Okay here is the math problem..Ivana has 3/4 lbs of hamburger meat. she makes 3 hamburger patties. Each patty weighs the same amount. How much does each hamburger patty weigh?

Answers

Answer 1

Answer:

Answer:

$Weigh\ of\ each\ hamburger\ patty\ is (1)/(4)\ lbs$

Step-by-step explanation:

As given

$Ivana\ has\ (3)/(4)\ lbs\ of\ hamburger\ meat.$

she makes 3 hamburger patties.

Each patty weighs the same amount.

Thus

$Weigh\ of\ each\ hamburger\ patty = (Total\ amount\ of\ hamburger\ meat)/(Total\ number\ of\ hamburger)$

Putting the values in the above

$Weigh\ of\ each\ hamburger\ patty = ((3)/(4))/(3)$

$Weigh\ of\ each\ hamburger\ patty = (1)/(4)\ lbs$

$Therefore\ weigh\ of\ each\ hamburger\ patty\ is (1)/(4)\ lbs$

Answer 2

Answer: Each hamburger weighs 1/4 lbs.
Work:
3/4 divided by 3 equals 3/4 times 1/3 which equals
3/12 simplify it and get 1/4

A model of a rectangular table for a dollhouse is 13 inches long and 8 inches wide. The original table is 52 inches long and 32 inches wide. are the model table and the original table similar figures?

Answers

Hi there, to find if they are similar figures, we have to find if they are the same ratio (fractions). 52 inches and 13 inches equal 52/13, 52÷3=4, the original table is 4 times longer than the model. Now, we have to figure out the width, 32/8 is also 4 because 32÷8=4. The original table is also 4 times wider than the model. So, the two tables are similar.

You buy the same number of brushes, rollers, and paint cans. Write an expression in simplest form that represents the total amount of money you spend forpainting supplies... Brush cost $3.99, Paint cost $21.79 and Paint roller cost $6.89

Answers

If you buy ' N ' of each item, then you'll pay 3.99N for brushes,
21.79N for cans of paint, and 6.89N for rollers.

The question assures us that you bought the same number of
each item. So your total bill at the hardware store checkout is

3.99N + 21.79N + 6.89N

= N (3.99 + 21.79 + 6.89)

= 32.67 N .

A cone has a diameter of 18 in. and a height of 14 in.What is the volume of the cone?
Use 3.14 as an approximation for straight pi . Express your final answer in hundredths.
@sbcardinals

Answers

Answer:

1186.92 in^3

Step-by-step explanation:

Known Variables:

Diameter = 18 in ⇒ Radius = 9

Height = 14 in

Pi = π = 3.14

Known Equation:

Volume of Cone = $\pi r^(2) h / 3$ = 3.14* (9 in)^2 * 14 in / 3 = 1186.92 in^3

The exact solution is attached also (with pi's full digits)

Cone's volume is $V = (1)/(3)Sh$
where S - surface area, h - height
Surface area = $\pi r^2$

r = 18/2=9
h= 14
π = 3.14
$V= (1)/(3) \pi r^2h= (1)/(3) *3.14*9^2*14= (1)/(3) *3.14*81*14=27*14*3.14$ [/tex]
$V = 1186.92$ $in.^3$

How many ml of a 20% acid mixture and a 80% acid mixture should be mixed to get 120ml of a 35% acid mixture?

Answers

Answer:

Volume of Mixture A =90 ml

Volume of Mixture B =30 ml

Step-by-step explanation:

Let say, Mixture A + Mixture B = Mixture C

Volume of Mixture A is x

Volume of Mixture B is y

So, Volume of Mixture C is x+y = 120 ml

Now, Acid contain in Mixture A is 20% =0.2x

Acid contain in Mixture B is 80% =0.8y

Also, Acid contain in Mixture C is 35% =(0.35)(x+y) = 0.35×120=42

Now, we know that,

Acid contain of Mixture A + Acid contain of Mixture B=Acid contain of Mixture C

∴ 0.2x+0.8y=42

∴ 2x+8y=420

We get two linear equations

2x+8y=420 and x+y = 120

Solving above equation...

∴ x=120-y

Replacing x value in 2x+8y=420

∴ 2(120-y)+8y=420

∴ 240-2y+8y=420

∴ 6y=180

∴ y=30

Replacing y value in any equation

∴ x=120-y=120-30=90

∴ x=90

Thus,

Volume of Mixture A is x=90 ml

Volume of Mixture B is y=30 ml
