Answer:
Step-by-step explanation:
First off, you need to add up AB and BC. You would get the equation:
2(3x-4)=62, since there are two segments. Solve it/simplfy.
6x-8=62 => 6x=70 => x= 11.66666(forever)
Since you alreday solved one, you easily know the answer is c.
Answer:
5/V2=2.5×V2
Step-by-step explanation:
This is an isoscelle right triangle:
x²+x²=5²
2x²=5²
x=5/V2=5×V2/2=2.5×V2
where V2=sqrt(2)
Answer:
Heptagon = 84 ft²
Octagon = 186 yd²
Triangle = 48√3 m²
Step-by-step explanation:
where:
= length of apothem
= perimeter
<u>Heptagon</u>
a = 5.0 ft
p = 33.6 ft
⇒ area = 1/2 x 5.0 x 33.6 = 84 ft²
<u>Octagon</u>
a = 7.5 yd
p = 8 x 6.2 = 49.6 yd
⇒ area = 1/2 x 7.5 x 49.6 = 186 yd²
<u>Triangle</u>
Formula for the apothem of an equilateral triangle :
where 
= side length
a = 4, so:
Now we know the side length, we can calculate the perimeter (p):
p = 3 x 8√3 = 24√3
⇒ area = 1/2 x 4 x 24√3 = 48√3 m²
Answer:
4.07
Step-by-step explanation:
11 1/5 divided by 2 3/4
= 11 1/5 ÷ 2 3/4
= 56/5 ÷ 11/4
= 56/5 × 4/11
= (56*4) / (5*11)
= 224/55
= 4.07
The best estimate of 11 1/5 divided by 2 3/4 is 4.07
