Answer:

32.9

Step-by-step explanation:

70 ------ 100%

x ------- 47%

$47*70=x*100\\\\\frac{47*70}{100} =x\\\\\frac{47*7}{10} =x\\\\\frac{329}{10} =x\\\\x=32.9$

so the 47% of 70 is 32.9 almost 33

How many orders of magnitude bigger is 23,000 than 56?

Daniel [21]

Orders of Magnitude are in terms of scientific notation.

23,000 written in scientific notation is 2.3 x 10^4, it's magnitude is 4 ( the number 10 is raised to)

56 in scientific notation would be 5.6 x 10^1, its magnitude is 1.

4 - 1 = 3

2300 is 3 order of magnitudes larger.

The answer is 3.

Oscar played games vs number of points he scored is, C) positive, linear association.

Step-by-step explanation:

no association is when points Oscar graph will remain between 8to10.
number of games he scored his points remain the same which is mean.
non linear is only when there is no straight line passing.
Linear is either exponential or polynomial.
Positive as the game increase he scoring abilities increases.
Negative as the game increases his scoring decreases.
Negative x axis will have more number of points.
Negative y axis will high to low of the graph.
Linear lines are best way to predict a data doesn't work will all data.

Cole wants to buy carpet to cover his whole living room, except for the tiled floor. The tiled floor is 4 5 6 ft by 2 1 3 ft. Fi

Shtirlitz [24]

Answer:

$Area = 49\frac{25}{36}$

Step-by-step explanation:

Given

Tile

$Length = 4\frac{5}{6}$

$Width = 2\frac{1}{3}$

See attachment for dimension of the floor

Required

Determine the area covered by the carpet

From the attachment, the dimension of the floor is:

$Length = 12\frac{1}{4}$

$Width = 5$

Calculate Area

$Area = Length * Width$

$Area = 12\frac{1}{4} * 5$

$Area = 61\frac{1}{4}$

The area of the tiles is:

$Area = 4\frac{5}{6} * 2\frac{1}{3}$

$Area = \frac{29}{6} * \frac{7}{3}$

$Area = \frac{203}{18}$

$Area = 11\frac{5}{18}$

So, the carpet area is:

$Area = Floor\ Area - Tile\ Area$

$Area = 61\frac{1}{4} - 11\frac{5}{18}$

To improper number

$Area = \frac{245}{4} - \frac{208}{18}$

Take LCM

$Area = \frac{2205 - 416}{36}$

$Area = \frac{1789}{36}$

$Area = 49\frac{25}{36}$

A store manager is marking down chess boards from $25 to $14. What percentage is the discount?

Alborosie

Remember: when calculating percent it will always be over 100. With the given numbers 14 is your part out of the total (25). It should be written as part/whole.

As previously said, the percent is always over 100. (x/100)

In this problem you are given the part (14) and the whole (25). So it would be 14/25. The percent in this problem would be x/100. Now to find percent with the given part/whole, you would multiply 14 with 100. Then simply divide by 25.
