The ages of Jamal, Wesley, an John are consecutive integers.the sum of thier ages is 108.what are thier ages .

hodyreva [135]

Answer:

Step-by-step explanation:

We have three people

jamal = x (since im guessing hes the youngest)

wesley= x+1

John= x+2

the formula you would use is x+x+1+x+2=108

when you simplify that you get 3X+3=108

you subtract the 3 from 108 which leaves you with 3X=105

divide that by 3 which makes x=35

so

jamal is 35

wesley is 36

john is 37

A store had 50 bottles of olive oil. Each week, 40% of the olive oil bottles were sold and 20 new bottles arrived in shipments.

Wittaler [7]

Answer:

f(n) = f(n − 1) ⋅ 0.6 + 20, n > 0

Step-by-step explanation:

Each week 40% of the olive oil bottles were sold. This means, each week 60% of the bottles were left. In addition to these, 20 new bottles arrived in shipments.

So, every week the number of shipments was:

60% of the shipments of previous week + 20

In equation form this can written as:

Shipments in a week = 60% of shipments of previous week + 20

For, nth week we can re-write this equation as:

f(n) = 60% of f(n - 1) + 20

or

f(n) = f(n - 1) ⋅ 0.60 + 20

For example for first week, replace n by 1 to find the number of shipments in week 1 and same goes for next weeks.

Answer:

53.13

Step-by-step explanation:

To find the measure of an angle use an inverse trig function.

$Sin A = \frac{4}{5}$ so you can take the inverse to find A $sin^{-1}\frac{4}{5} = A$ .

Use a calculator to calculate the value.

A = 53.13
