Answer:
V=129659.9491≈129659.95
Step-by-step explanation:
<span>log (M/N) = log M - log N
so log M - log N = 5
log (P/N) = log P - log N
so log P - log N = 7
If you subtract equation 2 from equation 1, you have log M - log P = -2
That means that log (M/P) = -2 ----> 10^-2 = M/P ---> P = 100M</span>
Remember to follow PEMDAS (Parenthesis, Exponents (&roots), Multiplication, Division, Addition, Subtraction)
20-3•6+10²+(6+1)•4
First, solve the parenthesis
6 + 1 = 7
20 - 3 x 6 + 10² + 7 x 4
Next, solve the exponent
10² = 10 x 10 = 100
20 - 3 x 6 + 100 + 7 x 4
Next, solve each multiplication. Remember to bring your sign.
-3 x 6 = -18
7 x 4 = 28
20 - 18 + 100 +28
Simplify
(20 - 18) + (100 + 28)
2 + 128
130
130 is your answer

You use $25 each week for food from the grocery store how many weeks if you have 145,775
At constant acceleration the equation is
v = u + at where u = initial speed, a = acceleration. t = time and v = final speed
So here we have 18 = 0 + 7t
t = 18/7 = 2.6 seconds ( to nearest tenth)
