Answer: She has to score a minimum of 92 marks to take her average to 80
Step-by-step explanation:
Let the equation be
Three months total = 76 x 3 = 228
(x + 228) / 4 = 80
x + 228 = 80 x 4
x = 320 - 228
x = 92
Since 40% does not nicely go into 100% you split the 32 baskets she made. (32/2)
This means 16 baskets is 20%. Now that 20% goes nicely into 100% you multiply 16 by 5 and 20 by 5 to get 80.
The basketball player made 80 shot attempts.
Answer:
The Triangle Sum Theorem is also called the Triangle Angle Sum Theorem or Angle Sum Theorem. It says that all the angles <em>inside</em> a triangle add up to 180°.
---------------------------------------------------------------------------------
Take a look at the picture attached. It has a "formula": ∠a+∠b+∠c=180°
Use this as it will help you a lot. You plug in the info you already know (it doesn't matter which angle is a,b,c) and solve for the missing one. :)
Ask in the comments below if you are not sure about something.
I hope that helps you! :D
Answer:
√2/4 + 1
Step-by-step explanation:
sin 45° --> √2/2
cos 60° --> 1/2
tan 45° --> 1
with these values, we write a new expression
√2/2 × 1/2 + 1
√2/2 × 1/2 = √2/4
(by doubling the denominator, you are splitting the number in half as implied by the 1/2)
your answer is √2/4 + 1
goodluck :)
