First, we must identify the type of logarithm rule presented; the provided information pertains to the logarithm product rule, which states that the logarithm of a product can be expressed as the sum of the logarithms of the individual bases.

By:

= log (1.37 x 10⁹) = log (1.37) + log (10⁹)

= log (1.37) + 9

= 9 + log (1.37)

At this moment, since 1.37 lies between 1 and 10, its logarithm will be within the range of 0 and 1. As such, the value of log (1.37 x 10⁹) is between 9 and 10 because using scientific notation requires a number between 1 and 10 multiplied by 10 raised to some exponent. This exponent indicates the integer portion of the logarithm.

Square T was translated by the rule (x + 2, y + 2) and then dilated from the origin by a scale factor of 3 to create square T″.
AnnZ [12381]

Answer: OPTION C.

Step-by-step explanation:

It is essential to consider the following:

Dilation:

  • A transformation where the image retains the same shape as the original but differs in size.
  • Dilation maintains the order of points.
  •  Measurements of angles remain unchanged.

Translation:

  • A transformation that keeps the image identical in size and shape to the original.
  • Translation preserves the ordering of points.
  • The angle measurements do not change.

Consequently, since Square T underwent translation followed by dilation to form Square T'', we conclude that the rationale explaining why they are similar is:

Translations and dilations maintain the order of points; thereby, the corresponding sides of squares T and T″ are proportional.

Assume that the playbook contains 9 passing plays and 15 running plays. The coach randomly selects 8 plays from the playbook. Wh
Zina [12379]
<span>The outcome = probability of choosing exactly 2, 3, 4, or 5 passing plays. The probability of selecting exactly two passing plays is given by: (8C2)*(9*8)* (15*14*13*12*11*10) /(26*28*.....19) where: 8C2 represents the combinations of choosing two from 8 and probability that the first passing play is selected = 9/26 probability that the second passing play is chosen = 10/25, and so forth you can similarly calculate the other three scenarios and sum them to find the total probability.</span>

Hospital sends an invoice to a patient. The patient schedules a payment plan in which she makes an initial payment of $1,451 the
lawyer [12517]
In the first month, she made a payment of $1451

In the second month, she paid one-third of that, which amounts to:
1451/3 = 483.66

For the third month, she pays one-third of 483.66 as indicated, meaning she takes one-third of the prior month's payment.

483.66/3 = 161.22

In the fourth month, her payment was

161.22/3 = 53.74

Altogether, her total payments amounted to:

$2149.62 - B.

Hope this information is helpful:)

Tim was given a large bag of sweets and ate one third of the sweets before stopping as he was feeling sick. The next day he ate
Leona [12618]

Answer: Initially, he had 27 sweets.

Step-by-step explanation: The most logical approach is to work backwards from what remained after the third day to the start of the first day.

On the third day, he consumed one-third of his sweets and was left with 8. If we let the total sweets on day three be denoted as a, then one-third of a equals what he ate and the two-thirds left equals 8, giving us:

8/a = 2/3

By cross-multiplying, we find:

8 x 3 = 2a

Therefore, 24 = 2a

This leads to a = 12.

Let the sweets on day two be represented as b. If he consumed one-third of b and was left with 12, we have the same structure; hence:

12/b = 2/3

Cross-multiplying gives:

12 x 3 = 2b

So, 36 = 2b, leading to b = 18.

Denote the number of sweets on day one as x. If one-third of x was eaten and 18 remained, we can set up the equation:

18/x = 2/3

Again, cross-multiplying results in:

18 x 3 = 2x

Which simplifies to 54 = 2x, yielding x = 27.

Thus, Tim received 27 sweets at the start.
