The formula for the sum of the a finite geometric series is this:
Sn = a((1-r^n) / (1-r))
The given values are:
n = 30
a = 0.5 mi
r = 1.10 (10% more each day)
S30 = 0.5 ((1-1.10^30) / (1-1.10))
S30 = 82.25 mi
After 30 days, he will have traveled 82.25 miles.
30 mins = 42 cupcakes
1 min = 42 ÷ 30
1 min = 1.4 cupcakes.

Answer:
Milk: 2 cups
Flour: 5 cups
Sugar: 4 cups
Step-by-step explanation:
(First divide all ingredients by 2)
Milk: 3 -> 1.5
Flour: 5 -> 2.5
Sugar: 6 -> 3
(Next, multiply all by 4)
Milk: 1.5 -> 6
Flour: 2.5 -> 10
Sugar: 3 -> 12
(Divide by 3)
Milk: 6 -> 2
Flour: 10 -> 5
Sugar: 12 -> 4
Answer:
360 miles
Step-by-step explanation:
If you travel 90 miles in 1 ½ hours, it will take 360 miles if you drove 6 hours.
All you have to do is, multiply 1 ½ until you get to 6.
The easiest way is:
1 ½ = 90 miles
1 ½ (90 miles) x 2 = 3 or 180 miles
3 (180 miles) x 2 = 6 or 360
Therefore, 6 hours = 360 miles.
I'm in middle school (8th grade) and this is relatively easy, for me, so...
if each batch of muffins can make 6 muffins, and she makes 2.5 batches of blueberry muffins which will make 15 muffins, she will need to make 7.5 batches of banana muffins to equal 45 muffins and 45 + 15 = 60 muffins.
Here is the math part of it......
1 batch = 6 muffins
She makes 2.5 batches, 2.5 * 6 = 15 muffins
x*6 = 45
divide 6 by both sides to get this
x = 7.5
She needs to make 7.5 batches in order to make the rest of the 60 muffins
