Answer:

a. 250$

b. 200+50x

Step-by-step explanation:

#1 What is the total cost to use the cell phone plan for one month?

GIVEN:

Startup price=$200

Charge per month=50$

SOLVE:

The total cost for one month will be the startup price+ charging price for one month.

200+50=250$

#2 What is the total cost for x months?

The total cost for x months will be the startup price+charging price for x months.

200+50x

Hope this helps!! :)

Yea. The text book is either wrong or it knows something that we don't. Like as to why they would need to have two more feet. You're right though

Two over twenty-two plus six over eleven

kirill [66]

$\frac{2}{22}+\frac{6}{11}$

Simplify $\frac{2}{22}$ to $\frac{1}{11}$

$\frac{1}{11}+\frac{6}{11}$

Both are over 11, so, just sum.

$\frac{1+6}{11}$

$\frac{7}{11}$

Determine if each statement about the relation {(3,7),(5,1),(6,4),(2,5)} is true or false.

s2008m [1.1K]

Answer:

a. true

b. true

c. True

Step-by-step explanation:

a. The domain of a relation includes all possible set of data that are the x-values. Therefore, the domain of the relationship given would be: {2, 3, 5, 6}.

a is True.

b. The range includes all corresponding y-values. Therefore,

Range would be {1 4, 5, 7}

b is Tire.

c. There's 5 on both range and domain.

c is hungry.

A bag contains 7 red marbles, 2 blue marbles and 3 green marbles. If two marbles are drawn out of the bag, what is the exact pro

son4ous [18]

Answer:

Therefore the probability of getting both blue marbles is $\frac{1}{66}$ .

Step-by-step explanation:

Probability : The ratio of favorable outcomes to the total outcomes.

Given that a bag contains 7 marbles which are red in color, 2 marbles which are blue in color and 3 marbles which are green in color.

Total number of marbles = (7+2+3) = 12

The probability of getting a blue on first drawn is

$=\frac{\textrm{No. of blue marbles}}{\textrm{Total number marbles}}$

$=\frac{2}{12}$

$=\frac16$

Now the number of blue marbles = (2-1)= 1 [ since 1 blue marbles is drawn]

Total number of marbles = (12-1) =11

The probability of getting a blue marble on second drawn is

$=\frac{\textrm{No. of blue ball}}{\textrm{Total number ball}}$

$=\frac{1}{11}$

Therefore the probability of getting both blue marbles is

$=(\frac1 6 \times \frac1 {11})$

$=\frac{1}{66}$

The radius of a circle is 4 feet. What is the area of a sector bounded by a 45° arc?

DIA [1.3K]

Answer:

$Area = 6.28\ ft^2$ or $Area = 2 \pi\ ft^2$

Step-by-step explanation:

Given

$Radius, r = 4ft$

$Angle, \theta = 45$

Required

Calculate the area of the sector

When angle is given in degrees, the area of sector is calculated as thus;

$Area = \frac{\theta}{360} * \pi * r^2$

$Substitute\ r = 4\ and\ \theta = 45$

$Area = \frac{\theta}{360} * \pi * r^2$ becomes

$Area = \frac{45}{360} * \pi * 4^2$

$Area = \frac{45}{360} * \pi * 16$

$Area = \frac{45*16}{360} * \pi$

$Area = \frac{720}{360} * \pi$

$Area = 2 * \pi$

$Area = 2 \pi\ ft^2$

The above is the area in terms of π

Solving further.... (Take π as 3.14)

$Area = 2 \pi\ ft^2$ becomes

$Area = 2 * 3.14\ ft^2$

$Area = 6.28\ ft^2$

Hence, the area of the sector is

$Area = 6.28\ ft^2$ or $Area = 2 \pi\ ft^2$
