Correct Answer
C.Explanation
The fraction of boys can be found by dividing the number of boys (12) by the total number of students (20). So, the fraction of boys is 12/20, which can be simplified to 3/5.Rate this question:

Correct Answer
C. 4x - 3Explanation
The given expression is 7x + 5 - 8 - 3x. To simplify this expression, we can combine like terms. The x terms are 7x and -3x, which can be combined to give 4x. The constant terms are 5 and -8, which can be combined to give -3. Therefore, the simplified expression is 4x - 3.Rate this question:

Write these numbers in order starting with the smallest: 2.303 2.3 2.33 2.03 ________, ________, ________, ________
Correct Answer
2.03
2.3
2.303
2.33Explanation
When comparing decimals, start by looking at the whole number part. In this case, all the numbers have the same whole number part (2).
Next, compare the tenths place. 2.03 has a 0 in the tenths place, making it the smallest.
Then, compare the hundredths place. 2.3 and 2.303 both have a 3 in the hundredths place, but 2.3 has an implied 0 in the thousandths place, while 2.303 has a 3. This makes 2.3 smaller than 2.303.
Finally, 2.33 is the largest as it has a 3 in both the tenths and hundredths place.Rate this question:

There are 25 counters in a bag.12 are red, 5 are green and the rest are white.A counter is chosen at random.Work out the probability that it is white. Give your answer as a percentageP(white) = ________%
Correct Answer
32Explanation
The probability of choosing a white counter can be calculated by dividing the number of white counters by the total number of counters. Since there are 25 counters in total and 12 are red and 5 are green, the remaining counters must be white. Therefore, the probability of choosing a white counter is 8/25. To express this as a percentage, we can multiply this fraction by 100, resulting in 32%.Rate this question:

110 students go on a school trip.Each student needs a bottle of water.How many of these packs are needed?Answer: ________ packs
Correct Answer
19Explanation
To find the number of packs needed, we divide the total number of students (110) by the number of students that can fit in each pack (1). This gives us the answer of 110 packs. However, since the answer format is specified as "packs," we round up to the nearest whole number, which is 19. Therefore, 19 packs are needed to accommodate all 110 students on the school trip, with each student having a bottle of water.Rate this question:

AB is a straight line.Work out the size of angle x.x = ________o
Correct Answer
112Explanation
Since AB is a straight line, the sum of the angles around point B must be 180 degrees. Angle x is opposite to the angle of 112 degrees, so it must also be 112 degrees in order for the sum of the angles to be 180 degrees.Rate this question:

A (3, 5), B (0, -3) and C (-5, 2) are three points.What type of triangle is ABC?
- A.
Isosceles
- B.
Equilateral
- C.
Right-angled
- D.
Scalene
Correct Answer
A. IsoscelesExplanation
An isosceles triangle is a triangle that has two sides of equal length. In this case, we can calculate the lengths of the sides AB, BC, and AC using the distance formula. By calculating the distances, we find that AB = 5, BC = 5, and AC = 8. Since AB and BC have the same length, the triangle ABC is isosceles.Rate this question:

Solve 4x - 5 = 17x = ________
Correct Answer
5.5, 11/2Explanation
The equation 4x - 5 = 17x can be solved by isolating the variable x. We start by subtracting 17x from both sides of the equation to get -13x - 5 = 0. Then, we add 5 to both sides to get -13x = 5. Dividing both sides by -13 gives us x = -5/13. Therefore, the correct answer is x = -5/13, which can also be written as a decimal approximation, x ≈ -0.38.Rate this question:

Jon has 78pNat has £3.52Nat gives Jon some money so that they both have the same amount.How much does Nat give Jon?Answer : £________
Correct Answer
1.37Explanation
To find out how much money Nat gives Jon, we need to calculate the difference between their amounts. Jon has 78p, which is equivalent to £0.78. Nat has £3.52. The difference between their amounts is £3.52 - £0.78 = £2.74. Therefore, Nat gives Jon £2.74 to make their amounts equal.Rate this question:

A cinema has 37 rows of seats23 seats in each row.Adult tickets are £8 each.Child tickets are £6 eachThe cinema has sold tickets for every seat.200 child tickets were sold.Work out the exact amount of money raised.Answer: £________
Correct Answer
6408Explanation
The cinema has 37 rows with 23 seats in each row, so the total number of seats in the cinema is 37 * 23 = 851 seats. Since the cinema has sold tickets for every seat, this means that a total of 851 tickets were sold. Out of these, 200 were child tickets sold at £6 each, so the total amount of money raised from child tickets is 200 * £6 = £1200. The remaining 651 tickets were adult tickets sold at £8 each, so the total amount of money raised from adult tickets is 651 * £8 = £5208. Adding the money raised from child and adult tickets gives us £1200 + £5208 = £6408. Therefore, the exact amount of money raised is £6408.Rate this question:

Correct Answer
5
6
10Explanation
To find the smallest number of boxes of each item the teacher could buy, we need to find the least common multiple (LCM) of the numbers 12, 10, and 6. The LCM of these numbers is 60. Therefore, the teacher could buy 5 boxes of diaries (5 x 12 = 60), 6 boxes of pencils (6 x 10 = 60), and 10 boxes of rulers (10 x 6 = 60) in order to have the same number of each item.Rate this question:

The scatter graph shows the number of driving lessons and the number of tests neededto pass by 10 people.What proportion of the 10 people passed on their first test? Give your answer as a percentageAnswer: ________%
Correct Answer
30Explanation
The answer is 30%. This can be determined by looking at the scatter graph and counting the number of people who passed on their first test. Out of the 10 people represented in the graph, 3 of them passed on their first test. To calculate the proportion, divide the number of people who passed on their first test (3) by the total number of people (10) and multiply by 100 to get the percentage. Therefore, 3/10 * 100 = 30%.Rate this question:

Strong negative
Correct Answer
A. Strong positiveExplanation
The correlation between two variables is said to be strong positive when there is a strong direct relationship between them. This means that as one variable increases, the other variable also increases consistently. The relationship is strong because the increase or decrease in one variable is highly predictable based on the other variable.Rate this question:
