<h3>Inequality</h3>
75d + 30c ≥ 255
<h3>Examples</h3>
(1) If someone bought five DVD players and ten cordless telephones, the equation ((75)(5)+(30)(10)≥255) would be true.
(2) If the electronic store had a parcticularly bad day and they sold two DVD players and one cordless telephone, the equation ((75)(2)+(30)(1)≥255) would be false.
Answer:
- Distance in 47 minutes = 0.75 × 47 = 35.25 miles
- Distance in 1 hour or (60 minutes) = 0.75 × 60 = 45 miles
Step-by-step explanation:
Given that the car is traveling at a steady speed.
Distance traveled in 2 1/3 or 7/3 or (2.33) minutes = 1 3/4 miles
= 7/4 or 1.75 miles
Thus,
distance in 1 minute: 1.75/2.33 = 0.75 miles per minute
Thus,
- Distance in 47 minutes = 0.75 × 47 = 35.25 miles
- Distance in 1 hour or (60 minutes) = 0.75 × 60 = 45 miles
Answer:
4.78 pounds
Step-by-step explanation:
We solve the above question using z score formula
z = (x-μ)/σ, where
x is the raw score
μ is the population mean = 9.2 pound
σ is the population standard deviation = 3.4 pounds
z = 1.3
We are to find x
Hence,
-1.3 = x - 9.2/3.4
Cross Multiply
-1.3 × 3.4 = x - 9.2
-4.42 = x - 9.2
x = -4.42 + 9.2
x = 4.78 pounds.
Therefore the weight of the cat is 4.78 pounds
