1. Which of the following shows the correct use of the Distributive Property when solving 1/3( 33

vagabundo [1.1K]

Answer:

The option $(\frac{1}{3}\times 33)-\frac{1}{3}y=\frac{1}{3}135.2$ is correct

Step-by-step explanation:

Given equation is $\frac{1}{3}(33-y)=135.2$

The option shows correct usage of distributive property is

$(\frac{1}{3}\times 33)-\frac{1}{3}y=\frac{1}{3}135.2$

( by distributive property $a(x+y)=ax+ay$ here $a=\frac{1}{3}$ , x=33 and y=-y )

Therefore the option $(\frac{1}{3}\times 33)-\frac{1}{3}y=\frac{1}{3}135.2$ is correct.

Find the radius and diameter of a circular puddle whose

o-na [289]

Answer:

$r = 35cm$

Step-by-step explanation:

Given

$C = 220cm$

$\pi = \frac{22}{7}$

Required

Determine the radius

Circumference (C) is calculated as:

$C = 2\pi r$

Where r represents radius

Substitute values for C and $\pi$

$220cm = 2 * \frac{22}{7} * r$

$220cm = \frac{44}{7} * r$

Multiply through by 7/44

$\frac{7}{44} * 220cm = \frac{7}{44} * \frac{44}{7} * r$

$r = \frac{7}{44} * 220cm =$

$r = \frac{7 * 220cm }{44} =$

$r = \frac{1540\ cm}{44}$

$r = 35cm$

<em>Hence, the radius is 35cm</em>

Noah made his aunt a garden. The width is 6 5/7ft and the length is 7 3/5ft. What is the area of the garden?

mixer [17]

Answer:

51 1/35 ft²

Step-by-step explanation:

Area of a rectangle = length x width

6 5/7 x 73/5

to multiply both figures, convert the mixed fractions 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

47/7 x 38/5 = 1786 / 35

convert the improper fraction to a mixed fraction = 51 1/35 ft²
