Answer:
The answer is 0.60b + 0.30w = 150; 60 + 0.30w = 150
Step-by-step explanation:
Wei can purchase 300 balloons.
The model used for the problem is .
Step-by-step explanation:
Let the number of white balloons = x
The cost of blue balloons and white balloons are 60 cent = $0.6 and 30 cents = $0.3 respectively.
Wei purchased 100 blue balloons and have $150 to buy both balloons
The right triangle with angle 45 ° has adjacent leg 9 feet
So the opposite leg is calculated from
tan 45 = opposite leg / adjacent leg ⇒ adjacent leg = 9 tan 45 = 9.
That is the distance bc.
The right triangle with angle 60° has adjacent leg 9 and opposite leg (x+9), where x is the distance ab.
Then tan(60) = (x+9) / 9 ⇒x+9 = 9 tan(60)
x + 9 = 15.59
x = 15.59 - 9 = 6.59
Answer: 6.59 feet
Answer:
$56
Step-by-step explanation:
Since you are doing this for 8 weeks, you multiply 8 by 18 and you get 144. You then subtract 144 from 200 and get 56 dollars.
Hope this helped!
Answer:
0.3 or 30%
Step-by-step explanation:
The professors will only seek a smaller publisher if they cannot place the statistics book with a major publisher. If the probability of getting a major publisher is 40% and the probability of getting a smaller publisher is 50%, then the probability that the statistics book would wind up being placed with a smaller publisher is given by:
The probability is 0.3 or 30%.
Answer: 8 7/10 hours
whole part = 8
fractional part = 7/10
========================================================
Work Shown:
x = number of hours driving
(5/6)x = total number of gallons of gas used
(5/6)x = 7 & 1/4
(5/6)x = 7 + 1/4
(5/6)x = 28/4 + 1/4
(5/6)x = 29/4
x = (29/4)*(6/5)
x = (29*6)/(4*5)
x = 174/20
x = 87/10
x = (80+7)/10
x = 80/10 + 7/10
x = 8 + 7/10
x = 8 & 7/10
This is the same as writing 8 7/10
Amy drove 8 full hours, plus an additional 7/10 of an hour.
That mixed number converts to the decimal value 8.7
