Answers

Answer:

Option 3. (23, 14)

Step-by-step explanation:

In this figure, solution of the system of equations is the point of intersection of the equations representing two lines.

Or common points lying on both the lines will be the solutions of the system of equations.

In the given graph approximate value of x - coordinates = 23

and approximate value of y - coordinates = 14

Which is the largest value of the 5 numbers below
13.05 13.5 13.06 13.45 13.07

Answers

Answer:it is 13.45

Step-by-step explanation:

Final answer:

The largest value among the provided numbers is 13.5. In decimal numbers, the higher the value after the decimal point, the larger the fraction of a whole number it represents. Therefore, 13.5, with '.5' after the decimal point, represents the largest value.

Explanation:

In order to find the largest value among the given numbers, it will be useful to first understand how decimal numbers work. Decimal numbers are a method of writing fractions in a way that is easier to work with. In a decimal number, the number after the decimal point represents a fraction of a whole number. The larger this number, the larger the fraction of the whole number it represents.

In your list, you have five numbers: 13.05, 13.5, 13.06, 13.45, and 13.07. If we compare just the numbers after the decimal point, we'll see that '.5' is the largest. Therefore, 13.5 is the largest number among your list.

3/4(x-12)=12

What is x? What is Y?

Answers

Answer:

x = 28y = 32

Step-by-step explanation:

3/4(x-12)=12

3/4x - 3/4(12) = 12

3/4x - 9 = 12

3/4x = 12 + 9

3/4x = 21

1/4x = 7

x = 28

3/4y - 12=12

3/4y = 12 + 12

3/4y = 24

Answer:

Answer:

The slope is 3/2

Step-by-step explanation:

Slope is calculated by rise over run so there are three points for you. You start from a point that hits the line then you go up 3 units and across 2 units and you hit the next point. That means the slope is 3/2

Hope this helps and I tried my best on explaining it's hard without being able to show it to you!

Answer:

The slope of given line = 2/3

Step-by-step explanation:

Let (x₁, y₁) and (x₂, y₂) be the two points on a line, the slope of the line is given by,

Slope = (y₂ - y₁)/(x₂ - x₁)

Form the figure we get some coordinates points

(2, 3),  (4,6) , (6, 9)

To find the slope of  line

Consider two points

(x₁, y₁)  = (2, 3) and  (x₂, y₂) = (4, 6)

Slope = (y₂ - y₁)/(x₂ - x₁) = (4 - 2)/(6 - 3) = 2/3

Therefore the slope of given line = 2/3

x is 110% of 10, y% of 50 is 3.5

Answers

For the expression "X is 110% of 10," X is equal to 11.

For the expression "y% of 50 is 3.5," the value of y is 7.

From the information given, we can solve for both x and y:

1. Finding x:

"X is 110% of 10" means that x is equal to 110% multiplied by 10.

110% can be written as a decimal by dividing by 100: 110/100 = 1.1

Therefore, x = 1.1 * 10 = 11.

2. Finding y:

"y% of 50 is 3.5" means that y% multiplied by 50 is equal to 3.5.

To solve for y%, we can rearrange the equation: y% = 3.5 / 50.

To express y as a percentage, we can multiply by 100: y = (3.5 / 50) * 100 = 7.

Complete question:

Calculate the percentage: X is 110% of 10, y% of 50 is 3.5

Final answer:

We calculated x by determining that it's 110% of 10, which results in x being 11. Then, we solved for y by understanding that y% of 50 equals 3.5, leading to the conclusion that y is 7.

Explanation:

To solve for x, we consider that it is 110% of 10. To convert a percentage into a decimal, we divide by 100, so 110% becomes 1.10. Therefore, x = 1.10 × 10. After multiplying, we get x = 11.

For the second part, we have y% of 50 is 3.5. The equation can be represented as (y/100) × 50 = 3.5. To find y, we divide both sides by 50 and then multiply by 100 to get y = (3.5 × 100) / 50. Solving for y, we find y = 7.

We have to multiply 58 and 12.

[tex]a\times b\\=a\times (c+d)\\=(a\times c) + (a\times d)[/tex]

A square with sides of 15 cm is enlarged in a ratio 3:4. What is the area of the resulting square?​

Answers

Final answer:

When a square with 15 cm sides is enlarged by a ratio of 3:4, the resulting square has a side length of 20 cm, and consequently, an area of 400 cm².

Explanation:

If a square with sides of 15 cm is enlarged in a ratio of 3:4, we first need to determine the new length for the sides of the resulting square. To do this, we take the original side length (15 cm) and multiply it by the scale ratio.

The scale ratio is 3:4 which means for every 3 units of the original, the new square will have 4 units. Therefore, we calculate the new side length as follows:

Original side length = 15 cmScale factor = 3:4New side length = (15 cm) × (4/3) = 20 cm

Now, to find the area of the resulting square, we square the new side length:

Area = side × side = 20 cm × 20 cm = 400 cm²

So, the area of the resulting square is 400 cm².

Step-by-step explanation:

Answer:

0          4

20       0

-10       6

Step-by-step explanation:

x + 5y = 20

5y = -x + 20

 y = -1/5 x + 4

so

when x = 0,

y = -1/5 (0) + 4

y = 4

when y = 0 then

0 = -1/5 x + 4

-4 = -1/5 x

x = (-4) (-5)

x = 20

when y = 6 then

6 = -1/5 x + 4

2 = -1/5 x

x = 2 * (-5)

x = -10

A credit card company charges a customer $18 interest on a $90 purchase. What is the interest rate?

Answers

Final answer:

The interest rate charged by the credit card company for a $90 purchase with an $18 interest charge is calculated to be 20%.

Explanation:

To calculate the interest rate charged by the credit card company on a $90 purchase with an $18 interest charge, we need to use the formula for interest rate:

Interest Rate = (Interest / Principal) × 100

Applying the given values:

Interest Rate = ($18 / $90) × 100

Interest Rate = 0.2 × 100

Interest Rate = 20%

The interest rate the credit card company charged on the purchase is 20%.

an=−6−5n

Answers

Answer:

an = 2 - 3n ⇒ The third answer

Step-by-step explanation:

∵ a1 = -1

∵ a2 = -4

∵ a3 = -7

∵ a2 - a1 = -4 - -1 = -3

∵ a3 - a2 = -7 - -4 = -3

∴ It is an arithmetic sequence with

  1st term = -1 and constant difference = -3

∵ The rule of any arithmetic is: an = a + (n - 1)d

∵ a = -1 and d = -3

∴ an = -1 + (n - 1)(-3)

∴ an = -1 - 3n + 3

an = 2 - 3n ⇒ The third answer

The student's algebraic expression simplifies to 48 - 12y.

The question involves simplifying an algebraic expression. Let's solve it step by step:

Distribute the 6 to each term inside the first parentheses: 6(7) / (- 6(3y)).

Do the same for the second parentheses: 6(y) + 6(1).

Combine like terms by adding or subtracting the coefficients.

Let's simplify the expression now:

6(7) - 6(3y) + 6(y) + 6(1).

42 - 18y + 6y + 6.

Combine the terms with y: -18y + 6y = -12y.

The final simplified expression is 42 - 12y + 6.

Combine the constant terms: 42 + 6 = 48.

The final answer is 48 - 12y.

Answer:

[tex]40\pi\text{ cubic feet}[/tex]

Step-by-step explanation:

Given,

The diameter of the pipe = 24 inches,

⇒ The diameter of the section = 24 inches

And, it is laid in 40 foot section,

So, the height of each section = 40 feet,

Since, the shape of a pipe is cylindrical,

The volume of a cylinder is,

[tex]V=\pi (r)^2 h[/tex]

Where, r is the radius,

h is its height,

Here, r = [tex]\frac{24}{2}[/tex] = 12 inches = 1 feet,

Also, h = 40 foot,

Thus, the quantity of water hold by the section = Volume of the section
