Answer:
2 8/9
Step-by-step explanation:
1. Convert to impromper fractions (like 12/4 for example)
6 1/2 as improper fraction would be 6 *2 +1, first you do 6 x 2, to get 12, then you add 1, so 6 1/2 as an imporper fraction would be 13/4.
2 1/4 as imporper fraction would be 2 x 4 +1, first you do 2 x 4, to get 8, then you add 1, so 2 1/4 as an imporper fraction would be 9/4.
2. Second you multiply 13/4 x 9/4
To mutiply 13/4 x 9/4, you need to cross multiplication. Cross multiplication - a x c over b x d . You should get 13x 2 / 1 x 9 , so 13/4 x 9/4, would be 26/9.
3. Convert 26/9 to mixed number, which would be 2 8/9.
Answer:
[tex]\displaystyle 2\frac{8}{9}[/tex]
Step-by-step explanation:
[tex]\displaystyle 6\frac{1}{2} \div 2\frac{1}{4} \hookrightarrow \frac{13}{2} \div \frac{9}{4} \hookrightarrow \boxed{2\frac{8}{9}} = \frac{1\frac{4}{9}}{\frac{1}{2}}[/tex]
OR
[tex]\displaystyle 6\frac{1}{2} \div 2\frac{1}{4} \hookrightarrow \frac{13}{2} \div \frac{9}{4} \hookrightarrow \frac{26}{9} = \frac{13}{2} \times \frac{4}{9} \\ \\ \boxed{2\frac{8}{9}}[/tex]

Answer:
Step-by-step explanation:
To find the angles of any shape with all sides equal in length, we use the formula:
[tex]\frac{(n-2)*180}{n}[/tex] , where n is the number of sides
For a pentagon, we get the equation:
[tex]\frac{(5-2)*180}{5}[/tex][tex]= 108 degrees[/tex]
Thus the measure of each in a pentagon if the lengths of all five sides are equal is 108 degrees.

PLEASE HELP ME ! Convert the following description to a proper scale ratio:
8.4 cm represents an actual distance of 33.6 km.
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

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

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

Answer: 8/125
Step-by-step explanation:
its called inverse and isolation i think So basically solving for the variable.
Here'sthe definition if it helps
Inverse operations are pairs of mathematical manipulations in which one operation undoes the action of the other—for example, addition and subtraction, multiplication and division. The inverse of a number usually means its reciprocal, i.e. x - 1 = 1 / x . The product of a number and its inverse (reciprocal) equals 1.
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
Write an equation to help Stacy find the gravitational force on an object if she knows the mass. In the equation, let W represent gravitational force, m represent mass, and g represent the ratio you found in part D. Test your equation using a set of values from the table to be sure it works
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.

How to find the percentage from the total value?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.

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.

(I'M GIVING BRAINLY FOR BEST ANSWER) In the formula h = gd, find the value of d if g = 12.3 and h = 17.4.
create an example (with animals like cats or doggos for more chance for yours being the "best answer") and explain how to get the answer to that example in 10 sentences, no less
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.

Paula spent 3/8 of her allowance on clothes and 1/6 on entertainment. What fraction of her allowance did she spend on the other items?
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

The students in Mr. Nottingham’s class are writing expressions for
the perimeter of a rectangle that has a side length of l and a

Sergio: 2(l + w)
Jamie: l + w + l + w
Karina: 2l + w
Ethan: 2w + 2l
l

Finish each sentence by explaining how each student was thinking
about finding the rectangle’s perimeter:
Sergio’s strategy was to…
Jamie’s strategy was to…
Karina’s strategy was to…
Ethan’s strategy was to…
Which of the students are correct? If a student was incorrect,
explain what they did wrong.
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!
