What is the percent of 40 of 230

Answer:

Step 1: Simplify both sides of the equation.

−7+3(8n−8)=8(7+3n)

−7+(3)(8n)+(3)(−8)=(8)(7)+(8)(3n)(Distribute)

−7+24n+−24=56+24n

(24n)+(−7+−24)=24n+56(Combine Like Terms)

24n+−31=24n+56

24n−31=24n+56

Step 2: Subtract 24n from both sides.

24n−31−24n=24n+56−24n

−31=56

Step 3: Add 31 to both sides.

−31+31=56+31

0=87

Answer:

x = -7

Step-by-step explanation:

6/x + 8/x + 5 =3

5x + 14 /x =3

Step 1: Multiply both sides by x.

5x+14=3x

5x+14−3x=3x−3x(Subtract 3x from both sides)

2x+14=0

2x+14−14=0−14(Subtract 14 from both sides)

Answer:

1.4x10^-7

Step-by-step explanation:

For Problem 6

First we would divide the first numbers together so 7.84 / 5.6 = 1.4

We then would add the exponenites together so -3+-4=-7

Leading our awnser to be 1.4x10^-7

Step-by-step explanation:

First, put the equation of the line given into slope-intercept form by solving for y. You get y = -2x +5, so the slope is –2. Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is 1/2. Plugging in the point given into the equation y = 1/2x + b and solving for b, we get b = 6. Thus, the equation of the line is y = ½x + 6. Rearranged, it is –x/2 + y = 6.

Answer:

Step-by-step explanation:

81° + a° + 2a° = 180°

81° + 3a = 180°

3a = 180 - 81

3a = 99°

a = 99 ÷ 3

a = 33°

Therefore , a = 33° .

Answer:

B

Step-by-step explanation:

the way i work it out is if you take the product and power it to the third you can easily find out which answer is correct. another way, if you don't have a calculator is to look at the last digit in the number in the square root sign.

For example, 3 square root 64 equals 8. you would look at the 4 and try to find 3 numbers that end in 4 OR is divisible three times by the number. 64 is exactly divisible by 4 only 3 times so you know that it can't be 8.

Answer:

(c+3b)/8 = a

Step-by-step explanation:

c = 8a -3b

Add 3b to each side

c +3b = 8a-3b+3b

c +3b = 8a

Divide each side by 8

(c+3b)/8 = 8a/8

Answer:

The height of the tree is approximately 45.51 ft.

Step-by-step explanation:

The given information are;

The angle of elevation of the top of tree is 36 degrees

The distance backwards Mr. Santos moved = 50 ft.

The new angle of elevation of the top of the tree = 22 degrees

Therefore, we have;

The angle opposite to the 50 ft. side = 180 - (180 - 36) - 22° = 14°

Therefore, we have, by sine rule;

50/(sin(14)) = X/(sin(22))

X = (sin(22)) × 50/(sin(14)) ≈ 77.42 ft.

The height of the tree, T =  X × sin(36°)

T = 77.42 ft. × sin(36°)  ≈ 45.51 ft.

The height of the tree is approximately 45.51 ft

Answer:

I am divisible by 5.

So your ones digit is 0 or 5

I am an even number.

So your ones digit is 0.  We fill that in.

_ _ 0

My tens digit is 1.

So we fill that in.

_ 1 0

My tens digit is greater than my ones digit.

Well, of course 1 is greater than 0. We didn't need to be told that.

I have only one odd digit.

Since the 1 is odd, the hundreds digit is even, 2,4, or 8

I am less than 400.

So your hundreds digit is 2.  Fill that in and we're done.

2 1 0

My hundreds digit is greater than my tens digit.

Of course 2 is greater than 1, we didn't need to be told that.

I am divisible by 3.

Of course 210 is divisible by 3.  We didn't need to be told that.

Answer:

It's not a function

Step-by-step explanation:

Due to the fact that at one x point there are multiple y values so this cannot be a function. The graph also does not pass the vertical line test, therefore it is not a function.

1. The graph is not represent a function.

2. The table shown in figure is represent a function.

What is Function?

A relation between a set of inputs having one output each is called a function.

Given that;

The graph is shown in  shown in figure.

And, In the table;

Value's of x are - 2, 1 , 0 , 2

And values of y are 5, 4 3 , 4

Now,

To check the graph is the function or not, we use vertical line test.

If the vertical line draw parallel to y - axis and it cuts more than one points in the graph, then the graph is not a function.

Here, When we draw a vertical line which is parallel to y - axis then it cuts more than one point, so it is not a function.

Thus, The graph is not represent a function.

2. In the table;

Value's of x (input) are - 2, 1, 0, 2.

And values of y (output) are 5, 4, 3, 4.

Clearly, Every input have exactly one output.

So, By definition of function;

The table shown in figure is represent a function.

Therefore,

1. The graph is not represent a function.

2. The table shown in figure is represent a function.
