Answers

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:

6.519801752°

Step-by-step explanation:

Let θ represent the angle of depression

tanθ=40/350

θ=tan^-1(40/350) *tan^-1 means inverse tan*

θ=6.519801752°

-6 + x = 4x pls help ! ​

Answers

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

So therefore,

Your answer would be x=-2

What is the mode, mean, median for these numbers?
{18,18,63,63,84}

Answers

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.

What are statistics?

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.

The ratio of boys to girls in a class is 5 : 6. If there are 20 boys, how many girls are there?

Answers

Answer:24

Step-by-step explanation:

this symbol (:) is equivalent to a division sign. We can set up an equation; 5/6=20/x. For this specific problem, we can see that you can multiply 4 to reach 20. Then you can multiply 6 also by 4 and get 24. Generally, you should cross multiply. 5x=120; x=24. The final answer is 24 girls.

Solve this system of equations by substitution
x=y+3
x+7=2y

Answers

Answer:

(13, 10 )

Step-by-step explanation:

Given the 2 equations

x = y + 3 → (1)

x + 7 = 2y → (2)

Substitute x = y + 3 into (2)

y + 3 + 7 = 2y

y + 10 = 2y ( subtract y from both sides )

10 = y

Substitute y = 10 into (1) for corresponding value of x

x = 10 + 3 = 13

solution is (13, 10 )

A class of 195 students went on a field trip. They took 19 vehicles, some cars and some buses. If each car
holds 5 students and each bus hold 25 students, how many buses did they take?

Answers

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.

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
