Answer 1

{y | y < 3/4}!!!!!!!!!!!!!!!

Answer 2

Answer:

A- {y | y > -4}

Step-by-step explanation:

Since the range is x - 4 the range will only go down to - 4. It will not go past the - 4 mark. Therefore the range should be anything greater then -4 to infinity.

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.

ABC is isosceles with AB=AC=8 units and BC=6 units. D and E are midpoints of AB and BC respectively. Calculate the length of DE?

Answers

The triangle is drawn and is shown in the image attached with.

We get two similar triangles. Triangle ABC and Triangle ADE. Since the triangles are similar the ratio of their corresponding sides will be the same.

D and E are the midpoints of AB and BC, therefore, AD and AE are both 4 units in length. Using the property of similar triangles, we can say:

AD : DE= AB : BC
AD = 4 units
AB = 8 units
BC = 6 units
DE = unknown = x units

So,

[tex]4 :x = 8 : 6 \\ \\ \frac{4}{x} = \frac{8}{6} \\ \\ x=4* \frac{6}{8}=3 [/tex]

Therefore, the length of DE will be 3 units

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.

Convert the following decimal to a common fraction. Reduce to lowest terms 0.2 =

Answers

The answer is 1/5 hope this helps

The decimal conversion of 0.2 would be 2/10 since the decimal is rounded to the tenths place.

When finding the lowest terms of a fraction, you want to find the highest number that can go into both numbers, or greatest common factor (GCF), of both the numerator and the denominator. In this case, the greatest common factor would be 2, since it can go into both 2 and 10 without any remainders.

2 can go into 2 once, and into 10 five times, making the reduced term 1/5.

Find an equation for the contour of f(x,y)=2x2y+7x+20f(x,y)=2x2y+7x+20 that goes through the point (3,−2)(3,−2).

Answers

That equation will be
.. f(x, y) = f(3, -2)
.. 2x^2y +7x +20 = 2*3^2*(-2) +7*3 +20

2x^2*y +7x +20 = 5

A contour at height c have [tex]\mathbf{f(x, y) = c}[/tex] as its equation

A stock had returns of 11 percent, -18 percent, -21 percent, 20 percent, and 34 percent over the past five years. what is the standard deviation of these returns?
a. 18.74 percent
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.

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.

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.

How many square feet of tile will be needed to cover the kitchen floor not counting the area used by the stove and the refrigerator?

Answers

Stove area = 12 square feet
Refrigerator area = 20 square feet
Entire kitchen floor = 270 square feet
12 + 20 = 32 square feet
270 square feet - 32 square feet = 238 square feet
238 square feet will be needed

Number of square feet of tile will be needed to cover the kitchen floor is 238 square feet.

Given that, a rectangular kitchen floor measures 18 feet by 15 feet.

What is the area of a rectangle?

The area occupied by a rectangle within its boundary is called the area of the rectangle. The formula to find the area of a rectangle is Area = Length × Breadth.

Area of a rectangular kitchen floor

= 18×15

= 270 square feet

Area covered by a stove

= 3×4

= 12 square feet

Area covered by a refrigerator

= 4×5

= 20 square feet

Area covered by tiles

= 270-(12+20)

= 270-32

= 238 square feet

Therefore, number of square feet of tile will be needed to cover the kitchen floor is 238 square feet.
