4n = - 6

n = - 6/4

n = - 3/2

And that it

Answer:

n = 1.5

Step-by-step explanation:

So, you left off on where we subtracted 40 from both sides.

34 - 40 = -6

4n = -6

Now, divide both sides by 4 to ultimately isolate the variable:

4n/4 = -6/4

Therefore your answer is -1.5

Step-by-step explanation:

not sure where the click but the angles of 52 degree angle

The measure of the angle x in the given figure is 142°.

When two lines meeting at a point, it will form angle.

We know that, if two lines meeting at a point and forms a straight line then the angle on the either side of the line is 180°.

Here, in the given figure: (x + 38°) = 180°

Therefore the measure of the angle x = (180° - 38°) = 142°.

Answer:

I think its true

Step-by-step explanation:

Answer:

The dimensions are 7.4m by 15.1 m (to the nearest tenth).

Step-by-step explanation:

Area = length * width

If the width = x then the length = 3x - 7 so

Area x(3x - 7) = 111

3x^2 - 7x - 111 = 0

Using the quadratic formula:

x  = [ -(-7) +/- √((-7)^2 - 4*3*-111)] / (2*3)

x =  7.36, -5.03.

The width must be positive s it is 7.36 m.

The length = 3(7.36) - 7

= 15.08 m.

Answer:

Step-by-step explanation: they will form a straight line, passing through the origin.

let the radius of the first one be r

then the first point is (2r, 2πr)

slope of line passing through (0,0) and (2r, 2πr)

= (2πr)/(2r)

= π

The slope of the resulting line is π.

The slope of a line is a number that describes both the direction and the steepness of the line.

Given that, A company logo has 4 concentric circles. you graph the points (diameter, circumference) and connect them with a line.

They will form a straight line, passing through the origin.

Let the radius of the first one be r

Then the first point is (2r, 2πr)

Slope of line passing through (0,0) and (2r, 2πr)

= (2πr)/(2r)

= π

Hence, The slope of the resulting line is π.

Answer:

x = 6

Step-by-step explanation:

Since the triangles are isosceles the two bottom angles are equal. So, 71 + 71 + 2 + 6x would help us find x. Now to solve it.

71 + 71 + 2 + 6x = 180

142 + 2 + 6x = 180

144 + 6x = 180

6x = 180 -144

6x/6 = 36/6

x = 6

40 girls

Step-by-step explanation:

Set up a proportion where x is the number of girls in band class:

[tex]\frac{3}{5}[/tex] = [tex]\frac{24}{x}[/tex]

Cross multiply and solve for x:

3x = 120

x = 40

So, there were 40 girls in band class.

Answer: There are 40 girls in band class.

____________________________________________________________

The ratio for this problem is:

[tex]\frac{3}{5} = \frac{24}{x}[/tex]

To get from 3 to 24, you would multiply by 8. You need to do the same thing to 5 to get x.

5 times 8 equals 40.

There are 40 girls in band class.

Answer:

c. 0.55

Step-by-step explanation:

A chosen acre of land is forested and not forested are complimentary event , so let :

F = Chosen land is forested

F = Chosen land is not forested

....and we know  F+F = S

where S is sample space and we know probability ocer whole sample space is 1 , that is P(S)=1 , and we know F and F are independent so

P(F+F) = P(S)

P(F) + P(F)=1

We have given that probability of forest land in randomly chosen an acre land in Canada have probability 0.45 so P(F)=0.45 so ,

0.45 + P(F) = 1

P(F) = 1 - 0.45

P(F) = 0.55

Hence, the probability that the chosen acre is not forested is 0.55

b. -2,-4,-8,-16,-32 thats the answer i think

The arithmetic sequences are:

B) -2, -4, -8, -16, -32, ...

C) 0, 6, 12, 18, 24, ...

The correct options are B and C.

A series of integers called an arithmetic progression or arithmetic sequence (AP) has a constant difference between the terms.

An arithmetic sequence is a sequence of numbers where each term is obtained by adding a fixed number, called the common difference, to the previous term. We can check which of the given sequences satisfy this definition:

A) 0, 5, 11, 18, 24, ...

The common difference between consecutive terms is not the same: the difference between the first two terms is 5, the difference between the second and third terms is 6, the difference between the third and fourth terms is 7, and so on. Therefore, this sequence is not an arithmetic sequence.

B) -2, -4, -8, -16, -32, ...

The common difference between consecutive terms is multiplied by -2: the difference between the first two terms is -2(-2) = 4, the difference between the second and third terms is -4(-2) = 8, the difference between the third and fourth terms is -8(-2) = 16, and so on. Therefore, this sequence is an arithmetic sequence with a common difference of -2.

C) 0, 6, 12, 18, 24, ...

The common difference between consecutive terms is 6. Therefore, this sequence is an arithmetic sequence with a common difference of 6.

D) 1, -3, 9, -27, 81,...

The common difference between consecutive terms is multiplied by -3: the difference between the first two terms is -3, the difference between the second and third terms is -3(-3) = 9, the difference between the third and fourth terms is -9(-3) = 27, and so on. Therefore, this sequence is not an arithmetic sequence.

Therefore, the arithmetic sequences are options B and C.

Answer:

Step-by-step explanation:

1) The answer is D

g(x) = 2x-8 if we put the corresponding values of x in the table we get the exact same values of y example

[tex]g(x)=2x-8\\g(5)=2(5)-8\\g(5)=2\\g(7)=2(7)=8\\g(7)=6[/tex]

so we can see that our values match with the table's values for part D)

2)The answer is C

Range corresponds to the values of y and here the function in the image shows the maximum value of y is 2 and then it decreases to 1 , 0 , -1 and so on so option C is correct y<2
