Which of the following is an example of a rational number that is not an integer? a. -3 b. 1 c. 1/3 d. 3
Answer:
the answer is C.1/3
Step-by-step explanation:
Here is why in mathematics, a rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Since q may be equal to 1, every integer is a rational number. Hope this helps. :)
Answer:
1/3
Step-by-step explanation:
1/3 is the only rational number that isnt an interger.
3(y-2x) = 9
x - 4 = 0
PLSSS HELPPP
Answer:
(x, y) = (4, 11).
Step-by-step explanation:
We have two equations:
3(y-2x) = 9
x - 4 = 0
From equation 2, we have x = 4. We can substitute this value into equation 1 and solve for y:
3(y-2x) = 9
3(y-2(4)) = 9 (substitute x = 4)
3(y-8) = 9
3y - 24 = 9
3y = 33
y = 11
Therefore, the solution to the system of equations is (x, y) = (4, 11).

In 56 years, Kevin will be 9 times as old as he is now
How old is Kevin now?
Answer:
correct answer is 7 years
Step-by-step explanation:
A+56=9(A)
56+9A
A=7
he will be 7 years old he is pretty old
Answer:
Kevin is 7 years old right now.
Step-by-step explanation:
Let x be Kevin's age right now, that's what we're trying to find.
In 56 years, he'll be 9 times older than he is now, so we can say:
x + 56 = 9x
Now we can get the x values on the right side of the equation so that:
56 = 8x
Now solve for x and you have his current age which is 7.

CHOICE A ⇒ the test score s in ken ’ s class are more spread out compared to those in judy ' s class .
CHOICE B ⇒ the median score is equal to the mean score in both classes .
CHOICE C ⇒ the mean score is greater in judy ’ s class compared to ken ’ s class .
CHOICE D ⇒ the median score in ken ’ s class is greater than the median score in judy ’ s class .
the meadian score is greater in Judy’s class compared to Ken’s class.
Kens class has a mean score of 83, and Judy's class has a mean score of 86.43(rounded) so, judging by the mean, Judy's class is smarter. If we take a look at the median, (Ken: 84, and Judy: 87) then Judy's class is smarter. So, overall Judy's class is smarter than Ken's class.
Explain the cosine rule and sine rule while also saying how to use it and provide examples (keep it in simple terms)
Answer:
Sure, I'll explain the cosine rule and sine rule in simple terms:
The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.
Here's an example of how to use the cosine
Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.
Using the cosine rule:
a^2 = b^2 + c^2 - 2bc * cosA
where A is the angle opposite side a, we can plug in our values and solve for a:
a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)
a^2 = 64 + 36 - 96 * 0.707
a^2 = 10.56
a = sqrt(10.56)
a = 3.25 (rounded to two decimal places)
Therefore, the length of side a is approximately 3.25 units.

Tina chose A as the correct answer. How did she get that answer?
Answer: Tina is correct
Step-by-step explanation:
this is because in one foot there are 12 inches and there are 5 feet so 5 X 12= 60 and aaron is 63inches so he is tall enough and 63-60=3 inches so he is 3 inches taller than 5 feet.
Pls give me brainliest!!!
Answer:
Yes. He is 3 inches taller than 5 feet
Step-by-step explanation:
We know that 1 ft is 12 inches
5 ft * 12 inches/ 1 ft = 60 inches
You must be 60 inches to ride and Aaron is 63 inches
He is 3 inches taller
63 - 60 = 3 inches

Answer:
x÷3+5=6
Step-by-step explanation:
1. (x/3)+5=6
2. x/3=1/3x
3. subtract 5 from both sides and get 1/3x=1
4. multiply both sides by 3 because if u want to find what x equals u need to multiply it so its not 1/3x

Answer: Range and mean = 8 of both
variance of Set X= 4.7
variance of Set Y= 4.6
Step-by-step explanation:
Two sets of data, set X and set Y are given
a.) Range is the difference of the highest value and the lowest value,
Therefore, Range of set X = 12-4=8
Range of set Y = 12-4=8
Now, Mean of a given data set is the average of all the terms present in the given data set
Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8
Mean of set Y= (4+5+7+32+20+12)/10= 8
Therefore, both the data sets has same range and mean.
b.) Standard deviation tells about the variability of the date and is given by,
S.D= σ = √∑ ( X − μ )^2/n
S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7
S.D of set Y= √(16+9+1+0+4+16)/10= √4.6
Variance is the square of S.D, that is, σ^2
Therefore, variance of set X=4.6
variance of set Y= 4.7
c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

What is the probability of rolling a number less than or equal to 5 on a fair number
cube? Justify your answer.
Answer:
Step-by-step explanation:
The probability of rolling a number less than or equal to 5 on a fair number cube (also known as a fair six-sided die) is 5/6.
Justification: A fair number cube has six sides, numbered 1 through 6. Out of these six numbers, there are five numbers (1, 2, 3, 4, and 5) that are less than or equal to 5. Therefore, the favorable outcomes are 5, and the total possible outcomes are 6. Thus, the probability is 5/6.

Triangle JKL has vertices at J(−1, −5), K(−2, −2), and L(2, −4). Determine the translation direction and the number of units of the image of triangle JKL if vertex J′ is at (−1, −8).
3 units down
3 units up
7 units to the right
7 units to the left
Answer:
3 units down
Step-by-step explanation:
J(-1, -5) → J'(-1, -8)
The x coordinate of the vertex J is -1 and does not change in J' (it is still -1)
The y coordinate of J is -5, and for J' is -8. This means the translation direction of 3 units down. (-8- -5 = -3)
At the store you want to buy a bunch of 3d printed Christmas gifts for your family. Each large tree costs $4.50 , and each small tree costs $2.25, If you buy 4 large trees, and can spend a total of $50. Write and solve an inequality for number of small trees (s) you can buy
We know that each large tree costs $4.50, and each small tree costs $2.25. If you buy 4 large trees, that means you will spend 4 * $4.50 = $<<4*4.5=18>>18 on large trees.
If you can spend a total of $50, then you have $50 - $18 = $<<50-18=32>>32 to spend on small trees.
The total cost of the small trees will be s * $2.25, where s is the number of small trees you buy.
To find the maximum number of small trees you can buy, we can set this expression equal to $32 and solve for s:
s * $2.25 = $32
s = $32 / $2.25
s = 14.22
Since you can't buy a fraction of a tree, the maximum number of small trees you can buy is 14.
Answer:
If each large tree costs 4.50 and you need to buy 4, then 4 x 4.50 = $18.00 leaving you with $32.00. With these 32 dollars left, you can now buy 14 small trees, still being left with a remainder of 0.50$.

Which expression has a value of 35 when p = 7?
StartFraction 49 Over p EndFraction
5p
45 minus p
25 + p
Answer:
When p = 7, the expressions have the following values:
- StartFraction 49 Over p EndFraction = StartFraction 49 Over 7 EndFraction = 7
- 5p = 5(7) = 35
- 45 - p = 45 - 7 = 38
- 25 + p = 25 + 7 = 32
Therefore, the expression that has a value of 35 when p = 7 is 5p.
Answer:
B) 5p
Step-by-step explanation:
We have to solve each equation for when p=7
Option A)
\(\frac{49}{p}\\ =\frac{49}{7}\\ =7\) This is incorrect.
Option B)
\(5p\\=5(7)\\=35\) This is correct.
Option C)
\(45-p\\=45-7\\=38\) This is incorrect.
Option D)
\(25+p\\=25+7\\=32\) This is incorrect.
Option B is correct, hope this helps! :)
