a) The value of x is 42.6 when k =16/3 is directly proportional to y.

b) The value of x is -56 when k is -7  is directly proportional to y.

What kind of variation is one where x and y are directly proportional?

x varies directly as y

x α y

x = ky

a) x=6 ; y = 32

x = ky

6 = k(32)

k = 16/3

if y = 8

then,

x = (16/3) * 8

= 128/3

x = 42.6

Hence, the value of x is 42.6 when k =16/3 is directly proportional to y.

b) x= 14 and y = -2

x = ky

14 = k(-2)

k = -7

if y = 8

then,

x = ky

x= (-7) 8

x = -56

Hence, the value of x is -56 when k is -7  is directly proportional to y.

The shape that can tessellate without leaving gaps is the hexagon (option A).

The shapes that can tessellate without leaving gaps are shapes that can be repeated to completely cover a flat surface without any overlaps or gaps. Among the options provided, the shape that will tessellate without leaving gaps is the hexagon (option A).

A hexagon is a six-sided polygon with equal sides and angles. It is a regular polygon, which means all of its sides and angles are equal. A regular hexagon can be arranged and repeated in a pattern to fill a plane without any gaps or overlaps. Bees' honeycombs are a real-world example of hexagonal tessellation.

On the other hand, octagons (option B) and pentagons (option C) do not tessellate by themselves without gaps. While they can be used in combination with other shapes to create tessellations, they cannot tessellate on their own.

A circle (option D) cannot tessellate without leaving gaps. A circle is a curved shape, and it cannot form a repeating pattern that completely covers a flat surface without overlaps or gaps.

In summary, the shape that can tessellate without leaving gaps is the hexagon (option A).

The time spent higher than 26 meters above the ground is 0.42 minutes. Answer: 0.42

A Ferris wheel is 30 meters in diameter and boarded from a platform that is 4 meters above the ground.

The six o'clock position on the Ferris wheel is level with the loading platform.

The wheel completes 1 full revolution in 2 minutes.

We have to find how many minutes of the ride are spent higher than 26 meters above the ground.

So, let's start with some given data,Consider the height of a person at the six o'clock position = 4 meters

So, the height of a person at the highest point = 4 + 15 = 19 meters (since the diameter is 30 meters, the radius will be 15 meters)

Also, the height of a person at the lowest point = 4 - 15 = -11 meters

Therefore, the Ferris wheel completes one cycle from the lowest point to the highest point and back to the lowest point.

So, the total distance travelled will be = 19 + 11 = 30 meters.

Also, we are given that the wheel completes 1 full revolution in 2 minutes.

We need to calculate the time spent higher than 26 meters above the ground.

So, the angle between the 6 o'clock position and 2 o'clock position will be equal to the angle between the 6 o'clock position and the highest point.

This angle can be calculated as follows:

Angle = Distance travelled by the Ferris wheel / Circumference of the Ferris wheel * 360 degrees

Angle = 30 / (pi * 30) * 360 degrees

Angle = 360 degrees / pi

= 114.59 degrees

So, the total angle between the 6 o'clock position and the highest point is 114.59 degrees.

Now, we need to find out how much time is spent at an angle greater than 114.59 degrees.

This can be calculated as follows:

Time = (Angle greater than 114.59 degrees / Total angle of the Ferris wheel) * Total time taken

Time = (180 - 114.59) / 360 * 2 minutes

Time = 0.42 minutes

Answer:

y = (3/2)x + 2

Step-by-step explanation:

The equation of a straight line is given by:

y = mx + b;

where y, x are variables, m is the slope of the line and b is the y intercept (value of y when x is 0).

From the graph, we can see that the y intercept is 2 units. Also, the line passes through point (2, 5) and (-2, -1). Therefore the slope of the line is:

\(slope(m)=\frac{y_2-y_1}{x_2-x_1}=\frac{-1-5}{-2-2}=\frac{3}{2}\)

Using the equation a straight line:

y = mx + b; substituting gives:

y = (3/2)x + 2

The sine of ∠B is equal to 6/8, which reduces to 3/4 when both the numerator and denominator are divided by 2.

The sine of an angle is equal to the length of the opposite side divided by the length of the hypotenuse. The angle in question is ∠B which is in a special right triangle. This triangle is a 30-60-90 triangle which means two of its angles are 30 degrees and 60 degrees and the third angle is 90 degrees. Since ∠B is the angle opposite the side with length 6, the sine of ∠B is equal to 6/8. To reduce this fraction, divide both the numerator and denominator by 2. This leaves us with 3/4 which is the sine of ∠B.To recap, the sine of an angle is equal to the length of the opposite side divided by the length of the hypotenuse. As ∠B is in a 30-60-90 triangle, the sine of ∠B is equal to 6/8. To reduce this fraction, divide both the numerator and denominator by 2, leaving us with the final answer of 3/4.

Explanation:

Lateral Surface Area of the triangular prism = (perimeter × height) + 2(area of base)

Since it is anequilateral triangle, all 3 sides of the triangle are equal

Perimeter = 10cm + 10cm + 10cm = 30 cm

area of base = area of triangle

Area of equilateral triangle = side² × (√3)/4

side = 10cm

Area of equilateral triangle = 10² × (√3)/4 = 100/4 × √3 = 25√3

height = 14cm

Lateral Surface Area of the triangular prism = (30 cm × 14cm) +2(25√3)

Lateral Surface Area of the triangular prism = 420 + 50√3 = 420 + 86.6

Lateral Surface Area of the triangular prism = 506.6cm²

The area of triangle used = 1/2 bh = 1/2(10cm)(8.3cm) = 83cm²

The Lateral Surface Area of the triangular prism = 420 + 83 = 503 cm² (4th option)

Step-by-step explanation:

Let's call the average speed of the tortoise "t" (in meters per hour) and the average speed of the hare "h" (in meters per hour).

From the problem, we know that:

The tortoise leaves 8 minutes before the hare, so they have a 4-minute head start.

The hare crosses the finish line 4 minutes before the tortoise, so they have a 4-minute lead.

Therefore, the total time it takes for the hare to finish the race is 8 minutes less than the time it takes for the tortoise to finish the race. Let's call this time difference "dt".

The distance the hare runs is 21 meters, and the distance the tortoise runs is also 21 meters, so we have:

h * dt = 21 - t * (dt + 4 minutes)

To solve for the average speeds "t" and "h", we need to convert everything to units of hours. Let's convert 4 minutes to hours:

4 minutes = 4/60 hours = 1/15 hours

So, we can now rewrite the equation in terms of hours:

h * dt = 21 - t * (dt + 1/15 hours)

Rearranging and solving for t, we find:

t = (21 + h * dt) / (dt + 1/15)

Now, the hare runs 0.5 meters per hour faster than the tortoise, so:

h = t + 0.5

Substituting h = t + 0.5 into the equation for t, we get:

t = (21 + (t + 0.5) * dt) / (dt + 1/15)

Solving for t, we find:

t = 40/3 meters per hour

Finally, we can find the average speed of the hare by using h = t + 0.5:

h = 40/3 + 0.5 = 40/3 + 30/60 = 40/3 + 30/3 / 60 = 70/3 meters per hour

So the average speed of the tortoise is 40/3 meters per hour, and the average speed of the hare is 70/3 meters per hour

Answer:

2.3 hours

Step-by-step explanation:

From 3:12 pm to 4:12 pm, one hour passes.

From 4:12 pm to 5:12 pm, another hour passes.

From 5:12 pm to 5:30 pm, there are 18 minutes that pass.

Therefore, the total time elapsed is 2 hours and 18 minutes out of 60 minutes in an hour.

To convert this to a fraction, we can write:

2 hours + 18 minutes = 2 + 18/60 hours = 2.3 hours

So, 2.3/1 hour passes from 3:12 pm to 5:30 pm.

the weight that corresponds to each of the events are:

a) The weight is less than 380 grams: \($P(X < 380)=0.266$\).

b) The weight is between 375 and 395 grams: \($P(375 < X < 395)=0.7887$\).

c) The weight is greater than 400 grams: \($P(X > 400)=0.0304$\).

Let X be the weight of a small Starbucks coffee. We are given that X is normally distributed with mean \($\mu=385$\) grams and standard deviation \($\sigma=8$\).

We want to find the weight that corresponds to each of the following events:

a) The weight is less than 380 grams.

b) The weight is between 375 and 395 grams.

c) The weight is greater than 400 grams.

To solve these problems, we first standardize the distribution by finding the corresponding z-scores using the formula:

\($z=\frac{X-\mu}{\sigma}$$\)

a) The weight is less than 380 grams.

We want to find P(X<380). We can find the z-score for X=380 as follows:

\($z=\frac{380-385}{8}=-0.625$$\)

Using a standard normal table or calculator, we find that the probability P(Z<-0.625)=0.266. Therefore,

\($P(X < 380)=P\left(Z < -\frac{0.625}{1}\right)=0.266$$\)

b) The weight is between 375 and 395 grams.

We want to find \($P(375 < X < 395)$\). We can find the z-scores for X=375 and X=395 as follows:

\($z_1=\frac{375-385}{8}=-1.25,\quad z_2=\frac{395-385}{8}=1.25$$\)

Using a standard normal table or calculator, we find that the probability P(-1.25<Z<1.25)=0.7887. Therefore,

\($P(375 < X < 395)=P\left(-1.25 < Z < 1.25\right)=0.7887$$\)

c) The weight is greater than 400 grams.

We want to find P(X>400). We can find the z-score for X=400 as follows:

\($z=\frac{400-385}{8}=1.875$$\)

Using a standard normal table or calculator, we find that the probability P(Z>1.875)=0.0304. Therefore,

\($P(X > 400)=P\left(Z > \frac{1.875}{1}\right)=0.0304$$\)

Therefore, the weight that corresponds to each of the events are:

a) The weight is less than 380 grams: \($P(X < 380)=0.266$\).

b) The weight is between 375 and 395 grams: \($P(375 < X < 395)=0.7887$\).

c) The weight is greater than 400 grams: \($P(X > 400)=0.0304$\).
