Answer:
It will cost $190.75 to paint the whole fence.
Step-by-step explanation:
109 * 7 = 763 because Length x Width = Area
0.25 * 763 = 190.75
F(-1)=2 and f(0)=3 are the answers that are not true
Answer:
65 in and 39 in respectively
Step-by-step explanation:
Let r be the common ratio; when we multiply both L and R by this common ratio, we'll get the actual length and actual width of the rectangle, Recalling that the formula for the perimeter of a rectangle is P = 2L + 2R, we get:
2(5r) + 2(3r) = 16r = 208 in
Then r = 208/16 = 13
Thus, the actual length is 5(13 in) and the actual width is 3(13 in.),
or 65 in and 39 in respectively.
As a check, calculate 65 in / 39 in; this comes out to 5:3, as required.
Then
10 hours.
If you multiply 2 1/2 by 4, the product is 10.
Answer:
The system cannot be solved by a unique cost for each soldier, because has infinite solutions
Step-by-step explanation:
Let
x-------> the cost of a legionary per day
y-------> the cost of an archer per day
we know that
------> equation A
------> equation B
Multiply equation B by
both sides
------->
so
equation A and equation B is the same equation
therefore
This is a consistent dependent system
The system has infinite solutions
