Answer:
a) 1790 b) 1.79
Step-by-step explanation:
a) you just add to get the perimiter 2(900) + 2(400) to get 1790
b) 1000 meters makes a kilometer so we divide by 1000 and get 1.79 for the kilometers
Answer:
Cross Multiply.
Step-by-step explanation:
Multiply the denominator (3) of one side and the numerator (n).
Then, multiply the numerator (2) of on side and the denominator (4) of the other.
3n = 8
You divide both sides by 3 to have n be by itself, equaling ~2.6 or 8/3.
Answer:
$2875
Step-by-step explanation:
If the member ship costs 25 a month multiply it by 100 to find the amount of money made last month so 100*25=2500 to find the new amount take 100 add 40 and subtract 15 to find the number of people subscribed which is 115 multiply by 25 to get the total profit of 2875.
Here you have an equation with two unknown constants, a and b, plus 2 sets of points through which the graph goes.
Second point: 96 = a(b)^2
First point: 6 = a(b)^0 Then a = 6.
With a = 6, we can now write: 96 = 6b^2. Then b^2 = 16, and b=4.
Then y =6(4)^x (answer)
