Answer:
126 cm^2
Step-by-step explanation:
Let's name the point where the two triangles meet on the horizontal line point Z. Then the area of the left triangle is ...
A(left) = (1/2)(XZ)(AX)
and the are of the right triangle is ...
A(right) = (1/2)(ZY)(YC)
Now, we know that AX = YC = (1/2)AD, so the sum of the two triangle areas is ...
A(triangle total) = A(left) +A(right)
= (1/2)(AX)(XZ +ZY)
Since XZ +ZY = AB, we have the total triangle area equal to ...
A(triangle total) = (1/2)((1/2)AD)(AB) = (1/4)(AD)(AB)
Now (AD)(AB) = 168 cm^2, so the <em>unshaded</em> area is ...
A(unshaded) = A(rectangle) -A(triangle total)
= 168 cm^2 -(1/4)(168 cm^2)
= 126 cm^2
The unshaded area in the figure is 126 cm^2.
Answer:
36
Step-by-step explanation:
6^ +6-1-5=36
Answer:
The difference between the longest and shortest gliders is 6.
More gliders flew shorter than 35 feet because there is 12 dots behind 35 and only 8 in front of it.
Answer:
0.3048 or 1/3.281
Step-by-step explanation:
To create a conversion factor the first thing is to find the equivalence between these two units meters and feet.
We have that 1 ft is equivalent to 0.3048 meters, therefore and as long as you want to go from meters to feet, the following operation must be performed:
x feet * 0.3048 meters / 1 foot = x * 0.3048 meters.
It could also be x / 3.281 meters
That is, let x be any value of length in feet, it must already be multiplied by 0.3048 or divided by 3.281.
P(person has less than a high school education) = 0.12. This is directly from the table.
P(person has at least a bachelors degree: Hard to say for certain, because some of the data in your illustration was cut off.
