NWEA MAP Test: Math Section Practice

The correct answers are (B) 72 hours and (C) 3 days. You already have the time taken for one mile, so the snail would take double the length of time for two miles.

There are 24 hours in a day so in 3 days, you need to multiply 24 by 3. Alternatively, you could add three 24s. 24 × 3 = 72 hours. 24 + 24 + 24 = 72 hours. Therefore, the correct answers are 3 days and 72 hours.

The correct answers are (A) and (F). An equilateral triangle has three equal sides and three equal angles. Every angle is 60 degrees. You only need to recognize one of these properties to know it is equilateral. Triangle (A) has two equal angles of 60 degrees.

Therefore, to calculate the third angle, subtract the sum of the other two angles from 180 degrees. 60 + 60 = 120. 180 – 120 = 60 degrees.

Therefore, the third angle is also 60 degrees, and thus the triangle is equilateral. Triangle (F) has three equal sides, and therefore it is equilateral. The other four triangles do not contain either of these properties and therefore are not equilateral.

Triangle (B) has a right-angle and is, therefore, a right triangle. Triangle (C) has two equal sides only and is, therefore, an isosceles triangle. Triangle (D) has no equal sides and is, therefore, a scalene triangle. Triangle (E) has a right-angle symbol and is, therefore, a right triangle.

The correct answer is (B). There are a few ways to approach this multiplication equation. One method is to first simplify the left-hand side by multiplying six by 25p. As 6 x 25 = 150, then 6 x 25p = 150p. If you are not confident with the multiplication table for 25, then decompose 25 into 20 and 5.

Then, multiply each part by six and then add. 6 x 20 = 120 6 x 5 = 30 Total = 150 Now, rewrite the equation: 150p = 450 // divide both sides by 10* 15p = 45 // divide both sides by three* 5p = 15 // divide both sides by five* p = 3 *If you are able, divide the equation by 150 immediately.

If not, divide them into batches, as above. Therefore, the correct answer is (B). An alternative approach is to first divide both sides of the equation by six, or by 25, and then proceed.

The correct answer is (C). There are 1,000 grams in a kilogram. To convert from grams to kilograms, you must divide by 1,000. 6,300 ÷ 1,000 = 6.3

Dividing by 1,000 is the same as dividing by 10 three times: 6,300 ÷ 10 = 630 630 ÷ 10 = 63 63 ÷ 10 = 6.3 In the last division, you need to put in a decimal point as 63 does not end in zero so dividing by 10 makes it a decimal number. Therefore, the correct answer is (C).

The correct answer is (C). To solve this question, you need to remember something called the triangular inequality. The triangular inequality states that in a triangle, any side of the triangle must be smaller than the sum of the other sides, and bigger than their difference.

Denote the missing length by x. Then, by the triangle inequality, you know that: "8 – 5 = 3 < x < 13 = 8 + 5" So, the missing length is between three and 13. Only one answer choice fulfills the criteria.

The correct answer is (D). There are two ways to solve this question. You can find the discount of each item separately and then add the price after the discount, or you can add the prices of the items together and then calculate the discount from the total price.

Examine the second option and add the prices of both items and afterward, calculate the discount. To find the value of a certain percent of a number, multiply this percent (20% in this case) by that number, then divide the result you get by 100.

In this case, the two items cost 40 and 30 dollars, meaning that the total price is 70 dollars: (70×20) ÷ 100 = (70 × 10 × 2) ÷ 100 = (700 × 2) ÷ 100 = 1400 ÷ 100 = 14 Now that you know the value of the discount percent ($14) of the total price ($70), reduce it from the original price tag and get the current cost during the sale: 70 - 14 = 56 ($). →Therefore, (D) is the correct answer.

Notice that answer (A) is $14$, which is the value of the discount, not the total cost of the items after the discount, which is what the question is asking. Alternatively, you can reduce the percentage of discount (20%) from 100% and find the value of the discounted percent of the price: 100% - 20% = 80% and then 80 × 70 ÷ 100 = 56.

As mentioned, you can separate the two items (shirt and jeans) and calculate each percent separately and then sum them after the discount. This will be one extra step since there will be two percent calculations to perform instead of only one, but on the other hand, each of them could be simpler.
