Andre can complete 1.5 facts in one second.

Step-by-step explanation:

Given,

Number of multiplication facts completed in 90 seconds = 135

Therefore;

90 seconds = 135 facts

Dividing both sides by 90 to fins the facts per second

\frac{90}{90}\ seconds=\frac{135}{90}\ facts\\\\1\ second = 1.5\ facts

Andre can complete 1.5 facts in one second.

Please help, will give brainliest to first
Lelechka [254]

Answer:

AN = 16 units

Step-by-step explanation:

So we can use the fact that \frac{AN}{FN} =\frac{OR}{FR}

  • Since this is an isosceles triangle, segments FO and FR are both equal to 7

Manipulating the equation above to solve for AN we have AN = \frac{(FN)(OR)}{FR}

  • Substituting in the known values we have AN=\frac{(10)(11.2)}{7} =16

A bacteria culture contains 1500 bacteria initially and doubles every hour. (a) Find a function N that models the number of bact
Tpy6a [65]

Answer: a) N(t)=1500(2)^t

b) 25165824000

Step-by-step explanation:

The exponential equation for growth is given by :-

y= ab^t , where a= initial value , b =multiplicative growth factor and t = time.

Given : A bacteria culture contains 1500 bacteria initially and doubles every hour.

i.e. a = 1500 and b= 2

Then, the function N that models the number of bacteria after t hours will be :

N(t)=1500(2)^t

To find , the number of bacteria after 24 hours , we put t= 24 in above equation , we get

N(24)=1500(2)^{24}\\\\=1500(16777216)=25165824000

Hence, the number of bacteria after 24 hours is 25165824000.
