Answer:  The required solution for p is [tex]p=2mr+q.[/tex]

Step-by-step explanation:  We are given to solve the following equation for the variable p :

[tex]2m=\dfrac{p-q}{r}~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

To solve the given equation for p, we must take p on one side of the equation and all other terms on the other side.

From equation (i), we get

[tex]2m=\dfrac{p-q}{r}\\\\\Rightarrow 2mr=p-q~~~~~~~~~~~~~~[\textup{Cross-multiplication}]\\\\\Rightarrow p=2mr+q.[/tex]

Thus, the required solution for p is [tex]p=2mr+q.[/tex]

The lesser number is 13 and the bigger number is 17.

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

The sum of two numbers is 30 the difference between the two numbers is 4. Let the number be x and y where x > y. Then the equations will be

x + y = 30       ...1

x - y = 4         ...2

Add both equations, then we have

2x = 34

x = 17

Then the other number will be

17 + y = 30

y = 30 - 17

y = 13

The lesser number is 13 and the bigger number is 17.

Answer:

1 nanosecond = 1 billionth of a second

Step-by-step explanation:

A nanosecond (ns) is an SI unit of time equal to one billionth of a second, that is, ​1⁄1 000 000 000 of a second, or 10^−9 seconds. The term combines the prefix nano- with the basic unit for one-sixtieth of a minute. A nanosecond is equal to 1000 picoseconds or ​1⁄1000 microsecond.

The actual distance between two cities that are 4.2 cm apart on a map with a scale of 1 cm : 50 mi is 210 miles. The distance was calculated using a direct proportion based on the map's scale.

To determine the actual distance between two cities that are 4.2 cm apart on a map with a scale of 1 cm : 50 mi, you can use the following method:

First, understand that the scale means for every 1 cm on the map, the actual distance is 50 miles. Therefore, you can set up a direct proportion to solve for the actual distance.

Scale of map: 1 cm : 50 mi
Distance on map: 4.2 cm

Setting up the proportion, we get:

Now, solve for 'x' which represents the actual distance between the two cities.

The actual distance between the two cities is 210 miles.

Your answer would be 5/6

Answer: There are 6 nickels, 7 dimes and 8 quarters in the bag.

Step-by-step explanation:  Given that the bag contains coins of nickels, dimes and quarters. There are total 21 coins in the bag and number of dimes is one more than the number of nickels.

Let 'x' be the number of nickels in the bag.

So, number of dimes will be (x+1) and number of quarters will be (21-x-x-1) i.e., (20-2x).

Since there are total $3.00 amount of money in the bag, so

[tex]0.05x+0.10(x+1)+0.25(20-2x)=3\\\\\Rightarrow\dfrac{x}{20}+\dfrac{x+1}{10}+\dfrac{20-2x}{4}=3\\\\\Rightarrow \dfrac{x+2x+2+100-10x}{20}=3\\\\\Rightarrow -7x+102=60\\\\\Rightarrow 7x=42\\\\\Rightarrow x=6.[/tex]

Therefore, number of nickels = 6, number of dimes = 6+1 = 7  and number of quarters = 20-2×6 = 8.

Thus, there are 6 nickels, 7 dimes and 8 quarters in the bag.

The lines l1 and l2 are perpendicular to each other. They form a 270° angle which means they form three right angles. Hence they are indeed perpendicular due to the fact they intersect at a point if one line is extended by 180°.

In this case, we are asked to determine if the lines l1 and l2 are parallel, perpendicular or neither. One critical information presented is that the two lines are perpendicular and form a 270° angle between each other.

Typically, when two lines are perpendicular, they form a right angle, which is 90°. However, a 270° angle suggests they make three right angles, meaning they do not directly intersect at a right angle, but do meet at a point if you extend one line 180° further. Hence, they are indeed perpendicular.

So, although it might seem a bit unusual, based on this information, the lines l1 and l2 are perpendicular to each other.

To find the value of y for the point (-1, y) in the equation y = 3x + 4, plug in -1 for x and solve: y = -3 + 4, which simplifies to y = 1. Thus, the value of y is 1.

The student needs to determine the value of y when x is -1 for the equation y = 3x + 4. To find y, we substitute -1 in place of x and solve the equation:

y = 3(-1) + 4

y = -3 + 4

y = 1

Therefore, the value of y for the point (-1, y) is 1.

Answer:

f(2) = 9.

Step-by-step explanation:

Given : f(x) = 2x² – 3x + 7.

To find : What is the value of the function when x = 2.

Solution : We have given that f(x) = 2x² – 3x + 7.

For, x = 2

f(2)  = 2(2)² – 3(2) + 7.

f(2) = 2 *4 -6 +7

f(2) = 8 - 6 +7.

f(2) = 2 +7

f(2) = 9.

Therefore, f(2) = 9.

Answer:

Speed of sound, v = 340 m/s

Step-by-step explanation:

It is given that,

A exploded 1360 meters away, d = 1360 meters

time taken, t = 4 seconds

We need to find the speed of the travelled sound. Speed of sound is equal to the distance covered divided by total time taken i.e.

[tex]v=\dfrac{d}{t}[/tex]

[tex]v=\dfrac{1360\ m}{4\ s}[/tex]

v = 340 m/s

So, the speed with which sound is travelled is 340 m/s. Hence, this is the required solution.

To find the points where the tangent is horizontal on the given curve, find the values of x for which the derivative is zero.

To find the points on the given curve where the tangent is horizontal, we need to find the values of x for which the derivative of the curve is equal to zero. This is because the derivative represents the slope of the tangent line. Setting the derivative equal to zero and solving for x will give us the x-coordinates of the points.

The given curve is y = 7x³ + 6x² - 8x + 7. To find the derivative of this curve, we use the power rule of differentiation. The derivative is dy/dx = 21x^2 + 12x - 8.

Setting dy/dx equal to zero, we have 21x² + 12x - 8 = 0. To solve this quadratic equation, we can use the quadratic formula: x = (-b ± √(b² - 4ac)) / (2a). Using this formula, we can find the values of x that make the derivative equal to zero.

Answer:

20 centimeters apart.

Step-by-step explanation:

Tanya planted seedlings in her garden over the weekend.

The instructions that came with the seedlings stated that they need to be planted 0.2 meters apart.

Tanya has a measuring tape that has values in centimeters.

As we know 1 meter = 100 centimeters

therefore, 0.2 meter = 0.2 × 100 = 20 centimeters

So Tanya need to be planted 20 centimeters apart.

Answer:

8-5n= -138

You add 8 to each side

5n= -130

Divide by 5 on each side

n = -26

Step-by-step explanation:

Sketch  a right triangle having adjacent side(A) is given as “3”, hypotenuse side (H) is “x” and assigning angle “a” as the angle between A and H. Using Pythagorean theorem, you will get “square root of x-squared minus 9” as the opposite side (O). Using SOH CAH TOA function, and since secant is the reciprocal of cosine, sec(a) = x/3. Thus, a = arcsec(x/3). The remaining expression tan(a) is Opposite side over Adjacent side which is equal to “square root of x^2 - 9” over "3". Therefore, the algebraic expression would be: tan(arcsec(x/3)) = “sqrt (x^2 -9)” /3. Different answers can be made depending on which side you consider the “3” and “x”.
