Acell phone company charges $3.00 to make a phone call plus $0.15 for
each minute for each minute you talk. Which equation would you use to
determine the total cost, c, of a phone call that is m number of minutes
long?
C=0,15 - 300m c-3.00 -0.15m
3.00 = € + 0,19
C = 3,00 + 0.15m
Answer:
Hi there!
Your answer is:
3+.15m =c
I cannot read your answer choices, but that is your answer. I believe your answer choice that matches is the lowest one; C= 3,00 +.15m
Hope this Helps
What is the length of the hypotenuse of the triangle?
Answer:
In geometry, a hypotenuse is the longest side of a right-angled triangle, the side opposite the right angle. The length of the hypotenuse of a right triangle can be found using the Pythagorean theorem, which states that the square of the length of the hypotenuse equals the sum of the squares of the lengths of the other two sides. For example, if one of the other sides has a length of 3 (when squared, 9) and the other has a length of 4 (when squared, 16), then their squares add up to 25. The length of the hypotenuse is the square root of 25, that is, 5.

write the given equation of a line that passes through two given points (0,1) and (2,2)
Answer:
m=slope y = intercept
m= y2-y1 / x2-x1
2-1 / 2-0 = 1 /2
now pick one of the points and put in for y and x
use (2,2) 2= 1/2(2) +b
2=1 + b
2-1 =1-1 +b subtract 1 from each side
1 = b This is your y intercept
Step-by-step explanation:
The equation of the line passing through points (0,1) and (2,2) will be y = ( 1 / 2) x + 1
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Slope= 2-1 / 2-0 = 1 /2
Now pick one of the points and put in for y and x use (2,2).
2= 1/2(2) +b
2=1 + b
2-1 =1-1 +b subtract 1 from each side
1 = b This is your y-intercept
The equation will be written as:-
y = ( 1 / 2) x + 1
Therefore, the equation of the line passing through points (0,1) and (2,2) will be y = ( 1 / 2) x + 1.

A selective college would like to have an entering class of 1200. Because not all students who are offered admission accept, the college admits more than 1200 students. Past experience shows that about 70% of the students will accept. The college decides to admit 1500 students. Assuming that students make their decision independently, the number who accept, X, has the Bin(1500, 0.70) distribution. If this number is lower than 1200, the college will admit students from its waiting list.What is the mean of the distribution of X - that is, the expected number of students who will accept admission
Answer:
The value is [tex]\mu = 1050 [/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 1500
The probability of a student accepting the admission is p = 0.70
Generally the mean off the distribution of X is mathematically represented as
[tex]\mu = np[/tex]
=> [tex]\mu = 1500 * 0.70 [/tex]
=> [tex]\mu = 1050 [/tex]

See below
Step-by-step explanation:
It does not exist because the

doesn't tend to some value it just loop around
[tex]-1, 1[/tex]
for ever
it exist when we have
[tex]\lim_{x\rightarrow \infty}[(\frac{1}{x})][/tex]
there when the value of x increasing the fractions tends to 0
so we can say that when x approaches infinity the value is 0.

6 eggs weigh 3/4 of a pound. How much does each egg weigh?
9514 1404 393
Answer:
1/8 lb or 2 oz
Step-by-step explanation:
You find the weight per egg by dividing the weight by the number of eggs:
(3/4 lb)/(6 eggs) = 3/24 lb/egg = 1/8 lb/egg
A pound is 16 ounces, so 1/8 lb is 2 oz.
Each egg weighs 1/8 lb or 2 oz.

Hello your question has some missing part below is the missing part
The Zagat Restaurant Survey provides food, decor, and service ratings for some of the top restaurants across the United States. For 15 restaurants located in Boston, the average price of a dinner, including one drink and tip, was $48.60. You are leaving for a business trip to Boston and will eat dinner at three of these restaurants. Your company will reimburse you for a maximum of $50 per dinner. Business associates familiar with these restaurants have told you that the meal cost at one-third of these restaurants will exceed $50. Suppose that you randomly select three of these restaurants for dinner.
Answer : 0.2637
Step-by-step explanation:
Average price of dinner including one drink and a tip in Boston = $48.60
Number of restaurants = 15
number of restaurants whose meal cost more than $50 = 1/3 * 15 = 5
Probability that None of the meals will exceed the cost covered by your company
ATTACHED BELOW is the solution
P( none ) = 0.2637
which property of equality is 4x-3=x+9
Answer:
Two equations that have the same solution are called equivalent equations e.g. 5 +3 = 2 + 6. And this as we learned in a previous section is shown by the equality sign =. An inverse operation are two operations that undo each other e.g. addition and subtraction or multiplication and division. You can perform the same inverse operation on each side of an equivalent equation without changing the equality.
5+3−2=6+2−2
This gives us a couple of properties that hold true for all equations.
The addition property of equality tells us that adding the same number to each side of an equation gives us an equivalent equation
ifa−b=c,thena−b+b=c+b,ora=c+b
The same goes with the subtraction property of equality.
ifa+b=c,thena+b−b=c−b,ora=c−b
As well as it goes for the multiplication property of equality. If you multiply each side of an equation with the same nonzero number you produce an equivalent equation.
ifab=c,andb≠0,thenab⋅b=c⋅b,ora=cb
And naturally this goes for the division property of equality as well. You can divide each side of an equation with the same nonzero number to produce an equivalent equation
ifa⋅b=c,andb≠0,thena⋅bb=cb,ora=cb
This gives us a way to change an equation to our own liking. Anything is acceptable as long as you do the same thing on both sides.

David car would cover one lap of the Indy 500 in about 90 seconds. Chris’s car could cover one lap in about 54 seconds. If both cars left the same starting point at the same time, after how many seconds would they meet again at the starting Point ?
Answer:
36
Step-by-step explanation:
it took David's car 90 seconds and chris's car 54 seconds so that means
90-54=36
The number of seconds would they meet again at the starting point will be 270 seconds.
What is the least common factor (LCM)?The corresponding value integer that can be divided by both is known as the lowest relevant multiple, commonly referred to as the lowest common multiple of pair (or more) numerals a and b.
David's car would cover one lap of the Indy 500 in about 90 seconds. Chris’s car could cover one lap in about 54 seconds.
If both cars left the same starting point at the same time. Then the number of seconds would they meet again at the starting point will be given as,
L.C.M. = 90, 54
L.C.M. = 2 x 3 x 3 x 5, 2 x 3 x 3 x 3
L.C.M. = 2 x 3 x 3 x 3 x 5
L.C.M. = 270 seconds
The number of seconds would they meet again at the starting point will be 270 seconds.
