for the second question the options are: 71034, 71034000, 710.34 and 7013.4

Answers

Answer:

[tex]0.0005[/tex] [tex]= 5 * 10^{-4[/tex]

[tex]7.1034 * 10^3 = 7103.4[/tex]

Step-by-step explanation:

Solving (a):

[tex]0.0005[/tex]

Standard form is represented as:

[tex]a * 10^n[/tex] where [tex]1 \le a \le 10[/tex]

Move the decimal point to 5 and count the number of times the decimal point is moved forward (forward represents negative).

So:

[tex]a = 5[/tex]

[tex]n = -4[/tex]

Hence:

[tex]0.0005[/tex] [tex]= 5 * 10^{-4[/tex]

Solving (b):

[tex]7.1034 * 10^3[/tex]

Express [tex]10^3[/tex] as [tex]1000[/tex]

This gives:

[tex]7.1034 * 10^3 = 7.1034 * 1000[/tex]

[tex]7.1034 * 10^3 = 7103.4[/tex]

Answer:

[tex]log \left( \frac{a^2\,\,b^4}{c\,\,d^3} \right)[/tex]

Step-by-step explanation:

We use the properties of logarithms to write this as a single logarithmic expression. First the exponent property:

  2 log(a) + 4 log(b) - log(c) - 3 log(d) =

= log(a^2) + log(b^4) - log(c) - log(d^3) =

and now the multiplication and division properties

= [tex]log \left( \frac{a^2\,\,b^4}{c\,\,d^3} \right)[/tex]

What is the final temperature?

Use the below equation. Round to the nearest whole number and do not use units in your final answer.

T2=V2 x T1V1

2) A 2.5L container of an unknown gas has a pressure of 300kPa. The container is squeezed and has a final volume of 2.0L.

What is the final pressure of the container?
Use the below equation. Round to the nearest whole number and do not use units.

P2 =P1V1/V2

3) Charles’ law is
V1T1=V2T2
A closed container has an initial temperature of 300K. The container volume is changed until the final volume is 2L and the final temperature is 425K.

Calculate the initial volume using the equation from Charles' Law.

Answers

Answer:

50 minutes

Step-by-step explanation:

15 / 3 = 5

5 x 10 = 50

Answer

50 minutes

Step-by-step explanation:

If Genny makes 3 bracelets in 15 minutes, she can make 9 bracelets in 45 minutes.

9/3 = 3

3 x 15 = 45 minutes

She needs to make one more bracelet. It takes 5 minutes to make one bracelet because: 15/3 = 5/1 (Five minutes = One bracelet)

45 mins + 5 mins = 50

Answers

Answer:

First one is d and second one is c

Step-by-step explanation:

(6x+7)(x-8)

(6x)(x) = 6x^2

(6x)(-8) = -48

(7)(x) = 7x

(7)(-8) = -56

Add all like terms together and you get choice d.

(w+3)(w-3)

(w)(w) = w^2

(w)(-3) = -3w

(3)(w) = 3w

(3)(-3) = -9

The new computer you want to buy costs $749.50. If you wait for it to go on sale for 17% off, what will the sale price be?

Answers

Answer:

$622.09

Step-by-step explanation:

The computer is $749.50 and if the computer is 17% off, it means that you only need to pay 83% of the original cost.

749.50/100 = 74.95

74.95*83 = $622.085

Since the thousandth is a 5, round up to $622.09

The sale price is $622.09

Circumference of the circle as 15 pi inches find the diameter

Answers

The formula for the circumference of the circle is 2πr or πd with r being the radius and d being the diameter. These 2 gives the same result because d=2r

Now because we know that the circumference is 15pi, we just need to reverse to find the diameter.

π*diameter=15*π

We can divide π from both sides.

diameter=15
