A water tower casts a 100- foot shadow. At the same time, an 8- foot street sign casts a shadow of 6 feet. what is the height of

Elina [12.6K]

Set up and solve an equation of ratios. Comparing shadow lengths, we get 100/6; comparing heights, we get x/8. Set these two ratios equal to one another and solve the resulting equation for x:

100 x
----- = ------ Then 6x=800, and x = 800 feet^2 over 6 feet. Your answer

Determine whether

lora16 [44]

Answer:

(a) and (b) are not equivalent

(c) is equivalent

Step-by-step explanation:

Given

$\frac{25^m}{5}$

Required

Determine an equivalent or nonequivalent expression

$(a)\ 25^{m-1$

We have:

$25^{m-1$

Apply law of indices

$25^{m-1} = \frac{25^m}{25}$

<em>This is not equivalent to </em> $\frac{25^m}{5}$ <em></em>

$(b)\ 25^{2m - 1}$

We have:

$25^{2m - 1}$

Apply law of indices

$25^{2m - 1} = \frac{25^{2m}}{25}$

<em>This is not equivalent to </em> $\frac{25^m}{5}$ <em></em>

<em></em>

<em /> $(c)\ 5^{2m-1}$ <em />

We have:

<em /> $5^{2m-1}$ <em />

Apply law of indices

<em /> $5^{2m-1} = \frac{5^{2m}}{5^1}$ <em />

<em /> $5^{2m-1} = \frac{5^{2m}}{5}$ <em />

<em>Evaluate the numerator</em>

<em /> $5^{2m-1} = \frac{25m}{5}$ <em />

<em />

<em>This is an equivalent expression</em>

Three tanks are capable of holding 361,841, and 901 of the greatest vessel winch can be used to fill each one of them on exact n

daser333 [38]

Answer:

Tank which is capable of holding 1 can fill each one of the tanks an exact number of time.

Step-by-step explanation:

Three tanks are capable of holding $361,841,901$

To find which tank can be used to fill each one of them an exact number of time, find $HCF(361,841,901)$

$361=19^2\\841=29^2\\901=17(53)$

Therefore,

$HCF(361,841,901)=1$

So, tank which is capable of holding 1 can fill each one of the tanks an exact number of time.
