Answer:
Step-by-step explanation:
A trapezoid area is a rectangle area plus one or two trianagles areas on each end
Area of a trapezoid =( base 1 x height) + ((1/2)(base 2 - base 1) x height)
solve for height
factor out the height
Area = height [ base 1 + 1/2(base 2 - base 1)]
divide both sides by [ base 1 + 1/2(base 2 - base 1)]
Area / [(base 1 + 1/2(base 2 - base 1)] = height
plug and chug
68 / ( 7 + (1/2)(27 - 7) = height
height = 68 / (7 + (1/2)(20))
= 68 / 17
= 4 ft <-------------- FINAL ANSWER

Explanation:
The problem statement tells you the meaning of t. It is minutes after Riko leaves. 0 ≤ t < 52.5 is the answer to the question regarding the interval Riko is behind Yuto. It means Riko is behind Yuto for 52.5 minutes after she leaves their house.
t will not be negative because time moves forward. Here, we're only counting time <em>after Riko leaves the house</em>. A negative value for t would refer to a time before Riko leaves the house, which is irrelevant in this problem.*
_____
* One might argue that Riko is behind Yuto for all values of time <em>after Yuto leaves the house</em>, which would be for -21 < t < 52.5. The concept of "behind Yuto" has no meaning except in that interval.
1. Inches.
2. Car sizes vary from 15 ft, to 20 ft, and even to 13 ft. It all depends on the size the manufacturer wanted it to be. But if you are asking what is the best way to measure a car, it would be yards. Or meters, but a yard is slightly bigger.
3. 7 1/2 hours.
4. A parallelogram , a quadrilateral, a square, and a rectangle.
5. 180°.
Hope this helped!
Answer:
C
Step-by-step explanation:
Triangle A is a reflection across the x-axis. All the y coordinates are negated.
Triangle B is a rotation 180° about the origin. All coordinates are negated.
Triangle C is a translation to the left by 6 units. 6 is subtracted from each x-coordinate.
Triangle D is a reflection across the y-axis. All the x-coordinates are negated.

<em>Comment on presentation</em>
Your question would be much easier to read if you would simply use minus signs (hyphens) and conventional ordered-pair presentation: (1, -1), (1, -4), (3, -1), for example, for triangle A.
Answer:
CU = 12
Step-by-step explanation:
Clearly from the diagram of the triangle we can say that,
AD, BE and CF are the medians of the triangle ABC , since they are bisecting the sides of the triangle equally.
Also , U is the intersection point of the these mediands of the triangle whic is known as centroid of the triangle.
Now, from the property of the centroid , centroid divides the median in the ratio of 2 :1 from the point C .
Thus CU will be times of CF (median) .
Given is Cf equals 18 ,
Thus , CU = ×18 = 12.
So, CU equals 12 .
