Answer:
AB = 2
Step-by-step explanation:
the triangles are similar so that means there is a constant ratio for each side length. so comparing the ratios from the bigger triangle to the smaller triangle, leaves us with 9/3 and 15/5. if you take those and divide them you get 3 for both of them which is the constant. so then in order to find the length of AB just take the side length of XY (6) and divide it by 3 (the constant ratio) and there you have your answer!
hope this helps.

Trapezoid STUV is similar to trapezoid NOPQ. What is the length of OP?
Answers
Answer:
F. 4 2/3 centimeters
Step-by-step explanation:
since the trapezoids are similar to each other, that means there is a common ratio between them. so taking into consideration the first trapezoid STUV when we compare that to NOPQ, OP comes out to be 4 and 2/3 centimeters. start by comparing the ratio of ST to NO and then move on to TU and then OP.
. Since the pentagon is a regular pentagon, the measure of each interior angle will be the same.
To find the size of each angle, divide the sum, 540º, by the number of angles in the pentagon.

540° ÷ 5 = 108° There are 108° in each interior angle of a regular pentagon.

A pentagon has five sides, thus the interior angles add up to 540°, and so on.
9x + 5 = 4(x + 2) + 5x
solve for X
Answers
Answer:
no solution
Step-by-step explanation:
9x + 5 = 4(x+2) + 5x
9x + 5 = 4x + 8 + 5x
9x + 5 = 9x + 8
9x + 5 can never be equal to 9x + 8, so the answer is no solution
Answer:
x=3
Step-by-step explanation:
9x + 5 =4(x+2) + 5x
9x + 5= 4x + 8+ 5x ( do the parenthesis first- mulitiply 4 and x and get 4x and 4 times 2 = 8)
9x + 5 = 9x + 8 ( add the x's together 4x +5x = 9x )
9x = 9x + 3 ( subtract 5 both sides and you get 3 )
=3 ( subtract 9x from both sides

Spins a fair spinner numbered 1 - 5 and flips a fair coin. What is the probability of obtaining a factor of 15 and a tail?
Answers
Answer:
3/10
Step-by-step explanation:
Probability is the ratio of the number of possible outcome to the number of total outcome.
Given that the fair spinner is numbered 1 - 5, the factors of 15 there are 1, 3 and 5 hence the probability of obtaining a factor of 15
= 3/5
The probability of obtaining a tail from the flip of a coin
= 1/2
Hence the probability of obtaining a factor of 15 and a tail
= 3/5 * 1/2
= 3/10

The total of the shirts and pants is $65.
She bought 9 shirts and 4 pants, which would be 13 shirts and pants.
We then divide the total cost of the shirts and pants, $65 by the total shirts and pants, 13.
65 / 13 = 5
So, each shirt or pants costs $5.

Answers
Answer:
36 cards in each box
Step-by-step explanation:
Let the number of cards in each box be x.
4 * x / 3 = 48 (4 packs of cards, three friends)
x / 3 = 21
x = 36.
Answer:
36 cards in each box
Step-by-step explanation:
Because each friend gets the same amount of cards, there needs to be 48*3 or 144 trading cards in total. There are 4 boxes so in each box there would be 144/4 or 36 cards in total.

Luego de dormir 6 horas al día a usted le quedan 18, que puede repartir entre estudio y ocio. X representa
las horas dedicadas al ocio y la variable Y las horas de estudio. Represente la relación lineal existente entre
las distintas combinaciones posibles de X e Y.
Answers
The linear relationship between the different possible combinations of X and Y is Y= -X + 18.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
We know that after sleeping for 6 hours, there are 18 hours left in a day. These 18 hours can be split between leisure time and study time.
Now,
Let's let X be the number of hours of leisure time, and Y be the number of hours of study time.
Since we know that there are a total of 18 hours,
we can set up the following equation.
X + Y = 18
This equation represents all the possible combinations of X and Y that add up to 18 hours.
Now,
To represent a linear relationship between X and Y.
Y = -X + 18
This equation represents a linear relationship between X and Y.
Where X is the independent variable and Y is the dependent variable.
This is in the form of a slope-intercept form.
y = mx + c
Where m = -1 and c = 18
So,
The slope = -1 and the y-intercept is 18.
Thus,
Y= -X + 18 represents all the different possible combinations of leisure time and study time that adds up to 18 hours.

Answer:
0.30 of a book / hour or 3/10 of a book per hour.
Step-by-step explanation:
Usually I tell people to put the numbers into decimals. Unfortunately for this question, it won't work. So we have any choice but to do it with fractions.
r = amount / time
amount = 1/4
time = 5/6
r = [tex]\frac{\frac{1}{4} }{\frac{5}{6} }[/tex]
Invert the denominator and multiply
r = [tex]\frac{1}{4} * \frac{6}{5}[/tex]
r = 6 * 1 / (5*4) = 6/20 = 3/10
The answer is 3/10 of a book per hour
5/6 of an hour is almost an hour.
1/4 of a book is 0.25 of a book.
3/10 of a book is 0.30 of a book. So it looks like it is just about right.
