If x=12 what is that value of 5(x-4)

Answer:

7.2 minutes

Step-by-step explanation:

The formula to find the time using the radioactive decay rate formula is given as:

t = t½ × In(Nt/No)/-In2

Where

t½ = half life = 6 minutes

No = Initial Amount = 260 grams

Nt = Amount after decay

= 113 grams

Hence:

t = 6 × In(113/260)/-In2

t = 7.2131331036796 minutes

Approximately = 7.2 minutes

Answer:

x = 61

Step-by-step explanation:

0.5(x + 7) + 9 = 43

0.5x + 3.5 + 9.0 = 43

0.5x + 12.5 = 43.0

0.5x = 30.5

x = 30.5 / 0.5

x = 61

The solution to the value of x in the equation is 61

In a mathematical concept, an algebraic expression consists of variables, constants with their arithmetic operations.

From the given parameters

0.5(x + 7) + 9 = 43

Open brackets

0.5x + 3.5 + 9 = 43

0.5x + 12.5 = 43

0.5x = 43 - 12.5

0.5x = 30.5

x = 30.5/0.5

x = 61

Answer:

hypotenuse = 4.24

Step-by-step explanation:

sin θ = opposite / hypotenuse

sin 45 = 3[tex]\sqrt{2}[/tex]/ hypotenuse

0.707 = 3[tex]\sqrt{2}[/tex]/ hypotenuse

hypotenuse = 4.24

Answer:

| - 16 |

Step-by-step explanation:

The absolute value function always gives a positive value, that is

| - a | = | a | = a

Then

| 6 | = 6

| - 16 | = | 16 | = 16

Thus the largest number from the list is | - 16 |

x [tex]\geq[/tex] 433

explanation:

let m equal miles

0.30m + 69.99 = 200

           -69.99     -69.99

0.30m = 130. 01

130.01 / 0.30 = 433. 36...

but we're gonna round it to 433

so 433 miles

Answer:

[tex]Area = 34.2cm^2[/tex]

Step-by-step explanation:

Let the three sides be a, b and c respectively.

Such that:

[tex]a = 8[/tex]

[tex]b = 9[/tex]

[tex]c= 10[/tex]

Required

Determine the area

This is calculated as:

[tex]Area = \sqrt{s(s-a)(s-b)(s-c)[/tex]

Where

[tex]s = \frac{1}{2}(a + b + c)[/tex]

Substitute values for a, b and c

[tex]s = \frac{1}{2}(8 + 9 + 10)[/tex]

[tex]s = \frac{1}{2}(27)[/tex]

[tex]s = 13.5[/tex]

Substitute values for a, b, c and s in

[tex]Area = \sqrt{s(s-a)(s-b)(s-c)[/tex]

[tex]Area = \sqrt{13.5 * (13.5 - 8)* (13.5 - 9)* (13.5 - 10)[/tex]

[tex]Area = \sqrt{13.5 * 5.5* 4.5* 3.5[/tex]

[tex]Area = \sqrt{1169.4375[/tex]

[tex]Area = 34.2[/tex] -- Approximated

Your welcome

Step-by-step explanation:

-5x + 4y = 2

+ (9x - 4y = 6)

=> 4x = 8, x = 2.

Therefore -5(2) + 4y = 2, 4y = 12, y = 3.

The solution pair is (2,3).

Answer:

<ABC = 51°

Step-by-step explanation:

Given

<A = 2x -15°

<B = x - 5°

< C = 148°

Now

<A + <B = < C ( Exterior angle of a triangle is equal to the sum of two opposite interior angles)

2x -15° + x - 5° = 148°

3x - 20° = 148°

3x = 148° +20°

3x = 168°

x = 168° / 3

X = 56°

Now for Angle B

= 56° - 5°

= 51°

Step-by-step explanation:

Volume of a cylinder formula:

Let's find the height of the cylinder by multiplying 20 cm by 3/5.

The radius is 1/2 of the diameter, so:

Substitute 12 for h and 10 for r into the volume formula.

Simplify.

The volume of a cylinder, in terms of π, is V = 1200π.

it would be 1 right? Since 1x2 is 2 and so 2+4 would be 6, then 6-5 would be 1
