Answer:

area of the daises part of the garden = 1/3 x 30 1/2

10 1/6 square feet

Step-by-step explanation:

area of the daises part of the garden = area of garden x 1/3

= 1/3 x 30 1/2

Convert the mixed fraction to an improper fraction

to convert to improper fraction, take the following steps :  

1. Multiply the whole number  by the denominator

2. Add the numerator to the answer gotten in the previous step

3. divide the number gotten in the previous step by the denominator  

= 1/3 x 61/2 = 61/6

convert to mixed fraction

10 1/6

A fish fank was 3/4 full, and then 1/3 of the water leaked out,
QveST [7]

Answer:

5) It was 5/12 of the way full

6) It holds 48 gallons.

Step-by-step explanation:

For #5, you can simply find the lowest common denominator, which was 12, so you would multiply 3/4 by 3/3 and 1/3 by 4/4, giving you 9/12 and 4/12. Next you would subtract 4 from 9 and get the answer 5/12.

For #6 you can set up the problem as a ratio, 5/12 and 20/x, and then cross multiply, getting the equation 5x = 240. Then divide by 5 and you get the answer 48.

Hope this helps!!

Write the point-slope form of the equation of the line that passes through the points (6, -9) and (7, 1). Include your work in y
Taya2010 [7]
<h3><u>y + 9 = 10(x - 6) is the point-slope form of the equation of the line that passes through the points (6, -9) and (7, 1)</u></h3>

<em><u>Solution:</u></em>

<em><u>Given points are:</u></em>

(6, -9) and (7, 1)

<em><u>Let us find the slope of line</u></em>

m = \frac{y_2-y_1}{x_2-x_1}

From given,

(x_1, y_1) = (6,-9)\\\\(x_2, y_2) = (7, 1)

Therefore,

m = \frac{1+9}{7-6}\\\\m = \frac{10}{1}\\\\m = 10

Thus slope of line is 10

<em><u>The point slope form of line is given as:</u></em>

y - y_1 = m(x-x_1)

Substitute m = 10 and (x_1, y_1) = (6, -9) in above

y + 9 = 10(x - 6)

Thus the equation of line in point slope form is found
