Answers for 1-126
Step-by-step explanation:
a. x + 8 = 21
-8 -8
x = 13
b. x - 32 = 55
+32. +32
x = 87
c. 3x = 54
÷3. ÷3
x = 18
d. x/5 = 10
×5. ×5
x = 50
Answer for 1-124
1/5 = 2/10 , so 2 of the 10 colors are blue and 3 of the 10 colors are green.
The probability is 5/10 = 1/2
this is all I could do. sorry
Answer:
Circle
Step-by-step explanation:
because a hyper bole is (y-k) 2b2 -(x-h) 2a2=1
ellipse is = (x-h) 2a2 + (y-k) 2b2 = 1
parabola is y= a (x-h) 2+ k
that's why circle is the answer
Answer: The the speed of elevators is 22.55.
Explanation:
It is given that observation deck of the willis tower in Chicago Illinois is 1353 feet above the ground elevators lift visitors to that level in 60 seconds.
The speed is the change in distance with respect to time.

From the given information the total distance is 1353 and the total time is 60 seconds. So by the above formula we get,


Therefore, the speed of elevators is 22.55.
