Step-by-step explanation:

40% = 0.40

420/1.4 = 300

To check:

300 * 0.40 = 120

Answer:

300

Step-by-step explanation:

Let x represent the original number.

Then the number plus a 40% increase comes out to 1.40n.

This 1.40n = 420. Solve this for n:

n = 420/1.40 = 300

the unknown (original) number was 300.

AS we know that:

$V=SA*h$

And we have the volume and we can calculate the SA,,,

So that, we can conclude:
$h= \frac{V}{SA} = \frac{323.5}{\pi (7)^2} =2.1015~~in$

Are you satisfied?

What is the missing length.

nasty-shy [4]

Answer:

$KS = 12$

Step-by-step explanation:

Given that ∆KLM ~ ∆RSK, $\frac{KL}{KR} = \frac{KM}{KS}$ (similarity theorem)

KL = 65

KR = 65 - 52 = 13

KM = 60

KS = ?

$\frac{65}{13} = \frac{60}{KS}$

Cross multiply

$65*KS = 60*13$

$65*KS = 780$

$\frac{65*KS}{65} = \frac{780}{65}$

$KS = 12$
