Answer:

32

Step-by-step explanation:

Given:

Side of length cube =\frac{1}{6}\text{ inch}

Dimension of rectangular prism,

\text{Length }=\frac{1}{3}\text{ inch}

\text{width }=\frac{2}{3}\text{ inch}

\text{Height }=\frac{2}{3}\text{ inch}

Formula:

\text{Volume of cube }=\text{side}^3

\text{Volume of rectangular box }=\text{Length}\times \text{Width}\times \text{Height}

Calculation:

Now, we fill rectangular prism with cube block and count number of block.

\text{Number of block }=\dfrac{\text{Volume of prism}}{\text{Volume of block}}

\text{Number of block }=\dfrac{\frac{1}{3}\times \frac{2}{3}\times \frac{2}{3}}{\frac{1}{6}\times \frac{1}{6}\times \frac{1}{6}}

\text{Number of block }=32

Hence, The number of block to fill rectangular prism is 32

Volume of one cubic block = (1/6)^3  = 1/216 cu ins

Volume of the prism = 1/3 * 2/3 * 2/3  = 4/27  cu ins

Number of blocks to fill prism  = 4/27 / 1/216   = (216*4) / 27  =  32

Jessica and Mike are making presentations for a class project. Jessica's slideshow starts with a verbal introduction that is 16
uysha [10]

Answer:

they both has 7 slides and the presentation had a duration of 28 seconds

Step-by-step explanation:

we have to setup equation that makes them equal to each other if you know what i mean. 2x+16=3x+10

then we just solve for x

2x+16=3x+10

subtract 10 from each side

2x+6=3x

step 2 subtract 2x from each side

x=6

so both of their presentations are 7 slides long

then to find the length of their presentations we just plug in 6 to one of the equations

2(6)+16

2x6=12 12+16=28 so both of their presentations were 28 seconds

The plans for a shed call for a rectangular floor with a perimeter of 204 ft. The length is two times the width. Find the length
Harlamova29_29 [7]
A-length
b-width
perimeter of rectangular floor: 2a+2b=204
<span>The length is two times the width: a=2b
</span>2a + 2b = 204
2*2b + 2b = 204
6b = 204|:6
b = 34
a=2b=2*34=68

a=68->length
b=34->width

If angle P is a right angle and angle P and Q from a linear pair, then angle Q is
anygoal [31]
< P is a right angle.....a right angle is 90 degrees.
< P and < Q form a linear pair....a linear pair, when added, = 180 degrees

so if < P is 90.....and when added to < Q = 180...
90 + Q = 180
Q = 180 - 90
Q = 90 <== so < Q is also a right angle...measures 90 degrees

Please help 15 points
strojnjashka [21]

Answer:

2

Step-by-step explanation:

2x(5+4)=(_x5)+(_x4)

lets start with 2x(5+4)

(5+4)=9

so we are left with 2x9

2x9=18

so now we have 18=(_x5)+(_x4)

lets try 2 for the blank spaces

18=(2x5)+(2x4)

2x5=10

2x4=8

10+8=18

2x(5+4)=(2x5)+(2x4)

It worked! Hope this helps :)
