The 0.317 spray bottle did she ​us.

It is required to find how much of the bottle did she ​use.

A fraction having whole numbers for the numerator and denominator. A fraction is a number of the form: ab where a and b are integers and b≠0. It represents the division of two numbers.

Given:

We know that total =1

For a cleaning solution=3/7 of a spray bottle

Used=1/9

According to given question we have,

Subtract the fractions

3/7 - 1/9

Calculate the difference,

=20/63

=0.317

Therefore, the 0.317 spray bottle did she ​us.

Answer:

The two equations (representing value of variable Y) can be equated and converted into one single equation with X variable only

Step-by-step explanation:

If the starting of both the equation is from "Y=" then it means that whatever equation (having x variable) they are representing will be equal to each other as both the equation on one side are ultimately equal to Y

For example

Y = 3X + 5 ---- Eq (1)

Y = 7X +6  ---- Eq (2)

So both are equal

3X + 5 = 7X + 6

4X + 1 = 0

In this way the two equations (representing value of variable Y) can be equated and converted into one single equation with X variable only

Another statement is, "Volume is directly proportional to the number of moles."

The volume increases as the number of moles increases. It does not depend on the sizes or the masses of the molecules.

Equal volumes of hydrogen, oxygen, or carbon dioxide contain the same number of molecules.

STP is 0 °C and 1 bar.

One mole of an ideal gas occupies 22.71 L at STP. Thus, its molar volume at STP is 22.71 L

Example Problem

A 6.00 L sample at 25.0 °C and 2.00 atm contains 0.500 mol of gas. If we add 0.250 mol of gas at the same pressure and temperature, what is the final total volume of the gas?

Answer:

Step-by-step explanation:

The formula for compound annual interest is  A = P(1 + r)t  where  

A = Accumulated or final amount  (double $500 = $1000)  

P = Principal or original amount  ($500)  

r = Rate as a decimal (0.08)

t = Time in years  

1000 = 500(1 + 0.08)t

2 = 1.08t  

Take the logarithm of both sides.  I prefer the natural logarithm ln, but if you're more comfortable with base 10 logs they will work just as well  

ln(2) = ln(1.08t)  

ln(2) = t*ln(1.08)

t = ln(2)/ln(1.08)

t = 9.0065 years  

Check:  500*1.089.0065 = $1000

Answer:

how to add and subtract fractions

Step-by-step explanation:

ok so we can start with adding so when you add fractions you can first start out by making the denominators the same number to make it easier so here is an example

7/9 + 3/10  you could make the denomonatiers the same or just do 9x10 and 7x10 + 3x9 and 10x9 and then if you multiply the numbers and added up all the sums you would get to fractions 70/90 + 27/90 so you add them up and science the denominators are the same you just leave them the same number so it would just be 70+27 so you would get 97/90 and because the denominator is 90 and we have 97 for the numerator 97 fits into 90 1 time with 7 left over   so the whole number would be 1 and then 7/90

Given:

Point (7,12) is rotated 1260° counterclockwise about the origin.

To find:

The  x-coordinate of the point after this rotation.

Solution:

If a point is rotated 360 degrees then its coordinates remains unchanged.

If a point is rotated 180 counterclockwise about the origin degrees, then

[tex](x,y)\to (-x,-y)[/tex]

We know that,

[tex]1260^\circ=1080^\circ+180^\circ[/tex]

[tex]1260^\circ=3\times 360^\circ+180^\circ[/tex]

After [tex]3\times 360^\circ[/tex] rotation the coordinates of points remains same, i.e., (7,12). So, after that (7,12) is rotated 180° counterclockwise about the origin.

[tex](7,12)\to (-7,-12)[/tex]

The point (7,12) becomes (-7,-12) after rotation of  1260° counterclockwise about the origin.

Therefore, the x-coordinate of the required point is -7.

Answer: $540

Step-by-step explanation:

If Milo works 40 hours for the week, he earns $12.00 per hour.

If Milo works anything over $40, he makes 1 times his normal pay which means that he is making the same amount over 40 hours as he is under 40 hours.

If he works 45 hours therefore, his pay is:

= 45 * 12

= $540

Answer:

546

Step-by-step explanation:

The lateral area is made up of 4 faces that do not includes the bases.

2 faces have dimensions 2.5 ft by 21 ft.

2 faces have dimensions 10.5 ft by 21 ft.

LA = 2 * 2.5 ft * 21 ft + 2 * 10.5 ft * 21 ft

LA = 105 ft^2 + 441 ft^2

LA = 546 ft^2

Answer:

28

Step-by-step explanation:

6(2) + 7(3) - 5

12 + 21 -5

It's a good idea to get into the habit of using parenthses

when substituting numbers in for variables.

Since x = 2 and y = 3, 6x + 7y - 5 is 6(2) + 7(3) - 5.

Simplifying from here, we get 12 + 21 - 5 or 33 - 5 which is 28.

hope this helps

have a good day :)

Step-by-step explanation:

2 + 6m +7=57

9+6m=57 add like terms

6m=48 subtract 9 from each side

m=8 divide by 6 on each side

Answer:

M=8

Step-by-step explanation:

First your going to subtract 2 from 7 and thats 5.

then your going to do:

6m+5=57

Then subtract 5 from 57 and thats 52

and divide 52 from 6 and thats 8.

Answer:

12.66 cm

Step-by-step explanation:

Area of the circle = 125.8 Sq cm

[tex] \therefore \: \pi {r}^{2} = 125.8 \\ \\ \therefore \: 3.14 \times {r}^{2} = 125.8 \\ \\ {r}^{2} = \frac{125.8}{3.14} \\ \\ {r}^{2} = 40.0636943 \\ \\ {r} = \sqrt{40.0636943} \\ \\ r = 6.32958879 \\ \\ r \approx \: 6.33 \: cm \\ \\ d \: = 2r \\ \\ d = 2 \times 6.33 \\ \\ d = 12.66 \: cm \\ [/tex]

Diameter of the circle = 12.66 cm

Since, circumference of the circle touches each of the four sides of the square.

So, length of the sides of the square

= diameter of the circle.

= 12.66 cm

Answer:cost for basket ball= $8 and

cost of baseball = $2

Step-by-step explanation:

Step 1

Let the cost of basket ball be represented as x

and cost of  baseball = y          such that

Four basketballs and six baseballs cost $44 will be expressed as

4x+ 6y= 44  --- eqn 1   also

Five basketballs and four baseballs costs $48 will be expressed as

5x+ 4y= 48--- eqn 2

Step 2

Having obtained two expressions we can now sole

4x+ 6y= 44  --- eqn 1

5x+ 4y= 48--- eqn 2

multiplying eqn 1 by 5 and eqn 2 by 4

20x+ 30y =220---- eqn 3

20x+ 16y=192-----eqn 4

subtracting equation 4 from 3   we now have

14y=28

y= 28/14

y=2 = $2

from equation 1

4x+ 6y= 44, putting the value of y=7 to find x

4x+ 6(2)= 44

4x+12= 44

4x= 44-12

4x=32

x= 32/4

x=8=$8

cost for basket ball= $8 and

cost of baseball = $2
