If Anne's house is 84 feet long, how long, in inches, should her scale drawing be?

Answer:

Step-by-step explanation: OK so I don't know if I'm exactly right on this  but what I would do is I would first read it more than 1 time and I would see that the sandwich shop offers 4 types of bread, that's 4 different types of bread. Then it says 5 meats, 7 cheeses, 4 condiment options, and you can pick veggies or no veggies. So what I did was I multiplied 4 by 5 and got 20, then I multiplied 7 by 4 and got 28, then I added 20 and 28 and got 48 sandwiches are possible. Then to make sure I was correct I  did 4 times 5 times 7 times 4 by accident and I got 560. So I don't know which one is correct but I just thought that I could at least try to help you because even I have problems with problems like this one too. So I hope I helped you even a little bit.                                      

Create four angles by drawing a straight line that meets another straight line at an angle. To keep track of the angles, assign letters to each one. Make a note of the angles' measurements using a protractor.

A right angle is created when two perpendicular lines cross at an exact 90-degree angle. Four 90-degree right angles are formed by intersecting perpendicular lines.

A right angle is a right angle if one of the four angles created by two intersecting lines is a right angle. Straight lines that are perpendicular to one another intersect at a 90° angle.

As a result, the vertical asymptotes of the function's curve will be at x=-5 and x=1 of quadratic equation .

A function in mathematics is a formula that associates each element from a set (referred to as the domain) with a single element from another set (called the range). A machine that generates an outcome from an input (the independent variable) can be compared to a function (the dependent variable). Algebraic expressions or equations are frequently used to describe functions, such as f(x) = x2 + 3x - 2. In a coordinate plane, where the x-axis denotes the input values and the y-axis denotes the output values, they can also be graphically depicted as a curve or line.

given

Since division by zero is undefined, we must search for the values of x that cause the denominator of the function to equal zero in order to determine the vertical asymptote of a rational function.

The function is undefined at x=-5 and x=1 because the denominator of f(x) = (x-2)/(x2+4x-5) is a quadratic equation that can be factored as (x+5)(x-1).

As a result, the vertical asymptotes of the function's curve will be at x=-5 and x=1 of quadratic equation .

By the hypotenuse-leg congruence theorem (HL theorem), triangles ABD and CBD are congruent.

What is Trapezoid ?

A trapezoid is a four-sided polygon with at least one pair of parallel sides. It is also known as a trapezium in some countries.

To prove that BD is congruent to AC, we will use the fact that the opposite sides of a trapezoid are parallel.

Since AB and CD are parallel, and BC is a transversal, we know that angles ABC and DCB are supplementary (they add up to 180 degrees).

From the given information, we know that angle ABC is congruent to angle DCB. Therefore, both angles must be equal to 90 degrees (since their sum is 180 degrees).

Now consider the right triangles ABD and CBD.

In triangle ABD, we have a right angle at angle ABD, and we know that AB is congruent to CD (given).

In triangle CBD, we have a right angle at angle BCD, and we know that BC is congruent to BC (reflexive property).

We also know that angle ABD is congruent to angle BCD (since they are both equal to 90 degrees minus angle ABC/DCB).

Therefore, by the hypotenuse-leg congruence theorem (HL theorem), triangles ABD and CBD are congruent.

This means that BD is congruent to AC (the corresponding sides of congruent triangles are congruent).

Therefore, we have proven that BD is congruent to AC in trapezoid ABCD.

The answer for x - 10y = 14/3.

To solve for x and y, we can use the first equation to solve for y in terms of x:

-3y = 1

y = -1/3

Now we can substitute this value of y into the second equation and solve for x:

11y - x = -5

11(-1/3) - x = -5

-x = -5 + 11/3

-x = -4/3

x = 4/3

Now that we have found the values of x and y, we can substitute them into the expression x - 10y:

x - 10y = (4/3) - 10(-1/3)

x - 10y = 4/3 + 10/3

x - 10y = 14/3

Therefore, x - 10y = 14/3.

The student's percentile will be 28.

Calculating percentiles is a common practise. The majority of the time, we can define percentile as a score below which a predetermined percentage of other scores fall. We might be able to tell when someone received a test score of 65 out of 90. But without knowing what percentile he belongs to, this number is meaningless. When a score is in the 90th percentile, it signifies that it is higher than the scores of 90% of test-takers.

Given : Student's rank = 144 out of 200

So, there are 56 (200-144) students whose rank is below that student.

We know that, percentile

= no. of ranks below that rank / total no. of ranks * 100

The solution of the equation by factoring is x = 6.645 and x = 1.355.

The breaking or breakdown of an entity (such as a number, a matrix, or a polynomial) into a product of another entity, or factors, whose multiplication results in the original number, matrix, etc., is known as factorization or factoring in mathematics. An algebraic expression is factorised when it is written as the product of its factors. Certain variables, factors, or algebraic expressions might be present.

The given equation is:

x² - 8x + 16 = 7

x² - 8x + 16 - 7 = 0

x² - 8x + 9 = 0

Using the quadratic formula we have:

x = 8 ±√(8)² - 4(1)(9) /2(1)

x = 8 ± 5.29/2

x = 8 + 5.29/2 and x = 8 - 5.29/2

x = 6.645 and x = 1.355

Hence, the solution of the equation by factoring is x = 6.645 and x = 1.355.

The speed of both car A and car B are the same which is 0.7 miles per minute

An equation is an expression containing numbers and variables linked together by mathematical operations such as addition, subtraction, division, multiplication and exponents.

Let x represent the distance travelled by car A and y represent the distance travelled by car B

Speed of car A = x /20

Car B reaches in 50 minutes, hence:

Speed of car B = y/50

Since both speed are same;

x/20 = y/50

20y = 50x    (1)

Car B is 21 miles farther, then:

y - x = 21     (2)

x = 14, miles y = 35 miles

Speed of car A = speed of Car B = 14/20 = 35/50 = 0.7 miles per minute

An object's size in real life and its size on a map or a blueprint are compared using a scale factor, which is a mathematical concept. The scale factor may exceed, fall short of, or be equal to 1.

The size of the object is decreased and becomes smaller if the scale factor is between 0 and 1. This is so because the scale factor only approximates the object's true size. The size of the thing on the map will be half that of the real object, for instance, if the scale factor is 0.5.

When the scale factor is 1, the object's size is said to remain constant. As a result, the map or blueprint is created using the same dimensions.

In other words, the map or blueprint is created at the exact same scale as the final product.

The size of the thing is enlarged and made larger if the scale factor is greater than 1. This is so because the scale factor is a multiple of the object's actual size. The size of an object on a map will appear twice as large as it is in reality, for instance, if the scale factor is 2.

In general, it's crucial to comprehend scale variables in order to appropriately depict an object's size on maps, blueprints, and other scaled representations.

The height of the right rectangular prism aquarium is 7 inches

We can use the formula for the volume of a right rectangular prism to find the height of the aquarium.

The formula is V = l x w x h,

Where V is the volume, l is the length, w is the width, and h is the height.

In this case, we know that the volume of the aquarium is 1120 cubic inches, the length is 20 inches, and the width is 8 inches.

Therefore, we can write:

1120 = 20 x 8 x h

Simplifying the right side of the equation, we get:

1120 = 160h

Dividing both sides by 160, we obtain:

h = 1120/160 = 7
