Answer:

[tex]d=\frac{2M}{3}[/tex]

Step-by-step explanation:

Switch sides

[tex]\frac{1}{2}\left(d\cdot \:1+d\cdot \:2\right)=M[/tex]

Multiply both sides by 2 to remove the fraction

[tex]2\cdot \frac{1}{2}\left(d\cdot \:1+d\cdot \:2\right)=2M[/tex]

Then simplify

[tex]3d=2M[/tex]

[tex]\frac{3d}{3}=\frac{2M}{3}[/tex]

[tex]d=\frac{2M}{3}[/tex]

Answer:

11 feet

Step-by-step explanation:

The solution for the absolute value equation is height = 2.5 feet, which lies between the minimum and maximum height restrictions of 2 feet and 3 feet for the Swan Ride.

We have,

The absolute value equation representing the height restrictions for the Swan Ride would be:

| h - 2 | = 3 - h

To solve this equation:

Solving this equation gives:

For height - 2 ≥ 0:

height - 2 = height - 3

-2 = -3 (no solution in this case)

For height - 2 < 0:

-(height - 2) = height - 3

-height + 2 = height - 3

2 + 3 = height + height

5 = 2 * height

height = 5 / 2

height = 2.5 feet

Thus,

The solution for the absolute value equation is height = 2.5 feet, which lies between the minimum and maximum height restrictions of 2 feet and 3 feet for the Swan Ride.

Answer:

Neither

Step-by-step explanation:

180-59-61 = 60 degrees

It is an scalene triangle = no equal angles

Step-by-step explanation:

option C is correct ( neither).

because the other side is 180-61-59 = 60.

therefore, the three angles are different, and it's a scalene triangle.

Answer:

15q

Step-by-step explanation:

Answer:

5( 15q² - 5q + 3 )

Step-by-step explanation:

Step 1: - Multiply the numbers and use commutative property to reorder the terms.

Step 2: - Distribute 2 through the parantheses.

Step 3: - Factor out 5 from the expression.

3 + 0.75x = 5.25 - 0.25x

0.75x = 2.25 - 0.25x

x = 2.25

3 + 0.75(2.25) = 5.25 - 0.25(2.25)

3 + 1.6875 = 5.25 - 0.5625

4.6875 = 4.6875

They are equal

If pairings of corresponding sides and corresponding angles are equal, two triangles are said to be congruent. They are the exact same size and form.

Consider triangles SQT and SRQ

Angle RSQ = Angle QST

Angle SRQ = Angle STQ  (90 degrees)

side SQ = side SQ (common)

By Angle Angle Side (AAS) property , both triangles are congruent.

Thus, Side RQ = Side QT

Substitute the values,

3x + 12 = 4x - 8

4x - 3x = 12 + 8

x = 20

Put x =20 in RQ

RQ = 3x + 12

     = 3×20 + 12

RQ = 72

Therefore, the Side of Triangle RQ = 72 units.

Ratio of the volumes of the smaller cake to the larger cake is A: 8 : 27.

Volume of a three dimensional shape is the space occupied by the shape.

Given are two cakes in the form of a rectangular prism.

Volume of the rectangular prism = Length × Width × Height

Volume of the smaller cake = 12 × 8 × 2

                                              = 192 inches³

Volume of the larger cake = 18 × 12 × 3

                                            = 648 inches³

Ratio of volumes = 192 / 648

                            = 24 / 81 [Dividing by 8]

                            = 8 / 27 [Dividing by 3]

Hence the required ratio is 8 : 27.
