Th area of a right triangle is A = 1/2 (ab), where a and b are the legs of the right angle. So area of the base is, A = 1/2 (9 x 12) = 108 cm2. With 2 bases, total area of base is 108 times 2, which is equal to 216 cm2. The other side of the triangular base nypotenuse) can be computed by Phythagorean theorem. Hypotenuse = square root of sum of the suare of 9 and 12. This is equal to 15 cm. There are other 3 rectangular faces with the following dimensions: 9 by 10 cm, 12 by 10 cm and 15 by 10 cm. Area of the other faces are 90, 120 and 150 cm2, by multiplying the length and width, only. Total area is 576 cm2.

Answer:
7/8
Step-by-step explanation:
we need to same denominator. 3/4 is equal to 6/8
1/8+6/8 is 7/8.
Answer: A. $1.42
Explanation:
-Postcards = P
-large envelope = E
14p + 5e = 12 or 5e = 12 -14 p
10p + 15e = 24.8
5e = 12 - 14 p multiply by 3
15e = 36- 42 p
Combine 10p + 15e = 24.8 and 15e = 36- 42 p
That equals 10p + 36 - 42p = 24.8
10p + 36 - 42p = 24.8
11.2 = 32 p
P = 0.35
Bring down the equation 5e = 12 - 14p and substitute
5e = 12 - 14p
5e = 12 - (14 x 0.35)
5e = 12 - 4.90
5e = 7.10
e = 1.42
Net worth is what is owned minus what is owed.
WHAT THE OWN
- $200,000
-$20,000
-$15,000
-$100,000
TOTAL IS $335,000
OWED
-$300,000
-$15,000
TOTAL IS $315,00
owned - owed
= 335,000 - 315,000
=$20,000
the families net worth is $20,000
