asambeis [7]

Answer:

he cable car's elevation will be 750 feet after 15 minutes

Step-by-step explanation:

Given:

elevation, e =2,000 feet

rate, I = 50 feet/minute

The equation that models the car's elevation, e, after t minutes is e = |t

The cable car's elevation will be 750 feet after how many minutes?

since, e = It

for 2,000 feet = 50 feet/minute  * t

t = 2000/50 =40minutes

using the same constant rate, I for 750ft, T =

since, e = It

for 750 feet = 50 feet/minute  * t

t = 750/50 =15minutes

G is the centroid of triangle ABC. If BF=12, what is BG?<br> BG=?
lutik1710 [3]

Answer:

BG = 8

EXPLANTAION :

we know that centroid of a triangle divides the median into ratio of 2 : 1 so,

BG : GF = 2 : 1

now, let's take BG as 2x and GF as x

and here, BG + GF = BF

So,

=》2x + x = 12

( because, BF = 12 )

=》3x = 12

=》x = 12 ÷ 3

=》x = 4

hence, x = 4

from here,

=》BG = 2x

=》BG = 2 × 4 = 8
