Sarah feeds her fish every 2 days and her snake every 6 days. In 30 days, how many times will Sarah feed her fish and snake on the same day?
Answer:
So if sarah feeds her fish every two days, youd divide each number by 30. So the fish would be fed 15 times and the snake 5 times. Hope you get it correct! Good Luck!
Answer: hello mate!
Sara feeds her fish every 2 days: this means that if we took the 0 in a day that she feed both animals; then the fish gets food on the day 2, on the day 4, on the day 6, etc
And the snake gets food on days 6, 12, 18, etc.
now we want to count the number of days where both animals get food on the same day. Because 6 is a multiple of 2, we can see that every day that the snake is feed, the fish also feed, this is because the minimal common multiple between 2 and 6 is 6.
then we can see that each 6 days Sarah feeds her fish and snake on the same day. Now we need to see the number of times that this event happens in 30 days; we can see this dividing 30 days by 6 days:
30/6 = 5
Then in the span of 30 days, there are 5 times where both animals get food on the same day.
Which function has the greatest rate of change? A. x y 3 3 4 6 5 9 B. y = 4 + 6x C. 12x + 6y = 18 D. A linear function that goes through point 1, negative 1 and point 0, 4
Answer:
B. y = 4 + 6x
Step-by-step explanation:
We know that the rate of change of a straight line is equal to the slope of the line.
Now, the general form of a straight line is y = mx + b, where m is the slope and b is the y-intercept.
Also, the slope of a line joined by [tex]( x_{1},y_{1} )[/tex] and [tex]( x_{2},y_{2} )[/tex] is given by [tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex].
So, using these, we will find the slopes of the lines given in the options.
A. Here, we are given two points (3,3) and (4,6). Then, the slope is given by,
[tex]m_{1}=\frac{6-3}{4-3}[/tex] i.e. [tex]m_{1}=3[/tex].
B. We have the equation of line y = 4 + 6x. On comparing it with the general form, we get that the slope is 6 i.e. [tex]m_{2}=6[/tex].
C. We are given the standard form of a line. First, we convert it into the slope-intercept form ( or the general form ).
i.e. 12x + 6y = 18 → 2x + y = 3 → y = -2x + 3
Now, on comparing this equation with the general form of a line, we get that the slope is -2. i.e. [tex]m_{3}=-2[/tex].
D. Here, we are given a linear function passing through (1,-1) and (0,4). Then the slope is given by,
[tex]m_{1}=\frac{4+1}{0-1}[/tex] i.e. [tex]m_{4}=-5[/tex].
Hence, we obtain that the function y=4+6x has the greatest slope or the greatest rate of change i.e. [tex]m_{2}=6[/tex].

what is the distance between the points -3, 5 and -3,-9?
Answer:
the distance is 14
Step-by-step explanation:
To find the distance between 2 points, we can use the distance formula
d = sqrt( (x2-x1)^2 + (y2-y1) ^2 )
d = sqrt( (-3--3)^2 +(-9-5) ^2 )
= sqrt( (-3+3)^2 + (-14)^ 2)
= sqrt(0^2 +14^2)
= sqrt( 14^2)

You are in charge of decorating your gym for a home coming dance. You bought 6 bags of balloons and 5 bags of sparkling balloons for 19.20$. But you realize this is not enough. Than you buy 8 bags of balloons and 2 bags of sparkling stars for 15.80$. What was the price for each item
.
Answer:
I believe your answer would be 8 dollars and 75 cents. I don't know for sure.
Step-by-step explanation:
Using the provided systems of linear equations method, one bag of regular balloons costs $1.45, and one bag of sparkling balloons costs $2.10.
Explanation:The subject of this question is a typical example of a system of linear equations. Here, we are given two different purchases which give us two equations. We have:
1) 6B + 5S = 19.20 ---> Eq (1) (where B stands for one bag of balloons and S stands for one bag of sparkling balloons)
2) 8B + 2S = 15.80 ---> Eq (2)
Now, to find the prices of B and S (the number of bags of balloons and bags of sparkling balloons, respectively), we can solve this system of equations in two steps: multiplying Eq (2) by 2.5 and then subtracting Eq (1) from the result. This gives:
20B + 5S = 39.5
Then subtract Eq (1) from this new equation, which yields 14B = 20.3. So, one bag of balloons (B) costs $1.45. Substituting B = 1.45 into Eq (1), we get 6(1.45) + 5S = 19.2, which simplifies to 5S = 10.5. Thus, one bag of sparkling balloons (S) costs $2.10. So, the cost per bag of regular balloons is $1.45, and the cost per bag of sparkling balloons is $2.10, and this is how you go about decorating your gym on a budget.

Brad make 3 cups of pancake batter. If he needs 3/4 cup of batter to make 4 pancakes, how many pancakes can Brad make
Answer:
(3/4) cup/4 pancakes = 3 cups/x pancakes
(3/4)x = 12
x = 16
Brad can make 16 pancakes.
Brad can make 16 pancakes with 3 cups of batter, based on the ratio of 3/4 cup batter for every 4 pancakes.
To determine how many pancakes Brad can make with 3 cups of batter, when 4 pancakes require 3/4 cup of batter, we can set up a straightforward ratio and proportion calculation.
First, we divide the total batter amount by the batter requirement for a single group of pancakes: 3 cups / (3/4 cups) = 3 / 0.75 = 4 groups of pancakes.Because each group consists of 4 pancakes, we then multiply the number of groups by the number of pancakes in each group: 4 groups \\times 4 pancakes/group = 16 pancakes.Therefore, Brad can make 16 pancakes with 3 cups of batter.

28 < x < 114
Step-by-step explanation:
x cannot be larger than or even equal to 71 + 43 = 114. So it must be less than 114.But there are limits on the other end as well. 43 +x > 71, otherwise you won't have a triangle. so you have to solve that inequality as well43 + x > 71 Subtract 43 from both sides.43-43 + x > 71 - 43x > 28To put this in the form of the answer you need it looks like this.28 < x < 114What is (3x^4+2x^2-6) subtracted from (4x^4+2x^2-6)
Answer:
The answer is -x^4, Good Luck!
Step-by-step explanation:
(3x^4+2x^2-6) - (4x^4+2x^2-6) = -x^4
To subtract (3x^4+2x^2-6) from (4x^4+2x^2-6), subtract the corresponding terms and keep the same variable raised to the same power. For example, subtracting 3x^4 from 4x^4 gives us x^4. Therefore, the result is x^4.
Explanation:To subtract (3x^4+2x^2-6) from (4x^4+2x^2-6), we need to subtract the corresponding terms. So, subtract the coefficients of like terms. For the terms with variable x raised to a power, subtract the coefficients and keep the same variable raised to the same power. For the constant term, subtract the constants.
For example, subtracting 3x^4 from 4x^4 gives us (4x^4 - 3x^4) = x^4. Subtracting 2x^2 from 2x^2 gives us (2x^2 - 2x^2) = 0. Subtracting 6 from 6 gives us (6 - 6) = 0.
Therefore, the subtraction of (3x^4+2x^2-6) from (4x^4+2x^2-6) results in x^4 + 0 + 0 or simply x^4.

what is the equation in plot slope form of the line that passes through the point (-1, -3) and has a slope of 4
Answer:
y+3 = 4(x+1)
Step-by-step explanation:
Point slope form of a line is
y-y1 = m(x-x1) where m is the slope and (x1,y1) is the point
y--3 = 4 (x--1)
y+3 = 4(x+1)
Answer: plot slope form is y+3= 4(x+1)
or
y = 4x+1
Step-by-step explanation:
Slope point form of equation is given by
y-y1 = m (x-x1)
where m is slope and (x1,y1) is the point
here (point) is (-1,-3) and slope = 4
so equation is
(y - (-3) )= 4 ( x -(-1))
y+3 = 4(x+1)
y+3 = 4x+4
y = 4x +1

A store is having a sale on liquid soap and sponges. The cost of 6 bottles of soap is $9.12. The cost of 4 sponges is $5.00 what is the total cost of buying 2 bottles of liquid soap and 3 sponges
Answer:
$6.79
Step-by-step explanation:
We need to find the cost of a bottle of soap. We divide the cost by the number of bottles
$9.12/6 = $1.52 per bottle
We also need to find the cost for a sponge
$5.00/4 = $1.25 per sponge
We want to find the total cost of 2 bottles of soap and 3 sponges
cost = 2 * 1.52 + 3 * 1.25
= 3.04 + 3.75
= 6.79
Final answer:
The total cost comes to $6.79.
Explanation:
To calculate the total cost of buying 2 bottles of liquid soap and 3 sponges, we need to first find the cost of a single bottle of soap and a single sponge. We can do this by dividing the total cost of multiple items by the number of items to get the price per item.
The cost of 6 bottles of soap is $9.12. To find the cost of 1 bottle of soap, we divide: $9.12 / 6 = $1.52 per bottle.
The cost of 4 sponges is $5.00. To find the cost of 1 sponge, we divide: $5.00 / 4 = $1.25 per sponge.
Now, we can calculate the cost of 2 bottles of soap: 2 x $1.52 = $3.04.
And the cost of 3 sponges: 3 x $1.25 = $3.75.
Finally, we add the two amounts to find the total cost: $3.04 (soap) + $3.75 (sponges) = $6.79
So, the total cost of buying 2 bottles of soap and 3 sponges is $6.79.

A survey about phone service has a margin of error of 5%. Out of 150 people surveyed, 103 said that they were pleased with their service. The phone company has 72,000 customers. What is the range of the number of people that are satisfied?
A. 46,968 to 51,912 customers
B. 46,986 to 51,192 customers
C. 46,698 to 51,291 customers
D. 48,696 to 52,191 customers
Answer:
The range of the number of people that are satisfied is option A. 46,968 to 51,912 customers.
Step-by-step explanation:
Hi, to solve this problem you need to calculate the total number of customers that are pleased with the service, based on the 150 people sample.
so:
(72,000 x 103 )÷150 = 49,440
The next step is to calculate the 5% margin of error of that result.
49,440 x 0.05= 2,472
Finally, to obtain the range you need to add and subtract the margin to the total number of customers that are pleased with the service.
49,440-2,472= 46,968
49,440 + 2,472=51,912
So, the range of the number of people that are satisfied is option A. 46,968 to 51,912 customers.

Donata bought 4 lemons and 4 plums at the local supermarket for a total of $ 21.60. Dan bought 11 lemons and 6 plums at the same store for a total of $40.90 how much does one lemon cost. .... helppppp. How Much does 1 plum cost?
Answer:
Each lemon costs $1.70. Each plum costs $3.70.
Step-by-step explanation:
You have two unknowns and two statements about costs. First, define a variable for each unknown. Then, translate the statements about the costs into two equations. Then, solve the system of equations.
Let L = price of 1 lemon
Let P = price of 1 plum
Donata:
4 lemons and 4 plums for $21.60
4L + 4P = 21.6 Equation 1
Dan:
11 lemons and 6 plums for $40.90
11L + 6P = 40.9 Equation 2
Here is the system of equations.
4L + 4P = 21.6 Equation 1
11L + 6P = 40.9 Equation 2
Divide both sides of Eq. 1 by 4.
L + P = 5.4
Multiply both sides by -6.
-6L - 6P = -32.4
Add the equation above to the Eq. 2.
5L = 8.5
L = 8.5/5
L = 1.7 <------- price of a lemon
L + P = 5.4
1.7 + P = 5.4
P = 3.7 <------ price of a plum
Each lemon costs $1.70. Each plum costs $3.70.

which monomials are divisible by 9
Answer:
Numbers are divisible by 9 if the sum of all the individual digits is evenly divisible by 9
Step-by-step explanation:
5+3+6+4 = 18
18 is divisible by 9 so therefore, those numbers are monomials of the number 9.
Monomials that are divisible by 9 are those whose numeric coefficient is divisible by 9. For example, the monomial 27x or 81y^2 are both divisible by 9 because their numeric coefficients (27 and 81, respectively) are divisible by 9.
Explanation:In mathematics, a monomial is an algebraic expression consisting of one term. Monomials that are divisible by 9 are those whose numeric coefficient is divisible by 9. For example, if you have a monomial like 27x, you can check if it's divisible by 9 by dividing the numeric coefficient (27) by 9. Since 27 divided by 9 is equal to 3, you can conclude that 27x is divisible by 9. Another example would be 81y^2 where the numeric coefficient is 81. Because 81 divided by 9 equal to 9, 81y^2 is also divisible by 9. So any monomial with a numeric coefficient that is a multiple of 9 is divisible by 9.
