A prism with a triangular base has a volume of 432 cubic feet. The height of the prism is 8

Rashid [163]

Answer:

9 feet

Step-by-step explanation:

Given:

A prism with a triangular base has a volume of 432 cubic feet.

The height of the prism is 8.

The triangle base has a base of 12 feet.

Question asked:

The height of the triangular base of the prism = ?

solution:

Volume of triangular prism = $Area of triangle \times height$

$432 = Area of triangle \times8$

Dividing both side by 8

$54 = Area of triangle$

$54 =$ $\frac{1}{2} \times base \times height$

$54 = \frac{1}{2} \times12\times height\\54 = \frac{12}{2} \times height$

Multiplying both side by 2

$108 = 12 \times height$

Dividing both side by 12

$9 = height$

Thus, height of the triangular base of the prism is 9

Please actually answer this it has a good amount of points!

Vanyuwa [196]

The answer is D, "No, because two points with the same x-value have different y-values."

Essentially, there cannot be more than one point on the same x-line. Point (2, 11) and point (2, 2) are on the same x-line, which is 2.

Hope this helps!

Which equation can be used to solve for m∠1? m∠1 = One-half(a – b) m∠1 = One-half(a + b) m∠1 = One-half(c – d) m∠1 = One-half(c

Artemon [7]

Answer:

$m\angle 1=\frac{1}{2}(arc\ a+arc\ b)$

Step-by-step explanation:

The picture of the question in the attached figure

we know that

The measure of the<u><em> interior angle</em></u> is the semi-sum of the arches that comprise it and its opposite.

$m\angle 1=\frac{1}{2}(arc\ a+arc\ b)$

roys car gets an average gas mileage of 29mi/gal. Roy starts his trip with 12 gal of gas.How many gallons of gas are left after

kolezko [41]

The answer is 208. The equation to get this is m=29g-140 where m is miles and g is the gallons. Plug 12 in for g and solve for m. 29 * 12 = 348, 348-140 = 208. Therefore, m=208.
