Answer:
acute: D and E
obtuse: A and F
right: B
straight: C
Step-by-step explanation:
----------------------------------------------------------
Ticket Sellers
----------------------------------------------------------
1 ticket seller = $10 x 50
1 ticket seller = $500
12 ticket sellers = $500 x 12
12 ticket sellers = $6000
----------------------------------------------------------
Cleaning person
----------------------------------------------------------
1 cleaning person = $7.50 x 50
1 cleaning person = $ 375
25 cleaning person = $375 x 25
25 cleaning person = $9375
----------------------------------------------------------
Ushers
----------------------------------------------------------
1 usher = $8.50 x 50
1 usher = $425
15 ushers = $425 x 15
15 ushers = $6375
----------------------------------------------------------
Total
----------------------------------------------------------
$6000 + $9375 + $6375 = $21750
----------------------------------------------------------
Answer: Total monthly salary per month = $21750
----------------------------------------------------------
one way is this:
if the 2 integers are x and y, then
x<√98<y
if we assume that x and y aer both positive then
square everybody
x²<98<y²
solve each
x²<98
square root both sides
x<9.89
since x must be an integer, x=9
98<y²
squaer root both side
9.89<y
since y must be an integer, y=10
√98 lies between 9 an 10
