Answer:

7.  y=42

8. y=58

If we could call on discord, zoom or anything like that i could easily explain. To type out the whole process would take all night

Step-by-step explanation:

Answer:

7.  42 degrees

8. 58 degrees

Step-by-step explanation:

Question 7

The three angles on the bottom line add up to 180.

65 + 31 + 2y = 180

2y = 84

So y = 42

Question 8

Let's start with the triangle with the 27 degree angle.

We have 27 + 90 + z = 180 (z is the top right angle)

z = 63 (which is also the bottom left angle of the triangle with the 32 degree angle).

63 + 32 + x = 180

x = 85 degrees

Now we look at the bottom polygon with the y degree angle we're trying to find.

We have one angle opposite x and another opposite z.

The angle opposite x + x = 180

The angle opposite x + 85 = 180

The angle opposite x = 95

The angle opposite z + z = 180

The angle opposite z + 63 = 180

The angle opposite z = 117

The sum of the interior angles of a polygon equals the number of sides less 2 * 180.  We have four sides, so the interior angles add up to 360.

90 + 95 + 117 + y = 360

Therefore y = 58 degrees

Dr. Cohn is testing how long it takes for a person's body to process a new medicine. She observes that the medicine is used by the body at a constant rate. For her latest test, Dr. Cohn starts with 15 milligrams of the medicine and notes that 12.6 milligrams remain unused after 1 hour. Which equation could Dr. Cohn use to solve for p, the percentage of the medicine that is used in 1 hour? A. p100=12.615 B. p100=2.415 C. p15=1002.4 D. p15=10012.6

Answers

Answer:

the options were not copied correctly, option B could be correct but it is missing the division signs:

B. p / 100 = 2.4 / 15

the percentage of medicine used in 1 hour:

p / 100 = (15 - 12.6) / 15 = 2.4 / 15

p / 100 = 0.16

p = 0.16 x 100 = 16%

another option could be C but it would be missing the multiplication signs:

C. p x 15 = 100 x 2.4

p x 15 = 240

p = 240 / 15 = 16%

Which correctly explains how to estimate 55 percent of 64? A. Round 55 percent to 40 percent and 64 to 60. Think of 40 percent as 1/4 so 1/4 of 60 is 15 B. Round 55 percent to 60 percent and 64 to 70. Think of 60 percent as 1/3 so 1/3 of 70 is 23.3 C. Round 55 percent to 50 percent and 64 and 70. Think of 50 percent as 1/5 so 1/5 of 60 is 12 or D. Round 55 percent to 50 percent and 64 to 60. Think of 50 percent as 1/2 so 1/2 of 60 is 30

Answers

B. It’s definitely B

Answer: Choice D

Round 55 percent to 50 percent and 64 to 60. Think of 50 percent as 1/2 so 1/2 of 60 is 30.

===================================================

Explanation:

There are many ways to estimate, but this is probably the easiest since 1/2 = 0.50 = 50%, and taking half of something is fairly straightforward and quick.

Taking half of 60 is like taking half of 6, except we stick at 0 at the end.

Half of 6 is 3

Half of 60 is 30

The estimate of 55% of 64 is 30

The actual value is

55% of 64 = 0.55*64 = 35.2

which isn't too far off.

-------------------------

Extra info:

Choice A is false because 40% is not equal to 1/4. Instead 1/4 = 0.25 = 25%Choice B is false because 1/3 = 0.333 = 33.3% approximately, so 1/3 is not equal to 60%Choice C is false because 1/5 = 0.20 = 20% and not 50%

Oceanside Bike Rental Shop charges 12 dollars plus 6 dollars an hour for renting a bike. Write an expression for the cost of renting bikes for x hours.

Answers

Answer:

[tex]y = 12 + 6x[/tex]

Step-by-step explanation:

Given

[tex]Base\ Amount = 12[/tex]

[tex]Additional = 6[/tex] per hour

Required

Determine the expression for the cost in x hours

Represent the cost with y

y is calculated using the following expression

[tex]y = Base\ Amount + Additional * x[/tex]

Where x represent the number of hours.

Substitute values for the base amount of bike and the additional cost per hour

[tex]y = 12 + 6 * x[/tex]

[tex]y = 12 + 6x[/tex]

So, the expression to determine the cost of bike in x hours is: [tex]y = 12 + 6x[/tex]

An architect designs two similar triangular patios. The first patio has angle measures of (x + 10)°, (y + 15)°, and 70°. The second patio has angle measures of (x + 20)°, 50°, and 60°. Find the values of x and y.

Answers

Given:

An architect designs two similar triangular patios.

The first patio has angle measures of (x + 10)°, (y + 15)°, and 70°.

The second patio has angle measures of (x + 20)°, 50°, and 60°.

To find:

The values of x and y.

Solution:

We know that, corresponding angles of similar triangles are equal. So, the value of (x + 20)° must be 70°.

[tex]x+20=70[/tex]

[tex]x=70-20[/tex]

[tex]x=50[/tex]

The value of x is 50.

Now,

[tex](x+10)^\circ=(50+10)^\circ[/tex]

[tex](x+10)^\circ=(60)^\circ[/tex]

So, remaining angles must be equal, i.e., (y + 15)° and 50° are equal.

[tex]y+15=50[/tex]

[tex]y=50-15[/tex]

[tex]y=35[/tex]

Therefore, the values of x and y are 50 and 35 respectively.

The values of x and y are 50 and 35 respectively.

The corresponding angles of similar triangles are equal. Therefore,

The first patio angles are:

x + 10

y + 15

70°

The second patio angles are ;

x + 20

50°

60°

Therefore,

x + 20 = 70

x = 70 - 20

x = 50

y + 15 = 50

y = 50 - 15

y = 35
