To find the area of a trapezoid, it’s 1/2(base 1 + base 2) x height.
so in this case, base 1 is 16 (add 12+2+2) (the top one) and base 2 is 12 (the bottom one) and the height is 9.
you input all the values in the formula and you get 126in.
hope this helped:)
Answer:
(a) $60
(b) $180
Step-by-step explanation:
Let the price of 1 table lamp be t.
Then the price of a fan is 3t.
2(3t) + 3t = 540
6t + 3t = 540
9t = 540
t = 60
A table lamp costs $60.
3($60) = $180
A fan costs $180.
For this, the number we are looking for is x.
use this formula... 17 - 3 = 2x
therefore, 14 is your doubled number.
14 divided by two is 7.
your mystery number is 7
Answer:
15
Step-by-step explanation:
since c is the centroid, therefore PX=XQ=1/2 x PQ
∴ PX=15
