Answer:
121 sweets
Step-by-step explanation:
David is the first 4 in the ratio 4:3:4. We know that David gets 44 sweets. We also know that Paul gets 44 sweets because he is the other 4 in the ratio. To find out how many sweets 3 is equal to, you need to find the unit rate. To do this, you can divide 44 by 4 to know how much 1 equals. When you divide 44/4, you get 11. This means that 1 is 11. To find out what three is, you can multiply 11 by 3 to get 33. The question asks how many sweets are there altogether, so you must add 44+33+44. This equals 121.

Answer:
1.03
Step-by-step explanation:
1.029 is closer to 1.03 than 1.02, so round it to 1.03.
This is the area of a trapezoid and the formula for that is:
.5(h)(b1 + b2) where h is height and b1 and b2 are the base length or the length of the parallel sides. therefore, our area is:
.5(16)(6+12)
8(18)
144
if you're wondering why the area formula works, construct another trapezoid but this time upside-down. now flip it along it's height axis so you can align one of the side lengths of the 2 trapezoids and you have a parallelogram.
the base of this parallelogram is b1+b2 of the original trapezoid and the height still remains h so the area of this parallelogram is (h)(b1 + b2). however, we want to find the area of the trapezoid but we find that the parallelogram is twice the area of our trapezoid so the area of the trapezoid is half the area of the parallelogram. so area = .5(h)(b1 + b2).
