Answers

C. 6 + 7 = 13

This is because 33, 21, and 15 are composite numbers, and 13 is not.

Final answer:

The sum of two consecutive integers being composite is disproved by the example 7 + 8 = 15, which is prime.

Explanation:

Counterexample: The sum of any two consecutive integers being a composite number is disproved by the example: 7 + 8 = 15, which is a prime number and not composite.

Explanation: A composite number is a positive integer that has more than two distinct positive divisors. In the case of 7 + 8 = 15, 15 only has divisors 1 and 15, making it a prime number, not composite.

Is 2 , -5 a solution to this system equation 2x + 5y = -19, 6y - 8x = -54 .? Justify your answer

Answers

The easiest way to solve this problem is to put (2, -5) into both equations and see if it satisfies/works for both of them. 2 = x and -5 = y.

So for 2x + 5y = -19, 
2(2) + 5(-5) = -19
4 - 25 = -19
-21 ≠ -19.

You can continue and try it out for 6y - 8x = -54 
6(-5) - 8(2) = -54
-30 - 16 = -54
-46 ≠ -54

But since (2, -5) already doesn't work for one equation, it cannot be a solution to the system of equations.

What will it cost to carpet a rectangular floor measuring 21 feet by 24 feet if the carpet costs $ 31.96 per square​ yard?

Answers

Area of a rectangle is equal to the base multiplied by the height. However, you are given the measurements in feet, and these must be divided by 3 to get yards.

21 becomes 7, and 24 becomes 8. 7/8 = 56 yards squared.

Multiplied by $31.96, the total comes out to $1789.76.

Use the appropriate property of determinants to find
a.a. do not evaluate the determinants.

Answers

Final answer:

The query is about applying properties of determinants to find a determinant without evaluating it. This involves using properties such as linearity, the effect of elemental operations, and the determinant of a product. The instructions also involve using simplified subscripts and omitting them if they are one.

Explanation:

Properties of determinants are often used to simplify the process of determinant calculation without actually evaluating the determinant. In this particular scenario, to find a given determinant using the appropriate property, one must consider the properties such as linearity with regards to rows or columns, the determinant of a product, and the effect of elemental operations such as switching or scaling rows or columns. Remember, if you apply a transformation that changes the determinant's value, you need to account for that change. For instance, if you multiply a row by a scalar, the determinant is also multiplied by that scalar. If you switch two rows, the sign of the determinant is flipped.

When simplifying subscripts in the final formula, you should follow the instructions explicitly: use the simplified subscript and omit the subscript if it is one, as these rules can affect the determinants in certain cases involving submatrices or cofactors. Keep these guidelines in mind when you are working with determinants, although it appears that this particular question might be incomplete and does not specify the determinant to be simplified.

A guy wire is stretched from the top of a tower to a point 10 yards from the base of the tower. The wire makes an angle of 65° with the ground. Draw a diagram and find the length of the guy wire. 4.2 yd. 11.0 yd. 23.7 yd.

Answers

The wire, the tower and the ground will make a right triangle with hypotenuse that is equal to the length of the wire, the height that is equal to the height of the tower and the base that measures from the base of the building to point the wire has touched the ground.
The length of the wire will be given by:
cos θ = (adjacent)/(hypotenuse)
thus
cos 65=10/h
h=10/cos 65
h=23.66 yds~23.7 yds
the answer is 23.7 yd

Answer:

23.7 yards

Step-by-step explanation:

Given :A guy wire is stretched from the top of a tower to a point 10 yards from the base of the tower. The wire makes an angle of 65° with the ground

To Find: Draw a diagram and find the length of the guy wire

Solution :

Refer the attached figure

We are given that A guy wire is stretched from the top of a tower to a point 10 yards from the base of the tower i.e. AC = 10 yards

We are also given that wire makes an angle of 65° with the ground i.e. ∠BAC = 65°

Now to find the length of the guy wire i.e. AB

We will use trigonometric ratio.

[tex]cos\theta = \frac{Base}{Hypotenuse}[/tex]

[tex]cos 65 ^{\circ} = \frac{AC}{AB}[/tex]

[tex]0.4226= \frac{10}{AB}[/tex]

[tex]AB= \frac{10}{0.4226}[/tex]

[tex]AB= 23.66[/tex]

Thus AB = 23.66 yards ≈ 23.7 yards

Hence the length of the guy wire is 23.7 yards

A farmer has harvested 60% of his crops. If he has harvested 72 acres, how many acres does the farmer have in all?

Answers

Answer:

120 Acres

Step-by-step explanation:

We want to find the total amount of acres that a farmer has given that we know how many acres are in a percentage of his farm.

The farmer has 120 acres in total.

We know that the 60% of the farmer crops is equivalent to 72 acres.

Now we want to find the 100%.

Then we write two equations:

100% = X

60% = 72 acres

Now we want to solve this for X.

To do it, we first take the quotient between the two equations:

100%/60% = X/(72 acres)

Now we solve this for X:

(100%/60%)*(72 acres) = X = 120 acres.

The farmer has 120 acres in total.

What is the total surface area of the figure shown

Answers

I think the answer is 3912.

Answer:  The total surface area is 2784 sq. inches.

Step-by-step explanation: We are given to find the total surface area of the given figure.

Let us divide the figure into two two cuboids 1 and 2 as shown in the attached figure.

We know that the surface area of a cuboid with length 'l', breadth 'b' and height 'h' is given by

[tex]S.A.=2(l_1b_1+l_1h_1+h_1b_1).[/tex]

The dimensions of the cuboid 1 are

[tex]length,~l_1=14~\textup{inches},\\\\breadth,~b_1=12~\textup{inches},\\\\height,~h_1=24-10=14~\textup{inches}.[/tex]

The dimensions of the cuboid 2 are

[tex]length,~l_2=30~\textup{inches},\\\\breadth,~b_1=14~\textup{inches},\\\\height,~h_1=10~\textup{inches}.[/tex]

Therefore, surface area of cuboid 1 is given by

[tex]S.A_1\\\\=2(l_1b_1+l_1h_1+h_1b_1)\\\\=2(14\times 12+14\times 14+14\times 12)\\\\=2(532)\\\\=1064~\textup{sq. inches.}[/tex]

And surface area of cuboid 2 is given by

[tex]S.A_2\\\\=2(l_2b_2+l_2h_2+h_2b_2)\\\\=2(30\times 14+30\times 10+14\times 10)\\\\=2(420+300+140)\\\\=2(860)\\\\=1720~\textup{sq. inches}.[/tex]

Thus, the total surface area of the figure is

[tex]S.A.=S.A_1+S.A_2=1064+1720=2784~\textup{sq. inches}.[/tex]

At noon, ship a is 30 nautical miles due west of ship
b. ship a is sailing west at 23 knots and ship b is sailing north at 17 knots. how fast (in knots) is the distance between the ships changing at 4 pm?

Answers

Let the origin of the coordinate system be the position of ship B at noon. Then the distance between the ships as a function of t (in hours) is
.. d = √((30 +23t)² +(17t)²)
.. = √(818t² +1380t +900)

The rate of change of distance with respect to time is
.. d' = (1/2)(2*818*t +1380)/√(818t² +1380t +900)
.. = (818t +690)/√(818t² +1380t +900)

At t=4, this is
.. d' = (818*4 +690)/√(818*16 +1380*4 +900)
.. = 3962/√19508
.. ≈ 28.37 . . . . . knots

The distance between the ships is increasing at about 28.37 knots at 4 pm.
Final answer:

The rate at which the distance between the two ships is changing is approximately 18.86 knots at 4pm.

Explanation:

To find the rate at which the distance between the two ships is changing, we can use the concept of relative velocity. Let's consider ship A as the reference point. The velocity of ship A relative to the Earth is given as 23 knots due west, and the velocity of ship B relative to the Earth is given as 17 knots due north. The velocity of ship B relative to ship A can be found by subtracting the velocities.

Using the Pythagorean theorem, we can find the magnitude of the velocity of ship B relative to ship A. This magnitude represents the rate at which the distance between the ships is changing. Therefore, at 4 pm, the distance between the ships is changing at a rate of approximately 18.86 knots.

b. 20.21 percent
c. 20.68 percent
d. 24.01 percent
e. 23.49 percent

Answers

Final answer:

The standard deviation of the returns is 21.5 percent.

Explanation:

To calculate the standard deviation of the returns, we need to follow these steps:

Calculate the mean of the returnsSubtract the mean from each return to find the deviationsSquare the deviationsCalculate the mean of the squared deviationsTake the square root of the mean of the squared deviations

Let's perform these steps:

The mean of the returns is (11 - 18 - 21 + 20 + 34) / 5 = 5.2 percentThe deviations are (11 - 5.2) = 5.8, (-18 - 5.2) = -23.2, (-21 - 5.2) = -26.2, (20 - 5.2) = 14.8, (34 - 5.2) = 28.8 percentThe squared deviations are 33.64, 538.24, 685.44, 219.04, 829.44 percent squaredThe mean of the squared deviations is (33.64 + 538.24 + 685.44 + 219.04 + 829.44) / 5 = 461.96 percent squaredThe square root of the mean of the squared deviations is sqrt(461.96) = 21.5 percent

Therefore, the standard deviation of the returns is 21.5 percent.
