Step-by-step explanation:
it clearly consists of 2 rectangles and 1 triangle (as you tried correctly to point out by drawing the separating lines).
we only need to calculate all 3 areas and add them up for the total.
the area of a rectangle is
length × width
so, in our 2 cases we have
6 × 2 = 12 km²
5 × (3 + 2 + 3) = 5×8 = 40 km²
the area of a triangle is
baseline × height / 2
in case of a right-angled triangle the 2 sides enclosing the 90° angle can be used as baseline and height.
so, in our case
6 × (5 + 2 + (3 + 2 + 3 - 2)) / 2 = 6×(7 + 6)/2 = 3×13 = 39 km²
in total, the whole area is
12 + 40 + 39 = 91 km²
What are the following rates?
Answer:
odd: 4/7
not 3: 6/7
4 or 5: 2/7
spinner spun 2: there both 1/7 i think im
only in 7th grade ;-;
Step-by-step explanation: well there are 7 spaces so the probabilty
of it landing on an odd space on the wheel is how many odd numbers there are over 7 . and there is only 1 three so the chance that it will not land on 3 is 6/7. there is a 2/7 chance it will land on 4 or 5. and im not to sure abt the last one but like i said im only in the 7th grade i am taking p classes tho so the rest should be right. :D
Answer:
The inverse of f(x) is 
Step-by-step explanation:
To find the inverse of the function 
, perform the following steps:
1) do 
2) Solve the equation for the variable x.
3) exchange the variable x with the variable y
----> 
4) Change the variable y by 
Finally the inverse function is:
