Answer:

m∠7 = 140º

Step-by-step explanation:

m∠4 = m∠2 + m∠3

120 = 80 + m∠3

m∠3 = 40

m∠3 + m∠7 = 180

40 + m∠7 = 180

m∠7 = 140º

Arthur is treating his friends to a meal at Chez rich. The meals add up to $136.45. If he tips the waiter 15% what is the amount
Ulleksa [173]
Basically you need to find what 15% of 136.45 is. You do this by changing the percent to a decimal, so 15% would be .15. Following this, you would multiply 136.45*.15. This will give your answer.

45ft squared would be the answer i think because the carpet could be smaller or bigger than the area of the room or it wouldn't fit.

An air freshener starts with 33 grams and evaporates. In each of the following situations define a function that gives the remai
grin007 [14]
Hello!

A) 
<span>The mass of the air freshener A decreases by 3.2 grams each day. Define a function, f, to represent this situation.

In this function, the mass of the air freshener A (m) is the dependent variable and the days (t) and the initial amount of the air freshener A (mi) are the independent variables. If the mass decreases by a fixed amount each day, you only have to multiply this amount by the number of days:

</span>m=mi-(3,2*t)

<span>B) The mass of the air freshener B decreases by 3.2% each day. Define a function, g, to represent this situation.
</span>
This function is trickier since there isn't a fixed amount of decreasing. Instead, the rate of decreasing depends on the initial amount of the freshener (mi). You have to include this initial amount in the equation to correctly model it. This is how you do it:

m=mi-(mi* \frac{3,2}{100}*t)

Have a nice day!
