Do all 6 digits numbers have 6 addenda in their expanded form

stiks02 [169]

No, for example - 6,005,100 = 6,000,000+5,000+100. Hope this helps!!!

Find the length of a rectangular prism having a volume of 60 cubic meters, width of 2 1/2 meters, and height of 3 1/3

Lostsunrise [7]

Answer:

7 1/5 m

Step-by-step explanation:

Find the length of a rectangular prism having a volume of 60 cubic meters, width of 2 1/2 meters, and height of 3 1/3

Volume of a rectangular prism = Length × Width × Height

Length = Volume/ Width × Height

Length = 60 m³/2 1/2 m × 3 1/3 m

Length = 60 m³/8 1/3 m²

Length = 60 m³÷ 8 1/3 m²

= 60 m³ ÷ 25/3 m²

=( 60 × 3/25 )m

= 180/25 m

Length = 7 1/5 m

A scientist is testing a new antibiotic by applying the antibiotic to a colony of 10,000 bacteria. The number of bacteria decrea

artcher [175]

Answer:

3.3 hours.

Step-by-step explanation:

We have been given that a scientist is testing a new antibiotic by applying the antibiotic to a colony of 10,000 bacteria. The number of bacteria decreases by 75% every two hours.

Since number of bacteria is decreasing exponentially, so we will use exponential decay function.

$y=a*b^x$ , where,

a= Initial value,

b = For decay b is in form (1-r), where r is rate in decimal form.

Let us convert our given rate in decimal form.

$75\%=\frac{75}{100}=0.75$

As number of bacteria is decreasing every 2 hours, so number of bacteria decreased in 1 hour will be x/2.

Upon substituting our given values in above formula we will get,

$y=10,000(1-0.75)^{\frac{x}{2}}$

To find the number of hours it will take to for the bacteria colony to decrease to 1000, we will substitute y = 1,000 in our equation.

$1,000=10,000(0.25)^{\frac{x}{2}}$

Let us divide both sides of our equation by 10,000.

$\frac{1,000}{10,000}=\frac{10,000(0.25)^{\frac{x}{2}}}{10,000}$

$0.1=(0.25)^{\frac{x}{2}}$

Let us take natural log of both sides of our equation.

$ln(0.1)=ln((0.25)^{\frac{x}{2}})$

$ln(0.1)=\frac{x}{2}*ln(0.25)$

$-2.302585=\frac{x}{2}*-1.386294$

$x=\frac{-2.302585}{-1.386294}*2$

$x=1.660964*2$

$x=3.3219\approx 3.3$

Therefore, it will take 3.3 hours for the bacteria colony to decrease to 1000.
