Solution:

<u>Step-1: Find the volume of the rectangular prism.</u>

  • Volume of rectangular prism: LBH
  • => Volume of rectangular prism: (10)(2)(3 1/2)
  • => Volume of rectangular prism: (10)(2)(3.5)
  • => Volume of rectangular prism: (2)(35)
  • => Volume of rectangular prism: 70 in³

<u>Step-2: Find the volume of the small cube.</u>

  • Volume of cube: L³
  • => Volume of cube: (1/2)³
  • => Volume of cube: (1³/2³)
  • => Volume of cube: (1/8)

<u>Step-3: Divide.</u>

  • 70 ÷ 1/8
  • => 70 x 8
  • => 560 cubes

Thus, 560 cubes are needed to fill the rectangular prism.

Why can't you compare 5 minutes in 240 seconds without making some kind of change
grin007 [14]
You have to have the same unit of measure. Here your units are "minutes" and "seconds". In order to compare the two, you must change to 240 seconds into minutes (dividing by 60 = 4 mins) OR change the 5 minutes into seconds (multiply by 60 to give you 300 seconds)

What is the value of log279?<br> -3/2, -2/3, 2/3, 3/2
kaheart [24]

Answer:

2/3

Step-by-step explanation:

log27(9)

Factor the number: 27=3³

= log3³(9)

Apply log rule: loga^b(x) - 1/b loga(x).

log3³(9) =1/3 log3³(9)

=1/3 log3³(9)

Factor the number: 9=3²

=1/3 log3³(3²)

Apply log rule: loga(a^b) =b

log3 (3²) =2

1/3×2

=2/3

Smart enough to answer this question? Gracie, Mary, and Nancy each have a small collection of seashells. Gracie has 5 more than
adelina 88 [10]
X = mary's shells
g = 1 1/4x + 5
n = 1 1/2x+ 1
g = n

1 1/4x + 5 = 1 1/2x + 1
5/4x + 5 = 3/2x + 1...multiply by common denominator of 4, this will get rid of fractions...however, this is optional...u can work with fractions if u wish.
5x + 20 = 6x + 4
5x - 6x = 4 - 20
-x = - 16
x = 16....so Mary has 16 shells

Since the shape is a square, it has 90° angles.

if cut in half, it creates a 45-45-90 triangle.
using this, you can use the ratio of 1:sqrt2 to find x. so the ratio would be x:6 to 1:sqrt2.

divide 6 by sqrt2 to find x, and then rationalize for it to become 6sqrt2/2, which would simplify even further to 3sqrt2
