A cab charges $1.75 for the flat fee and $0.25 for each mile. write and solve an inequality to determine how many miles eddie ca
ad-work [718]
The answer is <span>a. $1.75 + $0.25x ≤ $15; x ≤ 53 miles
</span>
x - the number of miles
C - the cab charge

<span>A cab charges $1.75 for the flat fee and $0.25 for each mile:  C = 1.75 + 0.25x.
</span><span>Eddie has $15 to spend. So, he cannot spend more than 15 on the cab and the maximum amount he can spend is 15. Therefore:
</span>1.75 + 0.25x ≤ 15

Now, let's solve it:
0.25x ≤ 15 - 1.75
0.25x ≤ 13.25
x ≤ 13.25 / 0.25
x ≤ 53

Jane has a average score of 73% on three quizzes. What must she score on the next quiz to have an average of 78%?
Ket [755]

Answer:

93

Step-by-step explanation:

The average is calculated as

average = \frac{sum}{count}

On 3 quizzes

\frac{sum}{3} = 73 ( multiply both sides by 3 )

sum = 219

On 4 quizzes, letting x be the score on fourth test

\frac{sum+x}{4} = 78 ( multiply both sides by 4 )

sum + x = 312 , that is

219 + x = 312 ( subtract 219 from both sides )

x = 93

She must score 93 on the next quiz

erik [133]

Answer:

1. 23.0 cm

2. 21.0 ft

3. 31.0 yd

Step-by-step explanation:

1. 30/sin110 = RT/sin46

RT = sin46 × 30/sin110

RT = 22.96516279

2. Angle A = 180 - 61 - 53 = 66°

24/sin66 = AB/sin53

AB = sin53 × 24/sin66

AB = 20.98116966

3. 18/sin28 = HP/sin54

HP = sin54 × 18/sin28

HP = 31.01850475
