HALP PLeAASE i will give brainly ;D

a_sh-v [17]

Answer:

the total amount is £756.

Step-by-step explanation:

given, monthly charge =£16

rate per min of call= £13 per min(150free calls )

rate per texts= £15per text (150 free text)

now, total calls made =170calls

total text = 180 text

now, minimum charge for 150 calls is free

so, left calls = 20 calls

charge for 20 calls= 20×£13

therefore, the charge for 20 calls is £260

now, for text

no. of text = 182-150=32

now, charge for 32 text =£ 15× 32

therefore the charge of 32 text is £ 480.

now, total amount = monthly charge + extra call charge+ extra text charge.

or, total amount = £16+£260+£480

=£756

therefore, the total amount is £756.

hope it helps...

A sample of bacteria is decaying according to a half-life model. If the sample begins with 700 bacteria, and after 10 minutes th

Papessa [141]

Answer:

18 minutes

Step-by-step explanation:

A = A₀ (½)^(t / T)

where A is the final amount,

A₀ is the initial amount,

t is the time,

and T is the half life.

A = 140 when t = 10. Solve for the half life:

140 = 700 (½)^(10 / T)

0.2 = ½^(10 / T)

log 0.2 = (10 / T) log 0.5

10 / T = 2.32

T = 4.31

When A = 40, t is:

40 = 700 (½)^(t / 4.31)

0.057 = ½^(t / 4.31)

log 0.057 = (t / 4.31) log 0.5

t / 4.31 = 4.13

t = 17.8

Rounded to the nearest whole number, it takes 18 minutes.

Find the slope of the line through each pair of points (20,-16),(19-16)

ale4655 [162]

Answer:

Undefined slope.

Step-by-step explanation:

The formula should be y2 - y1 over x2 - x1

Points ( 20,-16 ) and ( 19, -16 )

So ( -16 - ( -16 ) ) over ( 19 - 20 )

0 over -1

The slope is 0. Undefined.
