198 cents. Let current price of bread be x cents. 9(x-44) = 7x, 9x - 396= 7x, 2x=396, or x = 198.

Answer:

198 cents or 1.98 dollars.

Step-by-step explanation:

Let x be the current price of the bread in cents,

So, the price of 7 bread = 7x cents,

If the current price of bread dropped by 44 cents,

New price of each bread = x - 44

So, the price of 9 bread = 9(x - 44)

According to the question,

7x = 9(x - 44)

7x = 9x - 396

7x - 9x = -396

-2x = -396

⇒ x = 198

Hence, the current cost of bread is 198 cents or 1.98 dollars.

Find the length of the unknown side.<br> 25 cm<br> 15 cm
AleksandrR [38]

Answer:

b = 20 cm.

Step-by-step explanation:

<u>Define and explain:</u>

This is a right triangle, so the Pythagorean Theorem applies.

The Pythagorean Theorem states that the sum of the squared legs will equal the squared length of the hypotenuse.

The legs of a triangle are the sides that form the right angle.

The hypotenuse is the longest side; the hypotenuse is always diagonal from the small square indicating a right angle.

<u>Solve:</u>

a^2+b^2=c^2

a,b-legs

c-hypotenuse

15^2+b^2=25^2

225+b^2=625

625-225=400

b^2=400

b=20

<u>Conclude:</u>

Therefore, the length of the unknown side is 20 centimeters.

A test for syphilis gives a positive result with probability 0.98 when tested on a person who has the disease. The test gives a
mestny [16]

Answer:

The probability that an individual has the disease and has a positive test result is:

9.8%.

Step-by-step explanation:

Probability of a true positive result for a test of syphilis = 0.98 or 98%

Probability of a false negative result for a test of syphilis = 0.02 or 2% (100 - 98)

Probability of a true negative result for a test of syphilis = 0.9 or 90%

Probability of a false negative result for a test of syphilis = 0.1 or 10% (100 - 90)

Therefore, the probability that an individual has the disease and has a positive test result = 0.98 * 0.1 = 0.098 = 9.8%
