The radius of the sphere is approximately 3.634 inches.

We have,

The formula for the volume of a sphere is:

V = (4/3)πr³

where V is the volume of the sphere and r is its radius.

We know that the volume of the sphere is 36π cubic inches.

Substituting this value into the formula, we get:

36π = (4/3)πr³

Multiplying both sides by 3/4π, we get:

r³ = (36π)/(3/4π) = 48

Taking the cube root of both sides.

r = (48)^(1/3)

r = 3.634 inches (rounded to three decimal places)

Therefore,

ii) The pressure on the ground by European hare is 0.15 N/cm².

b) The snowshoe hare is suited to living in snow because it has a larger surface area of feet.

a) The pressure on the ground can be calculated by dividing the force on the ground due to weight by the total surface area of the feet.

i) For the snowshoe hare, the pressure on the ground is:

Pressure = Force on ground / Total surface area of feet

Pressure = 14 N / 200 cm²

Pressure = 0.07 N/cm²

ii) For the European hare, the pressure on the ground is:

Pressure = Force on ground / Total surface area of feet

Pressure = 38 N / 250 cm²

Pressure = 0.15 N/cm²

b) The snowshoe hare is suited to living in snow because it has a larger surface area of feet than the European hare and exerts less pressure on the ground. This allows the snowshoe hare to move more easily over the snow without sinking.

Additionally, the snowshoe hare has fur on the soles of its feet, which provides additional insulation against the cold snow. These adaptations help the snowshoe hare survive in its snowy environment by allowing it to move and find food more easily.

Given statement "3-4 If you know the rise and run of a fable roof, you can calculate the rake length and area using slope factors." is true. Because the rise and run of a gable roof allows you to calculate the slope factor, which can then be used to calculate the rake length and area of the roof.

If you know the rise and run of a gable roof, you can calculate the rake length and area using slope factors. The slope factor is a ratio that relates the length of the roof to the height of the roof.

The slope factor is calculated by dividing the rise of the roof by the run of the roof. Once you have the slope factor, you can use it to calculate the rake length and area of the roof.

The rake length is the length of the diagonal edge of the roof, and it can be calculated by multiplying the slope factor by the run of the roof.

For example, if the run of the roof is 10 feet and the slope factor is 0.5 (which corresponds to a 6:12 pitch), then the rake length would be 5 feet (0.5 x 10).

The area of the roof can be calculated by multiplying the rake length by the width of the roof.

For example, if the width of the roof is 20 feet and the rake length is 5 feet, then the area of the roof would be 100 square feet.

Answer:

To write the equation of the line that represents Calvin’s spending on candy, we need to first find the slope and the y-intercept of the line.

We can use the two points given in the problem: (4, 28) and (10, 25)

Slope (m) = (y2 - y1) / (x2 - x1)

= (25 - 28) / (10 - 4)

= -3/6

= -1/2

The slope represents the rate at which Calvin is spending money on candy.

Now, we can use the point-slope form of the equation of a line to find the equation of the line.

y - y1 = m(x - x1)

y - 28 = (-1/2)(x - 4)

y - 28 = (-1/2)x + 2

y = (-1/2)x + 30

Therefore, the equation of the line that represents Calvin’s spending on candy is y = (-1/2)x + 30.

Answer: Equation that represents his spending on candy- y = (³⁄₁₀) x

X = number of candy

Step-by-step explanation:

y = money spend            x = number of candy

y = (m)x

cost for 10 pieces of candy = $(28 - 25) = $3

⇛ 3 = (m)x10 (x = 10 & y = 3)

⇛m=(³⁄₁₀)

Therefore the equation representing his spending on candy is

⇛ y = (³⁄₁₀) x

The length of the hypotenuse of a 45-45-90 triangle is √2x units.

To find the hypotenuse of a 45-45-90 triangle, we can use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the two shorter sides (legs) is equal to the square of the longest side (hypotenuse).

Let's denote the length of each leg of the triangle as "x". Since the triangle is isosceles, both legs are of equal length. Therefore, we can write:

Leg 1 = Leg 2 = x

To find the length of the hypotenuse (which we'll call "h"), we can use the Pythagorean theorem as follows:

x² + x² = h²

Simplifying this equation, we get:

2x² = h²

To solve for h, we need to take the square root of both sides of the equation:

√(2x²) = √(h²)

√2 * x = h

The measure of side ‘b’ in the given triangle ABC, with angle A measuring 54 degrees and angle C measuring 59 degrees and side BC measuring 11 is option-c:12.516, which is found using Sine-law.

In a scalene or oblique triangle (a non-right triangle), the law of sine describes the relationship between the sides and angles. Trigonometric laws such as the law of sines and law of cosines are crucial when "solving a triangle" by calculating the unknown angles or sides. The ratio of a triangle's side lengths to the sine of each of its opposite angles must be equal in order for the sine rule to apply. Triangle side length ratios to their corresponding opposite angles are connected by the law of sines. All three sides and the diagonal angles maintain the same ratio.

Given that ∠A= 54° ,∠C= 59° & side BC=a=11

We know that ∠A + ∠B + ∠C = 180°   {angle sum property}

Consider △ABC,

54° + 59° +  ∠B = 180°

113° +  ∠B = 180°

∠B = 180°- 113°

∠B = 67°

Applying Sine-Law,

[tex]\frac{A}{sin\ A} =\frac{B}{sin\ B} = \frac{C}{sin\ C}[/tex]

By using,

[tex]\frac{A}{sin\ A} =\frac{B}{sin\ B}[/tex] , we get:

[tex]\frac{11}{sin\ 54} =\frac{B}{sin\ 67}\\ \\\frac{11}{0.80901} =\frac{B}{0.92050} \\\\B=\frac{11}{0.80901} \times 0.92050[/tex]

Answer: 75%

Step-by-step explanation: 56 - 14 = 42. So, 42 people are not wearing red. 42/56 is .75, which is the decimal form for 75%. Also, if you simplify 42/56, you get 3/4 which is also 75%

The value of k is approximately 0.034. The projected Hispanic resident population in 2015 is approximately 73.9 million. The Hispanic resident population will reach 70 million in approximately 24.7 years after 2000, which corresponds to the year 2024.

To find k, we can use the fact that A = 35.3 million when t = 0 (i.e., in 2000), and A = 50.5 million when t = 10 (i.e., in 2010). Substituting these values into the exponential growth function, we get

35.3 = 35.3e^0k

50.5 = 35.3e^(10k)

Dividing the second equation by the first equation, we get

50.5/35.3 = e^(10k)

Taking the natural logarithm of both sides, we get

ln(50.5/35.3) = 10k

Solving for k, we get

k ≈ 0.034

Therefore, the exponential growth function is A = 35.3e^(0.034t).

To project the Hispanic resident population in 2015, we need to find A when t = 15 (i.e., 15 years after 2000). Substituting t = 15 into the exponential growth function, we get

A = 35.3e^(0.034*15) ≈ 73.9 million

Therefore, the projected Hispanic resident population in 2015 is approximately 73.9 million.

To find the year in which the Hispanic resident population reaches 70 million, we need to solve the exponential growth function for t when A = 70. Substituting A = 70 into the exponential growth function, we get

70 = 35.3e^(0.034t)

Dividing both sides by 35.3, we get

e^(0.034t) = 70/35.3

Taking the natural logarithm of both sides, we get

0.034t = ln(70/35.3)

Solving for t, we get

t ≈ 24.7

Therefore, the Hispanic resident population will reach 70 million in approximately 24.7 years after 2000, which corresponds to the year 2024.

The slope of the cathedral ceiling is 0.83.

To calculate the slope of the cathedral ceiling, we need to find the rise over the run. The rise is the difference in ceiling heights between the two points. The run is the horizontal distance between the two points.

From the problem statement, we know that the ceiling is 8 feet high at the west wall and 10.5 feet high three feet from the west wall. So the rise is:

rise = 10.5 - 8 = 2.5 feet

The run is the horizontal distance between the two points, which is:

run = 3 feet

Now we can calculate the slope:

The possible lengths of each side of the garden is given by the inequality relation 0 ≤ x ≤ 12

Given data ,

Let's assume that the square garden has sides of length x.

To surround the garden, we will need fencing of length equal to the perimeter of the square, which is 4x

The total amount of fencing is at most 52 feet

So , the inequality is

4x ≤ 52

Dividing both sides by 4, we get:

x ≤ 13

Therefore, the possible length of each side of the garden is less than or equal to 13 feet

And , each side of garden should be more than 0 , so

x > 0

Hence , the full inequality representing the possible length of each side of the garden would be 0 < x ≤ 13
