Joan is 4 feet 2 inches tall. There are 2.54 centimeters in 1 inch. What is Joan's height in centimeters? *(HINT: CHANGE HIS HEI
Hoochie [10]

Answer:Joan's height is 127 centimetres

Step-by-step explanation:

 Step 1

Joan  is  4 feet 2 inches tall and we want to change to centimeters .

we first change her height to inches

1 Foot = 12 Inches

Therefore  4 Feet = 4 x 12 = 48 inches

Total height in inches =48 inches + 2 Inches = 50 inches

Step 2 --Now, we have gotten her height in inches, we can now  change  to centimetres.

We have that

 1  inch =2.54 centimeters

50inches = 50 x 2.54 cm

=127 centmeters.

Joan's height is 127 centimetres

How many models of 100 do you need to model 3200 explain ​
rusak2 [61]

32 models need to make model of 3200.

Given that a 1 model contain 100.

Two series of numbers, usually empirical data, that are proportional or proportional if their respective elements are in constant proportion, called the scaling factor or the rate constant.

One model has 100 elements.

Now, we have to find how many model contains 3200 elements.

So, 1 model=100 elements

n model =3200 elements

We will write this in proportion as

1/n=100/3200

Applying the cross multiply, we get

3200×1=n×100

Divide both sides with 100, we get

3200/100=100n/100

3200/100=n

32=n

Hence, the  32 models contain 3200 elements when one contain 100 elements.
