Solving for (b): In this case, n - 3
Substitute 3 for n in
<em>7.5 gallon of gas left</em>
Answer:
If I am correct, I think the surface area is 448.
Step-by-step explanation:
First start by finding the area of all the sides
Front side. 12 x 10 = 120
2 triangle sides: 8 x 10 = 80, 80 x 2 = 160
Bottom side: 6 x 12 = 72
Back side: 8 x 12 = 96
Then add up the surface area
120 + 160 + 72 + 96 = 448
Btw I don't know if I am correct, but I think this is the way you find surface area.
Yes you are correct good job
Answer:
No, these triangles cannot lie on the same line.
Step-by-step explanation:
Step-by-step explanation: For two triangles to lie on the same line they must have the same slope. slopes are negative because the triangles are leaning to the left.
10 times as many as a number is 10 × the number.
10 times as many as 1 ten is 10 × 10 = 100
10 times as many as 1 hundred is 10 × 100 = 1000
Therefore, 10 times as many as 1 hundred is 10 hundreds or
10 times as many as 1 hundred is one thousand.
