Since they are right triangles use Pythagorean Theorem.
a^2 + b^2 = c^2 where c is the hypotenuse.
a. 12^2 + b^2 = 13^2
144 + b^2 = 169
subtract 144 from both sides
b^2 = 25
take the square root of both sides
t = 5 This is also know as a Pythagorean Triple 5-12-13
b. a^2 + 9^2 = 12^2
a^2 + 81 = 144
subtract 81 from both sides
a^2 = 63
take the square root of both sides
a = √63
a = √(9 * 7)
a = 3√7
c. 6^2 + 9^2 = c^2
36 + 81 = c^2
117 = c^2
take the square root of each side
c = √117
c = √(9*13)
x = 3√13
If you put it into the slope intercept from (x1,y1) and (x2,y2)
then subtract 3-8 and 2-5 you should get 5\3 as your answer.
Answer: she bought 5 bouquets
explanation: add the yellow and white daisies together to get 18 then do
90 ÷18=5
Answer:
Step-by-step explanation:
Im not full sure what the answer is but I do know that A statistical question is one that can be answered by collecting data and where there will be variability in that data. This is different from a question that anticipates a deterministic answer. For example, "How many minutes do 6th grade students typically spend on homework each week?" is a statistical question.
I think that a one of the answers may be number 3 but im not 100%
Just subtract 8749 feet from 14497 feet.
14497 feet
- 8749 feet
----------------
? feet
