I believe it would be 12.16
At the same time, the sun casts a shadow on the girl and tree creating two similar right triangles. You can use a ratio of girl's height to her shadow will be the same as the tree's height to it's shadow.
5 / 2.5 = T / 14.5
2 = T / 14.5
2 * 14.5 = T
29 ft = Tree
To solve this equation (correct me if i'm wrong), you could first multiply the bottom equation by 3, to get 15y. After that, we get -4x-15y=-17 and -3x + 15y=-39, and if we add the 2 equations up, on top of each other, we get -7x=-56, and we can conclude that x=8, and with substitution (-32 - 15y = -17), we know that y=(-1)
Here's what I mean by on-top
-4x-15y=-17
-3x + 15y=-39
-7x=-56
Per gallon means you multiply for each gallon.
Please mark brainliest answer :^)
Answer:
1586cm
Step-by-step explanation:
The answer is 1586cm because.....
- Step one, we have two shapes here we need to figure out the volume of the smaller rectangle. so we have the width of 6 the height of 2 and now we need to find the length of the smaller rectangle. To do so it is the same length as the other rectangle so we will replace the missing length with 13 cm since that is what its length is. Now we multiply 6x2x13=156cm
- Step two now we find the Volume of the bigger rectangle. Since we have all of the sides, this part will be easy peasy. Multiply 5x13x22 to get 1430.
- Final step is add the two volumes together to get the total volume of this shape. Which is 1586 cm^2
- Hope i helped :)
