Answer:

87°

Step-by-step explanation:

If a quadrilateral is inscribed in a circle, then opposite angles are supplementary. That means that z + 93 = 180 and z = 87°

A class of 24 students is planning a field trip to a science museum. A nonrefundable deposit of $50 is required for the day-long

erica [24]

Answer:

Option A , C ,D

Step-by-step explanation:

A nonrefundable deposit required for the day-long program = $50

Charge per person = $4.50

Let us suppose the number of students is s

So, Charge for s students = $4.50s

Let c denotes the total cost

So, total cost : $c=50+4.50s$

So, Option A is correct : The linear model is f(s) = 4.5s + 50.

Total cost : $c=50+4.50s$

We are given that total students are 24

Substitute s = 0

So, $c=50$

Substitute s = 24

$c=50+4.50(24)$

$c=158$

So, Option C and D is also correct.

C. The domain is {x| 0 ≤ x ≤ 24}

D .The range is {y| 50 ≤ y ≤ 158}

Refer the attached figure

The graph is discrete .

So, Option E is incorrect.

Answer:

1. B) 5.7

2. A) 12

3. A) 11.4

4. A) 5.7

5. A) 16.2

6. A) 11.2

7. No, they do not form a right triangle

8. Yes, they do form a right triangle

Step-by-step explanation:

Extra tip: The hypotenuse has to be less than both sides added together, but cannot be more than either of the sides alone.

16² + b² = 17²

256 + b² = 289

256 - 256 + b² = 289 - 256

b² = 33

√b² = √33

b = 5.74 or 5.7

16² + b² = 20²

256 + b² = 400

256 - 256 + b² = 400 - 256

b² = 144

√b² = √144

b = 12

7² + 9² = c²

49 + 81 = c²

130 = c²

√130 = √c²

11.40 or 11.4 = c

7² + b² = 9²

49 + b² = 81

49 - 49 + b² = 81 - 49

b² = 32

√b² = √32

b = 5.65 or 5.7

a² + 5² = 17²

a² + 25 = 289

a² + 25 - 25 = 289 - 25

a² = 264

√a² = √264

a = 16.24 or 16.2

10² + b² = 15²

100 + b² = 225

100 - 100 + b² = 225 - 100

b² = 125

√b² = √125

b = 11.18 or 11.2

15² + 8² = 16²

225 + 64 = 256

289 ≠ 256

5² + 12² = 13²

25 + 144 = 169

169 = 169

What is the percent of change from 800 to 40?

marusya05 [52]

Answer:

95%

Step-by-step explanation:

%Change from 800 to 40 = %Decrease

%Decrease = Old Value - New Value/Old Value × 100%

%Decrease = 800-40/800 × 100%

%Decrease = 760/800 × 100%

% Decrease = 95%(Answer)
