How many ninths to make 1/3

Answers

Answer 1

Answer: Answer:
3

Explanation:
Assume that the number of $(1)/(9)$ needed to make $(1)/(3)$ is x

Now, we would need to translate the givens into an equation and then solve for x.
The number of $(1)/(9)$ multiplied by x would give us $(1)/(3)$

This means that:
$(1)/(9)$ * x = $(1)/(3)$

$(x)/(9)$ = $(1)/(3)$

3x = 9

x = $(9)/(3)$

x = 3

Hope this helps :)

Answer 2

Answer:

Answer: The correct answer is 3.

Step-by-step explanation:

Let the number of ninths needed be taken as 'x'

We need to find the number of ninths needed to make;

$(1)/(3)$ ,

The equation for this becomes:

$(1)/(9)* x=(1)/(3)\n\nx=(9)/(3)\n\nx=3$

Hence, we need 3 times ninths to get us the fraction of $(1)/(3)$ .

How do you solve this using additional method elimination
3x + y = 17
4x - y = 18

Answers

// Solve equation [1] for the variable y

[1] y = -3x + 17

// Plug this in for variable y in equation [2]

[2] 4x - (-3x+17) = 18 [2] 7x = 35

// Solve equation [2] for the variable x

[2] 7x = 35 [2] x = 5

// By now we know this much :

x = 5 y = -3x+17

// Use the x value to solve for y

y = -3(5)+17 = 2 Solution : {x,y} = {5,2}

In which of the following stores would you pay the least amount for an item that is priced $360? Store A: Sale of 10% off and a successive discount of 10% off. Store B: Sale of 15% with no additional discount. Store C: Sale of $35 off and a successive discount of 10% off

Answers

The right answer for the question that is being asked and shown above is that: "A: Sale of 10% off and a successive discount of 10% off." The store that would let you pay the least amount for an item that is priced $360 is the Store A.

The correct answer is Store A: Sale of 10% off and a successive discount of 10% off.

Further explanation:

Discount is the reduction of amount in the cost price of any item.

The following formula for discount can be used when the rate of discount and the cost price is given.

$\boxed{{\text{Discount}}=\left( {\frac{{{\text{rate of discount}}}}{{100}}}\right)*{\text{cost price}}}$

The following formula for selling price can be used when the discount and the cost priceis given.

$\boxed{{\text{Selling price}}={\text{Cost price}}-{\text{Discount}}}$

Given:

The price of an item is $\boxed{\$360}$ .

Calculation:

Store A is allowing 10% off and then allowing a successive discount of 10%.

The first discount of an item by the use of the formula can be calculated as,

$\begin{aligned}{\text{discount}}&=\left( {\frac{{10}}{{100}}}\right)* 360\n&= 36\n\end{aligned}$

Now, the selling price after allowing the first discount is,

$\begin{aligned}{\text{Selling price}}&={\text{360}}-36\n&=324\n\end{aligned}$

The successive discount on the item can be calculated as,

$\begin{aligned}{\text{discount}}&=\left( {\frac{{10}}{{100}}}\right)*324\n&=32.4\n\end{aligned}$

Now, the selling price after allowing second discount is,

$\begin{aligned}{\text{Selling price}}&={\text{324}}-32.4\n&=291.6\n\end{aligned}$

Therefore, the amount we have to pay to Store A is $\boxed{\$291.6}$ .

Store B is giving 15% off with no additional discount.

The discount of an item by the use of the formula can be calculated as,

$\begin{aligned}{\text{discount}}&=\left( {\frac{{15}}{{100}}}\right)*360\n&=54\n\end{aligned}$

Now, the selling price after allowing discount can be calculated as,

$\begin{aligned}{\text{Selling price}}&={\text{360}}-54\n&=306\n\end{aligned}$

Therefore, the amount we have to pay to Store B is $\boxed{\$306}$ .

Store C is giving $35 off and then allowing a successive discount of 10%.

Now, the selling price after allowing first discount can be calculated as,

$\begin{aligned}{\text{Selling price}}&={\text{360}}-35\n&=325\n\end{aligned}$

The successive discount on the item can be calculated as,

$\begin{gathered}{\text{discount}}=\left( {\frac{{10}}{{100}}}\right)*325\n=32.5\n\end{gathered}$

Now, the selling price after deducting second discount can be calculated as,

$\begin{aligned}{\text{Selling price}}&={\text{325}}-32.5\n&=292.5\n\end{aligned}$

Therefore, the amount we have to pay to Store C is $\boxed{\$292.5}$ .

It can be clearly seen that if we buy an item which is priced at $360 from Store A then we have to pay least amount of $291.6.

it is not representative of the whole school because you asked only peple at the gym
what if there happened to be 1 person at the gym,
therfor you conclude that 100% of people at school exercise?
rediculus

1. no, becuse yo only asked peple at gym who are probaly exercising or pretenitng to exercise or showing off

2. yes, at the doors of the school or the school cafeteria or where there is a mixed group of people, the more the better, if you can survey the entire school, great

3. that is an either or situation, also people don't like to be called a couch potato so theere will be some people who will lie and say they exercise every day and there will be some peple wo don't want to answer and there will be some who will think you are insulting them and punch you
you will have biased results since you changed the question to the extermes

1. No, the results will only represent how much exercise those people do. 2.A better location would be somewhere like a playground because everyone goes there. At a gym you will only talk to people who do exercise. 3. The results of you answer would be different because there is less of a range of answers. People who don't exercise every day would have to go with the second answer even if they exercised on like 5 days a week. Without those answers you could say that they exercised a lot.

Select the proper order from least to greatest for 1/2, 5/6, 2/7, 4/2?

Answers

Answer: Proper order form least to greatest is given by

$(2)/(7),(1)/(2),(5)/(6),(4)/(2)$

Step-by-step explanation:

Since we have given that

$(1)/(2),(5)/(6),(2)/(7),(4)/(2)$

We need to write it in proper order from least to greatest.

For this we are required to take the L.C.M. of denominators:

1) L.C.M. of 2,6,7,2 = 42

2) Make the denominator 42:

$(1)/(2)* (21)/(21)=(1* 21)/(2* 21)=(21)/(42)\n\n(5)/(6)* (7)/(7)=(5* 7)/(6* 7)=(35)/(42)\n\n(2)/(7)* (6)/(6)=(2*6)/(7* 6)=(12)/(42)\n\n(4)/(2)* (21)/(21)=(4* 21)/(2* 21)=(48)/(42)$

From least to greatest :

$(12)/(42),(21)/(42),(35)/(42),(48)/(42)\n\n(2)/(7),(1)/(2),(5)/(6),(4)/(2)$

the least is 2/7 then 1/2 then 5/6 and the greatest is 4/2

4x=40

/4 /4

x=10

(4*10=40)-6=34

Answer:
