The equation is as read; 17.2 + 12.9 should equal 30.1.

Just add [looks like you subtracted instead] straight down getting 301 then moving the decimal down too.

The answer would be 30.1 since you have to add the decimals first and then the whole numbers

svet-max [94.6K]

Answer:

$m=\frac{1}{2}$

Step-by-step explanation:

defition of slope(m) of a line:

$m=\frac{Y_b-Y_a}{X_b-X_a}$

A=(-1,-5)=(Xa,Ya) then Xa= -1 and Ya= -5

B=(3,-3)=(Xb,Yb) then Xb=3 and Yb= -3

$m=\frac{-3-(-5)}{3-(-1)} \\\\m=\frac{-3+5}{3+1} \\\\m=\frac{2}{4} \\\\m=\frac{1}{2}$

Help please. this doesn't make sense

Answer:

a = 39.2650873379cm

b = 11.5529459767cm

Step-by-step explanation:

a - Use the area of a triangle equation - 1/2 * a * b * Sin(C)

1/2 * 8 * 10 * Sin(79) = 39.2650873379cm

b - Use the cosine rule - c^2 = a^2 + b^2 - (2 * a * b * Sin(C)

64 + 100 - (2 * 8 * 10 * Cos(79)) = 133.4705607398

c = square root of 6.9396506484 = 11.5529459767cm

Put to however many significant figures / decimal places required.
