What is the missing value? The Volume is 5120 m^3

Answers

Answer 1

Answer: I think that the missing value is 16m.

I just multiplied two other numbers with 20 and 20 x 16 x 16 = 5120

I hope this was right.

Answer 2

Answer:

Answer:

Step-by-step explanation:

V= $\pi$ r^2

5120= $\pi r^(2)$ x20

5120/20 = 256

$√(256)$ =16

16+16 ( 16x2) = 32

32in.

In the 40-60-90 triangle below, side s has a length of ___ and side q has a length of __

Answers

Answer:

D. $5,\: 5\sqrt 3$

Step-by-step explanation:

According to the 30°-60°-90° triangle theorem:

Side opposite to 30° is half of hypotenuse and side opposite to 60° is $(\sqrt 3)/(2)$ times of hypotenuse.

In the given figure:

side s is opposite to 30° angle.

$\therefore s = (1)/(2) * 10= 5\n$

side q is opposite to 60° angle.

$\therefore q =(\sqrt 3)/(2) * 10= 5\sqrt 3\n$

x2 – x – 20 C) Prime

x2 – 9x – 20 D) (x – 2)(x + 10)

Answers

Answer:

Step-by-step explanation:

The given equation is:

$x^(2)-8x-20$

Simplifying the above equation, we get

$x^(2)-10x+2x-20$

$x(x-10)+2(x-10)$

$(x+2)(x-10)$

therefore, the equation $x^(2)-8x-20$ matches with (B) $(x+2)(x-10)$ .

The given equation is :

$x^(2)+8x-20$

Simplifying the above equation, we get

$x^(2)+10x-2x-20$

$x(x+10)-2(x+10)$

$(x-2)(x+10)$

therefore, the equation $x^(2)+8x-20$ matches with (D) $(x-2)(x+10)$

The given equation is:

$x^(2)-x-20$

Simplifying the above equation, we get

$x^(2)-5x+4x-20$

$x(x-5)+4(x-5)$

$(x+4)(x-5)$

therefore, the equation $x^(2)-x-20$ matches with (A) $(x+4)(x-5)$ .

The given equation is:

$x^(2)-9x-20$

This equation ca't be firther simplified or factorised, thus the equation $x^(2)-9x-20$ matches with (C) Prime.

the correct matches for the polynomials are:

A) (x – 5)(x + 4) matches with x^2 – x – 20.

B) (x – 10)(x + 2) matches with x^2 + 8x – 20.

C) Prime does not match any of the given terms.

D) (x – 2)(x + 10) matches with x^2 – 9x – 20.

How did we arrive at these assertions?

Let's factor each trinomial and match them with their factored forms:

x² – 8x – 20:

To factor this trinomial, we need to find two numbers that multiply to give -20 and add up to -8. The numbers that satisfy these conditions are -10 and 2. Therefore, the factored form is (x – 10)(x + 2). Match: A.

x² + 8x – 20:

For this trinomial, we once again look for two numbers that multiply to give -20 and add up to 8. The numbers are -2 and 10. Hence, the factored form is (x – 2)(x + 10). Match: D.

x² – x – 20:

Here, we seek two numbers that multiply to give -20 and add up to -1. The numbers -5 and 4 satisfy these conditions. Thus, the factored form is (x – 5)(x + 4). Match: A.

x² – 9x – 20:

Similar to the previous trinomials, we search for two numbers that multiply to give -20 and add up to -9. The numbers are -10 and 1. So, the factored form is (x – 10)(x + 1). Match: B.

Matching the terms with their factored forms:

A) (x – 5)(x + 4) matches with x² – x – 20.

B) (x – 10)(x + 2) matches with x² + 8x – 20.

C) Prime does not match any of the given terms.

D) (x – 2)(x + 10) matches with x² – 9x – 20.

Therefore, the correct matches are:

A) (x – 5)(x + 4) matches with x² – x – 20.

B) (x – 10)(x + 2) matches with x² + 8x – 20.

C) Prime does not match any of the given terms.

D) (x – 2)(x + 10) matches with x² – 9x – 20.

Solve for x.
3(x + 5) - 2(x + 2) = 20

Answers

3(x + 5) - 2(x + 2) = 20

Distribute the 3 and -2.

x + 11 = 20

Subtract 11 on both sides

x = 9

Your final answer is x = 9.
