Step-by-step explanation:

one leg of a right triangle is 6 inches longer than the other leg, and the hypotenuse is 30 inches. Thus,

The lengths of the legs of the triangle are 18 inches,24 inches and  30 inches.

Three vertices make up a triangle, a three-sided polygon. The angles of the triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees in total.

Given that,

one leg of a right triangle is 6 inches longer than the other leg.

hypotenuse is 30 inches.

Let assume, the other leg be x

It is given that, one leg of a right triangle is 6 inches longer than the other leg. So, One leg = x + 6

Since it is a right angled triangle,

h² = p² + b²

Where, h = hypotenuse

p = perpendicular

B = Base

So, (30)² = (x+6)² + x²

or, x = -24, 18

As, the length of side cannot be negative so x becomes 18.

Thus, x + 6 = 18 + 6 = 24 inches

Hypotenuse = 30 inches

Hence, the lengths of the legs of the triangle are 18 inches, 24 inches and  30 inches.

Option (a) is correct option.

The ratio connecting two given numbers in what is known as a proportional relationship is the constant of proportionality.

Constant ratio, constant rate, unit rate, constant of variation, and even rate of change are other names for the constant of proportionality. When two or more parameters are proportional to one another either directly or indirectly, their relationship is stated as a = kb or a = k/b, where k denotes the direction of the relationship between the two variables.The proportionality constant is thus k.

Constant of proportionality in given case is nothing but slope of given graph.

Slope is given by tangent of the angle made by line with positive x-axis.

p =slope of line

p = [tex]\frac{y-axis}{x-axis}[/tex]

p=[tex]\frac{140}{2}[/tex] = 70

So, 55 × 7 = 385

She would get after 7 years all total  = (1100 + 385) = $1485

The correct option is c. It is a solution to f(x) = g(x) because it is the x-coordinate where the two graphs intersect.

x = −1 is also a solution to f(x) = g(x) because it is asking for the values of x that make f(x) equal to g(x). In this case, x = −1 is a value that makes both f(x) and g(x) equal to −1, so it is a solution to the equation f(x) = g(x).

The graph of f(x) = g(x) is simply the set of all points that are on both the graph of f(x) and the graph of g(x)

These points are the points where the two graphs intersect. In this case, the graph of f(x) = g(x) is a single point at x = −1, which is the x-coordinate where the two graphs intersect

The answer to this Question based on speed is 1m/s

What is speed?

Speed can be defined as the rate at which an object moves from one point to another. It is usually measured in units of distance per unit of time, such as kilometers per hour (km/h) or miles per hour (mph). Speed is a scalar quantity, meaning it has magnitude but no direction. Speed can also be thought of as the rate of change of position. When an object is in motion, its speed is constantly changing due to the force of gravity, air resistance, and other external factors. The speed of an object can be affected by its weight, shape, and size. An object's speed can also be affected by other factors such as the friction of the surface it is moving on and the wind or air resistance. Speed is an important concept in physics, engineering, and many other fields.

we are given that velocity as a function of time along a single direction

we write v(t) = -2t+5

hence speed = mod(velocity)

speed at t = 2 sec = mod (velocity at t = 2 sec)

speed = mod(-2(2)+5)

speed = mod(-4+5)

speed = 1 m/s

If the ratio of the measure of the three sides of the triangle is 9:7:5 and the perimeter is 191.1 inches, then the three sides of the triangle are 81.9 inches, 63.7 inches and 45.5 inches

The ratio of the measure of the three sides of a triangle = 9 : 7 : 5

Then three sides of the triangles = 9x, 7x and 5x

Where x is the constant

The  perimeter of the triangle = 191.1

The perimeter of the triangle is the sum of the three sides of the triangle

Then the equation will be

9x + 7x + 5x = 191.1

21x = 191.1

x = 191.1 / 21

x = 9.1

The first side = 9x

= 9 × 9.1

= 81.9 inches

The second side = 7x

= 7 × 9.1

= 63.7 inches

The third side = 5x

Let x represent the hourly daytime rate and y represent her hourly nighttime rate.

The system of equations is

12 x + 4 y = 120……………(1)

4 x + 3 y = 60……………(2)

We have to find the solution to the system of equations.

To find the solution for the system of equation we solve the given equation using elimination method.

Multiply equation by 3 on both sides, we get;

12x + 9y = 180

Subtract equation 3 and 1

12x+9y-(12x+4y)=180-120

12x+9y-12x-4y=60

5y=60

Divide by 5 on both side, we get;

y=12

Step-by-step explanation: did edge test

The required value of n for two similar pentagons is 15/4.

The scale factor is a type of measurement which is used to increase or decrease the size of an object keeping its shape as the same. It can be determined by taking the ratio of the new and the original dimension of the object.

The given two pentagons have similar shape because one has been scaled to get the other.

It implies that the ratio of the corresponding sides for them will be equal. It can be written as follows,

5/n = 3(¹/₃)/2(¹/₂)

=> 5/n = (10/3)/(5/2)

=> 5/n = 20/15

=> n = 15/20 × 5

There are 1000 milliliters in one liter, so a two-liter bottle contains 1000 * 2 = 2000 milliliters of milk. Since one cup contains approximately 250 milliliters, a two-liter bottle contains 2000 / 250 = 8 cups of milk. Rounding this value to the nearest tenth, we find that there are approximately 8.0 one-cup servings of milk in a two-liter bottle.

A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable). In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences. A "vertical line test" can be used when examining a graph to determine whether a relation is a function. The relation is not a function if any point on the graph may be used to build a vertical line that crosses the relation twice.

Step-by-step explanation:

If you draw multiple vertical lines through each graph, C is the only graph that touches the line once. Which means it passes the vertical line test.

The equations that represent the line are:

B. 2x + 3y = –3

D. y + 3= –2/3(x – 3)

E. y – 1 = –2/3(x+3)

An equation that represents a line whose slope is given as m, and it intercepts the y-axis at b, is expressed in slope-intercept form as y = mx + b.

To find the equation of the given line above, pick two points on the line, (0, -1) and (-3, 1) and find the slope (m):

Slope of the line (m) = change in y / change in x = (1 - (-1)) / (-3 - 0)

Slope of the line (m) = 2 / -3

Slope of the line (m) = -2/3.

The line intercepts the y-axis at -1. This means the y-intercept of the line is b = -1.

To write the equation of the line, substitute m = -2/3 and b = -1 into y = mx + b:

y = -2/3x - 1

It can be rewritten as 2x + 3y = –3 in standard form, or as y + 3= –2/3(x – 3) or y – 1 = –2/3(x+3) in point-slope form.
