Do not ask if your score is "bad," or tell anyone that their score is "bad." Since a = (2/3)b, the perimeter of the triangle is b + b + (2/3)b = (8/3)b.Welcome to /r/SAT! This community aims to promote discussion of the SAT and of various methods to prepare for the exam. If the ratio of a to b is 2 to 3, what is the value of b? Show/Hide Answer Key The perimeter of the isosceles triangle above is 24. SAT Math Practice Online Test Question No 9: If 4 + √b = 7.2, what is the value of 4 – √b? Show/Hide Answer Key SAT Math Practice Online Test Question No 8: ![]() You can substitute 10,200 for 96,878 × x 2 because they are equal. SAT Math Practice Online Test Question No 7: What is the value of > – >? Show/Hide Answer Key SAT Math Practice Online Test Question No 6:įor every integer m greater than 1, let ?m? be defined as the sum of the integers from 1 to m, inclusive. If she made 52% of her shots altogether, then If she took a shots in her first game and made 50% of them, then she made. If she took a shots in the first game and b shots in the second game, what is the value of a/b? Show/Hide Answer Key In the two games, she made 52% of her shots altogether. In one basketball game, Tamara made 50% of her shots, and in the next game, she made 60% of her shots. SAT Math Practice Online Test Question No 5: This simplifies the complex expression to just 2m, which equals 6 when m = 3. If you happen to be an algebra jock, you might notice that you can simplify the original expression by multiplying the numerator and denominator by the common denominator m 2 – 1, which is equivalent to (m – 1)(m + 1). The quickest way to simplify this expression is to multiply both the numerator and the denominator by the common denominator, 8. Simply substituting m = 3 in the equation gives /(1/8). If m = 3, what is the value of ? Show/Hide Answer Key ![]() SAT Math Practice Online Test Question No 4: If 4/9 of c 2 is 24, what is 5/9 of c 2? Show/Hide Answer Key SAT Math Practice Online Test Question No 3: Check out the following diagram for clarification. If you can find the distance from point B to point H using the two-dimensional distance formula d = √x 2 + √y 2 which is based on the Pythagorean Theorem, then you can use right triangle BHE to find the length of BE. It would be great if you happened to know the three-dimensional version of the distance formula: d = √x 2 + √y 2 + √z 2, but just in case you don’t, you can solve this another way. ![]() SAT Math Practice Online Test Question No 2:ĭetermine the length of segment BE. Angle 4 and angle 3 are vertical angles and, therefore, equal, so the measure of angle 4 is 80 degrees. Now you know the measures of two of the angles in the triangle ABE, so you know that angle AEB = 180° – 50° – 50° = 80°. BD is a transversal, meaning that angle 2 is equal to angle 6 because they’re alternate interior angles. Then, because you know that AB is parallel to CD. You can immediately see that angle 6 must have a measure of 180° – 130° = 50°. Remember that the drawing isn’t to scale. What is the measure of angle 4? Show/Hide Answer Keyįor problems like this one, marking up your test booklet is always a great idea. If AB || CD, the measure of angle 7 is 130.
