Here given:

using volume formula:

π(15)²(320)

72000π

72000(3.14)          [ take π as 3.14 ]

226,080 cm³

Answer:

Step-by-step explanation:

Given:

Radius = 30/2 = 15cm

Height = 320cm

=> The volume of cylinder = πr²h

=> π×15×15×320

=> 3.14×225×320

=> 226,080cm³

Answer:

[tex]2(3) {}^{x} [/tex]

Step-by-step explanation:

[tex]y = ab {}^{x} [/tex]

We know that when x=1, y=6

[tex]6 = a {b}^{1} [/tex]

x=2, y=18

[tex]18 = a {b}^{2} [/tex]

Notice that if we divide

[tex] \frac{ {ab}^{2} }{ab} = b[/tex]

So if we divide 18 and 6, that will give us our common ratio.

[tex] \frac{18}{6} = 3[/tex]

So our common ratio is 3.

So know we have

[tex]a(3) {}^{x} [/tex]

Plug in one of the points to find a.

[tex]6 = a(3)[/tex]

[tex]a = 2[/tex]

So the equation. we have

[tex]2 \times ({3}^{x} )[/tex]

L : J

2:3

so Lara has 2 shares

2 shares = 8

what is one share

type in comments

and then I will explain the rest

The amount of the Joan's share will be $12.

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

Algebra is the study of graphic formulas, while logic is the interpretation among those signs.

A sum of money is divided between Laura and Joan in the ratio 2:3.

Laura’s share is $8.

Let J be the amount of Joan's share and L be the amount of Laura's share.

Then the amount of Joan's share will be

L / J = 2 / 3

8 / J = 2 / 3

By the cross multiplication, then the equation will be

2J = 8 x 3

2J = 24

 J = 24 / 2

 J = $12

The amount of the Joan's share will be $12.

Answer:

411

Step-by-step explanation:

Because it has a 4 , 1 , and a 1

meaning the first number can't be 1 so it is automatically a 4.

and then the only 2 numbers left is 2 one's so you have to put them in their also automatically and 4 is asking 1 to round up can it.

411 can't round up,it would round down because 1 is 4 and below so it can't go up and goes down.

so 4 1 1 can't go up the number would have to be 450 to go to 500 but because it is 411 it goes down to 400 because it is rounded to 400.

Hope this helps have a awesome day:)

Answer:

The radical that is equal to ∛54 is 3∛2.

Step-by-step explanation:

Given

∛54

We need to find the radical that is similar to ∛54, we need to break down the radicand 54, into smaller numbers, therefore, take the LCM of the number,

54 = 2 x 3 x 3 x 3

As we are taking the cube root, therefore, we need numbers that are repeating thrice.

Thus, the radical can be written as,

[tex]\sqrt[3]{54} =\sqrt[3]{2x 3x 3x 3} \\\\\sqrt[3]{54} =3\sqrt[3]{2}[/tex]

Hence, the radical that is equal to ∛54 is 3∛2

Answer:

[tex]3\sqrt[3]{2}[/tex]

Step-by-step explanation:

Original expression:

[tex]\implies \sqrt[3]{54}[/tex]

Factorize 54 using prime factorization:

[tex]\implies \sqrt[3]{2 \cdot 3^3}[/tex]

Apply radical rule: [tex]\sqrt[n]{ab} =\sqrt[n]{a} \cdot \sqrt[n]{b}[/tex]

[tex]\implies \sqrt[3]{2} \cdot \sqrt[3]{3^3}[/tex]

Apply radical rule: [tex]\sqrt[n]{a^n} =a[/tex]

[tex]\implies \sqrt[3]{2} \cdot 3[/tex]

[tex]\implies 3\sqrt[3]{2}[/tex]

Answer:

[tex]u\cdot v=32[/tex]

Step-by-step explanation:

Assuming [tex]u[/tex] and [tex]v[/tex] are vectors, their dot product is [tex]u\cdot v[/tex] where [tex]u_1v_1 + u_2v_2[/tex]:

[tex]u\cdot v=u_1v_1+u_2v_2=(2)(8)+(-8)(-2)=16+16=32[/tex]

Therefore, [tex]u\cdot v=32[/tex]

Step-by-step explanation:

Cosine of 35 degrees= adjacent side /hypotenuse.

Move everything to one side and factorize by grouping.

x⁴ - 4 = x³ + 2x

x⁴ - x³ - 2x - 4 = 0

(x⁴ - 4) - (x³ + 2x) = 0

(x² - 2) (x² + 2) - x (x² + 2) = 0

(x² - x - 2) (x² + 2) = 0

(x - 2) (x + 1) (x² + 2) = 0

Then

x - 2 = 0   or   x + 1 = 0   or   x² + 2 = 0

x = 2   or   x = -1   or   x² = -2

If x is real, then the third case has no solution. Then x = 2 or x = -1. Otherwise, we can solve over the complexes and include x = ± √2 i where i = √(-1).

Find 2% of what she sold by multiplying the amount she sold by 2%:

5250 x 2% = 5250 x 0.02 = $105

Now add that to her monthly salary:

3462 + 105 = $3,567

a + z + l = 720

l = 2z = 2a - 80

4z + 40 = 720

The answer is 4.94, rounded.

Step-by-step explanation:

The pythagorean theorem is : a^2+b^2=c^2

Inserting our numbers:

3.4^2+b^2=6^2

We can find 'B' by finding the other two numbers and subtracting 'A', from 'C'.

3.4*3.4= 11.56

6*6= 36

36-11.56= 24.44

Answer:

113.04

Step-by-step explanation:

The area of the square is 144 which means the length of each side of the square is 12. When the length on one side is 12 the radius of the circle will be half of the whole length. In this case, it means the radius is going to be 6. When we find the radius, we can use the formula r^2pie to find the area for the circle.

6 * 6 * 3.14

= 113.04

Answer:

Area = 113.04 in²

Step-by-step explanation:

Given:

Area of a square

[tex]\sf A=s^2\quad \textsf{(where s is the side length)}[/tex]

Substitute the given area of the square into the formula and solve for s:

[tex]\begin{aligned}\sf A & = \sf s^2\\\implies \sf 144 & = \sf s^2\\\sf \sqrt{144} & = \sf \sqrt{s^2}\\\sf 12 & = \sf s\\\implies \sf s & = \sf 12\:\:inches\end{aligned}[/tex]

From inspection of the given diagram, the side length of the square is equal to the diameter of the circle.  Therefore, the diameter is 12 inches.

Radius of a circle

[tex]\sf r = \dfrac{1}{2}\:d\quad \textsf{(where d is the diameter)}[/tex]

Substitute the found diameter into the formula and solve for r:

[tex]\begin{aligned}\sf r & = \sf \dfrac{1}{2}\:d\\\implies \sf r & = \sf \dfrac{1}{2}(12)\\\sf r & = \sf 6\:\:inches\end{aligned}[/tex]

Area of a circle

[tex]\sf A= \pi r^2 \quad \textsf{(where r is the radius)}[/tex]

Substitute the found radius into the formula and solve for A:

[tex]\begin{aligned}\sf A & = \sf \pi r^2\\\implies \sf A & = \sf 3.14 \cdot 6^2\\& = \sf 3.14 \cdot 36\\& = \sf 113.04\:\: in^2\end{aligned}[/tex]

Therefore, the approximate area of the paper circle is 113.04 in².

The sum of -5a and 3 is greater than 1

Answer:

Its solving equations with variable on both sides

Step-by-step explanation:

Example: 8a = 3a+25

You have to make a variable on the both side

So.....

8a-3a = 3a+25-3a

And then solve it. So the last thing you will have is

5a = 25

If you want to the simplest form...divide 25 with 5

a = 25/5

a = 5
