Answer:
196 tickets
Step-by-step explanation:
The total expenses to put on a 3-day production of a play is $980. Each ticket to go and watch the play is going to be sold for $5. The producer sells x number of tickets, x number of tickets would cost 5x. Therefore to find the number of tickets the producer must sell so as to make a profit the money generated from selling the tickets must be more than the cost of production. Therefore we use the formula:
5x ≥ 980
Dividing through by 5:
x ≥ 980
x ≥ 980/5
x ≥ 196
Therefore the producer must sell at least 196 tickets so as to make a profit
Can somebody please help me!!
Step-by-step explanation:
Simply you replace X and Y by their values
Given: x=-1 y=-4
10 - (-X)^3 + y^2
=10 + X^3 + Y^2
Now replace X and Y
=10 + (-1)^3 + (-4)^2
=10 - 1 + 16
= 25

Which ordered pair is a solution if the equation? 2x + 3y = 10
Answer:
See below.
Step-by-step explanation:
Try each ordered pair in the equation. Each ordered pair is of the form (x, y). Replace x and y in the equation by values of x and y, respectively, in each ordered pair. Whichever ordered pair makes the equation a true statement is the answer.
For example:
Try (2, 3):
2x + 3y = 10
2(2) + 3(3) = 10
4 + 9 = 10
13 = 10
Since 13 = 10 is a false statement, (2, 3) is not a solution.
Try (2, 2):
2x + 3y = 10
2(2) + 3(2) = 10
4 + 6 = 10
10 = 10
Since 10 = 10 is a true statement, (2, 2) is a solution.
Subtract: 2 square root -8 -3 square root -18
Answer:
[tex] - 5 \sqrt{ - 2} [/tex]
Step-by-step explanation:
We can write sq root (- 18) as = sq root [3 x 3 x (-2)]
Similarly sq root ( - 8) = sq root [2 x 2 x (-2)]
2 sq root [2 x 2 x (-2)] - 3 sq root [3 x 3 x(-2)]
We simply,
2 x2 sq root (-2) - 3 x 3 sq root (-3)
4 sq root (-2) - 9 sq root (-2)
Bcoz sq root (-2) is common in bot term so
So
Sq root (-2) (4-9)
-5 sq root (-2) answer

Identify the equation which has no solution. 3x - 21 = 3(x + 7) 3x - 21 = 3(x - 7) 3x - 21 = x - 7 All of the choices
Answer:
3x - 21 = 3(x + 7).
Step-by-step explanation:
3x - 21 = 3(x + 7)
3x - 21 = 3x + 21
3x - 3x = 21 + 21
0 = 42
Since the two are not equal, this equation has no solution.
3x - 21 = 3(x - 7)
3x - 21 = 3x - 21
3x - 3x = -21 + 21
0 = 0
Since the two are equal, this equation has infinitely many solutions.
3x - 21 = x - 7
2x = 14
x = 7
This equation has one solution.
Since there is only one choice that makes sense, the answer won't be all of the choices.
The answer is A. 3x - 21 = 3(x + 7).

Given: Q = 7m + 3n, R = 11 - 2m, S = n + 5, and T = -m - 3n + 8.
Simplify [Q - R] + [S - T].
10m - 7n - 14
10m + 5n - 24
10m - 5n + 24
10m + 7n - 14
Answer:
The answer is 10m + 7n - 14
Step-by-step explanation:
Q = 7m + 3n
R = 11 - 2m
S = n + 5
T = -m - 3n + 8
[Q - R] + [S - T] is
[ 7m + 3n - (11 - 2m) ] + [ n + 5 - ( - m - 3n+8)]
Solve the terms in the bracket first
That's
( 7m + 3n - 11 + 2m ) + ( n + 5 + m + 3n - 8)
( 9m + 3n - 11 ) + ( m + 4n - 3)
Remove the brackets
That's
9m + 3n - 11 + m + 4n - 3
Group like terms
9m + m + 3n + 4n - 11 - 3
The final answer is
10m + 7n - 14Hope this helps you

Justin earned scores of 85, 92, and 95 on his science tests. What does he need
to earn on his next science test to have an average (arithmetic mean) of 93%?
Answer:
Justine needs to score a 100 to have an average of 93%.
Step-by-step explanation:
Given:
Justin scores 85, 92 and 95 on his science tests.
To find:
The score that he needs to earn to have an average of 93%?
Solution:
Let the score in next science test = [tex]x[/tex]
Formula for Average/Arithmetic Mean is given as:
[tex]Average = \dfrac{\text{Sum of all observations}}{\text{Total number of observations}}[/tex]
Here we have 4 number of total observations and average is 93%.
Now, put all the values here:
[tex]93 = \dfrac{85 +92+ 95+x}{4}\\\Rightarrow 93\times 4=85 +92+ 95+x\\\Rightarrow 372=272+x\\\Rightarrow x = 372-272\\\Rightarrow x = 100[/tex]
So, Justin needs to score 100 to have an average of 93%.
What is the slope of the line given by the equation y=-3X?
A. 1/3
B. -1/3
C. -3
D. 3
Answer:
[tex]\boxed{-3}[/tex]
Step-by-step explanation:
The slope-intercept form of an equation is determined by the constant equation [tex]y=mx+b[/tex] where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept of the line.
Therefore, we can use the equation given and implement it to find your slope.
[tex]y=-3x[/tex]
Our equation does not have a y-intercept, [tex]b[/tex]. Therefore, it can just be inferred as [tex]+0[/tex].
Because we do have a [tex]m[/tex], we can then find out what our slope is: [tex]\boxed{-3}[/tex].

If events A and B are non-overlapping events, how do you find the probability that one or the other occurs?
The probability of two non-overlapping events A or B happening is:
p(A or B) = p(A) + p(B)
if you add an image of the question you are trying to answer, I can explain it better.
Answer:
If events A and B are non-overlapping events.
P(A or B) = P(A) + P(B)
To find the probability that one or the other occurs, you add the probability of both events occurring together.

Answer:
The circumference of circle is 14π cm.
Step-by-step explanation:
Given that the formula of circumference is C = 2×π×r where r represents radius of circle. In this case, diameter of circle is 14cm so the radius will be 7cm. Then, you have to substitute the value into the formula :
[tex]c = 2 \times \pi \times r[/tex]
[tex]let \: r = 7[/tex]
[tex]c = 2 \times \pi \times 7[/tex]
[tex]c = 14\pi \: \: cm[/tex]
Answer:
14[tex]\pi[/tex]
units = cm
Step-by-step explanation:
circumference = 2 x [tex]\pi[/tex] x r
c = 2 x [tex]\pi[/tex] x 7 - it's 7 because the diameter is 14 and radius is half the diameter
c = 14 x [tex]\pi[/tex]
c = 43.98229715
in terms of pi c = 14 [tex]\pi[/tex]
units = cm

Answer:
192.154 ft²
Step-by-step explanation:
Area of a Hexagon Formula: A = 3√3/2(x)²
x is the side of the hexagon. We simply plug in 8.6 in for x:
A = 3√3/2(8.6)²
A = 3√3/2(73.96)
A = 221.88√3/2
A = 110.94√3
A = 192.154
Answer:
~192.2
Step-by-step explanation:
The area of a regular hexagon is calculated by:
A = [3*sqrt(3)/2]x side x side = 3*sqrt(3)/2 x 8.6^2 = ~192.2
Graph the first six terms of a sequence where a1 = 3 and d = −10.
Answer:
Step-by-step explanation:
nth term = (n-1)th term + common difference
d = -10
a₁ = 3
a₂ = a₁ + d = 3 + (-10) = -7
a₃ = a₂ + d = -7 + (-10) = -17
a₄ = a₃ + d = -17 + (-10) = -27
a₅ =a₄ + d = -27 + (-10) = -37
a₆ = a₅ + d = -37 + (-10) = -47
First six terms: 3 , -7 , -17, -27, -37 , -47
Find the coefficient of fourth term of (-x -3)^5
Answer:
-270
Step-by-step explanation:
Here, we want to know the coefficient of the fourth term.
The coefficients according to pascal triangle for the expansion is 1 5 10 10 5 1
So the expansion looks as follows;
1[(-x)^5(-3)^0] + 5[(-x)^4(-3)^1)] + 10[(-x)^3(-3)^2) + 10[(-x)^2(-3)^3] + ...........
So the fourth term we are dealing with is
10[(-x)^2(-3)^3)]
So the value here is
10 * x^2 * -27
= -270 x^2
So the coefficient is -270
How many 9-digit palindromes are there with all the digits being even and each digit appearing no more than twice?
Answer: 96
Step-by-step explanation:
A palindrome is a number that is the same when reading in both ways (right to left, and left to right), for example, 121
Then, we have 9 digits, and all the digits need to be even.
the options are: 0, 2, 4, 6, 8.
Now, we can tink a 9 digit number as 9 empty slots, and in each slot, we can put a number.
But because this is a palindrome, the first digit must be equal to the ninth, and the second digit must be equal to the eight, and so on.
So we can tink it as actually only 5 slots, where in each slot, we can put an even number, now let's count the options that we have in each selection.
For the first digit we have 4 options: 2, 4, 6 and 8 (0 is not counted here because if the first digit was a 0, then this would not be a 9 digit number).
for the second digit, we have also 4 options (because we already toked one, but now the 0 can be chosen)
for the third digit, we have 3 options
for the fourth digit, we have 2 options
for the fifth digit, we have only one option.
The total number of combinations is equal to the product of the number of options for each selection:
C = 4*4*3*2*1 = 96

96

Answer:
We have 2 rational solutions
0 irrational solutions
0 complex solutions
Step-by-step explanation:
a^2 + 8a + 12 = 0
Using the discriminant
b^2 -4ac where ax^2 + bx+ c
so a =1 b = 8 and c = 12
8^2 -4(1)*12
64 - 48
16
Since the discriminant is greater than 0, we have 2 real solutions
since we can take the square root of 16, we have rational solutions
We have 2 rational solutions
Since this is a quadratic equations, there are only 2 solutions so there are
0 irrational solutions
0 complex solutions
Answer:
2 Rational Solutions
0 Irrational Solutions
0 Complex Solutions
Step-by-step explanation:
The discriminant of the quadratic formula is the name given to the portion underneath the radical (or the square root)"
[tex]x = \frac{1}{2} (-b\frac{ + }{ - } \sqrt{ {b}^{2} - 4ac })[/tex]
Discriminant = D = b²-4ac
If D is less than 0 you have two complex solutions.
If D is equal to 0 you'll have one real solution.
If D is bigger than 0 you'll get two real solutions.
So here we have:
a=1
b=8
c=12
Which means D=64-4(1)(12)=64-48=16>0
D is bigger than 0, so you'll have two real solutions. And since 16 is a perfect square, they'll both be rational numbers.
