Answer:
2500
Step-by-step explanation:
[8*(3+4-1)+2]^2
First calculate the number inside the round parenthesis as this operation as priority:
3+4-1=6
Then multiply this by 8 because now the multiplication has the highest priority:
8*6=48
Now you can add the 2 to the number you got:
48+2=50
Finally square the number obtained to get the answer:
50^2= 2500
Answer:

Step-by-step explanation:
Let
x = the amount of time William has been digging
y = the amount he has left to dig
The hole has to be in 2 ft deep. This means when William starts, the hole was 0 feet deep and has left 2 ft to dig. Hence, y-intercept is 
He is able to dig at a rate of
ft per minute. Thus, the slope is
(negative because the depth left to dig is decreasing).
The slope-intercept form of the equation is
so in your case this equation is

Answer:
18 Kg of 64 Kg represents 9/32 parts
Step-by-step explanation:
We first represent the 18lg of the 64kg as a fraction that can still be reduced:

We see that the fraction can be reduced to its half, because both the numerator and the denominator can be simplified by 2.

By so:
<h3>18 Kg of 64 Kg represents 9/32 parts</h3>
Since it's a square we just need to 27*27
Which is 729
