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.

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
Solve the inequality (one-step):
10 < b - 8
Answer:
B>18
Step-by-step explanation:
I like to rewrite it like this:
b-8>10
Now solve:
b>18
Answer: b >18
Step-by-step explanation: add 8 to both sides .( 8+10 < b - 8+8) now you get 18 < b .But variable must go first so you put b and then flip the inequality sign to > and put 18.So now you have b >18 as your inequality.
Hope it helps :)

Answer:
You multiply 5 by 1/5 to get 1. So with 2x, you multiply by 1/(2x) to get 1. That's about all you know, since we only know that x is positive.

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

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.

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

What degree measure is equivalent to 5π?
900°
450°
36°
90°
Answer:
900
Step-by-step explanation:
The equivalent degree measure of 5π ard is 900°.
What are the measure of reference angles according to quadrats?We have I, II, III, IV quadrants.
In quadrant I the referece angle Ф is Ф.
In quadrant II the referece angle Ф is (π - Ф).
In quadrant III the referece angle Ф is (π + Ф).
In quadrant IV the referece angle Ф is (2π - Ф).
We know π is equal to 180°.
The conversion of radian to degrees is we multiply the radian value by 180°/π.
Given, The radian measure is 5π.
Therefore, the equivalent degree measure is,
= (5π)×(180/π).
= (5×180)°.
= 900°.
