Answer:
6 cupcakes
Step-by-step explanation:
"Every 11 days, my dog eats 3 cupcakes" can be written as a proportional relationship in fraction form: .
Now, let's set a proportion between the values given.
As you can see, the number of days is multiplied by 2 to get 22 days. Whatever we do to the numerator, we must do to the denominator. Then, 3 multiplied by 2 is 6.
Therefore, the answer is 6 cupcakes.
Have a lovely rest of your day/night, and good luck with your assignments! ♡
= 1455
generate a few terms of the sequence using = 3n + 2
= ( 3 × 1) + 2 = 5
= (3 × 2) + 2 = 8
= (3 × 3 ) + 2 = 11
= (3 × 4 ) + 2 = 14
= ( 3 × 5 ) + 2 = 17
the terms are 5, 8, 11, 14, 17
these are the terms of an arithmetic sequence
sum to n terms is calculated using =
[ 2a + (n-1)d]
where a is the first term and d the common difference
d = 8 - 5 = 11 - 8 = 14 - 11 = 3 and = 5
=
[( 2 × 5) + (29 × 3) ]
= 15( 10 + 87) = 15 × 97 = 1455
