Answer:
135 cm²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A =
h(a + b)
where h is the height and a, b the parallel bases
Here h = 9, a = 13 and b = 17 , thus
A =
× 9 × (13 + 17)
= 0.5 × 9 × 30
= 135 cm²
Answer:
the green one under the orange one
Step-by-step explanation:
Parallel means never touching, and the 2 bases look like they never touch.
C= 11pi
⇒ d* pi= 11* pi
⇒ d= 11
The diameter is 11~
Answer:
D. -4027
Step-by-step explanation:
After the first two, the integers can be paired so that each pair has a sum of zero.
-2014 +(-2013) +(-2012) + ... (-1) +0 +1 + ... +2012
= -2014 -2013 +(-2012 +2012) +(-2011 +2011) + ... +(-1 +1) +(0)
= -4027 + 0 +0 +0 + ... +0
= -4027
Answer:

Step-by-step explanation:
1. Subtract 10 from both sides. Then:

2. Divide both sides by -2. Notice that the direction of the symbol of the inequality will change. Then:

3. Add 22 to both sides. Then:

4. Divide both sides by -7. Notice that the direction of the symbol of the inequality will change. Then:

5. Subtract 30 from both sides. Then:

6. Divide both sides by -5. Notice that the direction of the symbol of the inequality will change. Then:

7. Subtract 13 from both sides. Then:

8. Add 12 to both sides. Then:
