Answer:

45 times 4/9 times three-fifths

Step-by-step explanation:

4/9 of the 45 questions are done at a rate of 3/5 of a minute. If he finished 5/9 of the 45 then he has 4/9 of the 45 left and the 3/5 of a minute would be continued in the 4/9 of the 45.

C) 2/9 , because dividing both 8 and 36 by 4 will leave the numerator as 2 (8/4=2) and the denominator as 9 (36/4=9).

A bacteria cell splits into two cells every hour. Write and evaluate an exponential expression to find how many cells there will
ryzh [129]
Easy

equation is
f(x)=2ˣ

where x=number of hours elapsed

after 6 hours
f(6)=2⁶=64 bacteria


to solve for 1024

1024=2ˣ
take ln of both sides
ln(1024)=ln(2ˣ)
ln(1024)=x(ln(2))
divide both sides by ln(2)
ln(1024)/ln(2)=x
using calculator
10=x

or you could recognize that
1024=2¹⁰
or keep divising 1024 by 2


10 hours for 1024 bacteria

What is the average (with 0 decimal places) across all schools for the total score? Group of answer choices 1287 1215 1221 1229
Irina18 [472]

Answer:

See explanation

Step-by-step explanation:

Required

The average

The data whose average is to be calculated are not given.

However, the formula to calculate the average is:

\bar x = \frac{\sum x}{n}

Assume the data is:

1287\ 1215\ 1221\ 1229

This means that the number of schools is 4

So:

\bar x = \frac{1287+ 1215+ 1221+ 1229}{4}

\bar x = \frac{4952}{4}

\bar x = 1238

<em>The average of the assumed data is 1238</em>
