Answer:

245.5 cm²

Step-by-step explanation:

Formula : -

Area of square = side²

Area of square

= 18²

= 324 cm²

Formula : -

Area of circle = πr²

Area of circle

= ( 22 / 7 ) x 5 x 5

= 3.14 x 25

= 78.5 cm²

Area of shaded region

= ( Area of square ) - ( Area of circle )

= 324 - 78.5

= 245.5 cm²

your baseball team has won 6 games and lost 4 games. if the team does not lose any more games, how many games must the team win
puteri [66]

Answer:

<em></em>

<em>The team must win 2 games to have a win : loss ratio o 2.</em>

Step-by-step explanation:

  • <u>Ratio win : loss, r</u>:

       r = total wins / total losses

       

  • <u>Total wins, Tw</u>:

        Call n the number of new wins:

        Tw =number of wins until so far + number of new win = 6 + n

  • <u>Total losses, Tl</u>:

        Tl = number of losses so far + number of new losses = 4 + 0 = 4

  • <u>Target ratio</u>:

        r = 2 ⇒ Tw / Tl = (6 + n) / 4 = 2

Solve for n:

  • (6 + n ) = 4 × 2
  • 6 + n = 8
  • n = 8 - 6
  • n = 2

Hence,<em> the team must win 6 more games.</em>

  • <u>Verification</u>: (6 + 2 ) / 4 = 8 / 4 = 2, which is the target ratio.

4 loads of stone weigh 2/3 ton. Find the weight of 1 load of stone.
lana66690 [7]
4 loads of stone ... 2/3 ton
1 load of stone ... x ton = ?

If you would like to know the weight of 1 load of stone, you can calculate this using the following steps:

4 * x = 2/3 * 1
4 * x = 2/3       /4
x = 2/3 / 4
x = 2/12 = 1/6 ton

The correct result would be 1/6 ton.

Answer:

let \: area \: be \: a, \: height \: be \: h, \: base \: be \: b \\ a =  \frac{1}{2} bh \\ a +  \delta \: a =  \frac{1}{2}  \times (b + \delta \: b)(h + \delta \: h) \\ a + \delta \: a =  \frac{1}{2} (bh + b\delta \: h + h\delta \: b + 0) \\  \delta \: a =  \frac{1}{2} (b\delta \: h + h\delta \: b) \\  \frac{\delta \: a}{a}  =  \frac{b\delta \: h + h\delta \: b}{bh}  \\  \frac{\delta \: a}{a}  =  | \frac{\delta \: h}{h} |  +  | \frac{\delta \: b}{b} |  \\  \frac{\delta \: a}{ 90}  =  \frac{0.5}{15}  +  \frac{0.5}{6}  \\ \delta \: a = 10.5 \:  {cm}^{2}
