DOES ANYONE KNOW THE ANSWER??!

Answer:

By comparing the ratios of sides in similar triangles ΔABC and ΔADB,we can say that [tex]x^{2} =pz[/tex]

Step-by-step explanation:

Given that ∠ABC=∠ADC, AD=p and DC=q.

Let us take compare Δ ABC and  Δ ADB in the attached file , ∠A is common in both triangles

                                                                     and given ∠ABC=∠ADB=90°

Hence using AA postulate, ΔABC ≈ ΔADB.

Now we will equate respective side ratios in both triangles.

[tex]\frac{AB}{AC}= \frac{AD}{AB}=\frac{BD}{BC}[/tex]

Since we don't know BD , BC let us take first equality and plugin the variables given in respective sides.

[tex]\frac{x}{z}= \frac{p}{x}[/tex]

Cross multiply

[tex]x^{2}=pz[/tex]

Hence proved.

Step-by-step explanation:

fred has 2 peanut butter and 3 jelly

type 1 peanut butter can go with all three types of jelly = 3 pb&js where ther is one constant peanutbutter and 3 different jellys

type 2 peanut butter can go with all three jellies = 3 pb&js where there is one constant peanutbutter and 3 different jellies

3+3=6

there are 6 peanut butter and jelly sandwhiches he could make.

you can also just multiply the numbers (2x3=6)

Final answer:

Fred can make 6 different peanut butter and jelly sandwiches by multiplying the number of peanut butter types by the number of jelly types (2 types of peanut butter × 3 types of jelly). The type of bread does not affect the count as there's only one type.

Explanation:

To determine how many different peanut butter and jelly sandwiches Fred can make, we need to consider all possible combinations of peanut butter, jelly, and bread. Since Fred has two types of peanut butter, three types of jelly, and one type of bread, the number of different sandwich combinations can be calculated using the Counting Principle. This principle states that if there are n ways to do one thing, and m ways to do another, then there are n × m ways to do both.

In Fred's case, for every type of peanut butter, he can choose from three different types of jelly. So, for two types of peanut butter, we have:

2 types of peanut butter × 3 types of jelly = 6 combinations

Since there's only one type of bread, it doesn't change the number of combinations.

Therefore, Fred can make 6 different peanut butter and jelly sandwiches.

Step-by-step explanation:

Hello!

To find the closet number we first need to understand how our data, and how to find the mean.

The mean is known as the average, which we find when we add all of our data up and divide by the number of factors.

In this case, after reading our graph, our data set is equal to:

3,4,4,4,4,5,5,5,5,5,6,6,6,6,7,7,8,9,10,11

When all of these numbers are added we get = 120

120 divided by 20 (the total number of factors) is equal to 6!

Which means that the answer to this question is E. 6

Hope this helps.

Based on the calculations, a number which is closest to the mean of this distribution is equal to: E. 6.

A mean is also known as arithmetic average and it's a ratio of the sum of the total number in a data set to the frequency of the data set.

Mathematically, the mean for this data set would be calculated by using this formula:

Mean = [F(x)]/n

For the total number of data, we have:

F(x) = 3 + 4 + 4 + 4 + 4 + 5 + 5 + 5 + 5 + 5 + 6 + 6 + 6 + 6 + 7 + 7 + 8 + 9 + 10 + 11

F(x) = 120.

Substituting the parameters into the formula, we have:

Mean = [F(x)]/n

Mean = [120]/20

Mean = 6.

The slope-intercept form: y = mx + b

We have in point-intercept form: y - 5 = 6(x + 1)

Transform:

y - 5 = 6(x + 1)     |use distributive property

y - 5 = (6)(x) + (6)(1)

y - 5 = 6x + 6     |add 5 to both sides

y = 6x + 11

The equation of required line in slope intercept form is y= 6x + 11 First option is correct

What is equation of line in slope intercept form?

The most general form of equation of line in slope intercept form is given by y = mx + c Where m is the slope of the line and c is the y intercept of the line. Slope of a line is the tangent of the angle that the line makes with the positive direction of x axis. If  [tex]\theta[/tex] is the angle that the line makes with the positive direction of x axis, then slope (m) is given by m =  [tex]tan\theta[/tex]

The distance from the origin to the point where the line cuts the x axis is the x intercept of the line.

The distance from the origin to the point where the line cuts the y axis is the y intercept of the line.

Here,

[tex]y - 5 = 6(x + 1)\\y - 5 = 6x + 6\\y = 6x + 6 + 5\\y = 6x +11[/tex]

y= 6x + 11 is the equation written in slope intercept form. First option is correct

Rewrite the inequality as

[tex] w<12 [/tex]

by adding 4 to both sides.

So, you want to pick only the values that are strictly less than 12, i.e. all of the values except 13.

Dividing:-   (1.75 * 10^18) / (6.25 * 10^15)

=  (1.75 / 6.25) * (10^18 / 10^15)

= 0.28 * 10^3

= 280    Answer

Final answer:

The number of bacteria in petri dish A (1.75×1018) is 280 times greater than the number of bacteria in petri dish B (6.25×1015).

Explanation:

To find out how many times greater the number of bacteria in petri dish A is compared to petri dish B, we divide the number of bacteria in dish A by the number of bacteria in dish B.

Number of bacteria in dish A = 1.75×1018

Number of bacteria in dish B = 6.25×1015

Now, let's divide the two:

(1.75×1018) / (6.25×1015) = (1.75 / 6.25) × 10(18-15)

1.75 divided by 6.25 is 0.28, and 1018 divided by 1015 is 103.

Therefore, 0.28 × 103 = 280. The number of bacteria in petri dish A is 280 times greater than the number of bacteria in petri dish B.

Answer: There are a lot of answers to this product. Some of them include (in the format (w, x), where w is the whole number, and x is the factor you must multiply it by to get 0.24):

(2, 0.12), (3, 0.08), (4, 0.06), (6, 0.04), and so on.

Step-by-step explanation: Well, you could just assign the smallest who number greater than 1 to one of the factors, which is 2. Now you just have to multiply that by another factor to get 0.24. To do this, you could set up an equation like this:

2*x=0.24

Next, you would divide both sides by 2 to cancel out the 2 on the left side of the equation, leaving you with:

x=0.12

There you have it!

Now you can check your work by multiplying 2 and 0.12, and you will get 0.24!

You can do the same thing with other whole numbers, such as 3 and 4, and complete the same process to find the decimal factor that multiplies to 0.24.

Answer:

The larger of the two angles is x, which is 75. y is the smaller angle at 15.

Step-by-step explanation:

In order to find these, we can use our solved value for y in the second equation to plug into the first equation. This method is called substitution.

x + y = 90

x + (1/5x) = 90

1.2x = 90

x = 75

Now we can plug that value into either equation to find y

y = 1/5x

y = 1/5(75)

y = 15

Answer:

1.) 75

So the initial renting fee for you and your friend is $16(8 bucks a piece). Each hour you and your friend will be paying $7 (that's 1.75 for each HALF hour for each of you).  

nal answer:

After subtracting the initial rental cost for two bicycles, the remaining amount spent was divided by the cost per half hour to find the total number of half hours ridden. Each person rode for 3 half hours, which equates to 1.5 hours each.

Explanation:

To calculate how many hours each of you rode a rented bicycle at the bike rental shop, let's break down the charges. The shop charges $8 per person to rent a bicycle and $1.75 for every half hour of ride time. Since there were two of you, the initial cost would be 2 × $8 = $16. The total amount spent was $26.50, so subtracting the initial rental cost, we have $26.50 - $16 = $10.50 left for the actual riding time.

The cost of riding time per person is $1.75 per half hour. So, we divide the remaining amount $10.50 by $1.75 to find the total number of half hours both of you rode combined: $10.50 / $1.75 = 6 half hours. Since this is the combined time for both you and your friend, each of you rode for 3 half hours, or 1.5 hours in total.

He charges 10$ every time he mowed someones lawn

So 110/10=11

He would have to mow his neighbors lawn 11 times.

Answer:

Keegan need to mow 11 times to his neighbors lawn to have enough money to buy the skateboards.

Step-by-step explanation:

Consider the provided information.

It is given that Keegan need $140 and Keegan saved $30. Keegan also charges $10 each time he completes the job writing.

Let x the number of times Keegan needs to mow his neighbors lawn to earn enough money.

Thus the required equation is;

[tex]140=30+10x[/tex]

Now solve the equation as shown below:

[tex]140-30=10x[/tex]

[tex]110=10x[/tex]

[tex]\frac{110}{10}=x[/tex]

[tex]x=11[/tex]

Hence, Keegan need to mow 11 times to his neighbors lawn to have enough money to buy the skateboards.

the value of the digit 5 is 50,000. Think of it as the numbers behind 5 as zeros and you will have the answer.

The answer will be D

n = 2

distribute and simplify left side of equation

50 - 10n - 1 = 29

49 - 10n = 29 ( subtract 49 from both sides )

- 10n = 29 - 49 = - 20

n = [tex]\frac{-20}{-10}[/tex] = 2

To get rid of the parantheses we must multiply 10 by anything inside the parantheses.

10(5-n)-1=29

50-10n-1=29

Combine like terms

50-10n-1=29

49-10n=29

Subtract 49 from both sides

49-10n=29

-10n=-20

Divide both sides by -10

-10n/-10=-20/-10

n=2

Our final answer is 2
