Answers

Answer:

2.56

Step-by-step explanation:

Multiply by (1+6e^(-.7t))/1000:

2000/1000 = 1 +6e^(-0.07t)

1 = 6e^(-0.07t) . . . . . . . . . subtract 1

e^(0.07t) = 6 . . . . . . . . . . multiply by e^(0.07t)

0.07t = ln(6) . . . . . . . . . take the natural log

t = ln(6)/0.07 . . . . . . . divide by the coefficient of t

t ≈ 2.55966 ≈ 2.56

the force (F) needed to cause the acceleration (a) of an object of mass, m, is given by the equation, F = ma where m is the objects mass. if a 12-newton force causes the object to accelerate to 3 m/s2 , what is the object's mass? the unit for this mass is kg.

help me pls /ᐠ｡ꞈ｡ᐟ\

Answers

Answer: According to Newton s Second Law of Motion, also known as the Law of Force and Acceleration, a force upon an object causes it to accelerate according to the formula net force = mass x acceleration. So the acceleration of the object is directly proportional to the force and inversely proportional to the mass.

Step-by-step explanation:

If F = ma where m is the objects mass. if a 12-newton force causes the object to accelerate to 3 m/s2 , then the mass in kg of the objects is 4 kg

What is Force?

When a body tends to modify or change the state by an external cause, it is called Force.

Given:

F=ma

Where,

F = Force (N)

m = mass (kg)

a = acceleration (m/s²)

F = 12-Newton

m = 3 m/s²

a = ?

F = ma

12 = m × 3

12 = 3m

divide both sides by 3

m = 12/3

m = 4 kg

Therefore, the mass in kg of the objects is 4 kg

Answers

Three statements are as follows -

1. It is a straight line drawn with a straightedge and cuts across the lines.

2. Both drawn with the same compass width.

3. Corresponding parts of congruent triangles are congruent.

This construction works by using the fact that a transverse line drawn across two parallel lines creates pairs of equal corresponding angles. It uses this in reverse - by creating two equal corresponding angles, it can create the parallel lines.

This is how to construct a line parallel to a given line that passes through a given point with compass and straightedge or ruler. It is called the 'angle copy method' because it works by using the fact that a transverse line drawn across two parallel lines creates pairs of equal corresponding angles. It uses this in reverse - by creating two equal corresponding angles, it can create the parallel lines.

Serina and 2 friends go out for dinner. Their bill is $92.18. How much more would
they pay if they left a tip of 20% instead of a tip of 15%?
$9.22
$4.61
$6.91
$2.76

Answers

Answer:

$4.61

Step-by-step explanation:

To calculate a tip of 20%, you would perform the following:

$92.18 * 0.20 = $18.436

Similarly, for a tip of 15%:

$92.18 * 0.15 = $13.827

The difference would just be subtracting the two tip amounts from each other!

$18.436 - $13.827 = $4.609

Then you round to the nearest cent.

$4.609 ≈ $4.61

What is 317.466 ounces or 19.8 pounds

1kg in household measurement is equal to 35.274 ounces.

So, 35.274*9= 317.466 ounces

317.466/16= 19.8 pounds

Answer:

D) 19.8 lbs

Explanation:

1kg in household measurement is equal to 35.274 ounces. 35.274*9=317.466 ounces.

1kg is also equal to 2.205 lbs. 9*2.205=19.8416

9 kg is also equal to 9000 grams, but grams are not a part of the household measurement system

a) 9000 grams. b) 9000 ounces. c) 19.8 ounces. d) 19.8 pounds.

This leaves us with 19.8 lbs

Explain the steps for dividing decimals. Write three or four sentences.

Answers

Answer:

(assuming we're deciding decimals by decimals)

Dividing decimals is alot like regular decimal dividing. First, you must move the decimal places so it becomes a whole number. This makes it easier and less confusing as steps go on. Now we can divide regularly as we go on, making sure to put the amount of decimal spots we moved back in the answer.

Answer:

The first step is to make the divisor a whole number by multiplying it by a power of 10. When you multiply the divisor by a power of 10, you must multiply the dividend by the same power of 10. Then divide. Check your answer using estimation.
