Which equation has a constant of proportionality equal to 1? Choose 1 answer: A y 10 1 11 B y 7 8 3 y = 15 D y = 2

The most appropriate unit for Nathan to use instead of centimeters per minute is centimeters per year.

An earthquake simply means a rapid motion of the solid layer of the Earth.

In this case, Nathan told his brother that up until a 7.8-magnitude earthquake hit Nepal in 2015, Mount Everest had been moving northeast at a rate of 7.7×10^-6 centimeters per minute.

Since the year is being discussed, the unit should be based on the year.

Answer:

a.

Fee of whole band = Fee of writer + guitarist + singer

Fraction of fee of whole band = 4/12 + 1/12 + 1/12

= 4+1+1/12

=6/12

=1/2

b.

Fee of writer= 4/12 of £3000

=3000 × 4/12

= £1000

Fee of singer= 1/12 of £3000

= 3000 × 1/12

= £250

Fee of guitarist= Fee of singer

= £250

Answer:

2S-a1n/n

Step-by-step explanation:

S = n(a1 + an)/2

2S = n(a1 + an)

2S = na1 + nan

nan = 2S - na1

an = (2S - n a1)/n

The distance remaining is given by the equation d = 270 - 60t

Speed is the ratio of distance travelled to time taken. It is given by:

Speed = distance / time

Let d represent the distance from Las Vegas to Los Angeles and t represent the remaining time after departure.

A car travels from Las Vegas to Los Angeles at about 60 mi/h. The distance from Las Vegas to Los Angeles is 270 miles.

Hence distance remaining is:

d = 270 - 60t

The distance remaining is d = 270 - 60t

Given data:

The given expression can be written as,

Thus, the option (c) is correct.

Measure of CAB is 84.4, by using supplementary angle theory.

In geometry, two angles are referred to as supplementary angles if their sum is 180 degrees. For instance, if A + B = 180°, then A and B are considered supplementary angles. Complementary angles always result in a straight angle when combined (180 degrees).

Angles that add up to a precise 90 degree angle are said to be complementary. For instance, 30 degrees and 60 degrees are complementary angles.

We have given, CAB= 4x+14 and DAB = 6x-18

Both are supplementary angle

Therefore, CAB + DAB = 180

4x+14+6x-18=180

10x-4=180

10x=176

x=17.6

hence, CAB = 4(17.6)+14 = 84.4

Answer:  Table A has a proportional relationship

See the diagram below

==================================================

Explanation:

Table A has a proportional relationship because all the points are on the same straight line. That line in this case is y = 2x

Whatever x is, multiply it by 2 and you'll get the y value

Example: If x = 4, then y = 2*x = 2*4 = 8 which gives the point (4,8)

Another phrase for "proportional relationship" is "direct variation".

By Angle-Angle theorem similarity ΔABC is similar to ΔA'B'C'.

Given two triangles are ABC and A'B'C'.

Dilation is the process of resizing or transforming an object. It is a transformation that makes the objects smaller or larger with the help of the given scale factor. The new figure obtained after dilation is called the image and the original image is called the pre-image.

1) Triangle ABC is reduced to triangle A'B'C'

∠ABC=∠A'B'C'=90°

∠BAC=∠B'A'C'

So, by AA similarity

ΔABC≈ΔA'B'C'

2) Triangle ABC is enlarged to triangle A'B'C'

∠ABC=∠A'B'C'

∠BAC=∠B'A'C'

So, by AA similarity

ΔABC≈ΔA'B'C'

Therefore, by Angle-Angle theorem similarity ΔABC is similar to ΔA'B'C'.

Answer:

Step-by-step explanation:

The complete statement is:

This can be rewritten as _f(x)_ = 3x - 2, since y can be replaced with _f(x)__.

A general relation is written as:

y = something that depends of x.

This is a relation that relates the variable y with the variable x, where we define x as the input and y as the output.

If this is a function, we can use the notation:

y = f(x).

(or any letter of x, f(x) is the most common notation used)

in this case, we have:

y = 3x - 2

And in function notation, this will be writen as:

The graph that represents the system of inequalities is the graph attached below.

The graph that would represent the system of inequalities must be two lines that intersect each other and have the exact slope and y-intercept of each of the lines on the graph.

Determine the slope and y-intercept of each of the inequalities, and also determine their boundary lines based on which inequality sign they have.

The line that represents the inequality, y ≥ ½x + 1, will be a solid line that has a slope of ½, and a y-intercept of 1.

The second line that represents the inequality, y ≥ -x - 2, will be a dashed line that has a slope of 1, and a y-intercept of -2.

The number of rankings that are possible when the company has 40 salespeople is 78960960.

Based on the information given, permutations will be used. The formula is illustrated thus:

Permutations = n! / (n – r)!

N is the number of things you are choosing from,

r is the number of items.

“!” is a factorial of a number

The company has 40 salespeople and the board member at the company asks for a list of the top 5. This will be;

The number of pounds and ounces that we have in 134 ounces is; 8 pounds 6 ounces

We know that in units conversion, there are different units and their conversion rates. For example;

1 meters = 100 cm

1000 meters = 1 kilometer

1000 grams = 1 kilograms

100 cents = 1 dollar

Now, we want to convert ounces to pounds.

The conversion rate for ounces to pounds is;

1 ounce = 0.0625 pounds

We are given 134 ounces of cold cuts for a party. Converting that to pounds gives us;

134 * 0.0625/1 = 8.375 pounds

Solution: X-value of vertex=-3

Y-value of vertex=-4

Zeros of the parabola: X=-5 and x=-1

Analysis

We can find the x-coordinate of the vertex, calculating -b/2a. First, we identify the a and b values of y=ax^2+bx+c of your quadratic equation.

b=6

a=1

Now, let's find the zeros of the parabola. We factorize the quadratic equation:

For this type of probability question, there are different ways to solve the same question but let's analyze the situation and calculate as simple as possible.

For our question, there are two parts, the first one first is the probability to pick someone who is a woman. Once there are 60 people of which 30 are women, it means this probability is 30/60. Let's keep this probability.

Now let's move on to the second part. The situation where we pick someone who is without a date. once there are 60 people and all 30 women have a date and 16 men also have a date it means 30 + 16 - 60 = 14 people does not have a date. So the probability to pick someone without a date is 14/60.

Now once we have analyzed the two parts of the question, and we have two probabilities all we need is to sum our probabilities, as follows:

But why do we sum and do not multiply? Because we use the proposition OR at "Find the probability of picking someone at random and getting a person who is a woman OR without a date" If the proposition was AND we would have multiplied both probabilities.

The solution for the inequality is 11.746 ≤ x ≤ 24.44

Kali earns a 15.75 plus a flat fee of 50 from her job.

She wants to earn between 200 and 400.

Let 'x' denote her earning potential.

Then the inequality for her earning potential is given by,

200 ≤ 15.75x + 50 ≤ 400

We solve this inequality for x.

Subtract 50 from the inequality,

⇒ 200 -15 ≤ 15.75x ≤ 400 -15

⇒ 185 ≤ 15.75x ≤ 385

Divide by 15.75,

⇒ 11.746 ≤ x ≤ 24.44

Using the congruency of the triangle we can prove all the conditions.

The dimensions of the sides and angles of two or more triangles determine whether they are congruent. A triangle's size and shape are determined by its three sides and three angles, respectively. Two triangles are said to be congruent if pairings of corresponding sides and corresponding angles are equal. They are the exact same size and form.

D is the midpoint of AC

so AB = BC

and also AD = CD

so the triangle ADB is congruent to triangle CDB

The length of the sloping side of the roof is 23.3 feet.

Given the equation:

y = 828000 - 2700x

Where y is the value of the building and x is the number of months of use.

Let's find when the value of the building will be $666,000.

To find when the value will be $666,000, substitute 666000 for y in the equation and solve for x.

y = 828000 - 2700x

666000 = 828000 - 2700x

Subtract 828000 from both sides:

666000 - 828000 = 828000 - 828000 - 2700x

-162000 = -2700x

Divide both sided by -2700:

The value of the building will be $666,000 after 60 months.

Now, let's convert from months to years.

Where:

12 months = 1 year

Therefore, the value of the building will be $666,000 after 5 years.
