Answer:

The length of  [tex]\overline{AD}[/tex] is 20 inches

Step-by-step explanation:

The given parameters are;

Triangle ABC is similar to triangle DEC, therefore, we can write, ΔABC~ΔDEC

[tex]\overline{AC}[/tex] = 30 inches

[tex]\overline{BA}[/tex] = 18 inches

[tex]\overline{ED}[/tex] = 6 inches

By similar triangles formula, we have;

[tex]\overline{BA}[/tex]/[tex]\overline{ED}[/tex] = [tex]\overline{AC}[/tex]/[tex]\overline{DC}[/tex]

Substituting the known values gives;

18/6 = 30/[tex]\overline{DC}[/tex]

Therefore, [tex]\overline{DC}[/tex] = 30/(18/6) = 30/18 × 6 = 10

[tex]\overline{DC}[/tex] = 10

[tex]\overline{AD}[/tex] = [tex]\overline{AC}[/tex] - [tex]\overline{DC}[/tex] = 30 - 10 = 20

[tex]\overline{AD}[/tex] = 20 inches.

Answer:Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are. The analysis of events governed by probability is called statistics.

Answer:

y = - 3x + 4

Step-by-step explanation:

Line is passing through the points (1, 1) & (0, 4)

Slope of line = (4-1)/(0-1) = 3/(-1) = - 3

Equation of line

y = mx + b

Here m = - 3, b = 4

y = - 3x + 4

Using point (1, 1)

y - 1= - 3(x - 1)

y = - 3x +3 +1

y = - 3x + 4

Answer:

x=5

Step-by-step explanation:

Ok so put them equal to each other

2x+12=3x+7

subtract 12 from both sides

2x=3x-5

subtract 3x from both sides

-x=-5

divide both sides by -1

x=5

Answer:

Tobias repayed a total of $7,200.

Step-by-step explanation:

If Tobias borrowed $20,000, and the annual interest rate is 9% of this per year, then we need to find 9% of 20,000.

20,000 x 0.09 = 1,800

Therefore, the yearly interest rate is $1,800. Now, we need to multiply this by 4.

1,800 x 4 = 7,200

Therefore, Tobias repayed a total of $7,200.

Hope this helps! :D

Answer:

1 solution

Step-by-step explanation:

There is exactly one solution because when both lines are graphed, they intersect at only one point, (1.5,-1).

Answer:

Either no solutions or infinite..

Step-by-step explanation:

I am not exactly sure, but I am taking a guess. IF this equation requires a definite answer, then no solutions. Otherwise, if x or y can equal to any number, then, infinite numbers. I would recommend to look at what other people say before reading this and taking a guess.

Answer:

35 girls

Step-by-step explanation:

First add the ratios together ( 3+5) this will give you 8. Then divide the total number of students by 8, this will get you 7. Now multiply 7 to 3 and multiply 7 to 5. As the ratio of boy to girl is 3 to 5, to find how many girls are in the school play we multiply 7 to 5. This makes 35 girls.

If you want to check, 7 x 3 =21 boys and 7 x 5=35 girls. 35 +21= 56 (the total number of students).

Answer:

500 ft

Step-by-step explanation:

use this formula

The actual distance between first and second ride is 500 ft.

The distance between two point P(a, b) and Q(c, d).

so, the distance PQ = √(c-a)² + (d- b)²

Given:

Starting point = (0,0)

First ride = (0,4)

Second ride = (3,0)

In map, each unit = 100 ft

Using the distance formula

d =  √( 3-0)² + (0-4)²

d = √9+ 16

d= √25

d = 5 units

So, the distance between first ride and second ride in the map is 5 units.

and,1 units  = 100 ft

5 units = 500 ft

Hence, the actual distance between first and second ride is 500 ft.

Answer:

a = 151 degrees

Step-by-step explanation:

180 - 29 = 151

Answer:

151

Step-by-step explanation:

180 -29 = 151

Answer:

a) -9, -10, -11

b)24, 36, 54

c)-10, 20, -40

Step-by-step explanation:

-8 - 1 = -9

-9 - 1 = -10

-10 - 1 = -11

a2 = 16 * 3/2 = 24

a3 = 24 * 3/2 = 36

a4 = 36 * 3/2 = 54

f(2) = 5 * -2 = -10

f(3) = -10 * -2 = 20

f(4) = 20 * -2 = -40

The next three terms of each geometric sequence  are;

a) -9, -10, -11

b)24, 36, 54

c)-10, 20, -40

There are three parameters which differentiate between which geometric sequence we're talking about.

The first parameter is the initial value of the sequence.

The second parameter is the quantity by which we multiply previous term to get the next term.

a) The common difference is;

-8 - 1 = -9

b) The common difference is;

-9 - 1 = -10

c) The common difference is;

-10 - 1 = -11

a2 = 16 * 3/2 = 24

a3 = 24 * 3/2 = 36

a4 = 36 * 3/2 = 54

Therefore, the next terms are;

f(2) = 5 * -2 = -10

f(3) = -10 * -2 = 20

f(4) = 20 * -2 = -40

Answer:

Average rate of change = 3

Step-by-step explanation:

here   a = -3 and b = 4

⇒ Average rate of change = f(b) - f(a)  / b - a

                                            = (27 - 6) / (4 - (-3))

                                            = 21 / 7

                                            = 3

Therefore, Average rate of change = 3

Answer:

(1, 6)

Step-by-step explanation:

Answer:

AC = 23

BD = 23

Step-by-step explanation:

ABCD is a rectangle,

AC and BD are its diagonals.

Diagonals of a rectangle are congruent.

Therefore,

AC = BD

7x - 40 = 2x + 5

7x - 2x = 5 + 40

5x = 45

x = 45/5

x = 9

BD = 2x + 5 = 2*9 + 5 = 18 + 5 = 23

AC = 7x - 40 = 7*9 - 40 = 63 - 40 = 23
