Michelle wants to determine the height of a flag pole outside of her school. she places a meter stick next to the flag pole and measures the shadow of the meter stick and the flag pole. if the meter stick has a shadow of 140 centimeters and the flag pole has a shadow of 35 meters, then how tall is the flag pole a: 250 meters b: 12.5 meters c: 400 meters d: 25 meters

Step-by-step explanation:

The shadow of the meter stick is 40% greater than its actual length.

height of the flag pole, h

h x 1.4 = 35m

h = 35/1.4

= 25 meters

step-by-step explanation:

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
