The face of a clock has a circumference of 63 in. What is the area of the face of the clock?

Answers

Answer 1

Answer:

Answer:

The area of the clock $= 315.41\ inch^(2)$

Step-by-step explanation:

We have been given the face of the clock that is $63\ in$

So that is also the circumference of the clock.

Since the clock is circular in shape.

So $2\pi(r)=63\ inch$

From here we will calculate the value of radius $(r)$ of the clock that is circular in shape.

Then $2\pi(r)=63\ inch =(63)/(2\pi) = 10.02\ in$

Now to find the area of the clock we will put this value of (r) in the equation of area of the circle.

Now $\pi (r)^(2)=\pi(10.02)^(2)=315.41\ in^(2)$

So the area of the face of the clock = $315.41\ in^(2)$

Julian bought 3.9 liters of cranberry juice, and Jay bought 8.74 liters of apple juice. the mixed the two juices togather, and then poured them equally into 2 bottles. how many liters of juice e are in each bottle?

Answers

The capacity of each bottle is $\boxed{\bf6.32{\text{ liters}}}$ .

Further explanation:

Given:

Julianbought 3.9liters of cranberry juice.

Jay bought 8.74 liters of Apple juice.

They mixed both the juice equally.

Procedure:

1. First find total capacity of both the juice.

2. Now, divide by 2 to find weight of juice in each bottle.

Calculation:

The total juice (in liters) can be obtained by adding both the juice brought by the Julian and Jay.

$\boxed{8.74+3.9=12.64}$

Therefore, the total juice (in liters) is 12.64 liters.

To obtain the number of liters in each bottle can be obtain by divide the total juice in liter by 2.

$\frac{{12.64}}{2}=6.32$

Therefore the capacity of each bottle of juice is 6.32 liters.

Thus, the capacity of each bottle is $\boxed{\bf6.32{\text{ liters}}}$ .

Method 2:

Simple Method:

The Average of two juices gives the value of number of liters in each bottle.

The average is defined as the sum of the items divide by the number of items.

$\begin{aligned}\frac{{8.74+3.9}}{2}&=\frac{{12.64}}{2}\n&=6.32\n\end{aligned}$

Thus, the capacity of each bottle is $\boxed{\bf6.32{\text{ liters}}}$ .

If two adults and three children go to the movies, it costs $31.50. If one adult and five children go to the movies, it costs $35.00. What is the cost of one adult movie ticket? $5.50 $6.50 $7.50

Answers

The adult ticket would cost $7.50

Answer:

The kids is 5.50 adult is 7..50

Step-by-step explanation:

we create an equation

2x + 3y =31.50

and

1x + 5y=35.00

1x is just x so we subtract 5y from both sides

x= 35.00-5y

fill x with 35.00-5y

2(35.00 - 5y) + 3y = 31.50

70.00 - 10y +3y = 31.50

-10y + 3y = -38.50

-7y=-38.50

-7y/-7= -38.50/-7

y=5.50

33.52 is what percent of 8

Answers

The Solution for 33.52 is 419% of 8.

Since we know that percent shows per 100 (since cent means 100), thus we will first divide the whole part into 100 parts and then multiply it with b so that we collect b items per 100 items(that is exactly what b percent means).

100% / x% = 8 /33.52

(100/x)*x =(8/33.52)*x

Here we multiply both sides of the equation by x

100=0.238663484487x

Now we divide both sides of the equation by (0.238663484487) to get x

100/0.238663484487=x

419=x

x=419

now we have, 33.52 is 419% of 8

1. We assume, that the number 8 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 8, so we can write it down as 100%=8.
4. We know, that x% equals 33.52 of the output value, so we can write it down as x%=33.52.
5. Now we have two simple equations:
1) 100%=8
2) x%=33.52
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=8/33.52
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 33.52 is what percent of 8

100%/x%=8/33.52
(100/x)*x=(8/33.52)*x - we multiply both sides of the equation by x
100=0.238663484487*x - we divide both sides of the equation by (0.238663484487) to get x
100/0.238663484487=x
419=x
x=419

now we have:
33.52 is 419% of 8
