The radius of a circle is 3 yards. What is the circle's area? r=3 yd )) Use 3.14 for a.

The hanger image below represents a balanced equation.

Ghella [55]

Answer:

The equation is : r + 2 = 7

Step-by-step explanation:

1+1+1+1+1+1+1 = r + 1 +1

7 = r + 2

R = 7-2

R = 5

Franco read 3/8 of a chapter of his history book in 1/5 of an hour. At this rate, how many chapters of his history book can he r

Irina18 [472]

He can read $1\frac{7}{8}$ chapters of his history book in 1 hour.

Explanation

Franco read 3/8 of a chapter of his history book in 1/5 of an hour.

Suppose, he can read $x$ chapters of his book in 1 hour at this rate.

So, the equation according to the ratio of 'the chapter to the time' will be....

$\frac{x}{1}= \frac{\frac{3}{8}}{\frac{1}{5}}\\ \\ \frac{x}{1}=\frac{3}{8}*\frac{5}{1}\\ \\ \frac{x}{1}=\frac{15}{8} \\ \\ x= \frac{15}{8}= 1\frac{7}{8}$

So, he can read $1\frac{7}{8}$ chapters of his history book in 1 hour.

John has a storage bin in the shape of a rectangular prism the storage bed is still in the and 1/2 ft long 2 ft wide and 2 ft ta

Phoenix [80]

We know, volume of rectangular prism is given by :

$V = lbh\\\\V=\dfrac{1}{2}\times 2\times 2\ ft^2\\\\V=2\ ft^2$

Volume of cubic box :

$v=a^3\\\\v=(\dfrac{1}{2})^3\ ft^3\\\\v=\dfrac{1}{8}\ ft^3$

Number of cubes can be filled :

$N=\dfrac{V}{v}\\\\N=\dfrac{2}{\dfrac{1}{8}}\\\\N=16$

Therefore, 16 cubes can be put in the bin.

Hence, this is the required solution.
