Answer: 6

Step-by-step explanation:

The slope of ST is

$\frac{-5-0}{0-(-6)}=-\frac{5}{6}$

The slope of UV is

$\frac{y-1}{-9-(-3)}=\frac{y-1}{-6}$
Since parallel segments have the same slope,

$-\frac{5}{6}=-\frac{y-1}{6}\\\\5=y-1\\\\y=6$

Each cell divides to form two new cells every 30 minutes. If a culture starts out with exactly 100 bacterial cells how many bact

adelina 88 [10]

So, after 30 mins we have:

100*2

After 1 hour: 100*2*2, etc

the number of 2s will be the number of time they will divide: 3 hrs divided by 0.5 hour: this is six times.

So the final number of cells will be:

$100* 2^{6} =100 *2*2*2*2*2*2= 100 *8*8=100 *64=6400$

So after 3 hrs there will be 6400 cells there!

Meghan has two less dimes as she does nickels and one more than double the amount of quarters as she does nickels for a total of

defon

Answer:

The number of nickel = 3

Number of dime = 1

Number of quarter = 7

Step-by-step explanation:

Let us assume the number of nickels Meghan has = m

So, the number of dimes she has = m -2

And the number of quarters she has = 1 + 2 m

Now, the total amount she has = $2.00

1 nickel = $0.05 ⇒ m nickel = m ($0.05) = 0.05 m

1 dime = $0.10 ⇒ (m -2) dime = m-2 ($0.10) = 0.10 (m-2)

1 quarter = $0.25 ⇒ (1+ 2m) quarter = (1+ 2m) ($0.25) = 0.25 (1+2m)

So, according to the question:

Amount of (nickel + dime + quarter) = $2.00

⇒ 0.05 m + 0.10 (m-2) + 0.25 (1+2m) = 2

or, 0.05 m + 0.10 m - 0.20 + 0.25 + 0.5 m = 2

or, 0.65 m = 2 - 0.05

or, m = 1.95/0.65 = 3

or, m = 3

Hence, the number of nickel = 3

Number of dime = m -2 = 3-2 = 1

and Number of quarter = 2m + 1 = 7
