y=10x

Select the answer showing the ratio x:y

Answer:

x = 15.65

y = 3.5

Step-by-step explanation:

Step 1

Find the equation for x and y

Equation for x is given as

x² = 7( 7+28) ..........Equation 1

14(14 + y) = x²........ Equation 2

Solving for Equation 1

x² = 7( 7+28)

x² = 7(35)

x² = 245

x = √245

x = 15.65

From Equation 1 , x² has been determined to be 245

Therefore we substitute 245 for y in Equation 2

14(14 + y) = x²........ Equation 2

14(14 + y) = 245

196 + 14y = 245

14y = 245 - 196

14y = 49

y = 49 ÷ 14

y = 3.5

Answer:

x=72 x = 7 2

Step-by-step explanation:

Answer:

x=7/2

Step-by-step explanation:

First, distribute the 9 on the left side  

9(3-2x)=2(10-8x)  

(9*3)+(9*-2x)= 2(10-8x)

27-18x= 2(10-8x)

Next, distribute the 2 on the right side

27-18x=(2*10)+(2*-8x)

27-18x=20-16x

Now, move all the numbers to one side of the equation, and the variables to the other.

27-18x=20-16x

Add 18x to both sides

27-18x+18x=20-16x+18x

27=20+2x

Subtract 20 from both sides

27-20=20-20+2x

7=2x

Now all the variables are on one side, and the numbers are on the other. x is still not by itself. It is being multiplied by 2. To undo this, divide both sides by 2

7/2=2x/2

7/2=x

Answer:

[tex] volume = 2197 \pi~in.^3 \approx 6902.1~in.^3 [/tex]

Step-by-step explanation:

[tex] base~ area = 169 \pi~in.^2 [/tex]

The base of the cylinder is a circle.

The area of a circle is:

[tex] area = \pi r^2 [/tex]

We set the area equal to the formula and find the radius.

[tex] \pi r^2 = 169 \pi~in.^2 [/tex]

[tex]r^2 = 169~in.^2[/tex]

[tex]r = 13~in.[/tex]

The radius of the base is 13 inches. The height of the cylinder is also 13 inches.

[tex] volume = base~area \times height [/tex]

[tex]volume = 169 \pi~in.^2 \times 13~in.[/tex]

[tex] volume = 2197 \pi~in.^3 \approx 6902.1~in.^3 [/tex]

Answer:

-23

Step-by-step explanation:

-23 is the answer

The sum of the two integers if they are 5 units apart on the number line, and their product is 126 is -23

System of equations are equations that contain unknown variables with more than 1 equation.

Let the required integers be x and y.

If two negative integers are 5 units apart on the number line, then;

x - y = 5
x = 5  + y

If their product is 126, hence:

x y = 126

Substitute

5+y(y) = 126
5y + y^2 = 126
y^2 + 5y - 126 = 0

Factorize
y^2 + 14y - 9y - 126 = 0
y(y + 14) - 9(y + 14) = 0
y = 9 and  - 14

Since the integers are negative, hence;

x =  5 + y
x = 5 - 14
x = -9

Sum = -14 + (-9)
sum = -23

Hence the sum of the two integers is -23

Answer:

Option A) 0.588

Step-by-step explanation:

We are given the following in the question:

In triangle ABC

AC = 8 cm

AB = 13.6 cm

We have to find the sine ratio of angle B.

We define sine ratio of angle B as:

[tex]\sin B = \dfrac{\text{Perpendicular}}{\text{Base}}[/tex]

Putting values, we get,

[tex]\sin B = \dfrac{AC}{AB} = \dfrac{8}{13.6} = 0.588[/tex]

The correct ansqwer is

Option A) 0.588

The transformation (x, y) → (x, 2y) doubles the y-coordinates of the parallelogram ABCD vertices, resulting in a new parallelogram with doubled height and consequently doubled area, demonstrating that the change in height is proportional to the original height.

The question posed relates to the effect of a transformation on the coordinates of a parallelogram's vertices. Specifically, we look at the transformation (x, y) → (x, 2y), which stretches the y-coordinates of the vertices while keeping the x-coordinates unchanged. For the given parallelogram ABCD with vertices A(0, 0), B(1, 1), C(3, 1), and D(2, 0), we apply the transformation to each vertex:

The transformation doubles the height (y-coordinate) of the parallelogram, while the base (x-coordinate) remains the same. Consequently, the area of the parallelogram also doubles, confirming that the change in height is proportional to the original height. By applying the transformation to a simple geometric figure, students can visualize and understand the properties of transformations and their effects on the shapes.

Length: 7 units

Width: 1 unit

Step-by-step explanation:

The length of rectangle is 7 units.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

let the length of rectangle be x.

Then, width of the rectangle = x - 6

Also, Area of rectangle = 7 units

So, length x width = 7

x(x- 6)= 7

x² - 6x = 7

x² -6x -7 =0

x² -7x + x - 7=0

x( x- 7) +1 (x- 7)= 0

(x+ 1)(x- 7)=0

x= -1 or 7.

Hence, the length of rectangle is 7 units.

To find the length of Y in a right triangle given X = 6 cm and Z = 10 cm, we can use the Pythagorean theorem. By substituting the values into the formula Y = √(X² + Z²), we find that the length of Y is approximately 11.66 cm.

To find the length of Y, we can use the Pythagorean theorem. Since X and Z are the lengths of the legs of a right triangle, Y represents the length of the hypotenuse.

Using the formula: Y = √(X² + Z²), we can substitute the given values: Y = √(6² + 10²) = √(36 + 100) = √136 = 11.66 cm.

Therefore, the length of Y is approximately 11.66 cm.

We have been given that a person invests 5500 dollars in a bank. The bank pays 6.75% interest compound monthly. We are asked to find the time that will take the amount to 13,200 dollars.

We will use compound interest formula to solve our given problem.  

[tex]A=P(1+\frac{r}{n})^{nt}[/tex], where,

A = Final amount,

P = Principal amount,

r = Annual interest rate in decimal form,

n = Number of times interest is compounded per year,

t = Time in years.

[tex]6.75\%=\frac{6.75}{100}=0.0675[/tex]

Upon substituting our given values in above formula, we will get:

[tex]13200=5500(1+\frac{0.0675}{12})^{12\cdot t}[/tex]

[tex]13200=5500(1+0.005625)^{12\cdot t}[/tex]

[tex]13200=5500(1.005625)^{12\cdot t}[/tex]

[tex]\frac{13200}{5500}=(1.005625)^{12\cdot t}[/tex]

[tex]2.4=(1.005625)^{12\cdot t}[/tex]

Now we will take natural log on both sides.

[tex]\text{ln}(2.4)=\text{ln}((1.005625)^{12\cdot t})[/tex]

Using natural log property [tex]\text{ln}(a^b)=b\cdot \text{ln}(a)[/tex], we will get:

[tex]\text{ln}(2.4)=12t\cdot \text{ln}(1.005625)[/tex]

[tex]t=\frac{\text{ln}(2.4)}{12\cdot \text{ln}(1.005625)}[/tex]

[tex]t=13.00635[/tex]

Upon rounding to nearest tenth, we will get:

Factoring completely would give you the answer of ( x+5) (x^3 +4).

Step-by-step explanation:

The factor are (x³ + 4) and (x + 5).

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

[tex]x^4[/tex] + 5x³ + 4x + 20

We can find the common factor between [tex]x^4[/tex] and 5x³.

So,

x³ (x + 5) _____(1)

And,

We can find the common factor between 4x and 20.

So,

4 (x + 5) ______(2)

From (1) and (2),

x³ (x + 5) + 4 (x + 5)

= (x³ + 4) (x + 5)

Thus,

The factor are (x³ + 4) and (x + 5).

To rewrite the integral over an appropriate region G in the​ uv-plane, we need to use the given transformation x = u/v and y = uv. The region G is defined by certain constraints on u and v, which can be found by solving the inequalities derived from the boundaries of R in the xy-plane. Finally, we can set up and evaluate the double integral over G.

To rewrite the integral over an appropriate region G in the​ uv-plane, we need to use the given transformation x = u/v and y = uv. Let's consider each boundary of R separately:

Now, we need to find the region G in the uv-plane that corresponds to R in the xy-plane. The region G is defined by the following constraints: u^2 ≤ v, 9v ≥ u^2, uv ≤ u/v, and uv ≥ 4(u/v). Combining these constraints, we get u^4 ≤ v^2 ≤ 9u^3 and u^2 ≤ 4v. The boundaries of G can be found by solving these inequalities.

To evaluate the integral over G, we need to determine the limits of integration for u and v. Once we have the limits, we can set up the double integral of the function over G and evaluate it.

Answer: x > 5

Step-by-step explanation: To solve for x in this inequality, your goal is the same as it would be if you were solving an equation, to get x by itself on one side.

On the left the -8 +8 cancels out
