Step-by-step explanation:3 x 1/3 =
First we should understand that 3 in fraction form is 3/1.
(3 divided by 1 is three)
So we can rewrite this as;
3/1 x 1/3 =
Now just multiply across
3/1 x 1/3 = 3/3 = 1
Repeating this same logic we'll come across the following answers
10 x 1/10 = 10/10 = 1
19 x 1/19 = 19/19 = 1

Answer:
Step-by-step explanation:
We can use the method of undetermined coefficients to solve this differential equation. First, we will need to find the solution to the homogeneous equation and the particular solution to the non-homogeneous equation.
For the homogeneous equation, we will use the form y"+ky=0, where k is a constant. We can find the solutions to this equation by letting y=e^mx,
y"=m^2e^mx -> (m^2)e^mx+k*e^mx=0, therefore (m^2+k)e^mx=0
(m^2+k) should equal 0 for the equation to have a non-trivial solution. Therefore, m=±i√(k), and the general solution to the homogenous equation is y=A*e^i√(k)x+Be^-i√(k)*x.
Now, we need to find the particular solution to the non-homogeneous equation. We can use the method of undetermined coefficients to find the particular solution. We will let yp=a0+a1x+a2x^2+.... As the derivative of a sum of functions is the sum of the derivatives, we get
yp″=a1+2a2x....yp‴=2a2+3a3x+....
Substituting the general solution into the non-homogeneous equation, we get
a0+a1x+a2x^2+...+2a2x+3a3x^2+...=Y(4)
So, the coefficient of each term in the expansion of the left hand side should equal the coefficient of each term in the expansion of the right hand side. Since there is only one term on the right hand side, we get the recurrence relation:
a(n+1)=Y(n-2)/n^2
From this relation, we can find all the coefficients in the expansion for the particular solution. Using this particular solution, we can find the total solution to the differential equation as the sum of the homogeneous solution and the particular solution.

why is 4320 divisible by 3, 9, and 10
Answers
Answer:
One integer A is divisible by another integer B,
if after dividing them, A ÷ B, the remainder is zero.
4,320 is divisible by 10, if there is an integer 'n' such that 4,320 = 'n' × 10.
Notice that dividing our numbers leaves no remainder:
4,320 ÷ 10 = 432 + 0;
So, 4,320 = 432 × 10;
=> 4,320 is divisible by 10.
10 is called a divisor (a factor) of 4,320.
10 | 4,320
The shorthand notation A | B means A divides B.
4,320 is a multiple of 10.
Note that this is also the first step of the Euclidean Algorithm, where the division of the numbers stops when a remainder equal to zero is reported.
4,320 is divisible by 10:

In a classroom, 100 plastic fish are in a tub. The tub is hidden from the student view. Some fish are green, and the rest are yellow. The students know that there are 100 fish, but they don’t know how many of each color there are. The students go fishing, each time, picking a random fish from the tub, recording its color, and throwing the fish back in the tub. At the end of the day, 65 fish have been chosen, 12, green and 53 yellow. What is the best estimate you can give for the number of green fish in the number of yellow fish in the tub? Describe how to calculate this best estimate, and explain why your method of calculation makes sense in a way that a seventh grader my understand. Is your best estimate necessarily accurate? Why or why not?
Answers
The best estimate for the number of fish is that there are 82 yellow fish and 18 green fish, which you can calculate using the rule of three. This estimate is expected to be accurate.
What is the estimated number of fish of each color?This can be calculated using a rule of three as follows. Let's start with the yellow fish:
53 = 65
x = 100
53 x 100 / 65 = 82 yellow fish
Green fish:
12 = 65
x = 100
12 x 100 / 65= 18 green fish
Is this estimate accurate?This estimate is expected to be accurate; however, there might be small differences in real life such as 80 yellow fish and 20 green fish.

Answers
Answer: $43.50
Step-by-step explanation:
In the problem we are given the cost of two scarves, which is $29. However, we are not informed of the cost of each individual scarf which is the first step we must take in finding the cost of three. The easiest way to do this is to set up an equation.
Let the variable x=the cost of one scarf
2x=29
Using previous knowledge of problem solving and inverse operations, we know that in order to get the x by itself, we must divide by two to cancel out the multiplication by two.
2x=29
2 2
x = 14.5
Now that we have the cost of one scarf, we can plug in that amount to get the cost of three
3(14.5)= 43.5

Step-by-step explanation:
The percentage refers to the per hundred or hundredths and is ended with the symbol %. By dividing two amounts, ratios and percentages are both used to compare the two amounts.
The formula for finding the percentage is to divide the value by the total value and then multiply the value by 100.percentage = ( given value / total value ) x 100so,

12 cows - 48 legs
4 ducks- 8 legs
- there are many different numbers you can do but if you want to change the numbers and have more ducks then: for every one cow you take away two more ducks.
Step-by-step explanation:
22 total animals
56 total legs
ducks have 2 legs
cows have 4 legs
12 times 4 = 48 ( 12 cows with 4 legs each cow = 48 legs)
4 times 2 = 8 ( 4 ducks with 2 legs each duck = 8 legs)
Creating a system of equation using the scenario described, the number of cows and ducks owned are 6 and 16 respectively.
Number of legs per cow = 4 Number of legs per duck = 2 Number of ducks = dNumber of cows = cThe equation goes thus :
c + d = 22 - - - (1)
4c + 2d = 56 - - - (2)
From (1)
c = 22 - d - - - - (3)
Substitute (3) into (2)
4(22 - d) + 2d = 56
88 - 4d + 2d = 56
88 - 2d = 56
-2d = 56 - 88
-2d = - 32
d = 16
From (3)
c = 22 - 16
c = 6
Hence, the number of cows and ducks owned are 6 and 16 respectively.

Given function in the question → y = alog(x + c) + d
Rules for the translation of a function,
If a function y = f(x) is shifted 'h' units upwards on y-axis, rule for the translation will be → y = f(x) + hIf the function y = f(x) is shifted 'h' units downwards, rule for the translation → y = f(x) - hHence, in the given function y = alog(x + c) + d, positive value of 'd' will define the shifting of the parent function upwards.
And for the negative value of 'd' will define the shift of the function downwards.

Initial amount: 934 g
After 80 years: 147 g
Step-by-step explanation:
\( A(t) = 934 (\dfrac{1}{2})^\frac{t}{30} \)
The initial amount occurs at t = 0.
\( A(0) = 934 (\dfrac{1}{2})^\frac{0}{30} \)
\( A(0) = 934 (\dfrac{1}{2})^0 \)
\( A(0) = 934 \times 1 \)
\( A(0) = 934 \)
After 80 years, t = 80.
\( A(80) = 934 (\dfrac{1}{2})^\frac{80}{30} \)
\( A(80) = 934 (\dfrac{1}{2})^\frac{8}{3} \)
\( A(80) = 934 (0.15749) \)
\( A(80) = 147 \)
