find the unknown angle​

Answer:

C

Step-by-step explanation:

Divide the Y values by the X values to check your answer

Answer:

C

Step-by-step explanation:

The question asks for a 0.3 constant of proportionality between 'x' and 'y'.

So, if you multiplied 0.3 to the number in 'x', you would get the number in 'y'.

By process of elimination, we can find that in A, 0.3 * 6 is not 2 and it's the same for all the other numbers in the table.

For B, 3*0.3 is not 1.8 and 0.3 multiplied by the other numbers in B do not match the number in y.

The only answer that matches is C, 4*0.3 is 1.2, 8*0.3 is 2.4, and 13*0.3 is 3.9.

So, the answer is C.

Answer:

3 ≤ x ≤ 4

Step-by-step explanation:

Step 1: Add 10 to all parts/sections.

Step 2: Divide all parts/sections by 3.

Therefore, the answer is 3 ≤ x ≤ 4.

Answer:

3≤ x≤ 4    

Step-by-step explanation:

-1≤ 3x-10≤ 2

Add 10 to each side

-1+10≤ 3x-10+10≤ 2+10

9≤ 3x≤ 12  

Divide each side by 3

9/3≤ 3x/3≤ 12/3

3≤ x≤ 4    

Answer:

60

Step-by-step explanation:

To find the mean, add all numbers together and divide by the amount of numbers.

Total of number = 660

Number of numbers = 11

660/11 = 60

Answer:

The median is 70.

Step-by-step explanation:

I believe you may have mixed up median with mode.

Here are the definitions of both:

Mode - The value that appears the most in a data set

Median - The middle number in a list of numbers ordered from least to greatest

To find the median of this data set, we must arrange the numbers from least to greatest!

20, 20, 30, 50, 60, 70, 70, 80, 80, 90, 90

Now we just have to figure out the middle number...which is 70!

20, 20, 30, 50, 60, 70, 70, 80, 80, 90, 90

Answer:

y = (1/2)x + 7/2

Step-by-step explanation:

y = ax + b (general form of a linear function)

a = 1/2 (slope)

y = (1/2)x + b

(-3, 2) is on the line, 2 = (1/2)*(-3) + b

2 = -3/2 + b

b = 2 + 3/2

b = 7/2

equation: y = (1/2)x + 7/2

Answer:

425ft.

Step-by-step explanation:

Just add 395 and 30 together.

Hope this helps. Pls give brainliest!

Answer:

425 ft

Step-by-step explanation:

So the snorkeling was 30 ft BELOW sea level while the hike was 395 ft ABOVE sea level.

Below is negative so 30 ft below is -30

Above is positive so 395 ft above is 395

the difference between 395 and -30 looks like this:

395- (-30)

So you can simplify to get this equation:

395+30

which is 425

So the difference between the snorkel and hike is 425 ft

Hope this helps!

Answer:

5. [tex]f(x) = 10,000 (1.5)^x[/tex]

Step-by-step explanation:

==>>We would have to multiply the original amount by 1.50^x because the initial amount would be 1, and 50% increase would be .5 so 1.5 and you raise it to the number of years to show the total increase.

Initial: 10,000

After 1 year

10,000 + (.5*10000)

10,000 + 5000 = 15,000

--

After 2 years

15,000 + (.5*15000)

15,000 + 7500 = 22,500

--

Let's try our equation.

[tex]f(x) = 10,000 (1.5)^x[/tex]

[tex]x=2[/tex]

[tex]10,000(1.5)^2[/tex]

[tex]10,000(2.25) = 22,500[/tex]

Answer:

-22

Step-by-step explanation:

Answer:

4x - 5 = 2(2x + 1)

Step-by-step explanation:

4x - 5 = 2(2x + 1)

4x - 5 = 4x + 2

Then you would subtract the 4x on each side leaving you with:

-5 = 2

And obviously the value of -5 does not equal the value of 2 so therefore this equation has no solution

Hope that was what you were looking for.

Answer:

[tex]\frac{2}{3}[/tex]

Step-by-step explanation:

let the number be n , then

4 - 4n = 2n ( add 4n to both sides )

4 = 6n ( divide both sides by 6 )

[tex]\frac{4}{6}[/tex] = n

The number is [tex]\frac{2}{3}[/tex]

Answer:

Let the number = x

4 - 4x= 2x

4 = 2x+4x

4 = 6x

x = 4/6

x = 2/3

Answer:

The number is -100, Jill can think of something else, now.

Step-by-step explanation:

x = the number

x/4 - 20 = -45 {twenty less than one-fourth of the number is -45}

x/4 = -25 {added 20 to each side}

x = -100 {multiplied each side by 4}

Answer:

-31.25

Step-by-step explanation:

Jill's number=[1/4×(-45)]-20

=-11.25-20

=-31.25

Answer:

1) A number that divides another number evenly is called a factor of that number. For example, 16 can be divided evenly by 1, 2, 4, 8, and 16. So the numbers 1, 2, 4, 8, and 16 are called factors of 16.

2) A number that divides a given set of numbers is called a common factor of the numbers.

Step-by-step explanation:

i hope its right

Answer: 2

Step-by-step explanation:

We can list out their factors

10:1,2,5,10

6:1,2,3,6

Both have the same factors of 2.

Answer: 2

Step-by-step explanation:

since the factors or 10 are 5 and 2

and the factors of 6 are 3 and 2

then 2 must also be a common factor of the other numbers
