Answer:
multiple choice or what?
Step-by-step explanation:
could use 2l+2w, that would be perimiter. L=12, so 12+12+2w.
Answer:
Step-by-step explanation:
The bases of a triangular prism are equilateral triangles, since they have equal sides: 5, 5, and 5
yes, since if all lateral faces are rectangles, rectangles are formed from 4 perpendicular segments, thus, if all edges of the lateral faces are perpendicular, then they are rectangles
Answer:
9
Step-by-step explanation:
5(n-2)=35
5n-10=35
5n=35+10
5n=45
n=45/5
n=9

Answer:
πr²
Step-by-step explanation:
The surface area of a circle is πr²
Pie is 22/7 or 3.14
While the radius of a circle is any line from the centre of a circle to any part of the circumference of the circle. A diameter is any line that cuts the circle into two equal halves, cutting the circle from the centre.
To get the surface area of a circle, you draw a line from the centre of the circle, and then touch any part of the circumference of the circle. Then you measure the line, that's the radius.
If for instance, the radius gives 7cm, you find the Square, And then multiply it with pie.
22/7 X 7 ²
22/7 X 7 X 7
22 X 7
154cm²
Answer:
B. Configuration B has a higher probability of an aisle seat.
Step-by-step explanation:
Each configuration has the same number of seats in every row. That means we can determine the probability Dan will be assigned an aisle seat by considering only one row.
In configuration A, each row has 6 seats, of which 2 are aisle seats. The probability of being assigned an aisle seat is ...
p(aisle) = 2/6 = 1/3 . . . . configuration A
In configuration B, each row has 9 seats, of which 4 are aisle seats. The probability of being assigned an aisle seat is ...
p(aisle) = 4/9
Since 4/9 > 1/3, Dan should hope his flight uses configuration B.
