Answer:

6.7 to 26

Step-by-step explanation:

Answer:

the time taken for the element to remain 1 gram is 38,400,000 unit.

Step-by-step explanation:

Given;

initial mass, m = 5 g

half life, t = 16,000,000 unit

The time taken for the element to remain 1 gram is calculated as;

          mass remaining                                      time

             5 g                                                        0

             2.5 g                                                    16,000,000

             1.25 g                                                   32,000,000

            0.625 g                                                 48,000,000

Interpolate to obtain the time at 1 gram;

1.25 g ----------------------------------   32,000,000

1 g --------------------------------------------- x

0.625 g --------------------------------------- 48,000,000

[tex]\frac{1.25 - 1}{1.25 - 0.625} = \frac{32,000,000 - x}{32,000,000 - 48,000,000} \\\\\frac{0.25}{0.625} = \frac{32,000,000 - x}{-16,000,000} \\\\-4,000,000= 20,000,000 - 0.625x\\\\0.625x = 20,000,000 + 4,000,000\\\\0.625x = 24,000,000\\\\x = \frac{24,000,000}{0.625} \\\\x = 38,400,000[/tex]

Therefore, the time taken for the element to remain 1 gram is 38,400,000 unit.

Answer:

f = 1.1 Hz

Step-by-step explanation:

Given that,

The velocity of an ocean wave, v = 4.4 m/s

The distance  between the crest of each wave is 4 m.

We need to find the frequency of the waves.

The distance between the crest of a wave is called the wavelength of a wave.

The relation between the frequency, wavelength and the velocity of a wave is given by :

[tex]v=f\lambda\\\\f=\dfrac{v}{\lambda}\\\\f=\dfrac{4.4}{4}\\\\f=1.1\ Hz[/tex]

So, the frequency of the waves is 1.1 Hz.

Answer: 3.75 liters

Step-by-step explanation:

1 liter = 8m^2

area of the wall = l x b (wide x high)

= 10 x 3

= 30m^2

so, quantity of paint needed = 30/8 = 3.75 liters

Answer:

it is b

Step-by-step explanation:

Well 9 - 5 = 4

to figure out (7 x ?) - 7-?

First you have to figure out what ? is

Well if 9 - 5 = 4, then the ? is 4!!

So 7 x 4 =28 and 28 - 28 = 0

so your anwswer is:

(7 x 4) = (28 - 28) and the ?=4

Answer:

Jay started with $148.5 and Kay with $24.75.

Step-by-step explanation:

With the information provided you know that Jay had 6 times as much money as Kay wich can be expressed as:

J=6K, where

J is the money Jay had

K is the money Kay had

Also, you know that  Jay gave Kay $33 and Jay now has twice as much money as Kay, which would be:

J-33=2(K+33)

Now, you can replace J=6K in this equation and solve for K:

6K-33=2K+66

6K-2K=66+33

4K=66

K=24.75

Then, you can replace the value of K in J=6K:

J=6*24.75

J=148.5

According to this, the answer is that Jay started with $148.5 and Kay with $24.75.

Step-by-step explanation:

Answer:

12 sides and measure of each interior angle is 150...

Answer:

Step-by-step explanation:

Number of sides = 360°/30° = 12

Interior angle is the supplement of exterior angle = 180°-30° = 150°

Answer:

ADB=45

Step-by-step explanation:

we know that angles a, b, c, and d are right, or 90 degrees. We also know that the two lines in the center are bisectors, which cut a angle perfectly in half. we can now use this equation for thet:

90/2=<ADB

ADB=45

Step-by-step explanation:

[tex]\color{plum}\tt\bold{(a) \: 250}[/tex]

Money Jefferson needs to collect = $500

Selling price of each baked good = $2

Cost price of each baked good = 0.50

Number of baked goods Jefferson need to sell to meet his goal :

[tex] =\tt \frac{500}{2} \times 0.50[/tex]

[tex] =\tt 250 \times 0.50[/tex]

[tex]\color{plum} =\tt 125 \: baked \: goods[/tex]

Thus, Jefferson needs to sell 125 baked goods.

▪︎Therefore, the correct option is (a) 125.

Answer:

[tex]\frac{1}{1892}[/tex]

Step-by-step explanation:

There are two possibilities for each of 13 questions, true or false.  As a result, you have a [tex]\frac{1}{2}[/tex] chance of choosing either of the choices.  To find this, you would multiply the probability to the power of the number of cases, meaning [tex](\frac{1}{2^(13)})=\frac{1}{1892}[/tex].
