Answer:
Since the question requires you to give the answer in terms of steps/minute, the first step would be to convert hours to minutes:
12.5 hours = 750 minutes
Next, if he took 775 steps in 750 minutes, how many would he take in 1 minute?
This requires you to set up the question as a proportion:
(775 steps/ 750 minutes) = (x steps/1 minute)
(1 * 775)/750 = 31/30 = 1.033
he took ~1 step per minute
Answer:
$99
Step-by-step explanation:
Cost of electricity per year= $165
Tax per month= 5%
Amount of tax paid per month= 5% of $165
= 0.05 × 165
= $8.25
Ella's family pays $8.25 tax per month
There are 12 months in 1 year
Ella's family will pay Ina year = $8.25 × 12
= $99
Ella's family will pay $99 tax for an entire year
Answer:
The Ford Mustang can travel at a faster rate.
Step-by-step explanation:
160/2 = 80/1 miles/hour -Ford Mustang
210/3 = 70/1 miles/hour - Toyota Corolla
Let D be dogs and C be cats
<em>dogs, d, is initially five less than twice the number of cats, c</em>
D + 5 = 2C
<em>If she decides to add three more of each, the ratio of cats to dogs will be</em>
D + 8 = 2C + 3
<em>Could Bea's Pet Shop initially have 15 cats and 20 dogs?</em>
Simply plug in the numbers
20 + 5 = 2(15)
This is clearly not true: 25 does not equal 30

Step-by-step explanation:
If the zeros are 5 and 9, then the equation will have the form:
y = a (x–5) (x–9)
We know the point (0, 90) is on the curve, so we can use this to find the coefficient a:
90 = a (0–5) (0–9)
90 = 45a
a = 2
y = 2 (x – 5) (x – 9)
