Answer:
SQUARE= 108 blocks
CIRCLE= 97.97
# OF BUNDLES= 2.05, 3
Step-by-step explanation:
square- find perimeter
- 22.5 x 4= 90ft
- 90ft/10inches
- convert 90 ft to inches> 90 x 12= 1080/10= 108
circle-
- find the circumference= c=2piR
- 2x3.14x13=81.64
- 81.64ft to in = 979.68/10
- =97 rounded
number of bundles = 205/100 =2.05, so 3
Answer:
<em>Choice B. 16 feet.</em>
<em>The height of the tree is 16 ft</em>
Step-by-step explanation:
<u>Similar Triangles</u>
Similar triangles have their corresponding side lengths proportional by a fixed scale factor.
We are given the drawings of a tree and a wall and it's assumed both triangles are similar. We need to find the scale factor and find the height of the tree.
Comparing the corresponding distances from the viewer to the base of the tree and the base of the wall, we can calculate the scale factor as 24/6=4.
Applying the same factor to the height of the model, we get the height of the tree is 4*4 = 16 ft.
Choice B. 16 feet
The height of the tree is 16 ft
Answer:
Step-by-step explanation:
1) The center lies on the vertical line x = -5 and the the circle is tangent to (touches in one place only) the y-axis. Thus, the radius is 5.
2) Starting with (x - h)^2 + (y - k)^2 = r^2 and comparing this to the given
(x - 4)^2 + (y + 3)^2 = 6^2
we see that h = 4, k = -3 and r = 6. The center is at (4, -3) and the radius is 6.
3) Notice that A and B have the same x-coordinate, x = 15. The center of the circle is thus (15, -2), where that -2 is the halfway point between the two given points in the vertical direction. Arbitrarily choose A(15, 4) as one point on the circle. Then the equation of this circle is
(x - 4)^2 + (y + 3)^2 = r^2 = 6^2, where the 6 is one half of the vertical distance between A(15, 4) and B(15, -8) (which is 12).
Answer:
13.5
Step-by-step explanation:
12/4=3
9/3=3
4.5x3=13.5
2 + 2 equals to 4
You can do it on the calculator too.
