Answer:
$7.58
Step-by-step explanation:
Think about it, (S+C), each flavor costs $3.97 per carton, and there's 2 cartons. $3.79 x 2 = $7.58
The Pythagorean theorem is helpful here.
.. x^2 +20^2 = 50^2
.. x^2 = 2500 -400 = 2100
.. x = 10√21 ≈ 46 . . . . feet
Step-by-step explanation:
the lengths of any line (side, height,...) in A is twice as long as in B.
now, the area of a triangle is
baseline × height / 2
so, two lines are multiplied. that means the factor 2 gets multiplied in 2 times. and that means the area increases by the factor 2×2 = 4
therefore, the area of A is
40.5 × 4 = 162 cm²
