what’s the value of r in 11+r=34 show work
Answer:
23
Step-by-step explanation:
This question is actually too simple
But let Me explain
First, I'd say we're looking for 'r'
So we make 'r' a constant in the equation
aND by doing so we land at this equation below
r =34-11 reason (11 is moving over to the other side) so it'll automatically become minus
then you solve
Since r =34-11 > r =23.
The value of r is:
r = 23Work/explanation:
The problem has provided us with a one-step equation, which means that it only takes one step to solve it.
To find the value of r in the given equation, I subtract 11 from each side:
\(\sf{r=34-11}\)
\(\sf{r=23}\)
Hence, r = 23GHD989 guys please you this code for guathmath thank you .

write an if statement that assigns 10000 to the variable bonus if the value of the variable goodssold is greater than 500000
The if statement assigns a value of 10000 to the variable "bonus" if the value of the variable "goodssold" exceeds 500000.
To achieve this, we can use an if statement in programming. An if statement allows us to conditionally execute a block of code based on a specified condition. In this case, the condition is whether the value of the variable "goodssold" is greater than 500000. If the condition evaluates to true, the code inside the if statement will be executed, and the variable "bonus" will be assigned a value of 10000.
Here's an example of how the if statement can be written in Python:
if goodssold > 500000:
bonus = 10000
In this code snippet, the variable "goodssold" represents the number of goods sold, and we compare its value to 500000 using the greater than operator (>). If the condition is true, the code inside the if statement is executed, and the variable "bonus" is assigned a value of 10000. If the condition is false, the code inside the if statement is skipped, and the variable "bonus" retains its previous value (if any).
By using this if statement, we can dynamically assign a bonus of 10000 to the variable "bonus" based on the value of the variable "goodssold" being greater than 500000. This allows for flexible and conditional handling of the bonus calculation in the program.

Answer:
-a^4b + b^3 - 8c^2
Step-by-step explanation:
Sum of
3a^4b-4b^3+c^2 + 6a^4b+3b^3-6c^2
= 3a^4b + 6a^4b - 4b^3 + 3b^3 + c^2 - 6c^2
= 9a^4b - b^3 - 5c^2
Sum of
6a^4b-4b^3-4c^2 + 2a^4b+4b^3+7c^
= 6a^4b + 2a^4b - 4b^3 + 4b^3 - 4c^2 + 7c^2
= 8a^4b + 3c^2
Subtract
8a^4b + 3c^2 - (9a^4b - b^3 - 5c^2)
= 8a^4b + 3c^2 - 9a^4b + b^3 + 5c^2
= 8a^4b - 9a^4b + b^3 + 3c^2 + 5c^2
= -a^4b + b^3 - 8c^2

The problem can be solved using the simplex method, and the solution can be verified using the graphical method. The optimal solution is X1 = 6, X2 = 0, X3 = 6, Z = 24.
The problem can be solved using the simplex method, and verified using the graphical method. Here are the steps:
Convert the problem to standard form by introducing slack variables:
Min Z = -2X1 - 4X2 - 3X3 + 0S1 + 0S2 + 0S3
St. X1 + 3X2 + 2X3 + S1 = 30
X1 + X2 + X3 + S2 = 24
3X1 + 5X2 + 3X3 + S3 = 60
Xi, Si >= 0
Set up the initial simplex tableau:
| 1 3 2 1 0 0 30 |
| 1 1 1 0 1 0 24 |
| 3 5 3 0 0 1 60 |
| 2 4 3 0 0 0 0 |
Identify the entering variable (most negative coefficient in the objective row): X2
Identify the leaving variable (smallest ratio of RHS to coefficient of entering variable): S1
Pivot around the intersection of the entering and leaving variables to create a new tableau:
| 0 2 1 1 -1 0 6 |
| 1 0 0 -1 2 0 18 |
| 0 0 0 5 -5 1 30 |
| 2 0 1 -2 4 0 36 |
Repeat steps 3-5 until there are no more negative coefficients in the objective row. The final tableau is:
| 0 0 0 7/5 -3/5 0 18 |
| 1 0 0 -1/5 2/5 0 6 |
| 0 0 1 1/5 -1/5 0 6 |
| 0 0 0 -2 4 0 24 |
The optimal solution is X1 = 6, X2 = 0, X3 = 6, Z = 24.
To verify the solution using the graphical method, plot the constraints on a graph and find the feasible region. The optimal solution will be at one of the corner points of the feasible region. By checking the values of the objective function at each corner point, we can verify that the optimal solution found using the simplex method is correct.
In conclusion, the problem can be solved using the simplex method, and the solution can be verified using the graphical method. The optimal solution is X1 = 6, X2 = 0, X3 = 6, Z = 24.

if a coin is flipped 10 times what is the probability of approximately 5 heads, that is, exactly 4 or 5 or 6 heads?
The probability of getting approximately 5 heads (that is, exactly 4 or 5 or 6 heads) in 10 coin flips is 0.656 or about 65.6%.
The probability of approximately 5 heads in 10 coin flips can be calculated using the binomial distribution formula. This formula states that the probability of getting exactly k successes (in this case, heads) in n independent trials (coin flips) with a probability p of success on each trial (0.5 for a fair coin) is:
P(k successes) = (n choose k) * p^k * (1-p)^(n-k)
Where "n choose k" is the binomial coefficient, which represents the number of ways to choose k items from a set of n items (in this case, the number of ways to get k heads in n coin flips).
For this problem, we want to find the probability of getting either exactly 4, 5, or 6 heads in 10 coin flips. So we need to calculate the probability of each of these outcomes separately and then add them together:
P(4 heads) = (10 choose 4) * 0.5^4 * 0.5^6 = 0.205
P(5 heads) = (10 choose 5) * 0.5^5 * 0.5^5 = 0.246
P(6 heads) = (10 choose 6) * 0.5^6 * 0.5^4 = 0.205
The total probability of approximately 5 heads is the sum of these probabilities:
P(4 or 5 or 6 heads) = P(4 heads) + P(5 heads) + P(6 heads) = 0.656

The number of stuffed bears with Su=153181
What is the number of stuffed bears Su has?Total number of bears Erin has=555555
The number of bears Erin took out=777
Remaining number of bears with Erin=555555-777

What is the Pythagorean Theorem?Pythagoras theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“. The sides of this triangle have been named Perpendicular, Base and Hypotenuse. Here, the hypotenuse is the longest side, as it is opposite to the angle 90°. The sides of a right triangle (say a, b and c) which have positive integer values, when squared, are put into an equation, also called a Pythagorean triple.
The distance in this problem is the diagonal of a rectangle, which is the hypotenuse of a right triangle in which the length and the width are the sides, hence:
d² = 85² + 120²
d = \(\sqrt{(85)^2+(120)^2}\)
d = 147.1 yards.

We want to find the height of the clock tower, which is CE. We have the angle of elevation ACD, which is 19 degrees, and the distance AB, which is 100 m. We can use tangent to find CE:
tan(ACD) = CE / AB

CE = 100 * tan(19)
CE ≈ 34.5 m (rounded to 1 decimal place)
Therefore, the height of the clock tower is approximately 34.5 m.
