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.
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)

Suppose the planned dimensions of a rectangular kitchen have a length-to-width ratio of 3 to 2. The length of the original kitchen is 6z feet. The original kitchen can be made larger by adding four feet to each original dimension. Write a polynomial expression that represents the floor area of the larger kitchen in square feet. Write your answer in standard form.
Answer:
150 sq. in.
Step-by-step explanation:
Because... Suppose the planned dimensions of a rectangular kitchen have a length-to-width ratio of 3 to 2. The length of the original kitchen is 6z feet. The original kitchen can be made larger by adding four feet to each original dimension. Write a polynomial expression that represents the floor area of the larger kitchen in square feet.
The polynomial expression that represents the floor area of the larger kitchen in square feet is 24z² + 40z + 16
What is Area of Rectangle?The area of Rectangle is length times of width.
The length-to-width ratio of the original rectangular kitchen is 3 to 2.
Let the width of the original kitchen "w".
Then the length of the original kitchen is length = 3/2×w
We are also told that the length of the original kitchen is 6z feet. We can use this information to solve for the width of the original kitchen:
6z = 3/2×w
w = 4z
So the width of the original kitchen is 4z feet.
To make the kitchen larger, we add four feet to each original dimension. The new length is:
length = 6z + 4 feet
width = 4z + 4 feet
Area = (6z + 4 feet) × (4z + 4 feet)
Multiplying out the terms, we get:
Area = 24z² + 40z + 16 square feet
Therefore, the polynomial expression that represents the floor area of the larger kitchen in square feet is 24z² + 40z + 16

Solve the linear system
x+y=5
x-2y=-1
Find the ratio of the solution's y-coordinate to its x-coordinate.
Answer:
2:3
Step-by-step explanation:
x + y = 5 -----> y = 5 - x
x - 2y = -1
x - 2(5 - x) = -1
x - 10 + 2x = -1
3x - 10 = -1
3x = 9
x = 3
(3) + y = 5
y = 2
Solution to this system: (3,2)
Ratio of y to x = 2:3

The measure of two exterior angles from the given figure are 60° and 90°.
What is sum of exterior angles of polygon?An exterior angle is an angle which is formed by one of the sides of any closed shape structure such as polygon and the extension of its adjacent side. The sum of the measures of the exterior angles of a polygon is equal to 360 degrees, irrespective of the number of sides in the polygons.
From the given figure, the exterior angles are 70°, 2x°, 65°, 75° and 3x°.
Here, 70°+2x°+65°+75°+3x°=360°
210°+5x°=360°
5x°=150°
x=30°
So, 2x=60° and 3x=90°
Therefore, the measure of two exterior angles are 60° and 90°.

Answer:
B and C
Step-by-step explanation:
Kitten:
2 times in the morning and 2 times in the evening = 4 times per day
That means Ariane feeds her kitten 4k grams of food per day.
Dog:
1 time in the morning and 1 time in the evening = 2 times per day
That means Ariane feeds her dog 2d grams of food per day.
Answer:
If you find the total, you have to add the kitten's food per day and the dog's food per day. That is 4k + 2d, which is the same as choice B.
We can break 4k into 2k + 2k. We can also break 2d into d + d. We can write that as 2k + 2k + d + d. That equals the same as choice C, making it a correct choice.

16 players can be brought to the tournament. The equation is written within my step-by-step explanation.
Step-by-step explanation:
Variable p = number of players
Set up an equation:

Isolate variable p:
60.75p = 972
Divide:
p = 16

A drawer contains 5 red socks, 9 white socks, and 6 blue socks. Without looking, you draw out a sock and then draw out a second sock without returning the first sock.
Find P(blue, then blue).
Your answer:
P = Number of favourable outcomes ÷ Sum of total outcomes
So, Probability of drawing a blue sock is
Number of blue socks ÷ Number of total socks
= 6 ÷ 20
= 3 ÷ 10
= 0.3
Now as we have drawn a sock already the total number of socks in the drawer are 19
So, the probability of drawing a blue sock now will be :
= 6 ÷ 19
= 0.31

The first three terms of a geometric sequence are as follows.
Use the form |x-b|<=c or |x-b|>=c to write an absolute value inequality that has the solution set -1<=x<=3.
An absolute value inequality that has a solution set -1<=x<=3 is |x-1| <= 2
What is the solution set for an inequality?The set of values of the variable involved in the inequality for which the considered inequality holds true is called the solution set for that inequality.
We've to find an absolute value inequality that has the solution set
-1 <= x <= 3
1+2 = 3
and 1 - 2 = 3
Therefore, we can rewrite the considered inequality as:
1-2 <= x <1+2
Subtracting 1 from all the sides:
-2 <= x-1 <= 2
This is written as:
|x-1| <= 2 (it is because [tex]|x| \leq a \leftrightarrow-a \leq x \leq a[/tex] )
Thus, an absolute value inequality that has a solution set -1<=x<=3 is |x-1| <= 2

Debra needs 322 programs for the school play on Thursday. How many boxes of programs will she need, given that each box contains 48 programs?
Answer:
7 boxes
Step-by-step explanation:
Debra needs to fit 322 programs into boxes and each box can contain 48. Therefore, we must divide 322 by 48.
322 ÷ 48 ≈ 6.71
We need at least 7 boxes to contain the 322 programs because if we only have 6, then the remaining programs won't be in a box. Therefore, we have to round up to get 7 boxes.
