.394= 197/500

you can't make it a mixed number since there isn't a whole number as with an improper fraction.

The fraction would be 394/1000. The answer can't be a mixed number because 394 isn't higher than 1000. It can't be improper for the same reason.

Maria who is 6 feet tall stand 20 feet away from the base of a tree she looks up at the top of the tree at 43° angle of elevatio
grandymaker [24]

Answer:

24.7 feet

Step-by-step explanation:

Maria who is 6 feet tall stands 20 feet away from the base of a tree she looks up at the top of the tree at a 43° angle of elevation.

what is the approximate height of the tree rounded to the nearest 10th?

We solve the above question using the Trigonometric function of Tangent

tan θ = Opposite/Adjacent

θ = Angle of elevation

Adjacent = Distance from the base of the tree = 20 feet

Opposite => Height of the tree = x

θ = 43°

tan 43 = x/ 20 feet

x = tan 43 × 20 feet

x = 18.650301723 feet

Approximately = 18.7 feet

We are told in the question that Maria is 6 feet tall

Therefore, the height of the tree = Maria's height + Height

= 6 feet + 18.7 feet

= 24.7 feet

to prepare for a math test Eric study three times as long as Kendra and 1/2 as long as Geraldo. How long did Geraldo study if Ke
sp2606 [1]

Let

x---------> time in minutes used by Eric to study

y---------> time in minutes used by Kendra to study

z---------> time in minutes used by Geraldo to study

we know that

x=3y------> equation 1

x=0.5z

z=2x--------> equation 2

y=20 minutes --------> equation 3

substitute equation 3 in equation 1

x=3*20=60 minutes

find the value of z in equation 2

z=2*60=120 minutes

therefore

<u>the answer is</u>

The time in minutes used by Geraldo to study was 120 minutes
