43

Step-by-step explanation:

angle sum property of quadrilateral

87+ 103 + 127+ x = 360

317 + x = 360

x= 360-317

Jace is a songwriter who collects royalties on his songs whenever they are played in a commercial or a movie. Jace will earn $50

riadik2000 [5.3K]

Answer:

The number of commercials is 340 and the number of movies are 334.

Step-by-step explanation:

Let the number of commercials be = C

number of movies be = M

According to given conditions:

C = 6 + M --------- eq1

C + M + 6 = $680 ------ eq2

Putting eq1 in eq2:

6 + M + 6 + M = $680

12 + 2M = $680

Subtracting 12 from both sides:

2M = $680 - 12

2M = 668

Dividing both sides by 2:

M = 668/2

M = 334

For finding number of movies put value of M in eq 1

C = 334 + 6

C = 340

So The number of commercials is 340 and the number of movies are 334.

i hope it will help you!

4x + 3y = 5<br> 2x – y=5<br> Use substitution method

lukranit [14]

Answer: Slope = -2.667/2.000 = -1.333

x-intercept = 5/4 = 1.25000

y-intercept = 5/3 = 1.66667

Step-by-step explanation: Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 1.667 and for x=2.000, the value of y is -1.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -1.000 - 1.667 = -2.667 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

Determine how long it will take an object to rotate through 20.0 revolutions at an angular velocity of 2.8 radians per second. U

Andreyy89

The conversion factor between radians and revolution as measures of angle is 2π rad is equal to 1 revolution. Converting the given angular velocity to rev/s,
(2.8 rad) x (1 rev / 6.28 rad) = 70/157 revolution per second
Dividing the given angle, 20 rev by the velocity,
(20 rev) / (70/157 rev/s) = 44 6/7 s
Thus, the answer is approximately 44.9 seconds.

Hamburger Hut sells regular hamburgers as well as a larger burger. Either type can include cheese, relish, lettuce, tomato, must

Studentka2010 [4]

Answer:

a) 40 different hamburgers can be ordered with exactly three extras

b) 20 different regular hamburgers can be ordered with exactly three extras

c) 7 different regular hamburgers can be ordered with at least five extras

Step-by-step explanation:

The order in which the extras are ordered is not important. So we use the combinations formula to solve this question.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

In this problem:

2 options of hamburger(regular or larger)

6 options of extras(cheese, relish, lettuce, tomato, mustard, or catsup.).

(a) How many different hamburgers can be ordered with exactly three extras?

1 hamburger type, from a set of 2.

3 extras, from a set of 6. So

$C_{2,1}*C_{6,3} = \frac{2!}{1!(2-1)!}*\frac{6!}{3!(6-3)!} = 2*20 = 40$

40 different hamburgers can be ordered with exactly three extras

(b) How many different regular hamburgers can be ordered with exactly three extras?

3 extras, from a set of 6. So

$C_{6,3} = \frac{6!}{3!(6-3)!} = 20$

20 different regular hamburgers can be ordered with exactly three extras

(c) How many different regular hamburgers can be ordered with at least five extras?

Five extras:

5 extras, from a set of 6. So

$C_{6,5} = \frac{6!}{5!(6-5)!} = 6$

Six extras:

6 extras, from a set of 6. So

$C_{6,6} = \frac{6!}{6!(6-6)!} = 1$

6 + 1 = 7

7 different regular hamburgers can be ordered with at least five extras
