Answer:

for 13 its x=60 and for 14 its x=120

Step-by-step explanation:

for 13 its a equilateral triangle meaning all sides are the same so the answer x=60

for 14 its a obtuse isosceles triangle meaning it has 2 angles that are the same and 1 obtuse angle so the other angles would be 30 and 120. hope this helps :)

Answer:

a. x/y = 2 b) y/x +y =1/3 c) x-y/y= 1 d) y/x = 1/2

Step-by-step explanation:

Solve for

a) x/y

as we know x +y/y = 3

x+y= 3y

x= 3y-y

x= y(3-1)

x/y= 3-1

x/y = 2

b) y/x+y

as we know x +y/y = 3

x+y = 3y

1= 3y/x+y

1/3 = y/x+y

So y/x +y =1/3

C) x-y /y

as we know x +y/y = 3

x +y = 3y

subtracting 2y from both sides

x +y -2y = 3y- 2y

x-y = y

dividing both sides by y

x-y/y = y/y

x-y/y= 1

d) y/x

as we know x +y/y = 3

x +y = 3y

x= 3y- y

x= 2y

dividing both sides by x

x/x = 2y/2x

1 = 2 x (y/x)

1 / 2 = y/x

Or y/x = 1/2

Best of luck.

Salsk061 [2.6K]

Answer:

1,001 ways for them to decide.

Step-by-step explanation:

The order in which they will visit the countries is not important, so we use the combinations formula to solve this question.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

In this question:

10 countries from a set of 14. So

$C_{14,10} = \frac{14!}{10!(14-10)!} = 1001$

1,001 ways for them to decide.

% Increase = Increase/original number x 100
Let I represent increase

((58-32)/32) x 100 = I
58oz - 32oz = 26oz
26/32 x 100 = I
0.8125 x 100 = I
Increase = 81.25%
