What Is two thirds of a straight angle
Answers
so 2/3 of a straight angle is 2/3 of 180..." of " means multiply
2/3(180) = 360/3 = 120 <==
Two thirds of a straight angle is calculated as 120 degrees.
Two thirds of a straight angle can be calculated by first understanding that a straight angle is equal to 180 degrees. When we want to find a fraction of a given angle, we multiply the fraction by the total degree measure of that angle.
In this case, to find two thirds of a straight angle, we multiply 180 degrees by 2/3.
Here is a step-by-step explanation of the calculation:
Understand that a straight angle equals 180 degrees.
Multiply 180 degrees by the fraction 2/3:
(180 degrees) * (2/3) = 120 degrees.

The yard behind the Cindy’s house is rectangular in shape
and has a perimeter of 72 feet. If the length of the yard
is 18 feet longer than the width w of the yard, what is the
area of the yard, in square feet?
Answers
Width = x
Perimeter = 72
72 = 2(x + 18) + 2x
72 = 2x + 36 + 2x
72 = 4x + 36
72 - 36 = 4x
36 = 4x
36/4 = x
9 = x
The width is 9 feet.
The length is 9 + 18 or 27 feet.
Area = length • width
A = 27(9)
A = 243 ft^2

A campground has cabins that can each hold 28 campers. There are 148 campers that are visiting the campground. How many cabins are full if there are 28 campers in each cabin? Please help i'm desperate and i'm marking most brainliest.
Answers
To find the number of full cabins, divide the total number of campers by the number of campers in each cabin. Round the answer up to the nearest whole number.
Explanation:To find the number of full cabins, you can divide the total number of campers by the number of campers in each cabin.
148 campers / 28 campers per cabin = 5.2857 cabins
Since we can't have fractional cabins, we round up to the nearest whole number, which is 6.
Therefore, there are that are full.
Final answer:
There are 6 cabins that are full.
Explanation:
To find the number of cabins that are full, we need to divide the total number of campers by the number of campers each cabin can hold. In this case, there are 148 campers and each cabin can hold 28 campers.
We can solve this problem by dividing 148 by 28: 148 ÷ 28 = 5.2857.
Since we cannot have a fraction of a cabin, we round up to the nearest whole number. Therefore, there are 6 cabins that are full.

The owner of a candy store wants to mix some peanuts worth $3 per pound, some cashews worth $10 per pound, and some Brazil nuts worth $9 per pound to get 50 pounds of a mixture that will sell for $6.80 per pound. She uses 10 fewer pounds of cashews than peanuts. How many pounds of each did she use?
Answers
x = pounds of peanuts
y = pounds of cashews
z = pounds of Brazil nuts.
The total pounds is 50, therefore
x + y + z = 50 (1)
The total cost is $6.60 per pound for 50 pounds of mixture.
The total is equal to the sum of the costs of the different nuts.
Because the cost for peanuts, cashews, and Brazil nuts are $3, $10, and $9 respectively, therefore
3x + 10y + 9z = 50*6.8
3x + 10y + 9z = 340 (2)
There are 10 fewer pounds of cashews than peanuts, therefore
x = y + 10 (3)
Substitute (3) into (1) and (2).
y + 10 + y + z = 50
2y + z = 40 (4)
3(y + 10) + 10y + 9z = 340
13y + 9z = 310 (5)
From (4),
z = 40 - 2y (6)
Substitute (6) into (5).
13y + 9(40 - 2y) = 310
-5y = -50
y = 10
z = 40 - 2y = 40 - 20 = 20
x = y + 10 = 20
Answer:
Peanuts: 20 pounds
Cashews: 10 pounds
Brazil nuts: 20 pounds
• capital one is advertising a 60-month, 5.99% apr motorcycle loan. if you need to borrow $8000 to purchase your dream harley davidson, what will your monthly payment be?
Answers
P = $8000, the principal
r = 5.99% = 0.0599, the interest rate
t = 60 months = 5 years, the duration
Assume n = 12, monthly compounding.
n*t = 12*5 = 60
r/n = 0.0599/12 = 0.004992
The total value of the loan is
A = P(1 + r/n)⁶⁰
= 8000(1.004992)⁶⁰
= 10785.434
Monthly payment = 10785.434/60 = $179.76
Answer: $179.46
Answer:
The monthly payment is $ 154.29
Step-by-step explanation:
Given : time period = 60 months
Annual interest rate = 5.99%
Amount to be borrowed = $8000
We have to calculate the monthly payment.
We know ,
[tex]P=\dfrac{A\cdot \frac{i}{12}}{1-(1+\frac{i}{12})^{-n}}[/tex]
We have,
interest rate = 5.99% = 0.0599
Amount = $8000
time period = 60 months
P is monthly payment.
[tex]P=\dfrac{8000\left(\frac{0.059}{12}\right)}{1-\left(1+\frac{0.059}{12}\right)^{\left(-60\right)}}[/tex]
Simplify, we get,
P = 154.29
Thus, the monthly payment is $ 154.29

Calc find the maximum of f(x, y) = y2 + xy â x2 on the square 0 ⤠x ⤠6, 0 ⤠y ⤠6.
Answers
[tex]\begin{cases}f_x=y-2x=0\\f_y=2y+x=0\end{cases}[/tex]
[tex]y=2x\implies 2y+x=4x+x=0\implies x=0\implies y=0[/tex]
so on this region, [tex]f(x,y)[/tex] has only one critical point at (0, 0)[/tex]. Since this point lies on the boundary, we can ignore it for the moment.
Along the boundaries, we have four scenarios to consider:
[tex]x=0\implies f(0,y)=y^2[/tex]
[tex]x=6\implies f(6,y)=y^2+6y-36=(y+3)^2-45[/tex]
[tex]y=0\implies f(x,0)=-x^2[/tex]
[tex]y=6\implies f(x,6)=36+6x-x^2=-(x^2-6x-36)=45-(x-3)^2[/tex]
In the first case, [tex]y^2[/tex] is increasing over [tex]0\le y\le6[/tex], so we'll attain when [tex]y=6[/tex] a value of [tex]f(0,6)=36[/tex].
In the second case, [tex](y+3)^2-45[/tex] attains a minimum when [tex]y=-3[/tex], and would be increasing to either side. This would mean at [tex]y=6[/tex] we get [tex]f(6,6)=36[/tex].
In the third case, [tex]-x^2[/tex] attains a max at [tex]x=0[/tex], which would yield [tex]f(0,0)=0[/tex].
In the fourth case, [tex]45-(x-3)^2[/tex] attains a max at [tex]x=3[/tex], giving a value of [tex]f(3,6)=45[/tex].
This means the absolute maximum of [tex]f(x,y)[/tex] over the square is attained along the boundary [tex]y=6[/tex] when [tex]x=3[/tex], with a maximum value of [tex]f(3,6)=45[/tex].
To find the maximum of the function f(x, y) = y² + xy – x² on the square 0 ≤ x ≤ 6, 0 ≤ y ≤ 6, we need to find the critical points by taking the partial derivatives with respect to x and y.
To find the maximum of the function f(x, y), we need to find the critical points by taking the partial derivatives with respect to x and y:
[tex]f_x[/tex] = y - 2x
[tex]f_y[/tex] = 2y + x
Setting these derivatives equal to zero and solving for x and y, we get the critical point (2,2). To determine if this point is a maximum, minimum, or point of inflection, we can use the second derivative test. Taking the second partial derivatives:
[tex]f_{xx[/tex] = -2, [tex]f_{yy[/tex] = 2, [tex]f_{xy[/tex] = 1
Using the discriminant D = [tex]f_{xx} \times f_{yy} - {(f_{xy})}^2[/tex], we have D = [tex](-2) \times 2 - {1}^2[/tex] = -4. Since D is negative, the critical point (2,2) is a saddle point, which means there is no maximum or minimum on the given square.

The table below represents the displacement of a bird from its nest as a function of time: Time (hours) x Displacement from nest (miles) y 0 12 1 20 2 28 3 36 4 44 Part A: What is the y-intercept of the function, and what does this tell you about the bird? (4 points) Part B: Calculate the average rate of change of the function represented by the table between x = 1 to x = 3 hours, and tell what the average rate represents. (4 points) Part C: What would be the domain of the function if the bird continued to fly at this rate until it traveled 172 miles from the nest? (2 points)
Answers
Part B: Find the average rate of change: 36 - 20/2 = 16/2 = 8 mph
This tells us that the bird can travel long distances.
Part C: 172 - 12 = 160 miles at a rate of 8 mph
160 mi ÷ 8mph = 20 hrs
Domain of function = 0 ≤ x ≤ 20

The simplified expression of 4 +9 "/" 3 "/" 2 x 3 + (3 + 1) x 4 is 17, following the order of operations or PEMDAS.
To simplify the given expression, follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).
The original expression is 4 +9 / 3 / 2 x 3 + (3 + 1) x 4. First, address operations inside parentheses: (3+1) equals 4. The expression becomes 4 +9 / 3 / 2 x 3 + 4 x 4.
Next, handle the multiplication and division from left to right: 9 / 3 equals 3, and 2 x 3 equals 6. Then, 4 x 4 equals 16. This turns our expression into 4 + 3 - 6 + 16.
Finally, perform addition and subtraction from left to right: 4 + 3 equals 7, 7 - 6 equals 1, and 1 + 16 equals 17. Therefore, the simplified expression is 17.
