(cell tower)/((45 +3) m) = (2 m)/(3 m)
(cell tower) = (48 m)(2/3) = 32 m

B. 32 m . . . . . is the appropriate selection

Answer:

B. 32 m

Step-by-step explanation:

Here we can join the top of the cell phone tower to the point B. Similarly, we can join the pole top to the point B.

We will get a two similar triangles.

The ratio of similar triangles are in proportion.

Let's take "x" be height of the cell phone tower.

Cell phone tower          Cell phone tower shadow

-------------------------  =  ------------------------------------

Pole                                    Pole shadow

x/2 = (45 + 3)/3

x/2 = 48/3

x/2 = 16

Multiplying both sides, we get

x = 2*16

x = 32 meters

Therefore, the height of the cell phone tower is 32 meters.

It is B. 32 m

Hope this will helpful.

Thank you.

The original price of a camera is $150. If a discount of 30% is given, what is the discounted price of the camera?
MArishka [77]
So, 30% is 0.30, but since you are taking off 30%, you are going to have 70% of the price which is 0.70. The word "of" lets you know that you are going to multiply. So, what you do is 150•0.70=105. The discounted price is $105

Can you please help me with this
Vitek1552 [10]

Answer:

log9

Step-by-step explanation:

Using the rules of logarithms

logx + logy = log(xy)

logx - logy = log(\frac{x}{y})

logx^{n} ⇔ nlogx

Given

2(log18- log3) + \frac{1}{2}log\frac{1}{16}

= 2(log(\frac{18}{3} ) ) + log(\frac{1}{16}) ^{\frac{1}{2} }

= 2log6 + log\frac{1}{4}

= log6² + log\frac{1}{4}

= log36 + log\frac{1}{4}

= log( 36 × \frac{1}{4} )

= log9

What is the arc measure of DBC in degree
aliya0001 [1]

The length of both AB and DC is the same.

19 degrees

We want to know the arc measure for the whole circle, except for DC. So, we can subtract the arc measure of DC from 360 to find DBC. Since we found DC above, all we need to do is subtract.

360 - 19 = 341

DBC = 341 degrees

Hope this helps!! :)
