Answer:

$2.17 \times 10^{-1}$

Step-by-step explanation:

$(7 \times 10 ^{-6}) + 0.26 - (5 \times 10^{-2}) = \frac{7}{10^3} + \frac{26}{10^2}-\frac{5}{10^2}$

$= \frac{7 + (26 \times 10) - ( 5 \times 10)}{10^3}\\\\=\frac{7 + 260 - 50 }{10^3}\\\\=\frac{217}{10^3}\\\\= 2.17 \times 10^2 \times 10^{-3}\\\\= 2.17 \times 10^{-1}$

Which term does not belong with the other three?

Brrunno [24]

Answer:

The one that does not belong has a different number of dimensions.

Step-by-step explanation:

Given list consists of:

a line segment (AB)
a plane (CDE)
a line (FG)
a ray (HI)

Three of them have one dimension but the plane has two dimensions,

therefore the plane in the list does not belong with the other three.

So correct answer choice is:

The one that does not belong has a different number of dimensions.
