**Answer:**

**height = 9.19 ft**

**Step-by-step explanation:**

The ladder is resting on a wall. The angle the ladder makes with the floor is 45°. The ladder is 13 ft. The illustration forms a right angle triangle.

The hypotenuse side of the right angle triangle is 13 ft . The opposite side of the right angle triangle is the unknown which is the height off the ground the top of the ladder. Therefore,

Using ratio

sin ∅ = opposite/hypotenuse

sin ∅ = opp/13

sin 45° = opp/13

cross multiply

13 sin 45 = opp

opp = 13 × 0.70710678118

opp = 9.19238815543

**height = 9.19 ft**

You can use the following base on your equation(y = 13 cos ∅)

The other angle will definitely be 45° since total angle in a triangle is 180°. 180 - 90 - 45 = 45°.

The adjacent side of the triangle will be the unknown side if we use cosine ratio.

cos ∅ = adjacent/hypotenuse

cos 45° = adjacent/13

cross multiply

From your equation you represented adjacent as y therefore,

y = 13 cos 45°

y = 13 × 0.70710678118

y = 9.19238815543

**y = 9.19 ft (which is the required height)**

B. 21 Bo; 23 Erica

C. 16 Bo; 28 Erica

D. 19 Bo; 25 Erica

Answer: D. 19 Bo; 25 Erica

Step-by-step explanation:

Let x represent the number of yoga classes that Bo teaches in a week.

Let y represent the number of yoga classes that Erica teaches in a week.

Between the two of them, they teach 44 yoga classes each week. This means that

x + y = 44 - - - - - - - - - - -1

If Erica teaches 13 fewer than twice as many as Bo, it means that

y = 2x - 13

Substituting y = 2x - 13 into equation 1, it becomes

x + 2x - 13 = 44

3x = 44 + 13 = 57

x = 57/3 = 19

y = 2x - 13 = 2 × 19 - 13

y = 25

**Answer:**

13 pages : 1/2 hour Multiply both sides by 2

26 pages : 1 hour ------>> 26 pages/hr

Flip over 26 pages/hr ----->>> hr / 26 pages = 1 hr / 26 pages

Split up the fraction: (1/26) hr / page

**Answer:**

26

**Step-by-step explanation:**

13 in 1/2 hour

13:1/2

26:1

Whales and dolphins are both mammals. So, because whales cannot breathe underwater but must come up to the ocean's surface to breathe, it is likely that dolphins must also swim to the surface to breathe air.

Argument A is :_______

a. strong

b. weak

Argument B:

Harry has always had an aptitude for history, geography, and social sciences, but he has always struggled with abstract concepts such as mathematics and physics. But Harry must take a college physics course to fulfill a general education requirement for his degree. Based on his academic track record, it is likely that Harry will be one of the top students in his college physics course.

Argument B is :_______

a. strong

b. weak

Argument C:

Out of a bag of 100 marbles, 97 red marbles were drawn in a row at random. Based on this sample, it is probably the case that the remaining 3 marbles are also red.

Argument C is :_______

a. strong

b. weak

Argument D:

The label on the side of a certain soda can indicates that the can was manufactured by Ball Corporation in their plant in Fairfield, California. Based on the information on the can's label, it is unlikely that the can was manufactured by any company other than Ball Corporation.

Argument D is :_______

a. strong

b. weak

**Answer:**

Argument A: a. strong

Argument B: b. weak

Argument C: a. strong

Argument D: a. Strong

**Step-by-step explanation:**

Dolphins and whales are mammals. They do not have gills like other fishes for breathing. They have to come to surface of water to breathe. The whales can store oxygen and can stay alive without breathing for more than an hour while dolphins can stay without breathing for few minutes. Harry has struggles with physics and mathematics therefore he cannot be top scorer in this subject based on his past track record.

The least precise measurement of the perimeter of the window is 231.30

Step-by-step explanation:

The least price measurement mean a value with the least number of significant figures.calculate the perimeter in this case as;

Perimeter of a rectangle = 2(l+w) where l is the length and w is the width

Perimeter= 2(81.47 + 34.2)

Perimeter=2(115.67)

Perimeter=231.34

Perimeter=231.30(4 significant figures)

Step-by-step explanation:

The least price measurement mean a value with the least number of significant figures.calculate the perimeter in this case as;
