Answer:
$143.2
Step-by-step explanation:
20% of 179 is 35.8
so 179-35.8 = 143.2
Volume of a Cylinder:
V = pi * r^2 * h
Plug in what we know:
V = 3.14 * 0.5^2 * 5
V = 3.925
Now we divide 3.925 / 0.48 to find out how many batches of mortar we can make with one cylinder of sand.
3.925 / 0.48 = 8
So he can make 8 batches of mortar.
In general, if we have then Thus, the first answer choice is correct.
Answer:
2 1/3 hours or 2 hrs, 20 min
Step-by-step explanation:
1 5/6 + 1/2
make mixed number into improper fraction and change 1/2 to 3/6
11/6 + 3/6 = 25/6
14/6 equals 2 2/6 which simplifies to be 2 1/3 or 2 hrs, 20 min
Answer:
y = -5x - 21
Step-by-step explanation:
Given in the question,
equation of a parallel line
y = -5x + 6
point through which it passes
(-4,-1)
Step1
Find the gradient of the equation given, as it is parallel so it will have same gradient
equation of straight line
y = mx + c
where m is gradient
c is y intercept
y = -5x + 6
m =-5
Step2
Find y-intercept
-1 = -5(-4) + c
-1 = 20 + c
c = -20 - 1
c = -21
Step3
form the equation
y = -5x - 21
