If ∠P measures 27°, ∠R measures 135°, and p equals 9.5, then which length can be found using the Law of Sines?
Answer:
r = 14,8
Step-by-step explanation:
Hope you can read my writing ;-)
The length that can be found using the Law of Sine rule is
r= 14.80 units
What is the lenght?Generally,
Generally, the equation for sin rule is mathematically given as
[tex]\frac{p}{sinP} = \frac{q}{sinQ} = \frac{r}{sinR}[/tex]
Where
p = 9.5 units
∠P = 27°
∠R = 135°
Therefore
[tex]\frac{9.5}{sin 27^0} = \frac{q}{sin Q} = \frac{r}{sin 135^0}[/tex]
[tex]\frac{9.5}{sin 27^0} = \frac{r}{sin 135^0}[/tex]
9.5 x 0.7071 = r x 0.4540
r = 14.80 units

Yuson used her calculator to solve the equation x-
- 8 = 3. She entered the following on her screen and got an incorrect answer. How
could she use parentheses to find the correct answer? Explain. What is the correct answer?
Answer:
[tex]x - (-8) = 3[/tex]
[tex]x = -5[/tex]
Step-by-step explanation:
Equation
[tex]x - -8 = 3[/tex]
Solving (a): Using Parenthesis
The equation can be rewritten by putting -8 in a parenthesis as follows;
[tex]x - (-8) = 3[/tex]
Solving (b): The correct answer
[tex]x - (-8) = 3[/tex]
Start by opening the bracket
[tex]x + 8 = 3[/tex]
Subtract 8 from both sides
[tex]x + 8 - 8 = 3 - 8[/tex]
[tex]x = 3 - 8[/tex]
[tex]x = -5[/tex]
Hence, the correct solution is [tex]x = -5[/tex]

5x+7+3x=-8+3x please solve it before 8:30
Answer:
x=-3
Step-by-step explanation:
5x+7+3x=-8+3x
Combine like terms
8x+7 = 3x-8
Subtract 3x from each side
8x+7-3x = 3x-8-3x
5x+7 = -8
Subtract 7 from each side
5x+7-7 = -8-7
5x = -15
Divide each side by 5
5x/5 = -15/5
x = -3
For each problem, find the missing value using the Pythagorean Theorem
Answer: [tex]\sqrt{66}[/tex]
Step-by-step explanation:
The Pythagorean Theorem says that a^2 + b^2 = c^2 where a and b are the two legs.
In this care leg 1 is 4 and leg two is the square root of 50. So we will square them to find c which is the hypotenuse.
4^2 + [tex]\sqrt{50} ^2[/tex] = C^2
16 + 50 = c^2
66 = c^2
c =[tex]\sqrt{66}[/tex]
The fox population in a certain region has a continuous growth rate of 5% per year. It is estimated that the population in the year 2000 was 10,100 foxes.
a) Find a function that models the population,P(t) , after (t) years since year 2000 (i.e. t= 0 for the year 2000).
b) Use your function from part (a) to estimate the fox population in the year 2008.
c) Use your function to estimate the year when the fox population will reach over 18,400 foxes. Round t to the nearest whole year, then state the year.
Answer:
P(t) = I × ( 1 +g)^t
14922
2013
Step-by-step explanation:
Given the following :
Growth rate (g) = 5% = 0.05
Initial population (I) = 10,100
Time (t) = t (t = 0 in year 2000)
A) population function P(t)
P(t) = I × ( 1 +g)^t
P(t) population in t years
I = inital population
g = growth rate
t = years after year 2000
B) Population Estimate in year 2008
2008 - 2000 = 8 = t
P(8) = 10,100 × ( 1 +0.05)^8
P(8) = 10,100 × (1.05)^8
P(8) = 10,100 × 1.4774554437
P(8) = 14922.299 = 14922
C.) Nearest whole year when population will reach over 18,400
18,400 = 10,100 × ( 1 +0.05)^t
18400 = 10,100(1.05)^t
1.05^t = 18400 / 10,100
1.05^t = 1.8217821
In(1.05^t) = ln(1.8217821)
(0.0487901)t = 0.5998152
t = 0.5998152 / 0.0487901
t = 12.293789
To attain a population of 18400 and over, the nearest whole year = 13 years
2000 + 13 = 2013

Answer:
x = 0
Step-by-step explanation:
First, distribute the -4 to the parentheses:
-4 + 3x = 2x - 4(1 - 3x)
-4 + 3x = 2x - 4 + 12x
Then, add like terms:
-4 + 3x = 14x - 4
Solve for x:
3x = 14x
0 = 11x
0 = x
Answer:
x=0
Step-by-step explanation:
We are given the following equation and asked to solve. We must solve for x by isolating x on one side of the equation.
-4 + 3x= 2x-4(1-3x)
First, distribute the -4. Multiply each term inside the parentheses by -4.
-4+3x=2x + (-4*1) + (-4*-3x)
-4+3x= 2x -4 + (-4*-3x)
-4+3x= 2x-4+12x
Combine like terms on the right side of the equation. The terms 2x and 12x can be added.
-4+3x= (12x+2x)-4
-4+3x=14x-4
Next, subtract 3x to both sides of the equation.
-4+3x-3x=14x-3x-4
-4= (14x-3x)-4
-4= 11x-4
Next, add 4 to both sides of the equation.
-4+4=11x-4+4
-4+4=11x
0=11x
Finally, divide both sides of the equation by 11.
0/11= 11x/11
0/11=x
0=x
The solution to the equation -4 + 3x= 2x-4(1-3x) is x=0

Rayée sold 3 desks at the local trade show. H paid $4.00 to rent the booth. He gave half of his revenue to the carpenter and was left with $185.50. At what price did he Rayen sell with each desk
Answer:
$125
Step-by-step explanation:
Given the following :
Number of desks sold = 3
Amount of rent paid = $4
Amount paid to carpenter = 1/2 of revenue
Amount left = $185.50
At what price did Ryan sell each desk?
If Rayee gave half of his revenue to the carpenter and then had $185.50 left,
The his revenue before paying the carpenter will be twice what he has left ($185.50 * 2) = $371
Hence, total revenue from the sale of 3 desk= ($371 + rent) = (371 + 4) = $375
Then each desk cost :
$375 / 3 = 125
$125

Short Response 16. Parallel lines p and q are cut by transversal t to form angles 1-8. If 22 and 27 are alter- nate exterior angles, 27 and 26 are vertical angles, and 26 and 24 are consecutive interior angles, what can you conclude about the relationship between the angle measures of 22 and 24? Explain.
I don’t understand how to solve this, please help!!
Answer:
see below (I hope this helps!)
Step-by-step explanation:
Alternate exterior angles are congruent so we know that ∠2 ≅ ∠ 7. Vertical angles are also congruent so ∠7 ≅ ∠6. Consecutive interior angles are supplementary so we know that ∠6 and ∠4 are supplementary. Now, we can use the Transitive Property (this states that if a = b and b = c then a = c) to compare ∠2 and ∠4. In this case, a = ∠2, b = ∠7 and c = ∠6 so we know that ∠2 ≅ ∠6 and since ∠6 is supplementary to ∠4, we can use the Transitive Property again to conclude that ∠2 and ∠4 are supplementary.

Write the expression in exponential form.
[tex] \sqrt{10} [/tex]
When we use an exponent of 1/2, it is the same as a square root. The more general rule is
[tex]\sqrt{x} = x^{1/2}[/tex]
In this case, we plug in x = 10.
The use of a fractional exponent is handy when you want to deal with things like cube roots on a calculator. This is because
[tex]\sqrt[3]{x} = x^{1/3}[/tex]
Many calculators don't have a button labeled [tex]\sqrt[3]{}[/tex] but they have the button [tex]x^y[/tex] to allow fractional exponents.

The area of a rectangle is 560 cm^2. The length is 3 more than twice the width. Find the dimensions of the rectangle.
Let the width be x.
Then,length = 2x + 3
Area of rectangle = 560 [ Given ]
⇒ l × b = 560
⇒ ( 2x + 3 ) x = 560
⇒ 2x² + 3x - 560 = 0
⇒ 2x² + 35x - 32x - 560 = 0
⇒ x ( 2x + 35 ) - 16 ( 2x + 35 ) = 0
⇒ ( x - 16 ) = 0 and ( 2x + 35 ) = 0
⇒ x = 16 and x = -35/2 [ Ignore negative number ]
★ Width = x = 16 cm
★ Length = 2x + 3 = 2 × 16 + 3 = 32 + 3 = 35 cm
Austin prepared 20 kilograms of dough after working 5 hours. How many hours did Austin work if he prepared 36 kilograms of dough? Assume the relationship is directly proportional.
Answer: 9 hours
If austin prepared 20 kg of dough in 5 hours, this means he can prepare 4kg of dough an hour. This is because 20/5=4. Knowing this information, it would only make sense that Austin worked for 9 hours to prepare 36 kg of dough.

Which expression is equivalent to (3^4 • 5^4)^-3
A. 1/15^3
B. 15^-48
C. 1/15^12
D. 15^5
Tania chose B as the correct answer, How did she get that?
3^4*5^4 = (3*5)^4 = 15^4
Raise this to the exponent -3 and we get
(3^4*5^4)^(-3) = (15^4)^(-3) = 15^(4*(-3)) = 15^(-12)
The last step is to use the rule
x^(-k) = 1/( x^k )
So,
15^(-12) = 1/( 15^12 )
The answer is actually choice CIt seems like Tania multiplied all the exponents to get 4*4*(-3) = 16*(-3) = -48, but you only multiply the inner and outer exponents together as I did when I went from (15^4)^(-3) to 15^(-12)
The quotient below is shown without the decimal point. Use number sense to place the decimal point correctly. 370 ÷ 2.5 ÷ 1.6 = 925
Answer:
92.5
Step-by-step explanation:
When you would look at this you would just see that there are if you divide 370 by 2 and 2 again you will not get a small number so the only logical answer is 92.5
The number would be 92.5
First, we have to convert decimal to fraction
370/(25/10 * 16/10)
now, reduce the expression to the lowest term
370/4
reduce the fraction
185/2
=92.5
