<span>Let us first make the units same (like terms). Convert 2 feet into inches since the other term is already in inches. It is 24 inches. Now the ratio is 18 inches to 24 inches. To convert a ratio into a fraction, simply use the first number as the numerator and the second number as the denominator. So the fraction is 18/24. There are common factors in 18 and 24 which can divide both these numbers. 2 is a common factor and when both the numerator and denominator are divided by 2, the fraction becomes 9/12. The next common factor is 3. Divide both the numbers by 3. Now the fraction becomes 3/4. Since there are no more common factors, the fraction is in its lowest form.</span>

A circular plot with a 160 foot diameter is watered by a spray irrigation system. To the nearest square foot, what is the area t
Anuta_ua [19.1K]

A circular plot is watered by a sprinkler that rotates through it. The sprinkler only rotates through a semi-circle, or half of the whole circle.

Area of a circle: A = pi x r^2

r = 160 / 2 = 80

A = pi x 80^2

A = 6400pi / 2 = 3200pi

3200pi = 10053.0965

The area water is approximately 10,053 ft^2.

Hope this helps!! :)

<u><em>Hi there! :) :D</em></u>

<u><em>Answer:</em></u>

<u><em>A. -9</em></u>

<u><em>*The answer must have a negative sign.*</em></u>

Step-by-step explanation:

Lesson: Dividing integers

First, you divide by the numbers from left to right.

72/8=9

It change positive to negative sign.

72/9=8

Then, you can also multiply by the numbers from left to right.

9*8=72

8*9=72

<u><em>Final answer is -9</em></u>

Hope this helps!

Have a nice day! :)

:D

BE is parallel to CD.
Viktor [21]

Answer:

CD = 8 cm

Step-by-step explanation:

Given

See attachment

AE=6 cm,\ ED=4 cm,\ AB=4.5 cm,\ BE=4.8 cm.

Required

Find CD

To calculate CD, we first calculate BC using the following equivalent ratio

AB : BC = AE:ED

Substitute values for AB, AE and ED

4.5 : BC = 6 : 4

Express as fraction

\frac{4.5 }{ BC} = \frac{6 }{ 4}

Cross Multiply

BC * 6 = 4.5 * 4

BC * 6 = 18

Divide through by 6

BC = 3

To calculate CD,

We make use of the following equivalent ratio

AB : BE = AC : CD

Where

AC = AB + BC

AC = 4.5 + 3

AC = 7.5

So, we have:

AB : BE = AC : CD

4.5 : 4.8 = 7.5 : CD

Express as fraction

\frac{4.5 }{ 4.8 }= \frac{7.5 }{ CD}

Cross Multiply

4.5 * CD = 7.5 * 4.8

Divide through by 4.5

CD = \frac{7.5 * 4.8}{4.5}

CD = \frac{36}{4.5}

CD = 8
