What is the ratio of 48 cans for $9.00

Answer: 11cm, 11cm, 16.5cm, 16.5cm

Step-by-step explanation:

To find the length of each side of a rectangle in ratio of 3:2, set up the equation for the perimeter and solve for the sides using algebraic manipulation.

To find the length of each side of the rectangle, we must solve for the sides using the given ratio. Let's assume the ratio is 3x:2x, where x is a common factor. The perimeter of a rectangle is equal to 2 times the length plus 2 times the width. So, we can set up the equation: 2(3x) + 2(2x) = 55 cm. Simplifying the equation, we get 6x + 4x = 55. Combining like terms, 10x = 55, and dividing both sides by 10, we find x = 5. Therefore, the length of each side is 3x = 3(5) = 15 cm, and the width is 2x = 2(5) = 10 cm.

The division is one of the four fundamental arithmetic operations. The number of pages of the album that are completely filled is 13, while the last page of the album has only 1 card.

The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.

Given that Rafel has 118 baseball cards arranged in an album. Also, Each page of the album can hold 9 cards.

Therefore, the number of pages that will be full can be found by dividing the total number of cards available by the total number of cards that each page can have.

In the division, the quotient represents the number of pages which have 9 photos, therefore are full. And the remainder represents the number of photos that will be left on the last page.

The division can be carried out as shown below.

Hence, the number of pages of the album that are completely filled is 13, while the last page of the album has only 1 card.

Final answer:

The inequalities that accurately model the situation where Adam needs fewer than 30 cones, with at least a dozen large ones, are y≥12, x+y≤30, and x≥0. These inequalities represent the constraints on large cones, total cones, and the feasibility of small cones respectively.

Explanation:

The student asks about modeling a situation with inequalities where Adam needs both small and large cones for soccer practice, with fewer than 30 cones total and at least a dozen large ones. The variables x represent the number of small cones and y represent the number of large cones. To accurately model this scenario, the following inequalities are correct:

   y≥12: Adam needs at least a dozen large cones.

   x+y≤30: The total number of cones, both small and large, is less than or equal to 30.

   x≥0: The number of small cones can be zero but not negative, as you can't have a negative number of cones.

Thus, the inequalities that model this situation are y≥12, x+y≤30, and x≥0. These inequalities account for the constraints on the number of large cones needed, the total limit on cones, and the feasibility of the number of small cones respectively.

Final answer:

The item with an original price of $480 is marked down twice, first by 10%, reducing it to $432, and then by another 20%, making the final sale price $345.60.

Explanation:

The original price of the item is $480. The first markdown of 10% reduces the price by $48 (10% of $480), which makes the new price $432. After six months, the item is marked down again by 20%, which is $86.40 (20% of $432). The final sale price of the item after both markdowns is $432 - $86.40 = $345.60.

3y +1 = 16

3y =15

y = 15/3 =5

 y = 5

x = 2(5) +1 = 11

long piece is 11 feet

Answer:

Step-by-step explanation:

This question wants us to write the given line in a slope-intercept form, which is y=mx+b, where m is the slope and b is the y-intercept. We already know the slope, which is 5, so just insert 5 in for m. We get y = 5x = b. We're not done, however, we still need to solve for b. (3,13) equals 5(3)+b=13. This gives us our final result of b=-2. insert this into the equation for b, and the equation becomes y = 5x -2.

The solution of expression is, r = 1

We have to give that,

An expression to solve,

14 = 8 - 6r

Now, Simplify the expression by combining the like terms as,

14 = 8 - 6r

Add 6r on both sides,

14 + 6r = 8 - 6r + 6r

14 + 6r = 8

Subtract 14 on both sides,

6r = 8 - 14

6r = 6

Divide into both sides by 6,

r = 6/6

r = 1

Therefore, The solution is, r = 1

Answer:

x= [tex]\frac{b}{3+9y}[/tex] .

Step-by-step explanation:

Given :  b = 3x + 9xy.

To find :  Solving the equation for x.

Solution : We have given

b = 3x + 9xy.

Taking common 3x from right hand side

b = 3x ( 1 + 3y).

On dividing both sides by 1 + 3y .

[tex]\frac{b}{1+3y}[/tex] = 3x

On dividing both sides by 3

[tex]\frac{b}{(3+9y)}[/tex] = x .

Therefore, x =[tex]\frac{b}{(3+9y)}[/tex] .

x = b/(3 + 9y)

[tex]\boxed{ \ b = 3x + 9xy \ }[/tex]

In the equation, there are three variables, namely b, x, and y. The coefficients of x and xy are 3 and 9, respectively.

We need solving for x from the equation.

Let us reposition it by swapping sides. The aim is to prepare x as the subject on the left-hand side.

[tex]\boxed{ \ 3x + 9xy = b \ }[/tex]

On the left-hand side, 3x is pulled out of the brackets because it is the GCF (The Greatest Common Factor) of 3x and 9xy.

[tex]\boxed{ \ 3x(1 + 3y) = b \ }[/tex]

Both sides divided by 3(1 + 3y).

[tex]\boxed{ \ x = \frac{b}{3(1 + 3y)} \ }[/tex]

Hence, the final result is

[tex]\boxed{\boxed{ \ x = \frac{b}{3 + 9y} \ }}[/tex]

That's all the steps to get x as a subject.

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

Summation = addition of two or more numbers or variable

For example = 2 + 8 + 9

Subtraction = Minus of any two or more numbers with each other called subtraction.

For example = 4 - 8

Division = divide any two numbers or variable called division.

For example 4/8

Multiplication = to multiply any two or more numbers or variables called multiplication.

For example 5 × 7.
