Answer:

2 4/15

Step-by-step explanation:

  1. Change both fractions to improper fractions
  • Multiply the denominator by the whole number then add the numinator
  • Keep the denominator for the final answer
  • So 4 2/3 = 3×4+2/3 => 14/3
  • 2 2/5 = 2×5+2/5 =>12/5

2. Find a common multiple for both denominators and multiply to get it( numerators should be multiplied by the same number as denominators)

  • 14/3 + 12/5 = (14×5 -12×3)/15(a common multiple)
  • (70-26)/15 = 34/15
  • Change the improper fraction(result) to a mixed fraction
  • To do this: divide numerator by the denominator, write result as a whole number, then put the remainder over the denominator (fraction)
  • 34÷15 = 2 remainder 4
  • =2 4/15

Answer:

Volume: 2000 cm^3     Surface Area: 1360cm^2

Step-by-step explanation:

Ok, so we know the formula for volume is length x width x height, so we can substitute in the numbers given, so we end up with:

25 x 4 x 20

when we multiply them together, we get:

2000cm^3. That's the volume.

The formula for Surface Area is:

S.A.=2(lw+wh+lh) . Now we substitute in the numbers given

S.A.=2( (25 x 4)+(4 x 20)+(25 x 20)) . Then we add and multiply, so we get:

S.A. = 1360cm^2

The Surface Area is 1360cm^2.

Hope this helped, sorry if I was wrong somewhere!

The measurement of one angle of a right triangle is 34º.
lorasvet [3.4K]

A triangle's angles always add up to a total 180º, and a right triangle always has an angle equal to 90º.

90º + 34º + xº = 180º

124º + xº = 180º

xº = 56º

It takes a ship 3 hours to cover 72 km with the current and 4 hours against the current. Find the speed of the ship in still wat
earnstyle [38]
X- speed of the ship in still water
a- speed of current
(x+a)- speed with current
(x-a) - speed against current

(x+a)*3=72
(x-a)*4=72

      x+a=24
<u>+    x-a=18
</u>    2x    =42
      x = 21

x+a=24,    21+a=24,    a=3

The speed of the ship in still water = 21 km/h, 
the  speed of the current =3 km/h.
