Find the value of x

Mathematics
1 answer:
Mumz [18]3 years ago
5 0

Answer:

See Explanation

Step-by-step explanation:

The measure of angle X would be 50 degrees because 65 degrees is already labeled and B would also be 65 degrees so 65 + 65 = 130, and finally subtract 180 - 130 to get the final measure of angle X: 50 degrees

10. Kim gets $7 per hour and gets charged $1 for gloves

Use y to represent her pay and x to represent hours worked.

The equation is y = 7x - 1 because she gets 7 times x hours and there is a minus 1 because of the charge of gloves.

11. The table shows that each increasing hour, 8$ is added. Therefore we need to find the bonus that Kit receives just for showing up. This is when hours equals 0. If 3 hours is 27$ pay, then 2 hours is 19$ pay, 1 hour is 11$ pay and 0 hours is 3$ pay. We find that there is a 3$ bonus just for showing up.

Therefore the equation is y = 8x + 3

12. At x = 0, y = 2 so the y-intercept is 2. The slope is going down 4 and right one which means the slope is -4. The y-intercept is b and the slope is m. If we plug these values into the equation y = mx + b we get:

y = -4x + 2

13. At x = 0, y = -3 so the y-intercept is -3. The slope is going up 1 and right 4 which means the slope is 1/4. The y-intercept is b and the slope is m. If we plug these values into the equation y = mx + b we get:

y = 1/4 x - 3

It is an unfair coin with unknown probability of head and tail. Can you generate even odds using this coin?
Vladimir79 [104]

Answer:

Yes, it can be generated if p = \frac{n}{n+1}, where n is a positive even integer.

Step-by-step explanation:

An odds for an event, is the probability or chance that this event will occur, divided by the probability that it will not occur.

Assume that the probability of getting tail when throwing the coin is p, therefore, the probability of getting a head is (1-p) and the odds for the event of getting tail is \frac{p}{1-p}.

If k is a positive integer, and we assume that the odds of getting a tail are even, then:

\frac{p}{1-p} = 2k

p = 2k - 2kp

p = \frac{2k}{2k+1}

Conclusion: if p = \frac{2k}{2k+1}, for some positive integer k, even odds are generated. For example: p = 2/3, 4/5, 6/7, ...

Suppose Rick has 40 ft of fencing with which he can build a rectangular garden.Letxrepresent the length of the garden and letyre
Lubov Fominskaja [6]

Answer:

20 >= x + y

Step-by-step explanation:

Given:

- The length of garden = x

- The width of the garden = y

- Total fence available = 40 ft

- Rectangular garden

Find:

(a) Write and inequality representing the fact that the total perimeter of thegarden is at most 40 ft.

(b) Sketch part of the solution set for this inequality that represents all possiblevalues for the length and with of the garden.

Solution:

- The perimeter of the rectangular garden is P at most 40 ft:

                              P >= 2*x + 2*y

                              40 >= 2*x + 2*y

                              20 >= x + y

- The sketch of the graph will be all points in the shaded region denoted by the inequality as follows:

                               y =< 20 - x

- See the triangular shaded region.

(TRIANGLE THEOREM) please help!!
alexdok [17]
A^2 + b^2 = c^2
where a and b are the sides, and C is the hypotenuse (longest side)

basically
a + 13^2 = 16^2
so
a + 169 = 256

to find what A is, 256 - 169 = a = 87
but, because a is squared, you need the square root of 87 if it is a whole number, but it isn't-

Answer = \sqrt{87}
