Answer:

E

Step-by-step explanation:

Since the triangle is right use Pythagoras' theorem to solve for BC

The square on the hypotenuse (BC) is equal to the sum of the squares on the other 2 sides, that is

BC² = 80² + 18² = 6400 + 324 = 6724 ( take the square root of both sides )

BC = \sqrt{6724} = 82 → E

What is the slope in the Y intercept of the line on the graph below
Archy [21]

Answer:

just by looking at the graph you can see that the y int is one, so that eliminates two answers already. Then the slope is rise over run. (best thing to remember in math. rise over run) so pick two points. (0, 1) and (4,0) were the first ones i saw. to get from those two points you go from (0,1) over 4 (thats your run) and from there down 1 (thats your rise) to get to (0,4). You would then do rise over run (and because your rise goes down its negative) to get -1/4 as your slope. The answer is slope= -1/4, Y intercept = 1

Literal equations <br> Solve P=2(l+W) for l
Nina [5.8K]

                          <u> P = 2(L +W)</u>

Divide each side of the equation by 2 :    P/2 = L + W

Subtract  W  from each side :                <em>  P/2 - W  =  L</em>

How many significant figures will be in the answer when you multiply 3.4 x 4.56?
steposvetlana [31]
There are 2 before the decimal point because 3×4=12 and 12 has two digits.
There are 3 after the decimal point because we add together the number of digits after the decimal point in the operands, which is 1 plus 2=3. In all then there are 2+3=5 significant figures.
