Bob bought 16 packs of cola. Each pack had 8 cans. He drank 9 of the cans. How many cans are left?

grin007 [14]

Answer:

119 Cans Left

Step-by-step explanation:

If bob brought 16 packs of soda, and each pack had 8 cans, there would be 128 cans. This is because 1 pack is worth 8 cans.

16 × 8 = 128

128 - 9 = 119

Bob drank 9 of the cans, which is the same as subtracting from 128. This gives us the answer.

The formula for velocity of an object is the equals d over t where he is a velocity of the object t is the distance traveled and

butalik [34]

Answer:

$(a)\ t =\frac{d}{v}$

$(b)\ d = vt$

Step-by-step explanation:

The question is mixed up with details of another question. See comment for original question

Given

$v = \frac{d}{t}$

$v \to velocity$

$d \to distance$

$t \to time$

Solving (a): Solve for time

We have:

$v = \frac{d}{t}$

Cross multiply

$t * v = d$

Make t the subject

$t =\frac{d}{v}$

Solving (b): Solve for distance

We have:

$v = \frac{d}{t}$

Cross multiply

$d = v * t$

$d = vt$

How do you determine whether you are finding a percent of increase or a percent of decrease between two values? Explain.

Slav-nsk [51]

Answer:

Increase:

It will have increase when y>x

so, percentage of increase is

$=\frac{y-x}{x}\times 100$

Decrease:

It will have decrease when x>y

so, percentage of decrease is

$=\frac{x-y}{x}\times 100$

Step-by-step explanation:

Let's assume initial value as x

assume final value as y

Increase:

It will have increase when y>x

so, percentage of increase is

$=\frac{y-x}{x}\times 100$

For example:

Initial value is 40

So, x=40

Final value is 50

so, y=50

now, we can find percentage in increase

$=\frac{50-40}{40}\times 100$

$=25$

Decrease:

It will have decrease when x>y

so, percentage of decrease is

$=\frac{x-y}{x}\times 100$

For example:

Initial value is 50

So, x=50

Final value is 40

so, y=40

now, we can find percentage in decrease

$=\frac{50-40}{40}\times 100$

$=25$
