Hello there!

4³ + 2(3 - 2)

= 64 + 2(1)

= 64 + 2

= 66

The correct answer is option C

The second part*

A variable cubed >>>>> x³

Quotient of some number and three >>> b ÷ 3

Product of an unknown value and three >>>>> 3a

Three less than a variable >>>y - 3

Three more than some number >>>> z + 3

If you have any misunderstanding, please let me know. As always, I am here to help!

Answer:

Online store will save the most money

Step-by-step explanation:

Amount used in Physical store

Batteries 2packs @$5.99 cost = $5.99*2=$11.98

Stereo 1 system @$100 cost = $100*1=$100

CDs 3 CDs @$7.95 cost = $ 23.85

Total cost= $11.98+$100+$23.85= $135.83

Applying the 10% off coupon = 90/100 * $135.83 =$ 122.25

Applying sale tax 5% = 105/100 * 122.25=$128.36

Amount to spend when using physical store= $128.36

Now calculate for the online store

Batteries 2packs @$4.99 cost= $4.99*2=$ 9.98

Stereo 1 system @$90 cost= $ 90 *1= $90

CDs 3 CDs @$8.95 cost = $8.95*3=$26.85

Total cost=$9.98+$90+$26.85=$126.83

Applying the 5% off coupon= 95/100*126.83=$120.49

Applying the sale tax, $6.99+$120.49=$127.48

Comparing the two ways,

Physical store= $128.36

Online store=$127.48

Online store will save the most money by ($128.36-$127.48)=0.88

An action movie production team needs glass spheres to hold a green liquid that looks like an explosive l. if all of the availab

Gnesinka [82]

We need 30 glass spheres whose TOTAL volume = 3,392.92 cubic inches.
Therefore each of the 30 spheres must have a volume of 3,392.92 / 30 =
 113.0973333333 cubic inches
Sphere Volume = 4/3 • π • r³
radius^3 = Sphere Volume / (4/3 • π)
radius^3 = 113.0973333333 / 4.1887902048 
radius^3 = 26.9999994758 
radius = 3 inches
diameter = 6 inches
