Answer:

incorrect

Step-by-step explanation:

we are finding area which is squared, or we can put it in an equation, (0.5*20)*(0.25*20) or 0.5*0.25*20^2 which equals 50      but (0.5*0.25)*20 only equals 2.5    therefor he is incorrect and the correct answer would be 20^2 or 400 times the area.

hope this helps :)

Find the cosine of L
aleksandr82 [10.1K]

Answer:

0.42

Step-by-step explanation:

use the attached as reference

recall that for a right (90°) triangle, with any acute angle θ,

cos θ = length of adjacent side / length of hypotenuse

in our case, for angle I, the adjacent side is HI = 36 units and the hypotenuse is IJ = 85 units

by the above formula,

cos I = length of adjacent side / length of hypotenuse

= 36 / 85

= 0.42353

= 0.42 (rounded to nearest hundredth)

The mistake he made was that he did not consider units of measurement while comparing the lengths

He has to convert the both quantities into the same unit to compare the lengths either centimeters to meters or meters to centimeters

Step-by-step explanation:

Length of desk  =  1 meter

Henry's name tag = 8 cm

Henry says that his name tag is 7 cm longer than the desk. The mistake he made was that he did not compare the units of both quantities. He just subtracted 1 from 8 and got 7. Meter is a larger unit and centimeter is a smaller unit. In order to compare the lengths of the desk and his name tag the units have to be same.

Hence

The mistake he made was that he did not consider units of measurement while comparing the lengths

He has to convert the both quantities into the same unit to compare the lengths either centimeters to meters or meters to centimeters
