Answer:
30 small pretzels were sold that night.
Step-by-step explanation:
x = small pretzels
y = large pretzels
x + y = 50
2x + 4.5y = 150
x + y - y = 50 - y
x = 50 - y
2(50 - y) + 4.5y = 150
100 - 2y + 4.5y = 150
2.5y = 50
------- -----
2.5 2.5
y = 20
x + 20 = 50
x + 20 - 20 = 50 - 20
x = 30
Answer:
w = 206
Step-by-step explanation:
This is because the sum of the interior angle and the side of a triangle have to equal to 360.
Therefore 102+52=154
Then you would subtract 154 from 360
You are then left with w=206

Answer:
Step-by-step explanation:
The significant figures of a number that carry meaningful contribution to its measurement resolution
Answer:
(a) The time to complete 1 cycle and return is 16/3
(b) The minimum height is 30 inches and the maximum is 54 inches
Step-by-step explanation:
Given
Solving (a): Time to complete 1 cycle and return
This implies that we calculate the period. This is calculated using:
Where:
So, we have:
Solving (b): The maximum and the minimum height
To do this, we have:
Which means:
So, the minimum is:
And the maximum is:
Recall that the height is:
So, the maximum and the minimum of are:
and
