!!!!!!!!!PLEASE HELP!!!!!!!!

Answer:

Step-by-step explanation:

In similar triangles corresponding triangles are in same ratio.

[tex]\frac{15}{5}=\frac{12}{y}[/tex]

Cross multiply,

15 * y = 12 * 5

     y = [tex]\frac{12*5}{15}[/tex]

      y = 4

Answer:

The common ratio is 2.

Step-by-step explanation:

3 : 6 : 12

1 : 2 : 4

Answer:

C.  y = -2/3 x + 4

Step-by-step explanation:

y = mx + b

From the graph we see that b = 4, and m = 2/3.

y = -2/3 x + 4

360 meters

Answer:

i hope this helps you

Step-by-step explanation:

answer is c

[tex]2\sqrt{5}\cdot \:4+5\sqrt{2}\cdot \:4[/tex]

[tex]\mathrm{Multiply\:the\:numbers:}\:2\cdot \:4=8[/tex]

[tex]=8\sqrt{5}+5\cdot \:4\sqrt{2}[/tex]

[tex]\mathrm{Multiply\:the\:numbers:}\:5\cdot \:4=20[/tex]

[tex]=8\sqrt{5}+20\sqrt{2}[/tex]

[tex]Answer = =8\sqrt{5}+20\sqrt{2}[/tex]

Answer:

21√6

Step-by-step explanation:

Here we are to combine 2√54 and 5√24, and want to find any factor that these two quantities may have in common.

2√54 can be factored:  2√54 = 2√9√6, or 2[√6√9], or 6√6

Similarly, 5√24 =5√6√9, or 15[√6]

These two results can and should be added together:  7*3√6 = 21√6

Answer:

SAS

Step-by-step explanation:

SAS (Side-Angle-Side) is a proof of congruence for two triangles. Since C stipulates that [tex]\angle ENM=\angle ZNM[/tex], the two triangles would share two sides and the angle between them, thus being congruent from SAS.

Step-by-step explanation:

Answer:

Angle 1 is 105°

Angle 2 is 75°

Step-by-step explanation:

Angle 2 is the same angle as angle 6 which is 75°

Angle 1 can be found by subtracting 75° (angle 2) from 180° which is the angle of a straight line. Which equals 105°.

Hope this helps! :)

Answer:

8. 67 sure 100% so it will be A

9. I am not sure but the answer will be 100 or 120 so it will A or B

Good luck XD

Answer:

Step-by-step explanation:

That appears to be approximately 45 degrees, so to the nearest 10, I would put that at about a 50 degree angle.

Step-by-step explanation:

let the percent of found balloons be x

given,

total number of balloons= 70

number of found balloons= 28

according to the question,

x% of 70= 28

x/100 × 70 = 28

x=40

hence 40% of the balloons were found

Answer:

use substitution

(5 x 7) - (3 x 8) + 11= 35 - 24 + 11= 22

Answer:

22

Step-by-step explanation:

Answer:

The number is -1.

Step-by-step explanation:

Set up an equation:

Variable n = number

8 × n + 4 = -4

Use PEMDAS

8n + 4 = -4

Isolate the variable:

8n = -8

n = -1

Check your work:

8 × -1 + 4 = -4

-8 + 4 = -4

-4 = -4

Correct!

Answer:

-1

Step-by-step explanation:

Write out the equation in numbers.

1. Eight times a number = 8x

2. Added to four = +4

3. Is -4 = =-4

4. Now put it together- 8x + 4 = -4

5. Subtract 4 from each side- 8x = -8

6. Divide both sides by 8- x = -1

Answer:

[tex]b=\frac{1}{6}[/tex]

Step-by-step explanation:

In [tex]f(x)=a\cos(b(x-c))+d[/tex], [tex]b[/tex] represents a constant related to the period of the function. Here's how it's related:

[tex]b=\frac{2\pi}{T}[/tex], where [tex]T[/tex] is the period of the function.

We're given [tex]T=12\pi[/tex], so solving for [tex]b[/tex]:

[tex]b=\frac{2\pi}{12\pi}=\boxed{\frac{1}{6}}[/tex]

Answer:

75

Step-by-step explanation:

f(1) = 7

f(n) = 3f(n-1) + 3

So what you are trying to do here is find the recursive value (that's what it is called) for f(n). Computers love this sort of thing, but we humans have to do it slowly and carefully.

So let's try f(2)

That means that f(2) = 3*f(n-1) + 3

but if f(2) is used it means that you have to know f(2-1) which is just f(1) and we know that.

so f(2) = 3*f(1)+3

f(2) = 3*7 + 3

f(2) = 21 + 3

f(2) = 24

Now do it again. We now know F(2), so we should be able to find f(3)

f(3) = 3*f(3 - 1) + 3  

f(3) = 3*f(2) + 3      We know that f(2) = 24

f(3) = 3* 24 + 3

f(3) = 72 + 3

f(3) = 75

Answer:

{ 11, 19, 27, 35 }

Step-by-step explanation:

To find the range substitute each value of x from the domain into the relation

x = 3 : y → 4(3) - 1 = 12 - 1 = 11

x = 5 : y → 4(5) - 1 = 20 - 1 = 19

x = 7 : y → 4(7) - 1 = 28 - 1 = 27

x = 9 : y → 4(9) - 1 = 36 - 1 = 35

range is { 11, 19, 27, 35 }
