Paj is filling a 9-cubic-inch flower pot with soil from small bags. Each bag of soil contains 2 2/3
cubic inches of soil. Exactly how many bags of soil are needed for Paj to fill the flower pot?
Answer:
3.375 bags of soil are needed for Paj to fill the flower pot
Step-by-step explanation:
This question can be solved using a rule of three.
One bag contains 2 + (2/3) = (8/3) cubic inches of soil. How many bags are needed to fill 9 cubic inches of soil?
1 bag - (8/3) cubic inches
x bags - 9 cubic inches
[tex]\frac{8x}{3} = 9[/tex]
[tex]8x = 27[/tex]
[tex]x = \frac{27}{8}[/tex]
[tex]x = 3.375[/tex]
3.375 bags of soil are needed for Paj to fill the flower pot
Paj needs 3.375 bags of soil to fill the bag.
Each bag contains 2²/₃ inch³ of soil and they need to fill up a 9 inch³ pot of soil.
First convert the mixed fraction to an improper one:
2²/₃ = 8/3
The number of bags needed is:
= Volume of pot / Quantity of soil in each bag
= 9 ÷ 8/3
= 9 x 3/8
= 3.375 bags of soil
Paj therefore needs 3.375 bags of soil to fill the pot

Answer:
g=56
Step-by-step explanation:
In similar shapes, corresponding sides are always in the same ratio.
For example,
if the sides in triangle 1 were a and b, and triangle 2 had side lengths c and d, c and a had the same ratios, and b and d had the same ratios
and triangle 1 was similar to triangle 2, the ratio between the sides of the triangles would be
a/c, which is also equal to b/d
What that means is that in this situation, 8/5=g/35.
8/5=g/35
Cross multiply.
(8)*(35)=g*(5)
280=5g
g=56
For the given functions, (a) express dw/dt as a function of t, both by using the chain rule and by expressing w in terms of t and differentiating directly with respect to to Then (b) evaluate dw/dt at the given value of t. w = 7y e^x - Inz,x = ln(t^2 + 1), y = tan^-1t,z=e^t;t = 1
(a) dw/dt =?
By the chain rule,
[tex]\dfrac{\mathrm dw}{\mathrm dt}=\dfrac{\partial w}{\partial x}\dfrac{\mathrm dx}{\mathrm dt}+\dfrac{\partial w}{\partial y}\dfrac{\mathrm dy}{\mathrm dt}+\dfrac{\partial w}{\partial z}\dfrac{\mathrm dz}{\mathrm dt}[/tex]
We have

and
[tex]\begin{cases}x=\ln(t^2+1)\\y=\tan^{-1}t\\z=e^t\end{cases}\implies\begin{cases}\dfrac{\mathrm dx}{\mathrm dt}=\dfrac{2t}{t^2+1}\\\\\dfrac{\mathrm dy}{\mathrm dt}=\dfrac1{t^2+1}\\\\\dfrac{\mathrm dz}{\mathrm dt}=e^t\end{cases}[/tex]
Putting everything together, we get
[tex]\dfrac{\mathrm dw}{\mathrm dt}=\dfrac{14ye^xt}{t^2+1}+\dfrac{7e^x}{t^2+1}-\dfrac{e^t}z[/tex]
[tex]x=\ln(t^2+1)[/tex], so [tex]e^x=e^{\ln(t^2+1)}=t^2+1[/tex], and [tex]z=e^t[/tex], so [tex]\frac{e^t}z=1[/tex].

4) The average weight of the bags = (3/11) of an ounce.
Step-by-step explanation:
Complete Question
Raine divides three 2-ounce bags of rice into smaller bags. The first bag is divided into bags weighing 1/6-ounce each, the second bag is divided into bags weighing 1/3-ounce each and the third bag is divided into bags weighing 1/2- ounce each. Find the number of 1/6, 1/3 and 1/2 bags and graph it in a line plot.
1) How many bags weigh at least 1/6 of an ounce?
2) How many bags are more than 1/3 of an ounce?
3) What is the combined total of the 1/2 ounce bags?
4) What is the average weight of each of the bags?
Solution
Let the number of 1/6-ounce, 1/3-ounce and 1/2-ounce bags be x, y and z respectively.
(1/6) × x = 2
x = 2 × 6 = 12 bags of 1/6-ounce rice.
(1/3) × y = 2
y = 2 × 3 = 6 bags of 1/3 ounce of rice.
(1/2) × z = 2
z = 2 × 2 = 4 bags of 1/2-ounce rice.
The line plot is presented in the attached image to this answer.
1) All of the bags weigh at least 1/6 of an ounce. Hence, the number of bags that weigh more than 1/6 of an ounce = 12 + 6 + 4 = 22 bags
2) The bags that weigh more than 1/3 of an ounce are the 1/2-ounce bags, and there are only 4 of them. Hence, 4 bags weigh more than 1/3 of an ounce.
3) Combined total of the 1/2 ounce bags
= 4 bags × (1/2-ounce per bag) = 2 ounces.
4) The average weight of the bags is given as the sum total of the weight of the bags divided by the number of bags.
Total weight of the bags = [12 × (1/6)] + [6 × (1/3)] + [4 × (1/2)] = 2 + 2 + 2 = 6 ounces.
Total Number of bags = 12 + 6 + 4 = 22 bags
Average weight of the bags = (6/22) = (3/11) ounce per bag.

In the diagram below, RSTU is a rectangle, and the two shaded regions are squares.
If the length of SR is 4 m and the length of ST is 8 m, what is the length of PQ in meters?
Answer:
length PQ = 8.9 m
Step-by-step explanation:
The picture below completes the question you asked. From the picture above RSTU is a rectangle . The two shaded square has a length of sides 8 m and 4 m respectively. The legs of the triangle is the sides of the 2 squares. Therefore, the triangle is a right angle triangle. The adjacent side is 4 m while the opposite side is 8 m.
Using Pythagoras theorem the hypotenuse of the triangle can be calculated below.
Pythagoras theorem
c² = a² + b² Therefore,
c² = 4² + 8²
c² = 16 + 64
c² = 80
square root both sides
c = √80
c = 8.94427191
c ≈ 8.9 m
length PQ = 8.9 m

William and Stephanie are painting the bedrooms in their house. If he had to paint the bedrooms himself, it would take William four hours to complete the job. If Stephanie alone were to paint the bedrooms, it would take her six hours.
Working together, how long will it take William and Stephanie to paint the bedrooms?
William can do 1/4 of the job every hour by himself.
Stephanie can do 1/6 of the job every hour by herself.
If they don't distract each other while working together, they can do (1/4 + 1/6) of the job every hour.
That's (3/12 + 2/12) = 5/12 job per hour working together.
The complete job will take them (12/5) hour .
That's 2-2/5 hours, or 2 hours 24 minutes.
They both can do the painting in 2hours 24 minutes by solving the fraction.
What is a fraction?
It is a combination of numerator and denominator. It is always in decimal
if solved properly.
How to calculate time?William can do 1/4 of the job every hour himself. Stephanie can do 1/6 of the job every hour herself, they can do (1/4 + 1/6) of the job every hour.
That's (3/12 + 2/12) = 5/12 job per hour working together.

NEXT QUESTION
ASK FOR HELP
Answer:
2 nickels
6 quarters
Step-by-step explanation:
Let quarters be 3x and nickels be $x
if Mark had 3 times as many quarters as nickels, and if he had $1.60 in all, than
( 0.25)3x + 0.05x=1.6
0.75x+ 0.05x=1.6
0.8x=1.6
x=1.6/0.8
x=2 nickels
and 3 (2)=6 quarters
Answer:
There are 4 quarters and 12 nickels.
Step-by-step explanation:
A quarter is equal to $0.25.
A nickel is equal to $0.05.
Let the number of nickels be y.
Let the number of quarters be x.
Mark had 3 times as many quarters as nickels. This means that:
y = 3x
3x represents the number of nickels.
We are told that he had $1.60 in all. This means that:
0.25x + 0.05y = 1.60
=> 0.25x + 0.05 * 3x = 1.60
0.25x + 0.15x = 1.60
0.40x = 1.60
=> x = 1.6 / 0.4 = 4
Therefore:
y = 3 * 4 = 12
There are 4 quarters and 12 nickels.
In a science fair project, Emily conducted an experiment in which she tested professional touch therapists to see if they could sense her energy field. She flipped a coin to select either her right hand or her left hand, and then she asked the therapists to identify the selected hand by placing their hand just under Emily's hand without seeing it and without touching it. Among 329 trials, the touch therapists were correct 154 times.
a. Given that Emily used a coin toss to select either her right hand or her left hand, what proportion of correct responses would be expected if the touch therapists made random guesses?
b. Using Emily's sample results, what is the best point estimate of the therapists' success rate?
c. Using Emilys sample results, construct a 90% confidence interval estimate of the proportion of correct responses made by touch therapists.

[tex] p = 0.5[/tex]
Part b
For this case the proportion of success is given by:
[tex] \hat p= \frac{X}{n}= \frac{154}{329}= 0.468[/tex]
Part c
The confidence interval for the true proportion would be given by this formula

Mike took clothes to the cleaners three times last month. First, he brought 4 shirts and 1 pair of slacks and paid $15.95. Then he brought 7 shirts, 4 pairs of slacks, and 1 sports coat and paid $49.38. Finally, he brought 3 shirts and 1 sports coat and paid $15.46. How much was he charged for each shirt, each pair of slacks, and each sports coat? Mike was charged $ nothing for each shirt, $ nothing for each pair of slacks, and $ nothing for each sports coat.
Answer:
Each Shirt ≈ $2.49
Each Pair of Slacks ≈ $5.99
Each Sports Coat ≈ $7.99
Step-by-step explanation:
Mike took clothes to the cleaners three times last month.
Let S denotes shirts, P denotes pair of slacks and C denotes sports coat.
First, he brought 4 shirts and 1 pair of slacks and paid $15.95.
Mathematically,
4S + P = 15.95 eq. 1
Then he brought 7 shirts, 4 pairs of slacks, and 1 sports coat and paid $49.38.
Mathematically,
7S + 4P + C = 49.38 eq. 2
Finally, he brought 3 shirts and 1 sports coat and paid $15.46.
Mathematically,
3S + C = 15.46 eq. 3
We are asked to find how much was he was charged for each shirt, each pair of slacks, and each sports coat.
4S + P + 0C = 15.95 eq. 1
7S + 4P + C = 49.38 eq. 2
3S + 0P + C = 15.46 eq. 3
We have 3 equations and 3 unknowns, they can be solved simultaneously using calculator or using online system of equations solver.
Using online system of equations solver yields,
S ≈ $2.49
P ≈ $5.99
C ≈ $7.99
So that means Mike was charge $2.49 for each shirt, $5.99 for each pair of slacks and $7.99 for each sports coat.
Which inequality is true if p=3.4
3p<10.2
13.6<3.9p
5p>17.1
8.5>2.5
Answer:
None of the inequalities are correct if p = 3.4
Step-by-step explanation:
Mathematical inequality is an order relation proposition existing between two algebraic expressions connected through the signs: unequal than ≠, greater than>, less than <, less than or equal to ≤, as well as greater than or equal to ≥, resulting in both expressions of different values. That is, an inequality is a relationship that exists between two quantities or expressions and, which indicates that they have different values.
To check an inequality, you must replace the inequality variable with the value of the solution. In this case, being p=3.4, you must do it with each of the inequalities, as shown below:
A. 3p<10.2 ⇒ 3*3.4<10.2 ⇒ 10.2 <10.2
This inequality is not true, because 10.2 is not less than 10.2, but they are equal.
B. 13.6<3.9p ⇒ 13.6<3.9*3.4 ⇒ 13.6<13.26
This inequality is not true, because 13.6 is greater than 13.26 and not less as the inequality shows.
C. 5p>17.1 ⇒ 5*3.4 >17.1 ⇒ 17 > 17.1
This inequality is not true, because 17 is less than 17.1 and not greater as the inequality shows.
D. 8.5> 2.5p ⇒ 8.5 >2.5*3.4 ⇒ 8.5 > 8.5
This inequality is not true, because 8.5 is not less than 8.5. These values are the same.
None of the inequalities are correct if p = 3.4
The correct answer is C. By substituting the greatest number in each set for p, you can quickly tell which sets make the inequality false.
