the wheels on Kiran's bike are 64 inches in circumference. How many times doo the wheels rotate if Kiran rides 300 yards ?
Answer:
169 times
Step-by-step explanation:
We know that the circumference of Kiran's bike wheel is 64 inKiran rides total distance of 300 yardsTo find number of rotations made by wheel...
Know that 1 yard = 36 in
300 yards = 36 x 300 = 10800 in
Number of rotation = Total distance covered by wheel ÷ Circumference of wheel
Number of rotations = 10800 ÷ 64 = 168.75 ≅ 169
Therefor, the wheel rotates = 169 times

Subtraction:
Subtraction represents the operation of removing objects from a collection. The minus sign signifies subtraction −. For example, there are nine oranges arranged as a stack (as shown in the above figure), out of which four oranges are transferred to a basket, then there will be 9 – 4 oranges left in the stack, i.e. five oranges. Therefore, the difference between 9 and 4 is 5, i.e., 9 − 4 = 5. Subtraction is not only applied to natural numbers but also can be incorporated for different types of numbers.
The letter "-" stands for subtraction. Minuend, subtrahend, and difference are the three numerical components that make up the subtraction operation. A minuend is the first number in a subtraction process and is the number from which we subtract another integer in a subtraction phrase.

Find the values of the variables and the measures of the angles.
Answer:
X= 29 because it is a right angle, and all right angles are = to 90, so you subtract 61 from 90.Y= 29Z= 61
Step-by-step explanation:
Answer:
Step-by-step explanation:
Summation of all angles within a triangle is equal to 180 degrees.
y+61+90=180
Therefore, y = 180-61-90 = 29 degrees
61+x = 90
Therefore, x = 90-61 = 29 degrees
z+90+29 = 180
Therefore, z = 180 - 90 - 29 = 61 degrees

As per the unitary method, the cost of 8 bottles is $6.48
Unitary Method:
Unitary method is the way of solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given,
Hawa buys 15 bottles of apple juice at the corner store for a total cost of $12.15.
Here we need to find the if each bottle costs the same amount, how much is 8 bottles of juice.
Let x be the cost of one bottle.
so, based on the unitary method we can written the situation as,
15 bottles = costs $12.15
Therefore, the cost of one bottle is.
x = 12.15/15
x = 0.81
So, the cost of 8 bottle is calculated by multiplying the cost of one bottle with 8,
Then we get,
=> 8 x 0.81

at 9:30 am andrew left exeter for portsmouth, cycling at 12 mi/h. at 10:00 am stacy left portsmouth for exeter, cycling at 16 mi/h. the distance from exeter to portsmouth is 20mi.find the time they meet
Stacey meets Andrew 1.5 hours after she starts travelling at 11:30 AM and Andrew meets Stacey 2 hours after he starts travelling at 11:30 AM.
How to solve this problem?
Stacey and Andrew in the mentioned problem will meet in a time frame only when the both have travelled equal distances in respect to another.
Given, speed at which Andrew was travelling = 12 mi/h
Speed at which Stacey was travelling = 16 mi/h
Let the time taken by Stacey be = t hours
Therefore, the time taken by Andrew = (t + 0.5) hours
When Stacey overtakes Andrew, they must have covered the same distance, therefore:
16t = 12×(t + 0.5) ⇒ 16t = 12t + 6 ⇒ 4t = 6 ⇒ t = 6/4 ⇒ t = 3/2 ⇒ t = 1.5
Therefore, Stacey meets Andrew 1.5 hours after she starts travelling at 11:30 AM and Andrew meets Stacey 2 hours after he starts travelling at 11:30 AM.

The equation of line g can be written as y=7/2x+6. Line h includes (-2,-3) and js parallel to line g. What is the equation of h?
Answer:
y = [tex]\frac{7}{2}[/tex] x + 4
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{7}{2}[/tex] x + 6 ← is in slope- intercept form
with slope m = [tex]\frac{7}{2}[/tex]
• Parallel lines have equal slopes , then
y = [tex]\frac{7}{2}[/tex] x + c ← is the partial equation of line h
to find c substitute (- 2, - 3 ) into the partial equation
- 3 = - 7 + c ⇒ c = - 3 + 7 = 4
y = [tex]\frac{7}{2}[/tex] x + 4 ← equation of line h

The sum of three consecutive even numbers is 558. What is the 1st number?
The sum of three consecutive even numbers is 558, The first number is 184.
The Sum of three consecutive even numbers is 558
We have to find the first number
Let the three consecutive even numbers be:
First number = x
Second number = x + 2
Third number = x + 4
Since their sum is 558
Therefore,
x + x + 2 + x + 4 = 558
3x + 6 = 558
3x = 558 - 6
3x = 552
Divide both sides by 3

A suit is on sale for $296.40, which is 62% less than the regular price.
What is the regular price?
Answer: The total price is $478.06
Step-by-step explanation:
For this we use regular price of the suit as x
x is 100% of the price therefore 62% of x=296.4
Now we cross multiply
62 × x = 100 × 296.40
62x = 29,640
Now that we got rid of those complicated percentages we simply divide both sides by 62 to isolate x
29,640/62 = 478.064516129
Since we are working with dollars and cents that do not get smaller than .01 we can shave off all the extra decimals near the end
478.06
The regular price is $478.06
Now we just check our work to prevent any awkward and simple mistakes
478.06 x .62 = 296.3972 or 478.06 x .62 = 296.39
Keep in mind the one cent difference is because we shaved off the extra decimals at the end

Write a system of equations with the solution (4, -3).
The system of equations with the solution (4, -3) is y = x - 7 and y = 2x - 11.
We are given a point. The coordinates of the point are (4, -3). We need to find a system of equations such that they pass through the given point.
We will use the slope-point form of a line. Let the slope of the equation of the straight line be "m". We need two equations. The general equation of a line using the slope-point form is given below.
(y - y1) = m(x - x1)
We know that both equations must pass through the given point for the solution to exist.
(y - (-3)) = m(x - 4)
(y + 3) = m(x - 4)
We just need to take any two values of the slope of the line.
First, we take m = 1. The corresponding equation is given below.
(y + 3) = m(x - 4)
(y + 3) = 1*(x - 4)
y + 3 = x - 4
y = x - 7
Next, we take m = 2. The corresponding equation is given below.
(y + 3) = m(x - 4)
(y + 3) = 2*(x - 4)
y + 3 = 2x - 8
y = 2x - 11
Hence, the system of equations is y = x - 7 and y = 2x - 11.

The proportion of heads after the first 10 tosses of a coin is zero i.e 0/10 = 0
A probability is a number that reflects the likelihood or probability that a particular event will occur. Probabilities can be expressed as percentages ranging from 0 to 1, and can also be expressed as percentages ranging from 0% to 100%. A probability of 0 indicates that the particular event is unlikely to occur, and a probability of 1 indicates that the event will definitely occur.
Probability is calculated by dividing the number of ways the event can occur by the total number of outcomes.
We have given the following points ,
A coin is tossed 10 times and it comes with tail in each time of first 10 tosses.
When a coin is toosed , there two possibilities either it comes with head or tail. Both can't be come at once.
As we see first ten tosses of a coin gives tails as a result . Then, there is no chance of occurrence head in first 10 tosses.

(x+5)-(x - 5)² for x = 3
I need to paint a straight face consisting of six panels he has a green red and magenta paint and each panel should be painted with only one color how many ways are there to paint the fence
There are 20 ways to paint the fence consisting of six panels each with one color out of green, red, and magenta.
There is a total of 6 panels and 3 paint colors and each panel has to be painted with only 1 color.
∴ Total number of panels = 6
Total number of colors = 3 (green, red, and magenta)
To calculate the number of ways to paint 6 panels with one of the 3 colors, the formula of combination is used. Combinations are ways of selecting objects from a group or collections, in a way that the order of the objects does not matter.
The number of ways or the combinations of 6 panels taken with each color out of 3 at a time is given by [tex]^6C_3[/tex]
[tex]^6C_3[/tex] = 6! / [3! (6-3)!]
[tex]^6C_3[/tex] = (6*5*4*3*2*1) / [3*2*1 (3)!]
[tex]^6C_3[/tex] = 720 / (6*6)
[tex]^6C_3[/tex] = 720 / 36
[tex]^6C_3[/tex] = 20
Therefore, 20 combinations are possible to paint 6 panels each with only one color out of green, red, and magenta.
