A drink is mixed in the ratio lemonade : orange : cranberry = 6 : 3 : 2 What fraction is orange?

Answers

Answer:

3/11

Step-by-step explanation:

If we add all the numbers together we get 11.

6 + 3 + 2 = 11

Therefore there are 11 parts altogether in the drink.

Orange is 3 parts out of all, so that means it is 3/11 in fraction-form.

Which of the following are independent events?

randomly choosing a marble from a bag, replacing it, and choosing again reaching into your pocket and pulling out two dimes out of 20 coins

drawing a number from a hat, not replacing it, and then drawing a second number

rolling a number cube, rolling again, and trying to match the first roll

Answers

I believe the second one : drawing a number from a hat, not replacing it, and then drawing a second number

Answer:

The first choice.

Step-by-step explanation:

An independent event is an event where the probability of the event doesn't affect the probability of the other.

Randomly choosing a marble from a bag, replacing it, and choosing again reaching into your pocket and pulling out two dimes out of 20 coins.

- This is an independent event since the probability of the first event doesn't affect the probability of the second event in any way.  

Solve the system.
4x + 3y = 10
9x - 4y= 1

Answers

it’s would be (1,2)

4x+3y=10 <— you solve for x and get x=5/2-3/4y

then substitute the value of x into 9x-4y=1 to get
9(5/2-3/4y)-4y=1

solve the equation for Y
y=2

now sub the value of y into x=5/2-3/4y
x=5/2 - 3/4 times 2

your answer would be x = 1

therefore you get (x,y) (1,2)

After solving the given equations, the value obtained for x and y will be equal to (1, 2).

What is an equation?

Mathematical expressions with two algebraic symbols on either side of the equal (=) sign are called equations.

This relationship is illustrated by the left and right expressions being equal to one another. The left-hand side equals the right-hand side is a basic, straightforward equation.

As per the given equations in the question,

4x + 3y = 10      (i)

9x - 4y = 1        (ii)

Multiply equation (i) by 9 and multiply equation (ii) by 4  

36x + 27y = 90

36x - 16y = 4

A similar term of x will cancel out from here.

y = 86/43

y = 2

Put y = 2 in equation (i)

4x + 3(2) = 10

4x = 4

x = 1

What are rational and irrational numbers and how are radicals related to rational exponents?

Answers

A rational numbers is any number that can be turned into a fraction/ratio. (Ex. 8, 0.75, 1/3). An irrational number is anything that can't be turned into a fraction/ratio. (Ex. Pi, square root of 2). Radicals and rational exponents are related because radicals can be converted into rational exponents.

Answer:

Any number that can be written as a fraction with integers is called a rational number. An irrational number is a number that cannot be expressed as a fraction for any integers. Radicals are related because for irrational numbers they cannot be simplified under the radical and you use a radical on the exponent to cancel it out, hope this helps!

your answer to two decimal places.
3,533.10 quetzals
b. 2,131.02 quetzals
768.31 quetzals
d. 48.75 quetzals

Answers

Answer:

A

Step-by-step explanation:

Charles have 3533.10 quetzals.

What is unit conversion?

It is the conversion of one unit to another unit with its standard conversion.

Examples:

1 hour = 60 minutes

1 minute = 60 seconds

1 km = 1000 m

We have,

Charles allocated amount for spending = $415.

The exchange rate from US dollars to Guatemalan quetzals.

= 1 : 8.5135

This means,

$1 = 8.5135 quetzals

Now,

$1 = 8.5135 quetzals

Multiplying 415 on both sides.

$415 = 415 x 8.5135

$415 = 3533.1025 quetzals

Rounding to two decimal places.

$415 = 3533.10 quetzals.

Thus,

Charles has 3533.10 quetzals.
