Known:

Every week Hannah's office recyles 2 kilograms of paper

1 week = 2 kg of paper

To find a rate at which the office recyles paper divide the unit of measurement (kg) by a unit of time (weeks)

So:

2 kg/ 1 week = 2 kg of paper recycled per week

We want to know how many weeks it will take to recycle 8 kg.

Think of it this way.

if you divide kg by kg/week the kg cancel out and you get the unit week.

So divided 8 kg by the rate we discovered (2 kg/week) and you shall get the answer 4 weeks.

Answer:

Rate is 2%

Step-by-step explanation:

Step one:

given data

Principal= $7500

Simple interest= $450

time=3 years.

Applying the simple interest formula which is

SI=PRT/100

Step two:

substitute we have

450=7500*R*3/100

cross multiply we have

45000=22500R

divide both sides by 22500

R=45000/22500

R=2%

Answer:

Speed is the rate of change in position of an object, regardless of direction of travel. Walk forward or backward at 2 meters per second, and your speed is just that: 2 m/s. Velocity is speed in the context of direction. Say you were walking backward again; your velocity is negative 2 m/s, although your speed is still positive.

Step-by-step explanation:

The given speed in yards per month will be 10,800 yd/mo.

Speed is the rate of change in position of an object, regardless of direction of travel.

Walk forward or backward at 2 meters per second, then speed is just that: 2 m/s.

Velocity is speed in the context of direction.

An object is moving at a speed of 9 inches per minute.

9 in/ min = (9 in/ min) x (1 yd / 36 in) x ( 60 min/ 1 h) x (24h / 1 d) x (30 d/ 1 mo )

9 in/ min = 10,800 yd/mo

Therefore, the given speed in yards per month will be 10,800 yd/mo.

Answer:

625

Step-by-step explanation:

with long division, you just need to remember these five steps, divide, multiply, subtract, bring it down, and repeat.

hope this helps :3

if it did pls mark brainliest

The number 2000 divided by 3.2, then the quotient is 625.

To perform long division with 2,000 divided by 3.2, follow these steps:

Step 1: Write down the division problem.

2,000 ÷ 3.2

Step 2: Convert the divisor to a whole number.

Since the divisor is a decimal, multiply both the dividend and divisor by a power of 10 to eliminate the decimal. In this case, multiply both numbers by 10 to get rid of the decimal point:

2,000 × 10 = 20,000

and

3.2 × 10 = 32.

Step 3: Divide the first digit of the dividend by the divisor.

In this case, the first digit of 20,000 is 2, and when divided by 32, the quotient is 0. Therefore, write down 0 as the first digit of the quotient.

Step 4: Multiply the quotient digit by the divisor and subtract from the dividend.

Multiply 0 by 32:

0 × 32 = 0

Subtract the result from the dividend:

20,000 - 0 = 20,000

Step 5: Bring down the next digit of the dividend.

Since we have no more digits in the dividend, stop here.

Step 6: Write down the final result.

The quotient is the result of the division:

2,000 ÷ 3.2 = 625

Therefore, when dividing 2,000 by 3.2 using long division, the quotient is 625.

Answer: (1)-8

Step-by-step explanation: −6r+18=k(x−15)

Step 1: Flip the equation.

kx−15k=−6r+18

Step 2: Factor out variable k.

k(x−15)=−6r+18

Step 3: Divide both sides by x-15.

k(x−15)/x-15 =

−6r+18/x-15

k= −6r+18/x-15= -8

Answer:

Parallel lines have the same slope, while perpendicular lines have completely opposite slopes. So a line has a slope of 2, a parallel line would have a slope of 2, and a perpendicular line would have a slope of -1/2. The easiest form to identify the slope is standard form because it shows the slope within the equation with out having to solve the equation or convert it into another form.
