Sam is eating a Big Hamburger. The first bite was 20% of the Hamburger, the second bite was 20% of what is left and so every next bite is 20% of what is left.
a) How much did the Hamburger weigh originally, if after the second bite there was 160g of it left?

Answers

Answer:

250g

Step-by-step explanation:

To calculate the original weight, you just have to find how much was left of the hamburger after the second bite.

Say that the hamburger is x grams.

0.64x = 160

x = 250

I feel sorta bad but, I got pretty much the same answer...

Answer:

The sum of two positive integers is 12. When the smaller integer is subtracted from five times the larger, the result is 36. Find the two integers.

Answers

Answer:

The smaller integer is 4 and larger integer is 8 .

Step-by-step explanation:

First we have to form own variables and expression. So we let the smaller integer be x and the larger integer be y. Next using the information given to form expressions :

[tex]x + y = 12 \\ 5y - x = 36[/tex]

Lastly, we can solve the simultaneous equation using Elimination :

[tex]x + y = 12 - - - (1)[/tex]

[tex] - x + 5y = 36 - - - (2)[/tex]

[tex](1) + (2)[/tex]

[tex]x + ( - x) + y + 5y = 12 + 36[/tex]

[tex]6y = 48[/tex]

[tex]y = 8[/tex]

[tex]sub \: y = 8 \: into \: (1)[/tex]

[tex]x + 8 = 12[/tex]

[tex]x = 4[/tex]

"Suppose that 5% of bags contain forbidden items."
Forbidden

Not forbidden
What is the probability that a randomly chosen bag does NOT contain a
forbidden item?
P(not forbidden) =

Answers

Answer:

.95 is the correct answer. See screenshot below

Step-by-step explanation:

The probability that a randomly chosen bag does NOT contain a forbidden item is 0.95

What is probability?

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.

Given that, 5% of bags contain forbidden items.

We know that, the probability of an event not happening is 1 minus the probability of the event happening,

Therefore, the probability that a randomly chosen bag does NOT contain a forbidden item = 1-0.05 = 0.95

Hence, the probability that a randomly chosen bag does NOT contain a forbidden item is 0.95

If your car gets 22 miles per​ gallon, how much does it cost to drive 360 miles when gasoline costs ​$2.80 per​ gallon?

Answers

If you get 22 miles for 2.80 and you need 360 miles

22\360=?•2.80

22/360=16.3

2.80 • 16.3 = 45.6$

So it would cost 45.6$ to drive 360 miles

Answer:

45.6

Step-by-step explanation:

the way you find this would be

22/360 = 16.32.80 x 16.3 = 45.64But to get 45.6 you would have to round this answer to the nearest tenth 45.64 rounded to the nearest tenth would be 45.6Therefore your answer would be $45.6 per gallon

A cylinder has a radius of 14 m and a height of 6 m. What is the exact volume of the cylinder? 84π m³ 168π m³ 504π m³ 1176π m³

Answers

Answer:

1176π m³

Step-by-step explanation:

The formula for the volume of a cylinder is:

V = πr²h

Let's substitute the values given into this equation:

V = πr²h

V = (π)(14²)(6)

Solve:

V = (π)(14²)(6)

V = (π)(196)(6)

V = 1,176π

Therefore, the volume of the cylinder is 1176π cubic meters.

Answer:

1176

Step-by-step explanation:

r (radius) = 14 m

h (height) = 6 m

v (volume) = ?

Formula: V=πr2h

We are looking for the volume of the cylinder. We know that the Radius is 14 and the height is 6.

So we need to

1: Radius * 14 * 6

2: Radius * 196* 6

Answer: 1176

A new car sells for $27,500. The value of the car decreases by 14% annually. You want to sell the car when it's worth about $4000. Explain how many years you will keep the car, when you will sell it, and how you determined your answer.

Answers

Answer:

The formula would be:

27500 x (1 - 14/100)^year = 4000

=> (86/100)^year = 4000/27500

=> 0.86^year = 0.145

=> year = log(0.145)/log(0.86) = 12.8

Hope this helps!

:)

Answer:

13 years

Step-by-step explanation:

4000 = 27500 × (1 - 14/100)^t

4000 = 27500 × 0.86^t

0.86^t = 8/55

t ln(0.86) = ln(8/55)

t = 12.78248711
