The scale factor of the dilation of the square is (b) 18 : 1

To find the scale factor, we need to determine how many times the length of the original square was multiplied to obtain the length of the new square.

The length of the original square is 4.5 meters, and the length of the new square is 81 meters.

Therefore, we need to divide the length of the new square by the length of the original square to find the scale factor:

81 meters ÷ 4.5 meters = 18

Step-by-step explanation:

1.Band A: Cost = $500

Band B: Cost $350 + $1.50x

2. The caterer's fixed cost is $150 and the rate per student served is $6.

3.Cost per ticket $12.50

4.we can buy at most 3 bouquets of roses.

What are linear equations?

The first-degree equations are linear equations. The straight line's equation can be found here. ax+by+c=0 is the most common form of a linear equation, where a and b are zeros.

Part 1:

Let x be the number of students.

Band A: Cost = $500

Band B: Cost $350 +$1.50x

The system of equations representing the cost of the two bands is:

CostA = 500

CostB = 350+ 1.5x

Part 2:

Let F be the fixed cost and R be the rate per student served.

From the given information, we can write two equations:

50R + F = 450

150R + F = 1050

Subtracting the first equation from the second, we

get:

100R = 600

Therefore, R = 6.

Substituting R in the first equation, we get:

50(6)+F450

Therefore, F = 150.

So, the caterer's fixed cost is $150 and the rate per student served is $6.

Part 3:

For 100 students:

CostA 500

CostB = 350+ 1.5(100) 500

Both bands have the same cost, but Band A has a lower variable cost.

So, we should choose Band A.

Total cost for 100 students = 500 + 150+ 6(100) =

$1250

Cost per ticket = Total cost / Number of students = 1250/100 = $12.50

For 200 students:

CostA = 500

CostB = 350+ 1.5(200) = 650

Band A still has a lower cost, so we should choose Band A.

Total cost for 200 students 500+ 150 + 6(200) = $1850

Cost per ticket = Total cost / Number of students =

1850/200 $9.25

Part 4:

Let D be the number of bouquets of daisies and R be the number of bouquets of roses.

The cost of daisies is $25 per bouquet and the cost of roses is $35 per bouquet. We want to spend no more than $500, so we can write:

25D +35R < 500

If we buy 15 bouquets of daisies, then we can spend at most $425 on roses:

25(15) + 35Rs 500

375 +35R ≤ 500

35R ≤ 125

If we buy 15 bouquets of daisies, then we can.

Mathematics College spend at most $425 on roses:

25(15)+35R ≤ 500

375 +35R≤ 500

35R ≤ 125

R≤ 3.57

So, we can buy at most 3 bouquets of roses.

the radius of the track is approximately 420.38 feet.

Why is it?

The circumference of the circular track is 0.5 miles or 0.5 × 5280 = 2640 feet.

The formula for the circumference of a circle is C = 2πr, where C is the circumference and r is the radius.

Therefore, 2640 = 2 × 3.14 × r

Simplifying the equation: 2640 = 6.28r

Dividing both sides by 6.28: r ≈ 420.38 feet

Therefore, the radius of the track is approximately 420.38 feet.

Circumference is the distance around the edge of a circle or any other curved, circular object. It is also the perimeter of the circle. It is calculated by multiplying the diameter of the circle by pi (π), which is a mathematical constant that is approximately equal to 3.14.

Answer:

17.2 meters

Step-by-step explanation:

We can use the tangent function to solve this problem. Let's denote the height of the tree as h. Then we have the following:

tan(51°) = h / distance from the tree to the end of the shadow

We can find the distance from the tree to the end of the shadow by using the length of the shadow and the angle of elevation of the sun. Since the shadow is 21 meters long, and the angle of elevation of the sun is 51°, we can use the following trigonometric relationship:

tan(51°) = h / distance from the tree to the end of the shadow

tan(51°) = h / x (where x is the distance from the tree to the end of the shadow)

To find x, we can use the following trigonometric relationship:

tan(39°) = h / x (where 39° is the complementary angle to 51°)

We can solve for x by rearranging this equation as follows:

x = h / tan(39°)

Substituting this expression for x into the first equation, we have:

tan(51°) = h / (h / tan(39°))

Simplifying this equation, we get:

h = (21 m) * tan(51°) / tan(39°)

Using a calculator, we find h to be the following:

h = 17.2 meters

Therefore, the height of the tree is approximately 17.2 meters.

It would take the giant tortoise approximately 21.43 hours to travel 3 miles at a rate of 0.14 miles per hour.

What is distance?

Distance is the measure of how far apart two objects or locations are from each other. It is usually measured in units such as meters, kilometers, miles, or feet. Distance is a scalar quantity, meaning it has only magnitude and no direction.

We can use the formula:

time = distance ÷ speed

where "distance" is the total distance to be traveled and "speed" is the rate of travel.

In this case, the distance is 3 miles and the speed is 0.14 miles per hour. So we can substitute these values into the formula and solve for "time":

time = 3 miles ÷ 0.14 miles per hour

time ≈ 21.43 hours

Therefore, it would take the giant tortoise approximately 21.43 hours to travel 3 miles at a rate of 0.14 miles per hour.

Answer: To find the premium for insuring the goods, we need to determine the total amount of insurance that is needed and then calculate the cost of the insurance based on the given rate.

The total amount of insurance needed is equal to the value of the goods in transit, which is K95 480.

To determine the cost of the insurance, we can use the given rate of K682 for every K27 200 worth of goods. We can set up a proportion:

(K682 / K27 200) = (premium / K95 480)

To solve for the premium, we can cross-multiply and simplify:

K682 * K95 480 = K27 200 * premium

premium = (K682 * K95 480) / K27 200

premium = K1 897.12

Therefore, the premium for insuring the goods is K1 897.12.

The equation of circle with endpoints at  (-3, 0) and (3, 0) is x² + y² = 9

The end points (-3, 0) and (3, 0) represent the endpoints of a diameter of the circle. The center of the circle is the midpoint of this diameter. We can find the midpoint of the diameter by averaging the x-coordinates and the y-coordinates of the endpoints:

Midpoint = ((-3 + 3)/2, (0 + 0)/2) = (0, 0)

So the center of the circle is at the point (0, 0). The radius of the circle is half the length of the diameter, which is:

Radius = 1/2 * distance between (-3, 0) and (3, 0)

= 1/2 * 6

= 3

Therefore, the equation of the circle with endpoints at (-3, 0) and (3, 0) is:

(x - 0)² + (y - 0)² = 3²

Answer:

the value of T that satisfies the equation 644 204 = 400 000(1+10%) is approximately 6.45.

Step-by-step explanation:

We can simplify the equation 644 204 = 400 000(1+10%) by first simplifying the percentage term on the right-hand side:

10% of 400 000 is equal to 0.1 × 400 000 = 40 000.

So the equation becomes:

644 204 = 400 000(1 + 0.1 × 1)

Now, we can use logarithms to solve for T:

T = log(base 1.1)(644204/400000)

Using a calculator, we can evaluate the right-hand side to be approximately 0.2, so:

T = log(base 1.1)(1.61051)

Using the change of base formula, we can rewrite this as:

T = ln(1.61051) / ln(1.1)

Evaluating the natural logarithms using a calculator, we get:

T ≈ 6.45

Step-by-step explanation:

To find the amount of oxygen needed in the outer tank, we need to first find the volume of the space between the two tanks. This space is a rectangular prism with length 20 feet, width 8 feet, and height 6 feet, but with a rectangular prism removed from the center. The removed prism has length 5 feet, width 4 feet, and height 3 feet.

The volume of the rectangular prism between the two tanks is:

V = (20 x 8 x 6) - (5 x 4 x 3)

V = 960 - 60

V = 900 cubic feet

To find the amount of oxygen needed to fill this space with a density of 0.0827 pounds per cubic foot, we can multiply the volume by the density:

m = V x d

m = 900 x 0.0827

m ≈ 74.43 pounds
