The dimensions of a triangular prism are shown.
Serhud [2]

9514 1404 393

Answer:

  B.  32 square inches

Step-by-step explanation:

Each of the two triangular faces has an area of ...

  A = (1/2)bh = (1//2)(6 in)(4 in) = 12 in²

The lateral surface area is the product of the prism height (0.5 in) and the perimeter of the base.

  LA = (0.5 in)(5 in +5 in + 6 in) = 8 in²

So, the total area is the area of the two base and the lateral area:

  SA = 2A +LA

  SA = 2(12 in²) +8 in² = 32 in²

The surface area of the prism is 32 square inches.

The carpet Danil has chosen for his new recreation room costs $8.99 per square metre. this room measures 15ft by 18ft. how much
Fudgin [204]

Answer:

$225.50 (nearest cent)

Step-by-step explanation:

1 foot ≈ 0.3048 m

Width of room = 15 ft ≈ 15 x 0.3048 = 4.572 m

Length of room = 18 ft ≈ 18 x 0.3048 = 5.4864 m

Area of room = width x length = 4.572 x 5.4864 = 25.0938208... m²

Cost of carpet = $8.99 per m²

Total cost of carpet = 25.0938208 x 8.99 = $225.50 (nearest cent)

Greetings!

Convert both terms into improper fractions:
=9/1-59/8
Find the LCM.
=72/8-59/8
Simplify.
=13/8
Convert to Mixed Number.
=1 \frac{5}{8}

The second answer would be correct.

Hope this helps.

If f(x) is linear, f(− 1) = 9 , and f(2) =− 24, find f(x).
professor190 [17]

Answer: Equation of st line is Y= -9X + 141

Step-by-step explanation: Given Y= 24 when X = 13 and Y = 87 when X = 6

Let the equation be Y = mX + C

24 = m*13 +C

and 87 = m* 6 +C

Give m = -9 and C = 141

Equation of st line is Y= -9X + 141
