Ryan has a collection of 216 baseball cards. He lets his brother have 1/3 Ryan has a collection of 216 baseball cards. He lets his brother have 1/3 of his collection and takes 27 cards to school to give his friends. How many baseball cards remain in Ryan's collection? 127 cards 90 cards 117 cards 126
Answers
Answer:
117 cards
Step-by-step explanation:
Total number of cards in the collection of Ryan = 216
Number of cards given to his brother = ⅓ of 216 = ⅓ × 216 = 216/3 = 72
Number of cards given to his friend at school = 27
Number of baseball cards that Ryan has remaining = 216 - (72 + 27)
= 216 - 99
Number of cards remaining = 117 cards

Answers
Answer:
4
Step-by-step explanation:
You would use a^2+b^2=c^2
a^2+3^2=5^2
a^2+9=25 subtract nine from both sides
a^2=16
find the square root of 16 which is 4
so the other side of the triangle is 4
Answer:
4 cm
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
let x be the length of the 3 rd side, then
x² + 3² = 5²
x² + 9 = 25 ( subtract 9 from both sides )
x² = 16 ( take the square root of both sides )
x = [tex]\sqrt{16}[/tex] = 4
The third side is 4 cm

At a large university, the probability that a student takes calculus and statistics in the same semester is 0.02. The probability that a student takes statistics is 0.18, while the probability of taking calculus is 0.10. Find the probability that a student is taking calculus given that he or she is taking statistics.
Answers
Answer:
The probability that a student is taking calculus given that he or she is taking statistics is = 0.26
Step-by-step explanation:
the probability that a student is taking calculus given that he or she is taking statistics.
Let C = Calculus
S = Statistics
We solve this above Question nursing the formula;
P ( C ∪ S) = P(C) + P ( S ) - P ( C ∩ S)
From the question,
P(C) = 0.10
P( S ) = 0.18
P ( C ∩ S) = 0.02
P ( C ∪ S) = ???
P ( C ∪ S) = 0.10 + 0.18 - 0.02
= 0.28 - 0.02
= 0.26

No, he is incorrect. Using a number line to model thirds means that each space that is 1/3 should be divided into 3 parts, not 2 parts. 6 parts divided into 3 groups gives 2 parts out of 9 parts total, so the answer is 2/9.

Find m angle MOP if m angle MON =4x+9 and m angle MOP =3x-3
Answers
Answer:
33
Step-by-step explanation:
Measure of ∠MOP is equals to 71.7°.
What are supplementary angles?
" Supplementary angles are those angles whose sum is equals to 180°."
According to the question,
∠MOP = 3x - 3
∠MON = 4x + 9
As ∠MOP and ∠MON has common arm OM.
Therefore, ∠MOP and ∠MON are supplementary angles.
As per definition of supplementary angles we have
∠MON + ∠MOP = 180°
Substitute the value of ∠MOP and ∠MON we get,
4x + 9 + 3x - 3= 180°
⇒7x - 6 = 180°
⇒7x = 174
⇒ x = 24.9 (round off)
Substitute the value of x in measure of ∠MOP we get,
∠MOP = 3(24.9) -3
= 71.7°
Hence, measure of ∠MOP is equals to 71.7°.

Answers
Answer:
2/6 = A and 5/6 =B
Step-by-step explanation:
the line is split into 6 segments. so this means each little line is 1/6. if each line is 1/6, 2 lines, which is A, is 2/6 and 5 lines is 5/6. just multiply 1/6 * th number of lines from the start of the line to the letter
The fraction for point A on the number line will be 2/6 and the fraction for point B will be 5/6 respectively.
What is a fraction?Parts of an entire or group of items are represented by fractions. Each fraction has two components. The numerator refers to the number at the top of the line. It indicates how many equal portions of the total or collection are taken. The denominator refers to the figure below the line. It displays how many identical things there are in a collection or how many total equal elements there are to a whole.

Crafts books: 7

Step-by-step explanation:
Let x be the crafts book
Let y be the cookbooks
Solve for x:
Plug x and y in: x + y = 20Re-write: y = x + 6Plug in x + 6 instead of y: x + x + 6 = 20Combine like terms: 2x + 6 = 20Subtract 6 from each side, so it now looks like this: 2x = 14Divide each side by 2 to cancel out the 2 next to x. It should now look like this: x = 7Solve for y:
Re-use an equation from above: y = x + 6Plug in the value of x: y = 7 + 67 + 6 = 13So, y = 13I hope this helps!
how far would a 4.0 cm tall object be located from a reflecting surface with a focal lenght that is equal to 5 cm if it is to create an image seen 15 cm behind the mirror. Determine the image size
Answers
Answer:
HERE IS YOUR ANSWER
Step-by-step explanation:
Use the mirror equation:
1/di + 1/do = 1/f
where di = -10 cm and f = +15 cm. (Note that di is negative if the image is virtual.)
Substitute and solve for do.
1/do + 1/(-10 cm) = 1/(15 cm)
1/do = 1/(15 cm) - 1/(-10 cm) = 5/(30 cm)
do = 6 cm

Answers
Answer:
The valid range is 697 to 702
Step-by-step explanation:
The question is incomplete; However, the requirement would likely be to determine the valid range which users can guess
Given
[tex]Keys = 697[/tex]
[tex]Difference = 5[/tex]
First, we need to determine the minimum
[tex]Minimum = Keys - Difference[/tex]
[tex]Minimum = 697 - 5[/tex]
[tex]Minimum = 697[/tex]
Next, we determine the maximum
[tex]Maximum = 697 + 5[/tex]
[tex]Maximum = 702[/tex]
Hence:
The valid range is 697 to 702
