you write a number greater than 1 in scientific notation?
Answer : In scientific notation all numbers are written in the form m × 10ⁿ. If the number is less than 1, ten is raised to a negative power, so : m × 10⁻ⁿ.
Example : a decimal number less than 1 is 0.02 = 2 x 10⁻² in scientific notation.
Hope this helps!
What’s the the math problem? I don’t see it..
Answer:
C.
Step-by-step explanation:
So there are 20 kids with brown hair and this represents 80% of the class total.
So this means 20=.8n since we don't know the total number of kids.
20=.8n
Divide both sides by .8
25=n
So 25 is the total number of kids.
C. is the answer
You could also setup this equation given that 80% is 80/100:
[tex]\frac{20}{\text{ total }}=\frac{80}{100}
To figure out what that total is there you can divide top and bottom of the fraction on right hand side by 4 which gives you the 20 on top and the 25 on bottom.
The difference between 200 and -150 is 350. 350÷75= 4.666666... but as it is whole weeks it will be 5 weeks
He should use the Pythagorean Theorem to find the missing length.
Since KT is tangent to the circle and TL reaches the center of circle L, the measure of angle LTK is 90 degrees. This means that triangle LTK is a right triangle which means the Pythagorean Theorem can be used.
So,
TL²+(12)²=(13)²
=> TL²+144=169
=> TL²=25
=> TL = 5
Therefore, the radius of circle L is 5 feet.
