50 POINTS GIVING BRAINLIEST
Draft a small paragraph Explaining the concept of ground speed and horizontal distance traveled or distance traveled over the earth. Consider in your description what information is needed to calculate distance traveled.
Answers
Answer:
miles to travel directly south = 54 miles (to the nearest mile)
extra miles = 68 miles (nearest mile)
Step-by-step explanation:
We need to find the height of the right triangle in the diagram.
To do this, use the sine trig ratio.
[tex]\sin(x)=\sf\dfrac{O}{H}[/tex]
where:
[tex]x[/tex] is the angleO is the side opposite the angleH is the hypotenuseGiven:
[tex]x[/tex] = 27°
O = height (h)
H = 120 miles
Substituting the given values into the formula:
[tex]\implies \sin(27^{\circ})=\sf\dfrac{h}{120}[/tex]
[tex]\implies \sf h=120 \sin(27^{\circ})[/tex]
[tex]\implies \sf h=54.47885997...[/tex]
Therefore, the shipmate will have to travel 54 miles (to the nearest mile) directly south.
To find the number of extra miles have been traveled, we first need to find the base length of the right triangle.
To do this, use the cos trig ratio.
[tex]\cos(x)=\sf\dfrac{A}{H}[/tex]
where:
[tex]x[/tex] is the angleA is the side adjacent the angleH is the hypotenuseGiven:
[tex]x[/tex] = 27°A = base (b)H = 120 milesSubstituting the given values into the formula:
[tex]\implies \cos(27^{\circ})=\sf\dfrac{b}{120}[/tex]
[tex]\implies \sf b=120 \cos(27^{\circ})[/tex]
[tex]\sf \implies b=106.9207829...[/tex]
Therefore, the base of the right triangle is 106.9207829... miles
To find the extra miles, sum the hypotenuse and the height of the triangle, then subtract the base.
Extra miles = (120 + 54.47885997... ) - 106.9207829...
= 67.55807707...
= 68 miles (nearest mile)

Answer:
A=4000
B=560
C=32
Step-by-step explanation:
500*8=4000
70*8=560
8*4=32
Answer:
A = 4000
B = 560
C = 32
574 x 8 = 4592
Step-by-step explanation:
To find the area of A, we must multiply 500 by 8 because those are the dimensions.
500 x 8 = 4000
Therefore, A = 4000
To find the area of B, we must multiply 70 by 8.
70 x 8 = 560
Therefore, B = 560
To find the area of C, we must multiply 4 by 8.
4 x 8 = 32
Therefore, C = 32
To find the total area, we can add the area of A, B, and C together.
4000 + 560 + 32 = 4592

Classify Each triangle by its angle and sides.
Answers
Answer:
8. Scalene 9. Isosceles
Step-by-step explanation:
8) Acute Scalene
9) Right Isosceles
Step-by-step explanation:Triangles can be classified in 3 ways based on their angles: acute, obtuse, and right. There are 3 ways to classify based on sides: scalene, isosceles, and equilateral.
Definitions
Acute - a triangle with 3 acute angles (angles under 90 degrees)
Obtuse - a triangle with 1 obtuse angle (angle greater than 90 degrees)
Right - a triangle with 1 right angle (90-degree angle)
Scalene - a triangle with sides of all different lengths
Isosceles - a triangle with 2 equal sides and angles
Equilateral - a triangle with 3 equal sides
Question 8
From the 2 angles we are given, we can tell that all of the angles are different. This must mean that the sides are also different. Since the sides are different, this must be a scalene triangle. Additionally, the missing angle is 100 degrees; thus, it must be an obtuse triangle.
Question 9
The marks on the 2 sides mean that these lines are equal. Therefore, it must be an isosceles triangle. One of the angles is marked with a box. This means that the angle is 90 degrees. So, it is a right triangle.

Select all of the equations that are equivalent to `3x+45=180`.
A. 3 (x + 45) = 180
B. 3 (x + 15) = 180
C. 3 (x + 15) = 60
D. x + 15 = 60
E. 3x = 135
Answers
Answer:
Option B and Option D
Step-by-step explanation:
B = 3*x = 3x, 3*15 = 45.
D=3* x + 15.
3x = 135 and x + 15 = 60 are the equations that are equivalent to 3x+45=180
What is Equation?Two or more expressions with an Equal sign is called as Equation.
We have to solve the equation 3x+45=180
Now isolate x on one side of the equation.
We can do this by subtracting 45 from both sides, giving us 3x=135, and then dividing both sides by 3 to get x=45.
Therefore, the equivalent equations are:
3x = 135
x + 15 = 60
Hence, 3x = 135 and x + 15 = 60 are the equations that are equivalent to 3x+45=180

The origin is located in Quadrant |.
True
The ordered pair (2,-5.2) is located in Quadrants IV.
To Plot points in Quadrant |||, move left and down from the origin.
Step-by-step explanation:
The ordered pair (2,-5.2) is located in Quadrants IV. True
True, because Quadrants IV contains order pairs of the form of (+,-)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Quadrant || contains ordered pairs of the form (Positive number, Negative number False
False, because Quadrant || contains order pairs of the form (-,+)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The point (-6,0) is located on the y-axis False
False, the abscissa or x-coordinate is −6 and the ordinate or y-coordinate is 0. We know, any point on the x-axis has the form (a,0) and any point on the y-axis has the form (0,a), where a is any number.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The origin is located in Quadrant |. False
Origin always in the middle.
We know, the origin is the point of intersection of the x-axis and the y-axis. That is, when x=0 and y=0, we get the origin.

To Plot points in Quadrant |||, move left and down from the origin. True
Starting at the origin then move left would give us to Quadrant || and then down would give us Quadrant |||.

total score of B = 25*8 = 200
total score of C = 20y
(6x+200)/(x+25)=7.25
6x+200 = 7.25x+181.25
18.75 = 1.25x
x = 15
and
(6x+200+20y)/(x+25+20) = (6x+200+20y)/(x+45) = 6.5
plug in x
(290+20y)/60 = 6.5
