5 feet is 5*12=60 inches. Therefore, our ratio is 28:60. Dividing both terms by 4, we see that the most simple ratio is 7:15.
To find the length of the ladder, you need to do Pythagorean theorem.
50^2 + 30^2 = x^2
2500 + 900 = x^2
x^2 =3400
x= square root of 3400
58.31 OR 10 root34
To find the angle:
tan theta = opposite/adjacent
50/30 = 5/3
theta = tan inverse of 5/3
= 59.04
Expanded form is like this 300 plus 20 plus 7 plus .40 plus .6
Is this the algebra 1 blue book, first the answers are on the last few pages.second , let me explain how to find slope intercept form you need to isolate the y make it by itself
Step-by-step explanation:
the total area of circles =
(2 × π × 1²) + (3 × π × 0.5²)
= (2π) + ( 3× 0.25×π)
= 2π + 0.75π
= 2.75π
assume π=3.14
so, the total area =
2.75 × 3.14 = 8.635
