Answer:

Step-by-step explanation:

No, the entire population of Turks and Caicos would not be able to fit on the football field. The total area of the football field is 6,480 square yards, which is equivalent to 13,728 square feet. Since each person takes up 2 square feet, this means that only 6,864 people could fit on the field. Therefore, the population of Turks and Caicos is more than double the amount of people that could fit on the football field.

Answer:

flagpole is sqrt(7h)

Step-by-step explanation:

We can use similar triangles to find the height of the flagpole.

Since Justin can see the top of the pole in the mirror, we can assume that the mirror and the ground form a right angle and the flagpole, mirror and Justin form a right triangle.

We can use the concept of similar triangles to find the height of the flagpole.

Let h be the height of the flagpole.

We can set up a proportion:

(7+h)/h = h/(7)

Cross-multiply and solve for h:

7h + h^2 = 7h

h^2 = 7*h - 7h

h^2 = 7h

h = sqrt(7h)

So the height of the flagpole is sqrt(7h)

It is worth noting that this answer is a square root of a variable and not a numerical value, thus we can't find an exact value of the height of the flagpole.

The percentage discount that Cyprian was allowed altogether was 8.21%.

The percentage discount is a portion of the sales price that reduces the amount the purchaser or customer pays for their purchase.

Percentages are ratios of a value or variable compared to another or the whole matter.

We express Percentages as the quotients of the division operations multiplied by 100.

In this situation, the overall percentage discount is worked out step by step as follows:

Discount on goods worth Sh. 800 = 11%

= Sh. 88 (Sh. 800 x 11%)

Discount on goods worth Sh. 17,000 = 8.6%

= Sh. 1,462

The total value of goods = Sh. 17,800 (Sh. 800 + Sh. 17,000)

Percentage discount = 8.21% (Sh. 1,462/Sh. 17,800 x 100)

Thus, overall, the total discount based on the full value of goods Cyprian bought was 8.21%.

We have to given that;

In trapezoid PQRS,

PQ is parallel to SR, and diagonal PR is drawn.

And, SP = SR, SRP = 50°, and PRQ = 85°

The domain of a function is the set that contains all the possible input values for the function.

The function in this problem is defined as follows:

H(x) = (x + 2)/(x² + 4x + 4).

The function is a fractional function, meaning that the denominator cannot assume a value of zero.

Hence the values of x that are not in the domain of the function are obtained as follows:

Step-by-step explanation:

Given that the second term of the sequence is 5, and that we are to multiply the previous term by 3 and subtract 4, we can use that as a recursive formula to find the other terms of the sequence.

The first term of the sequence is:

5*3-4 = 11

The third term of the sequence is:

53-4=11

113-4=29

The fourth term of the sequence is:

53-4=11

113-4=29

29*3-4=83

The difference between the first and fourth terms of the sequence is:

83-11 = 72

The amount invested in the two different bank accounts which has a simple interest of $ 560 is $ 2000 and $ 4000 respectively

Simple interest is a method of calculating interest that ignores the impact of compounding. While interest frequently compounds throughout the course of a loan's set periods, simple interest does not. Simple interest is calculated by multiplying the principal amount by the interest rate, times the number of periods.

Simple Interest = ( Principal Amount x Rate x Time Period ) / 100

Given data ,

Let the simple interest be represented as SI

The value of SI = $ 560

Now , the total amount A = $ 6000

Let the first bank account be A

Let the second bank account be B

The amount invested in the bank account A be = P

The amount invested in the bank account B be = ( 6000 - P )

The rate of interest of bank account A = 8 %

The rate of interest of bank account B = 10 %

Now ,

The SI of bank account A = ( Principal Amount x Rate x Time Period ) / 100

Substituting the values in the equation , we get

The SI of bank account A = ( P x 8 x 1 ) / 100

The SI of bank account A = 8P/100

And ,

The SI of bank account A = ( Principal Amount x Rate x Time Period ) / 100

Substituting the values in the equation , we get

The SI of bank account A = [ ( 6000 - P ) x 10 x 1 ] / 100

The SI of bank account A = ( 60000 - 10P ) /100

And , the total SI = $ 560

So ,

8P/100 +  ( 60000 - 10P ) /100 = 560

Multiply by 100 on both sides of the equation , we get

8P + 60000 - 10P = 56000

On simplifying the equation , we get

-2P = -4000

Divide by -2 on both sides of the equation , we get

P = $ 4000

So , the amount invested in bank account A = $ 4000

And , the amount invested in bank account B = $ 2000

Hence , the amount invested is $ 4000 and $ 2000 respectively

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

The expression for the perimeter of the right triangle with hypotenuse 2p + 8 and base p - 5 is: perimeter = (p - 5) + sqrt((2p + 8)^2 - (p - 5)^2) + (2p + 8)

What is triangle ?

Triangle can be defined in which it consists of three sides, three angles and sum of three angles is always 180 degrees.

In a right triangle, the hypotenuse (the longest side) is opposite the right angle, and the other two sides are called the legs. In this case, the hypotenuse is 2p + 8 and one of the legs (the base) is p - 5.

To find the third side (the other leg), we can use the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the legs. In other words:

(hypotenuse)^2 = (leg 1)^2 + (leg 2)^2

Substituting the given values, we get:

(2p + 8)^2 = (p - 5)^2 + (leg 2)^2

Simplifying and solving for leg 2, we get:

leg 2 = sqrt((2p + 8)^2 - (p - 5)^2)

Now we can use the perimeter formula, which is the sum of the lengths of all the sides of the triangle. In this case, the perimeter of the triangle is:

perimeter = (leg 1) + (leg 2) + (hypotenuse)

Substituting the given values and the expression we found for leg 2, we get:

perimeter = (p - 5) + sqrt((2p + 8)^2 - (p - 5)^2) + (2p + 8)

Therefore, the expression for the perimeter of the right triangle with hypotenuse 2p + 8 and base p - 5 is: perimeter = (p - 5) + sqrt((2p + 8)^2 - (p - 5)^2) + (2p + 8)
