Answer:
-0.38%
Step-by-step explanation:
Divide 31 by 50. 31 / 50 = 0.62.
1 - 0.62 = 0.38
Since it is a decrease in change the percent change is negative.
-0.38%
Answer:
2323
Step-by-step explanation:
According to the questions above, the report from the traffic jam says the traffics jam stretches for 5.5 miles
As Connor assumes that each car is about 12.5 long
The next step is to convert 5.5 miles into feet.
Since 1 mile = 5280
To convert 5.5 miles, 5.5 x 5280 = 29040 feet
To find the numbers of cars struck in traffic, we will have to divide 29040 by 12.5
29040/12.5 = 2323.3 ≅ 2323
Answer:
Step-by-step explanation:
okay is there a graph for it? or is it just like that?
Answer:1
1. 
2. ∠ABC = 120°, ∠BCD = 90°, ∠CDA = 60°, ∠DAB = 90°
Step-by-step explanation:
It's important to note here that the measure of all interior angles in a quadrilateral will add up to 360°
We know this using the formula
, a 4 sided figures angles will add up to
This means that all of the angles (4x, 3x, 2x, 3x) will add up to 360.
Combine like terms:
Divide both sides by 12:
We know now substitute x for 30 in for all of the side lengths.
∠ABC = 4x = 
°
∠BCD = 3x = 
°
∠CDA = 2x = 
°
∠DAB = 3x = °
Hope this helped!
