Answer:
The first option; You must work about 62 hours.
Step-by-step explanation:
The total percent that you pay in taxes is 24.9%.
That means that you keep 75.1% of the money that you earn. We can write the following equation to determine the number of hours, h, that it will take to earn 493.68.
0.751(10.65)h = 493.68
Just divide by 0.751 and 10.65 and you will get the number of hours needed.

Answer: D. 216a^3
Have a great day.
Let
x---------> the length side of rectangle
y---------> the width side of rectangle
we know that
x=2y-----> equation 1
area=x*y-------> 28800=x*y------> equation 2
substitute 1 in 2
28800=[2y]*y-----> 28800=2y²-------> y²=14400------> y=120 m
x=2*y----> x=2*120------> x=240 m
the answer is
the length side of rectangle is 240 m
the width side of rectangle is 120 m
Answer:
C)78.5
Step-by-step explanation:
∠BOZ = X
∠WOB = 7X - 4
X + 7X -4 = 180 {STRAIGHT LINE }
8X = 180 + 4
8X = 184
X = 184/8
X = 23
∠WOB = 7X - 4 = 7*23 - 4 = 161 - 4 = 157
OA bisects ∠WOB. So, ∠WOA =∠AOB
∠AOB = 1/2 of ∠WOB = 157/2 = 78.5
Answer: B. (1/200 = x/19.5)
EXPLANATION
Space shuttle Atlantis model scale 1:200
Length of Atlantis on model = 19.5
The actual length of Atlantis = x
Find x
Scale = 1:200; in decimal = 1/200
When length on model = 1
Actual length = 200
When actual length = x
Length on model = 19.5
Scale = x:19.5 ; in decimal = x/19.5
Equating both scales,
1/200 = x/19.5 (Option B)
