fgiga [73]

Answer:

5.66 years

Step-by-step explanation:

450 x 1.025^(n) = 450 + 67.50

450 x 1.025^(n) = 517.50

1.025^(n) =(517.50 / 450)

1.025^(n) = 1.15

n = ln(1.15) / ln(1.025)

n = 5.66

Sergei runs a bakery. He needs at least 175 kilograms of flour in total to complete the holiday orders he's received. He only ha

aliya0001 [1]

Answer:

Kindly check explanation

Step-by-step explanation:

Kilogram of flour needed to complete holiday order is atleast 175kg

Number of kilograms available = 34kg

Flour comes in bags each contain 23kg of flour

He wants to buy the smallest number of bags as possible and get the amount of flour he needs.

Let F = number of bags of flours Sergei needs to buy

F = (total number of kilograms needed - number of kilograms available) / kilograms per bag

F = (≥ 175 - 34) / 23

F = ≥ 141 / 23 = ≥ 6.1304347

Since flour is purchased per bag, the smallest number of bags he can possibly buy and still get the amount of flour he need = 7 bags

Two trains leave stations 306 miles apart at the same time traveling toward each other one is traveling at 90 mph the other at 8

Sergeu [11.5K]

Answer:

They will meet in 1.8 hours.

Step-by-step explanation:

Given that, distance between trains = 306 miles

Let they take time $'t'$ to meet each other.

Speed of first train = 90 mph

Speed of second train = 80 mph

Let distance traveled by first train = $D_1$ miles

Formula for distance:

$Distance = Speed \times Time$

Distance traveled by first train, $D_1 = 90t$

Let distance traveled by first train = $D_2$ miles

Formula for distance:

$Distance = Speed \times Time$

Distance traveled by first train, $D_2 = 80t$

Total distance traveled is 306 miles.

i.e.

$D_1+D_2=306\\\Rightarrow 90t +80t=306\\\Rightarrow 170t=306\\\Rightarrow t =\dfrac{306}{170}\\\Rightarrow \bold{t=1.8\ hr}$

They will meet in 1.8 hours.
