JulsSmile [24]
To answer this question, we would have to use algebra.

Let the unknown number be A.

Now, as per the question, we have the equation -> 
2A - 7 > 5 + A
==> 2A - A > 5+7

Sal was tired of waiting for Amir to show up at their meeting place, so he started running at an average speed of 4.5 mph withou
sergiy2304 [10]
A=-.25+6.7t, s=.75+4.5t  when Amir catches up a=s so:

-.25+6.7t=.75+4.5t  add .25 to both sides

6.7t=1+4.5t subtract 4.5t from both sides

2.2t=1  divide both sides by 2.2

t=10/22 hr

t≈0.45 hr (to nearest hundredth)

Colton has a stone paperweight composed of a triangular pyramid on top of a triangular prism with the dimensions shown below. Us
Eva8 [605]

The area of the base would be found using the area of a triangle formula which is 1/2 x base x height.

The base and height are the two sides perpendicular to each other, which are both 5 inches.

The area of the base = 1/2 x 5 x 5 = 12.5 square inches.

The volume of the triangular prism is the area of the base times the height, which is 4 inches.

Volume of the triangular prism is 12.5 x 4 = 50 cubic inches.

Volume of the triangular prism is 1/3 x area of base x height, which is 7:

Volume of the triangular prism = 1/3 x 12.5 x 7 = 29.17 cubic inches.

Total volume = 29.17 + 50 = 79.17 cubic inches.
