If z varies inversely as w^2, and z=10 when w=6, find z when w=2
Dmitry [639]

Answer:

90

Step-by-step explanation:

If z varies inversely as w^2 then:

z=k/(w^2)  

z=10 when w=6:

10=k/36---> k=360

z=k/2^2

z=360/4=90

My textbook doesn't explain square roots well. Can someone help me understand? Example 1 is the square root of 9
Vilka [71]
A square root is doing the opposite of squaring. Squaring is multiplying a number by itself. Square rooting is trying to figure out what number squares into the number you have currently.
For your Example 1, the square root of 9 is 3.
3 x 3 = 9.
Some better examples are:
4 x 4 = 16.
4 is the square root of 16, and 16 is the square of 4.

the length, breadth and height of a cuboid are in the ratio 5:4:2 if the volume of cuboid is 5000 cm,then what will be the surfa
Sonbull [250]

Answer:

  1900 cm²

Step-by-step explanation:

We can use the given ratios and volume to find the scale factor for the dimensions. Knowing the dimensions, we can compute the surface area using the formula for a cuboid.

__

<h3>dimensions</h3>

Let k represent the scale factor. Then the actual dimensions will be 5k, 4k, and 2k. The actual volume will be ...

  V = LWH

  5000 cm³ = (5k)(4k)(2k) = 40k³

  k³ = (5000 cm³)/40 = 125 cm³

  k = ∛(125 cm³) = 5 cm

The cuboid dimensions are 5(5 cm) = 25 cm, 4(5 cm) = 20 cm, and 2(5 cm) = 10 cm.

__

<h3>area</h3>

The surface area of the cuboid can be computed from ...

  A = 2(LW +H(L +W))

  A = 2((25 cm)(20 cm) +(10 cm)(25 +20 cm))

  A = 2(500 cm² +(10 cm)(45 cm)) = 2(950 cm²) = 1900 cm²

The surface area of the cuboid is 1900 cm².

Is (2×3)×4=2×(3×4) an example of associative property of multiplication?
xeze [42]

Answer:

Yes.

Step-by-step explanation:

<u>Associative property of multiplication is:</u>

(A×B)×C = A×(B×C).

It says that "The way of grouping of terms doesn't change the product."

So, given example (2×3)×4=2×(3×4) is an example of associative property of multiplication.

\rule[225]{225}{2}

Hope this helped!
