Answer:
a(9) = 150*(0.4)^8 = 0.098304
Step-by-step explanation:
This is a geometric sequence, because each new term is 0.4 times the previous term.
The general formula for a geometric sequence is a(n) = a(1)*r^(n - 1). Here, with a(1) = 150 and r = 0.4, we have:
a(n) = 150*(0.4)^(n - 1), and so
a(9) = 150*(0.4)^8 = 0.098304

The square is shown with a side length of 8 inches.
The area of a square is s^2, which can also be written as s x s, where a is the length of the side.
Area of the square would be 8 x 8 = 64 square inches.
The area of a circle is pi x r^2, where r is the radius. R is given as 3 inches.
The area of the circle is 3.14 x 3^2 = 28.26 square inches.
The shaded area is the square minus the circle.
The shaded area = 64 - 28.26 = 25.74 square inches.
The answer is 25.74 square inches.
Look at my explanation to know the answer clearly.
So, we're supposed to find the area of the shaded part.
In the problem, the shaded part is the square, and the side is 8 in.
Let's apply this formula, A = L · W or A². So, we can multiply the Length and Width to get the area.
The length is 8.
Since we don't have a width, we can use A². We can find 8 to the 2nd power to get the answer.
8 to the 2nd power is 64. How?
1. Break the exponent down.
8² ⇒ 8 × 8
2. Solve.
8 × 8 = 64
Hence, 64 is the answer. Hence, 64 is the answer. Now, we'll need to find the circumference of the circle.
The formula for that is 2 π r²
The radius is 3 in, so let's multiply 2 by 3² by 3.14.
3² × 3.14 = 28.26
Lastly, subtract 64 by 28.26.
64 - 28.25 = 25.74
Hence, your final answer is 25.74in.

here’s the graph
Answer:
0.6x - 12.88
Step-by-step explanation:
Start by distributing the values outside the quantities to the values inside the quantities.
0.4(-3.6-0.5x) + 0.8(1.9 + x)
-14.4 - 0.2x + 1.52 + 0.8x
Combine like terms

Using t and c as variables, we get
100c + 400t ≥ 5400
Simplified,
100(c + 4t) ≥ 5400
c + 4t ≥ 54
To find the minimum number of chairs that need to be sold, we evaluate using t = 0
c + 4(0) ≥ 54
c ≥ 54
To find the minimum number of tables that need to be sold, we evaluate using c = 0
(0) + 4t ≥ 54
4t ≥ 54
t ≥ 13.5 Since we can't purchase half a chair, we round up our result giving us t ≥ 14

Answer:
a) The addition property of equality
b) The division property of equality
Step-by-step explanation:
Here, we want to know the correct step to use
From the given question, to proceed;
All we have to do is to move the value that has a negative value on the left hand side to the right hand side
what accompanies this is the addition of the both terms, on the right hand side
After this, we now proceed to divide the sum by the coefficient of x
Thus, the correct choices are;
a) The addition property of equality
b) The division property of equality
During the annual black Friday sale,the OLX sold a price of ski boots at regular price of $245 at a discount of 40%the boots cost 96$, and expenses at 26% of the regular price, how much was the ski boots sold
Answer: $147
Step-by-step explanation:
The boots were sold at a 40% discount of the regular price of $245.
The price they were sold at is therefore:
= Price * ( 1 - discount)
= 245 * ( 1 - 40%)
= 245 * 60%
= $147
