Last year Jo paid £245 for her car insurance.
This year she has to pay £883 for her car insurance.

Work out the percentage increase in the cost of her car insurance

(3 marks)

Answers

Answer 1

Answer:

Increase=638/245*100=260.40

Step-by-step explanation:

First: work out the difference (increase) between the two numbers you are comparing.

Increase = New Number - Original Number.

Then: divide the increase by the original number and multiply the answer by 100.

% increase = Increase ÷ Original Number × 100.

The linear function below represents the total cost in dollars, y, to camp at state Park for x nights. What is most likely represented by the y intercept of the function

y=14x +22
a-The number of nights spent camping
B-The cost per night to camp at the park
C-The number of people camping
d- The cost of a one time fee for a camping pernit​

Answers

Answer:

D

Step-by-step explanation:

Since you already know the cost per night and the total cost, you would need to multiply the number of people camping there, therefore, '22' can't be the number of people camping. That makes the final answer D.

is a good one? If there are 800 apples in a basket, how many of them are likely to be good?

Answers

Answer

Step-by-step explanation:

The odds of picking a good one are 5/200 or 0.025.

If there are 800, then the odds are 20/800 or, 0.025

So, most likely there would be  780/800 good ones.

Answer:

97.5%; 780 apples

What is the partial fraction decomposition of
7x squared- 6x +9/
3x(4x squared +9)

Answers

9514 1404 393

Answer:

  1/(3x) =(x -2)/(4x^2 +9)

Step-by-step explanation:

The denominator cannot be factored further, so the final form will be ...

  A/(3x) + (Bx +C)/(4x^2 +9)

The value of this is ...

  (A(4x^2 +9) +(3x)(Bx +C))/(3x(4x^2 +9))

  = ((3B+4A)x^2 +3Cx +9A)/(3x(4x^2 +9))

Equating coefficients gives ...

  3B+4A = 7

  3C = -6   ⇒   C = -2

  9A = 9   ⇒   A = 1

Using the found value of A, we find ...

  3B +4 = 7   ⇒   B = 1

Then the decomposition is ...

  [tex]\dfrac{7x^2-6x+9}{3x(4x^2+9)}=\boxed{\dfrac{1}{3x}+\dfrac{x-2}{4x^2+9}}[/tex]

Every store employee gets an additional 10% off the already discounted price. If an employee buys an item with an original price of $40, how much is the discount? Explain how you got your answer

Answers

Answer:

$44.44444444

Step-by-step explanation:

So as per question employees get 10% discount of the discounted price. So our equation would be considering discounted price = x

=> x- 10x/100 = 40 => 100x-10x/100 = 40 => 90x = 4000 => x= $44.4444

This is for Spanish could someone please help? The fact that I rather help others on here than finish my school work for today *shaking my head* It is paragraph: It is urgent plz help!!In 2011, the population of the world reached seven billion people. The UN Population Division (2015) predicts the number could be as high as 9.7 billion by 2050; that is an extra two billion peoplethe same number of people who currently reside in the African and American continents combined-living on Earth using its resources to survive. This is hard to conceive. 2 Although families are getting smaller, people are living longer because medical and technical advances have lessened the impact of infectious disease. As a result, the UN's worst case scenario for 2100 is that the world population will reach almost 16 billion (UN, 2011). That is more than twice the number of people we have today. And yet already we are placing undue pressure on the Earth. The kind of pressure that, if increased, could have a profound and irreparable effect on our planet.The first fundamental issue is water. Just 2.5% of the world's water is fresh, with much of that caught up in polar ice caps (University of Michigan, 2000). Drought and poor infrastructure mean that already today water is a scarce resource. Over seven hundred million people lack access to clean water (WHO, 2013) and one in three people in every continent do not have enough water to satisfy their daily needs (WHO, 2009). Without clean drinking water, there will be an exponential increase in the incidence of diseases such as cholera and typhoid, which will undoubtedly place an excessive strain on healthcare systems. Without water for agriculture and industry, our food and manufacturing industries will be unable to satisfy demand. Already today, 10% of people consume foods which have been irrigated using waste water full of chemicals or disease (WHO, 2009). Should water become even scarcer, this is likely to grow further.The second critical issue is land. Current agricultural practices and the impact of pollution both contribute to soil erosion and a decreased level of soil fertility. It is estimated such poor quality land affects 1.5 billion people around the world (UNCCD, 2011). Deforestation and mining have had a devastating impact on our ecosystem and the biodiversity on which it thrives. The WWF (n.d.) estimates that we may be losing 10,000 species a year. All of this affects the number of crops that can be grown and produces greater food insecurity. How can we allow such environmental degradation to occur under our noses? 5 Another prime concern is energy. Governments, such as those in Denmark and Germany, are investing in renewable energy to eliminate their reliance on oil and to tap into resources with greater sustainability. However, the number of road vehicles reached one billion in 2010 (WardsAuto, 2011), an increase of 20 million from the previous year, and is continuing to increase due to the growing wealth in developing countries. It is therefore likely that there will be an unprecedented demand for oil over the next 50 years, pushing prices to exorbitant levels. This will make it more difficult for people to afford food, heating, and other manufactured goods, placing more people into poverty.Overpopulation is not a problem for one country or continent; it is a problem for all of us. The UN (2012) estimates that by 2030 the world will need 50% more food, 30% more water, and 45% more energy than it does today. We must stop burying our heads in the sand and make a sustained effort to reduce population growth. We must develop a coherent strategy that will increase access to education for all. Not only is education a fundamental human right, it also facilitates a reduction in population growth. Large families tend to be prevalent in developing countries and yet when men, women, and children in these areas receive education, family sizes shrink. The UN estimates that in less developed countries where women are not educated, they have twice as many children as in those countries where they are educated. It is therefore this area in which we should invest time and money. Who can argue with free and equal education for all?It is true that the world's population is growing, but this is not the cause of our current and future global problems. Believing this will give rise to ignorance of the real problem and the resulting irreparable damage to our planet. 2 Let me start by explaining why overpopulation is a myth. The UN Population Division regularly predicts population growth, but provides a low variant, medium variant, and high variant to factor in various likelihoods. In the 2010 revision, their high variant suggested that the world population will be almost 16 billion in 2100, but the low variant predicted it will peak at 8 billion and decrease to just over 6 billion by 2100. In most cases, it is the low variant that has come true in the past, suggesting the same will be true of their future population predictions. Write the linear inequality shown in the graph.
