Triangle S R Q is shown. Angle S R Q is a right angle. An altitude is drawn from point R to point T on side S Q to form a right
juin [17]

Answer:

RT = 12 units

Step-by-step explanation:

From the figure attached,

ΔSRQ is right triangle.

m∠R = 90°

An altitude has been constructed from point T to side SQ.

m∠RTQ = 90°

By applying geometric mean theorem in triangle SRQ,

\frac{\text{RT}}{\text{ST}}=\frac{\text{TQ}}{\text{RT}}

\frac{x}{9}=\frac{16}{x}

x² = 16 × 9

x² = 144

x = √144

x = 12

Therefore, length of altitude RT is 12 units.

Solve the inequality for u.<br> .<br> Simplify your answer as much as possible.
Jet001 [13]

Answer:

u ≤ 4

Step-by-step explanation:

The given inequality

15 ≤ 39 - 6u

Subtract 39 from both sides, we get

15 - 39 ≤ 39 - 6u - 39

-24 ≤ -6u

Dividing both sides by -6, we get

4 ≥ u                      [Remember, when we divide by negative, the direction of    

                              the inequality changes]

Which is u ≤ 4.

Thank you.

Jack needs 22 pirates for every 2 pirate ships he manages
AysviL [449]

Answer:

55 pirates for 5 ships, 121 pirates for 11 ships

Step-by-step explanation:

for every 2 ships he needs 22 pirates, divide both by 2 and we see that for every ship he needs 11 pirates, also can write as 2x= 22 and divide both sides by 2, x=11 now that we know for every ship he needs 11 pirates we just multiply 11 times the amount of ships or 11x=y, 11 times 5 is 55 and 11 times 11 is 121
