The amount of water needed for 90 mL concentrate is 225 mL

From the question, we have the following parameters that can be used in our computation:

2 parts concentrate to 5 parts of water

The above parameter can be expressed using the following ratio expression

Ratio = Concentrate : Water

Substitute the known values in the above equation, so, we have the following representation

Concentrate : Water = 2 : 5

From the question, we have

Concentrate = 90 ml

Substitute the known values in the above equation, so, we have the following representation

90 : Water = 2 : 5

Multiply the second ratio by 45

This gives

90 : Water = 90 : 225

By comparison, we have

Water = 225

Hence, the amount of water  is 225 mL

The surface area of the composite figure is 217.28yd²

The volume of the composite figure is 141.12yd³

A composite figure can be defines as a shape created with two or more basic shapes.

The composite figure consist of a triangular prism and cuboid

The surface area of the cuboid =2(lh+lb+bh)

= 2 ( 4.8×2.8 + 8× 2.8 + 4.8×8)

= 2( 13.44+22.40+38.4)

= 2(74.24)

= 148.48yd²

The surface area of the prism = 2B+ph

Base area = 1/2 × 3×8 = 12

The perimeter = 3+8+5 = 16

SA = 2×12+ 16×2.8

SA = 24+44.8

SA = 68.8yd²

the surface area of the composite figure = 148.48+68.8 = 217.28yd²

The volume of the cuboid = 4.8× 2.8 × 8 = 107.52yd³

Volume of the prism = base area × height = 12×2.8 = 33.6yd³

Therefore the volume of composite figure= 107.52+33.6 = 141.12 yd³

An inequality can be described as a relation with a non-equal comparison between two elements, values, variables, numbers or other algebraic expressions.

Inequalities are mostly used to compare two numbers on the number line on the basis of their size.

It is important to note that the positive values are greater than the negatives .

Also, zero(0) is greater than the negative numbers from the left side of the number line.

The 50th derivative of y=cos2x is [tex]& y^{50}(x)=-2^{50} \cos (2 x)[/tex].

Consider y=cos 2x

Derivative: The rate of change of a function with respect to a variable. Derivatives are fundamental to the solution of problems in calculus and differential equations.

Finding the nth derivative means to take a few derivatives (1st, 2nd, 3rd…) and look for a pattern. If one exists, then you have a formula for the nth derivative. To find the nth derivative, find the first few derivatives to identify the pattern.  Apply the usual rules of differentiation to a function, then find each successive derivative to arrive at the nth.

The first derivative is

[tex]$$\begin{aligned}& y^{\prime}=-2 \sin 2 x \\& =-2\left[\cos \left(2 x+\frac{\pi}{2}\right)\right]\end{aligned}$$[/tex]

The second derivative is

[tex]$$y^{\prime \prime}=-2^2\left[\cos \left(2 x+2 \cdot \frac{\pi}{2}\right)\right]$$[/tex]

Similarly, we get the [tex]n^{th}[/tex] derivative

[tex]$$y^n(x)=-\left[2^n \cos \left(2 x+n \frac{\pi}{2}\right)\right]$$[/tex]

When n=50

[tex]$$\begin{aligned}& y^{50}(x)=-\left[2^{50} \cos \left(2 x+50 \cdot \frac{\pi}{2}\right)\right] \\& y^{50}(x)=-2^{50} \cos (2 x)\end{aligned}$$[/tex]

The least possible value of p+n+d+q would be 6 + 3 + 3 + 3 = 15. So, the least possible value of p+n+d+q is 15.

To solve this problem, we need to use the concept of prime factorization. First, we need to find the least common multiple of the four numbers, p, n, d, and q. To do this, we can factor each of the numbers into their prime factors:

[tex]p = 2^a * 3^b * 5^c * 7^d \\n = 2^e * 3^f * 5^g * 7^h\\d = 2^i * 3^j * 5^k * 7^l\\q = 2^m * 3^n * 5^o * 7^p[/tex]

The least common multiple (LCM) of p, n, d, and q is the product of the highest power of each prime factor that appears in any of the numbers. For example, the LCM would be 2^i * 3^j * 5^k * 7^l, because that is the highest power of each prime factor that appears in any of the numbers.

Now that we have the LCM of the four numbers, we need to find out how much money that is worth. Since we know that the total value is $1.08, we can divide both sides by the LCM to find out how much each factor is worth:

[tex]1.08/2^i * 3^j * 5^k * 7^l = x[/tex]

x = 0.01102

So, each factor of the LCM is worth 0.01102. Now, we just need to add up the total number of factors that appear in p, n, d, and q. The least possible value of p+n+d+q would be the sum of the number of powers of each prime factor in p, n, d, and q. For example, if[tex]p = 2^2 * 3^3 * 5^1 * 7^0, n = 2^1 * 3^2 * 5^0 * 7^2, d = 2^0 * 3^1 * 5^2 * 7^1,[/tex] and [tex]q = 2^2 * 3^0 * 5^2 * 7^1.[/tex]

Answer: To write the equation of the line that is parallel to the graph of y = x – 4 and passes through the point (-2, 3), we can use the fact that parallel lines have the same slope.

The slope of y = x – 4 is 1, since the coefficient of x is 1.

So, we can write the equation of the line in the slope-intercept form y = mx + b, where m = 1 and b is the y-intercept. To find the y-intercept, we can substitute the point (-2, 3) into the equation:

y = 1x + b

3 = 1(-2) + b

3 = -2 + b

b = 5

so the equation of the line in slope-intercept form is y = 1x + 5

To write the equation of the line that is parallel to the graph of y + 2x = 4 and passes through the point (-1, 2), we can use the fact that parallel lines have the same slope.

The slope of the equation y + 2x = 4 is -1/2, since the coefficient of x is -1/2.

So, we can write the equation of the line in the slope-intercept form y = mx + b, where m = -1/2 and b is the y-intercept. To find the y-intercept, we can substitute the point (-1, 2) into the equation:

y = -1/2 x + b

2 = -1/2(-1) + b

2 = -1/2 + b

b = 5/2

so the equation of the line in slope-intercept form is y = -1/2x + 5/2

It's important to note that the slope-intercept form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept. The y-intercept is the point where the line crosses the y-axis.

These conversions can be carried out for any amount of mass given in grams.

0.379 g = 379 mg

787 g = 0.787 Mg

74.3 g = 0.0743 kg

1. To convert 0.379 g to mg, multiply 0.379 by 1000. 0.379 x 1000 = 379 mg.

2. To convert 787 g to Mg, divide 787 by 1000. 787 / 1000 = 0.787 Mg.

3. To convert 74.3 g to kg, divide 74.3 by 1000. 74.3 / 1000 = 0.0743 kg.

The 0.379 g was converted to 379 mg, 787 g was converted to 0.787 Mg, and 74.3 g was converted to 0.0743 kg.

The conversion of 0.379 g to mg is done by multiplying 0.379 by 1000. The result is 379 mg. To convert 787 g to Mg, divide 787 by 1000. The result is 0.787 Mg. To convert 74.3 g to kg, divide 74.3 by 1000. The answer is 0.0743 kg. In summary, 0.379 g was converted to 379 mg, 787 g was converted to 0.787 Mg, and 74.3 g was converted to 0.0743 kg. This demonstrates how to convert mass from grams to different derived units. These conversions can be carried out for any amount of mass given in grams.

In mathematics, an inequality establishes the relationship between two values that are not equal. Egality is not the same as inequality. Use the not equal symbol () in most cases when two values are not equal. To contrast values, whether they are tiny or huge, different inequalities are employed.

Ryosuke drove his friend 24 miles, which used 1.14 gallons of gas. The total cost of the gas was $4.64, calculated by multiplying 1.14 gallons by the price of one gallon which was $4.05.

1. Calculate the number of miles driven: Subtract the odometer reading when Ryosuke picked his friend up (74,568) from the odometer reading when he dropped his friend off (74,592). This gives us the total number of miles driven (24).

2. Calculate the number of gallons used: Divide the total number of miles driven (24) by the car's gas mileage (28). This gives us the number of gallons used (1.14).

3. Calculate the cost of the gas: Multiply the number of gallons used (1.14) by the price of one gallon of gas ($4.05). This gives us the cost of the gas used ($4.64).

y ≥ - x - 2

The system of the given inequalities represents a region in the x-y plane that is the solution set for the inequalities. To find the solution set, we can graph the inequalities on the same coordinate plane and find the region where they overlap.

The inequality y ≥ x + 1 represents the line y = x + 1 and all the points above it. Similarly, y ≤ -x - 2 represents the line y = -x - 2 and all the points below it.

When we graph these two lines on the same coordinate plane, we find that the lines intersect at the point (-1.5,-0.5) which means that the common region of the two lines(the region where they overlap) is the empty set. This means that there is no point that satisfies both inequalities and therefore there is no solution for the given system of inequalities.
