Rename 4 thousands 7 hundred = 47
The correct renaming of “4 thousands 7 hundred” is 4700. Explanation: “4 thousands” means 4 × 1000 = 4000, and “7 hundred” means 7 × 100 = 700. Adding these together gives 4000 + 700 = 4700. The number 47 is much smaller and does not correspond to the sum of these values. Steps: Convert […]
Michael, the art elective programme student, is working on another assignment. He designs a rectangular pattern measuring 45 mm by 42 mm. He is required to use identical rectangular patterns to form a square. The maximum area of the square allowed is 1.6m^2. (i) How many patterns does he need to form the smallest square? (ii) What are the dimensions of the largest square that he can form?
Answer: (i) 36 patterns (ii) 126 mm by 126 mm Explanation: This problem involves concepts from geometry and optimization, specifically focusing on maximizing the area of a square within a rectangular grid pattern. The key idea is to determine how many smaller patterns (rectangles) can be arranged to form the smallest possible square, and what […]
Which formula/name pair is incorrect? A) FeSO4 iron(II) sulfate B) Fe2(SO3)3 iron(III) sulfate C) FeS iron(II) sulfide D) FeSO3 iron(II) sulfide E) Fe2(SO4)3 iron(III) sulfide
Answer: The incorrect pair is B) Fe₂(SO₃)₃ iron(III) sulfite. Explanation: This question involves understanding chemical nomenclature and the formulas corresponding to the names of chemical compounds, especially those involving transition metals and polyatomic ions. The key concepts include oxidation states, the naming conventions for ionic compounds, and the correct formulas for sulfites and sulfates. The […]
Kavitha wanted to buy a laptop. She saved 1/3 of the cost of the laptop in the first month. In the second month she saved $125 less than what she saved in the first month. She saved the remaining $525 in the third month. How much did the laptop ost? enjamin bought tokens at a funfair. He used 3/8 of them at the ring-toss booth and 5 of the remaining tokens at the darts booth. He then bought another 35 tokens and d 10 tokens more than what he had at first. How many tokens did Benjamin have irst? e number of fiction books at a library was 3/4 of the total number of books. After fiction books were donated to the library, the number of fiction books became 5/6 e total number of books. How many books were there at the library at first?
Let’s solve each problem step-by-step. Q1: Kavitha’s Laptop Cost Answer: The laptop costs $2,100. Explanation: Kavitha saved 1/3 of the laptop’s cost in the first month, then $125 less in the second month, and the remaining $525 in the third month. Let the total cost be \( x \). Steps: First month: \(\frac{1}{3}x\) Second month: […]
Which division expression is shown in the model?
Answer: The division expression shown in the model is $3 \div \frac{1}{2}$. Explanation: The model displays 8 shaded squares, each representing $\frac{1}{4}$ of a whole, totaling $2$ (since $8 \times \frac{1}{4} = 2$). The question asks which division expression is shown, and among the options, the one that matches the visual is $3 \div \frac{1}{2}$ […]
Identify the elements correctly shown by decreasing radii size. N3to N S->S2- N>N3- Cu2+>Cu+ K+>K
The image appears to be a multiple-choice question asking to identify the correct element relationships based on decreasing radii size, involving concepts of atomic radii and periodic table trends. Answer: The correct choice is N3 -> N. Explanation: This question involves understanding periodic trends, specifically how atomic radii change across periods and down groups in […]
20.- The circle graph gives the distribution of salad dressing chosen by customers at a restaurant. If approximately 200 customers order salad each day at the restaurant, which of the following is closest to the difference per day between the number who choose Italian dressing, and the number who chose vinaigrette dressing? a) 10 Salad Dressing b) 20 Italian c) 30 Vinaigrette d) 50 Blue Cheese French
Answer: The number of customers who chose Italian dressing is 90. Explanation: This problem involves understanding the distribution of salad dressing choices among customers, which is represented by a circle graph (pie chart). The key concepts involved are percentage calculations and proportions. The problem asks to find the difference in the number of customers choosing […]
The table shows the results of tossing a chipped number cube 80 times. Players A and B decide to play a game. If the roll is even, Player A wins. Otherwise, Player B wins. Is the game fair? Explain.
Answer: The game is fair; the correct choice is “Yes; the experimental probability of rolling an even is basically one-half.” Explanation: This problem involves understanding the probability of rolling even numbers on a six-sided die, and whether the experimental results (from 80 rolls) align with theoretical probability. The key concepts involved are probability theory, experimental […]
A radio station is giving away tickets to a play. They plan to give away tickets to seats that cost $10 or $20. They plan to give away at least 20 tickets, and the total cost of all the tickets can be no more than $300. Make a graph showing how many tickets of each kind can be given away.
Answer: The maximum number of tickets of each kind that can be given away without exceeding $300 is 10 tickets of each kind. Explanation: This problem involves setting up and solving a system of inequalities based on the given constraints: the total cost and the minimum number of tickets of each type. The key concepts […]
