Answer:
48 Units
Step-by-step explanation:
Use the Pythagorean theorem to make two right triangles.
Ex= Base is cut in half to make two 9 unit bases
Then count the units from the half point.
Ex= 12 units long
Then use Pythagorean theorem to find one side of the 9-12 right triangle
Ex= 9^2+12^2=c^2
After finding that c=15 units, add all the sides back together
Ex= 18+15+15=48
Answer:
multiply the givens. use a calculator
Answer:
1) 4
2) 1.5
3) 8
4) 1
5) 5
6) 9
Step-by-step explanation:
<h3>
1)</h3><h3>
√16</h3>
= √(4x4)
= √(4)²
<h3>= 4</h3>
<h3>
2)</h3><h3>
√2.25</h3>
= √(9/4)
= √(3x3)/(2x2)
= √(3)²/(2)²
= 3/2
<h3>= 1.5</h3>
<h3>3)</h3><h3>6² ÷ 9 x 2 </h3>
= 36 ÷ 9 x 2
= 36 x 1/9 x 2
= 36/9 x 2
= 12/3 x 2
= 4 x 2
<h3>= 8</h3>
<h3>4)</h3><h3>12-2 / 6+4</h3>
= 10/10
<h3>= 1</h3><h3 /><h3>5)</h3><h3>√(16+9)</h3>
= √(25)
= √(5x5)
= √(5)²
<h3>= 5</h3><h3 /><h3>6)</h3><h3>63 ÷ 3² + |2|</h3>
= 63 ÷ 9 + |2|
= 63/9 + |2|
= 21/3 + |2|
= 7 + |2|
<h3>= 9</h3>
Answer:
12.99km
Step-by-step explanation:
Using the formula
C=2(pi)(r)
Answer:
(x + 2/3)^2 + (y + 3/4)^2 = 5^2 (or 25).
Step-by-step explanation:
Start with the general equation of a circle with center at (h, k) and radius r:
(x - h)^2 + (y - k)^2 = r^2
Substitute -2/3 for h and -3/4 for k, and also 5 for r:
(x - [-2/3])^2 + (y - [-3/4])^2 = 5^2, or
(x + 2/3)^2 + (y + 3/4)^2 = 5^2 (or 25).
