The number of revolution each wheel make is 5605.
What is a circle?A circle is a two-dimensional figure with a radius and circumference of 2πr.
The area of a circle is given as πr².
We have,
Diameter of the wheel = 36 inches
The radius of the wheel = 18 inches
The circumference of the wheel = 2πr.
The total distance traveled = Circumference of the wheel x Number of revolutions (N).
Now,
10 miles = 10 x 5280 ft = 10 x 5280 x 12 inches
10 miles = 2πr x N
N = (10 x 5280 x 12) / (2 x 3.145 x 18)
N = 633600 / 113.04
N = 5605
Thus,
The number of revolutions is 5605.

A baby giraffe is about 612 feet tall at birth and grows about 12 foot per month for its first year. The function h=12m+612 represents the total height h of a baby giraffe for any number of months m within its first year. How much taller is the giraffe at the end of month 11 than at the end of month 2? write your answer as a whole number, fraction, or decimal.
4 and 1/2 ft taller is the giraffe at the end of month 11 than at the end of month 2.
The function h(m) = (1/2)*m + (6 + 1/2) represents the height (on feet) of the giraffe as a function of the number of months, m.
We want to find the difference in the height between month 11 and month 2, then we need to find:
difference = h(11) - h(2)
We can directly calculate this:
difference = [ (1/2)*11 + (6 + 1/2)] - [(1/2)*2 + (6 + 1/2)]
difference = (1/2)*11 - (1/2)*2 = (1/2)*(11 - 2) = (1/2)*(9) = 9/2
And we can write 9 = 9 + 1, then:
difference=9/2 = (8 + 1)/2 = 8/2 + 1/2
difference= 4 + 1/2
Therefore, the giraffe is (4 and 1/2) ft taller in month 11 than in month 2.

By understanding the property of circles, it can be concluded that the measurement of dimension A is 1 1/4".
Circle is a geometric shape in which all the constituent points are at a certain distance from the center point. A circle has a diameter that shows the maximum distance between any two points of the circle. Whilst the radius is half the diameter.
Now we take a look at the picture thoroughly.
The width of the manufactured part =
the diameter of the circle on the far left = 2 * the radius
= 2 * 1"
= 2"
This value is equal to the sum of A, the radius of the circle at the very bottom (1/2"), and the space between this circle and the edge (1/4"). We write it down mathematically:
2" = A + 1/2'' + 1/4''

Joseph has a loyalty card good for a 20% discount at his local pharmacy. What would his total in dollars and cents be, after the discount and before tax, if the total cost of all the items he wants to buy is $42.05? Round to the nearest cent.
Answer:
$33.64
If this help please set brainliest.
Step-by-step explanation:
The total cost of all the items before the discount is $42.05. The discount Joseph receives is 20% of this amount, so the discount he receives is $42.05 * 20% = $8.41.
The total cost after the discount is applied is $42.05 - $8.41 = $33.64. This is the total cost in dollars and cents, before tax, rounded to the nearest cent.

The position value, r(t) is equals to the (t³/6)k + 2j and velocity value, v(t) is equals to ( t²/2 )k + 4i , for a(t) = tk, v(0) = 4i, r(0) = 2j.
Acceleration is defined as the rate of change of the velocity of an object with respect to time. Accelerations are vector quanty.
a = dv/dt
We have the following informations are available,
Initial velocity, v(0) = 4i
Initial position, r(0) = 2j
Acceleration at any time "t",
a(t) = tk
we have to determine the value of v(t) and r(t).
As we know, a(t) = dv(t)/dt = tk
integrating the above equation ,
v(t) = ∫tk dt = ( t²/2 )k + c
at t = 0 , v(0) = 0 + c = 4i ( since, v(0) = 4i
=> c = 4i
So, v(t) = ( t²/2 )k + 4i
Also, velocity is calculated by derivative of postion (r) with respect to time.
=> v(t) = dr(t) /dt
=> r(t) = ∫ v(t) dt
=> r(t) = ∫ ( t²/2 )k dt
integrating value of the right hand side,
r(t) = ( t³/2×3 )k +d
= (t³/6)k + d
At t = 0, r(0) = (0/6)k + d
=> r(0) = d = 2j
so, r(t) = (t³/6)k + 2j
Hence, the required position and velocity are
(t³/6)k + 2j and ( t²/2 )k + 4i.

Kala is putting money into a savings account. She starts with $750 in the savings account, and each week she adds $70. Let S represent the total amount of money in the savings account (in dollars), and let W represent the number of weeks Kala has been adding money. Write an equation relating S to W. Then use this equation to find the total amount of money in the savings account after 11 weeks.
Answer:
$1520
Step-by-step explanation:
The total amount of money in the savings account after W weeks is equal to the initial amount of money, $750, plus the amount of money added each week for W weeks. We can represent this relationship with the following equation:
S = 750 + 70W
To find the total amount of money in the savings account after 11 weeks, we can substitute 11 for W in the equation above:
S = 750 + 70(11)
= 750 + 770
= 1520
Therefore, the total amount of money in the savings account after 11 weeks is $1520.
Answer:
$1520
Step-by-step explanation:
S = $750 + $70W
S = $750 + $70(11) = $1520

At the beginning of the day, Hasim counted his money. He gave his brother 1/3 of his money. He spent £12 on a present for his sister. He then counted what he had left, and it was half what he had at the beginning of the day. How much did he give his brother? Show your method.
Answer: the answer is £12.
Step-by-step explanation:
To solve this problem, we can set up an equation to represent the information given in the problem. Let's call the amount of money Hasim had at the beginning of the day x.
We know that Hasim gave his brother 1/3 of his money, so we can represent that with the equation:
x / 3 = y
Where y is the amount of money Hasim gave to his brother.
We also know that Hasim spent £12 on a present for his sister, so we can subtract that amount from x to find the amount of money he had left:
x - 12 = z
Where z is the amount of money Hasim had left after buying the present.
Finally, we are told that the amount of money Hasim had left is half of what he had at the beginning of the day, so we can represent that with the equation:
x / 2 = z
Now we have three equations that all involve the variable x. We can solve for x by substituting the first equation into the second and third equations:
x / 3 = x - 12
x / 2 = x / 3
Solving these equations, we find that x = 36.
This means that Hasim had £36 at the beginning of the day, and gave his brother £36 / 3 = £<<36/3=12>>12.

-4x + 4y = 4 Eq. 1
y = 3x + 9 Eq. 2
Replacing Eq. 2 in Eq. 1:
-4x + 4(3x+9) = 4
-4x + (4*3x + 4*9) = 4

8x + 36 = 4
8x = 4 - 36
8x = -32
x = -32/8
x = -4
From Eq. 2
y = 3*-4 + 9
y = -12 + 9
y = -3

Peter is making an "x marks the spot" flag for a treasure hunt. The flag is made of a square white flag with sides of 121212 centimeters. He will make the "x" by stretching red ribbon diagonally from corner to corner. How many centimeters of ribbon will peter need to make the "x"? round your answer to the nearest centimeter. Centimeters.
Peter will need approximately 169169 centimetres of red ribbon to make the "x" on his flag. Rounded to the nearest centimetre, this is 169200 centimetres.
To find the length of the red ribbon needed to make the "x" on the flag, we need to find the length of the diagonal of the square. The diagonal of a square is a line segment that connects two opposite corners of the square and passes through the centre of the square.
The diagonal of a square can be found using the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. In the case of a square, the two shorter sides of the right triangle are equal in length to the sides of the square, so the Pythagorean theorem can be written as:
[tex]a^2 + a^2 = c^2[/tex]
Where "a" is the length of a side of the square and "c" is the length of the diagonal.
To find the length of the diagonal of Peter's flag, we can substitute 121212 for "a" in the equation above:
[tex](121212)^2 + (121212)^2 = c^2[/tex]
Solving for "c" gives us:
c = 169169 centimetres
Therefore, Peter will need approximately 169169 centimetres of red ribbon to make the "x" on his flag. Rounded to the nearest centimetre, this is 169200 centimetres.
