The area of a trapezoid is half its height multiplied by the sum of the lengths of its two bases.
6,550=1/2b(115+85)
<span>115+85= 200
1/2*200= 100
6,550/100=65.5
h=</span><span>65.5
</span>
The height is 65.5 cm
Answer:
The total surface are is 252 sq. units.
Step-by-step explanation:
The right triangular sides have legs 8 units and 6 units and hypotenuse 10 units.
So, their area will be
sq. units.
Now, the length of the prism is 8.5 units.
So, the area along the length will be = (8.5 × 6 + 8.5 × 8 + 8.5 × 10) = 204 sq. units.
Therefore, the total surface area is (48 + 204) = 252 sq. units. (Answer)
According to the question statement, the total sum of students is 221, which includes the students that ride on bus and the students that ride in a van.
The students that ride in a van are five, the students that ride on bus are 6 times s which is the product of the number of buses and the number of students that are on each bus.
Write all this information into an equation, this way:

Now, solve the equation for s to find the number of students that are on each bus.

There are 36 students on each bus.
Answer:
m=11
Step-by-step explanation:
-6m-6=72
-6 on both sides to cancel it out
72 becomes 66
-6m=66
divide by -6 on both sides to cancel out
66÷6=11
m= 11
