What is the volume of the composite figure?

Sladkaya [172]

Answer:

748 in^3.

Step-by-step explanation:

This consists of a triangular prism and a rectangular cuboid .

Volume of the prism = .1/2 * 8 *11 * 17 = 748 in^3

Volume of the cuboid = 5*8*17 = 680 in^3

Therefore the volume of the whole figure

= 680 + 748 = 1428 in^3.

Marcel and Floyd are playing games at an arcade. Marcel has $8.25 and is only playing $0.25 games. Floyd has $9.75 and is only p

EleoNora [17]

Answer:

3 games each

Step-by-step explanation:

because $0.75 is 3 times $0.25

Marcel: 0 plays= $8.25, 1 play=$8, 2 plays= $7.75, 3 plays= $7.5

Floyd : 0 plays= $9.75 1 play =$9.00 , 2 plays= $8.25, 3 plays = $7.5

not sure if this is the answer ???

A circle centered at the origin contains the point

valentina_108 [34]

Answer:

Yes, the distance from the origin to the point (8,√17) is 9 units.

Step-by-step explanation:

The equation of a circle centered at the origin with radius , r has equation:

${x}^{2} + {y}^{2} = {r}^{2}$

Since the circle passes through (0,-9), the radius is 9 units because (0,-9) is 9 units from the origin.

We substitute the radius to get:

${x}^{2} + {y}^{2} = {9}^{2}$

${x}^{2} + {y}^{2} = 81$

If (8,√17) lies on this circle, then it must satisfy this equation:

${8}^{2} + { (\sqrt{17} )}^{2} = 64 + 17 = 81$

This is True.

This means the distance from (8,√17) is 9 units from the origin.
