Answer:
The correct answer is t < 60.
Step-by-step explanation:
Lauren wants to keep her cell phone bill below $60 per month.
Lauren's current cellphone plan charges her a fixed price of $30 and per text price for one text is $0.50.
Let Lauren sends t texts in a complete month.
Total money spent on texts in a month is given by $ (0.50 × t)
Therefore Lauren's total spent in a month is given by $ (30 + (0.50 × t)).
But this amount should be under $60 as per as the given problem.
∴ 30 + (0.50 × t) < 60
⇒ (0.50 × t) < 30
⇒ t <
⇒ t < 60.
So in order to keep her phone monthly bill under $60, Lauren should keep her number of texts below 60.
Answer:
x ≈ 46°
Step-by-step explanation:
Since the triangle is right use the sine ratio to solve for x
sinx = =
, hence
x = (
) ≈ 46°
Answer:
Part A: 25% of 50 = 12.5
Part B: 25% of 60 = 15
Part C: 50% of 60 = 30
Part D: 75% of 60 = 45
Part E: 75% of 30 = 22.5
Part F: 100% of 22.5 = 22.5
Part G: 10% of 22.5 = 2.25
Part H: 50% of 45.7 = 22.85
Step-by-step explanation:
To find - Do you know the answer to
Part A: 25% of 50 =
Part B: 25% of 60 =
Part C: 50% of 60 =
Part D: 75% of 60 =
Part E: 75% of 30 =
Part F: 100% of 22.5 =
Part G: 10% of 22.5 =
Part H: 50% of 45.7 =
Proof -
Part A :
25% of 50 = =
= 12.5
⇒25% of 50 = 12.5
Part B :
25% of 60 = =
= 15
⇒25% of 60 = 15
Part C :
50% of 60 = =
= 30
⇒50% of 60 = 30
Part D :
75% of 60 = =
= 45
⇒75% of 60 = 45
Part E :
75% of 30 = =
= 22.5
⇒75% of 30 = 22.5
Part F :
100% of 22.5 = = 22.5
⇒ 100% of 22.5 = 22.5
Part G :
10% of 22.5 = = 2.25
⇒ 10% of 22.5 = 2.25
Part H :
50% of 45.7 = =
= 22.85
⇒50% of 45.7 = 22.85
