Six copies of the sum of nine-fifths and three

Answers

Answer 1
Answer: i think copies is a multiplication and sum is to add together so 
6x(9/5+3)
9/5 is 1 whole and 4/5. 1 whole plus 3 wholes is 4 Wholes so it is 4 wholes and 4/5 which is 24/5.
6x24/5 is (6x24 is 144) so its 144/5 so its 28 wholes and 4/5.

Answers


Let's see -

There are 2 ways we can do this -

Way 1) You can multiply each of your answers by 8 and see which one equals 32.

8 × 3 = 24   This would not be correct.

8 × 24 = 192   Wow! This is way bigger than 32!

8 × 4 = 32   Now we don't have to try multiplying 8 by 25 since we have our answer -

x = 4

______________________________________________________

Way 2) This way is so much faster, but you can use any way you'd like -

This was is just dividing 8 by 32 and seeing what you get.

8 ÷ 32 = 4

x = 4

↑   ↑   ↑  I hope each way will help you! :D

The answer to your question is x=8 because 8 divided 32 is 4

The population of a city is expected to increase by 7.5% next year. If p represents the current population, write an expression that represents the expected population next year?

Answers

Answer:  1.75p


Step-by-step explanation:

Let 'p' represents the current population.

The increase in the population of the city =7.5%

Therefore,  the expected population next year= Current population+75% of the current population

=p+75\%\ of\ p\ \n=p+0.75p....\text{[convert percent into decimal]}\n=p(1+0.75).........\text{[take p as common outside]}\n=p(1.75)=1.75p

Hence, the expected population next year= 1.75p

p+7.5\%p=p+0.075p=\boxed{1.075p}

slope = -3/7 what is the equation?

Answers

Answer:

y = -(3/7)x + 2

Step-by-step explanation:

(see attached)

recall that the slope-intercept form of a linear equation is

y = mx + b

where m = slope = given as -(3/7)

and b = y-intercept = 2

substituting these values into the eqation:

y = mx + b

y = -(3/7)x + 2

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:

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

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}}.
