We know that,

→ Area of circle = πr²

→ Area of circle = π × (6)²

→ Area of circle = π × 36

→ Area of circle = 36π

What is the area of a circle with a radius of 6 inches?

We know,

Radius = 6 inches (Given)

So, Area of circle = π(6)² = 36π in²

The area of a circle with a radius of 6 inches is 36π in².

Hence, option (c) 36π in² is correct. [Answer]

The required confidence interval is (5.5<<5.7) for the mean number of dresses purchased each year.

As per the question, the given data as

[tex]\bar{x}[/tex] = 5.6

σ = 1.3

n = 650

The Z-critical value at the 95% confidence level is 1.960.

To determine the 99% confidence interval for the mean number of dresses purchased each year.

95% CI = [tex]\bar{x}[/tex]  ± Z(Cr)(s/√n)

⇒ -5.6 ± 1.960(1.3/√650)

⇒ 5.6±0.100

⇒ (5.500,5.700)

Round to near 1 decimal place

⇒ (5.5,5.7)

Therefore, the required confidence interval is (5.5<<5.7)

Yes, halving the denominator and doubling the numerator gives the same results so she is correct.

In such a fraction, the value that appears above the horizontal line is referred to as the numerator.

It shows how many parts have been taken out of the whole. The numerical number that comes before the sum of all the factors is the denominator of a fraction.

Let's consider a multiplication a × b

If we do half of a and double of b

Then,

a/2 × 2b = a × b

Again,

(a/2)/2 × 2(2b) = a × b

So it will remain the same.

So similarly  8 x 90 will also remain the same.

Hence "Yes, halving the denominator and doubling the numerator gives the same results so she is correct".

Answer:

x = 11

Step-by-step explanation:

ΔLKM is an equilateral because a triangle with all 3 sides that are congruent is an equilateral triangle.

Angles in an equilateral triangle are all 60°.

Thus, ∠L = 60°.

=> 3x + 27 = 60

=> 3x = 33

=> x = 11

[tex]x=11[/tex]

Step-by-step explanation:

[tex]∠L=(3x+27)°[/tex]

Value of x.

[tex]∠L= ∠K= ∠M=(3x+27)°[/tex]

[All sides of triangle are equal]

[tex]∠L+ ∠K+ ∠M= 180°[/tex]

[Sum of all of triangle is 180°]

Answer:

7)Bagel costs $3.5 and muffin cost $1.25

8) Ticket is $9 while snacks are $2

9) Correct because left hand side is zero

10) Correct because they both have same slope and same y-intercept

Step-by-step explanation:

7) Let bagel be x and muffin be y.

Thus;

For Aaron;

x + 3y = 7.25 - - - (1)

For bee;

x + 2y = 6 - - - (2)

Subtract eq 2 from eq 1 to get;

y = 1.25

Put 1.25 for y in eq 2;

x + 2(1.25) = 6

x + 2.5 = 6

x = 6 - 2.5

x = 3.5

Bagel costs $3.5 and muffin cost $1.25

8) Let movie ticket be x and snacks be y.

Thus;

2x + 3y = 24 - - - (1)

3x + 4y = 35 - - - (2)

Multiply eq(1) by 3 and eq(2) by 2 to get;

6x + 9y = 72 - - - (3)

6x + 8y = 70 - - - (4)

Subtract eq 4 from eq 3 to get;

y = 2

Put 2 for y in eq 3;

6x + 9(2) = 72

6x + 18 = 72

6x = 72 - 18

6x = 54

x = 54/6

x = 9

Ticket is $9 while snacks are $2

9) using elimination, subtract eq 1 from eq 2, we will see that the entire left hand side is equal to zero.

Thus, no solution exists because we can't isolate the variable to get an answer.

10) The answer is correct because for a system of 2 simultaneous equations to have infinite solutions, they both have to have the same y-intercept and also same slope.

In this case, their y-intercept which is when x is 0 is;

3(0) + y = 9

y = 9

Their slope is also the same equal to 3.

Answer: 408

Step-by-step explanation:

The present worth of Rs 2040 is due 4 years hence reckoning interest at 5% per annum will be Rs 2448.

Simple interest is a way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific duration of time.

Simple interest has a constant principal amount, as opposed to compound interest, which multiplies the interest from the principal of previous years to calculate the interest of the subsequent year.

Given,

Principle amount =  Rs 2040

Time period = 4 years

Rate of interest = 5 %

Simple interest = PRT/100

Simple interest = 2040 × 5 × 4/100 = Rs408

Present worth =  Principle amount + Interest

Present worth = 2040 + 408

Present worth = Rs 2448.

Hence present worth of the amount of Rs2040 in 4 years will be Rs 2448.

Answer:

443.736759 day

Step-by-step explanation:

To convert a seconds to days, divide the time by the conversion ratio.

So.....

One day is equal to 86,400 seconds, you can use this formula to convert:

 days = seconds ÷ 86,400

The time in days is equal to the seconds divided by 86,400.

Example: Convert 50,000 seconds to days (use the formula above)

50,000 sec = (50,000 ÷ 86,400) = 0.578704 day

Answer:

30 ft is the answer.

Step-by-step explanation:

a = 24 ft

b = 18 ft

c = ?

According to the Pythagoras theorem,

a² + b² = c²

24² + 18² = c²

576 + 324 = c²

c² = 900

c = 30 ft

∴ The opposite corners of the living room are 30 ft apart.
