Answer:

None (x=∅)

Step-by-step explanation:

5(x - 3) + 6 = 5x - 10

5x-15+6 = 5x-10

-15+6+10=5x-5x

1 = 0

x = ∅

24 minutes

Step-by-step explanation:

figure out how much time he spent in total from the times given which is an hour and 42 minutes

subtract 31 minutes to account for science

then add 16 to 31 which gives you 47 then subtract that from the time still left

Then the time left after subtracting 47 and 31 gives you 24 minutes which is how much tyler spent on reading

Using exponential functions, it is found that:

a) Since the <u>amount of caffeine will be less than 50 mg</u>, the patient will be ready for the blood test by 6 a.m.

b) The patient could have ingest 231 milligrams of caffeine.

A decaying <em>exponential function</em> is modeled by:

A(t) = A(0)(1 - r)^t

In which:

  • A(0) is the initial value.
  • r is the decay rate, as a decimal.

In this problem:

  • Caffeine metabolize at a rate of 13% per hour, hence r = 0.13.

Then:

A(t) = A(0)(1 - r)^t

A(t) = A(0)(1 - 0.13)^t

A(t) = A(0)(0.87)^t

Item a:

The coffee cup contains 150 milligrams of caffeine, hence A(0) = 150.

At 6 a.m., it is 8 hours after drinking the coffee, hence we have to find A(8).

A(t) = A(0)(0.87)^t

A(8) = 150(0.87)^8

A(8) = 49.2

Since the <u>amount of caffeine will be less than 50 mg</u>, the patient will be ready for the blood test by 6 a.m.

Item b:

This A(0), considering <u>A(11) = 50</u>, hence:

50 = A(0)(0.87)^{11}

A(0) = \frac{50}{(0.87)^{11}}

A(0) = 231

The patient could have ingest 231 milligrams of caffeine.

55) A dilation of scale factor of 4 will produce a congruent figure<br>True or False​
vivado [14]

Answer:

False

Step-by-step explanation:

When a figure is dilated by a scale factor of 4, the new figure produced will be 4 times the size of the original figure. This means that, the size would change while the shape remains the same as the original figure.

Congruent figures must have the same shape and size.

Therefore, the figure produced when a dilation of scale factor of 4 is done is not a congruent figure. Rather, it is a similar figure.

So, get statement is FALSE.
