The solution is

Answers

Answer 1

Answer:

x = -3

y = -6

Step-by-step explanation:

[tex]y = 6 + 4x \\ - 5x - (6 + 4x) = 21 \\ - 9x - 6 = 21 \\ - 9x = 27 \\ x = - 3 \\ y = 6 + (4 \times - 3) = - 6[/tex]

The angles are on the same side of the transversal.  They are corresponding angles, so they are equal. Put algebraically

4a = 2a + 50                Subtract 2a from both sides.

4a-2a = 2a-2a + 50     Combine

2a = 50                        Divide by 2

2a/2 = 50/2

a = 25

A rectangular swimming pool is 8 ft deep. One side of the pool is 4.5 times longer than the other. The amount of water needed to fill the swimming pool is 2304 cubic feet. Find the dimensions of the pool.

The smaller dimension of the pool is____ft and the larger dimension is____ft

Answers

Answer:

length= 42, width=12, depth=8

Step-by-step explenation:

The smaller dimension of the pool is 8 ft and the larger dimension is 36 ft

The length of the rectangle = 8 feet

The width of the rectangle = 36 feet

What is the Volume of a Rectangle?

The volume of the rectangle is given by the product of the length of the rectangle and the width of the rectangle and the height of the rectangle

Volume of Rectangle = Length x Width x Height

Volume of Rectangle = Area of Rectangle x Height

Given data ,

The volume of the rectangle is V = 2304 feet³

Let the length of the rectangle be = A

One side of the pool is 4.5 times longer than the other

So , the width of the rectangle be = 4.5A

Now , on simplifying the equation , we get

Volume of Rectangle = Length x Width x Height

Substituting the values in the equation , we get

Volume of Rectangle = 8 x A x 4.5A

36A² = 2304

Divide by 36 on both sides of the equation , we get

A² = 64

Taking square roots on both sides of the equation , we get

A = 8 feet

Therefore , the width of the rectangle = 4.5 A = 36 feet

Hence , the dimensions of the rectangle is 8 x 36 x 8

1-La funcion lineal que pasa por el punto (3,6) tiene como expresion:
a) Y=3x+6
b) Y=6x-3
c) Y=2x

Answers

Answer:

Creo que es b

Step-by-step explanation:

The linear function that passes through the point (3,6) is given by: Option C: [tex]y = 2x[/tex]

How to know if a point lies in the graph of a function?

All the points (and only those points) which lie on the graph of the function satisfy its equation.

Thus, if a point lies on the graph of a function, then it must also satisfy the function.

Checking all the options to see if (3,6) lies on them:

Case 1: [tex]y = 3x + 6[/tex]

Usually points are of the form (x,y). Thus, we have: (x,y) = (3,6) means x = 3, and y = 6.

Putting these values in the equation, we get:

[tex]y = 3x + 6\\6 = 3(3) + 6\\6 = 9 + 6\\6 = 15[/tex]

This is wrong. Thus, the point (3,6) doesn't satisfy this equation, and therefore, doesn't lie on its graph.

Case 2: [tex]y = 6x - 3[/tex]

Putting x = 3, y = 6 in this equation, we get:

[tex]y = 6x - 3\\6 = 6(3) - 3\\6 = 18 - 3 \\6 = 12[/tex]

This is wrong. Thus, the point (3,6) doesn't satisfy this equation, and therefore, doesn't lie on its graph.

Case 3: [tex]y = 2x[/tex]

Putting x = 3, y = 6 in this equation, we get:

[tex]y = 2x\\6 = 3(2)\\6 = 6[/tex]

This is correct. Thus, the point (3,6) satisfy this equation, and therefore, lies on its graph.

Thus, the linear function that passes through the point (3,6) is given by: Option C: [tex]y = 2x[/tex]

Dilate quadrilateral ABCD again with the origin as the center of dilation and a scale factor of -0.5. Note the side lengths of the corresponding sides in each quadrilateral. Round your answers to the hundredths place. Verify that the ratio of each side length of A′1B′1C′1D′1 to the corresponding side length of ABCD is equal to the dilation factor.

Answers

Answer:

A' (-0.20, -0.75)

B' (-1.50, -1.50)

C' (-1.79, -0.29)

D' (-10.45, -0.20)

Step-by-step explanation:

you just need to multiply all the points by -0.5, sorry not sure how to verify the ratios for the sidelength tho

The coordinates of the dilated quadrilateral are A'(-0.2, -0.75), B'(-1.5, -1.5), C'(-1.79, -0.285) and D'(-1.045, -0.2) and the ratio of each side length of A'B'C'D' to the corresponding side length of ABCD is equal to the dilation factor.

What is Graph?

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

We need to Dilate quadrilateral ABCD again with the origin as the center of dilation and a scale factor of -0.5.

The side lengths of the corresponding sides in each quadrilateral.

A(0.4, 1.5)

B(3, 3)

C(3.58, 0.57)

D(2.09, 0.4)

The scale factor is -0.5.

Now A'=(-0.4×0.5, -1.5×0.5)

=(-0.2, -0.75)

B'=(3×-0.5, 3×-0.5)

=(-1.5, -1.5)

C'=(3.58×-0.5, 0.57×0.5)

C'=(-1.79, -0.285)

D'=(2.09×-0.5, 0.4×-0.5)

D'=(-1.045, -0.2)

Hence, the coordinates of the dilated quadrilateral are A'(-0.2, -0.75), B'(-1.5, -1.5), C'(-1.79, -0.285) and D'(-1.045, -0.2) and the ratio of each side length of A'B'C'D' to the corresponding side length of ABCD is equal to the dilation factor.

For friends split equally a lunch bill of $36.96 +20% tip how much did each person pay?

Answers

Answer:

Step-by-step explanation:

Well first we need to add the tip in order to find the total amount of cash needed to be paid.

0.3696 x 20 = 7.392

So lets just say $7.39

Add that to the sub total which is 36.96

36.96 + 7.39 = $44.35

Now, in order to figure out how much each friend should pay, we divide the total by 4.

44.35/4 = 11.0875

So lets just say $11.09

So each friend should pay about $11.09
