makkiz [27]

The new height of the water is = 9.34 inches (approx)

Step-by-step explanation:

Given, a rectangular container measuring 20 inches long by 16 inches wide by 12 inches tall is filled to its brim with water.

Let the new height of water level be x inches.

The volume of the container = (20×16×12) cubic inches

                                               =3840  cubic inches

According to the problem,

3840 - (20×16×x) = 850

⇔3840 -320x = 850

⇔-320x =850-3840

⇔-320 x = -2990

\Leftrightarrow x =\frac{2990}{320}

⇔x = 9.34 inches

The new height of the water is = 9.34 inches (approx)

bryan has some 3 cent stamps and some 4 cent stamps. what is the least number of stamps he can combine so the value of the stamp
SashulF [63]

Answer:

The least number of stamps required is 9

Step-by-step explanation:

Let the number of 3 cent stamps be x and 4 cent stamps be y

We have

3x+4y=33

The minimum number is obtained when more  4 cent stamps are used

Here y cannot be greater than 8 since \frac{33}{4}

Substitute y=8

3x+4\times 8=33\\\\3x=1\\\\x=\frac{1}{3}

Not possible since x is not a fraction

Substitute y=7

3x+4\times 7=33\\\\3x=5\\\\x=\frac{5}{3}

Not possible since x is not a fraction

Substitute y=6

3x+4\times 6=33\\\\3x=9\\\\x=\frac{9}{3}\\\\=3

Possible

Hence minimum number of stamps is

=x+y\\\\=3+6\\\\=9

The local Tupperware dealers earned the following commissions last month. What was the mean commission​ earned? Round your answe
kirza4 [7]

Answer:

B. ​$ 3094.01

Step-by-step explanation:

Given observations are,

$2894.21, ​ $1777.15, ​ $2144.77, ​ $4096.37, ​ $4046.29, ​$1786.37, ​ $3296.69, ​ $4086.27, ​ $2784.22

Number of observations = 10,

Sum of the observations = 2894.21​+1777.15​+2144.77​+4096.37​+4046.29​+1786.37​+3296.69​+4086.27​+2784.22​+4027.79 = 30940.13,

Hence,

Mean = \frac{\text{Sum of observations}}{\text{Number of observation}}

=\frac{30940.13}{10}

=3094.013

\approx 3094.01

Option 'B' is correct.
