I need help with this question.

SSSSS [86.1K]

Answer:

$\displaystyle S_{27}=675$

Step-by-step explanation:

The sum of N consecutive natural numbers is given by:

$\displaystyle S_N=\frac{N}{2}(F+L)$

We need to find the sum of the natural numbers between 12 to 38.

To calculate the required sum we have F=12, L=38, but we don't have the value of N.

From 12 to 38 there are 38 - 12 + 1 = 27 natural consecutive numbers, thus N=27.

Substituting in the formula:

$\displaystyle S_{27}=\frac{27}{2}(12+38)$

$\displaystyle S_{27}=\frac{27}{2}(50)$

$\displaystyle S_{27}=27*25$

$\mathbf{\displaystyle S_{27}=675}$

-Question Worth 50 Points-

Naddika [18.5K]

<span>At the city park there were 15 blue jays, 6 cardinals, and 9 mockingbirds.

6 mockingbirds is 2/3 of 9
so 2/3 of 6 is 4 cardinals

5 blue jays is 1/3 of 15
so 1/3 of 6 cardinals is 2 cardinals

There are 20 cardinals, how many mockingbirds.
the ratio is 2/3, so 20/30 is your answer

hope this helps</span>
