True
It won’t be a Prefect Triangle but it still is one
(sorry my drawing is bad)
Given that the die-cast plane is scaled at 1 inch to 1 foot. This means that for each foot of the actual plane, the toy is 1 inch.
Therefore, the dimensions of the actual plane is given by 1 x 6.5 inches wide by 1 x 8.5 inches long = 6.5 inches wide by 8.5 inches long.
Answer:
The number of seedlings the three boys planted together is 560 seedlings
Step-by-step explanation:
The possible information in the question are;
Percentage of the seedlings planted by Ali = 40%
Percentage of the seedling planted by Ben = 45%
The percentage of the seedling planted by Cliff = The rest of the seedling
The number of seedling planted by Cliff = 84 siblings
Therefore, the percentage of the seedling planted by Cliff = 100% - 45% - 40% = 15%
Given that Cliff planted 15% of the seedlings, we have;
15% of seedlings Cliff planted = 84
Let X = the total number of seedlings
15/100 × X = 0.15×X = 84
X = 84/0.15 = 560
The total number of seedlings = The number of seedlings the three boys planted together = 560 seedlings.
Answer:
Step-by-step explanation:
<u>Given line:</u>
Perpendicular lines have negative-reciprocal slopes.
<u>We will have a line:</u>
<u>Use the coordinates of the given point to find the value of b:</u>
- -1 = -3(5) + b
- -1 = - 15 + b
- b = 14
<u>So the line is:</u>
Let's find the base first.
9*24*1/2 = 9*12 = 108
Now we multiply that by 2, as there are 2 triangles.
108*2 = 216
We'll find the 15 by 20 side next.
15 * 20 = 300.
Multiply that by 2, as there are 2 rectangles of those dimensions.
300*2 = 600
The last side is the 24 by 20 side.
24*20 is 480.
There's only one of those rectangles, so we won't multiply it by 2.
Now, we'll add all of our areas together.
216+600+480 = 1296.
Therefore the answer is A, 1296 in^2.
Hope that helps! :)
