How does the image triangle compare to the pre-image triangle?
A triangle undergoes a sequence of transformations.
First, the triangle is dilated by a scale factor of 1/3 about the origin. Then the triangle is reflected over the x-axis. Finally, the triangle is translated left 3 units and up 2 units.
Dr. Benton just got his PhD, and he wants to print copies of his thesis in hardcover book format. He could use Middletown Printing, paying a setup fee of $39 and $3 for every book printed. Alternately, he could go through Oxford University, paying an up-front fee of $35 and $5 per book. It turns out that, given the number of books Dr. Benton wants to print, the two options cost the same amount. How many books is that? What is the amount?

20% of the cross-country runners in
a school team weigh between 60 kg
and 70 kg. If 4% of the school of 1125 students are in the cross-country team, how many students in the team weigh between 60kg and 70kg ?
Answer:
9 students
Step-by-step explanation:
First find the amount of cross-country team students, 4% * 1125 = 45
Then 20% * 45 = 9, so 9 students in the team weigh between 60 and 70 kilos.

7. Which transformation of (x, y) is a dilation? (TEKS G.3.A)
F (3x, y)
G (-y, x)
H (3x, 3y)
J (x + 3, y + 3)
Answer:
H (3x,3y)
Step-by-step explanation:
Dilation is a transformation when figure is enlarged or reduced by scale factor. During dilation, every point of preimage is dilated by scale factor, so it means each coordinate of that point must be multiplied by scale factor.
Hence, H(3x,3y) can be the result of dilation with scale factor of 3.

Susan saw birds and mice eating seeds on the ground. She counted 14 heads. 40 legs in total. how many birds and mice are on the ground
Answer:
Birds = 8
Mice = 6
Step-by-step explanation:
Conditions
Let the birds = x
Let the mice = y
Equations
x + y = 14
2x + 4y = 40
Solution
Using the top equation solve for x
x = 14 - y
Use this result to substitue for x
2(14 - y) + 4y = 40
Remove the brackets
28 - 2y + 4y = 40
Combine
28 + 2y = 40
Subtract 28 from both sides
28 - 28 + 2y = 40 - 28
2y = 12
Divide by 2 on both sides
2y/2 = 12/2
y = 6
Solve for x
x + y = 14
x + 6 = 14
Subtract 6 from both sides
x + 6 - 6 = 14 - 6
x = 8
Answer:
7 mice and 7 birds
Step-by-step explanation:
14 heads would mean there are 14 animals in total, as each animal has one head.
Birds have two legs, and mice have four.
2+4=6
40/6=6.67 (recurring)
6.67*2=13.3 (recurring)
6.67*4=26.67 (recurring)
Animal legs can't be in decimal numbers, so we can round the numbers.
13.3 becomes 13, 26.67 becomes 27.
13+27=40
Now we can see that there are 13 bird legs and 27 mice legs.
Divide the bird legs by 2 to get 6.5
Divide the mice legs by 4 to get 6.75
Again, we can't have a decimal of an animal, so we can round.
6.5 becomes 7, and 6.75 also becomes 7.
Therefore, there is 7 of each type of animal.
The formula used to convert degrees Celsius to degrees Fahrenheit is
F=C+32.
Convert 59°F to degrees Celsius. Solve the formula for C, and then use it to
convert the temperature.
Which is the correct formula and conversion?
OA. C=F-32; conversion: 59°F = 135°C
OB. C= (F-32); conversion: 59°F = 15°C
OC. C= (F-32); conversion: 59°F = 106°C
OD. C=F-32; conversion: 59°F = 15°C
The formula to convert degrees Fahrenheit to Celsius is:
[tex]\bf{^{\circ}C=\dfrac{5}{9}(^{\circ}F-32) \ \ \to \ \ \ Formula }[/tex]
Convert 59°F to degrees Celsius.
Add the number 59 in the formula, and solve.
[tex]\bf{=\dfrac{5}{9}(59-32) }[/tex]
Subtract 32 from 59.
[tex]\bf{=\dfrac{5}{9}(27) }[/tex]
Multiply 5 x 9 = 135, then divide 135/9 = 15.
[tex]\bf{=15 \ ^{\circ}C}[/tex]
Therefore 59 °F = 15 °C. The correct option is "D".
{ Pisces04 }Which classification best represents a triangle with side lengths 6 cm, 10 cm, and 12 cm?
acute, because 62 + 102 < 122
acute, because 6 + 10 > 12
obtuse, because 62 + 102 < 122
obtuse, because 6 + 10 > 12
Answer:
obtuse because 6^2+10^2<10^2
Step-by-step explanation:
The given triangle whoe sides are 6cm, 10cm, and 12cm is an obtuse triangle and it can be determine by using pythagorian theorem, i.e. 6^2 + 10^2 < 12^2.
What is Pythagorean theorem?Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a^2 + b^2 = c^2.
here, we have,
Given :
The side lengths of a triangle are: 6cm, 10cm, and 12cm.
Pythagorian theorem can be used to find out that the triangles are acute or obtuse. According to pythagorian theorem, the sum of square of shorter side is equal to the square of the third side of the right angle triangle.
According to pythagorian theorem:.
That is, H^2 = P^2 + B^2.
There are some rules to find the triangle is obtuse or acute:
If H^2 > P^2 + B^2, than the triangle is obtuse.
If H^2 < P^2 + B^2, than the triangle is acute.
Now, applying pythagorian theorem:
we get,
6^2 + 10^2 = 12^2
136 = 144
Here, it is clearly observe that 136 < 144, i.e. 6^2 + 10^2 < 12^2 therefore, the triangle is obtuse.

The area of the playground of dimensions 18 and 240is 432 [tex]m^{2}[/tex].
Given If the dimensions of the playground in the layout are given by 180 cm x 240 cm.
The area of rectangle is length *breadth.
The given playground is in the shape of rectangle because there are two sides given and both the sides are different. In a rectangle length of opposite side found to be equal and each side form an angle of 90 degree.
Area=length*breadth

1.Create a sample space and find the product of each combination. What is the probability that a person wins the game? Express your answer as a fraction in lowest terms and as a percent rounded to the nearest tenth.
(answer to this one is 9/28 and 32.1%)
2. You realize a short time into the carnival that you don’t have enough prizes to last the entire event. You call your teacher, and she suggests that you change the winning number so that a participant will win only 25% of the time. What number will that be? Support your answer.
3. Participants achieving a winning score of 36 or higher in four consecutive attempts will receive a large prize! What is the probability of this occurring?
4. After changing the game rules, participants and the crowd are disappointed when the first five games yield scores of 12, 18, 30, 28, and 24. What statement can you recommend the teacher posts to reassure everyone that the game is fair?
Going by the rules of the game to pick a random card and then multiply it by a roll of a number cube, we can find that:
The probability a person wins a game is 3/8 or 37.5%.For a participant to win 25% of the time, they needs to get 32 or higher. The probability of a score of 36 or higher in 4 consecutive attempts is 1/1,1296.Teacher should tell people that just as the lower numbers could be picked, the products that are 32 or higher can be picked as well.What sample space represents the data?If the die is rolled, it will land on a number between 1 and 6 while there are only four cards that can be picked.
The sample space is:

The frequency table shows that to get 28 or more, a person will have a relative frequency of:
= 1 + 2 + 1 + 1 + 1 + 1 + 1 + 1
= 9
Probability is:
= 9 / 24
= 3/8
= 37.5%
How can a person win only 25% of the time?The number of products required to win 25% of the time is:
= 25% x 24
= 6
To find the winning number, count down from the highest product 6 times to get 32.
What is the probability that a player wins a large prize?The probability of getting 36 or higher is:
= ∑(Probabability of picking 36 and above numbers)
= 1 / 24 + 1/24 + 1/24 + 1/24
= 1 / 6
The probability of repeating this 4 consecutive times is:

There are four people in the Hayden family.each person always eats 3/4 of a cheese pizza. How whole many pizzas should they order? Solve and draw a picture to match this problem
The family consumes 3 whole pizzas in total. They should order 3 whole pizzas to have enough for everyone.
How did we arrive at the value?To find out how many whole pizzas the Hayden family should order, we can calculate the total number of pizzas they need.
Since each person always eats 3/4 of a pizza, the total amount they eat can be calculated as follows:
3/4 + 3/4 + 3/4 + 3/4 = 4 × (3/4) = 3
So, the family consumes 3 whole pizzas in total. Therefore, they should order 3 whole pizzas to have enough for everyone.
