Final answer:

To solve both 3/8 x 4 and 3/6 x 4, we multiply the numerator by 4 and simplify the resulting fraction if necessary, resulting in 1.5 for the first expression and 2 for the second.

Explanation:

To solve the problem 3/8 x 4 and 3/6 x 4, we need to perform multiplication of a fraction by a whole number. For the first part, we multiply the numerator (3) by the whole number (4) and keep the denominator (8) to get 12/8, which simplifies to 1 1/2 or 1.5. For the second part, we simplify the fraction 3/6 to 1/2 since both the numerator and denominator can be divided by 3. Then, again, we multiply the numerator (1) by the whole number (4) and keep the denominator (2), resulting in 4/2, which simplifies to 2.

The area of the rectangle will be 12b⁶ + 6b³ – 18b².

Let H be the height and W be the width of the rectangle. The area of the rectangle is the product of height and width.

Then the area of the rectangle will be

Area of the rectangle = H × W square units

A rectangle has a height of 3b² and a width of 4b⁴ + 2b – 6.

Then the area of the rectangle will be

Substitute H = 3b² and W = 4b⁴ + 2b – 6. Then the area of the rectangle will be

Area of the rectangle = 3b² x (4b⁴ + 2b – 6)

Simplify the equation, we have

Area of the rectangle = 3b² · 4b⁴ + 3b² · 2b – 3b² · 6

Area of the rectangle = 12b⁶ + 6b³ – 18b²

Thus, the area of the rectangle will be 12b⁶ + 6b³ – 18b².

Answer:

x = 30, y = 18

Step-by-step explanation:

Given the 2 equations

x - 2y = - 6 → (1)

x - y = 12 → (2)

Subtracting (2) from (1) term by term will eliminate the term in x

||(x - x) + (- 2y - (- y)) = (- 6 - 12), that is

- y = - 18 ( multiply both sides by - 1 )

y = 18

Substitute y = 18 into either of the 2 equations for value of x

Substituting in (2)

x - 18 = 12 ( add 18 to both sides )

x = 30

Answer: (30,18)

x - 2y = -6

x - y = 12

x - y = 12

- y = 12 - x

y = -12 + x

x - 2y = -6

x = -6 + 2*y

y = -12 + (-6+ 2*y)

y = -12 - 6 + 2*y

y - 2*y = -18

-y = -18

y = 18

y = -12 + x

18 = -12 + x

-x = -12 - 18

x = 12 + 18

x = 30

Answer:

The number of minutes of call for long distance is 500 minutes .

Step-by-step explanation:

Given as :

The two different long distance telephones plans are plan A and Plan B

Plan A

monthly fee = $40.00

The charge per minute = $0.05

Plan B

monthly fee = $15.00

The charge per minute = $0.10

now, for both plans

Let The number of minutes of call for long distance = n minutes

So, According to question

∵ The both plans to be same

Monthly fee for plan A + The charge per minute ×  number of minutes of call for long distance for A = Monthly fee for plan B + The charge per minute ×  number of minutes of call for long distance calls for B

i.e $40.00 + $0.05 × n =  $15.00 + $0.10 × n

Or, $40.00 - $15.00 =  $0.10 × n -  $0.05 × n

Or, $25 =  $0.05 × n

∴ n = [tex]\dfrac{25}{0.05}[/tex]

I.e n = 500 minutes

So, The number of calls minutes = n = 500 minutes

Hence, The number of minutes of call for long distance is 500 minutes . Answer

The area of the rectangle is 0.75 of the square of the length. When the length is doubled, the width is 37.5 % of the length.

The area of a rectangle is calculated by multiplying its length and width. In this case, the width is 75% of the length. So if we denote the length as 'L', then the width would be 0.75 * L. Therefore, area would be L * 0.75L = 0.75 * L^2.

Now, if the length of the rectangle is doubled, the width remains the same, so it becomes 0.75 * 2L. So the width becomes a smaller fraction of the length. We can work out this out as follows: (0.75L / 2L) * 100 = 37.5%.

So, when the length of the rectangle is doubled, the width is 37.5 % of the length.

1. The area of the rectangle is 0.75 times the square of the length.

2. The width is now 75% of the length.

Part 1:

What is the area of the rectangle?

If the width of the rectangle is 75% of its length, then we can express the width as 0.75 * length.

The area of a rectangle is calculated by multiplying the length and width, so the area of the rectangle in this case is:

Area = length * width = length * 0.75 * length = 0.75 * length^2

Therefore, the area of the rectangle is 0.75 times the square of the length.

Part 2:

The length of the rectangle is doubled. What percent of the length is the width now? Explain your reasoning.

If the length of the rectangle is doubled, then the width is now half of 75% of the new length.

To calculate this, we can use the following steps:

Calculate the new length of the rectangle: old_length * 2 = new_length

Calculate 75% of the new length: 0.75 * new_length

Divide the width by the new length to get the percentage: width / new_length

For example, if the old length of the rectangle was 10 cm, then the new length would be 20 cm. 75% of 20 cm is 15 cm. Therefore, the width is now 75% of the length.

Answer: The width is now 75% of the length.

x=-7

Step-by-step explanation:

The value of x if,  Lines 1 and 2 are parallel, LINE 1: (-2,5) and (0,0) LINE 2: (x,12) and (-3,2) is -7.

An object having an endless length and no width, depth, or curvature is called a line. Since lines can exist in two, three, or higher-dimensional environments, they are one-dimensional things.

Given:

Line 1 and line 2 are parallel,

The coordinates of lines are given as,

LINE 1: (-2, 5) and (0, 0) LINE 2: (x, 12) and (-3, 2)

As we know that the slope of the parallel lines is equal,

Calculate the slope of Line 1 as shown below,

Slope = 0 - 5 / 0 - (-2)

Slope = -5 / 2

Thus, for the second line,

The slope of Line 2 = (2 - 12) / (-3 - x)

-5 / 2 = -10 / -3 - x

-5(-3 - x) = -20

15 + 5x = -20

5x = -20 - 15

x = -35 / 5

x = -7

Step-by-step explanation:

Cost of 1 cellular bill = (number of text msgs per day) x (cost per text msg) x (number of days in billing period)

in this case, it is given that :

cost per text msg = $0.89

number of texts per day = 22 or 23

billing cycle = 6 weeks = 6 x 7 = 42 days

hence,

Cost of 1 cellular bill = (22 or 23) x $0.89 x 42 days

if she sends 22 messages,

Cost of 1 cellular bill = (22) x $0.89 x 42 days= $822.36

if she sends 23 messages,

Cost of 1 cellular bill = (2) x $0.89 x 42 days= $859.74

Answer:

No! {-2, 1} is not a solution set to the given equation.

Step-by-step explanation:

The statement  X squared take away 2X Takeaway three equals X take away one can be written in mathematical terms as follows:

X² - 2X - 3 = X - 1

⇒ X² - 2X - 3 - X + 1 =0

⇒ X² - 3X - 2 = 0

Now, substitute x= -2 and see if the equation is satisfied.

⇒ (-2)² -3(-2) - 2 = 4 + 6 - 2

= 8 ≠ 0

So, -2 is not a solution to the equation.

Now, check for x = 1.

⇒ (1)² - 3(1) - 2 = 1 - 3 - 2

= -4 ≠ 0

⇒ x = 1 is not a solution as well.

Answer:

The price per pound of apples is greater than $1.

Step-by-step explanation:

Please consider the complete question:

Three coworkers decided to buy fruit to share at lunch time. Antonii spent $1.47 on bananas.Laura spent $2.88 on apples. Suzanne spent $2.85 on oranges.   If Laura bought 2.1 pounds of apples, is the price per pound of apples greater than or less than $1 ? how can you tell?

To find the price of apples per pound, we need to divide total amount paid by Laura ($2.88) with total pounds of apples (2.1 pounds) bought.

[tex]\text{Price of apples per pound}=\frac{\$2.88}{2.1}[/tex]

[tex]\text{Price of apples per pound}=\$1.37142857[/tex]

Since the price of apples per pound is $1.37, therefore, the price per pound of apples is greater than $1.

We can simply tell that the price per pound of apples is greater than $1 because 2.88 is greater than 2.1. So when we will divide 2.88 by 2.1, then we will get a number greater than 1.

To find the price per pound of apples, we divide the total cost of the apples by the weight of the apples.

To determine whether the price per pound of apples is greater or less than $1, we need to divide the total cost of the apples by the weight of the apples. The question states that Laura bought 2.1 pounds of apples. To find the total cost, we can use the information given in the reference:

10 apples × 50 cents each = $5.00 spent on apples in 2001.

Dividing $5.00 by 2.1 pounds gives us the price per pound of apples Laura bought, which is approximately $2.38. Therefore, the price per pound of apples is greater than $1.

Step-by-step explanation:

De tanque lleno de agua,se utilizan las dos quintas partes y luego los tres cuartos del resto. Si aún quedan 240 litros ¿cuántos litros tiene?

2/5- 3/4=-0.35

tienes 120 galones más el 0.35

120+0.35=120.35

que tengas un buen día!!!!!!!!!!!!!

The initial amount of water in the tank was 1600 liters.

Let's denote the initial amount of water in the tank as W.

First, two-fifths of the water are used, leaving [tex]\(\frac{3}{5}\)[/tex] of the water remaining.

[tex]\[\text{Remaining amount} = \frac{3}{5} \times W\][/tex]

Then, three-quarters of the remaining water are used, leaving \(\frac{1}{4}\) of the remaining water.

[tex]\[\text{Final amount} = \frac{1}{4} \times \left(\frac{3}{5} \times W\right)\][/tex]

According to the problem, the final amount is 240 liters:

[tex]\[\frac{1}{4} \times \left(\frac{3}{5} \times W\right) = 240\][/tex]

Now, solve for W:

[tex]\[\frac{3}{5} \times W = 240 \times 4\][/tex]

[tex]\[\frac{3}{5} \times W = 960\][/tex]

[tex]\[W = \frac{960 \times 5}{3}\][/tex]

[tex]\[W = 1600\][/tex]

So, the initial amount of water in the tank was 1600 liters.
