Answer:

The correct answer is A. 35 and 46. When y is inversely proportional to x, it means that the ratio of x to y remains constant. In this case, when x = 3, y = 60, which means that the ratio of x to y is 3/60. Since the ratio is constant, we can use that ratio to find the values of y when x = 5 and x = 4. When x = 5, y = (3/60) x 5 = 35 and when x = 4, y = (3/60) x 4 = 46.

Answer:

Option A 35 and 46

Step-by-step explanation:

Answer:a =  17

b =  24

c =  16

d =  5

Step-by-step explanation:

a+b+c+d=62

a = b-7

c = 2/3·b

d = 5

a+b+c+d = 62

a-b = -7

2b-3c = 0

d = 5

Row 2 - Row 1 → Row 2

a+b+c+d = 62

-2b-c-d = -69

2b-3c = 0

d = 5

Row 3 + Row 2 → Row 3

a+b+c+d = 62

-2b-c-d = -69

-4c-d = -69

d = 5

d = 5/1= 5

c = -69+d/-4= -69+5/-4= 16

b = -69+c+d/-2= -69+16+5/-2 = 24

a = 62-b-c-d = 62-24-16-5 = 17

a = 17

b = 24

c = 16

d = 5

We know that the area of the given hexagon whose perimeter is 90ft is 584.56715 ft².

A hexagon, also known as a hexagon, is a six-sided polygon that forms the shape of a cube in geometry.

Any simple hexagon has 720° of internal angles in total.

No matter what kind of hexagon it is, they all have six sides.

This implies that all types of hexagons—regular, irregular, concave, and convex—have six sides apiece.

So, we know that the perimeter of the hexagon is 90ft.

Formula: 6a

Then, calculate the side as follows:

P = 6a

90 = 6a

a = 90/6

a = 15

Then, the area of the hexagon:

= 3√3/2a²

= 3√3/2*15²

= 584.56715

Therefore, we know that the area of the given hexagon whose perimeter is 90ft is 584.56715 ft².

The two smaller positive integers are:

m = 675

n = 45

And the sum is 675

We know that we have two positive integers, m and n.

And we know that:

3*m³ = 5*n⁵

One way of finding the numbers is evaluating one of the two in positive integers, until we get that the other one is also an integer.

For example,we can solve this for m to get:

m³ = (5/3)*n⁵

m = ∛((5/3)*n⁵)

Now just evaluate in different integer values of n.

if n = 3 we will get:

m = ∛((5/3)*3⁵) =  ∛(405) = 7.39

So this is not a solution.

Now I will use n = 45 = 5*3*3 (so all the exponents inside the cubic root are multiples of 3)

m = ∛((5/3)*(5*3²)⁵)

m = ∛(5⁶*3⁹) = 5²*3³ = 25*27 = 675

Then the sum is:

Answer:

x=1

Step-by-step explanation:

To find the value of "x", we can start by setting up an equation based on the information given in the problem:

3 + x = 2x - 2

To solve for "x", we can simplify the equation by subtracting "x" from both sides and adding 2 to both sides:

3 + x - x = 2x - 2 - x + 2

3 = x + 2

Finally, we can solve for "x" by subtracting 2 from both sides:

x = 1

Therefore, the number we're looking for is 1.

The percentage of people have iq scores somewhere between 70 and 130 is 95.44%.

To solve this problem, we need to standardize the IQ scores and then use a standard normal distribution table or calculator to find the proportion of scores between 70 and 130.

First, we need to calculate the z-scores for IQ scores of 70 and 130, using the formula:

z = (x - μ) / σ

where x is the IQ score, μ is the mean (100), and σ is the standard deviation (15).

For an IQ score of 70:

z = (70 - 100) / 15 = -2

For an IQ score of 130:

z = (130 - 100) / 15 = 2

We can now look up the proportion of scores between -2 and 2 in a standard normal distribution table or calculator. This represents the proportion of scores within two standard deviations of the mean, which is approximately 95% according to the empirical rule of normal distribution.

However, we want to find the proportion of scores between 70 and 130, not between -2 and 2. To do this, we need to subtract the proportion of scores below 70 (which is the same as the proportion below -2) from the proportion of scores below 130 (which is the same as the proportion below 2). The result gives us the proportion of scores between 70 and 130.

Using a standard normal distribution table or calculator, we can find that the proportion of scores below -2 (or 70) is 0.0228, and the proportion of scores below 2 (or 130) is 0.9772. Therefore, the proportion of scores between 70 and 130 is:

0.9772 - 0.0228 = 0.9544

This means that approximately 95.44% of people have IQ scores between 70 and 130.

-4m < 28. Divide both sides of the inequality by -4. Since we are dividing by a negative number, we need to reverse the inequality sign. m > -7. The solution to the inequality -4m < 28 is "m > -7".

To solve the inequality -4m < 28, we need to isolate the variable "m" on one side of the inequality sign. We can do this by dividing both sides of the inequality by -4. However, since we are dividing by a negative number, we need to reverse the inequality sign. After simplifying, we get the solution m > -7, which means that any value of "m" that is greater than -7 would satisfy the inequality. In other words, all values of "m" that are greater than -7 would make the inequality -4m < 28 true.

The tangent is an immediate line that simply touches the curve at a given point. The regular is an immediate line this is perpendicular to the tangent. the slope of any line perpendicular to a line with slope m is the terrible reciprocal −1/m.

Given a curve y = ax + b/√x.

with the constant value of a and b.

First, we need to find the derivative of the curve y = ax + b/√x in order to find the gradient of the tangent to the curve at any given point. We can use the quotient rule to differentiate the equation:

dy/dx = a - (b/2)x^(-3/2)

Now we can find the gradient of the tangent to the curve at the point (4, 12) by substituting x = 4 into this equation:

dy/dx = a - (b/2)4^(-3/2) = a - b/16

The gradient of the normal to the curve at this point is the negative reciprocal of the gradient of the tangent, so:

-1/m = -(a - b/16)

We know that the equation of the normal is given by:

3y + 2x = 44

We can use this to substitute in y in terms of x:

y = (44 - 2x)/3

Now we can substitute this into the expression for -1/m:

-1/m = -(a - b/16) = -(dy/dx) = -(a - b/2x^(3/2)) = -(a - b/2(4)^(3/2))

-1/m = -(a - b/8)

Simplifying this equation, we get:

1/m = a - b/8

Substituting the value of m = -3 into this equation (because the gradient of the normal is -3), we get:

-1/3 = a - b/8

Multiplying through by 8, we get:

-8/3 = 8a - b

We also know that the curve passes through the point (4, 12), so we can substitute this into the equation for the curve:

12 = 4a + b/2

Multiplying through by 2, we get:

24 = 8a + b

Now we have two equations in two variables:

-8/3 = 8a - b

24 = 8a + b

Adding the two equations together, we get:

56/3 = 16a

Dividing through by 16, we get:

a = 7/6

Substituting this into one of the equations, we get:

24 = 8(7/6) + b

b = 0

Therefore, the value of a is 7/6 and the value of b is 0.

The surface area for the given radius and height are For r = 5 and h = 2: TSA = 2π(5)(5+2) = 2π(5)(7) = 70π sq.cm. For r = 9 and h = 11: TSA = 2π(9)(20) = 360π sq. cm.

The entire area a cylinder occupies in three dimensions is known as the cylinder's area. The combined areas of the two circular bases and the curving surface make up the cylinder's surface area. In right cylinders, the axis line creates a right angle to the base, and the two circular bases are perfectly over one another. It is referred to as an oblique cylinder if one of the circular bases is misaligned and the axis does not make a right angle with the base.

The curving surface that sits in the center of the two circular bases opens to reveal a rectangular shape. A lateral surface is another name for this curved surface.

The total surface area of the cylinder is given by the formula:

TSA = 2πr(r + h)

For r = 5 and h = 2:

TSA = 2π(5)(5+2) = 2π(5)(7) = 70π sq.cm

For r = 9 and h = 11:

TSA = 2π(9)(20) = 360π sq. cm

For r = 9 and h = 8:

The common ratio of the geometric sequence -10, 20, -40 is -2.A geometric sequence is a sequence of numbers where each term is found by multiplying the previous term by a fixed number called the common ratio.

To find the common ratio of the sequence -10, 20, -40, we can divide each term by the previous term.

The second term divided by the first term gives:

20 / (-10) = -2

The third term divided by the second term gives:

(-40) / 20 = -2

We can see that the quotient is the same in both cases, which means that the common ratio of the sequence is -2.

This tells us that to find the next term in the sequence, we multiply the previous term by -2. For example, to find the fourth term, we would multiply -40 by -2 to get 80, which would be the next term in the sequence.

In summary, the common ratio of the geometric sequence -10, 20, -40 is -2.
