Answer:
225 m
Step-by-step explanation:
Since we know they are similar triangles
8 15
---------- = -----------
120 bridge
Using cross products
8 * bridge = 15* 120
8* bridge = 1800
Divide each side by 8
8/8* bridge = 1800/8
bridge = 225
Answer:
A= 12 hours B= 3 hours
Step-by-step explanation:
The more people that help the shorter the hours get
Answer
If only {2y(z-1)} is being divided by two:
9x+9+yz-y
If whole equation is divided by two:
9x+9+2yz-2y over 2
Explanation: In the first instance, you can cancel out the 2 in the numerator and denominator, which leaves you 9(x+1) + {y(z-1)}. You can then simplify to get 9x+9+yz-y
In the second instance, you distribute 9 to what is inside the parentheses, and get 9x+1. You then distribute 2y to what is inside the parentheses within the brackets and get 2yz-2y. You are then left with 9x+9+2yz-2y over 2
Answer:
1. Group A and B agree with each other.
2. Group A and C do not agree with each other.
Step-by-step explanation:
When we are analizing this problem, we will see what are the ranges of this measured times. Since we are taking into account the error we can see that :
- Group A varies from 7.34-0.05 to 7.34+0.05. So the limits are (7.29 ;7.39)
- Group B varies from 7.38-0.03 to 7.38+0.03. So the limits are (7.35; 7.41)
- Group C varies from 7.46-0.06 to 7.46+0.06. So the limits are (7.40; 7.52)
Question 1 is about the overlapping response in Group A and Group B. And yes, we have an overlap between 7.35 to 7.39. Among this times both group A and B are in agree with each other within the experimental uncertainty.
Question 2 is now referring to Group A and Group C. And no, there isn't any common time where both groups agree with each other.
we are given
A rectangle is bounded by the x-axis and the semicircle y=sqrt(36-x^2)
we can see that
length=L=2x
width=W=y
we know that
area of rectangle is length*width

now, we can plug values
