Answer:

12

Step-by-step explanation:

the angles of a triangle all add up to 180

thus, we can combine every term given and set them equal to 180 and solve for x

9x + 72 = 180 \\ 180 - 72 = 108 \\ 108 \div 9 = 12

What is the area of the shaded region in the figure above?
Dafna1 [17]

Answer:

51 m^2

Step-by-step explanation:

Draw a vertical line through the roof peak.  There is a trapezoid on either side.  The average height of the trapezoid is (16 m + 10 m)/2 = 13 m.  The width of one trapezoid is 2.5 m.  Thus, the area of one trapezoid is

(13 m)(2.5 m) = 32.5 m^2.

There are two such trapezoids, so the combined area is 2(32.5 m^2), or 65 m^2.

Now find the area of the open door:  It is (7 m)(2 m) = 14 m^2.

Subtracting this door area from the overall area:  

65 m^2 - 14 m^2 = 51 m^2

Identify Q¹,Q²,Q³ and the IQR of the data: 50,65,70,120,130,145,70,55,45
satela [25.4K]
Q₁=Middle of the median and the first number in an ordered set from least to greatest.

Q₂=Median

Q₃=Middle of the median and the last number in an ordered set from least to greatest.

Order numbers from least to greatest:

45, 50, 55, 65, 70, 70, 120, 130, 145

Now, find the middle of the data set, which is the first 70 in the data set.

Now, from there, find the middle of the first half of the set.

First half: 45, 50, 55, 65

Q₁=52.5 because it is half of 50 and 55.

Second half: 70, 120, 130, 145

Q₃=125 because it is half of 120 and 130.

So your answer is:
 
Q₁=52.5

Q₂=70

Q₃=125

~Hope I helped!~

A class of 25 students had a vote. 24% voted on selection 'a'. 1/5 of the class voted on selection 'b'. And 0.56 voted on select
sattari [20]

<span>To find this out, change all of them into decimals. To change a percent into a decimal, divide the percent by 100. To change a fraction into a decimal, divide the numerator by the denominator. 24% as a decimal is 0.24. 1/5 as a decimal is 0.20. </span>

<span>Multiply each of the decimals by the number of students.</span>

<span>So, </span>

<span>0.24*25= 6</span>

<span>0.20*25= 5</span>

<span>0.56*25= 14</span>

<span><em><u>6 people voted on section A</u></em></span>

<span><em><u>5 people voted on section B</u></em></span>

<span><em><u>14 people voted on section C</u></em></span>

<span>Hope it helps :)</span>
