What is the final amount if 1584 is decreased by 18% followed by a 19% increase?

Oksi-84 [34.3K]

Answer:

$1,545.67$

Step-by-step explanation:

step 1

if 1,584 is decreased by 18%

we know that

$100\%-18\%=82\%=82/100=0.82$

Multiply the number by 0.82

$1,584(0.82)=1,298.88$

step 2

The number 1,298.88 is increased by a 19%

we know that

$100\%+19\%=119\%=119/100=1.19$

Multiply the number by 1.19

$1,298.88(1.19)=1,545.67$

The answer to this question. i’m confused and don’t understand it.

Georgia [21]

Answer:

5,120 bacterias

Step-by-step explanation:

Given the amount of bacteria after x hours modelled by the equation:

f(x) = 20(2)^x/12

Note that x is in hours not days

To calculate the number of bacteria that will be contained within the culture after 4 days, we will first convert 4days into hours since x is in hours.

24hours = 1day

xhours = 4days

x = 24×4

x = 96hours

Substituting x = 96 into the equation

f(96) = 20(2)^96/12

f(96) = 20(2)^8

f(96) = 20×2^8

f(96) = 20×256

f(96) = 5,120

The number of bacteria that will be contained after 4days is 5,120bacterias

The ratio of the number of apples to the number of pears in a basket was 3:5. After 7more apples were added to the basket and 9

atroni [7]

Answer:

Apples = 24

Pears = 40

Step-by-step explanation:

Let u be the unit of fruit in the basket,

number of apples: $3u +7$

number of pears: $5u -9$

now to find u, we equate the two equations.

$3u+7=5u-9$

Now simplify.

$5u-3u=7+9$

$2u=16$

$u=8$

Now we can find the original number of apples and pears by substituting u.

so original number of apples = $3u = 3(8) = 24$

and original number of pears = $5u = 5(8) = 40$
