1 answer:

mote1985 [20]3 years ago

6 0

Answer:

The correct answer is B.

Step-by-step explanation:

Since Ralph and Patrick play on a basketball team, and Ralph played the whole first quarter and the first 4 minutes of the second quarter, while Patrick played the rest of the second quarter and all of the third quarter, and Ralph played the whole fourth quarter, given that each quarter is 10 minutes long, to determine how long did Patrick play during the second quarter, the following calculation must be performed, taking into account that the most important variable is the moment when Ralph is replaced by Patrick:

10 - 4 = X

6 = X

Therefore, Patrick played 6 minutes during the second quarter.

Find the solution of this system of equations.

elena-s [515]

Answer:

x = 9, y = 2

Step-by-step explanation:

Given the 2 equations

x + 10y = 29 → (1)

x - y = 7 → (2)

Subtracting (2) from (1) term by term will eliminate the term in x

(x - x) + (10y - (- y)) = (29 - 7), that is

11y = 22 ( divide both sides by 11 )

y = 2

Substitute y = 2 in either of the 2 equations

Substituting in (2)

x - 2 = 7 ( add 2 to both sides )

x = 9

Answer:

hypotenuse is not a rational number

Step-by-step explanation:

In a Right angled triangle , if a, b are the sides and h be the hypotenuse then relationship between them is given by

$h^{2}$ = $a^{2}$ + $b^{2}$

Here,

a= 4 in. [Given]

b = 6 in. [Given]

Thus ,

$h^{2}$ = $4^{2}$ + $6^{2}$

$h^{2}$ = 16 + 36

$h^{2}$ = 52.

h = $\sqrt{52}$ = 7.21110255......

Clearly, h is not a rational number
