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?
Answers
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
Answers
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

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?
Answers
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.

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°.

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
Answers
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

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.
