Answer:

597

Step-by-step explanation:

888 - 291 = ?

888 - 300 = 588

Subtracting 300 is 9 too many, so Gillian should add 9 back

588+9 = 597

Answer: So we start with 888 -291.

Gillian does 888 - 300 = 588. so what she did there is round the 291 up to 300.

So the next steph would be make 588 - 9 = 581.

A better way to write this is

888 - 291 = 888 - 291 + 9- 9 = 888 - 300 -9 = 581.

In this equations always is useful to round up or down some number so its more easy the equation, en then subtract or sum the correspondent number.

Answer: Exponential decay model:

y

=

x

(

1

−

r

)

t

, half life of tablet is about

2

hours and after

t

=

3

hours , remaining drug on patient's system is

42.875

mg.

Step-by-step explanation: Initial drug

x

=

125

mg ; rate of decay

r

=

30

100

=

0.3

gm/hour

Exponential model:

y

=

x

(

1

−

r

)

t

=

125

(

1

−

0.3

)

t

=

125

⋅

0.7

t

Half life:

y

=

125

2

=

62.5

mg

∴

62.5

=

125

⋅

0.7

t

or

0.7

t

=

1

2

. Taking logarithm on both sides we get ,

t

log

(

0.7

)

=

log

(

0.5

)

∴

t

=

log

(

0.5

)

log

(

0.7

)

≈

The half life of tablet is about

2

hours.

After

t

=

3

hours , remaining drug on patient's system is

y

=

125

⋅

0.7

t

=

What is the answer to this problem? 0.35 + 0.27 = ?
gavmur [86]
Have you never added 2-digit numbers?
35 +27 = (30 +20) +(5 +7) = 50 +12 = 62

35/100 +27/100 = (35 +27)/100 = 62/100
0.35 +0.27 = 0.62

The basic idea, taught in 3rd grade, is to line up the decimal points of the numbers, add enough zeros on the right to make the numbers all have the same number of digits to the right of the decimal point, then add in the usual way. The sum has the decimal point aligned with the rest of the numbers.
