There are sparrows and cardinals that feed at mrs. sims bird feeder. the ratio of sparrows to cardinals is 3: 1. there are at least 7, but less than 11 sparrows that eat at mrs. sims bird feeder. put an s in the grid below to show the number of sparrows and a c to show the number of cardinals. there may be extra squares. (see attachment)

Please find the grid of Sparrows and Cardinals below.

Step-by-step explanation:

Ratio 3:1 of Sparrows to Cardinals

There are at least 7, but less than 11 sparrows that eat at Mrs. Sims bird feeder

Let's build the grid for sparrows and cardinals, this way:

Sparrows = 7 - 8 - 9 - 10 - 11

Cardinals = 2 - 3 - 3 - 3 - 4

For calculating the number of cardinals we use the ratio 3:1 and round the number of cardinals to the next whole number.

Number of sparrows 7 to 11

Number of cardinals 2 to 4

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50

rae me : d

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
