It was recently estimated that domestic vehicles outnumber foreign vehicles by about three to two. If there are 1925 vehicles in a county, how many of them are domestic?
Answers
If domestic vehicles outnumber foreign vehicles by about three to two and vehicles in a country are 1925 then Domestic vehicles would be {(1925)x(3/5)} = 1155
Assume that the growth of the membership of a country club was linear from 1996 to 2000 with a membership of 169 in 1996 and a rate growth of 674 per year
Answers
The equation for the number of members after [tex]x[/tex] years is [tex]P=674x+169[/tex].
The members after [tex]6[/tex] years are [tex]4213[/tex].
Let [tex]x[/tex] be the number of years after [tex]1996[/tex] and [tex]P[/tex] be the number of members.
The membership in [tex]1996[/tex] is [tex]169[/tex].
Rate growth of [tex]674[/tex] per year.
So, the equation for the number of members after [tex]x[/tex] years is [tex]P=674x+169[/tex].
For the members after [tex]6[/tex] years, put [tex]x=6[/tex] in the equation,
[tex]P=674 \times 6 + 169[/tex]
[tex]P=4044+169[/tex]
[tex]P=4213[/tex].

In the diagram below find the measure of each of the three angles and then state which two are complementary and which two are a supplementary pair. Answer question 1 and two.
Answers
1) ∠C and ∠G are supplementary while ∠A and ∠G are complementary.
2) Yes, ∠D is supplementary to ∠GAH
This is based on understanding complementary and supplementary angles.
By definition, complementary angles are two angles whose sum is equal to 90°. Meanwhile supplementary angles are those whose sum is equal to 180°.
1) From the angles drawn, we can see that ∠A and ∠G are less than 90° while ∠C is greater than 90° but less than 180°.
From inspection, ∠A looks same angle with ∠G. But, for them to be complementary they have to add up to 90°. Thus;
∠A + ∠G = 90°
Since ∠A = ∠G, then ∠A = ∠G = 90/2 = 45°
Now, ∠C appears to be the remaining part of ∠G to complete a straight line.
We know that sum of angles on a straight line is 180°
Thus;
∠C + ∠G = 180°
∠C + 45° = 180°
∠C = 180° - 45°
∠C = 135°
Thus, ∠C and ∠G are supplementary while ∠A and ∠G are complementary.
2) We see that ∠D = 63°
For ∠D to be supplementary to ∠GAH, it means that ∠GAH must be 180° - 63° = 117°
By inspection, it looks permissible.
Thus, ∠D is supplementary to ∠GAH

Therefore, the first number in an ordered pair is a value for x, and the second number is a value for y. These numbers are called the x- and y-coordinates.Jan 6, 2020
Answer:
x = 42
y = 48
Step-by-step explanation:
Because opposite angles are equal:
2x - 11 = 73
Add 11 to each side:
2x - 11 + 11 = 73 + 11
Simplify
2x = 84
Divide both sides by 2:
x = 42
And because angle y is opposite to the 48° angle, it is equal.
So y = 48

find the modulus of -2 - 6i
a. 6.3
b. -6.3
c. 40
d. -40
Answers
Using concepts of complex numbers, it is found that the modulus of -2 -6i is of 6.3, given by option A.
--------------------------------
A complex number has the format a + bi, in which a represents the real part and b represents the imaginary part.The modulus of the number, also called absolute value, is given by [tex]|a + bi| = \sqrt{a^2 + b^2}[/tex].In this question, the number is -2 -6i, thus [tex]a = -2, b = -6[/tex], and the modulus is:
[tex]|-2 -6i| = \sqrt{(-2)^2 + 6^2} = \sqrt{4 + 36} = \sqrt{40} = 6.3[/tex]
The modulus of -2 -6i is of 6.3, given by option A.

Statin sales reached 20 billion dollars in the year ________
Answers
Sales of statin on January 1, 2007 was 16.6 billion dollars.
Statin sales reached 20 billion dollars in the year 2009
Explanation :
The equation: S= 1.3x + 4.9 estimates the amount of sales, S, of statin (in billions of dollars) x years after January 1, 1998.
In 1998, the value of x=0
We need to find the sales in 2007.
2007 - 1998= 9 years
x=9 for the year 2007.
Substitute x=9 in the given equation S to find out sales
[tex]S= 1.3x + 4.9\\S= 1.3(9) + 4.9\\S=16.6[/tex]
Sales of statin on January 1, 2007 was 16.6 billion dollars.
Now we find out the year when sales reached 20 billion dollars
S is the amount of sales in billion dollars .
Substitute 20 for S and solve for x
[tex]S= 1.3x + 4.9\\20=1.3x+4.9\\20-4.9=1.3x\\\\15.1=1.3x\\Divide \; by \; 1.3\\x=11.61538[/tex]
So , 11 years.
To find out the year , we add 11 with 1998
1998+11=2009
Statin sales reached 20 billion dollars in the year 2009
