For Jamie to reach 1 1/2 acres she'd need to mow 1/6 of her yard nine times over, and since it's constant the time it takes to mow 1/6 is multiplied nine times over.

1/6 x 9/1 = 9/6 = 1 1/2 9 x 8 = 72 60<72

The sum of two number is 25 if thrice the smaller number is subracted from twice the larger number,the subtraction is also 25 fi

Mnenie [13.5K]

Answer:

The numbers are 5 and 20 respectively.

Step-by-step explanation:

Let two numbers are x and y.

According to question-

x + y = 25...............................(i)

Given x is smaller number and y is larger number.

then,

2 y - 3 x = 25..........................(ii)

To solve equation (i) and (ii)-

Firstly multiply by 3 in equation (i) and then add in equation (ii)-

3 x + 3 y = 75

- 3 x + 2 y = 25

5 y = 100

y = 20

Put y = 100 in equation (i)-

We get,

x = 25 - 20

x = 5

Therefore x = 5 and y = 20 .

A rectangular prism with a volume of 4 cubic units is filled with cubes with side lengths of 1/3 units. How many 1/3 units does

motikmotik

Answer:

108 cubes

Step-by-step explanation:

step 1

Find the volume of the cube with side length of 1/3 units

The volume of the cube is equal to

$V=b^3$

where

b is the side length

we have

$b=\frac{1}{3}\ units$

substitute

$V=(\frac{1}{3})^3$

$V=\frac{1}{27}\ units^3$

step 2

To find how many cubes are needed to fill the prism, divide 4 cubic units (volume of the rectangular prism) by 1/27 cubic units (volume of one cube)

$4:\frac{1}{27}=4*27= 108\ cubes$
