PLEASE HELP ME!!
6. Michele wanted to measure the height of her school's flagpole. She placed a mirror on the
ground 48 feet from the flagpole, then walked backward until she was able to see the top of the
pole in the mirror. Her eyes were 5 feet above the ground and she was 12 feet from the mirror.
Using similar triangles, find the height of the flagpole to the nearest tenth of a foot.
A) 20 ft
B) 38.4 ft
C) 55 ft
D) 25 ft

answer: 457.14

step-by-step explanation:

205 - 45 = 160

160 / .35 = 457.142857

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1
