What is surface area? Question 5 options: The sum of all the areas of all the faces of a 3D object (think: wrapping paper) The measure of space inside a 2D object The measure of space inside a 3D object The measure around a 2D shape (Think: a fence)

chase is right because he already been to the swings and he know how far it will be to get there

step-by-step explanation:

the answer is 21%.

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:

answer: the answer is 100 x 12,500, which is 1,250,000.

step-by-step explanation: emily solved for a part when she should have solved for the whole.  

875,000 should be the numerator of the equivalent ratio.  

70 x 12,500 is 875,000.
