How many feet long is the shadow of a 15-foot flagpole if a 5-foot woman standing at the base of the flagpole has a shadow that

Vikentia [17]

The height of flagpole is 12.5 feet.

Step-by-step explanation:

Given,

Height of woman = 5 foot

Shadow of woman = 6 feet

Ratio of height to shadow = 5:6

Shadow of flagpole = 15 foot

Height of flagpole = x

Ratio of height to shadow = x:15

Using proportion;

Ratio of height to shadow :: Ratio of height to shadow

$5:6::x:15\\$

Product of mean = Product of extreme

$6*x=15*5\\6x=75$

Dividing both sides by 6

$\frac{6x}{6}=\frac{75}{6}\\x=12.5$

The height of flagpole is 12.5 feet.

A cylindrical hole is bored through a steel block, and a cylindrical piston is machined to fit into the hole. The diameter of th

prisoha [69]

Answer:

The diameter of the hole is 20.04 ± 0.01 cm

The diameter of the piston is 19.92 ± 0.04 cm.

We are given that The clearance is one-half the difference between the diameters.

So, Clearance = $\frac{1}{2}(20.04-19.92)$

= $0.06$

Uncertainty in the estimate = $\frac{1}{2}(0.01+0.04)$

= $0.025$

So, Clearance with uncertainty is $0.06\pm 0.025$

Hence the clearance is 0.06 and the uncertainty in the estimate. is 0.025
