Divide each price by the number of cubic yards it buys to find the cost per cubic yard.

A. $165/(3 yd³) = $55/yd³

B. $240/(4 yd³) = $60/yd³

C. $300/(6 yd³) = $50/yd³

D. $360/(8 yd³) = $45/yd³ . . . . . . . this is the best price per cubic yard.

Lets get started :)

We are told that Mrs. Thymes is buying mulch for her gardens.

Let us check the price for each option:

\boxed {Option \ A}
3 yd³ for $165
Divide 165 by 3, to find the price per cubic yard:
\frac{165}{3} = $55 per cubic yard

\boxed {Option \ B }
4 yd³ for $240
Do the same:
\frac{240}{4} = $60 per cubic yard

\boxed {Option \ C }
6 yd³ for $300
\frac{300}{6} = $50 per cubic yard

\boxed {Option \ D }
8 yd³ for $360
\frac{360}{8} = $45 per cubic yard

Therefore, we can see that 8 yd³ for $360 is the best price

\boxed {Your \ Answer \ will \ be \ Option \ D }

You drive 15 miles in one fourth of an hour. What is your average speed?
Mazyrski [523]
Hello ! I'm happy to help
the answer all revolves around this simple formula:
speed= distance/time
since you were driving for 1/4 of an hour that's 15 minutes
and we already know that you traveled 15 miles
so the speed would equal 15 miles every 15 minutes
if you want to find the total distance travelled is 15x15 =225

Find the measure of each angle of triangle abc, given ac=6, cb= 2 square roots of 3, and ab= 4 square roots of 3
Mazyrski [523]
Note that 
(4sqrt3)^2 = (2sqrt3)^2 + 6^2     [ 48  =   12 + 36]  so the triangle is  a right angled one with hypotenuse AB 

So angle C = 90 degrees

sin A =   2 sqrt3 / 4 sqrt3 = 1.2  giving A = 30 degrees
and B = 90 - 30 = 60 degrees


A = 30, B = 60 and C = 90 degrees

A bicycle wheel has a small pebble embedded in its tread. The bike is set upside down, and the rider accidentally bumps the whee
nikdorinn [45]

Answer:

a) The radius of the wheel is 1) more than 25.0 cm.

b) The radius of the wheel is approximately 40.925556... cm

Step-by-step explanation:

S = rθ is the formula to find the radius of the wheel using the arc and the angle discovered, S being the arc and θ the angle. The angle, however, must be in radians. θ = \frac{35\pi}{180} is used to convert it. So:

θ = \frac{35\pi}{180}

θ = \frac{7\pi}{36}

S = rθ

25 = r \frac{7\pi}{36}

900 = 7\pir

r = \frac{900}{7\pi }

r = 40.925556... cm
