Jet001 [13]

Answer:

Teresa should build 7.5 inches model.

Step-by-step explanation:

Consider the provided information.

Teresa is building a scale model of the JP Morgan chase Tower in Houston.

Her scale model, 1.5 inches represents 61 meters.

The actual building is 305 meters tall,

First find how many 61's are there in 305.

For this divide 305 by 61.

\frac{305}{61}= 5

Actual building is 5 times taller than 61. Thus the model should be 5 times taller than 1.5.

multiply 1.5 with 5 gives us:

1.5\times 5=7.5

Hence, Teresa should build 7.5 inches model.

(Will give 1,000 points!) Look at the two 3s in this number:
dusya [7]

The only true statement is <em>"the orange 3 on the right is 1/10 of the value of the blue 3 on the left"</em>

<em />

This question bothers on place values.

<em />

Given the decimal value 89.033, the place value of the blue 3 on the left is the hundredth place (1/100) while the place value of the orange 3 is in the thousandth place(1/1000).

We need to<u> check which of the statement is correct. </u>

For the first option, the blue 3 on the left is 300 times the value of the orange 3 on the right;

  • 1/100 = 300(1/1000)
  • 1/100 = 3/10

Since 0.01≠0.3, hence the first option is wrong

For the second option, the blue 3 on the left is 100 times the value of the orange 3 on the right;

  • 1/100 = 100(1/1000)
  • 1/100 = 1/10

0.01≠0.1, hence the second option is wrong.

The blue 3 on the left is equivalent to the orange 3 on the right is also wrong since they are positioned in a different place

The orange 3 on the right is 1/10 of the value of the blue 3 on the left, is expressed as;

  • 1/1000 = 1/10(1/100)
  • 0.001 = 0.001

Hence the only true statement is <em>"the orange 3 on the right is 1/10 of the value of the blue 3 on the left"</em>
