-1 - (-4) = 3

17.
-1-1/3 - (-4) = 2-2/3

18.
2 - (-1) = 3

19.
3-1/2 - (-1) = 4-1/2


20.
3-1/2 - 2 .= 1-1/2

21.
3-1/2 - (-1-1/3) = 4-5/6

Step by step: I took one point and subtracted the second point to get the length of each segment. You could also look at the ruler and count from one point to the other.

Remember when you subtract a negative, the two negatives become a positive

Keith_Richards [23]

Answer:

  • length: 30 ft
  • width: 10 ft

Step-by-step explanation:

The description of the garden fits that of 3 squares arranged side-by-side. The area of each of those would be 100 ft², so their side length would be ...

  s = √A= √(100 ft²) = 10 ft

This dimension is the width of the garden, whose length is 3 times this amount.

The length and width of the garden are 30 ft and 10 ft, respectively.

A 45 foot ladder is leaning against a building. If the bottom of the ladder is 27 feet from the base of the building, how tall i
taurus [48]

Answer:

The height of building to the nearest foot is h = 36 foot

Step-by-step explanation:

We have given,

Length of ladder leaning against a building, l = 45 foot

Bottom length between ladder and the building , b = 27

Now, we need to find the height of building to the nearest foot.

Let the height of building be h.

Using Pythagoras theorem,

l^{2} = b^{2} +h^{2}

Here, l = 45 , b = 27 and h =?

So,

45^{2} = 27^{2} +h^{2}

h² = 45² - 27²

h = √(45² - 27²)

h = 36

The height of building to the nearest foot is h = 36 foot
