Answer:

2 cubic yards

Step-by-step explanation:

In this problem we are simply finding the volume of a 3D shape. We can calculate this by L × W × H.

9.5 × 12 × 1/3 = 48 ft³

(Note: 4 inches is 1/3 foot)

This means Rosilaine needs 48 cubic feet of wood chips. However, the wood chips are sold in yards, so we need to convert cubic feet to cubic yards.

48 ÷ 27 = 1.777 (repeating decimal)

This means Rosilaine should buy 2 cubic yards of wood chips.

When the area in square units of an expanding circle is increasing twice as fast as its radius in linear units
alexira [117]

Answer:

r=1/π

Step-by-step explanation:

Area of the circle is defined as:

Area = πr²

Derivating both sides

\frac{dA}{dr}=2πr

\frac{dA}{dt}  =  \frac{dA}{dr} x \frac{dr}{dt}  =  2πr\frac{dr}{dt}

If area of an expanding circle is increasing twice as fast as its radius in linear units. then we have : \frac{dA}{dt}  =2\frac{dr}{dt}

Therefore,

2πr \frac{dr}{dt}  =  2  \frac{dr}{dt}

r=1/π

The complement of an angle is 25°. What is the measure of the angle?
lisabon 2012 [21]
Complement of an alngle means what you need to add to it to make 90 degrees

comlement of angle x is y such that x+y=90

so if complement of angle x is 25, that means the angle x is found by
x+25=90
minus 25 both sides
x=65 degrees

the angle measures 65 degree
