A family of 2 adults and 3 children went on holiday to Miami.

The family visited a theme park.

They paid a total of 322 dollars to go in.

The exchange rate was £1 = 1.84 dollars.

Change 322 dollars to pounds (£).

Answers

Answer:

£175

Step-by-step explanation:

Given the exchange rate was £1 = 1.84 dollars.

We are to change 322 dollars to pounds (£).

£1 = 1.84 dollars.

x = 322 dollars

Cross multiply

1.84 * x = 322

1.84x = 322

x = 322/1.84

x = 175

Hence 322 dollars in pounds will be £175

Three times a larger number is 30 more than 5 times a smaller number. The sum of the larger number and 5 times the smaller number is 50

Answers

Answer: Smaller number = 6

Larger number = 20

Step-by-step explanation:

Let the smaller number be x.

Let the larger number be y.

Three times a larger number is 30 more than 5 times a smaller number. This will be:

3 × y = (5 × x) + 30

3y = 5x + 30 ...... i

The sum of the larger number and 5 times the smaller number is 50. This will be:

y + 5x = 50 ...... ii

From equation ii

y + 5x = 50.

y = 50 - 5x ...... iii

Put the value of y = 50 - 5x into equation i

3y = 5x + 30

3(50 - 5x) = 5x + 30

150 - 15x = 5x + 30

150 - 30 = 5x + 15x

120 = 20x

x = 120/20

x = 6

The smaller number is 6

Note that y + 5x = 50

y + 5(6) = 50

y + 30 = 50

y = 50 - 30

y = 20

The bigger number is 20

What is the price ofpremium gasoline rounded to the nearestdollar? Rounded to the nearest dime?Rounded to the nearest penny?

Answers

Answer:

$4 (nearest dollar) ;

$4.4 (nearest dime) ;

$4.41 (nearest penny

Step-by-step explanation:

The actual price of premium gasoline is $4.409 per gallon.

A penny = $0.01 or 1 cent

A dime = $0.1 or 10 cent

Price of premium gasoline to the nearest dollar :

$4.409 is rounded to the nearest unit = $4

Price of premium gasoline to the nearest penny : = $4.409 is rounded to the nearest hundredth = $4.41

Price of premium gasoline to the nearest dime : = $4.409 is rounded to the nearest tenth = $4.4

Find the area of each regular polygon. Round to the nearest tenth.

A= _ In2 ?

Answers

Answer:

Area of the square = 225.0 in²

Step-by-step explanation:

Given polygon is a regular polygon that means given quadrilateral has all sides equal in measure.

And a quadrilateral with all sides equal is known to be a square.

Therefore, area of a square = (Side)²

                                              = (15)²

                                              = 225

What does 43/12 is equivalent too?

Answers

Hi there!

Fractions can be equivalent to a lot other fractions...

Explanation:

43/12x2 would be 86/24 so that would be equivalent.

Let do another one..

43/12 when doing this, you can decide to divide or not but this is in the simplest form already so we can just multiply 43 and 12 with anything we want so let do... 5.

So 43 multiply by 5 would be..215 and 12x5 would be 60. So another equivalent fractions that’s the same as 43/12 or we can say 86/24 is 215/60.

I also added how I got the equivalent fractions just in case you don’t understand still...

If an orange is 14cm in diameter.if 3/7 of it is juice,what volume of juice can you get from 5 such oranges.

(Pie=22/7)

Answers

Answer:

3079.5 cm^3

Step-by-step explanation:

We need to find the volume of the orange using the volume of a sphere formula V= 4/3 (π)(r^3). So we plug in the numbers V= 4/3 (22/7) (7^3) and solve. Simple simply the exponent and multiply everything. V= 4/3 (22/7) (343)= 1437 cm^3. Then we take 3/7 from the volume to focus on the juice. 1437(3/7) = 615.9 cm^3. Then multiply by five to find the volume of juice from 5 oranges. 615.9(5)= 3079.5 cm^3

Answers

Sorry need points right now

4n - 8 > n + 17

n > 8.33

This means n is greater than 8.33.

We can have 9, 10, 11, 12, 13, ,,, and so on.

The least value is 9.

The least value of the number of sheep is 9.

What is inequality?

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal =

Greater than and equal=

We have,

Rashid:

Number of sheep owned = n

Bought 17 sheep = n + 17

Eifion:

Number of sheep owned = 4n

Sells 8 sheep = 4n - 8

Eifion still has more sheep than Rashid.

This means,

4n - 8 > n + 17 ______(1)

Solving for n in (1).

4n - 8 > n + 17

Subtract n on both sides.

4n - 8 - n > n + 17 - n

3n - 8 > 17

Add 8 on both sides.

3n - 8 + 8 > 17 + 8

3n > 25

Divide 3 on both sides,

n > 25/3

n > 8.33

This means n is greater than 8.33.

We can have 9, 10, 11, 12, 13, ,,, and so on.

The least value is 9.

Thus,

The least value of the number of sheep is 9.

A Good Day for a Bad DecisionHave you ever noticed that some people always seem to make the right choices? They may be the person who always picks the right pitch to swing at, or the one who always picks the pair of shoes that quickly become a popular fad. On the other hand, some people never seem to make a good decision. They may be the kids who ride a bike down a steep hill and crash into a bush or the ones who step to the edge of a sidewalk in time to get splashed by a car. How do some always seem to be living the good life while others seem doomed to misery? Is this just a matter of luck?While luck probably has something do with it, the better explanation may be that the two groups have differences in the development of their brains. You see, most adult humans use their cerebral cortex to make decisions. The cerebral cortex is the part of the brain in the front of your head that deals with how you perceive the world and respond appropriately. It also helps you control your impulses. This part of the brain is still growing and developing connections well into your adult years. So for young adults and teenagers, the decision-making center of the brain is not completely formed yet.At the same time, the teenage brain is also experiencing growth in another part of the brainthe amygdala (a-mig-dala). This part of the brain is responsible for emotions. Specifically, the amygdala talks to other parts of the brain about events related to rewards and fear.In essence, our emotional brains are having growing spurts and our impulses are out of control at the same time our cerebral cortexes are not finished growing. We simply don't have the tools to control those emotions and impulses. As a result, teenagers feel overly emotional and wishy-washy when it comes to decisions. This development cycle is one reason society doesn't consider children to be adults until after they are 18. Biologically, the teenage brain is not generally ready for adult decisions.So the differences between those who seem to make good decisions and those who seem to make bad ones may be fewer than you think. In fact, if you study the people you think make only good decisions, you will likely find they also make some catastrophically bad ones as well. A person's ability to make a good decision increases with age and experience though we all develop at different rates. While you are young, you may want to take advantage of those around you with bigger cerebral cortexes: adults. Their advice may be just what is needed to counter your amygdala.Which line from the text best states the main idea of the text?
