Answer:

A) 5.4 cm

Step-by-step explanation:

Length of mid segment = (sum of parallel sides )/2

Sum of parallel sides = PQ + SR = 9 + SR

\frac{9+SR}{2}=MN\\\\\frac{9+SR}{2}=7.2 cm\\9 +SR = 7.2*2\\\\9 + SR = 14.4\\       SR = 14.4 -9 \\SR = 5.4 cm

A bacteria culture doubles twice a day. There are 143,622 bacteria present on day 15. How many were present on day 10?
gtnhenbr [62]

Answer:

140

Step-by-step explanation:

- 143,622 bacteria present on day 15

- the bacteria doubles twice a day

that means each day backwards, the bacteria is four times less the day before

therefore:

- on day 14, the number of bacteria is 143,622 / 4

which is 35,905.5

and so on!

so:

- day 13 = 8,976.375

- day 12 = 2,244.09375

- day 11 =  561.0234375

- day 10 = 140.255859375

this rounded to the nearest whole number is

= 140 bacteria

(you can't have a part of a bacteria!)

hope this helps! :)

Harry took a loan from the bank.
Pie

Answer:

The size of Harry's loan is $9000.

Step-by-step explanation:

D(t) models Harry's remaining debt, in dollars, as a function of time t, in months  that is given by :

D(t) =-200t+ 9000

We can see 200 is in negative that means it is getting deducted from the function. So, Harry must be paying this each month against his loan.

Lets put t = 0, that shows no payments have been made.

This will get the amount of loan, before any payments.

D(t)=-200(0)+9000

So,D(t) =9000

Hence, the size of Harry's loan is $9000.
