given: EC=3AE, DB=3AD
prove: ABC- ADE

Answer:

Let S = starting point

Let ST = length of tunnel

SR = 1414 m

RT = 2236 m

Set up:

ST^2 + SR^2 = RT^2

ST^2 + (1414)^2 = (2236)

Solve for RT to find your answer.

Step-by-step explanation:

Answer:

i feel like its b but im so sorry if im wrong

Step-by-step explanation:

Answer:

b = 15.59

Step-by-step explanation:

a^2 + b^2 = c^2

9^2 + b^2 = 18^2

81 + b^2 = 324

-81             -81  

b^2 = 243

b = 15.59

Pythagorean Theorem -

[tex]a^{2} + b^{2} = c^{2} [/tex]

1 - Input the values!

[tex] 9^{2} + x^{2} = 18^{2} [/tex]

2. Find the exponents!

[tex]81 + x^{2} = 324[/tex]

3. Multi step Equations!

[tex]81 - 81 = 0 \\ 324 - 81 = 243[/tex]

4. Use square roots to find x!

[tex]x = \sqrt{243}[/tex]

Answer: X=The Square Root Of 243

Answer:

-0.25

Simply change the sign and you will get the result.

Answer:

-28/45

Step-by-step explanation:

Here, we want to find the result of a division

What we have to do here is to flip the fraction on the right hand side , then change the sign from division to multiplication

We have this as;

4/9 * -7/5

= -28/45

Answer:

12

Factors : 1,2,3,4,6,12

Answer:

the number can be 12.

1 x 12 = 12

2 x 6 = 12

3 x 4 = 12

Answer:

Surface area of the cube = 294 m²

Step-by-step explanation:

Sidewall of a cube measures in length = 7 m

Formula for the surface area of a cube = Sum of the areas of all six sides of the cube

= 6 × (Side)²

= 6 × (7)²

= 6 × 49

= 294 m²

Therefore, surface area of the cube is 294 m².

Answer:

x = 18

Step-by-step explanation:

Total interior angle of pentagon: 540 degrees

(3x + 23) + (9x - 6) + 95 + 90 + (7x - 4) = 540

19x + 23 - 6 + 95 + 90 - 4 = 540

19x + 17 + 95 + 90 - 4 = 540

19x + 13 + 185 = 540

19x + 198 = 540

19x = 342

x = 18

Answer:

its 18

Answer:

1. 252N = ( x  x )N

2. Factor =

Step-by-step explanation:

Let the starting population size for organisms A and B be represented by N.

For organism A;

Day 0: N

Day 1: 2N

Day 2: N

Day 3: N

Day 4: N

Day 5: N

Day 6: N

Day 7: N

Day 8: N

For organism B;

Day 0: N

Day 1: 2N

Day 2: N

Day 3: N

Day 4: N

Day 5: N

Day 6: N

Day 7: N

Day 8: N

1. After the eight days, organism B's population is larger than organism A's population by;

N - N = 256N - 4N

              = 252N

              = ( x  x )N

2. Organism A's population grows by .

Answer:

a = 45 degrees

Step-by-step explanation:

Since both angles are a, they are equal to each other

Also, we know that the right angle means it measures 90 degrees

So, (180-90)/2 = a

a = 45 degrees

Step-by-step explanation:

Answer:

Geometric Progression is the explicit rule for the given sequence: 11, 22, 44, 88...

First term (a) = 11

Common ratio (r) = 22/11 = 44/22 = 88/44 = 2

Formula used in Geometric Progression is :---

[tex]\boxed{a_n = a {r}^{(n - 1)}}✓\\ [/tex]

where, 'n' is the required term

Answer:

So they just want you to solve the equation if x= -4

d(-4) = -(-4) + -4

y = 4 - 4

The solution would be 0.

Answer:

144 feet to nearest foot.

Step-by-step explanation:

Let the distance between Albert and the point on the ground that the balloon is directly above be x feet Then for Isaac the distance is 400 - x feet

So we have 2 right angled triangles and:

tan 62 = h/x

tan 48 = h / (400- x)         where h is the height of the balloon.

From the first equation x = h / tan 62 so plugging this into the second one:

tan 48 =  h /  ( 400 - h/tan 62)

h = 400 tan 48 - h tan 48 tan 62

h + h tan 48 tan 62 = 400 tan 48

h ( 1 + tan48 tan62) = 400 tan48

h = 400 tan 48 / (1 +  tan 48 tan 62)

= 143.8 feet.

Answer:

Step-by-step explanation:

Hey There!

So when finding probabilities we want to find how many even numbers there are and divide that by the amount of numbers

we see that there are 3 even number ( 2, 16 and 8) and there are 8 numbers in total

So in one spin the probability of it landing on an even number is 3/8

Now to find the probability it will land on an even number in 120 spin we multiply 3/8 and 120

[tex]\frac{3}{8} x 120=45[/tex]

So the reasonable prediction of it landing on an even number out of 120 spins is 45

Step-by-step explanation:

the number of students who plays sport are 1/7 of 35 that means that there  are 35/7 students play sport so there is only 5 of 35 students play sport

so number of students thatn dont play sport are 35 - 5 = 30
