Note that both sides were multiplied by 5.

So that would be "Multiplication Property of Equality."

Basically, this property states that if a=b, then ac = bc.

17. You have $850 to buy new carpet for the game room. The dimensions of the game
gregori [183]

Answer:

Cost of new carpet per square foot should be less than or equal to $3.54.

Step-by-step explanation:

Given:

Money have to buy carpet = \$850

dimension of game room is 20 feet by 12 feet

So we can say length l = 20 feet

and width w = 12 feet

let x be the cost per square foot for new carpet.

Assuming game room to be rectangular in shape we will find the area of it.

Area of room = length \ l \times width \ w = 20 ft\times 12 ft = 240 \ ft^2

Total area \times cost per square feet ≤ Total money we have

Hence,

240 \ ft^2 \times x \leq \$850\\\\x\leq \frac{\$850}{240 \ ft^2}\\\\x\leq \$3.54 \ per \ ft^2

Hence Cost of new carpet per square foot should be less than or equal to $3.54.

Does sine inverse have an exponent? If not, why is there a negative one there? If so, why can't you just divide?
Fofino [41]

Answer:

see below

Step-by-step explanation:

the actual way of writing sin inverse is arcsine, not sin⁻¹

since the output of sin is from -1 to 1, the domain of arsince is from -1 to 1. This is different than 1/sin(x), whose domain is all real numbers. we now write sin⁻¹ to fit it on the tiny buttons on our calculators

What is the value of y in the relative frequency table? Round the answer to the nearest percent.
Ulleksa [173]
Given a relative frequency table is made from data in a frequency table.

Frequency Table
               G                    H              Total
E            12                   11                23

F            14                    8                 22

Total       26                   19                45

Recall that the relative frequency table is obtained from the Frequency table by dividing each entry of the frequency table by the ovarall total of the frequency table.

Thus the relative frequency table of the frequency table above is given by:

Relative Frequency Table
                        G                                       H                                  Total
E         12/45 = 0.27 = 27%          11/45 = 0.24 = 24%       23/45 = 0.51 = 51%

F         14/45 = 0.31 = 31%          8/45 = 0.18 = 18%        22/45 = 0.49 = 49%

Total    26/45 = 0.58 = 58%         19/45 = 0.42 = 42%      45/45 = 1.00 = 100%

For the given relative frequency table with the missing value y being the value of the relative frequency of E and G.

Therefore, the value of y is 27%
