"The volume of the trapezoidal prism is 1279.152 cubic feet. Determine the height of the trapezoidal base"

Diano4ka-milaya [45]

Answer:

The height of the trapezoidal base is 7.2 ft.

Step-by-step explanation:

Consider the provided information.

The volume of trapezoidal prism is the area of the cross-section × the length.

$V=BH$

Where B is the area of base, H is the length and V is the volume.

The length of the prism is 25.2ft and volume is 1279.152

$1279.152=B(25.2)$

$B=50.76$

Hence, the base area is 50.76 ft².

The base is trapezoid.

The area of trapezoid is $B=\frac{1}{2}(b_1+b_2)h$

Substitute B=50.76, $b_1=10\ and\ b_2=4.1$ in above formula.

$50.76=\frac{1}{2}(10+4.1)h$

$50.76=7.05h$

$h=7.2$

Hence, the height of the trapezoidal base is 7.2 ft.

A fair spinner has 12 equal sections: 5 red 4 blue and 3 green. its Spun twice what is the probability of getting the same colou

VLD [36.1K]

Answer:

25/72

Step-by-step explanation:

P( blue) = blue / total = 4/12 = 1/3

P ( blue, blue) = 1/3 * 1/3 = 1/9

P ( red) = red / total = 5/12

P ( red, red) = 5/12 * 5/12 = 25/144

P ( green) = green /total = 3/12 =1/4

P ( green , green) = 1/4 * 1/4 = 1/16

Add these together to get

P( same colour twice) = 1/9+ 25/144 + 1/16

=16/144 + 25/144 + 9/144

=50/144

=25/72
