Answer:
96
Step-by-step explanation:
Because the perimeter of a rectangle is 2 * (length) + 2 * (breadth),
P = 2 * 28 + 2 * 20
P = 56 + 40 = 96
Answer:
The number is 7.
Step-by-step explanation:
First, use the inverse operation of multiplication, which is division. Then, divide 42 by 6, and you get 7. To prove this, multiply 7 by 6, and you get 42.

Each Student would get 3/16 of the pizza. This is because when you have a fraction, it's the same as saying dividing. So 3/4 is equal to 3÷4. Once you have 3÷4= 0.75. then you can divide that by 4, getting 0.1875. Although this is still an exact calculation, most people would automatically understand better in the fraction form of 3/16, so it is better to switch it back. This can be done either on your own or with a calculator, most scientific calculators have the ability anyways so it shouldn't be a big deal. In the end, if the pizza has 16 slices, each student gets 3, if it has 8, then each student gets 1 1/2.
Angles 6 and 3 are supplementary. If angle 6 is 140, then angle 3 is 40. Because those lines are parallel and cut by a transversal, then angles 3 and 1 are corresponding and congruent. That means that angle 1 measures 40° also. Choice D.
