Answer:

\frac{9}{20}

Step-by-step explanation:

change the mixed number to an improper fraction

2 \frac{1}{4} = \frac{9}{4}

We have to calculate

\frac{1}{3} × \frac{3}{5} × \frac{9}{4}

simplify by cancelling the 3's on the numerator/denominator

then

= 1 × \frac{1}{5} × \frac{9}{4}

multiply the remaining values on the numerators /denominators

= \frac{9}{5(4)} = \frac{9}{20}

2+X/9 = 5x-6/27 SOLVE.
oksano4ka [1.4K]

Answer:

x = 6

Step-by-step explanation:

First, we need to cross multiply on both sides, which gives us:

9 * (5x - 6) = 27 * (2 + x)

45x - 54 = 54 + 27x

Now, we want to isolate x on either side.

We can substract 54 from both sides:

(45x - 54 = 54 + 27x) - 54

45x - 108 = 27x

We then subtract 45 from both sides:

(45x - 108 = 27x) - 45

-108 = -18x

Finally, we divide both sides by -18:

(-108 = -18x) / -18

6 = x

Step-by-step explanation:

Surface area of s sphere = 4πx r^2

Diameter = 1/2 radius

Surface area = 4π x 12^2

= 1809.56 cm^2 = 18.096 m^2

Material required = 71.62 x 18.096

DedPeter [7]

Answer:

376000 pounds

Step-by-step explanation:

What's required of this question is to convert the given weight of plane from tons to pounds

Weight = 188\ tons

Required

Get pounds equivalent

From standard unit of measurements

1\ ton = 2000\ pounds

Multiply both sides by 188

<em>Hence, the weight of the plane in pounds is 376000</em>
