Answer:

76 units

Step-by-step explanation:

In the given figure, a circle with center Q is inscribed in triangle AHD.

Let the circle with center Q touches the side HD at point N.

So, AT & AM, DM & DN and HT & HN are tangents drawn from external points A, D and H respectively.

Since, measure of tangsnts drawn from external point to a circle are equal.

Therefore,

AM = AT = 18

HN = HT = 8

DM = DN = 12

AH = AT + HT = 18 + 8 = 26

AD = AM + DM = 18 + 12 = 30

HD = DN + HN = 12 + 8 = 20

Perimeter of triangle

= AH + AD + HD

= 26 + 30 + 20

= 76 units

Answer:

Mean= the average of the number set= 18+18+63+63+84=246/5=49.2

Median- the number in the middle of the set= 63

Mode- the number(s) that repeat=1 8, 63

Range- the amount between the highest and lowest numbers= 84-18=66

Step-by-step explanation:

The mode, mean, and median of the data will be 18 or 63, 49.2, and 63, respectively.

Statistics is the study of collection, analysis, interpretation, and presentation of data or discipline to collect and summarise the data.

The data set is given below.

18, 18, 63, 63, 84

The mode of the data is given as,

Mode = Frequency of the repeated number

Mode = 18 and 63

The mean of the data is given as,

Mean = (Sum of observations) / (Number of observations)

Mean = (18 + 18 + 63 + 63 + 84) / 5

Mean = 246 / 5

Mean = 49.2

The median of the data is given as,

Median = (n + 1)th / 2

Median = (5 + 1)th / 2

Median = 6th / 2

Median = 3th

Median = 63

The mode, mean, and median of the data will be 18 or 63, 49.2, and 63, respectively.

Step-by-step explanation:

Used a fancy calculator & just took a test like this

good luck, i hope this helps :)

Answer:

x = 32.8599

Step-by-step explanation:

you have the hypotenuse and the side adjacent to the angle, so you use

Cos(x) = adjacent/hypotenuse

so

Cos(x) = 21/25

x = cos^-1(21/25)

put this in a calculator:

x = 32.8599 (rounded)

Answer:

Number of cars = 14

Number of buses = 5

Step-by-step explanation:

Let

x = number of cars

y = number of buses

x + y = 19 (1)

5x + 25y = 195 (2)

From (1)

x = 19 - y

Substitute x = 19 - y into (2)

5x + 25y = 195

5(19 - y) + 25y = 195

95 - 5y + 25y = 195

- 5y + 25y = 195 - 95

20y = 100

y = 100/20

y = 5

Substitute y = 5 into (1)

x + y = 19

x + 5 = 19

x = 19 - 5

x = 14

Number of cars = 14

Number of buses = 5

Based on the number of vehicles and the number that each vehicle can take, the number of buses required is 4 buses.

There are 19 vehicles which take 5 students each. This means that the number of kids entering buses will be:

= 19 x 5

= 95 students

The students entering buses will be:

= Total number of students - Kids in vehicles

= 195 - 95

= 100 students

If each bus takes 25 students, the number of buses required is:

= 100 students / 25

= 4 buses

In conclusion, 4 buses were taken.

Step-by-step explanation:

A graph shows the lines are not parallel. The lines are perpendicular.

__

j has a slope of -2/3 (down 2 for each 3 to the right)

k has a slope of 3/2 (up 3 for each 2 to the right)

These slope values have a product of 1, typical of perpendicular lines.

Answer:

Step-by-step explanation:

Alright so we are going to be simplifying here

-6 + x = 4x Flip sides

x-6=4x

After that,

x-6=4x  Subtract 4x from both sides

-3x-6=0

Step 3

-3x-6=0  Add 6 to the sides

-3x=6

Step 4

-3x=6  Divide the sides by 3

-2

Answer:

(a) 3:4

(b) 3:4

(c) 9:16

Step-by-step explanation:

(a) The ratio of the sides would be 15:20 but after you simplify them (divide by 5), you'd get 3:4

(b) The ratio of the perimeter would be 60:80 because you're multiplying each side length by 4. When you simplify this again (divide by 20), however, it becomes 3:4 again

(c) To find the area, you would multiply the width times height, the ratio would be 225:400. You would get the greatest common factor which is 25 and divide it on both sides to get 9:16
