Answer:
In 4 hours, Brad will travel 220 miles.
Step-by-step explanation:
Create the direct variation model-
y = kx
<em>y- represents the total miles</em>
<em>x- represents hours</em>
<em>660 = k12</em>
<em>660/12 = k</em>
<em>k = 55</em>
<em>Model:</em>
y = 55x
<em>Replace x with 4</em>:
y = 55(4)
y = 220
The answer is 220 miles.
126.5 years
N(t) = 384(1.13)^t
2,000,000,000 = 384(1.13)^t
(1.13)^t = 2,000,000,000/384
log [(1.13)^t) = log (2,000,000,000/384)
t × log 1.13 = log (2,000,000,000/384)
t = [log (2,000,000,000/384)]/(log 1.13)
t = 126.5
Answer:23 cm
Because it would equal the same amount because there are 10 mm in a cm
2596\83 =31.2
2(5x-3y-1)
perimeter of a rectangle formula:
2l+2w
l=length(2x-3y)5x
w=width(3x-1)
2(2x-3y)+2(3x-1)
4x-6y+6x-2
10x-6y-2
2) all of these numbers have a gcf of 2 so lets divide this equation by 2:
hope this helps!
