Answer:
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
10*y-(80)=0
Pull out like factors :
10y - 80 = 10 • (y - 8)
Solve : 10 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solve : y-8 = 0
Add 8 to both sides of the equation :
y = 8
I haven’t taken this since for a while so my memory’s a bit foggy but I’m pretty sure it’s B since it intersects at (0,0) so there wont be any other solution. I hope that helps (:
Answer:
24
Step-by-step explanation:
Factorial is applicable only for natural numbers and 0.
0! =1 trivially.
FOr other numbers, factorial is defined as 1x2x...n
For example 1! = 1
2! = 1x2 = 2
and so on.
i.e. n! = product of all natural numbers from 1 to n
= 1x2x....n
Using the above
we have n =4
Natural numbers from 1 to 4 are 1,2,3,4
Find the product of these 4 natural numbers to get 4!
4! = 1x2x3x4 = 24
The area of an equilateral triangle of side length "s" is
.. A = (√3)/4*s^2
Your triangle will have an area of
.. A = (√3)/4*6^2 = 9√3 . . . . . square units
Ew, mental math... so basically, we would estimate the washing dishes to 20 minutes, and cleaning 40 min,
together 20+40 min
is 60 minutes, aprox 1 hour
Shelly spent almost 1 hour cleaning
