for the two triangles

formula=1/2×b×h

=1/2×6×4=12

since there are 2 triangles=12×2=24

for the side rectangles

area=l×b

=7×5=35

since there are 2 rectangles=35×2=70

the rectangle in the middle=7×6=42

now add all of them = 25+70+42=137

Charlie is helping refill ketchup bottles at his uncle's diner. He has a huge container with 2 gallons of ketchup, which he distributes evenly among 15 bottles. How much ketchup goes in each bottle? Write your answer as a proper fraction or mixed number.

Answers

Answer:

A = 2/15 gallons per bottle

Step-by-step explanation:

Given;

Total volume of ketchup V = 2 gallons

Number of bottles N = 15

The amount of ketchup per bottle A;

A = total volume of ketchup ÷ number of bottles

A = V/N

Substituting the values;

A = 2gallons ÷ 15bottles

A = 2/15 gallons per bottle

Answer:

2/15

Step-by-step explanation:

2 divided by 15 is the same or equal to 2/15

example: 2 divided by 15= 2/15

the scale on a map is 1 : 15000 how many kilometers on the ground would be represented by 12 cm on the map?

Answers

Answer:

1.8 km

Step-by-step explanation:

The scale on the map is 1 : 15000.

This means that every 1 cm on the map is equal to 15000 cm on the ground.

12 cm on the map will therefore be:

12 * 15000 = 180000 cm

Let us convert to kilometres:

100000 cm = 1 km

180000 cm = 180000 / 100000 = 1.8 km

12 cm on the map will be 1.8 km on the ground.

Brian & Paul share a lottery win of £7800 in the ratio 1 : 4. Brian then shares his part between himself, his wife & their son in the ratio 1 : 6 : 3. How much more does his wife get over their son?

Answers

Answer:

The wife gets £468 over the son

Step-by-step explanation:

Firstly, we shall calculate the total amount Brian made from from what he and Paul won.

The ratio is 1:4, meaning for every 2 part Brain takes, Paul takes 4

Paul’s share is thus 1/5 * 7800 = 7800/5 = £1560

Now we have another ratio for sharing the amount Brain has at home.

The total ratio here is 1+6+3 = 10

The share of the wife will be 6/10 * 1560 = 6 * 156 = 936

The son share is half of this which is 936/2 = 468

The difference between their shares is £936-£468 = £468

A player tosses a die 6 times.If gets a number 6 Atleast two times he wins 2 dollars ,otherwise he looses 1 dollar.. Find the expectation of the amount if he wins

Answers

Answer:

[tex]E(x)=-0.2101[/tex]

Step-by-step explanation:

The expected value for a discrete variable is calculated as:

[tex]E(x)=x_1*p(x_1)+x_2*p(x_2)[/tex]

Where [tex]x_1[/tex] and [tex]x_2[/tex] are the values that the variable can take and [tex]p(x_1)[/tex] and [tex]p(x_2)[/tex] are their respective probabilities.

So, a player can win 2 dollars or looses 1 dollar, it means that [tex]x_1[/tex] is equal to 2 and [tex]x_2[/tex] is equal to -1.

Then, we need to calculated the probability that the player win 2 dollars and the probability that the player loses 1 dollar.

If there are n identical and independent events with a probability p of success and a probability (1-p) of fail, the probability that a events from the n are success are equal to:

[tex]P(a)=nCa*p^a*(1-p)^{n-a}[/tex]

Where [tex]nCa=\frac{n!}{a!(n-a)!}[/tex]

So, in this case, n is number of times that the player tosses a die and p is the probability to get a 6. n is equal to 6 and p is equal to 1/6.

Therefore, the probability  [tex]p(x_1)[/tex] that a player get at least two times number 6, is calculated as:

[tex]p(x_1)=P(x\geq2)=1-P(0)-P(1) \\\\P(0) =6C0*(1/6)^{0}*(5/6)^{6}=0.3349\\P(1)=6C1*(1/6)^{1}*(5/6)^{5}=0.4018\\\\p(x_1)=1-0.3349-0.4018\\p(x_1)=0.2633[/tex]

On the other hand, the probability [tex]p(x_2)[/tex] that a player don't get  at least two times number 6, is calculated as:

[tex]p(x_2)=1-p(x_1)=1-0.2633=0.7367[/tex]

Finally, the expected value of the amount that the player wins is:

[tex]E(x)=x_1*p(x_1)+x_2*p(x_2)\\E(x)=2*(0.2633)+ (-1)*0.7367\\E(x)=-0.2101[/tex]

It means that he can expect to loses 0.2101 dollars.

Answer:

Expected value = -0.2101

Step-by-step explanation :

Givena discrete variable the expected value is given as:

E(x) = xp(x) + yp(y)

Where x and y are the values the variables can assume, and p(x) and p(y) are their respective probabilities.

Probability that a player gets 6 at least twice = p(x ≥ 2) = 1 - p(x≤ 2)

= 1 - p(0) - p(1)

But p(0) = 0.3349

p(1) = 0.4018

p(x ≥ 2) = 1 - 0.3349 - 0.4018

= 0.2633

p(y) = 1 - p(x)

= 1 - 0.2633

= 0.7367

Expected value = 2(0.2633) + (-1)(0.7367)

= -0.2101

A loss of $0.2101 is expected.

Jeremy is driving to his friends house that is 60 miles away from his home the scale on Jeremy's map is 1 1/2 inches equivalent to 9 miles how far is it on the map from jeremys house to his friends?

Answers

Answer:

The distance between their house on the map is 10 inches.

Step-by-step explanation:

In order to calculate the distance from Jeremy's friend house to his we can apply a rule of three in a way that 60 miles is related to "x" inches in the same proportion as "1 1/2" inches is related to 9 miles. Before applying that it'll be for the best if we convert the mixed fraction to a pure fraction as shown below:

[tex]d = 1\frac{1}{2} = 1 + \frac{1}{2} = \frac{2}{2} + \frac{1}{2} = \frac{3}{2}[/tex]

Creating the rule of three:

[tex]\frac{60}{9} \frac{\text{miles}}{\text{miles}} = \frac{x}{\frac{3}{2}} \frac{\text{inches}}{\text{inches}}\\\\9*x = \frac{60*3}{2}\\\\x = \frac{180}{18}\\\\x = 10 \text{ inches}[/tex]

The distance between their house on the map is 10 inches.

A rope is cut so that one piece is three times the length
of the other. Each rope is then used to enclose an area
in the shape of an equilateral triangle. If the area
enclosed by the shorter rope is 1,000 m2, what is the
area enclosed by the longer rope?

Answers

Answer:

9,000 m2

Step-by-step explanation:

If the longer rope has three times the length of the shorter rope, the perimeter and the sides of the triangle formed by the longer rope are three times the perimeter and sides of the triangle formed by the smaller rope.

The area of an equilateral triangle is:

[tex]Area = \frac{side^{2} * \sqrt{3}}{4}[/tex]

So, if the side is three times bigger, the area will be 9 times bigger (3^2).

The area of the small triangle is 1000 m2, so the area of the bigger triangle is 9 * 1,000 = 9,000 m2

Eddie had lunch at 10 minutes to 1 in the afternoon.
Fatimah had lunch at 11 45 on the same day.
Who had lunch later? How much later?​

Answers

Answer: Eddie had lunch later than Fatimah.

Step-by-step explanation: Eddie had lunch at 10 minutes to one, which is 12:50. Fatimah had lunch at 11:45. So if you subtract 11:45 from 12:50, you find that Eddie had lunch 1:05 later than Fatimah.

Answer:

Eddie had lunch later.

He had lunch 1 hour 5 minutes later

Step-by-step explanation:

Eddie had lunch 10 min before 1

which means at 12 50.

Fatimah had lunch at 11 45 . Earlier than Eddie.

Eddie had lunch after her.

and How much later?

11 45 to 12 45 is 1 hour.

12 45 plus 5 minute is 12 50.

so it is 1 hour 5 minute

Question 3: Marla bought one necklace and two bracelets for $67.50. Use the following information to determine the amount she paid for each bracelet: The price of the necklace was $27. The bracelets were both the same price. Enter your numerical answer only in the box; do not include the dollar sign.

Answers

Answer:

Each bracelet costs 20.25

Step-by-step explanation:

Here's what was given in the equation:

Total Price: $67.50

Price of necklace: $27

We can subtract the $27 from the $67.50 to get $40.5

Since we know that both bracelets are the same price we can divide the $40.5 by 2 to get two of the exact same prices. The result is $20.25 for each bracelet.
