Answer:

175.

Step-by-step explanation:

In this question, translate the words into the symbols. "84" is 84, "%" is 1/100, "what" is x, the unknown, "of" is *, "is" is =, and "175" is 175. Therefore the words can be translated into an equation given below:

84 * x / 100 = 147

84x = 14700

x = 175.

Therefore, 84% of 175 is 147!!!

Answer:

<h2>147 is 84% of 175</h2>

Step-by-step explanation:

\bold{METHOD\ 1:}\\\\p\%=\dfrac{p}{100}\to84\%=\dfrac{84}{100}=0.84\\\\84\%\ \text{of}\ x\ \text{is}\ 147\to0.84x=147\qquad\text{divide both sides by 0.84}\\\\x=175\\\\\bold{METHOD\ 2:}\\\\\begin{array}{ccc}100\%&-&x\\84\%&-&147\end{array}\qquad\text{cross multiply}\\\\84x=(100)(147)\\84x=14700\qquad\text{divide both sides by 84}\\x=175

A car is traveling at a steady speed. It travels 1 3/4 miles in 2 1/3 minutes. How far will it travel in ​? In 1 hour​?
antiseptic1488 [7]

Answer:

45 miles.

Step-by-step explanation:

Ok, so it goes 1.75 (1 3/4) miles in 2 minutes and 20 seconds, or 140 seconds. Divide 1.75 miles by 140 and you get 0.0125 miles per second, or 0.75 (3/4) miles per minute. Multiply 0.75 by 60 minutes and you get 45 miles.

The heights (in cm) and arm spans (in cm) of 31 students were measured. The association between x(height) and y(arm span) is sho
abruzzese [7]

Answer:

27.385 cm longer would we expect Mike's arm span to be than George's.

Step-by-step explanation:

We have to find how many centimeters longer would we expect Mike's arm span to be than George's using the equation:

y= 4.5x + 0.977 x

where y= arm span

and x= height

Given:

Mike's height=x = 175 cm

so Mike's arm span= y= 4.5 x + 0.977 x

                                    = 4.5* (175) + 0.977* (175)

                                    = 787.5 + 170.975

                                    = 958.475 cm

George's height = x = 170 cm

so George's arm span= y= 4.5 x + 0.977 x

                                    = 4.5* (170) + 0.977* (170)

                                    = 765 + 166.09

                                    = 931.09 cm

Mike's arm span longer than George's = Mike's arm span - George's arm span

                                                                 = 958.475 - 931.09

                                                                 = 27.385 cm.
