What is the difference between intersecting and perpendicular lines? Can two lines exist that are not intersecting or parallel?

sertanlavr [38]

Intersecting lines are lines that meet at some point while perpendicular lines are intersecting lines that makes a right angle at the point of intersection.

Two line can either be intersecting or perpendicular. It is not possible to have two line that is neither intersecting or parallel.

(1 point) A fish tank initially contains 15 liters of pure water. Brine of constant, but unknown, concentration of salt is flowi

Drupady [299]

Answer:

a. $\dfrac{dx}{dt} = 6\frac{2}{3} \cdot c$

b. $x(t) = 6\frac{2}{3} \cdot c \cdot t$

c. $c = \dfrac{3}{8} \ g/L$

Step-by-step explanation:

a. The volume of water initially in the fish tank = 15 liters

The volume of brine added per minute = 5 liters per minute

The rate at which the mixture is drained = 5 liters per minute

The amount of salt in the fish tank after t minutes = x

Where the volume of water with x grams of salt = 15 liters

dx = (5·c - 5·c/3)×dt = 20/3·c = $6\frac{2}{3} \cdot c \cdot dt$

$\dfrac{dx}{dt} = 6\frac{2}{3} \cdot c$

b. The amount of salt, x after t minutes is given by the relation

$\dfrac{dx}{dt} = 6\frac{2}{3} \cdot c$

$dx = 6\frac{2}{3} \cdot c \cdot dt$

$x(t) = \int\limits \, dx = \int\limits \left ( 6\frac{2}{3} \cdot c \right) \cdot dt$

$x(t) = 6\frac{2}{3} \cdot c \cdot t$

c. Given that in 10 minutes, the amount of salt in the tank = 25 grams, and the volume is 15 liters, we have;

$x(10) = 25 \ grams(15 \ in \ liters) = 6\frac{2}{3} \times c \times 10$

$6\frac{2}{3} \times c =\dfrac{25 \ grams }{10}$

$c =\dfrac{25 \ g/L }{10 \times 6\frac{2}{3} } = \dfrac{25 \ g/L}{10 \times \dfrac{20}{3} } =\dfrac{3}{200} \times 25 \ g/L= \dfrac{75}{200} \ g/L = \dfrac{3}{8} \ g/L$

$c = \dfrac{3}{8} \ g/L$

A building with a cost of $1,800,000 has an estimated residual value of $125,000, has an estimated useful life of 40 years, and

nika2105 [10]

Answer:

$41,875

<u>Extra</u>

a. $17,250 [($780,000 – $90,000) ÷ 40]

b. $366,000 [$780,000 – ($17,250 × 24 yrs.)]

c. $29,600 [($366,000 – $70,000) ÷ 10 yrs.]

Step-by-step explanation:

Step 1: Determine the cost of the asset

$1,800,000$

Step 2: Subtract the estimated salvage value of the asset from the cost of the asset to get the total depreciable amount

$1,800,000 - 125,000$

Step 3: Determine the useful life of the asset

$40$

Step 4: Divide the sum of step (2) by the number arrived at in step (3) to get the annual depreciation amount

$$41,875$

100 POINT QUESTION<br> Which postulate or theorem can be used to prove △ABC ≅ △KLM?

Solnce55 [7]

Answer:

ASA congruence theorem

Step-by-step explanation:

Given two triangles ABC and KLM.

In ΔABC and ΔKLM,

m∠CBA = m∠MLK (given angle)

BC = LM (given side)

m∠CAB = m∠MKL (given angle)

Therefore, ΔABC ≅ ΔKLM (by ASA congruence theorem)

Hence by ASA congruence theorem ΔABC ≅ ΔKLM.

A=115+1/2(p+s) solve for s

bulgar [2K]

A = 115 + 1/2 (p + s)

you subtract 115 from both sides, and you get

A - 115 = 1/2 (p + s)

now you multiply by 2 on both sides, and you get

(A - 115) * 2 = p + s NOTE: I DISTRIBUTED 2 IN THE FOLLOWING EQUATION

now you subtract p on both sides to get s by itself and you get

2A - 230 - p = s

so the final answer is .......

$s=2A-230-p$
