Answer 1
There's a lot going on, but the main thing to focus on really is the equation 
AE+EB = CF+FD

and on the equation 
EB = CF

Because the second equation (shown above) is true, we can effectively replace the "EB" with "CF" like so
AE+EB = CF+FD
AE+CF = CF+FD

Then we can subtract CF from both sides
AE+CF = CF+FD
AE+CF-CF = CF+FD-CF
AE = FD

When I subtracted CF from both sides, I used the Subtraction Property of Equality, which is the answer needed to go into the blank.

When the blue trapezoid is translated to the green one, the new coordinates of the point (0, 0) will be



A) (-6, -2).

B) (-2, -8).

C) (-8, -6).

D) (-6, -8).

Answers

ur point (0,0) on the blue shape, when translated to the green shape, becomes (-6,-8)

Answer:  The correct option is (D) (-6, -8).

Step-by-step explanation:  we are given to find the new co-ordinates of the point (0, 0) when  blue trapezoid is translated to the green one in the figure.

As shown in the given figure, to translate blue trapezoid to green one,

the x-coordinate of each vertex of blue trapezoid is decreased by 6 units,

and

the y-coordinate of each vertex of blue trapezoid is decreased by  8 units.

So, the new co-ordinates of the point (0 0) becomes

(0, 0)  ⇒  (0-6, 0-8) = (-6, -8).

Therefore, the new co-ordinates of the point (0 0) are (-6, -8).

Thus, (D) is the correct option.


Graph the image of the given triangle, reflected across the y-axis for 2.

Graph the image of the given triangle after the transformation that has the rule (x, y)→(x, −y) for 3.

Answers

Question 1:

The rule (x, y) → (x+2, y-4) represents a translation 2 units RIGHT and 4 units DOWN. We know it's translated right from x + 2 (this is a translation across the horizontal axis) and it's translated down from y - 4 (this is a translation across the vertical axis).

Question 2:
Refer to the first diagram attached below

Question 3:
Refer to the second diagram attached below

Question 4:
We first need to work out the sum of angle in a pentagon, using the formula:

Sum of interior angles = (number of sides - 2) × 180°
Sum of interior angles = (5 - 2) × 180
Sum of interior angles = 3 × 180
Sum of interior angles = 540°

Then we set up an equation:
121° + 108° + 102° + 100° + x = 540°
431° + x = 540°
x = 540 - 431 = 109°
---------------------------------------------------------------------------------------------------------------

Question 5

Exterior angles of a polygon add up to 360°
We are assuming that the 13-sided polygon is a regular polygon, meaning all sides of the same length.

The size of one exterior angle = 360° ÷ 13 sides = 27.7° (to the nearest tenth)

In a lottery, a 4 digit number from 0000 to 9999 is randomly selected. Find the probability that the number selected begins with a 3 and ends in a 2 or 0.

Answers

Since the choices is from 0000 to 9999, therefore there are a total of 10,000 possibilities.

 

The possibilities that the number begins with a 3 and ends in a 2 or 0 is:

possibilities = 1 * 10 * 10 * 1 + 1 * 10 * 10 * 1 = 200

 

Therefore the probability is:

P = 200 / 10,000 = 0.02 = 2%

 

So there is a 2% probability.

Final answer:

The probability that a randomly selected 4-digit number begins with a 3 and ends with a 2 or 0 is 0.0200 or 2%.

Explanation:

To find the probability that a randomly selected 4-digit number begins with a 3 and ends in a 2 or 0, we can use the rule of product for independent events. Since the first digit must be 3, there is one choice for the first digit. For the second and third digits, they can be any number from 0 to 9, so we have 10 choices for each. The last digit can be either 2 or 0, which provides 2 possibilities.

Thus, the total number of favorable outcomes is 1 (for the first digit) × 10 (for the second digit) × 10 (for the third digit) × 2 (for the last digit) = 200 favorable outcomes. The total number of possible 4-digit numbers is 10000 (ranging from 0000 to 9999).

So the probability is calculated as the number of favorable outcomes divided by the number of total possible outcomes: Probability = 200 / 10000 = 0.02. After rounding to four decimal places, as instructed, the probability is 0.0200 or 2%.

The measure of the value 'x' for the supplementary angles will be 22. The correct option is D.

What are supplementary angles?

If two angles add up to 180 degrees, they are said to be supplementary angles. When supplementary angles are combined, they form a straight angle (180 degrees).

In other words, if Angle 1 + Angle 2 = 180°, angles 1 and 2 are supplementary. Angles 1 and 2 are referred to as "supplements" in this case.

The measure of the value x will be calculated as:-

5x + 20 + 50 = 180

5x + 70 = 180

5x = 180 - 70

5x = 110

Okay. So we'll start off by talking about miles per hour. Me. Castelli drove 125 miles in 2.5 hours. Divide 125 and 2.5 hours and you see that he drove 50 miles (81 kilometers) in one hour. 1,000 meters are in 1 meter, and 1,000 * 81 = 81,000. So he drives 81,000 meters in 1 hour. To find meters per minute, you divide 81,000 by 60, and you'll get 1,350 meters per minute. Here it is written for you to understand it better:

Numbers 1-30 are written on cards and placed in a bag. One card is drawn. Find each probability.

a. drawing an even number or a 1.

b. drawing an even number or a multiple of 7.

Answers

Answer:

A. [tex]\frac{8}{15}[/tex]    There are 15 even number and then there is 1 so 16 possibilities in total.

B. [tex]\frac{19}{30}[/tex]    There are 15 even numbers and there are 4 multiples of 7 so 19 in total.

The question requires calculating the probability of drawing an even number or a 1, and an even number or a multiple of 7 from cards numbered 1 to 30. For the first case, the probability is 16/30 and for the second case, it's 17/30, considering mutually exclusive events and counting each outcome only once.

The question involves calculating the probability of drawing specific cards from a set of numbered cards. To find the probability of a particular outcome, we divide the number of ways that outcome can occur by the total number of possible outcomes.
Probability of drawing an even number or a 1

In the set of numbers 1-30, there are 15 even numbers (2, 4, 6, ..., 30) and one number 1. Since the events 'drawing an even number' and 'drawing a 1' are mutually exclusive, we add the probabilities. There are 16 favorable outcomes (15 even numbers + 1), out of a total of 30 possible outcomes.

Probability = Number of favorable outcomes / Total number of outcomes
= 16/30

Probability of drawing an even number or a multiple of 7

Again, from numbers 1-30, we have 15 even numbers. The multiples of 7 up to 30 are 7, 14, 21, and 28. Of these, 14 and 28 are also even numbers and have already been counted. Therefore, we have 2 additional unique multiples of 7 (7 and 21) to consider. Thus, there are 17 favorable outcomes (15 even numbers + 2 unique multiples of 7).

Probability = 17/30

The weekly demand and supply functions for Sportsman 5 × 7 tents are given by
p = −0.1x^2 − x + 33
p = 0.1x^2 + 2x + 13
respectively, where p is measured in dollars and x is measured in units of a hundred. Find the equilibrium quantity. Find the equilibrium price.

Answers

To find the equilibrium quantity and price for tents, we equated the demand -0.1x² - x + 33 with the supply 0.1x² + 2x + 13, solved the equation, and found the equilibrium quantity to be 500 units and the equilibrium price to be $25.50.

To find the equilibrium quantity and price for the Sportsman 5 x 7 tents, we need to set the demand function equal to the supply function.

Demand function: p = -0.1x² - x + 33
Supply function: p = 0.1x² + 2x + 13

Setting them equal to each other:

-0.1x² - x + 33 = 0.1x² + 2x + 13

Now, combine like terms to solve for x:

-0.1x² - 0.1x² - x - 2x + 33 - 13 = 0

-0.2x² - 3x + 20 = 0

To find the equilibrium quantity x, we solve this quadratic equation.

By dividing the entire equation by -0.2 to simplify:

x² + 15x - 100 = 0

The factored form of the equation is (x + 20)(x - 5) = 0, this yields two solutions for x: x = -20 (which we dismiss as a negative quantity that does not make sense in this context) and x = 5. Therefore, the equilibrium quantity is 5 (in hundreds of units).

To find the equilibrium price, substitute x = 5 into either the demand or supply function:

p = -0.1(5)² - (5) + 33

p = -2.5 - 5 + 33

p = 25.5

So the equilibrium price is $25.50.

Write a function rule for that table.

Final answer:

To find the value of x, the student needs to set up an equation based on the sum of angles in a triangle, which is given as 175 degrees. The algebraic expressions for the other angles are used to establish the equation, which is solved for x, resulting in x = 5.

Explanation:

The student is asking for help with a geometric problem where the sum of the measures of angles in a triangle is given along with two algebraic expressions for the other angles. The fact that the angles add up to 175 degrees helps us establish an equation: mVUT = mVUJ + mJUT. Substituting the given values, we get 175 = (17x-3) + (17x+8). Simplifying this, we get 175 = 34x + 5. Subtracting 5 from both sides, we get 170 = 34x. Dividing both sides by 34, we find that x = 170 / 34, which simplifies to x = 5. Therefore, the value of x is 5.

The percent of 52 which result in 12 would be 23%.

How to find the percentage from the total value?

Suppose the value of which a thing is expressed in percentage is "a' the percent that considered thing is of "a" is b%. Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts.

We need to find the percent of 52 which result in 12.

Let the unknown number is represneted by b.

It can be written as;

52% x b = 12

either way, u get the same answer

To find the total price of an item including sales tax, convert the tax rate to a decimal and multiply by the item's cost. The total cost for a $2.50 snack combo with an 8% tax is $2.70.

The question involves calculating the total price of an item including sales tax. To find the total cost including tax, we need to first figure out the amount of sales tax by converting the tax rate from a percent to a decimal. Then, we will multiply this decimal by the initial cost of the item to get the tax amount.

Here's a step-by-step explanation using the provided example:

Convert the sales tax rate from a percent to a decimal: 8% as a decimal is 0.08.Multiply the decimal tax rate by the cost of the item: 0.08 \\times $2.50 = $0.20.Add the tax to the initial cost to get the total price: $2.50 + $0.20 = $2.70.

Therefore, the total price of the snack combo including an 8% sales tax is $2.70.
