Answer:
110 chairs.
Step-by-step explanation:
(9x6) + (8x7) First multiply 9x6 and 8x7.
(54) + (56) In the first parenthesis, we have 9 tables with 6 chairs each. We are going to add that to the second parenthesis with 7 tables and 8 chairs each.
= 110 There are 110 chairs.
Solution :
Given initial population = 300
Final population after 1 day = 800
Number of days = 6
∴ 
P(0) = 300 P(1) = 300
We need to find P(8).




When P(0) = 300

∴ c = 300
∴ 
When P(1) = 800


∴ k = 750

So, P(8) is

= 11,614
So the population becomes 11,614 after 8 days.
Solve for 1 variable
solve for x in second
add 2y to both sides
x=2y-5
sub 2y-5 for x in first equation
2(2y-5)-5y=-14
4y-10-5y=-14
-10-y=-14
add 10 to both sides
-y=-4
times -1
y=4
sub
x=2y-5
x=2(4)-5
x=8-5
x=3
x=3
y=4

By applying the Pythagorean Theorem and the Trigonometry ratio, CAH, the value of cos(M) = 4/5
<em><u>Recall:</u></em>
Trigonometry ratios, <em>SOH CAH TOA</em> can be applied to solve a right triangle.
- Pythagorean Theorem can also be applied which is: c² = b² + a², where c is the longest side (hypotenuse length).
<em><u>Given:</u></em>
ΔMNL is a right triangle
ML = 25
NL = 15
Find MN using the Pythagorean Theorem:
MN = √(ML² - NL²)
MN = √(25² - 15²)
MN = 20
To find the value of cos(M), apply the trigonometry ratio, CAH, which is:
cos ∅ = Adj/Hyp
∅ = M (reference angle)
Hypotenuse = ML = 25
Adjacent = MN = 20
cos(M) = 20/25
cos(M) = 4/5
