Mrac [35]3 years ago
3 0

Answer:

X=6

Step-by-step explanation:

From the question we are told that

Length l=2

Height h=3/2

Width w=1

Generally the equation for Volume of the Rectangular prism is mathematically given by

 v=l*h*w

 v=2*\frac{3}{2}*1

 v=3m^3

Therefore the number of half 1/2 inch cube X in v is

 X=\frac{v}{1/2}

 X=6

David invested $1000.ppm what would that money grow to the 18 months at 5.5% interest rate?
yaroslaw [1]
<span>David invested $1000. Let's solve for the amount of money to grow to the 18 months at 5.5% interest rate?
Let's assume that this 5.5% interest is per month.
=> 1 000 dollars * 0.055 = 55 dollars per month
=> 55  * 18 months = 990 dollars in 18 months.</span>

Which of these scales are equivalent to 3 cm to 4 km? select all that apply. recall that 1 inch is 2.54 cm
AlladinOne [14]

Answer:

1. 0.75 cm to 1 km

4. 0.3 mm to 40 m

Step-by-step explanation:

we have the scale

\frac{3}{4}\frac{cm}{km}=0.75\frac{cm}{km}

<u><em>Verify each case</em></u>

case 1) 0.75 cm to 1 km

\frac{0.75}{1}\frac{cm}{km}=0.75\frac{cm}{km}

therefore

The scale is equivalent to the given value

case 2) 1 cm to 12 km

\frac{1}{12}\frac{cm}{km}=0.08\frac{cm}{km}

0.08\frac{cm}{km} \neq 0.75\frac{cm}{km}

therefore

The scale is not equivalent to the given value

case 3) 6 mm to 2 km

Remember that

1 cm= 10 mm

1 mm=0.1 cm

we have

\frac{6}{2}\frac{mm}{km}=\frac{0.6}{2}\frac{cm}{km}=0.30\frac{cm}{km}

0.30\frac{cm}{km} \neq 0.75\frac{cm}{km}

therefore

The scale is not equivalent to the given value

case 4) 0.3 mm to 40 m

Remember that

1 cm= 10 mm  -----> 1 mm=0.1 cm

1 km=1,000 m ----> 1 m=0.001 km

we have

\frac{0.3}{40}\frac{mm}{m}=\frac{0.03}{0.04}\frac{cm}{km}=0.75\frac{cm}{km}

0.75\frac{cm}{km}=0.75\frac{cm}{km}

therefore

The scale is equivalent to the given value

case 4) 1 inch to 7.62 km

Remember that

1 in= 2.54 cm

we have

\frac{1}{7.62}\frac{in}{km}=\frac{2.54}{7.62}\frac{cm}{km}=0.33\frac{cm}{km}

0.33\frac{cm}{km} \neq 0.75\frac{cm}{km}

therefore

The scale is not equivalent to the given value

The function F(x) = 2x/x+3 is an example of a rational function.<br><br><br> True<br> False
PSYCHO15rus [73]

It is true because a rational function is defined as those functions where the variable is placed in the denominator, which must be restricted, because all denominators cannot be equal to zero, other wise it would be undetermined
