Answer:

V(a) = 3,750mm^3

Step-by-step explanation:

for mathematically similar figures scale factor (sf) is common

that is if their lengths ratio is 3

then their areas ratio will be 3^2

volume's ratio will be 3^3

So here in this problem we have Surface Areas

by that we will find sf^2

SA(b) / SA(a) = 10478 / 1550 = 6.76

sf^2 = 6.76

sf = 2.6

now volumes ratio will be

V(b) = sf^3 * V(a)

= 2.6^3 * V(a)

= 17.576 * V(a)

Substitute this in the Volume equation given

V(b) - V(a) = 62160

=> 17.576 * V(a) - V(a) = 62160

=>16.576 * V(a) = 62160

=> V(a) = 62160 / 16.576

=> V(a) = 3,750

Turn the following decimals into a Hours, minutes, seconds format.

Dvinal [7]

Answer:

It is 2 hours, 22 minutes, 48 seconds.

The 2 is obviously 2 hours. For the minutes, .38 * 60 = 22.8, so the minutes is 22. 0.8 * 60 = 48. So 2 hours, 22 minutes and 48 seconds.

$3x^{2} +1=28$

Step 1 : subtract 1 from both sides

$3x^{2} =27$

Step 2 : Divide both sides by 3

$\frac{\frac{3x^{2} }{3} }{\frac{27}{3} }$

$x^{2} = 9$

Step 3 : Find the square root of 9

$\sqrt{9} = 3$

x= (-3,3)

<h3>Given :-</h3>

Pranav ran 20.3 km more than Branda

Pravin ran 38.6 km

$\\ \\$

To find :

No. of kilometers did Brenda run.

$\\ \\$

No. of kilometers ran by Brenda be x.

$\\ \\$

<h3>Solution:</h3>

$\\ \\$

Equation formed:-

$\\ \\$

Total distance covered by Pravan = More distance covered by Pravan + distance covered by Brenda.

Therefore:-

$\\ \\$

$\leadsto \sf38.6 = 20.3 + x$

Write the equation

$\\ \\$

$\leadsto \sf38.6 - 20.3 =x$

When we transfer 20.3 to left side the positive sign (+) will change into negative sign (–)

$\\ \\$

$\leadsto \sf x = 38.6 - 20.3$

Arrange the equation because x is always represented at left side.

$\\ \\$

$\leadsto \boxed {\pmb{\sf x = 18.3}}\star$

After subtracting 38.6 with 20.3 we will get result as 18.3 .

$\\ \\$

$\therefore \red{ \underline{ \pmb{\frak{Distance ~ covered ~by ~Brenda~ is ~equal ~to~18.3~kilometers}}}}$
