Answer:
11.83
Step-by-step explanation:
97.5 squared root + 1.96
√97.5 + 1.96
9.87 + 1.96
= 11.83
$6.84 divided by 18= .38 which means 38 cents per pen
$8.40 divided by 30= .28 which means 28 cents per pen
so $8.40 for 30 pens is a better deal than 18 pens for $6.84 by ten cents.
Answer:
Step-by-step explanation:
-u-5+10u-25=9u-30
it was easy.
This is the application of trigonometry. The distance of the ladder from from the wall will be given by:
cos θ=(adjacent)/(hypotenuse)
θ=72°
adjacent=base (distance the ladder to base of the wall)= xft
hypotenuse=length of the ladder.
Therefore plugging our values in the formula we get:
cos 72=x/15
x=15 cos 72
x=4.635 ft
Hence we conclude that the foot of the ladder is 4.635 ft away from the base of the wall.
