Answer:
Step-by-step explanation:
200(1+r)⁵⁻³ = 200(1+r)² = 800
(1+r)² = 4
1+r = 2
r = 100%
800(1+r)⁷⁻⁵ = 800·2² = 3200
Answer:
1200 copies
Step-by-step explanation:
In order to find how many copies can be printed in 10 minutes, first we need to find how many copies the machine can print in one minute. Let that be x.
480= 4x
Divide both sides by 4
120=x
Now, we need to multiply that by how many minutes we need to find.
120* 10= 1200
Thus, the machine can print 1200 copies in 10 minutes.
Answer:
y=-1
Step-by-step explanation:
The slope intercept form of a line is
y = mx +b where m is the slope and b is the y intercept
We know the slope is zero
y = 0x+ b
Substituting the values for x=-1 and y=-1 from the point we are given
-1 =0 +b
b=-1
Putting this into the original equation
y = 0x+-1
y=-1
<span>No, 7 is a natural number divisible by 7 and not 14 for example. In fact every odd multiple of 7 (i.e. 7 times 1,3,5,7,...) is divisible by 7 and not 14.</span>
What is the area the sprinkler can water?
Area = π r²
r = 18 feet
r² = r * r = 324
A = 3.14 * 324
A = 1017.36
A = 1017 square feet
