Answer: D) 99 Points
Step-by-step explanation: Theresa earned scores of 88 points, 84 points, 88 points, and 91 points on four tests
Therefore the totals points are 351
351 is her total score for 4 tests, if she gets an average score of 90 on her fifth test then all we have to do is:
5 x 90 = 450 (The 5 being her fifth test)
450-351 = 99
Option D
Answer:
Step-by-step explanation:
By applying tangent rule in the given right triangle AOB,
tan(30°) = 
By applying tangent rule in the given right triangle BOC,
tan(60°) = 
OC = BO(√3)
OA + OC = AC
2√3(BO) = 60
BO = 10√3
OC = BO(√3)
OC = (10√3)(√3)
OC = 30
By applying tangent rule in right triangle DOC,
tan(60°) = 
OD = OC(√3)
OD = 30√3
Since, BD = BO + OD
BD = 10√3 + 30√3
BD = 40√3
≈ 69.3
Answer:
f(x)= 7.5x + 3
Step-by-step explanation:
you have 3 dollars just there, and you get 7.50 per car wash, so that is the x
How Much did the dinner cost? 12 divided by 3 = 4 So each person would pay 4$ for the tip.
One worker earned $6,450. I’m assuming you put the comma in the wrong area and the total of money they earned together was $103,200. The way I got $6,450 per worker was by dividing $103,200 by the 16 workers. And the outcome of that was $6,450.
