The total weight of the brass returned is 4.04 lb
In this question, we have to find the total conversion of brass return with 450 so multiply the conversion rate by the live rounds return back then we will get our exact answer as follows
A unit received rounds of .9mm = 1000
They return the number of live round units = 450
They return the number of live round units with a brass conversion = .009
so,
The total weight of the brass returned = 450 × .009
The total weight of the brass returned with a brass conversion = 4.05 lb

Kadeem and Quinn both drive 25 miles. Kadeem drives at a constant speed of 50 miles an hour. Quinn drives at a constant speed of 75 miles per hour. Who takes longer to drive 25 miles? How much longer?
Answer:
Kareem takes longer to drive the 25 miles. Kadeen takes 10 minutes longer than Quinn.
Step-by-step explanation:
The formula for time is distance over speed (distance/speed)
Kadeem
distance/speed = 25/50 = 1/2 hour = 30 minutes
Quinn
distance/speed = 25/75 = 1/3 hour = 20 minutes

The given coordinate pair, (10, -7) is not on the x–axis or the y–axis, but it is in Quadrant IV
What is a coordinate pair?
A coordinate pair specifies a point on the coordinate plane.
The coordinates of points on the x–axis have a y–coordinate of 0
Therefore, the coordinates of a point that is on the x–axis can be expressed as (x, 0)
Points that are on the y–axis have a x–coordinate of 0, which gives the coordinates of the points located on the y–axis as (0, y)
The coordinates of the given point is (10, -7), therefore, the point is neither on the x or y–axis, but in one of the four quadrants.
The coordinate of points in the first quadrant can be represented generally as (x, y)
Points in the second quadrant have the general form of (-x, y)
The points in the third quadrant can be expressed generally in the form (-x, -y)
The coordinates of points on the fourth quadrant are of the form, (x, -y)
The given point is (10, -7), therefore it is in the fourth quadrant or Quadrant IV

The range of elevations is 166 meters.
What is range?
Find the biggest observed value of a variable (the maximum) and subtract the smallest observed value to determine the range (the minimum). The data points between the distribution's two extremes are not taken into account by the range; just these two values are.
So as mentioned above, given to us are the lowest and highest values
So as the lowest value is 7 meters and the highest value is 173 .
Thus range is equal to 173-7

Find the value of x.
(3x + 3) (5x + 1)
Please help me:)
Answer:
x=22
Step-by-step explanation:
Since a straight line is equal to 180 degrees,
(3x+3)+(5x+1) = 180
(3x+3)+(5x+1)-180=0
8x+4-180=0
8x-176=0
8x=176
x=176/8
x=22
Which also means that the first angle is (3(22)+3)=69 degrees
the second angle is (5(22)+1) = 111 degrees
111 + 69 = 180

Answer: y = f (n 1)

Point G is on line segment \overline{FH}

. Given FH=4x+8,FH=4x+8, FG=x,FG=x, and GH=5x,GH=5x, determine the numerical length of \overline{GH}.
GH
.
The numerical length of GH = 20 units
FH is a line segment.
G is a point on the line segment.
Then G divides the line segment FH into two line segments FG and GH.
We are given the lengths of FH, FG and GH in terms of x.
That is, FH=4x+8, FG=x and GH=5x
We need to find the numerical length of the line segment GH. We first need to find the x for this.
As G cuts the line segment FH into two parts, the length of the line segment FH is the sum of the lengths of the line segments FG and GH.
That is, FH = FG + GH
⇒ 4x+8 = x +5x
⇒ 4x+8 = 6x
⇒ 2x = 8
⇒ x = 4
So the numerical length of GH = 5x = 5 x 4 = 20 units

Find the distance from a point (4, 6) to the line y = 2x - 5.
Answer:
1.34 units.
Step-by-step explanation:
The line y = 2x - 5 has a slope of 2 so the line passing through the given point will be perpendicular to y= 2x - 5 and will have a slope of -1/2.
Let this line be y = -1/2x + c.
Its passes through (4, 6) so:
6 = -1/2*4 + c
6 = -2 + c
c = 6 + 2 = 8
So, equation of this line is y = -1/2x + 8.
Now we find the point where the 2 lines intersect:
y = 2x - 5
y = -1/2x + 8
2x - 5 = -1/2x + 8
2x + 1/2 x = 5 + 8
(5/2)x = 13
x = 26/5
= 5.2.
and y = 2(5.2) - 5
= 5.4.
So, the point of intersection is (5.2, 5.4)
and the distance between the point (4,6) and the line y = 2x - 5
= √((6 - 5.4)^2 + (4-5.2)^2)
= √(0.36 + 1.44)
= √1.8
= 1.34
There is a formula you can use directly to solve this.

m∠D = 55°, DE ≈ 4.40 units, DF ≈ 13.65 units
D.
m∠D = 55°, DE ≈ 8.40 units, DF ≈ 14.65 units
Answer:
D
Step-by-step explanation:
the sum of the 3 angles in Δ DEF = 180° , that is
∠ D + 90° + 35° = 180°
∠ D + 125° = 180° ( subtract 125° from both sides )
∠ D = 55°
------------------------
using the tangent and cosine ratios in the right triangle
tan35° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{DE}{EF}[/tex] = [tex]\frac{DE}{12}[/tex] ( multiply both sides by 12 )
12 × tan35° = DE , then
DE ≈ 8.40 ( to 2 dec. places )
--------------------------
cos35° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{EF}{DF}[/tex] = [tex]\frac{12}{DF}[/tex] ( multiply both sides by DF )
DF × cos35° = 12 ( divide both sides by cos35° )
DF = [tex]\frac{12}{cos35}[/tex] ≈ 14.65 ( to 2 dec. places )
