The volume of figure down below is 470.996 cubic in.

The volume of the cone is the product of one-third of the height, pie, and square of the radius that is;

The volume of the cone = 1/3(πr²)(height)

Since we can see that there are two cones combined together to form one figure.

So, Volume of first cone = 1/3(πr²)(height)

= 1/3(π 5²)(7)

= 1/3(π 25)(7)

= 183.166

Volume of second cone = 1/3(πr²)(height)

= 1/3(π 5²)(11)

= 1/3(π 25)(11)

= 287.83

Therefore, the volume of the figure is;

287.83 + 183.166

470.996

Answer:

\(y=\frac{1}{2} x+8\)

Step-by-step explanation:

Hi there!

Slope-intercept form: \(y=mx+b\) where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)

1) Determine the slope (m)

Perpendicular lines will always have slopes that are negative reciprocals of each other. For example, two perpendicular lines might have slopes of 3 and -1/3.

After observing the equation y=-2x-5, we can conclude that the slope is -2. Therefore, a line perpendicular to this line would have a slope of 1/2. Plug this into \(y=mx+b\):

\(y=\frac{1}{2} x+b\)

2) Determine the y-intercept (b)

\(y=\frac{1}{2} x+b\)

Plug in the given point (-4,6)

\(6=\frac{1}{2}(-4)+b\\6=-2+b\)

Add 2 to both sides

\(6+2=-2+b+2\\8=b\)

Therefore, the y-intercept is 8. Plug this back into \(y=\frac{1}{2} x+b\):

\(y=\frac{1}{2} x+8\)

The Simplification of the rational expression n[1/x - 1/(x + 2) / 2] gives 1/[x(x+2)] or 1/(x²+2x)

Simplification of a rational expression as a way of writing an expression in the most efficient and compact form without affecting the value of the original expression

[1/x - 1/(x+2)] /2

The LCM of x and (x+2) is x(x+2). Thus, we have:

[1/x - 1/(x+2)] /2 = [(x+2 - x) / x(x+2)] /2

                        = [ 2 / x(x+2)] /2

                        = 1 / [x(x+2)]

                        = 1/(x²+2x)

Thus, the expression simplifies to 1/[x(x+2)] or 1/(x²+2x)

Answer:

y = 8/5

Step-by-step explanation:

Formula we use,

→ y = kx

Then the value of y will be,

→ y = kx

→ y = (-2/5) × (-4)

→ y = (-2 × -4)/5

→ [ y = 8/5 ]

Hence, the value of y is 8/5.

To solve this problem, we can use the equation:

altitude = starting altitude - (rate of descent/ascent x time)

We can set the altitude of the descending airplane equal to the altitude of the ascending airplane and solve for the time.

54,000 - 3,300t = 2,700t

54,000 = 6,000t

t = 9

So the two airplanes will be at the same altitude after 9 minutes of descent and ascent. To find the altitude, we can plug t = 9 into either of the equations:

Altitude = 54,000 - 3,300(9) = 24,300 feet

OR

Altitude = 2,700(9) = 24,300 feet

Therefore, the two airplanes will be at the same altitude after 9 minutes of descent and ascent, at an altitude of 24,300 feet.

We can also use the difference in the rates of descent and ascent to find the time it will take for the two airplanes to be at the same altitude.

The difference in the rates is 3,300 - 2,700 = 600 feet per minute. We need to cover a vertical distance of 54,000 feet, so it will take:

54,000 / 600 = 90 minutes

So after 90 minutes, the two aeroplanes will be at the same altitude. To find the altitude, we can plug t = 90 into either of the equations:

Altitude = 54,000 - 3,300(90) = -207,000 feet

OR

Altitude = 2,700(90) = 243,000 feet

However, we see that the altitude calculated using the first method makes more sense in this situation, as it is a positive value and more realistic.

In conclusion, method 1 is easier to use and more appropriate for this situation, as it gives a more realistic and positive value for the altitude. Method 2 is more difficult to use and can lead to unrealistic or negative values in certain situations.

The volume of the given composite shape formed with a combination of cone & rectangular prism in cubic feet is 880 cubic feet and approximately cubic inches is 1,520,640 in3.

Various solid figures or shapes have various volumes. We have investigated a variety of three-dimensionally specified solids and shapes, such as cubes, cuboids, cylinders, cones, etc. A shape created from two or more basic shapes is referred to as a composite, compound, or complicated shape. Any three-dimensional shape, figure, or solid's volume is simply the quantity of space it occupies or contains. By finding the product of the dimensions we can calculate the volume of a solid or 3D figure. The measurement units are cubic units. These solids can be of various shapes like cube, cuboid also called rectangular prism, cone, cylinder, sphere , hemishphere, frustum, etc.

Volume of cone = \(\frac{\pi\ r^2h}{3}\)

Volume of cuboid=L.W.H

Given that the solid shape is made up of cone & cuboid(also called rectangular prism)

Volume of solid= volume of cone+volume of rectangular prism

Given dimensions:

Cone:radius(r) = 8 ft

         height(h) = 12 ft

Cuboid: Length(L) = 8 ft

            Width(W) = 7 ft

            Height(H) = 2 ft

Given that π = 3

Volume of solid =  \(\frac{\pi\ r^2h}{3}\) + L.W.H

                          =  \(\frac{3(8^2)(12)}{3} +8(7)(2)\)

                         = 64(12) + 56(2)

                         = 768 + 112

                         = 880

Volume of solid=880 cubic feet.

We know that 1 foot = 12 inches, & 1 cu. ft = 12x12x12 cu. inches

on converting volume into inches we get:

Volume of solid = 880 x 12 x 12 x 12 cubic inches

                          = 1,520,640 cu. inches.

Volume of solid is 1,520,640 in3

The type of hypothesis test to be used in this scenario is a one-sample t-test with a two-tailed alternative hypothesis.

The problem is asking to conduct a hypothesis test to determine whether the bag filling machine works correctly at the 433 gram setting.

The hypothesis test would involve a null hypothesis (H0) and an alternative hypothesis (Ha).

The null hypothesis is typically the hypothesis of "no effect" or "no difference" and is denoted as H0. In this case, the null hypothesis would be that the mean weight of potato chips in the bags filled by the machine at the 433 gram setting is equal to 433 grams. Therefore, the null hypothesis would be:

H0: μ = 433

The alternative hypothesis (Ha) is the hypothesis that we want to test, and it is denoted as Ha. In this case, the alternative hypothesis would be that the mean weight of potato chips in the bags filled by the machine at the 433 gram setting is not equal to 433 grams. Therefore, the alternative hypothesis would be:

Ha: μ ≠ 433

To conduct the hypothesis test, we would need to calculate the test statistic and compare it to the critical value. Since the sample size is large (n=301) and the population variance is unknown, we would use a t-test with a level of significance of 0.02.

If the calculated t-value falls outside the critical t-value, we would reject the null hypothesis and conclude that the bag filling machine does not work correctly at the 433 gram setting.

If the calculated t-value falls within the critical t-value, we would fail to reject the null hypothesis and conclude that there is not enough evidence to suggest that the bag filling machine does not work correctly at the 433 gram setting.

There are total 95040 number of different groups of 5 items can be selected from 12 distinct item.

According to the given question.

Total number of items, n = 12

Total numbers of items to be selected, r = 5

Since, we have to determine the number of different groups of 5 items that can be selected from 12 distinct items. So, we will find the number of different groups by permulation formula i.e.

\(^{n} P_{r} = \frac{n!}{(n-r)!}\)

Where,

\(^{n} P_{r}\) is the total number of permutations.

n is the total number of objects.

r is teh total number of objects to be selected.

Therefore,

The number of different groups or permutaions of 5 items that can be selected from 12 distinct group

\(^{12} P_{5}\)

\(= \frac{12!}{(12-5)!}\)

\(= \frac{12!}{7!}\)

\(= \frac{12\times11\times10\times9\times8\times7!}{7!}\)

= 12 × 11 × 10 × 9 × 8

= 95040

Hence, there are total 95040 number of different groups of 5 items can be selected from 12 distinct item.

Answer:

Let's assume Lisa tutored x students for private tutoring and (12 - x) students for group tutoring.

Therefore, the amount earned for private tutoring would be 25x and the amount earned for group tutoring would be 18(12 - x).

We know that the total amount earned was $265, so we can set up an equation:

25x + 18(12 - x) = 265

Simplifying the equation:

25x + 216 - 18x = 265

7x = 49

x = 7

Therefore, Lisa tutored 7 students for private tutoring and 12 - 7 = 5 students for group tutoring.

Step-by-step explanation:

Answer:

7

Step-by-step explanation:

Let's call the number of private tutoring sessions Lisa held "P" and the number of group tutoring sessions "G". We want to find out how many of each type of session she held.

From the problem, we know that:

Lisa charges $25 per private tutoring session, so the total amount she earned from private tutoring is 25P.

Lisa charges $18 per group tutoring session, so the total amount she earned from group tutoring is 18G.

Lisa tutored a total of 12 students, so the total number of tutoring sessions is P + G = 12.

We can write two equations based on this information:

25P + 18G = 265 (the total amount Lisa earned)

P + G = 12 (the total number of tutoring sessions)

To solve for P and G, we can use substitution. Solve the second equation for P:

P = 12 - G

Now substitute this expression for P in the first equation:

25P + 18G = 265

25(12 - G) + 18G = 265

300 - 25G + 18G = 265

-7G = -35

G = 5

So Lisa held 5 group tutoring sessions. We can find the number of private tutoring sessions by using the second equation:

P + G = 12

P + 5 = 12

P = 7

Following the standard form ax^3 + bx^2 + cx + d, the following constants are:

ax^3 = x^3 = 1x^3

a = 1

bx^2 = 0x^2
