Answer:
Area = 1.54
Step-by-step explanation:
Area = π![r^{2}](https://tex.z-dn.net/?f=r%5E%7B2%7D)
π = 3.14
diameter = 1.4
radius (half of diameter) = 0.7
Area = 3.14 x ![0.7^{2}](https://tex.z-dn.net/?f=0.7%5E%7B2%7D)
Area = 3.14 x 0.49
Area = 1.5386
round to the nearest hundredth:
1.5386 = 1.54
Answer:
15 ft
Step-by-step explanation:
Hi, the illustration for the problem is a right triangle with:
hypotenuse (C)= the length of the ladder = L
horizontal side(A) = distance from bottom of the ladder to the building = L - 6
vertical side(B) = distance from the top of the ladder to the bottom of the building = L - 3
So, we can use Pythagoras formula:
A2 +B2= C2
(L – 6 )² + (L-3)² = L²
L²-12L+36+L²-6L+9 =L²
L2 -18L+45 =0
APPLYING QUADRATIC FORMULA WE OBTAIN:
L =15 OR L=3
If L=3
Vertical side = L-3 = 0 (Length can´t be 0)
So L=15
You would round 1506 to 1500 and and do not round 2. So then you woulddo 1500 divided by 2 to get 750!
First add 25 to both sides of the inequality.
You get 4x < 150
Now divide both sides by 4.
You get x < 37.5
So x can be anything less than 37.5, such as 36, 35 or 34.
