What is area?Area is the amount of space occupied by a two-dimensional figure. In other words, it is the quantity that measures the number of unit squares that cover the surface of a closed figure. The standard unit of area is square units which is generally represented as square inches, square feet, etc.
Here,
Area of a grid is 6×6 =36 cm²
a) Area of a tile with 1 cm x 1 cm is
1×1 =1 cm²
Number of tiles = 36/1 =36
b) Area of a tile with 2 cm x 2 cm is
2×2 =4 cm²
Number of tiles = 36/4 =9
a) Area of a tile with 3 cm x 3 cm is
3×3 =9 cm²
Number of tiles = 36/9 =4
Therefore, the number of tiles with the dimensions 3 cm x 3 cm are

What is the approximate area of the circle shown below?
Answer: C
Step-by-step explanation:
[tex]A=\pi (17)^2 \approx 908[/tex]
Answer:
Answer C is correct
Step-by-step explanation:
The formula to find the area of a circle is:
A = πr²
Here,
r => radius = 17cm
Let us find the area of the circle.
A = πr²
A = 3.14 × 17 × 17
A = 907.46 cm²
Approx. = 908 cm²
Question 25 Given that a: b = 8:5 and b: c = 3:4, find the ratio a: b: c Give your answer in its simplest form.
Answer:
24 : 15 : 20
Step-by-step explanation:
express ratios in fractional form and express b and c in terms of a
[tex]\frac{a}{b}[/tex] = [tex]\frac{8}{5}[/tex] ( cross- multiply )
8b = 5a ( divide both sides by 8 )
b = [tex]\frac{5}{8}[/tex] a
also
[tex]\frac{b}{c}[/tex] = [tex]\frac{3}{4}[/tex] ( cross- multiply )
3c = 4b ( divide both sides by 3 )
c = [tex]\frac{4}{3}[/tex] b = [tex]\frac{4}{3}[/tex] × [tex]\frac{5}{8}[/tex] a = [tex]\frac{5}{6}[/tex] a
Then
a : b : c
= a : [tex]\frac{5}{8}[/tex] a : [tex]\frac{5}{6}[/tex] a ( multiply each part by 24, the LCM of 8 and 6 )
= 24a : 15a : 20a ( divide each part by a )
= 24 : 15 : 20 ← in simplest form

I dont know how to find the end behavior of this. Please help
Answer:
The end behavior of the function is that it approaches positive infinity as x decreases to negative infinity, and it also approaches positive infinity as x approaches positive infinity.
Step-by-step explanation:
The end behavior of a function is what happens to the value of the function as x approaches negative infinity and as x approaches positive infinity.
Graphing the function is very helpful to visualize the end behavior.
Here, the graph has the shape of a V with the vertex on the x-axis going up in value on both sides forever.
The function here is f(x) = 3|x|.
Let's try a few values for x to get an idea.
We will deal with x approaching positive infinity first.
f(0) = 3|0| = 0
Let's get larger and larger values for x, approaching positive infinity.
f(10) = 3|10| = 30
f(10,000) = 3|10,000| = 30,000
f(1,000,000) = 3|1,000,000| = 3,000,000
As you can see, as x increases, the value of f(x) also increases. As x approaches positive infinity, f(x) also approaches positive infinity.
Now let's look at values of x approaching negative infinity.
f(0) = 3|0| = 0
Let's get smaller and smaller values for x, approaching negative infinity.
f(-10) = 3|-10| = 30
f(-10,000) = 3|-10,000| = 30,000
f(-1,000,000) = 3|-1,000,000| = 3,000,000
As you can see, as x decreases, the value of f(x) increases. As x approaches negative infinity, f(x) approaches positive infinity.
The end behavior of the function is that it approaches positive infinity as x decreases to negative infinity, and it also approaches positive infinity as x approaches positive infinity.

120 cm² is the surface area of the right triangular prism
How to find the surface area of a right triangular prism?The surface area of a right triangular prism can be determined using the formula below:
A = (S₁ + S₂ + h)L + bh (Check the attached image for the labeling)
Given: S₁ = 3 cm, S₂ = 5 cm, h = 4 cm, L = 6cm and b = 3 cm
Substitute these values into the formula:
A = (S₁ + S₂ + h)L + bh
A = (3 + 5 + 4)6 + 3(4)
A = (18)6 + 12
A = 120 cm²

Val's whole-house central air conditioner uses 3,500 watts when running. Val runs the AC 7 hours per summer day. Electricity costs (10 cents)/(1 kilowatt-hour). How much does Val's AC cost to run for a summer month of 30 days?
During 30 days of summer, Val will spend $ 73.5 on electricity from the use of his air conditioner.
How to find the value of x?Any of the following algebraic expressions should be used: addition, subtraction, multiplication, and division. Bring the variable to the left side, then move all of the other values to the right side to determine the value of x. For the outcome, simplify the values.
Since Val's air conditioner uses 3,500 watts when running, and that Val Utilizes it for 7 hours during summer days, spending 10 cents per kilowatt hour, estimating how much money Val will spend during a 30-day summer must be done the following calculation:
3,500 watts = 3.5 kilowatts
3.5 kilowatts per hour = 35 cents
35 cents × 7 hours = 245 cents per day
245 cents per day × 30 days = 7,350 cents per month
7,350/100 = X

Suppose that $6000 is placed in a savings account at an annual rate of 4%, compounded quarterly. Assuming that no withdrawals are made, how long will it take for the account to grow to $8670?
The time taken for the money to grow to $8670 at compound interest is approximately 9.24 years.
Given the amount of money that is the principal = $6000
Rate = 4% compounded quarterly.
Time = t
Amount = $8670
Now we know that the amount is calculated by the formula:
A = P(1+r/4)ⁿ
8670 = 6000(1+0.01)ⁿ
Hence
log 1.445 = n log 1.01
or, n = 36.99
Number of years = 36.99 / 4 = 9.24 years.
The interest that is added to a loan or deposit is referred to as compound interest. Compound interest is computed for a sum utilizing both the principal and interest already paid. The main distinction between compound interest and simple interest is this.
If we look at our bank statements, interest is usually credited to our account once a year. While the principle remains constant, the interest changes annually.
