Answer:
Area of the gym floor = 100.8 square meters
Step-by-step explanation:
Area of the gym floor = Area of rectangle A + Area of rectangle B - Area of the overlap
Area of rectangle A = 105 square meters
Area of rectangle B = 8.4 square meters
Area of the overlap = 
= 
= 12.6 square meters
Area of the gym floor = 105 + 8.4 - 12.6
= 100.8 square meters
Therefore, area of the gym floor is 100.8 square meters.
Answer:
2x + 5x - 4 + 1
basic addition of terms together
( 2 + 5 ) x + ( -4 + 1 )
7x - 3
Significant figures tells us that about how may digits we can count on to be precise given the uncertainty in our calculations or data measurements.
Since, one inch = 2.54 cm.
This is equivalent as saying that 1.0000000.. inch = 2.540000... cm.
Since the inch to cm conversion doesn't add any uncertainty, so we are free to keep any and all the significant figures.
Since, being an exact number, it has an unlimited number of significant figures and thus when we convert inch to cm we multiply two exact quantities together. Therefore, it will have infinite number of significant figures.
Answer:
45°
Step-by-step explanation:
All triangles are 180°.
So, we must first add up all of the other numbers:
80° + 55° = 135°
Next, we must find how much more we need to get to 180°:
180° - 135° = 45°
So, x = 45°
And, if you want to make sure. Just add up the numbers and make sure the sum is 180.
80 + 55 + 45 = 180
I hope this helps you out ; )
Use proportions:
height/shadow
2.6/1.24 = x/38.25
Cross multiply
1.24x=99.45
x = 80.2016129
