20 cm i think
I am not sure but my thinking is
The rectangle becomes 2 30 60 90 triangles and 10 would be the short side making it 20 because the short side is a and the hypotenuse is 2s.

In other words, if a rectangle is 10 cm by 15 cm, what is the length of the diagonal?  Use the Pythagorean Theorem.  a^2+b^2=c^2, where c is the measure of the hypotenuse.

What is the percent error of 7cm
antoniya [11.8K]
The answer is 7.14% 

Your ruler measuring centimeters has lines for each centimeter. The rule for error is anything between 6.5 and 7.5 is considered 7cm. So the degree of error is plus or minus .5cm. 
Your aim is 7cm so you divide your error of .5 by your target measurement. .5/7= 7.14 percent.

Will the standard form 3.2 × 10–4 be more or less than 1? Explain what effect the negative exponent has. Thanks! =)
laila [671]
3.2 * 10^-4 = 0.00032
So the number is less than 1.

The effect the negative exponent has is.....well...here's an example

if the exponent was a positive it would be 3.2 *10^4 = 32,000

If it was positive you would move the decimal point to the right (for this equation) 4 times... if it was negative you would move it the other way.
