Here is your answer:

$- I21I = -21$

The 'I' around the 21 means to change positive but since how the negative since is out of the 'I' it doesn't change into a positive it's still a negative just without the 'I'.

Therefore the answer is "-21."

Hope this helps!

Illusion [34]

Mr. Patel used 4.5 bags of seed

Solution:

Given that,

Over the summer, Mr. Patel refilled a bird feeder 24 times using 6 cups of seed each time

A bag of seeds holds 32 cups

1 bag of seed = 32 cups

Given that Patel refilled 24 times using 6 cups of seed each time

Then, the number of cups used for the 24 times is given as:

$6 \times 24 = 144$

Now we have to find the bags of seed needed for 144 cups

Let "x" be the number of bags of seed for 144 cups

From given,

1 bag of seed = 32 cups

"x" bags of seed = 144 cups

This forms a proportion and we can solve it by cross multiplying

$144 \times 1 = 32 \times x\\\\144 = 32x\\\\x = \frac{144}{32}\\\\x = 4.5$

Thus 4.5 bags of seed is used by Mr.patel

Please help find the perimeter

Usimov [2.4K]

Answer:

Perimeter of the given figure = 28 units

Step-by-step explanation:

Perimeter of the given figure = Length of AB + Length of BC + Length of CD + Length of DE + Length of EF + Length of FG + Length of GH + Length of AH

Length of AB = 4.5 units

Length of BC = 2 units

Length of CD = 2 units

Length of DE = 4 units

Length of EF = 5.5 units

Length of FG = 1.5 units

Length of HG = 1 units

Length of AH = 7.5 units

Perimeter of ABCDEFGH = 4.5 + 2 + 2 + 4 + 5.5 + 1.5 + 1 + 7.5

= 28 units
