Answer:
a) Surface area = 616 cm²
b) Volume = V = 1083 cm³
Step-by-step explanation:
Surface area and volume of a regular triangular pyramid that has a base edge of 16 cm and a slant height of 15 cm
a) Formula for surface area = Base area × 1/2(perimeter × slant height)
Base area = Base edge²
=( 16 cm)² = 256 cm²
Perimeter = Base edge × 3
= 16 cm × 3 = 48 cm
Hence:
Surface Area = 256 cm² + 1/2(48 × 15)
= 256 cm² + 360 cm²
= 616 cm²
b) Volume = 1/3 × Base area × Height
1082.758616785cm³
Approximately = 1083 cm³
Answer:
c) The reduced form of the given fraction 
Step-by-step explanation:
Here, the given expression is "24 over 30".
The given expression is is equivalent to 
Now by Prime Factorization:
24 = 2 x 2 x 2 x 3
30 = 2 x 3 x 5
⇒ The common factors in 24 and 30 is 2 x 3 = 6
So, 
Hence the reduced form of the given fraction
Yes, you'd be able to play.
37/42 = .88 = 88%
So you've attended more than 85% of the practices.
60v = $15
60v/60 = $15/60
v = 0.25
The original value of the baseball card is $0.25
