There are 1000ml in 1L. There for there are 4x250ml in 1L. Multiply 5x4 gives you 20. Therefore he needs to fill 20 water bottles to fill the jug
1. First, we are going to find the area of the sheet of plywood. The sheet of plywood is a rectangle, so to find its area, we can use the formula for the area of a rectangle:

where

is the area

is the width

is the length
We can infer from our problem that the width of the plywood's sheet is 24 inch and the length is 48 inch, so

and

. Lets replace those values in our formula:



square inches
Next, we are going to find the surface area birdhouse. The birdhouse is a rectangular prism with 5 inches width, 5 inches length, and 8 inches height, so we can use the formula for the surface area of a prism:

where

is the surface area

is the width

is the length

is the height
We already know those values, so lets replace them:


square inches
Since 210 square inches is less than 1152 square inches, we can conclude that Kali has enough plywood to build the birdhouse.
2. We know that there are 144 in^2 in 1 ft^2; those are a lot of square inches! We also know that the surface area of Kali's birdhouse is 210 in^2. Since there are a lot more than 210 square inches in 32.5 square feet, we can conclude that
he has more than enough painting to paint his bird house.
Hey there!
If she missed 4 problems, and that took off 20%, that means 4 is 20% of the total items.
20% is the same as 1/5 of the total amount, since there are 5 20s in 100.
So, we can simply multiply 4 by 5 to get the total amount of problems.
4 x 5 = 20
This means there were 20 problems on the test.
Hope this helps!
Answer: -3 + 4i
Step-by-step explanation: -3 +4 = 2.
2 +2 = 4 and I is an absolute number so i=1.
4 + I (1) = 5
