A ladybugs length measures 2 cm express this measurement in meters. explain your thinking. include an Equation with an exponent in your explanation

Answers

Answer 1
Answer:

Answer:

Length of lady bug in meters is:

0.02

Step-by-step explanation:

A ladybugs length measures 2 cm.

We have to express this measurement in meters.

We know that 1 m=100 cm

1 cm= 1/100 m

      =0.01 m

2 cm=2×0.01 m

      =0.02 m

Hence, Length of lady bug in meters is:

0.02
Answer 2
Answer:

The measurement 2\text{ centimetre} in meters is \boxed{\bf 0.02\text{\bf\ metre}}.

Further explanation:

The centimetre and metre are the units of measurement to calculate the length of an object.

“Centi” is first introduced in metric system that means one hundredth of a unit.

Therefore, 1 meter is 100\text{ cm} or we can say a centimetre is one-hundredth of a meter.

It can be mathematically expressed as follows:

\boxed{1\text{ m}\rightarrow 100\text{ cm}}

Procedure used:

Conversion from centimetre to metre.

1) First divide the unit (cm) by 100.

2) Now represent the resultant fraction into decimal form by moving the decimal two times to the left.

Given:

The length of ladybug is 2\text{ cm}.

Calculation:

Step 1:

The length of ladybug is 2\text{ cm}.

Use the above procedure to convert 2\text{ cm} into meters.

First divide the number 2 by 100.

\boxed{2\text{ cm}=(2)/(100)\text{ m}}  

Step 2:

Now follow the second step of the procedure.

The first digit on the right of decimal known as tenths or can say (1)/(100).

The second digit on the right of decimal known as hundredth or can say (1)/(100).

The resultant fraction (2)/(100) can be convert into decimal form as follows:

\boxed{(2)/(100)=0.02}

Here, we shifted the decimal two times to the left in the digit 2.

Therefore, the unit of 2\text{ cm} in meters is 0.02\text{ m}.    

Thus,  the measurement 2\text{ centimetre} in meters is \boxed{\bf 0.02\text{\bf\ metre}}.

3. Matt bought 12 packages of hot dogs and hamburgers for a barbecue. Let x represent the number of packages of hot dogs, which cost $2.75 each. Let y represent the number of packages of hamburgers, which cost $3.20 each. Matt spent a total of $35.25. Write and solve a system of equations that can be used to represent the amount of hot dogs and hamburger packages Matt bought. Are there any constraints on your variables? Is the solution viable or non-viable?

Answers

Answer:

Matt bought 7 packages of hot dogs and 5 packages of hamburger.

Step-by-step explanation:

We are given the following in the question

Let x represent the number of packages of hot dogs.

Cost of one packet of hot dog = $2.75

Let y represent the number of packages of hamburgers

Cost of one packet of hamburgers = $3.20

Then, we can write the following equations:

x + y = 12\n2.75x + 3.2y = 35.25

Solving the two equations,

2.75x + 2.75y = 33\n2.75x + 3.2y = 35.25\n\Rightarrow 0.45y = 2.25\ny = 5\nx = 7

Thus, Matt bought 7 packages of hot dogs and 5 packages of hamburger.

The solution is viable.

Constraints to the system of equation:

x,y \geq 0 \nx + y = 12\n2.75x + 3.2y = 35.25

What is the least common multiple (LCM) of 5 and 7?

Answers

Answer:

35

Step-by-step explanation:

Express each number in terms of its prime factors

5 = 5 and 7 = 7

Then multiply each factor the greatest number of times it occurs in either number.

Both factors occur only once, thus

LCM = 5 × 7 = 35

Answer: 35.

7: 7, 14, 21, 28,35

5: 5, 10, 15,20, 25, 30, 35

Bradley completed 3/5 of his homework. What percent of his homework does he still need to complete?

Answers

5/5 would= 1 or completed, so since 3/5 is already completed the fraction would be 2/5 then to change 2/5 into a percent you make it into a decimal 1st
divide 2 by 5 and you get 0.4 . Then move the decimal point to the right twice and end up with 40 so 40% is your answer :) Hope this helped
