Answer:

To write 0,0045 in scientific notation, we will have to move the decimal point three point to right, which literally means multiplying by 1000=103 . Hence in scientific notation 0.0045=4.5×10−3 (note that as we have moved decimal three point to right we are multiplying by 10−3

Answer:

Step 1 should have been 27(6 + 30).

Step-by-step explanation:

Given that:

The evaluation of the expression 27(36) by using the distributive property as portrayed by Liz is as follows:

27 (36)

Step 1 = 27 (3+ 12)

Step 2 = 27(3) + 27(12)

step 3  = 81 + 324

Step 4 = 405

What was the first error that Liz made?

From the above first step, we will see that :

27(3+12) was given, which is wrong.

the right step that is supposed to be there is:

27(6 + 30).

so the calculation will be:

Step 1 = 27(6+30)

Step 2 = 27(6) + 27(30)

Step 3 = 162 + 810

Step 4 = 972

Step-by-step explanation:

4(s-3)-4=4+8(3)

=4+24

=28

4s-12-4=28

4s-16=28

4s=28+16

4s=44

s=44/4

s=11

Step-by-step explanation:

f(x) = 25 / (10x -20)

When 10x - 20 = 0, f(x) is undefined. Therefore x = 2 is not in the domain for f(x) to be a function.

Answer = 2.

Answer:

4800 ml

Step-by-step explanation:

If you have any questions about the way I solved it, don't hesitate to ask :)

Answer:

4.8 L

Step-by-step explanation:

6 hours = 6*60*60 seconds = 21600 seconds

10 mL - 45 seconds

x mL - 21600 seconds

x = (21600*10)/45=4800 mL

4800 mL = 4.8 L

Answer:

x = ± 8 using the square root property

Square root both sides to get x = ± 8.

Answer:

47

Step-by-step explanation:

46, 24,87, 64, 39, 50, 37, 48

First put the numbers in order from smallest to largest

24,  37,  39,46, 48,50,64,87

Then we notice that there are 8 numbers.  The median is the middle

24,  37,  39,46     , 48,50,64,87

The middle is between 46 and 48

Take the average of these numbers

(46+48)/2 = 94/2 = 47

The median is 47

Answer:

49

Step-by-step explanation:

Fairly simple, line up the numbers in order from lowest to highest. Then find the middle two terms. Since we have 8 terms, we take the two in the center, 50 and 48 and add them together, then divide by two to get your median.

Answer:

Step-by-step explanation:

We are asked for the number of hours spent at the studio, so it is reasonable to let the variable x stand for the number of hours.

The total cost is ...

  vase cost + hourly cost = total cost

where hourly cost = (# of hours)(cost per hour)

  10 + 8x = 46

  8x = 36 . . . . . . subtract 10

  x = 4.5 . . . . . . . divide by 8

4.5 hours were spent at the studio.

Answer: 15%

Step-by-step explanation:

From the question, we are informed that Mrs Anderson weighed 160 pounds earlier and two months later, she had dropped to 136 pounds. To. Calculate the percent of decrease in her weight goes thus:

We've to find her decrease in weight first. This will be:

= 160 pounds - 136 pounds

= 24 pounds

Percentage decrease will now be:

= Change in weight/Original weight × 100

= 24/160 × 100

= 0.15 × 100

= 15%

The percent of decrease in her weight is 15%.

How many customers are on payment plan B?

23 customers

How many of the customers on plan B text?

13 customers

What is the probability that a randomly selected customer who is on plan B uses the phone most often to text? Give the answer in fraction form.

13/23

Step-by-step explanation:

edg 2020

The probability that a randomly selected customer who is on plan B uses the phone most often to text is 13/23

Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

P(E) = Number of favorable outcomes / total number of outcomes

The customers are on payment plan B = 23 customers

The customers on plan B text = 13 customers

The probability that a randomly selected customer who is on plan B uses the phone most often to text

= 13/23

Step-by-step explanation:

Answer:

On the horizontal axis

Step-by-step explanation:

The complex number is represented by the complex plane or z-plane which is the representation geometrically of the real (number) axis and the imaginary (number) axis

When plotting complex numbers, the real part of the complex number is always plotted on the horizontal axis while the imaginary part is plotted on the vertical axis

The complex plane concept facilitates the description of complex numbers geometrically.

The error in this congruence statement is that we don't know if these are actually congruent.

Saying that the triangles "look the same" simply isn't enough. We do know that all three angles are the same, but the AAA (Angle Angle Angle) postulate only works for similar triangles.

Additionally, even if they were congruent, it would still be triangle ABC ≅ triangle FED, not triangle DEF.
