Mrs. Larson mowed 2/5 of her lawn. Her son mowed 1/4 of it. How much of her lawn still needs to be mowed?

answer:

125 yards

explanation:

75+50=125. that is my answer

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft

14 x 10 5

step-by-step explanation:

10 5 = 100,000

14x10,000 = 140,000
