Answer:
Determine what quadrant the angle is in
An angle is said to be in standard position if its vertex is at the origin and its initial side is along the positive x-axis. An angle is said to be in the first quadrant, if in the standard position, its terminal side falls in the first quadrant.

simplify 2x4 a_3 =16a÷8 1_a
Answer:
(a+2) (a-18)
Step-by-step explanation:
Factoring a2-16a-36
The first term is, a2 its coefficient is 1 .
The middle term is, -16a its coefficient is -16 .
The last term, "the constant", is -36
Step-1 : Multiply the coefficient of the first term by the constant 1 • -36 = -36
Step-2 : Find two factors of -36 whose sum equals the coefficient of the middle term, which is -16 .
-36 + 1 = -35
-18 + 2 = -16 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -18 and 2
a2 - 18a + 2a - 36
Step-4 : Add up the first 2 terms, pulling out like factors :
a • (a-18)
Add up the last 2 terms, pulling out common factors :
2 • (a-18)
Step-5 : Add up the four terms of step 4 :
(a+2) • (a-18)
Which is the desired factorization

Answer:
c =2
Step-by-step explanation:
2(6c+2)+3c=2 (19 -c)
1. Distribute
2(6c +2 ) + 3c = 2 ( 19 - C )
12c + 4 +3c = 2 (19 - C )
2. Combine like terms
12c + 4 + 3c = 2 ( 19 - c )
15c + 4 = 2 (19 - c )
3. Rearrange terms
15c + 4 = 2( 19 - C )
15c + 4 = 2 ( -c + 19 )
4. Distribute
15c + 4 = 2 ( -c + 19 )
15c + 4 = -2c + 38
5. Subtract 4 from both sides of the equation
15c + 4 = -2c + 38
15c + 4 -4 = -2c + 38 -4
6. Simplify
Subtract the numbers
Subtract the numbers
15c = -2c +34
7. Add 2c to both sides of the equation
15c = -2 +32
15c +2c = -2c + 34 + 2c
8. Simplify
Combine like terms
Combine like terms
17c = 34
9.Divide both sides of the equation by the same term
17c = 34
17c/17 = 34/17
10. Simplify
Cancel terms that are in both the numerator and denominator
Divide the numbers
c = 2
3. Kathy earns a 6% commission on every house she sells. How much
commission would Kathy make on the sale of a $650,000 house
A. $3.900
B. $39.000
C. $390,000
D. $3.900.000
Please please help
Answer:
The correct answer is Option B: $39000
Step-by-step explanation:
Given that
Price of House = P = $650000
Rate of commission = r= 6%
In order to calculate the commission amount of Kathy, we only have to calculate 6% of $650000 or by simply multiplying the price by 0.06
So,
[tex]Commission = 6\%\ of\ 650000\\=0.06*650000\\=39000[/tex]
The commission is: $39000
Hence,
The correct answer is Option B: $39000

The surface of an office desk has an area of 18 square feet. Its perimeter is 18 feet. What are the dimensions of the desk?
Answer:
the dimensions are 3 and 6 feet
Step-by-step explanation:
xy=18
x+y=9
x=9-y
y(9-y)=18
-y^2+9y -18=0
y^2-9y+18=0
(y-6)(y-3)=0
if y=6, x=3
if y=3, x=6
Find the value of each variable in the parallelogram.
Answer:
m = 8
k = 7
Step-by-step explanation:
Diagonals of a parallelogram bisect each other. This implies that:
m = 8, also,
k + 4 = 11
k = 11 - 4 (subtraction property of equality)
k = 7

A custodian plans to repaint some classroom bookcases. She has 6 1/4 gallons of paint. All of the bookcases are the same size and each requires 2/3 gallon of paint. How many bookcases will the custodian be able to repaint with that amount of paint?
Answer:
9 bookcases
Step-by-step explanation:
(6 1/4) divide by 2/3 convert the first one to a mixed fraction, 6*4 =24 +1 = 25/4
and then common denominator 2/3 = 8/12 and 25/4 = 75/12 and then 75 / 8 = 9.----- but you can only paint 9.

A map has a scale of 1 inch : 3 miles.
How far are two airports apart if they are 6 inches apart on the map?
1. A circular running track is 1/4 mile long. Elena runs on this track, completing each lap in 1/20 of an hour. What is Elena's running speed, in miles per hour?
Answer: Elena's running speed = 5 miles per hour.
Step-by-step explanation:
Length of track = [tex]\dfrac14 \text{ mile}[/tex]
Time taken to complete one lap = [tex]\dfrac{1}{20}[/tex] of an hour.
Elena's running speed = [tex]\dfrac{Distance}{Time}[/tex]
[tex]=\dfrac{\dfrac14}{\dfrac1{20}}\text{ miles per hour}\\\\=\dfrac{20}{4}\text{ miles per hour}\\\\=5\text{ miles per hour}[/tex]
Hence, Elena's running speed = 5 miles per hour.

Answer:
[tex]\frac{25}{10x-1}[/tex]
Step-by-step explanation:
The multiplicative inverse of "a" is " [tex]\frac{1}{a}[/tex] "
a × [tex]\frac{1}{a}[/tex] = 1
~~~~~~~~~~~
[tex]\frac{1}{5}[/tex] ( 2x - [tex]\frac{1}{5}[/tex] ) = [tex]\frac{2}{5}[/tex] x - [tex]\frac{1}{25}[/tex]
1 ÷ ( [tex]\frac{2}{5}[/tex] x - [tex]\frac{1}{25}[/tex] ) = 1 ÷ ( [tex]\frac{10x}{25}[/tex] - [tex]\frac{1}{25}[/tex] ) = 1 ÷ ( [tex]\frac{10x - 1}{25}[/tex] ) = [tex]\frac{25}{10x-1}[/tex]
The multiplicative inverse of the product is [tex]\frac{25}{10x-1}[/tex]

Determine the slope (m) and y-intercept (b) of the line:
y = 1/2 x + 1
Answer:
m=1/2, b=1
Step-by-step explanation:
y=1/2x+1
y=mx+b
y is the y coordinate
m is the slope
x is the x coordinate
b is the y-intercept
You would identify that 1/2 is substituted into the equation as m aka the slope and 1 substituted for the b value aka y-intercept
