<u>Answer:</u>

0.8 meters

<u>Step-by-step explanation:</u>

We know that One Shell Square is the tallest building in New Orleans with a height of about 212 meters and Marlie is creating a scale model of this building, using the scale 250 meters : 1 meter.

So to find the height of the scale model, we can simply use the ratio method.

\frac{212 m}{250m} =\frac{x}{1}

x=\frac{212}{250} = 0.848

Therefore, the height of the scale model to the nearest tenth of a meter will be 0.8 meters.

For the first one: i don't know...i think it can't be done.
for the second one, it is : 4 × (2 + 3) - 1 = 19
for the third one, it is 4 + ((3² +1) ÷ 5) = 6
for the fourth one, it is : (3 + 2) × 6 - 3 = 27
for the fifth one, it is : 7 + 4 - (9 ÷ 3) = 8
for the sixth one, it is : (6 ÷ 2) + (4 × 2) = 11
for the seventh one, it is : (3 + 1)² ÷ 4 = 4
for the eight one, it is : (12 + 20) ÷ 4² = 2
for the ninth one, it is :  7 + (7 - 18 ÷ 6)² = 23

What percentage is 142-58
Misha Larkins [42]

SOLUTION:

Step 1 :

In this question, we are meant to find what percent of 142 is 58.

Step 2 :

We make the assumption that 142 is 100 % since it is our output value.

Step 3:

We next represent the value we see with x.

Step 4 :

From step 2, it follows that 100 % = 142.

Step 5 :

In the same vein, x % = 58.

Step 6 :

This gives us a pair of simple equations:

\begin{gathered} 100\text{ \% = 142 ---- equ 1} \\ x\text{ \% = 58 }\ldots\ldots\ldots\ldots\text{ equ 2} \end{gathered}

Step 7 :

By simply dividing equation 1 by equation 2 and

taking note of the fact that the Left-Hand Side of both equations have the same unit ( % ), we have that :

\frac{100\text{ \%}}{x\text{ \%}}\text{ = }\frac{142}{58}

Step 8 :

Taking the inverse ( or reciprocal ) of both sides yields:

\frac{x\text{ \%}}{100\text{ \%}}\text{ = }\frac{58}{142}\begin{gathered} x\text{ = }\frac{58\text{ x 100}}{142} \\ \text{x = }\frac{5800}{142} \\ x\text{ = 40.85\%} \end{gathered}

CONCLUSION:

Therefore, 58 is 40.85 % of 142.
