The answer is 3.75 cm^3.

First you have to change 12 mm to cm, which would be 1.2 cm. The formula for the volume of a triangular prism is 1/2 x a x c x h. So, 1/2 (2.5) x (1.2) x (2.5) = 3.75 cm^3

Mashutka [201]

Answer:

$2,677.72

Step-by-step explanation:

L = 3C

P

4P + 3L = 1,580.62

2L + 5C = 1,340.90

4P + 5L + 3C = ?

2L + 5C = 1,340.90

6C + 5C = 1,340.90

11C = 1,340.90

C = 121.90

121.90 * 3 = 365.70

L = 365.70

4P + 3L = 1,580.62

365.70 * 3 = 1,097.10

4P = 483.52

P = 120.88

C = 121.90

L = 365.70

P = 120.88

4P + 5L + 3C = ?

4(120.88) + 5(365.70) + 3(121.90) = 2,677.72

3x° = (5x-20)° [Interior Alternate Angle]

=> 3x° = 5x° - 20°

=> 5x° - 3x° = 20°

=> 2x° = 20°

=> x° = \frac{20°}{2}

<h3>=> x° = 10°</h3>

What is the value of "twelve more than the quotient of a number and two, decreased by four" when n = 4?
Blizzard [7]

Answer:

10

Step-by-step explanation:

Let

the number = n

The quotient of a number and two = n / 2

twelve more than the quotient of a number and two,

(n/2 + 12)

twelve more than the quotient of a number and two, decreased by four

(n/2 + 12) - 4

when n = 4?

(n/2 + 12) - 4

= (4/2 + 12) - 4

= (2 + 12) - 4

= 14 - 4

= 10
