John takes one step every second, and each step is 33 inches long. How many miles per hour is John walking, given that 5280 feet = 1 mile? Express your answer as a decimal to the nearest thousandth.
Answers
Answer:
[tex]Speed = 1.875 miles/hour[/tex]
Step-by-step explanation:
Given
[tex]Speed = 33in/s[/tex]
Required
Convert to mile/hour
[tex]1\ inch = 1/63360\ mile[/tex]
[tex]1\sec = 1/3600\ hr[/tex]
So:
[tex]Speed = 33in/s[/tex]
[tex]Speed = \frac{33 * 1/63360}{1/3600}[/tex]
[tex]Speed = \frac{33/63360}{1/3600}[/tex]
[tex]Speed = \frac{33}{63360}/\frac{1}{3600}[/tex]
[tex]Speed = \frac{33}{63360} * \frac{3600}{1}[/tex]
[tex]Speed = \frac{33 * 3600}{63360}[/tex]
[tex]Speed = \frac{118800}{63360}[/tex]
[tex]Speed = 1.875 miles/hour[/tex]
Hence, John is working at 1875 miles per hour
Answer:
1.875 a hour
Step-by-step explanation:
It is this way because 33/12 is 2.75 so he is walking 2.75 feet a second
Multiply the second by 3600 and the 2.75 feet by 3600 and you get 9900
per hour divide 9900 by 5280 and you get 1.875
Write −2.32
as a mixed number in simplest form
Answers
Answer:
first I put -2.32 into a improper fraction and then I simplified to this - 2 8/25
We need to find the given numbers mixed fraction representation.
The given numbers mixed fraction form is [tex]-2\dfrac{8}{25}[/tex].
The given number is [tex]-2.32[/tex].
Let us remove the negative sign for solving the question.
The negative sign can be added at the end.
[tex]2.32=2+0.32[/tex]
[tex]=2+\dfrac{32}{100}[/tex]
Dividing the fraction by common factors we get
[tex]2+\dfrac{8}{25}=2\dfrac{8}{25}[/tex]
The given numbers mixed fraction form is [tex]-2\dfrac{8}{25}[/tex].

A hockey player strikes a hockey puck. The height of the puck increases until it reaches and maximum height of 3 feet, 55 feet away from the player. The height y (in feet) of a second hockey puck is modeled by y=x(0.15-0.001x), where x is the horizontal distance (in feet). Compare the distances traveled by the hockey pucks before hitting the ground.
Answers
Answer:
Distance traveled by hockey puck of second player is 40 feet more than that of first player.
Step-by-step explanation:
Maximum height of 3 feet is attained by the hockey puck of first player is when the puck is 55 feet away from the player.
It is at the mid point of the total horizontal distance to be traveled by the hockey puck.
So, the horizontal distance traveled by hockey puck of first player = 55 + 55 = 110 feet
Second player:
[tex]y=x(0.15-0.001x)[/tex]
where [tex]y[/tex] is the height of a second hockey puck
[tex]x[/tex] is the horizontal distance.
When the puck hits the ground, [tex]y=0[/tex]
Now, let us find the value of [tex]x[/tex].
[tex]\Rightarrow 0=x(0.15-0.001x)[/tex]
At [tex]x=0[/tex] feet or [tex]x=150[/tex] feet, [tex]y=0[/tex]
Therefore, the distance traveled by second hockey puck is 150 feet.
So, the answer is:
Distance traveled by hockey puck of second player is 40 feet more than that of first player.

A fruit company recently released a new applesauce. By the end of its first year, profits on this product amounted to $ 35 comma 900.$35,900. The anticipated profit for the end of the fourth year is $ 44 comma 300.$44,300. After the first year, the ratio of change in time to change in profit is constant. Let x be years and P be profit in dollars. A. Write a linear function P(x) that expresses profit as a function of time.
Answers
Answer:
P(x) = 35,900 + 2,800(x-1)
Step-by-step explanation:
P(x)
P(1) = $35,900
P(4) = $44,300
Difference in profits
P(4) - P(1)
= P(3)
= $44,300 - $35,900
= $8,400
Rate of change per year = $8,400 / 3
= $2,800 per year
The linear equation
P(x) = 35,900 + 2,800(x-1)
Where
x = number of years

Cooper Middle School has a goal of collecting more than 1,000 cans of food in a food drive. So far, 375 cans have been collected. During the last 13 days of the drive, at least how many cans must be collected each day in order to meet the goal?
Answers
Answer:
48 cans each day
Step-by-step explanation:
This can be represented as:
[tex]375+13c\geq 1,000[/tex]
(13c represents the number of cans, needed within the past 13 days)
First subtract both sides by 375
[tex]13c\geq 625[/tex]
Then divide both sides by 13 to get your answer of:
[tex]c\geq 48[/tex]
Answer:
48
Step-by-step explanation:
1000-375=625
625/13=48.0769

Mis the midpoint of CD. Given
the coordinates of one endpoint
C(10,-5) and the midpoint
M(4,0), find the coordinates of
the other endpoint D of CD.
a) (7.)
b) (-2)
c) (-2,5)
d) (7,5)
e) (1,1)
Answers
Answer:
(-2,5)
Step-by-step explanation:
use formula: m= ([tex]\frac{x^{1}+x^{2} }{2} , \frac{y^{1}+y^{2} }{2}[/tex])
midpoint(m) equals (4,0) and C is (10,-5)
C represents [tex](x^{1} ,y^{1})[/tex] and other endpoint D represents [tex](x^{2}, y^{2} )[/tex] so:
(4,0) = [tex](\frac{10+x^{2} }{2} , \frac{-5+y^{2} }{2} )[/tex]
4 = [tex]\frac{10+x^{2} }{2}[/tex]
[tex]4*2 = (\frac{10+x^{2} }{2} )2[/tex] Get rid of 2 by multiplying both sides by 2
8 = [tex]10 + x^{2}[/tex] Subtract both sides by 10
[tex]x^{2} = -2[/tex] x coordinate of D = -2
To find y coordinate of D:
0 = [tex]\frac{-5+y^{2} }{2}[/tex] Get rid of 2 by multiply both sides by 2
0 = [tex]-5 + y^{2}[/tex] Add both sides by 5
[tex]y^{2} = 5[/tex] y coordinate of D = 5
So if x-coordinate of D= -2 and y-coordinate of D=5, the coordinates for D is (-2,5)

Sally deposits $4,000 in a certificate of deposit that pays 2.12% simple interest. What is her balance after one year?
Answers
Answer:
4084.80
Step-by-step explanation:
Interest = Principal * Interest * Time
= 4000 * 0.0212 * 1
= 84.8
balance = deposit amount + interest
= 4000 + 84.8
= 4084.80
Based on then information given her balance after one year is: $4048.80.
Using this formula
A = P (1 + r)^t
Where:
A=Amount=?
Principal=$4,000
r=Interest rate=2.12% or 0.0212
t=time=1 year
Let plug in the formula
A=4000(1 + 0.0212)^1
A= 4000(1.0212)
A= $4048.80
Inconclusion her balance after one year is: $4048.80.

Frank liked to buy packs of baseball cards. On 3 different days, he bought 3 packs. On 3 other days, he bought 4 packs each day. After that he split his packs with his 2 brothers. How many packs will they each have? Choose the expression that best matches this situation. [(3 x 3) + (4 x 3)] ÷ 3 [(3 x 3) + (4 x 3)] - 3 (3 x 3) + [(4 x 3) ÷ 3] [(3 x 3) + (4 x 3) ÷ 3]
Answers
Answer:
[(3 x 3) + (4 x 3)] ÷ 3
Step-by-step explanation:
Choose the expression that best matches this situation.
[(3 x 3) + (4 x 3)] ÷ 3
[(3 x 3) + (4 x 3)] - 3
(3 x 3) + [(4 x 3) ÷ 3]
[(3 x 3) + (4 x 3) ÷ 3]
On 3 different days, he bought 3 packs
= 3 × 3
= 9 packs
On 3 other days, he bought 4 packs each day.
= 4 × 3
= 12 packs
After that he split his packs with his 2 brothers
= (9 + 12) / 3
= 21 / 3
= 7 packs each for him and his two brothers
Here is the expression:
[(3 x 3) + (4 x 3)] ÷ 3
= (9 + 12) ÷ 3
= 21 / 3
= 7 packs
