#1:

What is Carl’s constant rate of speed (in miles per hour)? 12 mph

How many miles will Carl have traveled after 2 hours? 24 Miles.

What is the slope of this line? -4

What is the value of  y when x = 3? y = 22

What is the rate (in dollars per ticket)? 15/1 | $15 per ticket

How much money will the theater earn if it sells 150 tickets? $2250

What does the point (30, 60) mean? (Hint: What is being graphed on the x-axis? What is being graphed on the y-axis?) (30,60) is equal to x=30 and y=60.

If Karen uses her cell phone for less than 30 hours a month, which company should Karen choose? Why?

I think that Karen should use Company K because if she uses Company J, there would already be an extra fee of $30 from the monthly payment. Instead, Company K doesn’t have the monthly payment plan, but the hourly price is two times pricier but cheaper. To make it simple, let’s say Karen use her phone for about 25 hours for the whole month.

Company J: $30 + $25(1) = $55

Company K: 25(2) = $50

Answer: Choice A) There must be a vertical asymptote at x = c

Explanation:

The first limit $\displaystyle \lim_{x\to c^{-}}h(x) = -\infty$ says that as x approaches c from the left side, the f(x) or y values approach negative infinity. So the graph goes down forever as x approaches this c value from the left side.

The limit $\displaystyle \lim_{x\to c^{+}}h(x) = \infty$ means that as x approaches c from the right side, the y values head off to positive infinity.

Either of these facts are enough to conclude that we have a vertical asymptote at x = c. We can think of it like an electric fence in which we can get closer to, but not actually touch it.

When building a house, the number of days required to build varies inversely with with the number of workers. One house was buil

Helga [31]

Let d represent number of days and n represent number of workers.

We have been given that when building a house, the number of days required to build varies inversely with with the number of workers.

We know that the equation $y=\frac{k}{x}$ represents the relation where y is inversely proportional to x and k is the constant of proportionality.

So our required equation would be $d=\frac{k}{n}$

Upon substituting our given values, we will get:

$19=\frac{k}{35}$

$k=19\cdot 35$

$k=665$

Since constant of proportionality is 665, so our equation would be $d=\frac{665}{n}$ .

To find the number of days it will take to build a similar house with 5 workers, we will substitute $n=5$ in our equation as:

$d=\frac{665}{5}$

$d=133$

Therefore, it will take 133 days for 5 workers to build a similar house.

In ∆abc, m∠cab = 2x and m∠acb = x + 30. if line segment a b is extended through point b to point d, m∠cbd = 5x − 50. what is t

Allisa [31]

The answer is option "3, 40".

m∠cab = 2x
m∠acb = x + 30
m∠cbd = 5x − 50
Now,
m∠cab + m∠acb = m∠cbd
2x+x+30 = 5x-50
2x+x-5x = -50-30
-2x = -80
x = 40

Advocard [28]

Answer:

The answer is "Choice A".

Step-by-step explanation:

Please find the complete question in the attachment file.

Throughout this question by acceptance of its zero hypotheses becomes equal to "the failure to accept the zero hypotheses." Its best answer is to refuse the null hypothesis or conclude how he had no effects on vibrant socks mostly on basis of this study, that's why the above given choice is correct.
