Answer: 2.25x 10^{-17}

Scientific notation is used in science because the number can be vary from so much that using decimal is making it hard. The number expressed in 10^{x} form. Both number in the question is already in scientific notation. Then to multiply the number and keep it at scienfitic notation the calculation should be:

2.5 x 10^{-8}x 9 x 10^{-10}= 22.5 x 10^{-18}= 2.25x 10^{-17}

Help asap!!<br> a. SG<br> b. HS <br> c. GT<br> d. FT
Evgen [1.6K]

Answer: choice c. GT

===================================

Explanation:

A median is a segment that runs from a vertex point to the midpoint of the opposite side. Segment GT starts at the vertex G and goes to the midpoint T. We know that T is a midpoint since FT and TH are both 3 units long

since FT = TH, we know that FT is half as long as FH; or put another way, FH is twice as long as FT.

---------

Extra info

* Segment HS is an angle bisector: it cuts angle GHF in half.

* If you have two median lines, then you can find the centroid of the triangle.

on Saturday Leo and his brother drove into town to visit their mom Leo is trying to remember how much he spent on gas and tolls
Gwar [14]

Let t be the number of tolls they crossed.

Amount they spent at each toll = $1.75.

Amount they spent at gas station = $28.

Let C be the total amount they spent on gas and tolls.

If they crossed 1 toll, then

C = 28 + 1.75(1).

If they crossed 3 tolls, then,

C = 28 + 1.75(3)

If they crossed t tolls, then,

C = 28 + 1.75t

Here, the terms are 28 and 1.75t and the factors are 1.75 and t.
