Answer:
35%
Step-by-step explanation:
The price it cost the site to buy the grills was $580 but they were selling them for $783. So for each grill, they get a profit of $203. (783-580=203).
35% of $580 is 203 which adds up to $783
So therefore the markup rate is 35% I hope this helps!
Answer:
x = 9
Step-by-step explanation:
Solve for x:
x^2 - 18 x + 81 = 0
Write the left hand side as a square:
(x - 9)^2 = 0
Take the square root of both sides:
x - 9 = 0
Add 9 to both sides:
Answer: x = 9
<span>A.(0,8)
B.(-1,8)
C.(1.5,10)
D.(2,16)
Simply substitute the value of x to get the value of y.
y = 8x
(0,8) y = 8(0) ; y = 0
(-1,8) y = 8(-1) ; y = -8
(1.5,10) y = 8(1.5) ; y = 12
(2,16) y = 8(2) ; y = 16
The correct ordered pair is D. (2,16)</span>
Answer:
1. The tetrahedron has 4 vertices, 6 edges and 4 faces. Then V-E+F=4-6+4=2
2. The cube has 8 vertices, 12 edges and 6 faces. Then V-E+F=8-12+6=2
3. The octahedron has 6 vertices, 12 edges and 8 faces. Then V-E+F=6-12+8=2
4. The icosahedron has 12 vertices, 30 edges and 20 faces. Then V-E+F=12-30+20=2
5. The dodecahedron has 20 vertices, 30 edges and 12 faces. Then V-E+F=20-30+12=2.
