To find equivalent fractions to 7/9, you can multiply or divide both the numerator and denominator by the same non-zero number. For example, multiplying both by 2 gives 14/18, and multiplying by 3 gives 21/27. These fractions are equivalent to 7/9 because they represent the same proportion of a whole.

To determine how many times 12 can go into 940, you would perform a division operation. Divide 940 by 12, which equals 78.33 recurring. Therefore, 12 can go into 940 approximately 78 times with a remainder of 4.

30 times with a remainder of 1, or 30.5

No, that is the number of PERMUTATIONS (not combinations).

With 3 numbers, the number of combinations, including the null combination, is 23 = 8.

With the three numbers 1,2 and 3, these would be

{None of them}, {1), {2), {3}, {1, 2}, {1, 3}, {2, 3}, {1, 2, 3}.

The calendar for the year 1987 will repeat exactly in the year 2018. This is because the Gregorian calendar repeats every 28 years. The calendar for any specific year will repeat in the year that is a multiple of 28 years later.

The expression 4x - 3y - 5x - 2y can be simplified by combining like terms. Like terms have the same variables raised to the same powers. In this case, the x terms are like terms and the y terms are like terms. Combining the x terms, we get -x, and combining the y terms, we get -5y. Therefore, the simplified expression is -x - 5y.

Well, darling, the highest common factor of 77 and 217 is 7. It's as simple as that. No need to complicate things, honey. Just remember to keep it sassy and straightforward, okay?

To subtract 7x^3 - 5x^4, you first need to rearrange the terms in descending order of the exponents. So, the expression becomes -5x^4 - 7x^3. Since the terms have different exponents, you cannot directly subtract them. The result is simply -5x^4 - 7x^3.

Well, honey, a cone can't roll in a straight line because of its shape. It's like asking a square to roll smoothly without wobbling. Physics just ain't gonna let that happen, sweetie. So, in short, no, a cone can't roll in a straight line.

Half of 6 is 3. Half of 8 is 4. 7 is not an even number, so half of 7 will not be a round number. Half of 7 is halfway between half of 6 and 8-halfway between 3 and 4. So half of 7 is 3.5

Additionally, you could multiply 7 by .5 to divide it in half. Your answer will be 3.5, for the reason explained above.

That equation is,

q(Joules) = mass * specific heat ( symbol is C ) * (delta, a triangle) change in temperature

That is to say delta means,

Temperature Final - Temperature Initial

q is a constant and not subject to change as temperature is

You cannot find the answer to an expression!!!

An expression needs to be EQUATED' to a value, for another value to be found.

2x^(2) + 5x + 12 is an EXPRESSION. Impossible to find an value for 'x'.

However,

2x^(2) + 5x + 12 = 0 is an EQUATION and a result can be calculated.

Nothing!!!!! , Because 'pie' is the pie that you eat, like Apple pie, or Meat pie.

If you mean 'pi' , note the spelling, then this refers to the constant of proportion of circles.

Circumference = constant of proportion X diameter,

Algebraically written as : -

C = kd Where 'k' os the constant of proportion, and for circles it is given the name 'pi'

For circles however large or small have 'pi' as the constant.

'pi' has the numerical value of 3.141592... Which is an IRRATIONAL numbe. and is approximated to 3.14, 3.1416, 22/7 for school learning purposes.

'pi' is the small case letter 'p' from the Classical Greek Alphabet, and refers to constant of PROPORTION. As a Classical Greek letter, it looks like a set of football goalposts, with a curved leg on one side.

Casually , IRRATIONAL means that the decimal digits recur to infinity, AND the decimal digits are NOT in any regular order. What you are given in school ( 3.14 etc.,) is only an approximation. Supa Dupa computere have calculated 'pi' to at least 50 billion places and still going!!!!!

Hope that helps!!!!!

10 mm x 6.0 m

= 10 mm x 6(1,000 mm)

= 10 mm x 6,000 mm

= (10 x 6,000) (mm x mm)

= 60,000 mm^2

Oh, dude, a reflex angle is greater than 180 degrees, so if you draw one arm of the angle straight, the other arm would have to be pointing backwards, which is like, not really a thing in normal geometry. So, technically, no, you can't have a straight angle and a reflex angle sharing an arm. But hey, if you're feeling creative, go for it, who am I to stop you?

Well, isn't that a happy little question! The Highest Common Factor (HCF) of 630 and 294 is 42. Just like painting a beautiful landscape, finding the HCF is about looking for the largest number that can divide evenly into both 630 and 294, creating a harmonious result. Just remember, there are no mistakes in math, only happy little accidents!

Well, isn't that just a happy little question! To find the length of wire used to form a cuboid, you would need to add up the perimeter of the base (length + width) and multiply it by 4, as there are 4 sides to a cuboid. Then, you add the perimeter of the base to the height of the cuboid. Just remember, there are no mistakes, only happy little accidents in math!

The Highest Common Factor (HCF) of 294 and 420 is the largest number that divides both 294 and 420 without leaving a remainder. To find the HCF, you can use methods such as prime factorization or the Euclidean algorithm. In this case, the prime factorization of 294 is 2 x 3 x 7 x 7, and the prime factorization of 420 is 2 x 2 x 3 x 5 x 7. Therefore, the HCF of 294 and 420 is 2 x 3 x 7, which equals 42.

The greatest common divisor (GCD) of two numbers is the largest positive integer that divides both numbers without a remainder. To find the GCD of 2233 and 25193, you can use the Euclidean algorithm. By repeatedly applying the algorithm, you will find that the GCD of 2233 and 25193 is 59.

Well, honey, the sum of the angles in a triangle is always 180 degrees. So, if you have two angles at 35 degrees and 60 degrees, just subtract that from 180 to find the measure of the third angle. In this case, the third angle would be 85 degrees. Math doesn't have to be complicated, darling.

The formula for circumference is

c = pi*diameter

and the formula for area is

a = pi*r^2

Therefore, the circumference is 9.3*pi

and the area is pi*(4.65)^2

*4.65 since the radius is half the diameter*

*You could substitute pi with 3.14, though leaving your answers in terms of pi is better*
