Answer:

V = 396 cm³

Step-by-step explanation:

the volume (V) of the prism is calculated as

V = Ah ( A is the area of the triangular face and h the height of prism )

A = [tex]\frac{1}{2}[/tex] bh ( b is base and h perpendicular height )

here b = 9, h = 8 , then

A = [tex]\frac{1}{2}[/tex] × 9 × 8 = 4.5 × 8 = 36 cm² , so

V = 36 × 11 = 396 cm³

Answer:

third side ≈ 19.8

Step-by-step explanation:

using Pyjthagoras' identity in the right triangle.

the square on the hypotenuse x is equal to the sum of the squares on the other 2 sides, that is

x² = 13² + 15² = 169 + 225 = 394 ( take square root of both sides )

x = [tex]\sqrt{394}[/tex] ≈ 19.8 ( to the nearest tenth )

Answer:

k = 60°

Step-by-step explanation:

y and z are parallel with each other against x line.

So we can make (2k+11)° = 131° and then solve for k.

2k + 11 = 131°

2k = 131° - 11°

2k = 120°

k = 60°

Answer:

57/10 is the simplest form

Step-by-step explanation:

To divide fractions you need to do the reciprocal rules.

You also need to convert any mixed numbers to improper to make them easier to divide.

4 3/4 and 5/6 are your fractions.

4 3/4 converted into an improper fraction is 19/4

This is because the rule with this is that you take your whole number multiply it by the denominator and take the product and add it to the numerator.

19/4 divided by 5/6.

You need to flip 5/6 to 6/5 due to the reciprocal rules and also change the division sign to a multiplication sign.

19/4 x 6/5

You can multiply straight across!

19 x 6 and 4 x 5

19 x 6 = 114

4 x 5 = 20

Our answer: 114/20

We still need to simplify this answer

We can divide this result into 2/2.

114/20 = 57/10

57/10 is the simplest form. If you were to divide more, you will get involved with decimals.

Answer:

192π

Step-by-step explanation:

cylinder volume is base times height

2πr^2 = base = 64π

height = 3

64π*3 = 192π

The volume of the given cylinder is 192π cubic units. Therefore, option C is the correct answer.

Volume is the measure of the capacity that an object holds.

Formula to find the volume of the object is Volume = Area of a base × Height.

From the given figure, radius of a cylinder = 8 units and radius of a cylinder = 3 units.

We know that, volume of a cylinder is πr²h.

Now, volume = π×8²×3

= π×64×3

= 192π cubic units.

Therefore, option C is the correct answer.

Answer:

4,000

Step-by-step explanation:

To round a number, take the place next to the one you wish to round and look to see if it is four or under, or five or up. In this case, 2 is less than 5 so we will be rounding down towards the nearest integer, which is 4. Also, all places after the place value you round will become zero. So, 4,000 rounded to the thousands place is 4,000.

Answer:

Sale Price = $36

Step-by-step explanation:

To find the sale price, you need to find what 10% of the original price is. 10% of $45 is $4.50. Now we need to find what 20% is, 20% is double 10% so we multiply the answer we got by 2. This equals to $9. The question is asking for the sale price, to find it you have to subtract $9 (the discount) from $45 (regular price). The answer you should get is $36.

Equation:
$45 ÷ 10 = $4.50
$4.50 × 2 = $9
$45 - $9 = $36

Using proportions, it is found that it will take 4 hours for Phoebe to catch Candice.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

Given their velocities, and the fact that they travel in the same direction, each hour, Phoebe gets 10 mph closer to Candice.

The initial distance is of 40 miles, 40/10 = 4, hence it will take 4 hours for Phoebe to catch Candice.

Answer:

Step-by-step explanation:

It is given that the area of a circle is 36.43cm² and we have to find the length of the radius.

So, first of we must know this formula :

⇒ πr² = Area(Circle)

Now, Substituting the given values in the formula :

⇒ 3.14 × r² = 36.43

⇒ r² = 36.43/3.14

⇒ r² = 11.60

⇒ r = √11.60

⇒ r = 3.40

Therefore,

Hey ! there

Answer:

Step-by-step explanation:

In this question we are given with area of circle that is 36.43 cm² . And we are asked to find the length of radius of circle rounded to two decimal points .

We know that ,

[tex] \qquad \quad \frak{Area_{(Circle)} = \pi r {}^{2} } \quad \bigstar[/tex]

Where ,

Solution : -

According to question , area of Circle is equal to 36.43 . So ,

[tex] \longrightarrow \qquad \: \pi r {}^{2} = 36.43[/tex]

Step 1 : Substituting value of π :

[tex] \longrightarrow \qquad \:3.14 \times r {}^{2} = 36.43[/tex]

Step 2 : Transposing 3.14 to right side :

[tex] \longrightarrow \qquad \: r {}^{2} = \cancel{\dfrac{36.43}{3.14} }[/tex]

On dividing 36.43 by 3.14 , We get :

[tex] \longrightarrow \qquad \: r {}^{2} = 11.60[/tex]

Step 3 : For removing square from r , We are applying root on both sides :

[tex] \longrightarrow \qquad \: \sqrt{r {}^{ 2 }} = \sqrt{ 11.60}[/tex]

We get :

[tex] \longrightarrow \qquad \:r = \sqrt{11.60} [/tex]

Step 4 : Finding square root of 11.60 , We get :

x^3 + 9 x^2 + 21 x + 9 = (x^2 + 6 x + 3)×(x + 3) + 0

Step-by-step explanation:

Set up the polynomial long division problem with a division bracket, putting the numerator inside and the denominator on the left:

x + 3 | x^3 | + | 9 x^2 | + | 21 x | + | 9

To eliminate the leading term of the numerator, x^3, multiply x + 3 by x^2 to get x^3 + 3 x^2. Write x^2 on top of the division bracket and subtract x^3 + 3 x^2 from x^3 + 9 x^2 + 21 x + 9 to get 6 x^2 + 21 x + 9:

| | | x^2 | | | |

x + 3 | x^3 | + | 9 x^2 | + | 21 x | + | 9

| -(x^3 | + | 3 x^2) | | | |

| | | 6 x^2 | + | 21 x | + | 9

To eliminate the leading term of the remainder of the previous step, 6 x^2, multiply x + 3 by 6 x to get 6 x^2 + 18 x. Write 6 x on top of the division bracket and subtract 6 x^2 + 18 x from 6 x^2 + 21 x + 9 to get 3 x + 9:

| | | x^2 | + | 6 x | |

x + 3 | x^3 | + | 9 x^2 | + | 21 x | + | 9

| -(x^3 | + | 3 x^2) | | | |

| | | 6 x^2 | + | 21 x | + | 9

| | | -(6 x^2 | + | 18 x) | |

| | | | | 3 x | + | 9

To eliminate the leading term of the remainder of the previous step, 3 x, multiply x + 3 by 3 to get 3 x + 9. Write 3 on top of the division bracket and subtract 3 x + 9 from 3 x + 9 to get 0:

| | | x^2 | + | 6 x | + | 3

x + 3 | x^3 | + | 9 x^2 | + | 21 x | + | 9

| -(x^3 | + | 3 x^2) | | | |

| | | -(6 x^2 | + | 18 x) | |

| | | | | 3 x | + | 9

| | | | | -(3 x | + | 9)

| | | | | | | 0

The quotient of (x^3 + 9 x^2 + 21 x + 9)/(x + 3) is the sum of the terms on top of the division bracket. Since the final subtraction step resulted in zero, x + 3 exactly divides x^3 + 9 x^2 + 21 x + 9 and there is no remainder.

| | | x^2 | + | 6 x | + | 3 | (quotient)
