Answer:
23
Step-by-step explanation:
tbh, i just guessed around the numbers until i got the right one xD
Perimeter of the trapezoid = a + c + 2b
58 = a + c + 2b
Average of bases = (a + c)/2
19 = (a + c)/2
a + c = 38
Substituting (a + c) into the first equation:
58 = 38 + 2b
b = 10 in
We also know that:
c = 2b + 7
c = 2(10) + 7
c = 27 in
a + 27 = 38
a = 11 in
a = 11 in; b = 10 in; c = 27 in
Answer:
(A) f=3
Step-by-step explanation:
If
We know by the rule of complementary trigonometric ratios that:
I suppose you have to find the four numbers. If
is the smallest of the four, then the next three numbers are
,
, and
. The mean is 15, so
So the four numbers are 12, 14, 16, and 18.
She can tip 90 waiters from her 90.00 tip.
5.00 / 5 waiters = 90.00 / x
5.00x = 90.00 (5)
5.00x = 450
5.00x / 5.00 = 450 / 5.00
x = 90 waiters.
or 5.00 to 5 waiters is equal to 1.00 for every waiter. thus, a $90.00 tip can tip 90 waiters for $1.00 each.
