How can you save money? How should a building be designed? How do you train for a competition? In the real world, math problems involve many disciplines, are complicated, and don’t have an answer key. The Center for Model Schools (formerly ICLE)Ĭustomer Service & Technical Support Portal Into Algebra 1, Geometry, Algebra 2, 8-12 The testĬontained a total of 80 questions.Science & Engineering Leveled Readers, K-5 Mario answered 30% of the questions correctly. A recipe calls for 2 1/2 cups and I want to make 1 1/2 recipes. The ordered pair (100, 212) is also an ordered pair of this functionīecause 100☌ is equivalent to 212° F, the boiling point of water.Ģ. The ordered pair (0, 32) is an ordered pair of thisįunction because 0☌ is equivalent to 32☏, the freezing point of water. Fahrenheit temperature F is a linear function of Celsius Put the value of x = 2y/ 3 and z = 8y/ 5 in (i).ġ. The ratio of the second to the third is 5/ 8. The ratio of the first to the second is 2/ 3. The ratio of the first to the second is 2/ 3, and the ratio of the second to the third is 5/ 8. The values of A and B must be, respectively: The fraction (5x-11)/ (2x 2 + x - 6) was obtained by adding the two fractions A/ (x + 2) and B/ (2x - 3). If (0.2) x = 2 and log 2 = 0.3010, then the value of x to the nearest tenth is: So we can clearly see that his new time compared with the old time was: twice as much. So, times taken to covered a distance of 50 miles on his first trip = 50/x hr.Īnd times taken to covered a distance of 300 miles on his later trip = 300/3x hr. (a) three times as much, (b) twice as much, (c) the same, (d) half as much, (e) a third as much Solution: Trip he traveled 300 miles while going three times as fast.
Jones covered a distance of 50 miles on his first trip. Therefore, he invested the remaining amount $ 2500 at 6.4 % in order to get $ 500 income every year. Rate = r ,ġ60/2500 = 2500r/2500 Ĭhange it to a percent by moving the decimal to the right two places We know that, Interest = Principal × Rate × Time Remaining income amount in order to have a yearly income of $ 500 Income from $ 3500 at 4 % in one year = $ 3500 of 4 %. Income from $ 4000 at 5 % in one year = $ 4000 of 5 %. In order to have a yearly income of $ 500, he must invest the The distance of the light travels in 100 years is:ĥ. The distance light travels in 100 years is: The distance light travels in one year is approximately 5,870,000,000,000 miles. Therefore, total cost price of the two pipes = $1.00 + $1.50Īnswer: (d) 4. Let’s try to find the cost price of the second pipe Let’s try to find the cost price of the first pipe (a) broke even, (b) lost 4 cents, (c) gained 4 cents, (d) lost 10 cents, (e) gained 10 cents Solution: Profit one was 20% and his loss on the other was 20%. Put the value of x = 2 in the above expression we get,ģ.
So in this way end of every week her salary will increase by $ 145.Ģ. Similarly after completing the 2nd week she will get $ (x + 145) + $ 145.
So after completing the 1st week she will get $ (x+145).
