Answer:

11/24

Step-by-step explanation:

x=1-(3/8+1/6)

so

x=1-(13/24)=11/24

sorry if i need any.

Answer:

11/24

Step-by-step explanation:

you have to make the denominators the same.

to do that, you must find the LCM (Least Common Multiple) of the denominators which are 6 and 8.

Multiples of 6: 6, 12, 18, 24 (6 multiplied by 4 = 24)

Multiples of 8: 8, 16, 24 (8 multiplied by 3 = 24)

the LCM of 6 and 8 is 24 - this means that the smallest number that BOTH 6 and 8 can be divided into, WITHOUT leaving a remainder is 24.

From there, you multiply the ENTIRETY of each fraction by the number the denominator multiplies by to get 24:

3/8 multiplied by 3/3 = 9/24

1/6 multiplied by 4/4 = 4/24

NB: If you wish to check if your new and your old fractions are the same, all you have to do is simplify the new fractions and see whether or not you get back the old ones.

Next, you add the new fractions:

9/24 + 4/24 = 13/24

To get the allowance that she spent on other items:

24/24 (which is equal to 1 or 1 whole) - 13/24

This then results in 11/24 which is your answer

Answer:

4.21$

Step-by-step explanation:

Because his total bill is 5.79$

If he pays with a 10$ bill meaning he get's 4.21$ back.

To calculate this we could subtract 5.79 by 10

Add to 5.79 lentil 10

Subtraction would look like this.

10.00$

 5.79$

Since 0 can't subtract nine he goes to his neighbor 0 for help but he can't help so his neighbor 0 also goes for help to his neighbor  0 but he still can't help so then he goes to 1 and puts a 1 in front of 0 to make it 10

And then 0 that turned in to 10 helps other 0 to go to a 9 and it turn into 10 and then that 0 helps that least 0 to turn into 10.

So what's 10 -9=1

9-7=2 so now we got .21

And last to get out final number what is 9 - 5=4 and finally makes 4.21 and that's our answer.

Hope this helps have a great day:)

Answer:

? = 500

Step-by-step explanation:

-589 + 90 = -499

-499 + (-1) = -500

-500 + ? = 0

? = 500

i hope this helps! have a wonderful rest of ur day :)

and if its not too much to ask could you mark me as brainliest, im trying to rank up this month and i only need 2 more, if not thats ok! ty and tell me if theres anythign else you need help with!!

Hey there!

-589 + ? + 90 + (-1) = 0

CONVERT the EQUATION

-589 + x + 90 - 1 = 0

COMBINE the LIKE TERMS

x - (-589 + 90 - 1) = 0

x - 589 + 90 - 1 = 0

x - 499 - 1 = 0

x - 500 = 0

ADD 500 to BOTH SIDES

x - 500 + 500 = 0 + 500

CANCEL out: -500 + 500 because it give you 1

KEEP: 0 + 500 because it give you the x-value

NEW EQUATION: x = 0 + 500

SIMPLIFY IT!

x = 500

Therefore, your answer is: 500

Good luck on your assignment & enjoy your day!

Answer:

  1 : 400,000

Step-by-step explanation:

A map scale is usually represented as a unit fraction, one with 1 in the numerator. It has no units, which is to say that it is the ratio of same units.

It can be found by dividing the map dimension by the ground dimension when both are expressed in the same units.

  (8.4 cm) / (33.6 km) = (8.4×10^-2 m) / (33.6×10^3 m) = (8.4/33.6)×10^-5

  = 0.25×10^-5 = 1/400,000

Additional comment

Map scales are often expressed using the colon for the ratio unit separator:

  1 : 400,000

Answer: 25.12

Step-by-step explanation:

Formula for Volume of Cylinder - π x r² x h

First you want to find the area of the base.

π x 2² x 2

3.14 x 2² x 2

= 25.12

Answer: 25.1 cm'3

Step-by-step explanation:

h = 2 and d =4 and r= 2 (the radius is half of the diameter)

v = πr 2h

v + π(2)'2(2)

v = 25.132741228718

v = 25.1 cm '3

Answer: 1.41463414634 or 1.41 If Rounding

Step-by-step explanation:

In this situation, you are multiplying g or 12.3 and d in order to get a product of h or 17.4. In order to get the value of d, you would need to use the Inverse Operation. Since here we are multiplying, we would do the opposite which is division so you would do the product or 17.4 divided by the factor or 12.3 to get 1.41.

17.4/12.3 = 1.41

To check if our answer is right we would do 1.41 multiplied by 12.3.

1.41 x 12.3 = 17.343

Approximately 17.4.

Can't think of an example but I hope this helps. Good luck in your exam! :>

Answer:

Gravitation force is well known word in physics. Gravity force exists in all masses objects, i.e. all the object which have masses. The gravitational force is exhibited from the lighter mass to heavier mass.

The expression for the gravitational force is,

Here, F is the gravitational force, G is the gravitational constant,  is the mass of one object,  is the mass of another object, and R is the distance between the two objects.

Thus, the gravitational force is directly proportional to the product of the mass of the massive objects and inversely proportional to the square of the distance between the objects. This is known as Newton's law of gravitation.

Answer:

Sergio's strategy was to multiply the sum of the length and width of the rectangle by 2. This was one correct way to find the perimeter of the rectangle.

Jamie's strategy was to add the given measurements of the length and width of the rectangle together. This was another correct way to find the perimeter of the rectangle.

Karina's strategy was to multiply the given length of the rectangle by 2 and add this product to the width of the rectangle. This was NOT a correct way to find the perimeter of the rectangle, as it did not follow the formulas to finding the perimeter of a rectangle: l + w + l + w, or 2(l + w) and furthermore formulas that explain the same thing. Karina only multiplied the length by 2 and did not account for the width of the retangle which she should have done as well.  

Ethan's strategy was to multiply the width by 2, multiply the length by 2, and add these two products together to find the perimenter. This final strategy was correct, and can be used to find the perimeter of the rectangle.

Hope this helps you! I love doing math, so enjoy!

Alright, all the equations are correct, but only two will figure out how many 1/2 servings she can make.

Your answers are A and D.

A adds the ingredients together for the total, 16, and D shows how many servings you can make. If you're making 1/2 pound servings, then the equation

16 / 1/2

would turn into

16/1 * 2/1

and that would turn into

16*2

which equals

=32

Step-by-step explanation:

Answer:

The addition of 4 liters of 25% solution to 6 liters of 50% solution produces 10 liters of 40% solution.

Hope this helps.

Super sorry if it doesn't.

The number of liters of each type of solution did the chemist use to make the new solution is 3.

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

We need to Write the percent as a fraction in simplest form

16.24%

So, we can rewrite it as;

16.24 / 100

16 and 24/100 or 16 6/25

So the percent as a fraction is 16 6/25

We are given that;

Solution A = 15% acid

Solution B = 30% acid

Now,

We can isolate x from the first equation and substitute it into the second equation.

x = 12 - y 0.15(12 - y) + 0.30y = 3 1.8 - 0.15y + 0.30y = 3 0.15y = 1.2 y = 8

Then, we can plug in y into either equation to find x.

x = 12 - y x = 12 - 8 x = 4

Check the solution. We can check if our solution satisfies both equations by plugging in x and y into them.

x + y = 12 4 + 8 = 12 12 = 12

0.15x + 0.30y = 3 0.15(4) + 0.30(8) = 3 0.6 + 2.4 = 3 3 = 3

Therefore, by the given percentage the answer will be 3.

A square pyramid consists of a square base and four triangles connected to a vertex. Its base is a square and the side faces are triangles with a common vertex.

Answer:

  p = 5/8

Step-by-step explanation:

We use the inverse of the addition of the constant to isolate the variable p. We do this using the subtraction property of equality: subtracting the same number from both sides of the equation leaves the value of the variable unchanged.

  7/8 = 1/4 + p . . . . . given

  7/8 -1/4 = 1/4 -1/4 +p . . . . subtract 1/4 from both sides

  5/8 = p . . . . . . . . simplify

  p = 5/8
