What is the volume of the triangular prism shown below ?
jekas [21]

Answer:

B

Step-by-step explanation:

The volume (V) of a triangular prism is

V = area of triangular end × length

area of Δ = \frac{1}{2} bh

where b is the base and h the perpendicular height

here b = 8 and h = 5, so

area = 0.5 × 8 × 5 = 20 units²

the length of the prism is 10, hence

V = 20 × 10 = 200 units³

A square outdoor patio with side length x feet is surrounded by a brick walkway that is 4 feet wide. What is the area of the wal
Masja [62]

Answer:

Area of walkway = 16(x+4) ft^{2}

Step-by-step explanation:

Length of the sides of the square outdoor = x feet

Area of the square outdoor = length x length

                            = x * x

                            = x^{2} ft^{2}

The square outdoor is surrounded by 4 feet of walkway. So that,

length of the walkway = (x + 2(4))

                                     = (x + 8)

Area of walkway with outdoor = (x + 8)*(x + 8)

                                      = (x^{2} + 16x + 64) ft^{2}

Area of walkway = Area of walkway with outdoor - Area of the square outdoor

                            = ( x^{2} + 16x + 64) - x^{2}

                            = 16x + 64

Area of walkway = 16(x+4) ft^{2}

triangle XYZ has vertices X(6,-2.3), Y(7.5,5), and Z(8,4). when translated X' has coordinates (2.8,-1.3). Write a rule to descri
Ronch [10]
(x-3.2, y+1) . Y'=(4.3, 6)  Z'=(4.8, 5)

The preimage (6,-2.3) differs from the image (2.8,-1.3) by subtracting the coordinates of the pre-image from the image leaving a -3.2 difference for x and a +1 for the y value.  apply this rule to Y and Z to get Y' and Z'.
