Your answers are correct! Here's how you can solve each question:

1. To find out how much money Liam must raise, you need to calculate 40% of $290.00. To do this, multiply $290.00 by 40% (or 0.40). The calculation is: $290.00 * 0.40 = $116.00. So, Liam must raise $116.00 himself. The correct answer is C. $116.00.

2. To solve the proportion, you need to set up the cross-products and solve for the variable h. The cross-products are 29 * h = 58 * 10. Simplifying the equation, you get: 29h = 580. To isolate h, divide both sides of the equation by 29. The calculation is: h = 580 / 29 = 20. So, h is equal to 20. The correct answer is B. 20.

3. To find the percent, you need to set up a proportion. The equation to set up is: x/100 = 77/192. To solve for x, cross-multiply and then divide. The calculation is: 192x = 77 * 100. Simplifying further, you get: 192x = 7700. To isolate x, divide both sides of the equation by 192. The calculation is: x = 7700 / 192 ≈ 40.1. So, 77 is approximately 40.1% of 192. The correct answer is B. x/100 = 77/192; 40.1%.

4. To find the number when 26 is 65% of it, you need to set up a proportion. The equation to set up is: x/26 = 65/100. To solve for x, cross-multiply and then divide. The calculation is: 100x = 26 * 65. Simplifying further, you get: 100x = 1690. To isolate x, divide both sides of the equation by 100. The calculation is: x = 1690 / 100 = 16.9. So, 26 is equivalent to 65% of approximately 16.9. The correct answer is B. x/26 = 65/100; 26.
