Answer:
40 weeks
Step-by-step explanation:
You can use the fact that there are 52 weeks in a year. If she attends school for 3/4 the year, find out what 3/4 of 52 is, and then add 1:
52/1 * 3/4 = 156/4 = 39 This is 3/4 year
39 + 1 = 40
Answer:
21.4 units
Step-by-step explanation:
Greater angle: 180 - 80 = 100
diagonal² = 14² + 14² - 2(14)(14)cos(100)
diagonal² = 460.0700856454
diagonal = 21.4492444073
(7x - 4x) + (5 - 16)
3x - 11
We will calculate it like this, We will make a right angle triangle by adding one new point called O for example, and O is located right under the point C, and on the right side of point D, so the coordinated for this point are O (8, -2). From there, length CD is calculated using the Pythagorean theorem, because we know that the CO = 4 and DO = 4, so:
CD^2 = CO^2 + DO^2
CD^2 = 4^2 + 4^2
DC^2 = 16 + 16
DC^2 = 32
DC = square root of 32 = square root of 16 * square root of 2
DC = 4 * square root of 2
The correct answer is B. 4*square root of 2.
