This is a geometric sequence problem.
You have a sequence of;
2/3, 2, 6, 18, 54
Their common ratio is t1/t0 = 2/(2/3) = 3
Formula for G.P n terms is denoted by
ar^(n-1) = nth term
Where;
a - first term
r - common ratio
n - nth term in the sequence
So the exponential formula is basically that.
Example
To find the 3rd term which is 6
ar^(n-1) = (2/3)(3)^(3-1)
-> (2/3)(3)²
-> (2/3)(9)
-> (2)(3)
-> 6
She burned 1,400 calories total.
Explanation is 1.25miles times 8 days which gives you 10 miles, then you just do 140 times 10 for 1,400 total
Answer:
x = 9
Step-by-step explanation:
"The sum of 42 and a number x is 51" in "mathy" words:
42 + x = 51
Then, subtract both sides by 42:
42 + x - 42 = 51 - 42
So
x = 9
Construct an equation in which s is the number of tons of sugar to be transported 4500 + 150.25s = 3696 + 200.5s Solve for s 4500 - 3696 = 200.5s - 150.25s 804 = 50.25s s = 804/50.25 = 16 tons of sugar The cost is found by plugging this value into either side of the original equation; it is $6904.
The slope is:
Hence, each topping of the pizza cost $1.5
