After 60 minutes both buckets dump water at the same time again.
What is LCM?The least common multiple that is divisible by both a and b is the smallest positive integer, lowest common multiple, or smallest common multiple of two numbers a and b, generally indicated by LCM.
Given:
One bucket dumps water every 12 minutes. , while the other bucket dumps water every 10 minutes.
So, to find the When will both buckets dump water at the same time again we have to find the LCM
10 = 1 × 2 × 5
12 = 1 × 2 × 2 × 3
LCM = 1 × 2 × 2 × 3 × 5 = 60
Hence, After 60 minutes both buckets dump water at the same time again.

11. REINFORCE In the circle below, the distance CN equals 3x - 10 and the distance CK
equals x2 - 20. Find the distance CP.
Answer:
5 units
Step-by-step explanation:
Here, we want to find the distance CP
the distance from the center of the circle to the circumference is referred to as radius.
Hence CP is the radius of the circle
Also CN is another radius and also CK is another radius
Thus, mathematically; CN = CK
This means that;
x^2 -20 = 3x -10
x^2 -20 -3x + 10 = 0
x^2 -3x -10 = 0
x^2 -5x + 2x -10 = 0
x(x-5) + 2(x-5) = 0
(x-5)(x+2) = 0
x = 5 or -2
To get CP , we can substitute for x in any of the given expressions
Let’s use 3x-10
Using x = 5
3(5) -10 = 15-10 = 5
Using x = -2
3(-2) -10 = -6-10 = -16
But since length cannot be negative , 5 units is our answer

Step-by-step explanation:
Suppose you launch a model rocket with an upward starting velocity of v ft/s. You can use the equation to find the rocket's altitude, h represents height in feet, t seconds after launch and represents initial height. Suppose the upward starting velocity is 315 ft/s and the initial height is 3 ft. When will the rocket hit the ground?
Answer:
The rocket will hit the ground at 64.2 seconds.
Step-by-step explanation:
The time at which the rocket will hit the ground can be calculated using the following equation:
[tex] Y_{f} = Y_{0} + V_{0}y*t - \frac{1}{2}gt^{2} [/tex]
Where:
[tex]Y_{f}[/tex]: is the final height = 0
[tex]Y_{0}[/tex]: is the initial height = 3 ft
[tex]V_{0}[/tex]: is the initial speed = 315 ft/s
t: is the time =?
g: is the gravity = 9.81 m/s²
[tex] 3 + 315*t - \frac{1}{2}9.81*t^{2} = 0 [/tex]
Solving the above quadratic equation for t, we have the following values:
t₁ = -0.0095 s
t₂ = 64.2 s
Taking the positive value, we have that the rocket will hit the ground at 64.2 seconds.

Answer:
The number of apples in the 12th bag is 9
Step-by-step explanation:
The Mean Value of a Data Set
The mean or average of a data set is found by adding all numbers and then dividing by the number of values in the set. Written as a formula:
[tex]\displaystyle \bar x=\frac{\sum{x_i}}{n}[/tex]
Where xi is the value of each data and n is the total number of values.
We are given the value of n=12 and the mean number of apples in each bag (8), thus:
[tex]\displaystyle 8=\frac{\sum{x_i}}{12}[/tex]
Multiply by 12
[tex]\sum{x_i}=96[/tex]
This means the sum of all the values is 96. If we add the existing values from the table, considering their frequency, we have:
[tex]6*1+7*4+8*2+9*3+10*1=87[/tex]
Note the sum should be 96, so the 12th bag must have 96-87=9 apples
The number of apples in the 12th bag is 9

Find the perimeter??? Anyone?!!!!
Answer:
a.) 2(2x)+2(4x-3)
b.)2(2x)+2(4x-3)=42
Step-by-step explanation:
b.)2(2x)+2(4x-3)=42
distribute
4x+8x-3=42
add the like terms
12x-3=42
move the -3 by adding to both sides
12x=45
divide both sides by 12
12x/12=45/12
x=3.75
and to make sure it's right, plug x into the equation.
2(2(3.75))+2(4(3.75)-3)=42
now multiply/add/subtract everything.
2x2x3.75=15 (This was the 1st set of parenthesis)
2x4x3.75-3=27 (This was the 2nd set of parenthesis)
15+27=42
42=42

Answer:
your 'x' is negative and your 'y' is positive
In the case when the point (x, y) is in Quadrant II so here considered that
your 'x' is negative and your 'y' is positive.
What is Quadrant II?The second quadrant should be occur in the upper left-hand corner of the plane. X contains the negative values in this quadrant and y should have the positive values.
So based on the above information, we can say that your 'x' is negative and your 'y' is positive.

A golfer earned the following scores over several rounds of golf: −3, 2, 0, −1, 2, −4. Jamar says these numbers can all be described as integers, while Sophia says they are whole numbers. Which student is correct? Explain how you know.
Answer: Jamar is correct
Step-by-step explanation:
Integer is a number that is a whole number and can either be positive or negative but it can't be a fraction or decimal. e.g 4, -2, 6, -23 etc.
A whole numbers are zero and other natural numbers such as 1, 4, 23. Negative numbers are not part of whole numbers.
From the statement made in the question, Sophia is wrong while Jamar is correct. The numbers aren't all whole numbers because some are negative.
Imagine that you randomly select a sample of 30 newborn infants and find that their mean weight is 8.1 pounds. The population mean of newborn infants is known to be 7.4 pounds with a standard deviation of 1.1 pounds. Would a sample mean as large as 8.1 be more or less likely if N = 10? Why?
Answer: more likely
Step-by-step explanation:
Given that :
Population Mean = 7.4
Population standard deviation = 1.1
Sample mean with a sample size of 30 = 8.1
A sample mean of 8.1 will be more likely with a sample size (N) of 10 because, the sampling distribution gets wider with decreasing sample size and narrower with larger sample sizes, hence, sample mean seems to conform with the population mean when the sample size are very large according to the central limit theorem. Hence, since a sample size of 30 results in a sample mean of 8.1, reducing the sample size will either give a similar sample mean or a sample mean further away from the population mean.

-3[1+2(4+5)]
PLease answer ASAP!!!
Answer:
-57
Step-by-step explanation:
Use BOMASB- brackets
O- of
M- multiplication
A- addition
S - subtraction
-3[1+2(4+5)]
first solve what is in the brackets
(4+5) = 9
place 9 in the brackets
-3[1+2(9)]
now multiply the 2 and 9
2*9 = 18
-3[1+18)]
1+ 18 = 19
now multiply the (-3) with 19
= -57
Answer:
-57
Step-by-step explanation:
To solve this problem, you need to use the acronym PEMDAS.
P = parenthesis (if there is any in the expression) or brackets
E = exponents (if there is any in the expression)
D/M = Divide or Multiply or both
A/S = Add or Subtract or both
In the problem, you need to simplify the parentheses ( ) inside the brackets first. For example: -3 [1 + 2(4 + 5)]. That will equal to -3 [1 + 2(9)]. Next, you can solve the brackets now. Since there is both a addition and multiplication problem inside these brackets, you must do the multiplying first. For example,
-3 [1 + 2(9)]. That equals to -3 [ 1 + 18}. Next, do the addition inside of the brackets and then multiply that answer to -3. For example, -3 [1 + 18}. That equals to -3 [19]. Do the multiplication by a calculator or by hand. if you are doing by hand, ignore the signs of the numbers until the very end.
If doing by hand, first you need to multiply 9 by the 3 to get 27. Keep the 7 and borrow a 2 on top of the ones places which is 1. Multiply the 1 by the 3 which gets 3 and add 2 to the 3 to get 5. You got the 2 from multiplying 9 by 3 which is 27. Since the 3 in this problem is negative, that will leave your answer with a negative number. Since a negative times a postive will always be negative. If the number of negatives is odd in the problem, then it will a negative answer. If the number of negatives is even, the answer will be positive. Same thing applies to division. You get -57 as your answer.

A rectangle is four times as long as it is wide. The perimeter is 40 cm. Find the length of each side.
Answer:
W=4 l=16
Step-by-step explanation:
Let w = width
Let l = length
Since the length is 4 times the width, l=4w
Perimeter of rectangle = 2l + 2w
= 2(4w)+2w
=10w
The perimeter of the rectangle =40, so
40=10w and w=4
Plug w into the length equation : l=4w=4(4)=16
