Sides of the triangle are proportional.

(3.6 m)/(1.2 m) = h/(1.2 m + 2.8 m)

(4 m)(3.6/1.2) = h . . . . . multiply by 4 m

h = 12 m

The sum of two numbers is 30. Their difference is 12. Use substitution to solve a system of equations to solve for the two numbe

denpristay [2]

Answer:

9 and 21

Step-by-step explanation:

setting up the equation

let x and y represent the two numbers

this means that x + y = 30

x - y = 12

using substitution to solve

if x - y = 12, that can be rearranged to x = y + 12.

substitute x = y + 12 into x + y = 30

you get (y + 12) + y = 30

simplify

2y + 12 = 30

2y = 18

y = 9

plug this into the original equation x + y = 30. this would be

x + 9 = 30

x = 21

the numbers are 21 and 9.

P(S) = 5/8 P(T) = 1/8 If S and T are mutually exclusive events, find P(S or T),

Aleks04 [339]

Answer:

P(S ∪ T) = 3/4

Step-by-step explanation:

Given:

P(S) = 5/8
P(T) = 1/8

For mutually exclusive events S and T,

P(S ∪ T) = P(S) + P(T)

Therefore,

P(S ∪ T) = (5/8) + (1/8)

= 6/8

= 3/4
