Answer:
a) 540°
b) 720°
c) 900°
d) 1440°
Step-by-step explanation:
The total measure of internal angles of a convex polygon is given by the formula ...
sum of angles = 180°(n -2) . . . . for an n-sided polygon
So, you count the sides, subtract 2, and multiply that result by 180°.
__
a) 180°(5 -2) = 540°
b) 180°(6 -2) = 720°
c) 180°(7 -2) = 900°
d) 180°(10 -2) = 1440°
Answer : 76
Step by Step Explanation:
Substitute for "r" and solve for "t":
5(4t+8) + 2t = 414
22t + 40 = 414
22t = 374
t = 17 (# of tulips sold)
---
r = 4*17+8 = 76 (# of roses sold)

Answer: 21.69 g
Step-by-step explanation:
Find the amount of compound produced when 300 mg of catalyst is added
<u>Given:</u>
Equation: A = 0.06c + 3.16
c = 300 mg
Substituting c = 300 into the equation and solving for A
A = 0.06 * 300 +3.69
A = 18 + 3.69
A = 21.69
Therefore 21.69 g of compound will be produced
