The tin game's surface area 177 inch².
Step-by-step explanation:
Step 1:
To calculate the triangular prism's surface area, we calculate the areas of all the 5 sides.
We divide the prism into 2 triangles and 3 rectangles, find the area individually and then sum them all up in order to determine the entire triangular prism's area.
Step 2:
There are two triangles with base lengths of 10 inches and heights of 8.7 inches. To calculate a triangle's area we multiply with the product of the base length and it's height.
Area of 1 triangle = inch².
Area of both triangles = Area of 1 triangle × 2 = = 87 inch².
Step 3:
There are three rectangles with a common length of 10 inches and a width of 3 inches.
Any rectangle's area is given by multiplying the rectangle's length with its width.
Area of the 1 rectangle = inch².
Area of 3 rectangles = inch².
Step 4:
The area of the entire triangular prism = inch².
X = cost of 1 sweat shirt
3x = 45
x = 15
5x = 5(15) = 75
It would cost $75. Hope this helps!
Answer:
3 tents hold 2 campers
Step-by-step explanation:
The given relations can be expressed as a single equation in the number of 2-camper tents.
__
Let x represent the number of 2-camper tents. Then the number of 4-camper tents is 6-x, and the total number of campers in tents is ...
2x +4(6 -x) = 18
-2x +24 = 18
-2x = -6 . . . . . . subtract 24
x = 3 . . . . . . . divide by -2
Exactly 3 tents hold 2 campers.
_____
<em>Additional comment</em>
The other 3 tents hold 4 campers.
Another way to consider this is to assume that all tents hold 2 campers, and then realize there are 18 -6×2 = 6 campers left over. If these are placed 2 per tent, then there will be 6/2 = 3 tents with 4 campers. The remaining 3 tents will have 2 campers.
