Find the volume of the composite solid. Round your answer to the nearest hundredth.

Answer:

The total is $38.1

Step-by-step explanation:

The tax is $2.1, The tip is $6.

Percentage is the part of the whole expressed in the fraction of hundred.

The total cost of the meal after the tip and tax is $38.1.

Percentage of a number or ratio expressed in the form of fraction of hundred.

Given information-

The total cost of meal before tax and tip is $30.

The total sales tax is 7%.

The tip added to the cost of meal is 20%.

As, the total sales tax is 7% and cost of the meal is $30. Thus the total sales tax amount is,

[tex]s_t=30\times\dfrac{7}{100} \\s_t=2.1[/tex]

Thus the amount of sales tax is 2.1.

As the the tip added to the cost of meal is 20% and the cost of the meal is 32.1 after the tax. Thus the amount of meal after the 20 % tip is,

[tex]s_t=30\times\dfrac{20}{100} \\s_t=6.00[/tex]

The amount of the tip of the meal after the tax is $6.00.

The cost of meal after the tip and tax is,

[tex]C=30+2.1+6\\C=38.1[/tex]

Hence the total cost of the meal after the tip and tax is $38.1.

Answer:

a = 2 [tex]\frac{1}{3}[/tex]

Step-by-step explanation:

Given

[tex]\frac{1}{3}[/tex] a = [tex]\frac{7}{9}[/tex]

Multiply both sides by 9 ( the LCM of 3 and 9 ) to clear the fractions

3a = 7 ( divide both sides by 3 )

a = [tex]\frac{7}{3}[/tex] = 2 [tex]\frac{1}{3}[/tex]

It should be 2 1/3......

Answer:

The size of angle y is 126°

Step-by-step explanation:

From the diagram of the regular polygons, we have;

One side of each pentagon lies along a side of the octagon

The interior angle of the octagon > The interior angle of the pentagon

Each interior angle of a regular pentagon = 108°

Each interior angle of a regular octagon = 135°

Therefore, ∠ABC = 135° - 108° = 27°

Similarly, ∠BAC = 135° - 108° = 27°

Therefore, by triangle the angle sum theorem, we have;

∠y = ∠ACB = 180° - ∠BAC - ∠ABC = 180° - 27° - 27° = 126°

The size of angle y, ∠y = 126°.

Answer:

The correct answer is: Option D: [tex]t = 5s + \frac{s}{2}[/tex]

Step-by-step explanation:

Given that

Weight of snail is s

We have to use the given statements to write the mathematical expression

The snail drank water 5 times of its weight

So the quantity of water will be 5s

And it ate half of its weight's food which will be s/2

The combined weight of water and food will be:

[tex]t = 5s + \frac{s}{2}[/tex]

Hence,

The correct answer is: Option D: [tex]t = 5s + \frac{s}{2}[/tex]

Answer:

2[tex]\sqrt{6}[/tex]

Step-by-step explanation:

Using the rule of radicals

[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] ⇔ [tex]\sqrt{ab}[/tex]

Simplifying the radicals

[tex]\sqrt{96}[/tex]

= [tex]\sqrt{16(6)}[/tex]

= [tex]\sqrt{16}[/tex] × [tex]\sqrt{6}[/tex] = 4[tex]\sqrt{6}[/tex]

[tex]\sqrt{24}[/tex]

= [tex]\sqrt{4(6)}[/tex]

= [tex]\sqrt{4}[/tex] × [tex]\sqrt{6}[/tex] = 2[tex]\sqrt{6}[/tex]

Thus

[tex]\sqrt{96}[/tex] + 2[tex]\sqrt{6}[/tex] - 2[tex]\sqrt{24}[/tex]

= 4[tex]\sqrt{6}[/tex] + 2[tex]\sqrt{6}[/tex] - 4[tex]\sqrt{6}[/tex] ← collect like terms

Answer:

So its is pretty straight forward (answer at the bottom)

First of all 2 sides of a parrleogram are the dame and the other 2 are different from the first but the opposites are the same

So lets start with The distance from home to bank

x+9 is the distance since its the opposite

Now the other side is 2x+1

The third side is x+9

the fourth side is x+5, it is different from 2x+1 but its just written differently.

Now add them all up

2x+1+x+9+x+5+x+9=

5x+24

So the amount fo meters are 5x+24

The distance covered by Amaia is 5x+24 meters.

A parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.

Given that, Amaia walks out and covers a distance in a shape of parallelogram,

Therefore, the opposite sides will be equal,

To find the distance covered we will find the perimeter of the parallelogrammical way,

P = x+9+x+9+x+5+2x+1

P = 5x+24

Hence, the distance covered by Amaia is 5x+24 meters.
