please answer the following and give a good explanation

The cost of a large single chocolate is $0.25.

Given is that April and bill went to the grocery store to buy chocolate bars. April bought 4 small chocolate bars and 6 large chocolate bars and 3 large chocolate bars. April paid $16.50 and bill paid $11.25.

We can write -

4x + 6y = 16.50                               ... Eq{ 1 }

3x = 11.25                                            ... Eq{ 2 }

On solving the equation, we get -

{x} = 11.25/3

{x} = 3.75

Now, we can write -

4x + 6y = 16.50

4 x 3.75 + 6y = 16.50

6y = 16.5 - 15

6y = 1.5

y = 1.5/6

{y} = 0.25

Therefore, the cost of a large single chocolate is $0.25.

Answer:

Step-by-step explanation:

Answer:

First son receives $15000

Second son receives $8000

Third son receives $7000.

Step-by-step explanation:

Let first son receive $x and deposit it at 7%

Second son receive $y and deposit in 8%

Third son receive $z and deposit in 6%

Now, let's set up equation using the given information.

The second son share is 1000 more than the third son.

So, we can set up equation as

y= 1000+z

First son share is equal the second son and the third son put together.

So, x=y+z

And we can set up equation for total 30000 as

x+y+z=30000

Plug in y as 1000+z and x as y+z

We get third equation as

y+z+1000+z+z=30000

Plug in again y as 1000+z

It gives,

1000+z+z+1000+z+z=30000

Combine like terms,

2000+4z=30000

Subtract both sides 2000

4z=28000

Divide both sides by 4

z=7000

Now, plug in z as 7000 into y=1000+z to get y =8000

Now, x =y+z plug in the y and z values

x= 8000+7000=15000

Let's check with interest,

15000(7%)+8000(8%)+7000(6%)=2110

1050+640+420= 2110

2110=2110.

Yes! The calculations are correct!

Answer: 1/5

Step-by-step explanation:

From the question, we are informed that the gem on the queen's ring weighed 9/10 of a carat and the stone on the princess's ring weighed 7/10 of a carat.

To calculate how heavier the stone on the queen's ring was than the stone on the princess will be:

= 9/10 - 7/10

= 2/10

= 1/5

The idea begin this problem is to solve for the perimeter of the square garden using the expression for perimeter which is

Perimeter of square= 4L

given that the garden wants the side of the square garden to be between 15 and 18 ft long

Say we go with a length of 16ft (you can pick any number in the range just maintain the formula for the perimeter)

perimeter= 4(16)

perimeter= 64ft

now we have to convert ft to yard

1 yard=3ft

x yard=64ft

cross multiply we have

x=64/3

x=21.33 yards

given that a yard cost $1.5, therefore 21.33 yards will cost

=21.33*1.5

=$31.99

Answer:

Your answer is: D) 19.99+0.29m=73.93

We are trying to find the miles driven so therefore 0.29$ is per mile. So we have to see how many 0.29$ along with 19.99$ can fully add up to 73.93$

Step-by-step explanation:

Hope this helped : )

Option C, 1 mile is the correct answer

The displacement is 1 mile.

Given that, Amy runs 2 miles south, then turns around and runs 3 miles north.

Displacement is the change in the position of any point or object. It has a direction and magnitude, so it is a vector quantity. It is shown with an arrow that points from the starting position to the final position.

Now, Amy runs 2 miles south from the fixed point he runs in the north direction for 3 miles.

So, the displacement=1 mile

Therefore, the displacement is 1 mile.

Answer: t = 22x + 50

Step-by-step explanation:

t = total amount earned

x = hours worked

We know his friend payed $50, so that is our initial value. We don’t need hours for that one.

For his job as trainer, he earns $22 per hour but we don’t know how many hours he earned, so that is x. That is how I got the 22x.

Ed's combined distance for the first three days is 38.58 miles.

Given that, Ed ran 12.56 miles on one day, 12.98 miles the second day, and 13.04 miles on the third day.

Decimals are one of the types of numbers, which has a whole number and the fractional part separated by a decimal point. The dot present between the whole number and fractions part is called the decimal point.

The total distance can be determined as follows:

Total distance = 12.56+12.98+13.04

= 38.58 miles

Hence, Ed's combined distance for the first three days is 38.58 miles.

Step-by-step explanation:

Pythagorean Theorem: a² + b² = c²

We use the Pythagorean Theorem to help us solve for missing right triangle side lengths. It is wise to remember this formula.

An example with addition is 3x(20+5) as 20 plus 5 is still 25, and an example with subtraction is 3x(30-5), as 30 minus 5 is 25.

The equation gives only the total vertical distance traveled by the firework or maximum height reached by the firework

Step-by-step explanation:

Given;

A function that models the fireworks vertical distance with no respect to time,x, as;

f(x)=-16x^+96x+112

The equation gives only the total vertical distance traveled by the firework, it does not account for the position of the firework at a particular time.

Thus, with the given function we can only estimate the maximum height reached by the firework.
