The value of the missing variable x in the given triangle is; x = 15

We know that sum of angles on a straight line is 180 degrees. That means the angle on the horizontal line of (9x + 16)° inside the triangle will be;

180 - (9x + 16)°

Now, we know that sum of angles in a triangle is 180 degrees. Thus;

180 - (9x + 16)° + 5x - 14 = 90

180 - 4x - 30 = 90

150 - 4x = 90

150 - 90 = 4x

60 = 4x

x = 60/4

x = 15

the solution is the option A

Answer:

I would say B, because the entire purpose and main theme of  The Interlopers is to show the futility and uselessness of feuds and arguments, and that sometimes its best to just live and let live, just to keep it short.

The given equation is

This equation belongs to an uptrend line because the variable x is positive. The line has to have a y-intercept at -1 because that's the constant term.

Following the characteristics of the equation, we can deduct that the correct graph is A.

This statement is justified by the angle addition postulate.

I used Desmos.

Let's us tabulate the data that is on the scatterplot.

As you can see in the fourth column, "Sold More Trucks than Cars?", some rows say "Yes" and some say "No".

Let's take a look at Employee No.1. Employee No.1 sold 4 trucks and sold 2 cars. Therefore, employee no.1 was able to sell more trucks than cars and thus, the answer to the fourth column is "Yes."

The same is done for all the employees.

In the end, there are 6 employees who were able to sell more trucks than cars.

The given system is

Let's isolate y in the first equation.

Then, we replace the equation we've got in the second equation of the system.

Now, we solve for x.

We use this value to find y.

Answer:

the amount of money sam has borrowed was 2400

he paid interest 2%

total intreast 48$

48÷3 = $16 a year

2%= $16

16×5= $80 for 10%

$80× 10= 800

800×3= 2400 total amount was borrowed

so 2400-2%= 2352

2400- 2352= 48

Answer

The length of the missing leg = 12 m

Explanation

The triangle presented is a right angled triangle because one of its angles is equal to 90 degrees.

The Pythagorean Theorem is used for right angled triangle, that is, triangles that have one of their angles equal to 90 degrees.

The side of the triangle that is directly opposite the right angle or 90 degrees is called the hypotenuse. It is normally the longest side of the right angle triangle.

The Pythagoras theorem thus states that the sum of the squares of each of the respective other sides of a right angled triangle is equal to the square of the hypotenuse. In mathematical terms, if the two other sides are a and b respectively,

a² + b² = (hyp)²

For this question,

Hypotenuse side = 15 m

a = 9 m

b = d = ?

a² + b² = (hyp)²

9² + d² = (15)²

81 + d² = 225

d² = 225 - 81

d² = 144

d = √144

d = 12 m

Hope this Helps!!!

Answer:

We'd use the pythagorean theorem to solve for the other leg's length. As the image suggests, we'd use the theorem,

[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]

If one leg is 9 , that's our a value.

If the hypotenuse is 15 , that's our c value.

Now we just have to find the b value.

Plugging in the variables,

[tex] {9}^{2} + {b}^{2} = {15}^{2} [/tex]

[tex] {9}^{2} = 81 \\ {15}^{2} = 225 \\ 81 + {b}^{2} = 225[/tex]

Subtract 81 from both sides.

[tex] {b}^{2} = 144[/tex]

Square root both sides.

[tex] \sqrt{ {b}^{2} } = b \: and \: \sqrt{144 = 12 } [/tex]

so b = 12

The complete table of the algae area is:

Day 1  2 3 4 5 6

Area 1/2 1 2 4 8 16

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions.

The initial area exists given as;

A(1) = 1/2 square meters

When it doubles every day, we have:

A(n) = 2 × A(n - 1) where A(1) = 2

So, we contain the following values

A(2) = 1/2 × 2 = 1

A(3) = 1 × 2 = 2

A(4) = 2 × 2 = 4

A(5) = 4 × 2 = 8

A(6) = 8 × 2 = 16

Therefore, the complete table is:

Answer:

Perpendicular

Explanation:

Given the coordinates

A(-2,-5), B(4.7) C(0, 2) and D(8,-2)​, we are to determine whether AB is parallel, perpendicular to CD or neither

To do this, we need to find he slope of AB and CD first. Using the formula for calculating slope as shown;

m = y2-y1/x2-x1

For AB:

slope = 7-(-5)/4-(-2)

Slope = 7+5/4+2

Slope of AB = 12/6

Slope of AB = 2

For CD

Slope of CD = -2-2/8-0

Slope of CD = -4/8

Slope of CD = -1/2

Note that for AB to be perpendicular to CD, the product of their slope must be -1.

Given

mAB = 2

mCD = -1/2

Taking their product

mAB * mCD = 2 * -1/2

mAB * mCD = -1

Since the product is -1, hence AB is PERPENDICULAR to CD

x is case of almonds and y is case of walnuts.

Almonds are packaged 15 bags per case and walnuts are packaged 17 bags per case.

H-E-B orders no more than 200 bags of almonds and walnuts at a time.

So,

x + y < 200

where x and y refers to the number of bags

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

H-E-B pays $24 per case of almonds and $27 per case of walnuts, but will not order more than $300 total at any one time.

But keep in mind that : Almonds are packaged 15 bags per case and walnuts are packaged 17 bags per case.

So,

24 * (x/15) + 27 * (y/17) < 300

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

The constraints are:

x + y < 200

(24/15) x + (27/17) y < 300

[tex]10^2[/tex]  and [tex]10^3[/tex] are written in the exponent form.

Exponent

Exponent is defined as the method of expressing large numbers in terms of powers. That means, exponent refers to how many times a number multiplied by itself.

We are given two numbers [tex]7/10^2[/tex] and [tex]7/10^3[/tex].

We have to find the relationship between the two given numbers.

We know that,

[tex]7/10^2[/tex] can be written as 7/100 and [tex]7/10^3[/tex] can be written as 7/1000.

We can write,

7/1000 = (7/100) *(1/10)

Hence, 7/1000 is one-tenth of 7/100.

Also, we can write,

7/100 = (7/1000)*10

Hence, 7/100 is ten times 7/1000.

When two independent temperature readings are subtracted, or when calculating the amount of temperature rise or fall, the result is a temperature difference, also referred to as a delta temperature (T).

We are aware that throughout the course of hours, the temperature dropped from 0 to= [tex]-6\frac{3}{5}[/tex].

Therefore, we will divide the change in temperature by the number of hours to determine the rate of change of the temperature.

In order to solve for that, we shall convert the mixed number into improper fractions.
