White raven [17]

Frank could have 30, 60 , 90 on his uniform

Solution:

Given that, Frank has a 2-digit number on his baseball uniform

The number is a multiple of 10 and has 3 for one of its factors

To find: Three numbers that Frank have on his uniform

Given that,

It's a multiple 10 and has 3 for one of its factors and its a 2-digit number

Let us first find the multiples of 10

The two digit multiples of 10 are:

{10, 20, 30, 40, 50, 60, 70, 80, 90}

From the above list, find the numbers which has 3 as one of its factors

Which means, find the numbers which are divisible by 3

The possible numbers = 30, 60, 90

Thus frank could have 30, 60 , 90 on his uniform

What is a reciprocal?

frozen [14]

The reciprocal is the fraction flipped. so the reciprocal of 1/2 is 2/1. It's used when dividing fractions to make it multiplication, so you use the reciprocal for the second fraction.

Let z be inversely proportional to the cube root of y. When y =.064, z =3

zhuklara [117]

Given:

z be inversely proportional to the cube root of y.

When y =0.064, then z =3.

To find:

a) The constant of proportionality k.

b) The value of z when y = 0.125.

Solution:

a) It is given that, z be inversely proportional to the cube root of y.

$z\propto \dfrac{1}{\sqrt[3]{y}}$

$z=k\dfrac{1}{\sqrt[3]{y}}$ ...(i)

Where, k is the constant of proportionality.

We have, z=3 when y=0.064. Putting these values in (i), we get

$3=k\dfrac{1}{\sqrt[3]{0.064}}$

$3=k\dfrac{1}{0.4}$

$3\times 0.4=k$

$1.2=k$

Therefore, the constant of proportionality is $k=1.2$ .

b) From part (a), we have $k=1.2$ .

Substituting $k=1.2$ in (i), we get

$z=1.2\dfrac{1}{\sqrt[3]{y}}$

We need to find the value of z when y = 0.125. Putting y=0.125, we get

$z=1.2\dfrac{1}{\sqrt[3]{0.125}}$

$z=\dfrac{1.2}{0.5}$

$z=2.4$

Therefore, the value of z when y = 0.125 is 2.4.
