Item 20 Two groups leave on different flights from the same airport. Group A flies 130 miles due west, then turns 24° toward north and flies 45 miles. Group B flies 130 miles due north, then turns 32° toward east and flies 45 miles. Which group is farther from the airport?
Answer:
Group A
Step-by-step explanation:
Since in total they moved the same amount of miles then the one with the least turnback (angle in this case) would be farther

1 The graph shows the relationship between the weights of 5 packages and the shipping charge for each package. Is the relationship represented by the graph a function? Explain. I
Answer:
Step-by-step explanation:
Yes, each input value is paired with only one output value.
The function represent the given graph is f(x)=0.67x+1.83.
What is the equation of a line?The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.
From the graph, the coordinate points are (1, 2.5) and (2.5, 3.5)
Here, slope m=(3.5-2.5)/(2.5-1)
= 1/1.5
= 0.67
Substitute m=0.67 and (x, y)=(1, 2.5) in y=mx+c, we get
2.5=0.67+c
c=1.83
Substitute m=0.67 and c=1.83 in y=mx+c, we get
y=0.67x+1.83
Therefore, the function represent the given graph is f(x)=0.67x+1.83.

What is list?A list is a structure consisting of an ordered set of numbers.
What is the range?"The range is the difference between the smallest and highest numbers in a list."
For given example,
The range for the given list is 7 and the smallest value is 4.
Let R be the range of the list.
⇒ R = 7
Let S be the smallest value in the list.
⇒ S = 4
Let the largest value in the list be L.

Answer
x = 21
HOS = 68
Explanation
The arrows beside x point to 12 and 6, which is a straight angle. Straight angles always add up to 180 degrees.
So that means 3x+5 plus 5x+7 must equal 180 degrees.
3x+5+5x+7 = 180
Combine like terms.
8x+12 = 180
Subtract 12 from both sides.
8x = 168
x = 21
But BE CAREFUL.
The problem is asking for the angle HOS.
To do this, just substitute what you got for x into the expression.
3(21)+5 = 68
The value of HOS is 68 degrees.

Answer:
y = 6
Step-by-step explanation:
you cross multiply so 3 x 16 = 46 and 8 x y = 8y
it should look like this now -> 8y = 48
divide both sides by 8 -> y = 6
Answer:
y=6
Step-by-step explanation:
rewrite equation 16/y=8/3
multiply the numerator of the first fraction by the denominator of the second fraction. set this equal to the product of the denominator of the first fraction and the numerator of the second fraction
16 * 3= y * 8
rewrite equation as y*8=16*3
multiply 16 by 3
y*8=48
divide each term in y88=48 by 8
y=48/8
divide 48 by 8
y=6

Help
Answer:
10
Step-by-step explanation:
I simply divided 140/14 and got 10! Hope this helps :)
The 140 percentage of the number 10 is 14
Given data ,
To find the number that is 140% of another number, we can set up the equation:
140% of x = 14
So , 140 percentage of the number x = 14
To solve for x, we need to convert 140% to its decimal form, which is 1.40:
1.40 * x = 14
Now we can solve for x by dividing both sides of the equation by 1.40:
x = 14 / 1.40
Dividing 14 by 1.40 gives us:
On simplifying , we get
x = 10
Therefore , the value of x = 10
Hence , 140 percentage of 10 is equal to 14
