HELP A triangle and its angle measures are shown in the diagram. What is the value of x?

Stolb23 [73]

Answer:

a. 16

Step-by-step explanation:

Triangles = 180 degrees

180 - 80 = 100

100 = (4x - 4) + (0.5x + 32)

4x - 4 + 0.5x + 32 =100

(4x + 0.5x) +(-4 + 32) = 100

4.5x + 28 = 100

4.5x + 28 -28 = 100 - 28

4.5x = 72

4.5x/4.5 = 72/4.5

x = 16

Answer:

13 and 27

Step-by-step explanation:

y= x+14

x+y=40

x+ x+14=40

2x+14=40

40-14=26

so, 2x=26

26/2

=13

so, x=13 and

and y equal 40-13

A 180-watt iHome® is used on an average of three hours a day. Find the cost of listening to the iHome for one week at a cost of

IgorLugansk [536]

<h2>Hello!</h2>

The answer is:

The correct option is:

A. $0.49

<h2>Why?</h2>

From the statement, we know that the iHome is used on average three hours a day, and we are asked to find the cost for a week, so first, we need to calculate the total hours that the iHome is used for, and then, calculate the kilowatt-hour consumption rate.

$TotalTime_{week}=3\frac{hours}{day} *7days=21hours$

$TotalEnergyConsumption_{week}=180watt*21hours=3780watt.hour$

Now, we must remember that:

$1Kilowatt=1000watts$

So,

$3780watts=3780watts.hour*\frac{1KiloWatt}{1000watts}=3.78KiloWatt.hour$

Then, calculating the cost, we have:

$TotalCost_{week}=0.13\frac{dollar}{killowat.hour}*3.78killowat.hour=0.49(dollar)$

Hence, we have that the correct option is:

A. $0.49

Have a nice day!
