A tree that grows 3 feet every 5 years is growing at a rate of ___ feet per year.'

Answers

[tex]\bf Step-by-step~explanation:[/tex]

Objective: You need to find the number of feet the tree grows every year (the unit rate).

[tex]\bf Steps:[/tex]

FIrst, we look at what we have now. The tree grows 3 feet every 5 years, so we have to divide 3 by 5 to get the number of feet the tree grows in one year.

[tex]\bf 3~feet~divided~by~5~years~=~Our~final~answer\\\frac{3}{5}=\frac{6}{10}~(multiplied~3~and~5~by~2)\\ \frac{6}{10} =0.6~feet[/tex]

Karen sells tickets at a movie theater. Last night she sold 128 tickets for a total of $1108. Adult's tickets cost $10 and children's tickets cost $6. How many of each kind of ticket did Karen sell?

Answers

Answer:

Adult's tickets 85

children's tickets 43

Step-by-step explanation:

x + y = 128

10x + 6y = 1108

x = 128 - y

10(128 - y) + 6y = 1108

1280 - 10y + 6y = 1108

1280 - 4y = 1108

-4y = 1108 - 1280

-4y = -172

y = -172/-4

y = 43

x = 128 - y

x = 128 - 43

x = 85

The area of a rectangular wall of a barn is 252 square feet. Its length is 10 feet longer than twice its width. Find the length and width of the wall of the barn.

Answers

Answer: Length = 28 feet and width = 9 feet

Step-by-step explanation:

Let x = width of the wall.

Then, Length of the wall =  10+2x

Since , Area of rectangle = length x width

Then, as per given,

[tex]252= (10+2x)x\\\\\Rightarrow\ 252=10x+2x^2\\\\\Rightarrow\ 2x^2+10x-252=0\\\\\Rightarrow\ x^2+5x-126=0\\\\\Rightarrow\ x^2+14x-9x-126=0\\\\\Rightarrow\ (x+14)-9(x+14)=0\\\\\Rightarrow\ (x+14)(x-9)=0\\\\\Rightarrow\ x=-14 \ or \ x= 9[/tex]

Since width cannot be negative , so x = 9

So width = 9 feet and length = 10+2(9)=10+18 = 28 feet

Hence, length is 28 feet and width is 9 feet of the wall of the barn.

Answer:

Step-by-step explanation:

The water volume in pool 1 starts at 50 gallons and increases at 2.3 gallons per minute. An expression for that volume could be ...

  v = 50 +2.3t

The water volume in pool 2 starts at 102.2 gallons and decreases at 3.5 gallons per minute. An expression for that volume could be ...

  v = 102.2 -3.5t

The volumes will be equal when ...

  50 +2.3t = 102.2 -3.5t

  5.8t = 52.2 . . . . . . . . . . . subtract 50-3.5t from both sides

  t = 52.2/5.8 = 9 . . . . . . . divide by the coefficient of t

After 9 minutes, the pools will contain the same amount of water.

_____

The equation 5.8t = 52.2 tells you the 52.2 gallon difference in volumes is being reduced at the rate of 5.8 gallons per minute. You don't really need the 'v' equations to figure that out.

A researcher randomly selected 30 people to participate in a study to investigate which of two materials, A or B, used in the heels of sneakers will last longer. The researcher is considering two design types for the study.

Design 1: Randomly assign 15 participants to wear sneakers with material A on their left feet and material B on their right feet. The remaining participants will wear sneakers with material B on their left feet and material A on their right feet.
Design 2: Randomly assign 15 participants to wear sneakers with material A on both feet and the remaining participants to wear sneakers with material B on both feet.
Which of the following best describes each design?

Answers

Answer:

Design 1

Step-by-step explanation:

Design one would work better because the students get to see both materials (each on one foot) and if they do the same things each day with both feet, they can test how the material works with the activity...If that makes sense

The question is an illustration of a random selection.

The descriptions of the designs are:

Design 1 is a matched pair designDesign 2 is a completely randomized design.

Design 1

From the question, we understand that:

15 participants wear material A on the left feet, and material B on the right feet.The other 15 wear material B on the left feet, and material A on the right feet.

The above description is a matched pair design, because half of the participants gets randomly assigned to material A and B, while the other half gets automatically assigned to the remaining materials.

Design 2

From the question, we understand that:

15 participants wear material A on both feetThe other 15 wear material B on both feet

The above description is a completely randomized design, because half of the participants gets randomly assigned to material A, while the other half gets randomly assigned to material B.

=======================================================

Explanation:

Fractions are a pain to deal with, so whenever possible I recommend you eliminate them. With equations like this, you can multiply both sides by the same number to do so. The question is: which number would that be?

If you pick on the LCD, then you'll be able to clear out the fractions. The LCD of 1/2, 1/3, and 5/6 is 6 since the LCM of the denominators is 6.

Multiply both sides by 6 to get

(1/2)x - 1/3 = 5/6

6*[ (1/2)x - 1/3 ] = 6(5/6)

6*(1/2)x - 6*(1/3) = 6(5/6)

3x - 2 = 5

------------

At this point, the fractions are gone. We can now solve like so

3x-2 = 5

3x-2+2 = 5+2 ... adding 2 to both sides

3x = 7

3x/3 = 7/3 .... dividing both sides by 3

x = 7/3

Combine 1212 and xx.

Move all terms not containing xx to the right side of the equation.

Add 1313 to both sides of the equation.

x2=56+13x2=56+13

To write 1313 as a fraction with a common denominator, multiply by 2222.

x2=56+13⋅22x2=56+13⋅22

Write each expression with a common denominator of 66, by multiplying each by an appropriate factor of 11.

Multiply 1313 and 2222.

x2=56+23⋅2x2=56+23⋅2

Multiply 33 by 22.

x2=56+26x2=56+26

Combine the numerators over the common denominator.

x2=5+26x2=5+26

Add 55 and 22.

x2=76x2=76

Multiply both sides of the equation by 22.

D. 0.4

Total customers at Becky's restaurant = 25

Customers who order wheat rolls = 10

It means 10 out of 25 customers order wheat rolls

That is

10 / 25

Dividing both numerator and denominator by 5

Point K is on line segment JL. Given JK = 5x + 7, JL = 2x+8, and KL = 4,

determine the numerical length of JL.

Answers

Answer:

The numerical length of JL is 6 units

Step-by-step explanation:

Here, we want to determine the numerical length of JL

Mathematically;

JL = JK + KL

2x + 8 = 5x + 7 + 4

2x + 8 = 5x + 11

5x -2x = 8-11

3x = -3

x = -1

But JL = 2x + 8

JL = 2(-1) + 8 = -2 + 8 = 6

The solution is, he will pay 7000000 interest in all.

What is interest?

Interest is the price you pay to borrow money or the cost you charge to lend money. Interest is most often reflected as an annual percentage of the amount of a loan. This percentage is known as the interest rate on the loan.

Here, we have,

formula: I = Prt.

here, we have,

given that,

Antony borrowed 20,000,000 for 7 years his interest rate is 5%

i.e. we get,

P= 20,000,000

t = 7

r= 5%

and, we have to find I

so, we have,

I = P r t

 =20,000,000*5*7/100

 =7000000

Hence, he will pay 7000000 interest in all.
