I = prt
$460 x 0.025 x 4 = $46
Answer:
840
Step-by-step explanation:
The 3 by 3 grid below shows nine 1 cm x 1 cm squares and uses 24cm of wire
24 cm of wire
is 3 (3 + 1) + 3(3 + 1)
= 3 x 4 + 3 x 4
= 12 + 12
= 24 cm
length of wire is required for a similar 20 by 20 grid
= 20(20 + 1) + 20(20 + 1)
= 20 x 21 + 20 x 21
= 420 + 420
= 840 cm
Answer:
17/60 yards of scarf
Step-by-step explanation:
If 5 friends each had one part of a scarf that's 1 and 5/12 yards long what fraction of the scarf could each friend knit
To solve the above question:
5 friends = 1 5/12 yards
1 friend = x yards
Cross Multiply
5 × x = 1 × 1 5/12 yards
x = 17/12 yards ÷ 5
x = 17/12 yards × 1/5
x = 17/60 yards of scarf
If the equation is x/(x^2-4) then I will solve it here
it's rational
therefor we can't have any impossibles like dividing by zero and square root of -1 an d stuff
f(x)=x/(x^2-4)
we know that the denomenator cannot be equal to zero so the numbers you cannot user are the numbers that will make the bottom number zero
so x^2-4=0
x^2=4
x=-2 or 2
so x cannot be -2 or 2, but it can be all other numbers so
domain=all numbers except -2 and 2
Answer:
x = -5
Step-by-step explanation:
-(5x-2) = 27
Distribute the minus sign
-5x +2 = 27
Subtract 2 from each side
-5x +2-2 = 27-2
-5x = 25
Divide by -5
-5x/-5 = 25/-5
x = -5
