Final Answer: [tex]b = -18[/tex]
Steps/Reasons/Explanation:
Question: Solve [tex]-21 = -9 + \frac{2}{3}b[/tex].
Step 1: Simplify [tex]\frac{2}{3}b[/tex] to [tex]\frac{2b}{3}[/tex].
[tex]-21 = -9 + \frac{2b}{3}[/tex]
Step 2: Regroup terms.
[tex]-21 = \frac{2b}{3} - 9[/tex]
Step 3: Add [tex]9[/tex] to both sides.
[tex]-21 + 9 = \frac{2b}{3}[/tex]
Step 4: Simplify [tex]-21 + 9[/tex] to [tex]-12[/tex].
[tex]-12 = \frac{2b}{3}[/tex]
Step 5: Multiply both sides by [tex]3[/tex].
[tex]-12[/tex] × [tex]3 = 2b[/tex]
Step 6: Simplify [tex]-12[/tex] × [tex]3[/tex] to [tex]-36[/tex].
[tex]-36 = 2b[/tex]
Step 7: Divide both sides by [tex]2[/tex].
[tex]-\frac{36}{2} = b[/tex]
Step 8: Simplify [tex]-\frac{36}{2}[/tex] to [tex]-18[/tex].
[tex]-18 = b[/tex]
Step 9: Switch sides.
[tex]b = -18[/tex]

0 6x – 27
Answer:
-9x-27+15x=6x-27
.....6x-27.…...
Answer:
D: 6x - 27
Step-by-step explanation:
1. Distribute
2. Combine like terms
3. You will get your final answer
-9(x + 3) = -9x - 27
-9(x) = -9x
-9(3) = -27
-9x - 27 + 15x
-9x and 15x are like terms. So add them
-9x + 15x = 6x
So your final answer is 6x - 27.

Write an expression in terms of x to represent the area of parallelogram PQRS
Answer:
The value of b is 5 if the parallelogram is a rectangle
Step-by-step explanation:
Mathematically, the diagonals of a rectangle are equal in value
Thus, for the given expressions to represent the diagonals of a rectangle, the two must be equal
To get the value of b that makes the two equal, we simply equate the two expressions
We have this as;
10/12(24b/5 - 36/5) = 2/3 (3b + 6)
opening the brackets, we have;
4b - 6 = 2b + 4
4b - 2b = 4 + 6
2b = 10
b = 10/2
b = 5

[tex]\text{tan}(\frac{\theta}{2})=\text{sin}\theta[/tex]
[tex]\text{tan}(\frac{\theta}{2})=2\text{sin}{\frac{\theta}{2}} \text{cos}(\frac{\theta}{2})[/tex]
[tex]\frac{\text{sin}\frac{\theta}{2}}{\text{cos}\frac{\theta}{2}} =2\text{sin}{\frac{\theta}{2}}\text{cos}(\frac{\theta}{2})[/tex]
[tex]\text{sin\frac{\theta}{2}}=2\text{sin}{\frac{\theta}{2}}\text{cos}^2(\frac{\theta}{2})[/tex][tex]\text{sin\frac{\theta}{2}}=2\text{sin}{\frac{\theta}{2}}\text{cos}^2(\frac{\theta}{2})[/tex][tex]\text{sin}\frac{\theta}{2}=2\text{sin}{(\frac{\theta}{2})}\text{cos}^2(\frac{\theta}{2})[/tex]
[tex]\text{sin}\frac{\theta}{2}-2\text{sin}{(\frac{\theta}{2})}\text{cos}^2(\frac{\theta}{2})=0[/tex]
[tex]\text{sin}\frac{\theta}{2}[1-2\text{cos}^2(\frac{\theta}{2})]=0[/tex]
[tex]\text{sin}\frac{\theta}{2}=0[/tex] ⇒ [tex]\theta=0[/tex]
[tex]1-2\text{cos}^2(\frac{\theta}{2})=0[/tex]
[tex]\text{cos}(\frac{\theta}{2})=\frac{1}{\sqrt{2}}[/tex]
[tex]\frac{\theta}{2}=\frac{\pi}{4}[/tex]
[tex]\theta=\frac{\pi}{2}[/tex]
Therefore, θ = 0 and [tex]\frac{\pi}{2}[/tex] are the solutions.

Janet buys 12 pencils
for $1.49. What is the
cost per pencil?
Answer:
About 0.12 dollars
Step-by-step explanation:
1.49/12 = 0.12416666666/1
About 0.12 dollars
Answer:
0•1254$ per pencil
Step-by-step explanation:
method 1
12 pencils = 1•49$
1 pencil = X ( unknown)
cross multiply
12x = 1•49$
divide both sides by 12x
X = 0•124$ per pencil
Method 2
you can simply divide the price of the pencils = 1•49$
by the number of pencils bought = 12
1•49/12
= 0•124$
The stock market dropped 220 points on Monday. It lost another 48 points on Tuesday, and on Wednesday, it gained 96 points. What was the amount of change over those three days.
Request you to finish this please
48 points gained in those 3 days.
Subtract 220 with 48, then add 96. Last step would be subtracting 220 with the amount they have now in those 3 days to find how much points the stock market gained in those 3 days.
Subtract 220-48.It‘ll be 172.
Add 172 with 96. 172+96=268.
Subtract 268 with how much points the stock market had 3 days ago. 268-220.
Sot eh stock market gained 48 points in 3 days.

The value of x is 20.
What are trigonometric identities?There are three commonly used trigonometric identities.
Sin x = Perpendicular / Hypotenuse
Cosec = Hypotenuse / Perpendicular
Cos x = Base / Hypotenuse
Sec x = Hypotenuse / Base
Tan x = Perpendicular / Base
Cot x = Base / Perpendicular
We have,
Sin 30 = 10 / x ______(10
We know that,
Sin 30 = 1/2 _____(2)
So,
Substituting (2) in (1).
1/2 = 10/x
x = 10 x 2
x = 20
Thus,
The value of x is 20.

Schuyler spent $208 on a sewing machine to make purses. They spend a total of $10 on thread, fabric, and accessories for each purse and plans to charge $36 for each purse. The system below represents this situation. 208 + 10x = y 36x = y How many purses must they sell in order to break even? Blank 1:
Answer:
The answer is 8 purses
Step-by-step explanation:
If we multiply 36 by 8, we get $288. If we multiplied 36 by 8 we must also multiply 10 by 8 because it cost 10 dollars on one purse. So y=10(8)+208, y=288

The number of bacterial colonies of a certain type in samples of polluted water has a Poisson distribution with a mean of 3 per cubic centimeter (cm3). (a) If five 1 cm3 samples are independently selected from this water, find the probability that at least one sample will contain one or more bacterial colonies. (Round your answer to four decimal places.)
Answer:
[tex]P(X\geq 1)= 1 - 0.0497 8 =0.95022[/tex]
Step-by-step explanation:
Step(i):-
Let 'X' be the random variable in Poisson distribution
Mean of the Poisson distribution λ or ∝ = 3 per (cm³)
Given n = 5 samples
[tex]P(X=r) = \frac{e^{-\alpha }\alpha ^{r} }{r!}[/tex]
Step(ii):-
The probability that at least one sample will contain one or more bacterial colonies
P(X≥1) = 1-P(X< 1)
= 1 - P( X=0)
[tex]P(X\geq 1)= 1 - \frac{e^{-\alpha }\alpha ^{r} }{r!}[/tex]
[tex]P(X\geq 1)= 1 - \frac{e^{-3 }3 ^{0} }{0!}[/tex]
[tex]P(X\geq 1)= 1 - 0.0497 8 =0.95022[/tex]
