Solve the equation please​

Mathematics
1 answer:
Oksi-84 [34.3K]3 years ago
6 0

Answer:

Step-by-step explanation:

The given equation is expressed as

√2x + 9 - √x + 4 = 0

Adding √x + 4 to the left hand side and the right hand side of equation, it becomes

√2x + 9 = √x + 4

Squaring the left hand side and the right hand side of equation, it becomes

2x + 9 = x + 4

Subtracting x from the left hand side and the right hand side of equation, it becomes

2x - x + 9 = 4

x + 9 = 4

Subtracting 9 from the left hand side and the right hand side of equation, it becomes

x = 4 - 9

x = - 5

Two pumps connected in parallel fail independently of one another on any given day. The probability that only the older pump wil
Bogdan [553]

Answer : Probability that the pumping system will fail on any given day = 0.005

Explanation:

Probability that only older pump fail = P(A) = 0.10

Probability that only newer pump fail = P(B) = 0.05

Since they are independent events ,

then the conditions will be

P(A∩B) = P(A). P(B)

             = 0.10 ×0.05

             =  0.005

Hence, the probability will fail on any given day = 0.005

kifflom [539]

Answer:

1,670 feet

Step-by-step explanation:

Given that the scale is

1/4 inches : 167 feet, i.e

1/4 inches (model) --> equivalent to 167 feet (actual)   (multiply both sides by 4)

1 inch (model) --> equivalent to 167 x 4 = 668 feet (actual)

2.5 inch (model)--> equivalent to 668 x 2.5 = 1,670 feet
