Ireally need 99 points a 9 foot ladder leans against a building the foot of the ladder is 3 feet away from the building if a 6-foot ladder is propped against the building at the same angle with the ground the foot of the new ladder would be how far away from the building

2'

Step-by-step explanation:

ladder, bldg wall n ground form a triangle

cuz the two ladders are at the same angle

the two triangles are similar

their sides are in the same ratio:

9:6 = 3:x where x is the distance from bldg of the 6' ladder

x=3*6/9

= 2'

step-by-step explanation:

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
