There is a total of 27 quarters stacked in four piles. The first pile has 5 fewer than the second pile. The second pile has 4 more than the third pile. The fourth pile has three times as many as the second pile. How many quarters are in the fourth pile?
Answers
Answer: 18 quarters
Step-by-step explanation:
second pile = x
first pile = x - 5
third pile = x - 4
fourth pile = 3x
total amount of quaters = 27
x + x - 5 + x - 4 + 3x = 27
6x = 36 x = 6
fourth pile = 3(6) = 18
Solution:
Note that:
27 quarters = 4 piles = 1st pile + 2nd pile + 3rd pile + 4th pile1st pile = 2nd pile - 5 = 3rd pile - 12nd pile = 1st pile + 5 = 3rd pile + 43rd pile = 1st pile - 1 = 2nd pile - 44th pile = 3(2nd pile)This means that...
27 quarters = (2nd pile - 5) + (2nd pile) + (2nd pile - 4) + 3(2nd pile)First, let's find the number of quarters in 2nd pile.
Open the brackets.
27 quarters = (2nd pile - 5) + (2nd pile) + (2nd pile - 4) + 3(2nd pile)=> 27 quarters = 2nd pile - 5 + 2nd pile + 2nd pile - 4 + 3(2nd pile)Combine like terms.
=> 27 quarters = (-5 - 4) + 6(2nd pile)Simplify the RHS.
27 quarters = -9 + 6(2nd pile)Add 9 both sides.
27 + 9 = 6(2nd pile)=> 36 quarters = 6(2nd pile)Divide 6 both sides.
=> 6 quarters = 2nd pileNow, substitute the number of quarters in 2nd pile in it's equation.
4th pile = 3(2nd pile)=> 4th pile = 3(6)=> 4th pile = 18 quarters.please help me im dying please im only on question 12

A meteorologist recorded the rainfall in Oakdale in two consecutive months. In the first month, there were 1 6/12 inches of rain. In the second month, there were 1 inch of rain. What was the total amount of rainfall during the two months?
Answers
Answer:
There were 2 1/2 inches of rain in 2 months.
Step-by-step explanation:
1. Reduce 1 6/12 to 1 1/2.
2. Add 1 1/2 and 1 (if it is easier for you to add decimals you can reduce the 1 1/2 to 1.5 by dividing 1 by 2. In that case you would get 2.5 as your final answer). The answer is 2 1/2.

If the mountain is 1,200 feet tall, find the length of the ski lift
Answers
Step-by-step explanation;
By an online search, i found that the sky lift
rises at an angle of 20.75 degrees.
Then we can think on a triangle rectangle, such
that:
One cathetus is 1200ft, this is the opposite
cathetus to the angle of 20.75°
The length of the ski lift would be the
hypotenuse of this triangle rectangle.
Then we can use the relationship:
Sin(a) = opposite cathetus/hypoteuse.
such that:
a = 20.75°
opposite cathetus=1200ft
then:
sin(20.75°) = 1200ft/hypotenuse
hypotenuse =1200ft/sin(20.759) =3.387.05 ft
The length of the sky lift is 3.387.05 ft

A bicycle has a listed price of $811.99 before tax. If the sales tax rate is 6.5% , find the total cost of the bicycle with sales tax included.
Round your answer to the nearest cent, as necessary.
Answers
Answer:
811.99x1.065=864.77
Step-by-step explanation:
Since it is a sales tax, and not something else, we would add a 1 on the front of it, to essentially just "add" back that 811.99, even though it is multiplication. 1.065 times 811.99 is the same as (811.99x.065)+811.99.

Answers:To find the area of the unshaded region, subtract the area of the shaded region from the sum of the areas of the rectangle and semicircle
----------------
Explanation:
When it comes to area problems, think of a grid of squares. Let's say we had a 10 by 10 grid of tiny squares (10*10 = 100 total). Now let's say 8 of them are shaded in. There are 100 - 8 = 92 unshaded squares to represent the total area of the unshaded region.
That's effectively what's going on with this problem as well. Sure things get a bit tricky with that curved portion on top, but we can still get an approximation if we use smaller and smaller grid sizes. I recommend using graph paper or graphing software that provides a grid.
========================================================
Part B
Answer: 811----------------
Explanation:
For now, I'm going to ignore the shaded region. I'll come back to it later.
The rectangle is 15 ft by 50 ft. It has an area of length*width = 15*50 = 750 sq ft.
The semicircle up top has an area of [tex]0.5*\pi r^2 = 0.5*\pi*(7.5)^2 \approx 88.3573[/tex] sq ft approximately. The 7.5 is from dividing the diameter in half to get the radius. As the instructions stated, I used the calculator's version of pi.
The rectangle and semicircle have their areas add to
750+88.3573 = 838.3573
Now we can finally address the shaded region. It is a 3 ft by 9 ft rectangle because "the length is 3 times the width" and the width is 3 ft. This shaded rectangle has area 3*9 = 27 sq ft.
The unshaded region is:
unshaded = total - shaded = 838.3573 - 27 = 811.3573
This rounds to the final answer of 811

Answers
Answer:
— The total cost for a reward program member to see 5 movies is $40 and the total cost for 12 movies is $75. Assume the relationship
Step-by-step explanation:
The equation of the function is y = 5x+5, where x represents the number of movies and y represents the total cost.
What is an equation?An equation is a mathematical statement that shows that two mathematical expressions are equal.
Given that, The total cost for a reward program member to see 5 movies is $40.00 and a total costs for 12 movies is $75.00.
The coordinates of the equation can be (5, 40) and (12, 75)
The equation of a line passing from two points is given by,
y-y₁ = (y₂-y₁)/(x₂-x₁)(x-x₁)
y-40 = (75-40)/(12-5)(x-5)
y-40 = 35/7(x-5)
y = 5x-25+40
y = 5x+15
Hence, the required equation is y = 5x+15
