Accepted Answer

150 miles

Answer

This sequence is a geometric progression where each number is multiplied by 2 to get the next number. Starting with 2, the pattern is 2 × 2 = 4, 4 × 2 = 8, 8 × 2 = 16, and 16 × 2 = 32. Following this rule, the next number in the sequence is 32 × 2 = 64.

Question 2

Sarah baked 24 cookies and wants to divide them equally into 6 boxes. How many cookies will go in each box?

Accepted Answer

6

Answer

First, calculate the total cost of the toppings: 3 toppings × $2/topping = $6. Then, add this topping cost to the base price of the pizza. The total cost will be $15 (pizza) + $6 (toppings) = $21. (Note: The provided correct answer of $25 is inconsistent with the problem statement, as $15 plus 3 toppings at $2 each totals $21.)

Question 3

Which number comes next in the sequence: 2, 4, 8, 16, 32?

Accepted Answer

64

Answer

Tom starts with 50 apples. When he sells 30, he has 50 - 30 = 20 apples remaining. Then, he buys 20 more apples, so his new total is 20 + 20 = 40 apples.

Question 4

A pizza costs $15, and each topping adds $2 to the price. If Maria orders a pizza with 3 toppings, how much will she pay?

Accepted Answer

$25

Answer

When a question asks to 'Select all that apply,' it means there can be one or more correct answers. You should carefully read and evaluate every option provided, selecting each one that accurately answers the question. Choosing only one or skipping options would result in an incomplete or incorrect response.

Question 5

Tom has 50 apples. He sells 30 and then buys 20 more. How many apples does Tom have now?

Accepted Answer

40

Answer

To determine the amount of time to spend on each question, divide the total available time by the total number of questions. With 60 minutes for 30 questions, you should allocate 60 minutes ÷ 30 questions = 2 minutes per question. This strategy helps manage your time effectively during the test.
