Which is more, 9 pints or 16 cups?
Answer:
9 pints
Step-by-step explanation:
there are two cups in a pint, so we need to divide 16 by 2 to convert the cups to pints.
16 ÷ 2 = 8
9 is greater than 8, so 9 pints.

Step-by-step explanation:
Two spotters of tornado are on a road running east-west and are 35 miles apart. The west man spots a tornado at bearing N 43° E and the east man spots the same tornado on a bearing of N 59° W. How far is the tornado from each man and how far is the tornado from the road?
The distance between the tornado, and both spotters is an illustration of bearing and distance.
The distance between the tornado and the spotter at the west is 30.67 milesThe distance between the tornado and the spotter at the east is 24.40 milesThe distance between the tornado and the road is 20.91 milesSee attachment for the positioning of the tornado, and the two spotters.
First, we calculate the angle T.
[tex]\mathbf{\angle T + 43 + 59 = 180}[/tex] ---- Sum of angles in a triangle
[tex]\mathbf{\angle T +102 = 180}[/tex]
Subtract 102 from both sides
[tex]\mathbf{\angle T = 78}[/tex]
From the attached figure:
y represents the distance between the tornado and the spotter at the westz represents the distance between the tornado and the spotter at the east x represents the distance between the tornado and the roadTo calculate y, we make use of the following sine formula
[tex]\mathbf{\frac{y}{sin(59)} = \frac{35}{sin(78)}}[/tex]
Make y the subject
[tex]\mathbf{y = \frac{35}{sin(78)} \times sin(59)}[/tex]
[tex]\mathbf{y = 30.67}[/tex]
To calculate z, we make use of the following sine formula
[tex]\mathbf{\frac{z}{sin(43)} = \frac{35}{sin(78)}}[/tex]
Make z the subject
[tex]\mathbf{z = \frac{35}{sin(78)} \times sin(43)}[/tex]
[tex]\mathbf{z = 24.40}[/tex]
Next, we calculate x, using the following sine trigonometry ratio
[tex]\mathbf{sin(59) = \frac{x}{z}}[/tex]
Make x the subject
[tex]\mathbf{x = z \times sin(59)}[/tex]
Substitute [tex]\mathbf{z = 24.40}[/tex]
[tex]\mathbf{x = 24.40 \times sin(59)}[/tex]
[tex]\mathbf{x = 20.91}[/tex]
Hence, the required distances are 30.67 miles, 24.40 miles and 20.91 miles.

Answer:
4
Step-by-step explanation:
1. 8^(2/3) is the same thing as [tex]\sqrt[3]{8^2}[/tex]
[tex]\sqrt[3]{8^2}[/tex] [tex]\sqrt[3]{64}[/tex] [tex]\sqrt[3]{64} = \sqrt[3]{4*4*4}[/tex] 4Therefore, (8)^(2/3) equals 4.
(del^(2)z)/(delx^(2))-4(del^(2)z)/(delxdely)+4(del^(2)z)/(dely^(2))=e^(2x+y)
Using Dz and D'z to denote partial derivatives of z with respect to x and y respectively, the equation becomes (D^2 -1)z=0 or (D-1)(D+1)z=0. Put (D+1)z = u(x,y). Then we have (D-1)u =0. The general solution of this equation is u(x,y)=A(y).e^x, where A(y) is an arbitrary function of y, because we have integrated a partial derivative of u with respect to x, and we have to take an arbitrary function of y instead of an arbitrary constant.
Now the original equation becomes
(D+1)z=A(y)e^x and we integrate it with respect to x, giving ze^x = Int[e^x.A(y).e^x.dx] + B(y), (for another arbitrary function B(y)) = (1/2)e^(2x).A(y) +B(y) or
z(x,y) = B(y)e^(-x)+[A(y)e^x]/2 or
z = B(y)e^(-x) + C(y)e^x. Hence putting x=0,
e^y = B(y)+C(y) and Dz= -e^(-x)B(y) + e^x.C(y). Again putting x=0, we get 1 = -B(y) + C(y). Solving the two equations in B(y) and C(y), we have C(y) = (1+e^y)/2, and B(y) = (e^y -1)/2. Hence the required solution is
z = [(e^y -1).e^(-x)]/2 + [(e^y +1).e^x]/2 =
z = (e^y)cosh(x) + sinh(x).

Question: Find the equation of the line specified.
Perpendicular to 3x + y = -7 and passing through (1,8)
(i really need an explanation on how to do this)
Answer:
[tex]y=\frac{1}{3}x+7.6666[/tex]
Step-by-step explanation:
First we must convert [tex]3x+y=-7[/tex] into slope-intercept form!
To do this we simply just need to subtract -3x from the 3x on the left and move it to the right side. This would result in: [tex]y = -3x-7[/tex]
Now that we have our slope-intercept form for the equation remember that to find the equation that is perpendicular to the given equation, you need to use the opposite reciprocal of the slope. This would be [tex]\frac{1}{3}[/tex] as that is the reciprocal and opposite of [tex]-\frac{3}{1}[/tex]
Now in order to find the "b" variable of the equation that goes through the ordered pair (1, 8) we need to plug it in to the given equation!
That equation would be: [tex]y=\frac{1}{3}x-7[/tex]
Given that x = 1 and y = 8 we can plug those in like so:
[tex]8=\frac{1}{3}(1)+b[/tex]
(make sure to set the -7 to b as that's what we're solving for)
1 / 3 is 0.3333 (infinitely repeating)
Next we need to subtract 0.3333 from 8, which would be 7.6666 (infinitely repeating) Remember that the variable needs to be "alone"!
Now we have our "b" for the equation! Hence the equation would be:
[tex]y=\frac{1}{3}x+7.6666[/tex]
(you can also use [tex]\frac{23}{3}[/tex] for the b as that is the "exact form" of 1 / 3 but they both work)

The value of the variable 'x' by the corresponding angles property will be 10.
What is an angle?The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360°.
Corresponding angle - If two lines are parallel then the third line. The corresponding angles are equal angles.
From the diagram, by the corresponding angles property, the equation is given as,
4x = 3x + 10
Simplify the equation, then we have
4x = 3x +10
x = 10
The value of the variable 'x' by the corresponding angles property will be 10.

Vertical angles = 81 degrees
Angle (4y-1) = 99 degrees
Linear pair = 81 + 99 = 180 degrees
Step-by-step explanation:
2x + 5 = 3x - 33 (vertical angles)
33+5 = 3x - 2x
38 = x
3(38) - 33 = 81 degrees
4y - 1 + 81 = 180 (linear pair angles)
4y = 180 - 80
y = 100/4
y = 25

A board is 22.5 Inches long. How long is the board in centimeters? Use the following conversion: 1 Inch is 2.54 centimeters.
Answer:
57.15
Step-by-step explanation:
22.5*2.54 is 57.15
The board is 57.15 centimeters long.
To convert the length of the board from inches to centimeters, we need to use the conversion factor of 1 inch equals 2.54 centimeters.
Given that the board is 22.5 inches long, we can multiply this value by the conversion factor to find the equivalent length in centimeters.
Length in centimeters = Length in inches × Conversion factor
Length in centimeters = 22.5 inches × 2.54 centimeters/inch
Calculating this expression:
Length in centimeters = 57.15 centimeters
Therefore, the board is 57.15 centimeters long.
