At 6:00 PM, a flagpole that is 35 feet tall casts a shadow that is 50 feet long. At the same time, how long will a person's shad
sertanlavr [38]

<u>Answer:</u>

The length of the person’s shadow is 5.7ft

<u>Explanation:</u>

Length of the flagpole =a= 35ft

Length of the shadow of the flagpole= b=50ft

Length of the person=c= 4ft

Suppose the length of the person’s shadow is=d

According to the  rules of trigonometry

\frac{\text { Length of the flagpole }}{\text { Length of the shadow of the flagpole }}=\frac{\text { Length of the person }}{\text { Length of the person's shadow }}

\frac{a}{b}=\frac{c}{d}

\frac{35}{50}=\frac{4}{d}

35d=200

d=\frac{200}{35}

d=5.7ft  

Hence, The length of the person’s shadow is 5.7ft.

Someone plsss help me!!!!!
MariettaO [177]

Answer:

x = 2

Step-by-step explanation:

the formula for this problem is

Area = 1/2 base x Height

step 1) plug in what we know

5 = 1/2 base(5)

step 2) switch sides

1/2 base x 5 = 5

step 3) divide both sides by 1/2 x 5

\frac{1/2 base( 5)}{1/2(5)} = \frac{5}{1/2(5)}

step 4) Simplify

\frac{1/2 base (5)}{1/2 (5)}: b

step 5) Simplify

\frac{5}{1/2(5)}: 2

step 6) now you have gotten the answer<u> x = 2</u>

Two cars which are 40 miles apart start moving simultaneously in the same direction with constant speeds. If the speed of the ca
IgorC [24]

Answer:

5mph

Step-by-step explanation:

Given that two cars are 40 miles apart at the beginning.

They started at the same time with speeds 48 mph and 56 mph respectively

Since both cars are travelling in the same direction,

Relative velocity = Speed of the behind car-Speed of the first car

=56-48 =8mph

To catch the I car, the second car has to travel a distance of 40 miles extra in the same time as the I car

i.e. speed to be made up by the second car = 40 miles

Relative velocity per hour              = 8mph

Hence time taken to catch up = \frac{40}{8} =5mph
