Answer:

I may be wrong here because this is a topic I haven't used in quite a while, but I believe the answer is 1/3.

Step-by-step explanation:

So you take the fractions and line them up next to each other and look for any cancellations. they can only be diagonal so you can only cancel a numerator to a denominator and vice versa. Here you will see that the 8's both line up to be canceled. now you just get rid of them and put 1's. now it will look like this: 1/9 of 3/1. Here's the hardest part. The cancellations are also done for any factors, so 3 and 9 are compatible as well. You divide by the smaller number to get a whole number. If you do not get a whole number, you cannot cancel so you leave it alone. Either way, you divide 3 by 3 and 9 by 3, and now your problem should look like this: 1/3 of 1/1. 1/1 is simply just one so now you are left with a much simpler 1/3 of 1, which is 1/3. Thanks for the question.

Answer:

The interest is $756.

The balance is $2,556.

Step-by-step explanation:

I = Prt

I = $1,800 * 0.07 * 6

I = $756

The interest is $756.

$1800 + $756 = $2,556

The balance is $2,556.

Answer:

X=18.0

Step-by-step explanation:

It says round to the nearest tenth, which is 1 digit after the . Even though 18.02 is correct it wants you to round so X= 18.0

Final answer is X=18.0

The value of x is 18.0 rounded to nearest tenth.

Cosine law is a formula relating the length of the sides of a triangle to the cosine of one angle of the triangle.

u² = s² + t² - 2(s)(t)·cos U

We are Given Triangle with sides, 16, 30, and x, and a measure of an angle corresponding to x = 30°

Required: Value of x to the nearest tenth

Using the Cosine rule:

c² = a² + b² - 2abcos(C)

Let c = x, a = 16, b = 30

C = 30°

Thus,

c² = 16² + 30² - 2 x 16 x 30 x cos 30°

c² = 256 + 900 - 960 x 0.8660

c² = 1,156 - 831.36

c² = 324.64

c = √324.64

c = 18.017769

x ≈ 18.0 (rounded to nearest tenth)

Answer (assuming it can be in slope-intercept form):

[tex]y = -x[/tex]    

Step-by-step explanation:

1) Use the point-slope formula [tex]y-y_1 = m (x-x_1)[/tex] to write the equation of the line in point-slope form. Substitute [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] for real values.

Since the [tex]m[/tex] represents the slope, substitute -1 in its place. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of a point the line intersects, use the x and y values of the point (-5,5) for the formula. Substitute -5 for [tex]x_1[/tex] and 5 for [tex]y_1[/tex].

[tex]y-(5) = -1(x-(-5))\\y-5 = -1(x+5)[/tex]

2) From the above equation, isolate y to place the equation in slope-intercept form and find the final answer:

[tex]y-5=-1(x+5)\\y-5 = -x -5\\y = -x + 0\\y = -x[/tex]

Answer:

f(2+h)=-(h+2/3)^2+1/4

f(x+h)=-(x+h-1/2)^2+1/4

Step-by-step explanation:

1. f(2+h)=(2+h)-(2+h)^2=2+h-4-4h-h^2=-h^2-3h-2=-(h^2+3h+2)

=-(h+2/3)^2+1/4

2. Let (x+h)=a, then rewrite the equation into f(a)=a-a^2.

a-a^2=-(a^2-a)=-[(a-1/2)^2-1/4]=-(a-1/2)^2+1/4.

Insert a=x+h, f(x+h)=-(x+h-1/2)^2+1/4

Answer:

Step-by-step explanation:

Use consistent units. The length of the roller is 2.8 m. The diameter is 168 cm = 1.68 m

Circumference of roller = 1.68π m

Contact area of roller = 1.68π × 2.8 = 4.704π m²

Each rotation levels 4.704π m² of the playground.

Area of playground = 750 rotations × (4.704π m²)/rotation

= 3528π m²

≈ 11,084 m²

Answer:

Step-by-step explanation:

18. x + 25 = 55

     x = 30

19. 2x - 5 = 95

     2x = 100

      x = 50

20. 3x - 22 = 2x + 26

     x - 22 = 26

     x = 48

21. 3x - 18 + 105 = 180

    3x + 87 = 180

    3x = 93

      x = 31

22. 19x + 17x = 180

      36x = 180

       x = 5

   27(5) = 135

23. 5x + 40 + 2x = 180

7x + 40 = 140

7x = 140

x = 20

5(20) = 100

2(20) = 40

5(20) + 40 = 100 + 40 = 140
