Answer: 1/4

Step-by-step explanation:

Answer:

1/4 would be your answer.

Step-by-step explanation:

Hope this helps!, and if this Is wrong someone correct me.

Answer:

A is false  (Y is far left of 0, so it is a negative. H is close to 0 so it is positive. Y is farther from zero, so it is bigger. For example, Y could be -7, and H could be 3. The sum of -7 and 3, would be -5.

B is false (E is on the left of 0 so it is negative. Y is on the left of zero so it is also negative. Negative divided by a negative is a positive )

C is false  (H is positive and E is negative. Positive times a negative equals a negative.)

D is true (A is close to zero, so it is a small positive number. H is farther from zero, so it is a larger positive number. For example, A can be 2 and H can be 5. So, 3 - 5 would equal a negative.)

Answer:

C. y = 1/4x -2

Answer:

x = 50

Step-by-step explanation:

101 + (x + 29) = 180

130 + x = 180

x = 180 - 130

x = 50

Answer:

50°

Step-by-step explanation:

in order ro find x you would need to solve for 101° ( x + 29) = 180° if you replace x with 50 then you equation would be true!

Answer:

60 degrees

Step-by-step explanation:

a straight line is 180 degrees

2x= 120 degrees

x=60 degrees

Answer:

The value of x is 60°

Step-by-step explanation:

For a given Straight Line

We know that, The straight angle is an angle equal to 180°

So,

3x = 180

Divide by 3 from both side

3x/3 = 180/3

x = 60°

Thus, The value of x is 60°

Answer:

I think 1/6

Step-by-step explanation:

There are 6 sides on a dice and only one 4. So then you have a 1/6 chance of rolling 4.

Answer:

1/6

Step-by-step explanation:

There are 6 numbers on a die 1,2,3,4,5, and 6. If one number was picked out it would be 1/6

Answer:

Vertex coordinates; (h,k) = (2, -1)

Step-by-step explanation:

Vertex form of a parabola is;

y = a(x - h)² + k

Now, we are given;

x² - 16y - 4x - 12 = 0

Rearranging, we have;

x² - 4x = 16y + 12

Let's complete the square on the left hand side;

First add square of half of the coefficient of x to both sides;

x² - 4x + (-½ × 4)² = 16y + 12 + (-½ × 4)²

x² - 4x + 4 = 16y + 12 + 4

LHS can be expressed as;

(x - 2)² = 16y + 16

16y = (x - 2)² - 16

Divide both sides by 16 to get;

y = (1/16)(x - 2)² - 1

Comparing this with y = a(x - h)² + k, we have;

a = 1/16

h = 2

k = -1

(h,k) = (2, -1)

Answer:

0.9772 or 97.72%

Step-by-step explanation:

P(58<X<78) = normalcdf(58,78,64,3) = 0.9772484056 = 0.9772

The area under the curve would be 0.9772 or 97.72%

Answer:

B. x = 4

Step-by-step explanation:

The two triangles have two congruent sides and a congruent angle. You can say ΔBAC ≅ ΔEDF because of SAS. Corresponding parts of congruent triangles are congruent, so you can say:

BC = EF

And we can substitute their values:

6x - 1 = 23

6x = 24

x = 4

Answer:

x = ±4 (x = 4 and x = -4)

Step-by-step explanation:

4x²-16 = x²+32

3x²-16 = 32

3x² = 48

x² = 16

x = ±4

Therefore, x = 4 and x = -4

Answer:N=11

Step-by-step explanation: 16-5 is 11, and that is equal to N

Answer:

6

Step-by-step explanation:

I am unable to sketch a picture for you but I will do my best to help you understand. We know that our length of the first rectangle is 18 cm and the width is 6 cm. At the moment we don't need 18 so we'll put that to the side for now and focus on the width. We understand that in a second similar rectangle, the width is 2 centimeters. in order to find our scale, we must divide the larger width by the smaller width. This means we will divide 6cm by 2 cm. 6/2=3  This means that we also divide 18 by 3 since the similar rectangle is smaller and we are figuring out the missing side. After dividing 18 by 3 we should get an answer of 6. 18/3=6  Which means that our similar rectangle has a length of 6 cm and a width of 2 cm.

I also want to mention that similar rectangles are not the same rectangle however you can think of them as enlargerd/shrunk versions of the original rectangle. I hope this helps.
