Answer:
Bob's typing speed is 39 words per minute.
Bill's typing speed is 58 words per minute.
Step-by-step explanation:
<u>Given : </u>
Bill can type 19 words per minute faster than bob. their combined typing speed is 97 words per minute.
<u>To Find : </u>
Bobs typing speed
<u>Solution : </u>
Let the bobs typing speed is x
According to the given question :
Bobs typing speed is x
Bill's typing speed is 19+x
Their combined speed is 97 words per minute.
<u>Solving value x : </u>
x + 19+x = 97
2x + 19 = 97
2x = 97 - 19
2x = 78
x = 78/2
x = 39
Bobs typing speed = 39
Bill's typing speed 39 + 19 = 58
Hence, Bobs speed is 39 words per minute.
Answer:
APart 1:
A.53 =53
B.3^5/3^-6 =177147
C.(1/4)^3 • (1/4)^2 = 1 /1024
D.(-7)^5/(-7)^7 = 1/49
Step-by-step explanation:
I tried my best for part 2 but i'm pretty sure it's not right. I think 1/1024 and 1/49 has a value between 0 and 1
Answer: X = 24
Step-by-step explanation:
Move all terms to the left:
(3x + 10) - (2x - 9) - 43 = 0
Get rid of all the parenthesis:
3x + 10 - 2x - 9 - 43 = 0
Add all the numbers and all variable:
x-24 = 0
Move all terms containing x to the left and all other terms to the right:
x = 24
Answer:
3 * n^(1/6)
Step-by-step explanation:
The square root can be written as ^ 1/2
The cube root can be written as ^ 1/3
So the sixth root can be written as ^ 1/6
3 * n^(1/6)
Answer: 3log5(2) - 1 or ~0,29203
Step-by-step explanation:
2log5(4) - log5(10)
log5(4^2) - log5(10)
log5(4^2/10)
log5(16/10)
log5(8/5)
Log5(8) - log5(5)
log5(2^3) - 1
3log5(2) - 1
