Answer:

$1036

Step-by-step explanation:

His room is 8 x 9 = 72 feet. The cost of each square foot is $14.

So 72ft x $14 = $1036. So its going to cost him $1036.

i hope i helped :)

How long will it take for the 1.35-mg sample of 236Pu in Example 19.4 to decay to 0.100 mg? (The half-life of plutonium-236 is 2

dedylja [7]

Answer:

10.7 years

Step-by-step explanation:

The decay equation can be written as ...

remaining = initial × (1/2)^(t/(half-life))

Filling in the given values, we can solve for t.

0.100 = 1.35 × (1/2)^(t/2.86)

0.100/1.35 = (1/2)^(t/2.86) divide by 1.35

Taking logs transforms this to a linear equation:

log(0.100/1.35) = (t/2.86)log(1/2)

Since log(a/b) = -log(b/a), we can multiply both sides by -1 and simplify the logs a bit.

log(1.35/.1) = t·(log(2)/2.86)

2.86·log(13.5)/log(2) = t ≈ 10.7 . . . . years

The decay time is about 10.7 years.

Airida [17]

Answer:

-4+(-3)= -7. The dolphin is -7 feet below sea level

Step-by-step explanation:

Start at -4 on the number line. When you add a negative number to a negative number, you move left on the number line. Move 3 units to the left to land at -7. The dolphin is 7 feet below sea level.

The following is an incomplete paragraph proving that the opposite sides of parallelogram ABCD are congruent:

Semmy [17]

Answer: Triangles BCA and DAC are congruent according to the Angle-Side-Angle (ASA) Theorem.

Step-by-step explanation:

Given : ABCD is a parallelogram.

That is, AB ║ CD and AD ║BC

We have to prove that: AB≅CD and AD≅BC

Proof:

Construct diagonal AC in the parallelogram ABCD.

Since, AC ≅ AC ( reflexive)

∠ BAC ≅ ∠ DCA ( By the alternative interior angle theorem)

∠ BCA ≅ ∠ DAC ( By the alternative interior angle theorem)

⇒ Δ BCA ≅ Δ DAC ( By ASA congruence postulate )

⇒ AB≅CD as well as AD≅BC ( BY CPCTC )

Thus, the opposite side of the parallelogram are congruent.
