Find the missing side b. A. 16.1 B. 19.7 C. - 1

Answers

Answer 1
Answer:

Answer: A . 16.1

Step-by-step explanation:

In the figure we have a right triangle in which one of the leg's length is missing.

  • Pythagoras theorem of right triangles says that the square of hypotenuse is the sum of the squares of the two legs.

For the given triangle , we have(18)^2=b^2+8^2

i.e. \Rightarrow\ 324=b^2+64

i.e. \Rightarrow\ b^2=324-64

i.e. \Rightarrow\ b^2=260

i.e. \Rightarrow\ b=√(260)=16.1245154966approx16.1

Hence, the missing side = 16.1 units
Answer 2
Answer: 16.1. Solve by using the Pythagorean Theorm. b squared+8 squared= 18 squared. b squared+64=324. Subtract 64 from both sides to get b squared=260. Square root 260 to get 16.1

Answers

Set of ordered pairs (x, y) could represent a linear function

B= {(-1,2), (2, 1), (5,0), (8, -1)}

Option B is correct

Linear Function

Linear function is a function whose graph is a straight line .

Slope

Slope of a line tells us how steep the line is . Slope of a line is same at all the points.

Slope formula is (y_2-y_1)/(x_2-x_1)

Lets find out slope of any two points in each option

A = {(-6,3), (-3,0), (0, -3), (3,-5)}

(0-3)/(-3+6) =-1\n(-5+3)/(3-0) =-(2)/(3) \n

Slopes are not same

Lets check the second option

B={(-1,2), (2, 1), (5,0), (8, -1)}

(1-2)/(2+1) =(-1)/(3) \n(0-1)/(5-2) =(-1)/(3) \n(-1-0)/(8-5) =(-1)/(3) \n

The slope of any two points are equal .

slope are same . So it represents a linear function .

C = {(-4,-7), (-1, -3), (2.0), (5,3)}

slope =(-3+7)/(-1+4)=(4)/(3) \nslope =(0+3)/(2+1)=(3)/(3)=1

Slopes are not same . So it is not a linear function

D = {(-5, -8), (-2,-4), (1,1), (4,6)}

slope = (-4+8)/(-2+5)= (4)/(3) \nSlope = (1+4)/(1+2)= (5)/(3) \n\nslope = (6-1)/(4-1)= (5)/(3) \n

Slopes are not same . so it is not a linear function .

Option B is correct.

Leon left a 15% tip for a meal. the total cost of the meal including the tip was $41.40. What was the cost the meal before the tip was added?

Answers

% * whole = part
0.15 * 41.40 = 6.21
6.21 is the tip.
41.40 - 6.21 = 35.19
The cost is $35.19

I have 4 factors three of my factors are 1,2,10 what is my fourth factor

Answers

5. Because 1*10=10 and 2*5=10

Answer

The fourth factor is 5

Explanation

It is given that there are only four factors. Three of them are 1, 2, 10

Here 10 is a factor, so we know that , if 10 is a factor of a number,

the we can write, 10 = 5 x 2, it implies that 5 and 2 are the factors of that number. Here 2 is given. Therefore the fourth factor is 5

The four factors are 1,2,5 and 10
