Answer:
B
Step-by-step explanation:
28/4=7 therefore, each ticket is $7.
Answer:
B, C
Step-by-step explanation:
A is wrong due to the fact that if you divide $28 into 4 (family of 4), the cost is $7 per ticket. If you add 2 tickets together, or multiply $7 by 2, you get $14.
B is right due to the fact that each ticket is $7 if you divide $28 by 4.
C is right due to the fact that if you have 6 tickets worth $7 each, it would mean that the total cost of 6 tickets would be $42. (6*7 = 42)
D is wrong due to the fact that if you multiply 7 (the cost of each ticket) by 12, it gets you 84, not 60.

drove 540 miles in 8 hours,
Who drove faster? Explain your answer.
please help it’s for 21 points
Answer:
katelyn
Step-by-step explanation:
you divide distance by time to get rate, and katelyn has a faster rate because 210/3 is more than 540/8
Answer:
Katelyn drove faster
t=d/s
s=d/t
d=s*t
Step-by-step explanation:
s=d/t is what we are using to find the speed
Katelyn- 210/3=70
Samantha-540/8=67.5

7. The daily cost of production in a video game factory is calculated using c(x) = 400 + 25x, where x is
the number of complete video games manufactured. Which set of numbers best defines the domain of c(x)?
(1) integers
(2)positive real numbers
(3) positive rational numbers
(4)whole numbers
Answer:
(4) whole numbersStep-by-step explanation:
Given function:
c(x) = 400 + 25xwhere x is the number of complete video games.The complete video games can be expressed as positive integers or whole numbers, so the domain is whole numbers.
Correct choice is (4)
Answer:
Whole Number
Explanation:
Domain : The set of all the input values (i.e. the value of x ) in the function is called domain
The daily cost of production in a video game factory is calculated using c(x) = 400 + 25x
Cost expression : C(x) = 400 + 25x
Cost expression : C(x) = 400 + 25x
As x defines the number of complete video, since number of video cannot be negative.
1) Integers : integers are the numbers which can be positive, negative or zero, but cannot be a fraction
As, number of videos cannot be negative
so, x cannot be any integers
So, Integers is not the domain
2) Positive real numbers : Real numbers are the numbers which include both rational and irrational numbers.
As the x represent the complete number of video games, thus, x cannot be irrational
Hence, Positive real numbers is not the domain
3) Positive Rational Number : a number is expressed in the form of p/q then it is a rational number
The number of videos are in the complete number, so a fraction cannot be a complete number, thus, rational number cannot be a domain.
4) Whole Number : Whole numbers include natural numbers that begin from 1 onwards
As Numbers of videos are the complete number, and they are always positive, which is the defination of whole number, Domain is whole number

Helloooooooooooooo
A new pain reliever is advertised as being 97%
effective. To 3 decimal places, what is the
probability that the pain reliever will be effective
in 12 independent trials?
A. 0.116
B. 0.694
C. 0.970
D. 0.847
Answer:
B. 0.694
Step-by-step explanation:
Probability is the ratio of the number of possible outcome to the number of total outcome.
Given that the pain reliever is advertised as being 97% effective, for it to be effective in 12 independent trials
= (97%) ^ 12
= 0.693842361
The is approximately 0.694 to 3 decimal places

Answer:

21: 70
Step-by-step explanation:
Circle upper left
The central angles all add up to 360 degrees
BC + CD + 148 = 360
But CD = BC
2BC + 148 = 360 Subtract 148 from both sides
2BC = 360 - 148 Combine
2BC = 212 Divide by 2
BC = 106

3 of the 5 arcs are marked as being equal.
Let each of them be called = x
3x + 41 + 82 = 360 Combine
3x + 123 = 360 Subtract 123 from Both sides.
3x = 360 - 123
3x = 237
x = 237 / 3
x = 79
BC = 79

Unless DE and FC are diameters, this can't be solved. I will assume they are.
FB + 48 + 22 = 180.
FB + 70 = 180
FB = 110
===========
FC = FB + BD + DC
180 = 110 + 22 + DC
180 = 132 + DC
DC = 180 - 132
DC = 48
===========
BC = BD + DC
BC = 22 + 48
BC = 70
Factor the trinomial 3x2 + 13x − 10 by grouping.
Answer:
(3x - 2) (x+5)
Step-by-step explanation:
3x^2 + 13 - 10
15× - 2 = -30
15+-2 = 13.....substitute 15x - 2x in place of 13x
3x^2+15x-2x-10
Factorise the first two values, thrn the second two
3x (x+5) - 2 (x+5)
Gathering the like terms together you eill be left with the following
(3x - 2) (x+5)
The factors of the trinomial 3x² + 13x - 10 is (3x-2)(x+5).
What is Factorization?The breaking or decomposition of an entity (such as a number, a matrix, or a polynomial) into a product of another entity, or factors, whose multiplication results in the original number, matrix, etc., is known as factorization or factoring in mathematics.
we have,
Trinomial= 3x² + 13x - 10
Now, factories using splitting the middle term we get
3x² + 13x - 10
= 3x² + 15x - 2x - 10
= 3x( x +5) - 2(x+ 5)
= (3x - 2) (x+ 5)
So, the factors are (3x- 2(x+5)

Answer:
Vertex: (-1, 4)
Maximum: f(-1) = 4
Increasing: (-∞, -1)
Decreasing: (-1, ∞)
Step-by-step explanation:
The equation can be written in vertex form by "completing the square."
First factor out the leading coefficient from the x-terms.
f(x) = -(x² +2x) +3
Then add the square of half the x-coefficient inside parentheses. Add the opposite of that amount outside parentheses.
f(x) = -(x² +2x +1) +3 +1
Write in vertex form.
f(x) = -(x +1)² +4 . . . . . . . compare to a(x -h)² +k
You can see that the vertex is (h, k) = (-1, 4), and that the vertical scale factor 'a' is negative. This means the vertex is the maximum and the parabola opens downward.
The function will be increasing to the left of the maximum, decreasing to its right.

Vertex: (-1, 4)
Maximum: f(-1) = 4
Increasing: (-∞, -1)
