<h3>let's solve:</h3>
to find <u>how far the ladder is from the foot of the </u><u>wall </u>
we will use tan function because we are given opposite and angle
we need to find adjacent
let adjacent be BC
we will use a little bit algebra to figure out BC
Answer:
the answer is c. 1 inch=27 feet
Step-by-step explanation:
32 is to big and 22 is to small but 27 will fit perfectly because its 20 inches
If 85 blinks = 15 minutes
then 51 blinks = x (cross multiply)
85 × x = 51 × 15
85x / 85 = (51 x 15) / 85
x = (51 × 3) / 17
x = 3 × 3
x = 9
so he blinked 51 times in 9 minutes
if 1 minute = 60 seconds
then 9 minutes = x (cross multiple)
1 × x = 9 × 60
x = 540
therefore 540 seconds passed when he blinked 51 times
